In recent years, with the rapid development of science and technology, the application of single chip is accepted broadly in real-time detection and automatic control of microcomputer. Although it’s often act as the core component of single chip system, it is not enough only with the knowledge of single chip. Engineers also need to think about the structure of the hardware to perfect the system.
Currently most higher ecation institutions have built single chip laboratory, equipped with experiment box and other hardware simulation equipment. But the circuitry of the experiment box is fixed and the experiment steps are hard to be changed. It is not fit the trend of rapid development speed of single chip technology. It is also unsuited to develop students’ abilities and creativities. With the introction of the Proteus software simulation technology, it can be solved at a certain extent.

Introction of Programmable controllers
From a simple heritage, these remarkable systems have evolved to not only replace electromechanical devices, but to solve an ever-increasing array of control problems in both process and nonprocess instries. By all indications, these microprocessor powered giants will continue to break new ground in the automated factory into the 1990s.
HISTORY
In the 1960s, electromechanical devices were the order of the day ass far as control was concerned. These devices, commonly known as relays, were being used by the thousands to control many sequential-type manufacturing processes and stand-along machines. Many of these relays were in use in the transportation instry, more specifically, the automotive instry. These relays used hundreds of wires and their interconnections to effect a control solution. The performance of a relay was basically reliable - at least as a single device. But the common applications for relay panels called for 300 to 500 or more relays, and the reliability and maintenance issues associated with supporting these panels became a very great challenge. Cost became another issue, for in spite of the low cost of the relay itself, the installed cost of the panel could be quite high. The total cost including purchased parts, wiring, and installation labor, could range from $30~$50 per relay. To make matters worse, the constantly changing needs of a process called for recurring modifications of a control panel. With relays, this was a costly prospect, as it was accomplished by a major rewiring effort on the panel. In addition these changes were sometimes poorly documented, causing a second-shift maintenance nightmare months later. In light of this, it was not uncommon to discard an entire control panel in favor of a new one with the appropriate components wired in a manner suited for the new process. Add to this the unpredictable, and potentially high, cost of maintaining these systems as on high-volume motor vehicle proction lines, and it became clear that something was needed to improve the control process – to make it more reliable, easier to troubleshoot, and more adaptable to changing control needs.
That something, in the late 1960s, was the first programmable controller. This first ‘revolutionary’ system wan developed as a specific response to the needs of the major automotive manufacturers in the United States. These early controllers, or programmable logic controllers (PLC), represented the first systems that 1 could be used on the factory floor, 2 could have there ‘logic’ changed without extensive rewiring or component changes, and 3 were easy to diagnose and repair when problems occurred.
It is interesting to observe the progress that has been made in the past 15 years in the programmable controller area. The pioneer procts of the late 1960s must have been confusing and frightening to a great number of people. For example, what happened to the hardwired and electromechanical devices that maintenance personnel were used to repairing with hand tools? They were replaced with ‘computers’ disguised as electronics designed to replace relays. Even the programming tools were designed to appear as relay equivalent presentations. We have the opportunity now to examine the promise, in retrospect, that the programmable controller brought to manufacturing.
All programmable controllers consist of the basic functional blocks shown in Fig. 10. 1. We’ll examine each block to understand the relationship to the control system. First we look at the center, as it is the heart ( or at least the brain ) of the system. It consists of a microprocessor, logic memory for the storage of the actual control logic, storage or variable memory for use with data that will ordinarily change as a function power for the processor and memory. Next comes the I/O block. This function takes the control level signals for the CPU and converts them to voltage and current levels suitable for connection with factory grade sensors and actuators. The I/O type can range from digital (discrete or on / off), analog (continuously variable), or a variety of special purpose ‘smart’ I/O which are dedicated to a certain application task. The programmer is shown here, but it is normally used only to initially configure and program a system and is not required for the system to operate. It is also used in troubleshooting a system, and can prove to be a valuable tool in pinpointing the exact cause of a problem. The field devices shown here represent the various sensors and actuators connected to the I/O. These are the arms, legs, eyes, and ears of the system, including push buttons, limit switches, proximity switches, photosensors, thermocouples, RTDS, position sensing devices, and bar code reader as input; and pilot lights, display devices, motor starters, DC and AC drives, solenoids, and printers as outputs.
No single attempt could cover its rapidly changing scope, but three basic characteristics can be examined to give classify an instrial control device as a programmable controller.
(1) Its basic internal operation is to solve logic from the beginning of memory to some specified point, such as end of memory or end of program. Once the end is reached, the operation begins again at the beginning of memory. This scanning process continues from the time power is supplied to the time it it removed.
(2) The programming logic is a form of a relay ladder diagram. Normally open, normally closed contacts, and relay coils are used within a format utilizing a left and a right vertical rail. Power flow (symbolic positive electron flow) is used to determine which coil or outputs are energized or deenergized.
(3) The machine is designed for the instrial environment from its basic concept; this protection is not added at a later date. The instrial environment includes unreliable AC power, high temperatures (0 to 60 degree Celsius), extremes of humidity, vibrations, RF noise, and other similar parameters.
General application areas
The programmable controller is used in a wide variety of control applications today, many of which were not economically possible just a few years ago. This is true for two general reasons: 1 there cost effectiveness (that is, the cost per I/O point) has improved dramatically with the falling prices of microprocessors and related components, and 2 the ability of the controller to solve complex computation and communication tasks has made it possible to use it where a dedicated computer was previously used.
Applications for programmable controllers can be categorized in a number of different ways, including general and instrial application categories. But it is important to understand the framework in which controllers are presently understood and used so that the full scope of present and future evolution can be examined. It is through the power of applications that controllers can be seen in their full light. Instrial applications include many in both discrete manufacturing and process instries. Automotive instry applications, the genesis of the programmable controller, continue to provide the largest base of opportunity. Other instries, such as food processing and utilities, provide current development opportunities.
There are five general application areas in which programmable controllers are used. A typical installation will use one or more of these integrated to the control system problem. The five general areas are explained briefly below.
Description
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the instry-standard MCS-51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
Function characteristic
The AT89C51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full plex serial port, on-chip oscillator and clock circuitry. In addition, the AT89C51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.
Pin Description
VCC：Supply voltage.
GND：Ground.
Port 0：
Port 0 is an 8-bit open-drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as highimpedance inputs.Port 0 may also be configured to be the multiplexed loworder address/data bus ring accesses to external program and data memory. In this mode P0 has internal pullups.Port 0 also receives the code bytes ring Flash programming,and outputs the code bytes ring programverification. External pullups are required ring programverification.
Port 1
Port 1 is an 8-bit bi-directional I/O port with internal pullups.The Port 1 output buffers can sink/source four TTL inputs.When 1s are written to Port 1 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pullups.Port 1 also receives the low-order address bytes ring Flash programming and verification.
Port 2
Port 2 is an 8-bit bi-directional I/O port with internal pullups.The Port 2 output buffers can sink/source four TTL inputs.When 1s are written to Port 2 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 2 pins that are externally being pulled low will source current, because of the internal pullups.Port 2 emits the high-order address byte ring fetches from external program memory and ring accesses to external data memory that use 16-bit addresses. In this application, it uses strong internal pullupswhen emitting 1s. During accesses to external data memory that use 8-bit addresses, Port 2 emits the contents of the P2 Special Function Register.Port 2 also receives the high-order address bits and some control signals ring Flash programming and verification.
Port 3
Port 3 is an 8-bit bi-directional I/O port with internal pullups.The Port 3 output buffers can sink/source four TTL inputs.When 1s are written to Port 3 pins they are pulled high by the internal pullups and can be used as inputs. As inputs,Port 3 pins that are externally being pulled low will source current (IIL) because of the pullups.Port 3 also serves the functions of various special features of the AT89C51 as listed below:
Port 3 also receives some control signals for Flash programming and verification.
RST
Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device.
ALE/PROG
Address Latch Enable output pulse for latching the low byte of the address ring accesses to external memory. This pin is also the program pulse input (PROG) ring Flash programming.In normal operation ALE is emitted at a constant rate of 1/6 the oscillator frequency, and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped ring each access to external Data Memory.
If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only ring a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution mode.
PSEN
Program Store Enable is the read strobe to external program memory.When the AT89C51 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped ring each access to external data memory.
EA/VPP
External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset.EA should be strapped to VCC for internal program executions.This pin also receives the 12-volt programming enable voltage(VPP) ring Flash programming, for parts that require12-volt VPP.
XTAL1
Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
XTAL2
Output from the inverting oscillator amplifier.
Oscillator Characteristics
XTAL1 and XTAL2 are the input and output, respectively,of an inverting amplifier which can be configured for use as an on-chip oscillator, as shown in Figure 1.Either a quartz crystal or ceramic resonator may be used. To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 2.There are no requirements on the ty cycle of the external clock signal, since the input to the internal clocking circuitry is through a divide-by-two flip-flop, but minimum and maximum voltage high and low time specifications must be observed.
Figure 1. Oscillator Connections Figure 2. External Clock Drive Configuration
Idle Mode
In idle mode, the CPU puts itself to sleep while all the onchip peripherals remain active. The mode is invoked by software. The content of the on-chip RAM and all the special functions registers remain unchanged ring this mode. The idle mode can be terminated by any enabled interrupt or by a hardware reset.It should be noted that when idle is terminated by a hard ware reset, the device normally resumes program execution,from where it left off, up to two machine cycles before the internal reset algorithm takes control. On-chip hardware inhibits access to internal RAM in this event, but access to the port pins is not inhibited. To eliminate the possibility of an unexpected write to a port pin when Idle is terminated by reset, the instruction following the one that invokes Idle should not be one that writes to a port pin or to external memory.
Power-down Mode
In the power-down mode, the oscillator is stopped, and the instruction that invokes power-down is the last instruction executed. The on-chip RAM and Special Function Registers retain their values until the power-down mode is terminated. The only exit from power-down is a hardware reset. Reset redefines the SFRs but does not change the on-chip RAM. The reset should not be activated before VCC is restored to its normal operating level and must be held active long enough to allow the oscillator to restart and stabilize.
Program Memory Lock Bits
On the chip are three lock bits which can be left unprogrammed (U) or can be programmed (P) to obtain the additional features listed in the table below.
When lock bit 1 is programmed, the logic level at the EA pin is sampled and latched ring reset. If the device is powered up without a reset, the latch initializes to a random value, and holds that value until reset is activated. It is necessary that the latched value of EA be in agreement with the current logic level at that pin in order for the device to function properly

1. About SCM
It can be said across the twentieth century, the three "electric" era, that is, electrical era, the electronic age, and has now entered the computer age. However, such a computer, usually refers to the personal computer, referred to as PC. It consists of the host, keyboard, monitor etc.. Another type of computer, most people do not know how. This computer is to smart to give a variety of mechanical microcontroller (also known as micro-controller). As the name suggests, this computer system only used the smallest one IC, you can perform simple operations and control. Because of its small size, usually hidden in a charged mechanical "stomach" Lane. It is the entire device, like the human brain plays a role, it goes wrong, the whole device was paralyzed.
Now, this MCU has a very wide field of use, such as smart meters, real-time instrial control, communications equipment, navigation systems, home appliances and so on. Once the microcontroller were using a variety of procts, you can serve to upgrade the effectiveness of the proct, often in the proct name is preceded by the adjective - "smart", such as washing machines and so intelligent. At present, some technical personnel of factories or other amateur electronics developers to engage in out of certain procts, not the circuit is too complex, that is, functions are too simple and easy to be copied. The reason may be stuck in the proct without the use of a microcontroller or other programmable logic device.
SCM basic component is a central processing unit (CPU in the computing device and controller), read-only memory (usually expressed as a ROM), read-write memory (also known as Random Access Memory MRAM is usually expressed as a RAM) , input / output port (also divided into parallel port and serial port, expressed as I / O port), and so composed. In fact there is also a clock circuit microcontroller, so that ring operation and control of the microcontroller, can rhythmic manner. In addition, there are so-called "break system", the system is a "janitor" role, when the microcontroller control object parameters that need to be intervention to reach a particular state, can after this "janitor" communicated to the CPU, so that CPU priorities of the external events to take appropriate counter-measures.
单片机的简介
可以说，二十世纪跨越了三个“电”的时代，即电气时代、电子时代和现已进入的电脑时代。不过，这种电脑，通常是指个人计算机，简称PC机。它由主机、键盘、显示器等组成。还有一类计算机，大多数人却不怎么熟悉。这种计算机就是把智能赋予各种机械的单片机（亦称微控制器）。顾名思义，这种计算机的最小系统只用了一片集成电路，即可进行简单运算和控制。因为它体积小，通常都藏在被控机械的“肚子”里。它在整个装置中，起着有如人类头脑的作用，它出了毛病，整个装置就瘫痪了。
现在，这种单片机的使用领域已十分广泛，如智能仪表、实时工控、通讯设备、导航系统、家用电器等。各种产品一旦用上了单片机，就能起到使产品升级换代的功效，常在产品名称前冠以形容词——“智能型”，如智能型洗衣机等。现在有些工厂的技术人员或其它业余电子开发者搞出来的某些产品，不是电路太复杂，就是功能太简单且极易被仿制。究其原因，可能就卡在产品未使用单片机或其它可编程逻辑器件上。
单片机的基本组成是由中央处理器（即CPU中的运算器和控制器）、只读存贮器（通常表示为ROM）、读写存贮器（又称随机存贮器通常表示为RAM）、输入/输出口（又分为并行口和串行口，表示为I/O口）等等组成。实际上单片机里面还有一个时钟电路，使单片机在进行运算和控制时，都能有节奏地进行。另外，还有所谓的“中断系统”，这个系统有“传达室”的作用，当单片机控制对象的参数到达某个需要加以干预的状态时，就可经此“传达室”通报给CPU，使CPU根据外部事态的轻重缓急来采取适当的应付措施。

Getting Started with µVision2
The Keil Software 8051 development tools listed below are programs you use to compile your C code, assemble your assembly source files, link and locate object moles and libraries, create HEX files, and debug your target program.
µVision2 for Windows™ is an Integrated Development Environment that combines project management, source code editing, and program debugging in one single, powerful environment.
The C51 ANSI Optimizing C Cross Compiler creates relocatable object moles from your C source code.
The A51 Macro Assembler creates relocatable object moles from your 8051 assembly source code.
The BL51 Linker/Locator combines relocatable object moles created by the C51 Compiler and the A51 Assembler into absolute object moles.
The LIB51 Library Manager combines object moles into libraries that may be used by the linker.
The OH51 Object-HEX Converter creates Intel HEX files from absolute object moles.
The RTX-51 Real-time Operating System simplifies the design of complex, time-critical software projects.
Software Development Cycle
When you use the Keil Software tools, the project development cycle is roughly the same as it is for any other software development project.
1. Create a project, select the target chip from the device database, and configure the tool settings.
2. Create source files in C or assembly.
3. Build your application with the project manager.
4. Correct errors in source files.
5. Test the linked application.
µVision2 IDE
The µVision2 IDE combines project management, a rich-featured editor with interactive error correction, option setup, make facility, and on-line help. Use µVision2 to create your source files and organize them into a project that defines your target application. µVision2 automatically compiles, assembles, and links your embedded application and provides a single focal point for your development efforts.
LIB51 Library Manager
The LIB51 library manager allows you to create object library from the object files created by the compiler and assembler. Libraries are specially formatted, ordered program collections of object moles that may be used by the linker at a later time. When the linker processes a library, only those object moles in the library that are necessary to create the program are used.
BL51 Linker/Locator
The BL51 linker creates an absolute object mole using the object moles extracted from libraries and those created by the compiler and assembler. An absolute object file or mole contains no relocatable code or data. All code and data reside at fixed memory locations. The absolute object file may be used:
To program an EPROM or other memory devices,
With the µVision2 Debugger for simulation and target debugging,
With an in-circuit emulator for the program testing.
µVision2 Debugger
The µVision2 symbolic, source-level debugger is ideally suited for fast, reliable program debugging. The debugger includes a high-speed simulator that let you simulate an entire 8051 system including on-chip peripherals and external hardware. The attributes of the chip you use are automatically configured when you select the device from the Device Database.
The µVision2 Debugger provides several ways for you to test your programs on
real target hardware:
Install the MON51 Target Monitor on your target system and download your program using the Monitor-51 interface built-in to the µVision2 Debugger.
Use the Advanced GDI interface to attach use the µVision2 Debugger front end with your target system.
Monitor-51
The µVision2 Debugger supports target debugging using Monitor-51. The monitor program resides in the memory of your target hardware and communicates with the µVision2 Debugger using the serial port of the 8051 and a COM port of your PC. With Monitor-51, µVision2 lets you perform source-level, symbolic debugging on your target hardware.
RTX51 Real-Time Operating System
The RTX51 real-time operating system is a multitasking kernel for the 8051 microcontroller family. The RTX51 real-time kernel simplifies the system design, programming, and debugging of complex applications where fast reaction to time critical events is essential. The kernel is fully integrated into the C51 Compiler and is easy to use. Task description tables and operating system consistency are automatically controlled by the BL51 linker/locator.
C51 Optimizing C Cross Compiler
The Keil C51 Cross Compiler is an ANSI C Compiler that was written
specifically to generate fast, compact code for the 8051 microcontroller family.
The C51 Compiler generates object code that matches the efficiency and speed
of assembly programming.
Using a high-level language like C has many advantages over assembly language
programming:
Knowledge of the processor instruction set is not required. Rudimentary knowledge of the memory structure of the 8051 CPU is desirable (but not necessary).
Details like register allocation and addressing of the various memory types and data types is managed by the compiler.
Programs get a formal structure (which is imposed by the C programming language) and can be divided into separate functions. This contributes to source code reusability as well as better overall application structure.
The ability to combine variable selection with specific operations improves program readability.
Keywords and operational functions that more nearly resemble the human thought process may be used.
Programming and program test time is drastically reced.
The C run-time library contains many standard routines such as: formatted output, numeric conversions, and floating-point arithmetic.
Existing program parts can be more easily included into new programs because of molar program construction techniques.
The language C is a very portable language (based on the ANSI standard) that enjoys wide popular support and is easily obtained for most systems.
Existing program investments can be quickly adapted to other processors as needed.
Code Optimizations
The C51 Compiler is an aggressive optimizing compiler that takes numerous steps to ensure that the code generated and output to the object file is the most efficient (smallest and/or fastest) code possible. The compiler analyzes the generated code to proce the most efficient instruction sequences. This ensures that your C program runs as quickly and effectively as possible in the least amount of code space.
The C51 Compiler provides nine different levels of optimizing. Each increasing level includes the optimizations of levels below it. The following is a list of all optimizations currently performed by the C51 Compiler.
General Optimizations
Constant Folding: Constant values occurring in an expression or address calculation are combined as a single constant.
Jump Optimizing: Jumps are inverted or extended to the final target address when the program efficiency is thereby increased.
Dead Code Elimination: Code that cannot be reached (dead code) is removed from the program.
Register Variables: Automatic variables and function arguments are located in registers whenever possible. No data memory space is reserved for these variables.
Parameter Passing Via Registers: A maximum of three function arguments
may be passed in registers.
Global Common Subexpression Elimination: Identical subexpressions or address calculations that occur multiple times in a function are recognized and calculated only once whenever possible.
Common Tail Merging: Common instruction blocks are merged together using jump instructions.
Re-use Common Entry Code: Common instruction sequences are moved in front of a function to rece code size.
Common Block Subroutines: Multiple instruction sequences are packed into subroutines. Instructions are rearranged to maximize the block size.

文献蚂举1:
This project aimed to develop a wireless system to detect and allow only the authorized persons. The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag. The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station, gathers information about the Tag ID and sends this information to the base station. The base station receives, decodes and checks the information available in its Database and Manchester code was used to send those information. The system performed as desired with a 10cm diameter antenna attached to the transponder. The Base Station is built by using the Popular 8051 family Microcontroller. It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.
RFID Reader Mole, are also called as interrogators. They convert radio waves returned from the RFID tag into a form that can be passed on to Controllers, which can make use of it. RFID tags and readers have to be tuned to the same frequency in order to communicate. RFID systems use many different frequencies, but the most common and widely used Reader frequency is 125 KHz.

Choose controller according to your requirements of program memory(flash), RAM, ADC, EEPROM. 16kB of flash is sufficient to implement floodfill algorithm. If you are thinking of implementing floodfill algorithm then 256 bytes are required to store Map of the maze and 512 bytes are required for processing so you need atleast 1kBRAM to implement floodfill. ATmega16,32 and PIC18f452 are some controllerspopularly used in micromouse. If you are thinking of building just a wall follower then simple 8051 based controller likeAT89s52 can also be used. Stepper driving:Please read http://www.triindia.co.in/resources/?p=40 a step by step stepper motor guidefirst. There are two types of motors a) unipolar b) bipolar. Unipolar stepper motors can be used as bipolar steppers so prefer unipolar whilepurchasing stepper. You can use simple ULN2803 IC the circuit can be found in 8051 microcontroller by Mazidi. ULN2803 has eight darlington pair in a single package. It hascurrent carrying capacity of 500mA. so it will get heated up frequently will get damaged.So two ULN2803 can be connected in parallel to fix the problem but this is a chalta haiway of driving stepper.

Stepper Motor Advantages
and Disadvantages
Advantages
1. The rotation angle of the motor is
proportional to the input pulse.
2. The motor has full torque at stand-
still (if the windings are energized)
3. Precise positioning and repeat-
ability of movement since good
stepper motors have an accuracy of
3 – 5% of a step and this error is
non cumulative from one step to
the next.
4. Excellent response to starting/
stopping/reversing.
5. Very reliable since there are no con-
tact brushes in the motor.
Therefore the life of the motor is
simply dependant on the life of the
bearing.
6. The motors response to digital
input pulses provides open-loop
control, making the motor simpler
and less costly to control.
7. It is possible to achieve very low
speed synchronous rotation with a
load that is directly coupled to the
shaft.
8. A wide range of rotational speeds
can be realized as the speed is
proportional to the frequency
