【正文】 tasseled set when shipped with project of AT89C52 single chip microputer external interruption. In order to recognize a plete key signal, must for each coding pulse width were measured with discriminate receives the pulse is o still 1. the microcontroller timer/counter to measuring pulse width. Timer/counter except points than can be set, from except 2 to except 2048, measurable pulse width can reach 500m/s. This paper set except point for 12, namely than 12 points frequency, because the external clock is about 12MH, clock cycle for 1s, so the timer/counter for 1 per timing once s. alarm module design Alarm module core chip 110 IC, can choose application in automobile, motorcycle, alarms, personal riot device, door magnetic alarm device and etc.3. System software designThis system software modular structure, he main program, initial antifuzzy procedures, interrupt subroutines, delay subroutines, buttons pronunciation subroutines, buttons scanning subroutines constitutes. tracing subroutines designTracing module is designed by the left right photoelectric sensor output terminal receiving monolithic respectively, p22 and p23 tube feet, then through the microcontroller programming, produce PWM control signal. Through L 298 control motor speed, let the car to move forward, left turn, turn right and stop driving purpose. avoid barrier of programmingObstacle avoidance module is designed by the infrared reflection sensor module around the output terminal receiving MCU respectively p20 and p21 tube feet, then through the microcontroller programming, produce PWM control signal, through L298 control motor speed, let the car to move forward, left turn, turn right and stop driving purpose. remote subroutines designRemote control module is designed by the infrared sensor 1838 an output terminal of the receiving MZUp32 tube feet, then use allpurpose remote control on the remote control, then let microcontroller decoding, produce PWM control signal, through L298 control motor speed, let the car move forward, left turn, turn right and stop driving purpose.4. SummaryAdopts singlechip, using photoelectric senor and infrared reflection senor was designed as a detection system, can realize automatic homing line to walk, automatic obstacle avoidance, alarm and remote control functions such as intelligent car. This design is the obvious advantage of simple circuit, reliability, low cost, and easy to function of further perfecting and expansion. From 基于單片機(jī)的智能小車(chē)通過(guò)研發(fā)實(shí)現(xiàn)了一種一光電傳感器為敏感元件，以AT89C51單片機(jī)為控制核心的電機(jī)循跡小車(chē)的智能控，該系統(tǒng)還包括直流電機(jī)、L9110芯片和LM324比較器等。 If the right has not been detected light ,then turn correct direction . motor control and driving module design Because use is double drive cars ,this part of the circuit must be able to output of two different voltage values ,respectively to controlling trolley
