摘要:

介绍了以单片机AT89S52为控制核心的智能简易车辆系统设计方案。系统根据角度传感器检测的信号,控制小车在跷跷板上做相应运动,其中采用角度传感器感应板面水平角是否为零,确保小车达到平衡。同时采用反射式光电传感器感应板面引导线,保证小车不脱离轨道,并指引小车在规定区域内顺利爬上板面。系统显示装置采用RT1602液晶显示器,能够实时显示行距、时间;小车动力源采用步进电机,并用STA475集成晶体管芯片构成的桥式电路对其驱动,电源直接由12 V蓄电池供电,单片机根据各模块检测的信号作出判断,保证小车正常行动。

Abstract:

This paper introduces the design of a simple intelligent vehicle system controlled by SCM AT89S52.The system detects the car using the signal angle sensor and controls the car to do corresponding movement on the seesaw.The board level angle of the angle sensor is zero so as to keep the car in balance,and the induction surface reflection type photoelectric sensor guide line is adopted to keep the car right on the track and guide the car in a specified region to successfully climb up on the board.RT1602 liquid crystal display system is used as system display to show the row spacing,and time.A stepping motor power supply directly powered by 12 V batteries is used as the power source,with a bridge circuit composed of STA475 transistors integrated chip to drive.The MCU ensures the normal operation of the car according to the signals of each module.

Key words: monolithic integrated circuit AT89S52;simple intelligent vehicle system;angle sensor;Step by steps the electrical machinery;RT1602 liquid crystal display
