基于单片机的客车超载检测系统设计

Design of passenger car overfreight detection system based on MCU

该文设计了一种可以自动检测客车是否超载的检测系统。该系统以AT89C52单片机为微控制器,利用红外对管传感器、重力传感器、蜂鸣器、继电器和数码管等元件搭建功能电路。当客车超载时,报警电路发出声光报警,并通过继电器电路锁定客车的启动系统。

This paper designs a detection system that can automatically detect whether the passenger car is overfreigh.The system uses the AT89C52 single-chip microcomputer as the microcontroller,and uses the infrared pair tube sensor,gravity sensor,buzzer,relay and digital tube to build functional circuits.When the bus is overfreight,the alarm circuit emits an audible and visual alarm and locks the bus s starting system through the relay circuit.
