基于单片机的车辆超载系统

AbstractIn today's society,a large part of major traffic accidents are caused byoverload.This paper is a vehicle overload system designed to reduce thesafety hazards caused by traffic accidents and the safety of people's lives andproperty.The overload system needs to be able to judge the overload of thevehicle.When the vehicle finds an overload violation,the system sends analarm and displays the weight on the LED screen.If it is a passenger car,itcan calculate the number of people in the vehicle.The design is based on the STC89C52 microcontroller as the core of thesystem processing.There are two parts,which are hardware design andsoftware design.The hardware part uses infrared sensors and directiondetection circuits to record and evaluate and enter the system.Passengers geton and off.The processed data is sent to the LED display through themicrocontroller system.The sound and light alarm device circuit iscomposed of a buzzer and a light-emitting diode,and the relay is used toblock the bus starting device.The software part is programmed in assemblylanguage and has a modular structure.After debugging the system,it canbetter complete the early warning and early warning of vehicle overload,andcontrol overload.Keywords:intelligent overload,single chip microcomputer,convenience
