毕业设计（论文）长途客车防超载控制系统的设计姓名秦鹏飞学号2014010304002专业班级信息工程14所在学院电子信息学院指导教师陈卉讲师完成时间2018年1月电子科技大学中山学院教务处制发长途客车防超载控制系统的设计摘要在本设计当中主要通过STC89C52单片机的智能化运用，针对客车超载现象设计一款智能化预防控制系统，其中将HX711作为系统的称重芯片来对客车负载进行检测，同时运用了红外对射管F3来作为系统的核心。具体包括主程序控制模块、客车人数检测模块、客车称重子模块、LED显示模块、按键模块、声光报警模块、客车开/关点火模块。系统可以通过按键的方式来设置客车的负载重量最大限制与人数的控制，利用了数码管的显示方式可以监控显示车辆上的人员数量，在客车负载超出额定重量或者人数的时候，激发声光报警器，同时由继电器来控制打火，对汽车进行锁定。当客车人说和重量都符合要求后，报警才会接触，同时解除客车锁定。关键词：客车防超载：SCT89C52:F3红外对射管：HX711Anti-overload control system for intelligentbusAbstractThis paper designs a set of intelligent bus anti overload control system based on single chipmicrocomputer.The core of the system is STC89C52 microcontroller.The core of the wholesystem is F3 infrared to radio tube and HX711 weighing chip.It includes main program controlmodule,bus number detection module,bus weighing baryon module,LED display module,keymodule,acousto-optic alarm module and bus on off ignition module.The adjustment of theupper limit of the bus number and the adjustment of the upper limit of the weight can be set bythe key,and the weight is displayed through the four in one common anode digital tube,and thenumber is displayed through the two in one common anode.When the number of passenger carsor the weight is overloaded or overloaded,the sound and light alarm will be started.At the sametime,the ignition device of the bus is disconnected through the relay and the car is locked.Whenthe bus man says and the weight meets the requirements,the alarm will come into contact andthe lock of the bus is relieved.Keywords:Passenger car overloading;SCT89C52;F3 infrared ray tube;HX711
