最近一段时期,部分地区连续发生多起超限超载车辆压垮桥梁、造成人员伤亡的安全事故。于是,我们决定开发一种由压力传感器、集成运放、电压比较器、稳压芯片、指示灯等组成的货车超载监控装置,以自检方式监控货车是否超载。本装置以绿、黄、红灯显示货车载重状况。正常载重“绿”灯亮,货车可以启动运行;货车超载“红”灯亮,蜂鸣器响,货车电源立即断开,不能启动运行。黄灯为预警灯,装货时不得使黄灯亮。这样,从第一时间,第一地点监控货车超载,既节约国家资源,又保护道路桥梁和人民生命安全。货车超载监控装置简单、科
In recent days, several consecutive accidents in some areas have resulted in accidents such as overloading of overloaded vehicles to crush bridges and casualties. As a result, we decided to develop a truck overload monitoring device consisting of a pressure sensor, an integrated operational amplifier, a voltage comparator, a voltage regulator chip, and a pilot lamp to monitor whether the truck is overloaded with a self-test method. The device to green, yellow, red light truck load status. Normal load “green” light, the truck can start running; truck overload “red” light, buzzer sound, truck power immediately disconnected, can not start running. Yellow light as warning light, loading yellow light can not be bright. In this way, from the first time, the first place to monitor the truck overloading, not only save the country's resources, but also protect the road bridges and people's lives and safety. Truck overload monitoring device is simple, Branch
