Design For Overweight Monitoring System Of Freight Car

With the national economy development,science and technology is becoming more and more developed,people's living standards improve significantly,scope of activities is becoming more and more broad,way to travel is becoming more and more diversified.However,modern transportation network has brought people convenience,also brings the problem of traffic safety hidden trouble.According t the national bureau of statistics: in 2014,the national 196812 traffic accidents,killing 58523 people,211882 people were injured.Overloaded vehicles increases on the shield also,each year from national highway cargo vehicle overloading caused the loss of more than 30 billion yuan,also is a big loss to the country's fiscal.The cause of the accident are:whether the state of the driving personnel,technology,overload,pedestrian traffic behavior,the road smooth and road design,etc.These are causing a traffic accident of subject and object.According to statistics,trucks more than 80% in the road traffic accidents are caused by overload transportation.This design from the regulatory means to start,out of the vehicle cargo safety research,through technical means to achieve the intervention to reduce the incidence of traffic accidents.In this paper,the truck overweight control system,systematic exposition of the generation and development of large trucks overloaded,the principle and technology of monitoring large trucks overloaded system and need to to bear the weight of a large truck transport of uniform load detection can be determined is overweight trucks and truck overweight provide alarm behavior.STC89C52 MCU is for the design of the central processing unit(CPU)and weighing sensor WP10 will weight signal is converted into a voltage signal and a / D conversion chip TLC0838 will again be converted into digital signals,you can easily draw the trucks of the actual weight and the actual weight of will is transmitted to PC by RS485 interface,then the system will automatically measured weight and weight setting were compared,we can easily judge whether overweight trucks,if overweight will initiate the alerts also shows its weight in excess...
