驾驶员超速驾驶是导致交通事故的主要原因，给人们的生命和财产安全造成极人的损尖。当前，交通管理部分主要采取交警定点测速、巡逻车流动测速、定地点电子测速等方式对驾驶员超速行为进行检测与处罚，这些测速方式，存在一定的局限性，在一些没有监控设备或交警值勤的路段，无法对超速乍辆进行监测。因此，设计可以全程对驾驶员超速列驶进行白动监测和控制的系统，不仅能够实时对驾驶员超速行为进行警示，还可以直接控制驾驶人员当前的车速，对减少交通事故和改善交通执法具有重要的意义。设计采用单片机进行设计，通过霍尔传感器对的当前车轮的驾驶速度进行实时检测，检测到当前车辆的速度大于设置的最大值的10%以内时，进行声光报警；当超过30s分钟后，速度还超过设置最大值，强制调整测速，管理人员可以根据当前车辆的行驶情况进行车速的调节，当前检测的车速通过液晶显示屏进行显示。实验表明该系统能实现驾驶员超速行驶的无线自动监测和控制。

Drivers speeding is the main cause of traffic accidents, to people’s life and property safety caused extreme damage. At present, the traffic management part mainly adopts the traffic police fixed-point speed measurement, patrol car flow speed measurement, location electronic speed measurement and other ways to detect and punish drivers speeding behavior, these speed measurement methods, there are certain limitations, in some road without monitoring equipment or traffic police on duty, unable to monitor the speeding. Therefore, the design of a system that can monitor and control the driver’s overspeed in the whole process can not only warn the driver’s overspeed behavior in real time, but also directly control the driver’s current speed, which is of great significance for reducing traffic accidents and improving traffic law enforcement. Design using single chip microcomputer design, through the Hall sensor on the current wheel driving speed for real-time detection, detected the current vehicle speed is greater than the maximum set within 10%, sound and light alarm; When more than 30 minutes, the speed also exceeds the maximum set, forced to adjust the speed measurement, management personnel can adjust the speed according to the current vehicle driving situation, the speed of the current detection through the LCD display. Experiments show that the system can realize wireless automatic monitoring and control of overspeed driving.
