[Technical field to which the invention belongs] The present invention relates to a vehicle overspeed warning system and an ancient road speed limit measurement method ', and particularly relates to a combination of communication technology to determine whether a vehicle is overspeeding or not. [Previous Technology] Today there are a large number of vehicles and traffic accidents are frequent. The main reason for traffic jams is that the vehicle speed is too fast. Therefore, in order to reduce the occurrence of traffic accidents, roads are usually set with speed limits. In order to further provide effective deterrence for drivers to drive too fast, government agencies = set up speeding cameras near the roads. When the speed limit of the road section is restricted, it will be photographed by the speeding camera, and the second person Wan Jingren will receive a penalty for speeding. ...,

Provides the use of the system to determine whether the sound of the car sounds invalid or the vehicle speed is a speed photo. The speed limit is f 1J. The current detection is beneficial: '4 %% \ Sub-line messages are up and middle. Measured by reported debt, speeding, and

The upper and upper direction of the upper and lower direction is to know that the driving is accurate and uniform, both helmets ^ rf, and N times are photographed by the speed camera. Is there a speed limit? It is easy to detect the speed, and the device will be used by the sound method. The overspeed decelerating indicator installed in the device is used to determine the function of the destination vehicle based on the overspeed sound information from the outside world, and the photos are launched for loading. The detection signal is used to inform the driver that the vehicle is overspeeding. The speeding signal is set by the speeding vehicle. However, the speeding signal is used to cause the vehicle to stop. No matter whether there is a super device in front of the driver, the device will be installed. car
