Embodiment Construction

[0024] as attached Figures 1 to 3 As shown, the system involved in the present invention consists of a speed limit signal transmitting device 1 installed on the road, a speed measuring device 2 placed on the vehicle, and a process of reading and related processing of data such as speed at the toll gate of the road entrance and exit. The device 3 constitutes.

[0025] The signal transmitting device 1 is set at the speed limit prompt at the entrance of the expressway and the prompt position of the highway speed limit change; the device can continuously or intermittently send the speed limit value signal to a certain range around a certain range; the speed limit value signal sent Including car models and corresponding speed limit values. According to the one-way road width of the expressway; the signal coverage radius of the signal transmitter 1 is set at 30-50 meters to ensure that all lanes are covered; however, it will not cause too much signal interference to other surround...

Abstract

The invention relates to the technical field of vehicle speed monitoring, in particular to a freeway overspeed monitoring method. The method comprises the following steps: speed-limiting signal transmission is realized in such a way that a signal transmitting device arranged at the speed-limiting and road speed-limiting variation prompt position at the entry of a freeway sends a speed-limiting signal around to a certain range; speed-limiting signal receiving is realized in such a way that the speed-limiting signal can be received when a vehicle equipped with a speed measuring device runs into the signal coverage range; vehicle speed measurement is realized in such a way that the speed measuring device measures or reads the running speed of the vehicle according to the received GPS (Global Positioning System) and other satellite positioning signals; overspeed judgment is realized in such a way that the speed measuring device compares the vehicle speed and the limiting speed and storing the speed exceeding the speed-limiting value in a memory unit; and overspeed information reading and processing is realized in such a way that a processing device reads the overspeed information in the memory unit and tells the relevant overspeed punishment to the vehicle. The method provided by the invention achieves gapless freeway speed measurement and can be extensively used for freeway speed measurement and monitoring.

Description

technical field [0001] The invention relates to the technical field of vehicle speed monitoring, in particular to an expressway overspeed monitoring method. Background technique [0002] Existing vehicle speed measurement methods mainly include radar, laser, and ground-sensing coil speed measurement; the aforementioned methods all have defects such as complex structure, high cost, and inconvenient installation, use, and maintenance. For this reason, Chinese Invention Patent No. 200610021463.1 discloses a highway radio frequency vehicle speed monitoring and management system. The system is composed of a signal machine fixed on the road, a wireless license plate and a computer management system; in the scheme disclosed by the invention, since the signal machine is fixedly set on the expressway, the speed measurement can only be realized at the position where the signal machine is installed. Therefore, fail to highway, especially expressway realizes the full speed monitoring w...
