Embodiment Construction

[0023] as attached Figures 1 to 3 As shown, the system of 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 processing device 3 that reads data such as speed and performs related processing at the toll gate of the road entrance and exit. constitute.

[0024] 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 vehicle 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 surroundi...

Abstract

The invention relates to the technical field of vehicle speed monitoring, in particular to a freeway overspeed monitoring system. The freeway overspeed monitoring system consists of a speed-limiting signal transmitting device mounted at the speed-limiting and road speed-limiting variation prompt position at the entry of a road, a speed measuring device arranged on a vehicle and a processing device arranged at a passageway toll house on the road and used for reading and performing other treatment to the speed and other data, wherein the speed measuring device receives signals sent by the signal transmitting device, then compares the received signals with measured vehicle running speed and stores the speed exceeding the speed-limiting value and related information in a memory unit; the information stored in the memory unit of the speed measuring device is read when the vehicle runs away from the toll house; and the processing device respectively calculates the toll sum and the overspeed information according to the information, and tells the road toll and the overspeed punishment situation to the vehicle. The freeway overspeed monitoring system can achieve 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 system. 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...
