Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] The present invention proposes a wireless vehicle detection system, such as figure 1 As shown, it includes: detectors, receivers, repeaters, and intelligent data processors, using detectors buried in the road to detect the existence and passage of vehicles, and transmitting the detection data to nearby receivers in real time through low-power radio technology. The receiver in turn passes the data to an intelligent data processor.

Abstract

The invention provides a wireless vehicle detection system. The wireless vehicle detection system comprises a detector which is internally provided with a wireless magnetic resistance sensor, a receiver, a relay and an intelligent data processor, wherein the detector is arranged in a hole bored at a designated position of a lane, the detector and a traffic direction are consistent, a sealant is utilized to seal the hole, vehicle existence and the vehicle passing information are detected, the detection data is sent by the detector, the receiver is used for receiving the data sent by the detector and is further used for processing the received data and transmitting the processed data, the relay is used for supporting the detector and the receiver mounted beyond a wireless access point scope of the receiver to carry out bidirectional transmission, and the intelligent data processor is used for receiving the detection data from the receiver and processing and storing the relevant traffic statistics data. According to the wireless vehicle detection system, pipeline layout is not necessary, mounting construction is simple and rapid, influence on a road surface is small, a road base is not influenced, the road surface occupation time is short, maintenance is simple and convenient, detection precision is high, the wireless vehicle detection system is stable and reliable, and the wireless vehicle detection system is not influenced by the natural environment and climates such as rain, snow, mist or night factors.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a wireless vehicle detection system. Background technique [0002] With the increase of the number of motor vehicles in our country, real-time traffic information is becoming more and more important for urban management. For traffic information release and flow survey, road vehicle detection is essential. The existing road section vehicle detection mainly has the following methods: [0003] (1) Ground sense coil detection [0004] The installation process of the ground sensing coil needs to cut the road surface, which seriously damages the road surface and affects the service life of the road; each coil needs to be threaded, the construction speed is slow, and the road takes a long time; in addition, special road sections such as bridges and tunnels are difficult to install. [0005] Deformation or unevenness of the road surface caused by heavy vehicles, road maintenance, hi...
