Embodiment Construction

[0018] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0019] There are many road vehicle detection technologies, and the road vehicle detection method of the present invention uses geomagnetic type detection, because geomagnetic type detection has many advantages such as not being affected by weather and light (compared to video detection), not affected by occlusion (compared to microwave, radar detection), etc. advantage.

[0020] figure 1 It is a signaling diagram of Embodiment 1 of the road vehicle detection method of the present invention. As shown in the figure, the road vehicle detection method of the present invention specifically includes:

[0021] Step 101, the access point device sends reference time information to the vehicle detection device;

[0022] Step 102, the vehicle detection device receives the reference time information, and performs time synchroniz...

Abstract

The invention relates to a road vehicle detection method, specifically comprising the steps: an access point device sends reference time information to a vehicle detection device; the vehicle detection device receives the reference time information and performs time synchronization according to the reference time information; the vehicle detection device detects electromagnetic field intensity information on a vehicle passing through a road, judges whether a vehicle passes according to the electromagnetic field intensity information, generates vehicle detection information and sends the vehicle detection information to the access point device. The road vehicle detection method further comprises the steps: the access point device sends management information; and a relay device or the vehicle detection device receives the management information and performs configuration processing according to the management information. Accordingly, the road vehicle detection method in the invention can be free from influences of weather and light rays and has high reliability and high precision; in addition, convenient direct communication or relay communication between the vehicle detection device and the access point device is realized, and good communication effect and high processing speed are achieved.

Description

technical field [0001] The invention relates to a method for detecting road vehicles, in particular to a method for detecting road vehicles by using geomagnetic effects. Background technique [0002] With the development of the times, traffic problems have become a big problem that plagues cities. If you want to solve traffic problems, you need to collect vehicle information on roads and intersections, such as collecting information on cars passing by. [0003] Existing road vehicle detection methods can utilize electromagnetic sensing, ultrasonic sensing, radar detection, video detection, and so on. For example, the toroidal coil type vehicle detection device, when the vehicle passes through the toroidal coil buried under the road surface, the coil magnetic field changes, and the detector calculates the information of the vehicle based on this, and thus obtains the flow rate, speed, time occupancy rate and length of the vehicle And other traffic parameters, and upload to t...
