Problems solved by technology
[0002] At present, intelligent traffic signal controllers in the world generally use three mathematical models of TRANSYT, SCOOT, and SCATS to simulate the scene conditions, but these three conditions are far from the actual traffic environment in my country and do not conform to the national conditions.
In addition, for the green wave and special service lines, the first is to rely on the traffic police to maintain order, and the second is to rely on the command center to control the on-site signal conversion after receiving instructions from the scene, which leads to slow response and affects traffic order.

The invention relates to a wireless geomagnetic vehicle detector comprising a detecting unit and a receiving unit. The detecting unit reads information and transmits the information into the receiving unit. The detecting unit is buried underground and is in the shape of a cylindrical knob; the detecting unit internally comprises a sensor, an AD (analog-digital) converter and a signal transmitter. The wireless geomagnetic vehicle detector is simple in structure, capable of running stably, convenient to install, convenient to carry, wide in transmitting range and applicable to the range of vehicle speed 0-200m / h and has detection radius of 0-2m.
Description
technical field [0001] The invention relates to a vehicle detector, in particular to a wireless geomagnetic vehicle detector. Background technique [0002] At present, intelligent traffic signal controllers in the world generally use TRANSYT, SCOOT, and SCATS three mathematical models to simulate the scene conditions, but these three conditions are far from the actual traffic environment in my country and do not conform to the national conditions. In addition, for the green wave and special service lines, the first is to rely on the traffic police to maintain order, and the second is to rely on the command center to control the on-site signal conversion after receiving instructions from the scene, which leads to slow response and affects traffic order. Contents of the invention [0003] In order to solve the above problems, the present invention provides a wireless geomagnetic vehicle detector with simple structure, stable operation, convenient installation, portability an...
