Abstract

A mini buried under ground vehicle detector comprises metal sensing detection coil and its oscillator unit, vehicle geomagnetic image detection unit, demodulation / commutation circuit unit, signal process / logic process unit, signal transition / transmission interface unit that can also link sub-detector, power and shell. This invention can detect vehicle flowrate, road occupancy rate, speed, stopping time and temperature of road surface; widely used to monitor for traffic and park, management and command system; with low cost, little volume, modularization, high reliability; use total encapsulated out shell, buried under road surface; convenient and speed to assembly, and needs no maintenance; it can be also used to security alarm and monitor system.

Description

technical field [0001] The invention relates to a vehicle detection device, in particular to a miniature buried vehicle detector. The device can be used in urban or highway traffic command management systems and vehicle static management systems. It is suitable for traffic light control system, electronic police camera system, vehicle toll station system, vehicle access control system, parking lot management system and road network traffic monitoring and management system, etc. Background technique [0002] With the development of the economy and the improvement of people's living standards, cars are getting closer and closer to people's lives, urban traffic and highway traffic congestion occur from time to time, especially the traffic conditions in large and medium-sized cities have become the focus of the government and the public One of the focal issues is that a lot of manpower, material resources, and funds are invested in road reconstruction and road construction. Even...
