Geomagnetic vehicle detector

Abstract

The invention discloses a geomagnetic vehicle detector which comprises a geomagnetic detection module and a wireless charging unit, wherein the geomagnetic detection module comprises a shell; an energy storage unit which is used for supplying power, a first single chip and a geomagnetic sensor and a first wireless transmission module which are connected with the first single chip are arranged in the shell; an input end of the energy storage unit is connected with a receiving circuit and a receiving coil in turn; the wireless charging unit comprises a second single chip, an emitting coil, an emitting circuit and a timer; an output end of the timer is connected with the second single chip; the output end of the second single chip is connected with the emitting coil through the emitting circuit. The geomagnetic vehicle detector has a simple structure and the operation of frequently replacing the battery in the manner of breaking the soil and taking out the device is not required, so that the maintenance cost is greatly reduced and the damage to the pavement is reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a geomagnetic vehicle detector. Background technique [0002] With the rapid development of urban construction, intelligent transportation has become an inevitable trend of urban traffic management, which can effectively alleviate traffic congestion and improve the efficiency of transportation and management. A good road traffic information collection method is the cornerstone of effectively realizing intelligent transportation. At present, there are many products on the market for road traffic information collection, mainly including: ground induction coils, cameras, geomagnetism, etc., and they all have their own advantages and disadvantages. Due to its own nature, the vehicle detector based on the ground induction coil will definitely cause great damage to the road surface. The vehicle detector based on the geomagnetism is generally powered by a...

Problems solved by technology

Due to its own nature, the vehicle detector based on the ground induction coil will definitely cause great damage to the road surface. The vehicle detector based on the geomagnetism is generally powered by a battery. When the battery is exhausted, the device can only be ground. Take it out from the ground, replace the battery or replace it as a whole, and reinstall it. Due to the limited battery life, it needs to be replaced and maintained regularly, which will also cause damage to the road surface.
