Geomagnetic vehicle inspection device with waterproofness and bearing capability

Abstract

The invention relates to a geomagnetic vehicle inspection device with waterproofness and bearing capability. The geomagnetic vehicle inspection device with waterproofness and bearing capability includes an upper housing, an intermediate housing, a lower housing, a circuit board and a battery, wherein the intermediate housing is sleeved in the lower housing; the intermediate housing is in sealed connection with the upper housing; the lower housing and the upper housing are in sealed connection; the intermediate housing and the upper housing form a sealed accommodating cavity; the circuit boardand the battery are arranged in the accommodating cavity; the circuit board is connected with the inner wall of the upper housing; and the circuit board is electrically connected with the battery. Thegeomagnetic vehicle inspection device with waterproofness and bearing capability has a dual-layer structure, and a glue sleeve sleeves the outer side of the housing, thus preferably improving the waterproofness and the bearing capability of the vehicle inspection device.

Description

technical field [0001] The invention relates to the field of geomagnetic vehicle detectors, in particular to a waterproof and load-bearing geomagnetic vehicle detector. Background technique [0002] In terms of working principle, common vehicle inspection technologies include photoelectric, coil, geomagnetic, ultrasonic, video and infrared detection. The geomagnetic vehicle detector mainly uses the ferromagnetic material contained in the vehicle itself to affect the geomagnetic signal in the area where the vehicle exists, so that the earth's magnetic field lines in the area where the vehicle exists changes, thereby detecting the existence of the vehicle. The vehicle detector takes the motor vehicle as the detection target, mainly detects information such as vehicle passing or parking, and provides enough information for the intelligent traffic control system to make optimal decisions. When the vehicle passes near the sensor, the sensor can sensitively perceive the change of...

Problems solved by technology

Generally, the service life of geomagnetic sensors is 2-3 years. During long-term field use and vehicle rolling, the inside of the sensor is prone to water or moisture, which will affect the detection accuracy of the sensor and even damage the sensor.

At the same time, the car detector is crushed by the car, and the outer shell is prone to deformation. The upper and lower shells of the general single-layer car detector shell are prone to misalignment, and water vapor seeps into the shell, which affects the performance of electronic components.
