ground sense coil, whether as the license plate recognition system can accurately capture opened one of the ways, it need according to the site environment in installation for accurately measuring installation location and length.Ground sense coil is actually an oscillating circuit, it is laid on the ground to create a circular groove, about a meter in diameter, then in the groove into two or three turns of wire, it constitutes the inductance coil of a buried in the earth’s surface, is made up of it and capacitance oscillation circuit, when the vehicle passes, can cause the change of the oscillation frequency, which is as a car after ground sense coil of a signal.
the laid of ground sense coil is affected by environment, so not only should consider when buried area (or circumference) and the size of the number of turns, consider the material of coil, wire high mechanical strength and low temperature aging problem, where certain conditions must also consider naisuanjian corrosion problems, therefore, generally in view of the parking lot of the 1.0 mm above the ground sense coil recommended teflon high temperature more than soft wire.
the laid of the ground sense coil position for license plate recognition capture also has a great influence, from the location of the license plate recognition control machine and the gate position is very important, too close, easy to cause the brake lifting lever slowly, vehicles hit the brake lever, and the distance will affect the recognition effect, so for the laid of ground sense coil must find a professional manufacturer of construction or parking equipment manufacturers.
so ground sense coil as an important equipment used to manage the vehicles in the parking lot, 24 hours a day uninterrupted operation, its stability directly affect the operation of the parking lot, parking lot system construction in strict accordance with the requirements of installation, it is also a nip in the bud.
