Parking lot entrance/exit structure used for mounting ground induction coil

Abstract

The invention discloses a parking lot entrance / exit structure used for mounting a ground induction coil. The parking lot entrance / exit structure used for mounting the ground induction coil comprises a square coil groove which is formed in the ground. A step surface which stretches out towards the two sides is arranged on the upper portion of the coil groove. The bottom side of the step surface inclines downwards in the direction away from the coil groove. Rubber pads are bonded to the bottom side and the lateral sides of the step surface correspondingly. A drainage channel is formed in the lowest position of the step surface, and drainage holes are formed in the rubber pad located over the drainage channel. The parking lot entrance / exit structure used for mounting the ground induction coil further comprises a prefabricated concrete frame arranged on the step surface. The bottom of the prefabricated concrete frame is matched with the step surface. Concave holes are formed in the four edges of the surface of the prefabricated concrete frame correspondingly and are each of an inverted-T-shaped structure. By the adoption of the parking lot entrance / exit structure used for mounting the ground induction coil, the problem that in the prior art, the buried ground induction coil cannot be inspected or replaced conveniently is solved, and the purposes of inspecting or replacing the ground induction coil conveniently, and reducing the construction cost are achieved.

Description

technical field [0001] The invention relates to the field of parking lot engineering, in particular to a parking lot entrance and exit structure for installing ground induction coils. Background technique [0002] The ground sense coil is part of the oscillating circuit. The oscillating circuit is composed of it and the capacitor. The principle is that the oscillating signal is stable and reliable. The oscillating signal is sent to the frequency measurement circuit composed of the single-chip microcomputer through conversion, and the single-chip microcomputer can measure the frequency of the oscillator. When a large metal object such as a car passes by, the oscillation frequency changes due to the change of the space medium (the oscillation frequency increases when there is a metal object), and this change is used as a confirmation signal that the car passes through the "ground induction coil". The entrance and exit of the parking lot is used as a sensing device to monitor ...
