Abstract

The invention discloses an entrance-exit control circuit comprises a main control board circuit. The main control board circuit comprises a network interaction control circuit having a main control chip, a network transformer circuit, a network protection circuit, an RJ45 interface circuit and a main control chip power source circuit, the network interaction control circuit is electrically connected with the network transformer circuit which is electrically connected with the network protection circuit, and the network protection circuit is electrically connected with the RJ45 interface circuit; the network interaction control circuit further comprises an internal voltage compensation circuit, a clock circuit, a working indication circuit, a filter circuit, a resetting circuit and an impedance matching circuit which are electrically connected with the main control chip, and the network transformer circuit is connected with the impedance matching circuit. The main control chip is made to directly control a network switchboard chip, multiple RJ45 interfaces are provided, and network switchboard equipment in the middle is removed, so that cost is lowered, assembly space is reduced, wiring is simple, convenience is brought to mounting and maintaining, and overall performance of equipment is improved.

Description

technical field [0001] The invention mainly relates to an entrance and exit control circuit. Background technique [0002] In the entrance and exit control equipment, in order to realize the safety management and control of people or vehicles, it is necessary to adopt multiple methods for management and control, and a network of various equipment is jointly formed. In the field of parking lot control, vehicle control needs to adopt methods such as license plate recognition or card detection, and assist network intercom and video surveillance, etc., and all devices are connected through TCP / IP. The current method is to add a network switch to the control equipment, which increases the cost, increases the assembly space, is not conducive to installation, and increases the point of failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an entrance and exit control circuit in order to overcome the above-mentioned ...
