Abstract

The invention provides a novel entrance guard system which is low in cost and is convenient, flexible and reliable. The entrance guard system includes a door device, a plurality of indoor devices, and electric wires. The door device is connected to the indoor devices through the electric wires. The door device is installed on a door and the indoor devices are plugged in electric wire sockets in a living room and a kitchen. The door device includes a single-chip microcomputer, a voice call circuit, an encoding / decoding circuit, an electric door lock, a modulation-demodulation circuit, a transformer coupling circuit, a microphone and buttons. The microphone and the buttons are installed outdoor; the single-chip microcomputer, the voice call circuit, the encoding / decoding circuit, the electric door lock, the modulation-demodulation circuit and the transformer coupling circuit are installed indoor; the single-chip microcomputer is respectively connected to the buttons, the voice call circuit, the encoding / decoding circuit and the electric door lock; the microphone is connected to the voice call circuit; the voice call circuit is connected to the modulation-demodulation circuit; the modulation-demodulation circuit is connected to the transformer coupling circuit and is mutually connected to the encoding / decoding circuit.

Description

technical field [0001] The invention belongs to the technical field of residential safety management in urban quarters, and in particular relates to a novel access control system. Background technique [0002] At present, there are two communication methods adopted by the access control system: (1) Dedicated line: every household or even every room is laid with communication lines. The advantage is strong anti-interference ability and excellent performance; the disadvantage is that the wiring affects the indoor appearance, large amount of engineering, inconvenient to move, and high cost. (2) Wireless: The wireless data transmission module establishes a dedicated wireless data transmission mode, which saves manpower and material resources, and is flexible and convenient. The disadvantage is that in the short-distance data communication system, the cost of the wireless communication method is not lower than that of the wired method, and the anti-interference ability is poor. ...
