Description

Technical Field

[0001] The utility model relates to the technical field of access control devices, and in particular to an access control device based on power line carrier communication technology. Background Art

[0002] Access control is mainly used to prevent others from illegally entering a certain area, and the device that controls the opening or closing of the access control is called an access control device.

[0003] The access control system usually uses wired or wireless communication technology to transmit management control signals to control the opening and closing of the access control electromagnetic lock, such as RS485 bus, TCP / IP, Wiegand protocol, etc. Using magnetic cards, passwords, fingerprints or face recognition as keys, the key information is read by a card reader, a password device, an exit button, etc., and transmitted to the corresponding local access control controller through the RS485 bus or TCP / IP. The access control controller receives the key information and compares it with the stored key information. If the comparison is consistent, the local controller will send an unlocking signal to the electromagnetic lock to control the electromagnetic lock to open.

[0004] Since most of the current signal transmission uses RS485 bus or TCP / IP. The RS485 bus communication method requires additional wiring during deployment and the transmission distance cannot exceed 1000m. The networking is not flexible and it is complicated to add or delete points. RS485 communication cannot carry video information and cannot use face recognition to unlock the door. The TCP / IP method uses star wiring, and a large number of cables need to be laid horizontally. The data transmission distance does not exceed 100m. The part exceeding the distance needs to add switches and lines to ensure stable communication. Both methods will generate very high deployment and installation costs, as well as subsequent operation and maintenance costs. In addition, the access control device is installed through a circuit board, and when the circuit board is installed, it is easy to affect heat dissipation. When it is installed through a sleeve with a thread inside, the sleeve is easily damaged, resulting in the inability to install the mounting seat, and the entire device is directly scrapped. For this reason, we propose an access control device based on power carrier communication technology. Utility Model Content
