Abstract

The invention discloses a multi-interface Wiegand communication expansion board with configurable input and output, and relates to the field of security and protection equipment expansion. The Wiegand input / output interface unit I and the Wiegand input / output interface unit are configured as Wiegand input interfaces or Wiegand output interfaces. And the Wiegand input interface unit I and the Wiegand input interface unit II output the received Wiegand data through any one of the Wiegand output interface unit, the serial bus RS485 interface unit or the serial bus RS232 interface unit. And the Wiegand output interface unit outputs Wiegand data input from the Wiegand input / output interface unit, the Wiegand input / output interface unit, the Wiegand input interface unit, the serial bus RS485 interface unit and the serial bus RS232 interface unit. According to the invention, the flexible expansion of the access controller interface is realized, the expansibility and compatibility of the access controller are greatly improved, and more equipment can be quickly expanded as little as possible on the basis of the existing system.

Description

technical field [0001] The invention relates to the expansion field of security equipment, in particular to a multi-interface, input and output configurable Wiegand communication expansion board. Background technique [0002] In the prior art, the number of input interfaces of the access control controller is usually fixed, and to increase the input interface of the device, it is necessary to modify the hardware of the controller. With the increase of applications, there will be more and more devices connected to the access control system, such as face recognition devices, QR code recognition devices, etc. The limit on the number of input interfaces of the access control controller will not meet the needs of adding more devices . [0003] With the development of technology, in the existing access control equipment products, the communication interface of the equipment is no longer a single Wiegand interface, and more and more devices prefer to use interfaces that can commun...
