Abstract

The invention discloses an intelligent entrance guard control system with a wireless ad hoc network function and a control method thereof, which achieve the wireless ad hoc network function and remove difficulty in project wire arrangement. A safety identification module is added in a card reader to improve system safety. An entrance guard system management terminal applies an embedded gateway to manage every entrance guard controller on one hand and exchange information with an entrance guard management server on the other hand. The system adopts the mode of combination of the B / S structure and the C / S structure and is formed by a center server, branch center servers and an intelligent entrance guard controller. A center server database is interlinked with each branch center server database, and the branch center servers start ZigBee protocol stack and conduct data communication with the intelligent entrance guard controller through a ZigBee and / or transmission control protocol (TCP) / Internet protocol (IP) interface. The entrance guard controller is connected with a card reader connected with an encryption module. The swiping card record is uploaded by the intelligent entrance guard controller to corresponding branch center servers and then to the center server.

Description

technical field

[0001] The invention relates to an intelligent access control system and method with wireless ad hoc network function. Background technique

[0002] The traditional access control system is composed of access controller, card reader and access control system management software. The following problems generally exist:

[0003] 1. Access controllers generally use a single RS485 interface

[0004] At present, access controllers on the domestic market generally use RS485 interface for networking. This method has the following common problems:

[0005] 1) The access controller uses RS485 for networking, which requires a lot of engineering wiring, and the construction is also difficult.

[0006] 2) RS485 uses half-duplex communication, which has low communication efficiency, poor anti-interference ability, and poor load capacity. If there are a large number of access controllers, additional repeaters are required for relaying.

[0007] 3) Poor security perform...
