Intelligent entrance guard control system with wireless ad hoc network function and control method thereof

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...

AI Technical Summary

Problems solved by technology

[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 adopts half-duplex communication, which has low communication efficiency, poor anti-interference ability, and poor load capacity. If the number of access controllers is large, additional repeaters are required for relaying

[0007] 3) Poor security performance. RS485 uses a pair of differential lines for communication. If someone accesses the RS485 network, it can steal the authorization information of the access controller, etc.

[0008] 2. The card reader has no security authentication function

[0012] 1) The security of the Windows desktop system is poor, and it is vulnerable to various computer viruses such as worms and Trojan horses. However, the access control system is generally located in a closed private network, and its virus database cannot be updated even if anti-virus software is installed. The ability is also very poor

Moreover, due to the architecture of the Windows operating system, its stability is difficult to guarantee, which greatly increases the difficulty of maintenance for administrators.

[0013] 2) The function of the client side of the access control system is relatively simple, and it only needs to be able to connect to the Internet to upload and send data. Using a PC will waste resources on the one hand, and undoubtedly increase the cost of the system on the other hand.
