High-reliability machine room intelligent entrance guard opening method and opening system

Abstract

The invention discloses a high-reliability machine room intelligent entrance guard opening method and an opening system. The method comprises the following steps: a user logs into a mobile phone client, and a central server generates a pseudo-random code and a time stamp and sends to the mobile phone client; the user reaches an authorized station and constructs wireless data connection; an entrance guard controller is provided with a pseudo-random code generation mechanism which is the same as that of the central server and changes with the clock, the mobile phone client sends the pseudo-random code and the time stamp, and the entrance guard controller adjusts the pseudo-random code according to the time stamp and compares the pseudo-random code with the pseudo-random code of the entrance guard controller. A mobile phone acquires the pseudo-random code and the time stamp from the central server, and the entrance guard controller adjusts the pseudo-random code according to the time stamp and compares with the pseudo-random code sent by the mobile phone, and the central server does not need to communicate with the entrance guard controller, so that the cost is reduced, and the security is improved; by pseudo-random code comparison, the reliability is improved.

Description

technical field [0001] The invention relates to an access control opening method and system, in particular to a reliable computer room intelligent access control opening method and an opening system. Background technique [0002] The traditional communication room access control system mainly adopts the following three technical solutions: [0003] One is the intelligent access control system based on IC / ID card and dynamic environment monitoring system; [0004] The second is an intelligent access control system based on SMS request and dynamic environment monitoring system; [0005] The third is an independent access control system based on SMS transmission scheme. [0006] The biggest disadvantage of the first solution is: when the dynamic environment monitoring system is interrupted, the monitoring center cannot manage the increase or decrease of the authority of the access control controller in the computer room, and the real-time information of the personnel entering...

AI Technical Summary

Problems solved by technology

[0006] The biggest disadvantage of the first solution is: when the dynamic environment monitoring system is interrupted, the monitoring center cannot manage the increase or decrease of the authority of the access control controller in the computer room, and the real-time information of the personnel entering and leaving the computer room cannot be fed back to the monitoring center server;

[0007] The disadvantage of the second type of access control system is that the reliability of remote door opening is not high, and when the dynamic ring monitoring system is interrupted, the door cannot be remotely opened by SMS;

[0008] The disadvantage of the third type of access control system is that the reliability of remote door opening depends on the reliability of the mobile network and the SMS network. When the SMS network is congested and the mobile network service terminal in the computer room is not in the service area, the SMS cannot be used to open the door.
