Entrance guard logic control system and control method thereof

Abstract

The invention discloses an entrance guard logic control system and a control method thereof. The method comprises the steps that according to the door opening logic requirement of an actual door lock,a logic configuration unit conducts corresponding logic configuration on an MCU, a first controller sends a first control signal, and a second controller sends a second control signal; the detectionunit collects a first control signal and a second control signal, the MCU judges whether the state is abnormal or not according to the logic configuration condition of the logic configuration unit, and when it is judged that the state of the first control signal or the state of the second control signal is abnormal, a signal corresponding to the abnormal state is blocked and shielded. The logic configuration unit can carry out logic configuration on the MCU according to requirements, blocks and shields signals in an abnormal state so as to prevent the signals in the abnormal state from influencing accesses of other signals in the normal state, so that the reliability of door lock control is effectively improved, and the logic control requirement in an actual application scene is better met.

Description

technical field [0001] The invention relates to the field of access control for prisons and institutions on duty, in particular to an access control logic control system and a control method thereof. Background technique [0002] In prison sentry posts, there are often strict requirements on the access control system. Generally speaking, personnel need to go through a strict verification process when entering and leaving, and then the back-end duty center confirms that they are correct before they are allowed to pass. [0003] In the existing access control method, multiple door lock control signals are coupled together for control during the door lock control process. When using this control method to control the door lock, when one of the control signals is abnormal, the abnormal signal is connected to the door When locking the control module, it is easy to cause the failure of the door lock control module, the reliability is low, and the number of multiple door lock contr...

[0003] In the existing access control method, multiple door lock control signals are coupled together for control during the door lock control process. When using this control method to control the door lock, when one of the control signals is abnormal, the abnormal signal is connected to the door When locking the control module, it is easy to cause the failure of the door lock control module, the reliability is low, and the number of multiple door lock control signals will be limited due to signal attenuation and series connection restrictions, which cannot meet the actual logic control requirements and realize multiple Access control signal management, low security level
