Embodiment Construction

[0011] There are three major modules in the control program, communication interface module, condition acquisition module, and action execution module. The communication interface module is mainly responsible for communicating with the main control program and analyzing various commands issued by the main control. The condition acquisition module is mainly responsible for various logic conditions in the gate operation, and these conditions include all possible situations in the gate operation. The main basis for selecting the condition is that the condition has a direct impact on the opening and closing of the turnstile door. For example, in the case of normal traffic, passengers intrude from the opposite direction. In this case, the door must be closed as soon as possible, so The condition of intruding in the opposite direction is a very important condition. For example, when the gate receives the information that a passenger has successfully swiped the card, the gate door sh...

Abstract

The invention discloses a gate access control algorithm. The invention proposes a logic table-based drive control algorithm, which includes: updating the state table according to the main control program command and the collected sensor occlusion in the gate channel , compared with the preset logic control table in the system to determine the opening and closing status of the turnstile door. The beneficial technical effects of the present invention are: simplifying the complex logic judgment of the program, and enhancing the scalability of the program at the same time, that is, if there is a new logic condition to be added, only a new logic table condition needs to be added, and a logic judgment is also added at the same time subroutine.

Description

technical field [0001] The invention relates to a gate passage control algorithm, in particular to a passage control algorithm driven by a logic table. Background technique [0002] In the existing technology, gate access control algorithms mainly include gait recognition algorithm of motion mode and algorithm based on rule base control. Both algorithms have complex logic control, difficult modeling, high hardware requirements, and relatively real-time performance. Bad and bad. Contents of the invention [0003] The present invention proposes a logic table-based driving control algorithm, which includes: updating the state table according to the main control program command and the collected sensor occlusion in the gate channel, and comparing it with the preset logic control table in the system , to determine the opening and closing status of the turnstile door. [0004] The update of the state table can be realized from two aspects: one is to accept the main control pro...
