Automatic gate control circuit

Abstract

The invention provides an automatic gate control circuit, which comprises a master control module, a motor module, a light curtain identification module, a Uart communication module and a Can communication module; the master control module is used for starting and initializing a gate system, executing passage logic control and communicating with an upper computer, and comprises a master controller and a slave controller; the motor module carries out control on the operation of a gate-driving motor; the light curtain identification module is used for analyzing and reporting the current passage state to the master control module; the Uart communication module is used for executing communication between the master control module and the upper computer; and the Can communication module is used for executing communication between a master control board and a slave control board of the master control module. By arranging a double-controller architecture in the master control module in combination with the light curtain identification module which can effectively identify the light curtain detection state, the automatic gate control circuit realizes effective passage logic control, enhances emergency response capability to circumstances, such as overtime, reverse breakthrough, gate holding and fire alarms, and can be sufficiently applicable to practical application in high-flow gates.

Description

technical field [0001] The invention relates to the field of automatic control, and more specifically, to an automatic control circuit for a gate. Background technique [0002] Turnstiles, also known as channel gates, entrance and exit machines, etc., are a blocking access control device that regulates the flow of people and controls traffic. In addition to controlling traffic, ticket inspection is another indispensable function of the turnstile; it can be said that non-manual automatic ticket checking is the most common application field of turnstiles, and it is more typical to use turnstiles in rail transit stations such as subways and high-speed rails. Automatic access by swiping the card through the gate, and automatic ticket checking at the entrance through the gate in scenic spots, playgrounds, gymnasiums, entertainment venues and other places. [0003] The basic components of the turnstile include box shell, door wing, motor unit, control circuit and auxiliary equipm...

AI Technical Summary

Problems solved by technology

However, due to insufficient hardware processing capacity and single control process, the existing gate control system has limited ability to comprehensively judge information such as pedestrian position, ticket number, motor status, etc., and often makes wrong judgments on the traffic status, resulting in abnormal gate wings. Opening and closing cannot meet the actual needs, and even accidents that pinch pedestrians and obstruct traffic may occur
