Gate control device and system based on RS485 communication protocol

Abstract

The invention provides a gate control device and system based on an RS485 communication protocol and relates to the technical field of access control. The gate control device comprises a main control board, a servo driver, an encoder, a servo motor and a gate, wherein the main control board sends a control signal generated by a state monitoring device to the servo driver; the encoder detects the position of the gate, position information is obtained, and speed information is calculated according to the position information; the servo driver controls the servo motor according to the control signal, detects output three-phase current and compares the three-phase current, the position information and the speed information with default information, and a comparison result is obtained; the servo motor works according to the comparison result and the control signal of the servo driver and drives the gate to execute corresponding actions. The RS485 communication protocol is adopted for control, control is performed according to the operation state of the gate on the basis that networking control is simple and convenient to extend, and synchronous and stable operation is realized.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to a gate control device and system based on the RS485 communication protocol. Background technique [0002] With the vigorous development of high technology, intelligent management has entered people's social life to meet the needs of the information age. As an advanced high-tech preventive and manageable means, intelligent channel system has been widely used in some economically developed countries and regions It is widely used in schools, canteens, hotels, clubs, subways, stations, docks, and communities. The intelligent channel swing gate is based on industrial automation control and uses the computer network as a bridge to provide users with a comprehensive management that is safer, more reliable, more efficient and economical; [0003] At present, the traditional gates are generally difficult to network, and the operation is not synchronized, and there are problems of ...
