Gating-driven communication cascade circuit and gating-driven communication cascade method

Abstract

The invention discloses a gating-driven communication cascade circuit and a gating-driven communication cascade method. A main board controller is connected with multipath door motor drivers; three communication connecting lines are arranged between the main board controller and the first path of door motor driver; a communication data bus of the main board controller is electrically connected with a communication data bus of the first path of door motor driver, an IO data line of the main board controller is electrically connected with an IO data line of the first path of door motor driver,and a signal ground line of the main board controller is electrically connected with a signal ground line of the first path of door motor driver; cascading electric connection structures are sequentially adopted among the door motor drivers, and the IO data lines are sequentially cascaded with signal input and output IO lines used for modifying ID address enable signals of the drivers. The communication problem between the host and the multi-gate driver equipment can be better solved, the hardware research and development period and research and development cost of product updating and serialization can be reduced, and the system complexity and maintenance cost of product updating and serialization are reduced.

Description

technical field [0001] The present invention relates to a passage gate of an automatic induction door, in particular to a communication cascading communication mode of a gate control drive which is used on the passage gate of an automatic induction door to realize a main board controller to send commands and receive the communication mode of the door motor driver status reply Circuit and communication cascade method. Background technique [0002] Most existing gating drivers used on the channel gates of automatic sensing doors use digital IO ports for receiving commands and replying status when designing, but this can only realize related gating driving functions for current products. If you need to modify and add functions in the later stage, you need to add more IO ports for sending and receiving data (such as start and stop, brake, forward and reverse, speed signal, position signal, etc.), which leads to the need to generate hardware The R&D cycle also increases and the ...

Problems solved by technology

[0003] The present invention solves the problem that more IO ports need to be added for sending and receiving data when the gate driver used on the channel gate of the automatic induction door needs to be modified and added in the later stage, the hardware development cycle is long, and the research and development cost is relatively long. High, not conducive to quick and effective product updates and serialization, high system complexity and high maintenance costs, and provide a better solution to the communication problem between the host and multi-door drive equipment, which can reduce product updates and serialization The hardware R&D cycle and R&D cost reduce the system complexity and maintenance cost of product updates and serialization.
