Escalator control system and construction method thereof

Abstract

The embodiment of the invention relates to the technical field of escalators and discloses an escalator control system and an establishment method thereof. The control system comprises a terminal, a PLC and an escalator main control panel. N input points of the escalator main control panel are connected with N output points of the PLC correspondingly. M output points of the escalator main controlpanel are connected with M input points of the PLC correspondingly. The terminal controls connection relation between all the output points and the input points of the escalator main control panel through connection relation between all the input points and the output points of the PLC, and controls all the input points of the escalator main control panel to be connected or disconnected by controlling all the output points of the PLC to be connected or disconnected. A user just needs to control the PLC to achieve the effect when some output signals and input signals of the escalator main control panel need to be kept consistent, and hardware wiring does not need to be changed. By controlling the output points of the PLC to be connected or disconnected only, the input points of the escalator main control panel can be controlled to be connected or disconnected, and thus the control process is simpler, rapid and accurate.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of elevators, in particular to an escalator control system and a construction method thereof. Background technique [0002] Escalators are mostly used in places with large traffic such as subways, airports, shopping malls, and stations. According to different applications, customers have different functional requirements for escalators. In order to meet the needs of different customers, elevator suppliers need to constantly modify the software program of the escalator main control board. For the sake of functional perfection and safety, the software program of each newly designed main control board needs to be rigorously debugged and tested before leaving the factory. In order to develop, debug and test the software program of the escalator main control board, it is necessary to easily, quickly and effectively build the minimum control system of the escalator to ensure that the standar...

AI Technical Summary

Problems solved by technology

The more ports that have definition changes in the system (taking an escalator main control board and 3 expansion boards as an example, the total number of input and output ports is about 100), the more complicated and time-consuming it is to change the hardware wiring

On the other hand, when using the system built in this way, if you need to control the on and off of a certain input point, you need to manually short the input point and the common terminal of the input point through a wire. If you need to control the conduction of multiple input points To close, you need to short multiple wires in the same way, which is very inconvenient to disassemble

It can be seen that the control system built in the prior art has the following deficiencies: 1) the modification of hardware wiring is time-consuming and laborious. The conduction and closure need to be shorted by wires, which is inconvenient to disassemble
