Abstract

The invention discloses a system and a method for automatically testing main control hardware of a fan on the basis of a PLC (Programmable Logic Controller). The testing system comprises a PLC main controller, an extendable data interaction module and a graphical debugging terminal; the data interaction module and a data interaction module of equipment to be tested are subjected to one-to-one interaction by a cable; and the PLC main controller of the testing system is used for rapidly acquiring information of the data interaction module of the testing system in an EtherCAT manner, respectively communicating with a main controller of the equipment to be tested and the graphical debugging terminal on the basis of an ADS (Automation Device Specification) protocol and implementing automatic testing on a loop of the main control system hardware of the fan. The system and the method have the advantages of good extendibility, strong applicability, high repeated utilization rate, reduction on debugging time, improvement on working safety and quality of a main control system of the fan and the like.

Description

technical field [0001] The invention relates to a PLC-based automatic testing system and method, in particular to a PLC-based fan main control hardware automatic testing system and testing method. Background technique [0002] As we all know, before leaving the factory, the main control system of the fan must undergo a comprehensive test to provide reliable guarantee for field use. The traditional method of testing the main control system of wind turbines is mostly manual, and several people cooperate to complete it, which is undoubtedly a waste of human resources. And for most engineers, hardware testing is a complicated and time-consuming process, because the items to be tested include: digital input and output hardware loops, analog input and output hardware loops (temperature signal, pressure signal, acceleration signal, position signal and wind speed signal) and key modules (safety relay, speed measurement module) and so on as many as hundreds. Under normal circumstan...
