Abstract:
In view of problems of high cost, low test efficiency and unable to record test data automatically of functional test methods of existing electro-hydraulic control system of hydraulic support, and in order to verify adaptability of control logic of the electro-hydraulic control system of hydraulic support to working condition of fully mechanized coal mining face, an automatic test platform of electro-hydraulic control system of hydraulic support was developed by taking SAC hydraulic support electro-hydraulic control system as research object. The test platform uses a test management platform to coordinate multiple test devices to execute test cases collaboratively, adopts simulation technology to simulate data changing process of various sensors, and uses multiple communication networks to real timely collect test data, uses switching of multiple relays to realize multi-function complex. The test platform can realize automatic configuration and management of port function of detection device according to the specific application of fully mechanized coal mining face, and can realize single function test, group function test, automatic following function test and automation adaptability test of working condition of fully mechanized coal mining face, which improves test efficiency and test accuracy, provides an effective means to study adaptability of the electro-hydraulic control system under complex working conditions such as roof caving and floor bump on fully mechanized mining face.
