Simulation test system of hydraulic support electro-hydraulic control system

Abstract

Provided is a simulation test system of a hydraulic support electro-hydraulic control system. The simulation test system comprises a small hydraulic support model, a hydraulic support display board, a simulation device, and a PC server, the small hydraulic support is provided with a plurality of sensors and used for displaying the movement of a hydraulic support and attitude of each part of the support, the hydraulic support display board is used for displaying the movement of the hydraulic support and the states of main sensors in a graphic visual manner, the simulation device is electrically connected with the sensors and used for receiving data of the sensors and performing preliminary processing of the data, and the PC server is electrically connected with the simulation device and used for receiving the data after preliminary processing by the simulation device and performing post-processing of the data and downloading on-site system operation data to a test system and performing reproduction of the on-site operation data and simulation of the system operating environment. According to the simulation test system, the on-site system operation data is collected and downloaded to the test system and is mutually integrated with the simulated test system via a control system, and the laboratory simulation tests in the condition of on-site environment are realized.

Description

technical field [0001] The invention relates to a simulation test system of a hydraulic support, in particular to a test system for simulating an electro-hydraulic control system of a hydraulic support. Background technique [0002] The hydraulic support electro-hydraulic control system can reduce the labor intensity of underground workers, improve the production efficiency of coal mines, and provide important support for unmanned mining of coal mines. At present, there are many types of hydraulic supports, and the hydraulic support control systems of different projects need to detect the diversification and diversification of information on equipment status and working conditions. The actions are also inconsistent, resulting in the diversification of the software of the electro-hydraulic control system of the hydraulic support and the complexity of the test. In addition, the research and testing of the hydraulic support control system software is still in the stage of phys...

Problems solved by technology

[0004] CN201220348324 discloses a remote analog control system for hydraulic props for computer teaching, including pressure sensors, displacement sensors and positioning sensors arranged on the hydraulic props, the remote analog control system layer includes several interface managers, the interface managers have electromagnetic It is composed of valve group, data collector and operation panel, and each interface manager corresponds to a hydraulic support in the physical layer; the system control layer includes two main controllers, several I / O controllers and the The connection bus of the long instruction control word, the two main controllers and several I / O controllers are connected through the connection bus; but it lacks functions such as hydraulic support model management and action interference, and only collects the connected sensors, electromagnetic The valve is controlled to realize the communication between the I / O controller and the main controller, and the hydraulic support model is a physical hydraulic support model, driven by a hydraulic system, which is expensive and inconvenient to move

[0005] Therefore, there are certain imperfections in the hydraulic support simulation test devices in the prior art, and there is an urgent need in this field for a hydraulic support control system simulation test device with accurate and reliable simulation effects, low cost, and convenient testing.
