Abstract: Aiming at the problem of automatic height adjustment of shearer, a shearer simulation cutting device with electro-hydraulic proportional height adjustment system was designed. The composition of the experimental device was analyzed. The NI PCIe-6323 data acquisition card and the electro-hydraulic proportional direction valve were used as the core hardware. The test & control system of shearer simulation height adjustment experimental device based on LabVIEW was constructed. The system has modules such as analog signal output, multi-channel data acquisition, real-time data display and storage. The paper carried out the hardware selection and the program design of each module of the system. The front panel and block diagram of the system were given, and the experimental verification was carried out. The experimental results show that the system can monitor the operating conditions of the experimental device in real time. The development of this system provides a platform for the experimental research of the subsequent automatic height adjustment of shearer.
