  • With the continuous promotion of the construction of unmanned automated fully intelligent mechanized working faces, higher technical requirements have been put forward for the automation control function of the hydraulic support electrohydraulic control system. The electrohydraulic control technology developed in China has problems such as low communication speed, delayed response, and poor reliability in meeting the requirements of intelligent production technology. An end controller for the electrohydraulic control system of hydraulic support based on a 32-bit processor has been developed. A communication architecture of the end controller based on industrial Ethernet and CAN bus has been designed. According to the technical requirements of intelligent perception, intelligent decision-making, and automatic control for unmanned intelligent mechanized working faces, parameter inspection, parameter modification, online upgrade, and control functions of automatic follow-up have been designed in the end controller. In order to meet the requirements of standardization and normalization of data in the hydraulic support electrohydraulic control system in intelligent fully mechanized working faces, the end controller can encode the data generated by the hydraulic support electrohydraulic control system according to the data encoding standard based on tag numbers. Through the experiment on the "three machines" experimental platform of fully mechanized working faces, the results show the following points. The entire process from issuing inspection instructions to receiving data from 27 support controllers on the experimental platform takes 1.8 s for the end controller. It is 1.5 s faster than using RS485 communication to achieve parameter inspection. The size of the upgrade program sent by the end controller is 38 KiB and the transmission time is 1.2 s. After testing, it takes 4-6 s for all support controllers in the fully mechanized working face to receive the upgrade command and successfully upgrade together, achieving the expected goal. The end controller can control the corresponding hydraulic support to make correct actions based on the position of the shearer. It can meet real-time requirements.
