Abstract:
At present, the remote centralized control loop of hydraulic support in fully mechanized mining face in coal mine is mostly independent or target type, and the efficiency of remote centralized control is low, which leads to the increase of attitude control deviation. Therefore, the design and verification analysis of remote centralized control method of hydraulic support for fully mechanized coal mine face based on Internet of Things RFID is proposed. According to the current test requirements, the attitude of the hydraulic support is set first, and the efficiency of remote centralized control is improved by using a multi-stage method to complete the multi-loop control. Based on this, the remote centralized control model of RFID hydraulic support for Internet of Things is constructed, and the remote centralized control processing is realized by means of adaptive correction and adjustment. The test results show that: for the selected 5 test hydraulic supports, the measurement comparison of the three groups, the final attitude control deviation is better controlled below 1.3, indicating that the remote centralized control effect of the hydraulic support designed by combining the Internet of Things RFID technology is better.
