Hydraulic support frame data collecting method, hydraulic support frame data collecting system and hydraulic support frame centralized control system

Abstract

The invention relates to a hydraulic support frame data collecting method, a hydraulic support frame data collecting system and a hydraulic support frame centralized control system. The hydraulic support frame data collecting method comprises the following steps of: obtaining the number of a located hydraulic support frame of a coal mining machine; determining the number of an adjacent hydraulic support frame of the coal mining machine according to the number of the located hydraulic support frame of the coal mining machine; and collecting the support frame information data of the hydraulic support frames according to the number of the located hydraulic support frame of the coal mining machine and the number of the adjacent hydraulic support frame of the coal mining machine. The support frame information data of the located hydraulic support frame and the adjacent hydraulic support frame of the coal mining machine are collected, and the polling of the data of all of the hydraulic support frames is not needed, so that a remote control center can timely obtain the effective hydraulic support frame data; the effective data transmission speed of the remote control center and a fully mechanized coal mining face is accelerated; meanwhile, the effective data transmission effect is accelerated, so that the operation speed of the coal mining machine can be properly accelerated; the automatic mining efficiency is further improved; and the hydraulic support frame data collecting method, the hydraulic support frame data collecting system and the hydraulic support frame centralized control system can be widely applied to the automatic mining field.

Description

Technical field [0001] The invention relates to the technical field of comprehensive mechanized coal mining in coal mines, in particular to a method and system for collecting data of a hydraulic support based on the position of a coal shearer. Background technique [0002] The working face of fully mechanized coal mining (comprehensive mechanized coal mining in coal mines) has a harsh environment and high labor intensity. More and more fully mechanized mining faces are remotely controlled at the remote control center to realize unmanned and automated coal mining in fully mechanized mining faces. In the process of automated mining at a fully mechanized coal mining face, the personnel of the remote control center must know the effective data of the hydraulic support in time and master the on-site mining conditions of the fully mechanized mining face in order to safely realize automated mining. Due to the harsh coal mine environment, the collected hydraulic support data is transmitt...

AI Technical Summary

Problems solved by technology

At present, the collection of hydraulic support data is to poll all hydraulic supports in the entire fully mechanized mining face. Although bus communication methods such as RS485 / CAN have the characteristics of stable data transmission, their transmission rate is relatively low. Polling the supports of all hydraulic supports The information data takes a long time, so the remote control center personnel cannot obtain effective support information data in time, resulting in low efficiency of automated mining
