In order to solve problems of higher cost, complex computation, lower accuracy, inconvenience in installation and overhaul in current hydraulic support height measurement in underground coal mines, the invention provides a pressure type hydraulic support height detection system and a pressure type hydraulic support height detection method. The pressure type hydraulic support height detection system comprises a pressure sensor, a control module, a wireless transmission module, a power supply module and a hydraulic flexible pipe; one end of the hydraulic flexible pipe is hermetically connected with the pressure sensor, the other end is open, and the hydraulic flexible pipe is filled with liquid; and the control module is connected with the pressure sensor, the wireless transmission module and the power supply module. The pressure type hydraulic support height detection system and the pressure type hydraulic support height detection method have the characteristics of low cost, simple and accurate measurement and convenience in installation, and can better match with the coordination work of the fully mechanized coal mining face of the underground coal mine and improve the work efficiency of the fully-mechanized coal mining face.
Description
technical field [0001] The invention relates to a coal mine underground hydraulic support control system, in particular to a pressure-type hydraulic support height detection system and method. Background technique [0002] As the automation level of coal mining is getting higher and higher, the status monitoring and control of coal mining equipment in the fully mechanized mining face of coal mines has become an urgent need for domestic modern coal mines. There are a large number of hydraulic supports and frequent movements. It is necessary to frequently collect the height of the top beam head of the hydraulic support to complete the coordinated operation with coal mining machines and other coal mining and transportation equipment in the fully mechanized mining face. [0003] In underground mining, various types of hydraulic supports are used to perform the task of supporting the roof and preventing premature collapse of the roof support. During the movement of the hydraulic...
