Mining remote control system for coal bed fracturing

Abstract

The technology of the invention relates to a mining remote control system for coal bed fracturing, which is disclosed by aiming at the defect of in-situ manual operation of a traditional coal mine fracturing pump package. The mining remote control system for the coal bed fracturing comprises a mining anti-explosion soft start cabinet, a programmable logic controller (PLC) cabinet, an anti-explosion mining computer, a camera display, a PLC, an electric pressure regulating valve, a fracturing pump, an electric control hydraulic speed changer, a motor and a cooling pump, wherein the PLC is respectively connected with the anti-explosion mining computer, the camera display, the PLC, the electric pressure regulating valve, the fracturing pump, the electric control hydraulic speed changer, the motor and the cooling pump, and simultaneously, the electric pressure regulating valve, the fracturing pump, the electric control hydraulic speed changer and the motor are connected in sequence. In themining remote control system for the coal bed fracturing, acquisition and processing are performed on a control signal, the control signal is transmitted to the anti-explosion mining computer throughan optical fiber, and then, data monitoring and remote operation are performed through the anti-explosion mining computer. Two-way transmission is performed on the data through the optical fiber, thereby, not only is the remote control distance prolonged, but also the control reliability is greatly improved. By using the anti-explosion mining computer, the operation precision of the control system is higher, and the man-machine interaction capacity is further improved when the operation is reliable, convenient and fast. The remote control distance can reach at least 1500m.

Description

technical field [0001] The technology of the invention relates to the technical field of coal mining equipment, in particular to the control system of the coal mining equipment. Background technique [0002] The coal industry is a national pillar industry, among which the world's major coal-producing countries attach great importance to the development of coal-bed methane. As a high-quality, high-efficiency and clean energy, coalbed methane has a broad prospect for its large-scale development and utilization. The development and utilization of coalbed methane also has multiple effects: improving the level of prevention of gas accidents, overcoming the problems of previous pump group operations in high-pressure areas and fracturing. Disadvantages of abnormal gas induced during the process. [0003] The existing domestic and foreign products basically do not have the remote operation performance of mining equipment. Due to the particularity of the underground working environm...

Problems solved by technology

[0003] The existing domestic and foreign products basically do not have the remote operation performance of mining equipment. Due to the particularity of the underground working environment of coal mines, the working environment of the equipment is in a "double-dangerous environment" that is, gas outburst and fracturing high-pressure areas. It is necessary to ensure the safety and reliability of the equipment in operation, and more importantly, the personal safety of the operators.
