Mining remote control system for coal bed fracturing

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.
