It is preferred that the set distance is 5m.
The present invention realizes wireless short-distance control and controls two kinds of control models on the spot, infrared wireless communication distance limitation
Ensure the safe and effective of operator's control instruction；Solves advancing jack linkage control in left and right in equipment train moving process
Problem reduces Operating Complexity；The flexible monitoring function of left and right advancing jack oil cylinder is realized, accurate linkage control has been reached
Purpose；Voice interlocking early warning in equipment train moving process is realized, it is mobile to operator and periphery to reduce equipment train
The security risk of personnel.
Detailed description of the invention
Attached drawing 1 is the connection letter of control system in the control method of underground coal mine working face equipment train of the present invention
Figure.
Specific embodiment
The present invention is described in further detail combined with specific embodiments below.
A kind of underground coal mine step type equipment train control method, with independent control system, referring to attached drawing 1, control
System processed includes the electrofluidic control device installed in walking self-moving equipment vehicle, electromagnetic pilot valve group, solenoid-driven dress
It sets, advancing jack pilot valve, the first electric-hydraulic control reversing valve group, the second electric-hydraulic control reversing valve group, infrared wireless communication device, language
Mixer, stroke sensing device also have long-range hand-held remote control device, wherein electromagnetic valve actuator, left and right passage thousand
Jin top pilot valve, infrared wireless communication device, voice device, stroke sensing device are connected on electrofluidic control device, are connect
By electrofluidic control device action command and transmit data to it, the first electric-hydraulic control reversing valve group is connected to left and right advancing jack
On pilot valve, the second electric-hydraulic control reversing valve group is connected on electromagnetic valve actuator by electromagnetic pilot valve group, due to functionally
Be it is desirable, under normal circumstances, two it is electro-hydraulic control thread-changing valve groups movements need to synchronize.Electrofluidic control device is using directly or indirectly
Two ways controls electromagnetic priority valve and electric-hydraulic control reversing valve group, it is so-called directly refer to by be manually operated electrohydraulic control system into
Row control, it is so-called to refer to indirectly through operation remote control device come output services instruction, wirelessly it is transferred to electrichydraulic control
System is controlled.Operator realizes the control to equipment train, stroke sensing by electrofluidic control device or remote control device
Device is used to monitor the stroke of train jack stretching, guarantees the flexible synchronism of train two sides jack cylinder, infrared radio
Communication device and remote control device establish wireless connection at work, are used for transmission data, voice device is stored with set in advance
Sound bite can selectively play under the control of electrofluidic control device.
