Description

Technical Field

[0001] The present invention belongs to the technical field of remote control of pneumatic devices, and in particular relates to a pneumatic control device and method. Background Art

[0002] There are tens of thousands of gas extraction boreholes and extraction pipes in coal mines. Mechanical valves are installed on the extraction pipes to adjust the conduction status of the extraction pipes. Currently, manual adjustment is mainly relied on. Due to the large number of borehole extraction pipes, the labor intensity is high, and the adjustment frequency is low. When problems such as gas leakage and blockage are detected in the boreholes, the boreholes cannot be closed remotely in time. At the same time, the conduction status cannot be timely and reasonably adjusted according to the extraction conditions of each borehole. There are problems such as unreasonable negative pressure distribution, which affect the extraction efficiency and effect.

[0003] If a group of electric or pneumatic valves are installed on the borehole connecting the extraction pipe, the conduction state of the extraction pipe is controlled by remotely controlling the state switching of the electric or pneumatic valves. Although automation can be achieved, the control of the electric valves requires a large amount of electrical control wiring; existing pneumatic valves also mostly use solenoid valves to control the action, which requires a large amount of wiring and PLC or CPU control points. Since coal mines, especially gas extraction sites, have strict control over live equipment (for example, cables are not allowed to be laid above the extraction pipeline), even for mining explosion-proof electrical equipment, due to the large number of boreholes, there is a greater risk of explosion failure and safety hazards if it is installed and used in large quantities. In addition, a large amount of wiring and debugging makes the system construction more complicated and the subsequent maintenance is inconvenient. In addition, mining explosion-proof electrical equipment is generally sold at a high price, the system cost is high, and it is difficult to promote and apply on a large scale.

[0004] In order to solve the above problems, there is an urgent need for a pneumatic control device and method to realize remote automatic control of massive pneumatic devices (such as pneumatic valves), without the need for a large number of live equipment or a large amount of wiring. The system is easy to install and maintain, low in cost, and suitable for promotion and application. Summary of the Invention

[0005] The present invention addresses the aforementioned issues and overcomes the shortcomings of the prior art by providing a pneumatic control device and method. By using a mobile positioning platform to drive air supply pipelines to supply air to various pneumatic devices in a time-sharing manner, the present invention enables remote control of a large number of pneumatic devices, eliminating the need for the installation of extensive explosion-proof electrical equipment for mining.
