Description
Technical field
This utility model relates to a kind of mine gas extraction system, specifically Fuzzy PID and wireless sensor network technology is applied in mine gas extraction system, devises a kind of mine gas extraction system based on wireless sensor network。
Background technology
In mine, gas density is one of important indicator of mine safety。Due to the property complicated and changeable of coal production environment, the uncertainty of constantly intensification and the geological conditions of getting working face, brings various interference to coal mine gas drainage in addition。And other parameter association degree such as gas state parameter information and the temperature in tunnel, dust and wind speed are bigger so that gas monitor data have uncertainty and ambiguity, and therefore intelligent wireless sensor network is applied particularly significant in mine gas extraction system。
Summary of the invention
The purpose of this utility model is to devise a kind of mine gas extraction system based on wireless sensor network to solve existing issue, including remote computer, RS-485 transducer, Centroid, sensor acquisition node, DAC, valving。Wherein, Centroid includes having the microprocessor of Fuzzy PID, radio-frequency front-end, antenna；Sensor acquisition node includes multiple gas density being positioned at diverse location and gathers sensor, it is possible to this node carries out the collection of real-time gas density, can also receive and transmission information simultaneously；Valving effect is that the switch controlling gate valve carrys out the concentration of control gas。Its operation principle is as follows: with wireless sensor network system for core, substantial amounts of wireless sensor network acquisition node is positioned over the position of gas density to be monitored。Microprocessor in Centroid and remote computer are communicated by RS-485 transducer, the command information that remote computer is sent is transmitted to sensor acquisition node by radio-frequency front-end and antenna, the acquisition node consistent with oneself address Real-time Collection to methane gas concentration information utilize the mode of radio communication to be delivered to Centroid, return to microprocessor through radio-frequency front-end and antenna and show on the remote computer, microprocessor will receive after Information Pull Fuzzy PID processes and draw a current control output valve simultaneously, this output valve converts digital signals into through DAC and is transferred to valving after analogue signal。When in mine, gas density is too low, gate valve is opened, and otherwise valve Guan Bi, goes out gas pumping, realize gas density intelligentized control method whereby；Described microprocessor includes fuzzy controller。
This utility model is according to actual condition of mines and the real needs to mine gas parameter monitoring, wireless sensor technology is applied in coal mine gas monitoring and controlling system, wireless sensor node can adopt manual type to carry out flexible configuration, monitoring requirements according to change also can increase and decrease at any time simultaneously, it is achieved the non-blind area of mine environmental parameter is monitored。This utility model forwards the work such as transmission, route maintenance to transfer to wireless center node to complete complicated data process, access process, data, it is possible to decrease because multi-hop wireless transmits the error in data caused, alleviate leading portion information processing capacity。Microprocessor in Centroid of the present utility model includes fuzzy controller, and by fuzzy PID algorithm, the gas density in mine is controlled by the folding controlling valving, to reach safety in production, it is achieved the intelligentized control method of coal mine gas drainage。
