Description
Technical field
This utility model relates to a kind of system, relates more specifically to a kind of coal mine gas monitoring and controlling system.
Background technology
Due to the restriction of coal mine gas monitoring and controlling system technology, effective control to Gas Disaster accident is not fully achieved yet,
Colliery gas accident great, especially big happens occasionally.Knowable to the data analysis of the statistics of coal mining accident in recent years, in various collieries thing
The first explosion accident being all Yin Wasi and causing is occupy in therefore.
Utility model content
For the defect of prior art, this utility model provides a kind of coal mine gas monitoring and controlling system.
A kind of coal mine gas monitoring and controlling system, it is characterised in that include being positioned at aboveground monitoring computer and being positioned at down-hole
Surveillance center's node and multiple wireless sensor network node, described monitoring computer is with Surveillance center's node by optical fiber even
Connect；Described Surveillance center node includes single-chip microcomputer, described single-chip microcomputer respectively with photoelectric alarm module, key-press module and radio-frequency antenna
Being connected, described single-chip microcomputer is communicated to connect with the plurality of wireless sensor network node by radio-frequency antenna；Described wireless sensing
Device network node is gathered front end, driving circuit for electromagnetic valve, CC2591 power amplification mould by CC2530 communication module, gas density
Block, reset circuit, serial communication and power management module composition.
The beneficial effects of the utility model are: can ensure that the gas density in mine is all the time in the range of safety value, it is ensured that
The safety of production and workmen.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model monitoring system；
Fig. 2 is the structural representation of sensor network nodes.
Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The detailed description of the invention of utility model is described in detail, and makes above and other purpose of the present utility model, feature and advantage incite somebody to action
Become apparent from.The part that reference instruction identical in whole accompanying drawings is identical.Accompanying drawing the most drawn to scale, emphasis
It is purport of the present utility model is shown.
As it is shown in figure 1, monitoring system is divided into aboveground and down-hole.The aboveground Surveillance center being mainly made up of computer, well
Under be the node of wireless sensor network.Wireless sensor network node, as the distribution node of star wireless network, is used for adopting
Collection gas density and the controller as gas exhaust system；Wireless sensor network is used for gathering gas density, uses wireless
Mode transfers data to wireless sensor node, and wireless sensor node uses bus communication mode the data collected to be passed
Deliver to the Surveillance center on ground, it is achieved the real-time monitoring of gas density.RF module transfer only with CC2530, it is impossible to reach to pass
Defeated required distance, therefore uses the radio frequency front end chip CC2591 of the 2.4GHz of TI company to improve the transmitting merit of radio communication
Rate, solves power amplification problem, improves it further and launches and receiving sensitivity, thus extends communication distance.
As can be seen from Figure 2 wireless sensor network node is gathered front end, electricity by CC2530 communication module, gas density
Electromagnetic valve driving circuit, CC2591 power amplifier module, antenna, reset circuit, serial communication, sound and light alarm, numeral method, press
Key and power management module composition；Consideration system has the features such as interference non-linear, many, multiple coupled, purely retarded, have employed mould
Stick with paste pid control algorithm and carry out control gas concentration.First set the gas concentration of a standard, i.e. mine safety production value.Pass through
Gas density in the real-time monitoring mine of firedamp sensor, if gas density is higher than standard value, there is the danger of gas explosion in mine
Danger, now by fuzzy-adaptation PID control gas density, if i.e. actual measurement gas concentration and standard value difference are the biggest, electromagnetic valve is inhaled
The conjunction time is the longest, and gas exhaust pump operation time is the longest, until actual measurement gas concentration disconnects less than standard value, electromagnetic valve,
Gas exhaust pump quits work, it is ensured that the gas density in mine is all the time in the range of safety value, it is ensured that produce and constructor
The safety of member.
Elaborate a lot of detail in the above description so that fully understanding this utility model.But above description
Being only preferred embodiment of the present utility model, this utility model can be to be much different from alternate manner described here
Implementing, therefore this utility model is not limited by disclosed above being embodied as.The most any those skilled in the art exist
Without departing under technical solutions of the utility model ambit, the method and the technology contents that all may utilize the disclosure above are new to this practicality
Type technical scheme makes many possible variations and modification, or is revised as the Equivalent embodiments of equivalent variations.Every without departing from this
The content of utility model technical scheme, any simply repaiies made for any of the above embodiments according to technical spirit of the present utility model
Change, equivalent variations and modification, all still fall within the range of technical solutions of the utility model protection.
