Description

Based on ZigBee technology coal mine underground safety monitoring system
Technical field
The utility model relates to a kind of underground safety monitoring system, and is particularly a kind of based on ZigBee technology coal mine underground safety monitoring system.
Background technology
ZigBee is the synonym of IEEE 802.15.4 agreement.Technology according to this agreement regulation is the wireless communication technology of a kind of short distance, low-power consumption.Its communication distance from 75 meters of standard to hundreds of rice, several kilometers, and support infinite expanding.In theory, ZigBee be one by a wireless-transmission network platform can how forming to 65000 wireless transport modules, in whole network range, can intercom mutually between each ZigBee network transmission module.The ZigBee network mainly is to set up for industry spot automation control data transmission, thereby it has simply, and is easy to use, reliable operation, the characteristics that price is low.Particularly, ZigBee network following points advantage:
1) low-power consumption.Under the low power consumption standby mode, No. 5 dry cells of 2 joints can be supported 1 node work 6~24 months, even longer.This is the outstanding advantage of Zigbee.The bluetooth of comparing down can only be worked several weeks; WiFi works a few hours only.
2) low cost.By significantly simplify agreement (less than bluetooth 1/10), reduced requirement, by forecast analysis to communication controler, 8 8-digit microcontrollers measuring and calculating with 8051, Full Featured host node needs the 32KB code, and the subfunction node is few to the 4KB code, and Zigbee exempts from the agreement patent fee.The price of every chip block is approximately 2 dollars.
3) low rate.Zigbee be operated in 20~250kbps than low rate, the initial data throughput of 250kbps (2.4GHz), 40kbps (915MHz) and 20kbps (868MHz) is provided respectively, satisfy the application demand of lower rate transmissions data.
4) prolong in short-term.The response speed of Zigbee is very fast, generally changes duty over to from sleep and only needs 15ms, and the node connection enters network only needs 30ms, has further saved electric energy.Compare down, bluetooth needs 3~10s, WiFi to need 3s.
5) high power capacity.That Zigbee can adopt is starlike, sheet and mesh network topology, and by a host node management plurality of sub node, maximum host nodes can be managed 254 child nodes; Host node also can be formed the big net of 65000 nodes at most by the last layer network node control simultaneously.
6) high safety.Zigbee provides three level security patterns, comprises no security settings, uses Access Control inventory (ACL) to prevent the symmetric cryptography that illegally obtains data and adopt Advanced Encryption Standard (AES 128), to determine its security attribute flexibly.
7) unlicensed band.Adopt DSSS in industrial science medical treatment (ISM) frequency range, 2.4GHz (whole world), 915MHz (U.S.) and 868MHz (Europe).
Each Zigbee network node not only itself can be used as monitored object, for example the sensor that it connected directly carries out data acquisition and monitoring, automatically other network node of transfer passes the data information of coming, and therefore can not influence the proper communication of whole network when a network node breaks down.
Existing coal mine downhole safety detection system generally is the mode of wire transmission, the complexity but this mode connects up, and the cost height, in case transmission cable damages, then whole monitoring system can't operate as normal.The employing Wireless transmission mode is also arranged, generally be based on the GPRS Radio Transmission Technology, but this mode is with high costs, the tunnel complex environment needs a large amount of base stations, maintenance difficulties height.
Therefore, need the wireless underground safety monitoring system of a kind of good stability, low cost, low-power consumption, can utilize the ZigBee procotol to carry out transfer of data.
The utility model content
In view of this, the utility model provides the wireless underground safety monitoring system of a kind of good stability, low cost, low-power consumption, can utilize the ZigBee procotol to carry out transfer of data.
Of the present utility modelly comprise sensor, locator and Surveillance center based on ZigBee technology coal mine underground safety monitoring system, sensor is arranged at the underground monitoring point; Described Surveillance center comprises server and the display terminal that is connected with the server output; Described server is connected with the server wireless transport module, sensor is connected with the sensor wireless transport module, locator is connected with the locator wireless transport module, connects into wireless data transmission network by the ZigBee procotol between server wireless transport module, sensor wireless transport module and the locator wireless transport module.
Further, described locator wireless transport module also is connected with acoustic-optic alarm, and acoustic-optic alarm is connected with server by the ZigBee procotol;
Further, described sensor comprises that microseismic sensors, temperature pick up, firedamp sensor are or/and dust sensor;
Further, also be provided with the router of built-in ZigBee wireless transport module (6) every a segment distance in the down-hole.
The beneficial effects of the utility model are: each sensor, be communicated with by the ZigBee procotol between locator and the server, can be to the gas bearing capacity of underground work environment, safety indexs such as temperature are monitored in real time, and the operating position of grasping the operating personnel in real time, can carry out early warning to accident, when meeting accident, can implement rescue to stranded staff rapidly, when indivedual wireless transport modules break down, do not influence the normal operation of whole system, and this system cost is cheap, power consumption is little, and the conventional DC power supply promptly can be wireless transport module long-time power supply is provided.
