Abstract
The invention discloses a gas detection alarm system based on ZigBee. The gas detection alarm system based on the ZigBee comprises a gas detector installed in a field needing gas detection, a degassing device, a monitoring center and a GSM communication module, wherein the degassing device, the monitoring center and the GSM communication module correspond to the gas detector. A ZigBee ad-hoc network is established in the field needing gas detection and comprises a ZigBee terminal used for collecting the state of the gas detector and controlling the work state of the degassing device and a ZigBee coordinator interacting with an upper computer. According to the gas detection alarm system based on the ZigBee, the monitoring center does not need to be directly connected with the gas detector and the degassing device through lines, remote data information transmission can be completed just through the ZigBee ad-hoc network and the GSM communication module, the gas detection alarm system based on the ZigBee can be widely used for monitoring and controlling gas leakage in the fields of fire protection, petrochemical engineering, urban gas and the like, and the advantages of the gas detection alarm system based on the ZigBee can be fully expressed on the occasion where the lines can not be arranged between the monitoring center and the gas detector.
Description
Technical field
The present invention relates to industrial control field, be specifically related to a kind of gas detection alarm system based on ZigBee.
Background technology
Along with the continuous progress of society, China's living standards of the people are also improving constantly.In modern society, there are various gas detection alarm systems, data communication between these gas detection alarm system equipment generally all adopts 485, CAN communications protocol, gas detector and watch-dog all carry out data communication by wired connection mode, to installation brought a lot of troubles and installation wiring cost high.And cannot connect up between some occasion controller and detector, so existing gas detection alarm system just cannot be applied in related occasion.
Summary of the invention
?the present invention overcomes the deficiency that prior art exists, and technical matters to be solved is for providing a kind of gas detection alarm system based on ZigBee.
To achieve these goals, the present invention adopts following technical scheme:
A gas detection alarm system based on ZigBee, is included in field erected at least one gas detector that need to detect gas, the depassing unit corresponding with described gas detector, Surveillance center and gsm communication module; At the scene that need to detect gas, set up ZigBee MANET, described ZigBee MANET comprises for gathering described gas detector state, controlling the ZigBee terminal of described depassing unit duty, and carries out mutual ZigBee telegon with host computer.
Further, described gas detector is combustible gas probe or toxic and harmful detector.
Further, described gsm communication module is installed on ZigBee telegon inside.
Gas detector can be arranged on corresponding places as required, and can arrange to realize a plurality of detection of gas of difference in functionality, meanwhile, corresponding depassing unit is set.Gas detector and depassing unit are connected to ZigBee MANET, by gsm communication module and Surveillance center, carry out telecommunication, realize remote alarms and control.
The invention has the beneficial effects as follows: between Surveillance center and gas detector, depassing unit, do not need direct line, as long as utilize ZigBee MANET and gsm communication module just can complete the transmission of teledata information, system architecture is simple, disposable less investment, be convenient to install, convenient operation and maintenance management, can be widely used in the Leakage Gas monitoring in the fields such as fire-fighting, petrochemical industry, gas.The occasion that cannot connect up between some Surveillance center and gas detector more can show advantage of the present invention.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is the circuit structure block diagram of gas detection alarm system of the present invention.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of gas detection alarm system based on ZigBee, is included in field erected at least one gas detector that need to detect gas, the depassing unit corresponding with described gas detector, Surveillance center and gsm communication module; At the scene that need to detect gas, set up ZigBee MANET, described ZigBee MANET comprises for gathering described gas detector state, controlling the ZigBee terminal of described depassing unit duty, and carries out mutual ZigBee telegon with host computer.
Gas detector can be set to combustible gas probe or toxic and harmful detector etc. according to service condition.In addition, it is inner that gsm communication module is installed on ZigBee telegon, is combined into a product.
Take certain chemical plant as test terminal, set up ， Surveillance center of Surveillance center that a gsm communication module is installed in the place of needs, the computing machine of Surveillance center communicates by RS232 interface and gsm communication module.One or more gas detectors and corresponding depassing unit are installed respectively in each warehouse, and a plurality of ZigBee terminals are connected with depassing unit with gas detector respectively, and carry out the transmission of information by ZigBee wireless self-networking network and ZigBee telegon.
In use, gas detector Real-Time Monitoring environmental gas concentration, the monitor value that ZigBee terminal gathers gas detector arrives ZigBee telegon by wireless network transmissions, then is transferred to Surveillance center by gsm communication module.When meeting or exceeding preset value Shi， Surveillance center, gas concentration sends sound and light alarm, to point out user.User can send order to gsm communication module by the computing machine of Surveillance center, gsm communication module sends to order the ZigBee telegon in warehouse, the control command that ZigBee telegon sends according to Surveillance center, to corresponding ZigBee terminal, send control command, thereby start corresponding depassing unit.
Above-described embodiment is just to allow one of ordinary skilled in the art can understand content of the present invention and implement according to this for technical conceive of the present invention and feature being described, its objective is, can not limit the scope of the invention with this.Every equivalent variation or modification that according to the present invention, the essence of content has been done, all should be encompassed in protection scope of the present invention.
