Description
Technical field
A kind of anti-explosion gas thermal imaging detection means is the utility model is related to, is related to thermal imaging detection, more particularly to it is a kind of
Anti-explosion gas thermal imaging detection means.
Background technology
Because gas leakage causes the field such as petrochemical industry accident to occur frequently, so far still without a kind of effective method
Accident is accomplished satisfactorily to prevent.Conventional security means of defence is partial to physical isolation, personal management, passive detection, its
Middle physical isolation method fundamentally can not be prevented and be prevented to accident；The influence factor accounting of personal management is heavier；And
Often accident has occurred and that passive detection method, just sends early warning.At present, although in the presence of some infrared monitoring equipment, it can be found that
Gas leaks and carries out early warning, but can not accomplish distributed extensive Centralized Monitoring management.For example, methane/ethylene gas physical examination
Leak infrared thermoviewer.U.S.'s FLIR companies GasFindIR serial gas imager and French Bertin companies Second Sight
Gas imaging instrument, above can not be distributed big in application although can preferably be detected to gas leakage to a certain extent
Scale land management monitoring management, more it is not bound with the specific production link of specific area and carries out preventative analysis and early warning.
In view of this, the utility model aims to provide a kind of anti-explosion gas thermal imaging detection means, to solve prior art
Deficiency.
Utility model content
The purpose of this utility model is to provide a kind of anti-explosion gas thermal imaging detection means, is easy to distributed deployment and group
Build distributed monitoring detection network.
In order to reach above-mentioned purpose of the present utility model, the thermal imaging detection means of the utility model gas is by infrared acquisition
Device connect backward gas leakdetector again backward connect network transmitter and power module composition, the infrared detector by
Camera lens, optical filter and infrared movement composition, the optical filter between the camera lens and the infrared movement, let out by the gas
DSP module built in leak detection device and ARM modules, the DSP module are gas detection modules, the ARM modules be video acquisition,
Compression and control module.
In certain embodiments, it may be preferable that the DSP module has TMS320DM8148 chips.
In certain embodiments, it may be preferable that there is integrated explosion-proof window before the camera lens.
In certain embodiments, it may be preferable that network transmission module is gigabit networking transport module and by TCP/IP interfaces
It is connected to LAN.
In certain embodiments, it may be preferable that the infrared movement is uncooled ir movement.
In certain embodiments, it may be preferable that respective wavelength is inserted between the infrared movement and the camera lens as needed
Narrow band pass filter, wherein, for unsaturation hydrocarbon gas, select optical filter of the centre wavelength for 10744nm.
The utility model anti-explosion gas thermal imaging detection means is by infrared detector, gas leakdetector, network transmission
Device and power module form the device of an independent thermal imaging detection gas with detection gas leakage feature, particularly
DSP module is combined with, can fully achieve and the judgement whether detected gas leaks is made in the present apparatus, it is not necessary to relies on distal end
Server does the judgement.Independent detection ability possessed by the utility model anti-explosion gas thermal imaging detection means, in distribution
The dependence and configuration to disposing address can be reduced during deployment, reduces the pressure of far-end server, especially concurrent operation pressure,
The distributed detection system set up using the utility model anti-explosion gas thermal imaging detection means will not be because of the utility model
The individual defects of anti-explosion gas thermal imaging detection means or error cause whole system to interrupt or redeploy.In a word, this practicality
New type explosion proof air heat imaging detection device greatly facilitates distributed deployment, can reduce the installation and operation of distributed deployment
Cost, also enhance the robustness of whole distributed deployment.

The device of the vertical anti-explosion thermal-imaging detection gas with detection gas leakage feature, is particularly combined with DSP module, can be complete
Realize entirely and the judgement whether detected gas leaks is made in this explosion-protection equipment, it is not necessary to rely on far-end server and do the judgement.
Independent detection ability possessed by the present embodiment anti-explosion gas thermal imaging detection means, can be reduced to portion in distributed deployment
The dependence and configuration of address are affixed one's name to, the pressure of far-end server, especially concurrent operation pressure is reduced, uses the anti-gas explosion of the present embodiment
The distributed detection system that body heat imaging detection device is set up will not be because of the present embodiment anti-explosion gas thermal imaging detection means
Individual defects or error cause whole system interrupt or redeploy.In a word, the present embodiment anti-explosion gas thermal imaging detection dress
Put and greatly facilitate distributed deployment, installation and the operation cost of distributed deployment can be reduced, also enhance whole distribution
The robustness of deployment.
