The novel inner structure gas imager comprises a laser device, wherein an output end is arranged at the front end of the laser device; the front end and the rear end of the laser device are respectively connected with a laser power supply and a laser power supply cooling system module; an input end which is convenient for light to input is arranged at the upper end of the output end; a microscopic optical detector is arranged at the rear side of the input end; and the rear end of the microscopic optical detector is sequentially connected with an amplification system, an A/D (Analogue/Digital) conversion unit with an FPGA (Field Programmable Gate Array) module and a processor. The novel inner structure gas imager disclosed by the invention has the advantages that the technical scheme can realize all-weather observation of the imager; the detection sensitivity can reach the optimal effect; and the defects including an SF6 gas leaking point and the like can be clearly and accurately positioned.
Description
Technical field
The invention belongs to optical technical field, refer to a kind of imager especially, especially a kind of new internal structure gas imaging instrument.
Background technology
Current SF6 gas is mainly used in the power industry.SF6 gas is used for 4 types electrical equipment as insulation and/or arc extinguishing; SF6 isolating switch and GIS(refer to the sulfur hexafluoride gas insulated metal enclosed swit chgear here, are called " gas-insulated switchgear " in the world), SF6 on-load switch equipment, SF6 insulation transmission of electricity pipeline, SF6 transformer and SF6 insulation transformer station.80% is used for the high pressure power equipment.SF6 also is a kind of greenhouse gases simultaneously, the SF6 gas molecule has huge harm to greenhouse effect, because molecule of SF6 gas is to for the carbon dioxide molecule in our daily life 25000 times of greenhouse effect influences, this shows, SF6 with respect to environmental disruption very severe carbon dioxide be how serious, simultaneously, the life-span that SF6 exists in the atmosphere is quite long, under extreme weather, form some poison gas harm atmospheric envelopes easily, therefore whether detect it leaks and seems important relatively, pass through bandaging strapping before this, the soap bubble method detects and all seems too complicated, and frequent and electric equipment danger very, detect by imager at present and just seem very convenient, but present imager still exists the some shortcomings part; Such as realizing round-the-clock observation, detection sensitivity does not reach best effect yet, can not clear and accurate locate drawbacks such as SF6 gas leak source.
Summary of the invention
The objective of the invention is to have the problems referred to above at existing technology, proposed a kind of compact conformation, can round-the-clock observation and the imager of location SF6 gas leak source.
For achieving the above object, the present invention has adopted following technical proposal: a kind of new internal structure gas imaging instrument, comprise laser instrument, the laser instrument front end is provided with output terminal, laser instrument front end rear end is connected with Laser Power Devices and Laser Power Devices cooling system module respectively, it is characterized in that, described output terminal upper end is provided with the input end of being convenient to the light input, the input end rear side is provided with the microoptic detector, and microoptic detector rear end is connected with A/D converting unit, the processor of amplification system, band FPGA module in turn.
In above-mentioned a kind of new internal structure gas imaging instrument, also be provided with indication laser between described input end and the microoptic detector.
In above-mentioned a kind of new internal structure gas imaging instrument, described processor is connected with display.
Compared with prior art, the invention has the advantages that: the technical program can realize the round-the-clock observation of imager, and detection sensitivity reaches best effect, can clear and accurate locate drawbacks such as SF6 gas leak source.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 synoptic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, a kind of new internal structure gas imaging instrument, comprise laser instrument 1, the laser instrument front end is provided with output terminal 2, laser instrument front end rear end is connected with Laser Power Devices 3 and Laser Power Devices cooling system module 4 respectively, described output terminal upper end is provided with the input end 5 of being convenient to the light input, and the input end rear side is provided with microoptic detector 6, and microoptic detector rear end is connected with A/D converting unit 7, the processor 9 of amplification system 7, band FPGA module 8 in turn.Also be provided with indication laser 10 between described input end and the microoptic detector.Described processor is connected with display 11.During work, output terminal is launched laser, and toward external diffusion, this SF6 molecular flow will produce stronger photonic absorption and photon back scattering to the three-dimensional radiation field laser that covers this zone to the SF6 gas molecule that leaks out with flow phenomenon.Because optical absorption, leak certainly exists the flow perturbation phenomenon.After the laser reflection, the high sensitivity microoptic detector that installation is complementary receives, just constitute the ultimate principle in SF6 laser leakage detecting instrument inside, according to the technical parameter requirement of detection system, the electronics signal under the record of high sensitivity microoptic detector can be converted into analog quantity.With large-scale programmable logic device (PLD) FPGA module controls high speed analog-to-digital conversion unit, the data of output are carried out image for 32 high speed embedded systems and are handled, the outputting standard vision signal can directly drive colour liquid crystal display device, regulate biasing and the gain of picture signal, the optical lens manual focusing.It is vaporific to present SF6 gas black smoke at viewfinder and liquid crystal display.Thereby clear and accurate finds the leakage point of SF6 gas.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
