Hydrocarbon, alkene and aromatic hydrocarbons) etc., when such gas exceedes finite concentration, the eyes and respiratory tract of people can be stimulated, and further damage people
Liver, kidney, brain and central nervous system, therefore to VOC classes gas detection be very necessary.Currently used VOC
Class gas detection method includes：Gas detection based on multisensor and the gas detection based on infrared image.Based on more sensings
The gas detection of device needs the VOC gas in air to be detected after reaching finite concentration, and a variety of when existing in air
Interference is easily caused during VOC gas between sensor.Gas detection based on infrared image needs manually to operate equipment,
To realize that VOC gas detect.In addition when detecting gas leakage, gas leak position can only be determined by infrared image
Position, and the resolution ratio of general infrared detector is relatively low, is difficult to carry out gas leakage by infrared image when environment is more complicated
Be accurately positioned.

The utility model, which provides one kind, can overcome drawbacks described above, and level of security is high, effective gas leakage easy to use
Detection positioning and warning device.
Leakage inspection positioning provided by the utility model and warning device, it is characterized in that, whole equipment is encapsulated in
In housing, including visible light image sensor, infrared image sensor, laser designator, image data memory and master control core
Piece, the data information memory that main control chip collects visible light image sensor, infrared image sensor is collected enter picture number
According to memory and it is uploaded to PC；Visible light image sensor and laser designator are fixed on switching mechanism, on common housing
Same loophole.
Described main control chip is communicated by wireless sending module and wireless receiving module with PC.
Described switching mechanism includes motor, driving wheel, slide plate, and slide plate be concave shape structure, its base be gear-like and
Driving wheel matches, and driving wheel is rotated by motor driven；Visible ray, infrared image sensor module are separately fixed at the two of slide plate
On vertical edge；
Spacer is provided at both ends with slide plate, spacer connects main control chip.
Described spacer is touch sensor.
Main control chip connects warning device.
The beneficial effects of the utility model are：
Using infrared detection means improve Leakage inspection precision, and combine visible images can directly locating gas let out
Position is leaked, is easy to staff to repair leakage point；One loophole is set on shell, it is safe to use.Detection process is not
Need manually to participate in, and need to only reveal after gas reaches finite concentration in the subrange of leakage, gas can be realized
Detection and alarm, improve gas detection efficiency；One PC can connect more detection devices by wireless transceiver, can be simultaneously
Realize the gas detection work in multiple laboratories.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model：
Fig. 1 is the utility model switching mechanism structural representation；
In figure：1st, driving wheel；2nd, slide plate；3rd, motor；4th, laser designator；5th, visible light image sensor.
Specific embodiment：
Whole equipment as shown in Figure 1 is encapsulated in housing, includes visible light image sensor 5, infrared image sensor, laser
Indicator 4, image data memory and main control chip, main control chip collect visible light image sensor 5, infrared image sensor
The data information memory collected enters image data memory and is uploaded to PC；Visible light image sensor 5 and laser refer to
Show that device 4 is fixed on switching mechanism, same loophole on common housing.
Described main control chip is communicated by wireless sending module and wireless receiving module with PC.
Described switching mechanism includes motor, driving wheel, slide plate, and slide plate be concave shape structure, its base be gear-like and
Driving wheel matches, and driving wheel is rotated by motor driven；Visible light sensor 5 is separately fixed at slide plate 2 with laser designator 4
On two vertical edges；
Spacer is provided at both ends with slide plate 2, spacer connects main control chip.
Described spacer is touch sensor.
Main control chip connects warning device.
Laser designator 4 is made up of for shooting positioning LASER Light Source.Because this equipment is needed under inflammable and explosive environment
Work, its explosion-proof performance can be effectively improved by reducing the perforate of equipment, therefore the utility model is by laser designator and visible ray, red
Outer imaging sensor shares a loophole.Controlled it by switching mechanism, switching construction includes motor, driving wheel, cunning
Piece and spacer.Driving wheel is fixed on the output shaft of motor, is engaged with the driving rack of slide plate bottom, and a left side for slide plate can be achieved
Right motion.In order to ensure that the position of laser designator 4, visible light image sensor 5 and loophole is on same straight line, in cunning
The both ends of piece 2 are provided with spacer, and the preferred feeler of spacer, when vane motion is to spacer position, spacer is sent out
Go out trigger signal and stop the rotation of motor to main control chip, main control chip, complete handoff procedure, and can guarantee that effectively shared same
Individual loophole.
Image data memory is connected with visible ray, infrared image sensor module, and image data memory is used to delay
Deposit view data.During normal detection, infrared image sensor collection image, it corresponds to loophole always, and visible images pass
Sensor does not work, and main control chip reads infrared picture data from image data memory, promoting the circulation of qi physical examination method of determining and calculating of going forward side by side.If inspection
Gas leakage is measured, main control chip starts switching mechanism, it will be seen that optical image sensor module is switched to printing opacity hole site, goes forward side by side
Row IMAQ.And the infrared picture data comprising leakage information and visible images data are carried out by wireless sending module
Send, wireless receiving module receives view data and is saved in PC, and staff can click through according to pictorial information to leakage
Row confirms, to be repaired to leakage point.Meanwhile main control chip startup sends alarm command to warning device, warning device hair
Go out alarm signal.
Above-mentioned case study on implementation is only to understand the utility model example, and is not to the utility model embodiment party
The restriction of formula.To belonging to obvious changes or variations that spirit of the present utility model amplifies out still in the utility model
Protection domain in.
