In view of the above-mentioned problems, the utility model proposes a kind of new gas-detecting device based on infrared image, the devices
By switching the optical filter of different wave length and combining the detection of gas detection algorithm completion multiple gases.
Multiple gases detection and warning device provided by the utility model based on infrared image, it is characterized in that, including
Infrared optical lens, infrared image sensor set optical filter to switch between infrared optical lens and infrared image sensor
Device；Main control chip is further included, main control chip collects the data of infrared image sensor.
The switching device of optical fiber includes driven wheel and driving wheel, and driving wheel is driven by servomotor, servomotor
It is controlled by main control chip, driving wheel drives driven wheel to rotate；Multiple through holes are provided on driven wheel, various optical filterings are set in through hole
Piece.
Main control chip connection memory module, display module, alarm module and the power module.
The beneficial effects of the utility model are：
The utility model can realize a variety of different-waveband gases using infrared detection means combination switching device of optical fiber
Detection, adds the type and quantity of detection gas, improves detection efficiency；Switching device of optical fiber is driven using motor, and
Turntable is positioned using luminous tube and reception pipe, improves the positioning accuracy of optical filter；Image comprising leakage information is protected
There are on the mobile memories such as SD card, convenient for acquisition of the staff to the image containing leakage information；After gas leakage is detected,
Just alarm signal is sent, staff is notified to carry out maintenance, improves gas detection efficiency.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
Fig. 1 is the utility model structure diagram；
In figure：1st, driving wheel；2nd, driven wheel；3rd, optical filter；4th, infrared optical lens；5th, infrared image sensor.
Specific embodiment
The device as shown in Figure 1 includes infrared optical lens 4, infrared image sensor 5, switching device of optical fiber, master control
Chip, optical filter switching key, memory module, LCD display module, warning device and power module.
Wherein switching device of optical fiber is different by switching between infrared optical lens 4 and infrared image sensor 5
Optical filter 3 can gather the infrared image of different-waveband.Memory module is used to cache infrared picture data.Main control chip and storage
Module is connected, and reads image data therein, completes gas using gas detection algorithm and detects；Switched simultaneously according to optical filter
The selection of button, and complete filter plate switching, data storage and send the control work such as alarm signal.Optical filter switching key
The main switching for completing triggering filter plate.Memory module can also be used for the preservation of the picture comprising leakage information.LCD display module
It is mainly used for the infrared image of display acquisition.Warning device is mainly used for sending alarm signal when having detected gas leakage.
Power module is each module for power supply.
In order to realize the automatic switchover of optical filter, driving wheel 1 and driven wheel 2, driven wheel 2 are included in switching device of optical fiber
Through hole is equipped with, the quantity of through hole is determined by the quantity of optical filter 3.Servomotor drives driving wheel to rotate.Servomotor turns
It is dynamic to be controlled by main control chip.In order to improve the positioning accuracy of optical filter 3 so that infrared optical lens, optical filter and infrared
Imaging sensor is in a straight line, and the surface of the utility model each through hole on driven wheel 2 is equipped with loophole, red
Installation luminous tube in corresponding height position directly over outer optical lens, while the corresponding height position directly over infrared image sensor
Reception pipe is installed.When reception pipe receives the signal that luminous tube is sent, illustrate infrared optical lens, optical filter and infrared image
Sensor is in a straight line, and stops motor at this time and rotates.
Specific detection process is as follows：
(1) open equipment and carry out Image Acquisition, and by image data caching in a storage module.
(2) after the completion of two field picture caching, main control chip reads the image data in image data memory, and utilizes
Detection algorithm is detected.
(3) if gas leakage is not detected, by optical filter switching key, the switching of optical filter is completed.It is cut in optical filter
Whether main control chip detection reception pipe receives luminous tube and sends infrared signal during changing, when detecting that reception pipe receives red
After external signal, illustrate that infrared optical lens, optical filter and infrared image sensor are in a straight line, main control chip is sent out at this time
Go out to stop motor and rotate order, motor stalls.
(4) after the completion of optical filter switching, other leakages are detected the presence of again, if gas leakage is not detected, are cut again
Optical filter is changed, if detecting gas leakage, the image data comprising leakage information is saved in memory module by main control chip.
Main control chip control warning device sends 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 the spiritual changes and variations that derived from of the utility model still in the utility model
Protection domain in.
