Description

Technical Field

[0001] The utility model belongs to the field of analyzing materials by optical means, and particularly relates to a gas cloud spectrum analyzer. Background Technique

[0002] There is a risk of natural gas leakage underground. Since the main component of natural gas is methane, methane is a colorless and odorless gas under standard conditions and is not easily detected by workers. However, when the methane in the air reaches a certain concentration, it is prone to explosion, causing safety accidents. Therefore, it is necessary to monitor the methane concentration.

[0003] The Chinese patent application with the publication number CN 104697716 A and the publication date of June 10, 2015 discloses a methane gas leak detection infrared imager. The methane gas leak detection infrared imager includes a housing, an infrared focal plane detector and an infrared lens located on the housing, an infrared image acquisition preprocessing and enhancement processing module (i.e., an image processing module) located inside the housing, a liquid crystal display screen, and an infrared band-pass filter device sheet (equivalent to a filter), etc. The infrared lens, the infrared band-pass filter device sheet and the infrared focal plane detector together constitute an infrared camera.

[0004] When using the above methane gas leak detection infrared imager, the weak difference between the infrared radiation of the methane gas and the infrared radiation of the surrounding background is collected by the infrared camera, and the image is processed by the infrared image acquisition preprocessing and enhancement processing module and output to the liquid crystal display screen, so that the leakage condition and leakage position of the methane gas can be seen on the liquid crystal display screen.

[0005] However, in the above methane gas leak detection infrared imager, only the image processed by the infrared image acquisition preprocessing and enhancement processing module can be seen on the liquid crystal display screen. When the worker is looking for the methane leakage position in the processed image, it is necessary to restore the processed image to the on-site image in the brain, that is, it is necessary to analyze and judge by combining the original image on the site in the brain, resulting in a slower speed for the worker to find the methane leakage position. At this time, the methane is still leaking, which further leads to a greater potential safety hazard and a higher risk factor when eliminating the safety hazard.

[0006] By replacing the infrared band-pass filter device sheet, the above methane gas leak detection infrared imager can also be used for imaging the leakage of dangerous gases such as ethane gas, propane gas, and sulfur hexafluoride. A wireless transmission module can also be added to the gas leak detection infrared imager, which facilitates the communication between the gas leak detection infrared imager and the host computer in other places and transmits the image of the gas leak detection infrared imager to the host computer. When eliminating the potential safety hazards of the leakage of dangerous gases such as ethane gas, propane gas, and sulfur hexafluoride, there is also a problem that the speed of the staff looking for the leakage location is slow, resulting in a relatively high risk factor when eliminating the potential safety hazards. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a gas cloud spectrum analyzer to solve the technical problem that only the processed image is displayed on the liquid crystal display of the existing gas leak detection infrared imager. When the staff is looking for the leakage location of dangerous gases facing the processed image, they need to restore the processed image to the on-site image in their brains, resulting in a slow speed when the staff is looking for the leakage location of dangerous gases. At this time, the dangerous gas is still leaking, which further leads to a relatively high risk factor when eliminating the potential safety hazards.

[0008] To achieve the above purpose, the technical solution of the gas cloud spectrum analyzer provided by the present utility model is as follows:

[0009] A gas cloud spectrum analyzer includes a housing and an infrared camera, a display screen, and an image processing module installed on the housing. The image processing module processes the data collected by the infrared camera and transmits the processed image to the display screen. A visible light camera for shooting the same area as the infrared camera is also installed on the housing. Both the visible light camera and the infrared camera are used for forward shooting. The visible light camera is used to transmit the captured image to the display screen to be displayed on the display screen simultaneously with the processed image.

[0010] Furthermore, the display screen is arranged on the side surface of the housing adjacent to the front end surface of the housing.

[0011] Furthermore, a display screen cover for protecting the display screen is also provided on the housing.

[0012] Furthermore, the display screen cover is installed on the housing in a guiding and moving manner along the up-down direction or the left-right direction, so that the operator can open and close the display screen cover through a flat-pushing operation.

[0013] Furthermore, both the visible light camera and the infrared camera are installed inside the housing, and through holes for the shooting ends of the visible light camera and the infrared camera to expose are respectively provided on the front end surface of the housing.

[0014] Furthermore, a main board is also provided inside the housing. The image processing module is arranged on the main board, and at least one interface for communicating with the host computer is also arranged on the side wall of the housing and connected to the main board.

[0015] Furthermore, a main board is also provided inside the housing. The image processing module is arranged on the main board, and at least one of the interactive interface, external display interface, audio interface, and power interface connected to the main board is also arranged on the side wall of the housing.

[0016] Furthermore, each interface is arranged inside an interface box, and the interface box is configured with a corresponding protective cover.

[0017] Furthermore, a lens cover for protecting the infrared lens of the infrared camera is also provided on the housing.

[0018] Furthermore, a mounting base for externally connecting a tripod is provided at the bottom of the housing.

[0019] The beneficial effects of the present utility model are as follows: The present utility model is an improved invention. The visible light camera can capture images that are exactly the same as those seen by the human eye. By simultaneously setting a visible light camera and an infrared camera, after the image processing module processes the image of the infrared camera, the processed image and the image of the visible light camera are simultaneously displayed on the display screen for the staff to observe the processed image and the on-site image on the display screen at the same time. Therefore, when the staff is looking for the leakage location of the dangerous gas, it is not necessary for the staff to restore the processed image to the on-site image in the brain, but directly observe the two images on the display screen and compare them to obtain the leakage location of the dangerous gas. Therefore, the staff can conveniently and quickly find the leakage location of the dangerous gas, thus quickly eliminating potential safety hazards and reducing the risk factor of the staff when eliminating potential safety hazards.

Detailed implementation mode

[0026] The following further describes the present utility model in detail in conjunction with embodiments.

[0027] In the present utility model, a visible light camera refers to a camera that can capture an image exactly the same as the image seen by the human eye.

[0028] Specific embodiment 1 of the gas cloud spectrum analyzer provided by the present utility model:

[0029] The purpose of this embodiment is to provide a gas cloud spectrum analyzer that can facilitate the staff to quickly find the leakage location of dangerous gases and reduce the risk of the staff when eliminating potential safety hazards.

[0030] In this embodiment, as an implementation method, as Figures 1-4 shown, the gas cloud spectrum analyzer includes a housing 4 and an infrared camera 15, a display screen 18 installed on the housing 4, and an image processing module that processes the data collected by the infrared camera 15 and transmits the processed image to the display screen 18. A visible light camera 3 for photographing the same area as the infrared camera 15 is also installed on the housing 4. The visible light camera 3 is used to transmit the captured image to the display screen 18 for display together with the processed image. To prevent dust from falling into the housing 4, the housing 4 includes a housing body and a cover 1 located above the housing body. In this embodiment, the method of processing images using the infrared camera 15 and the image processing module is the same as the method of processing images in the methane gas leak detection infrared imager with the application publication number CN104697716 A and the application publication date of June 10, 2015.

[0031] The visible light camera 3 can capture images that are exactly the same as those seen by the human eye. By setting the visible light camera 3 and the infrared camera 15 simultaneously, after the image processing module processes the image of the infrared camera 15, the processed image and the image of the visible light camera 3 are simultaneously displayed on the display screen 18 for the staff to observe the processed image and the on-site image on the display screen 18 at the same time. Thus, when the staff is looking for the leakage location of the dangerous gas, there is no need for the staff to restore the processed image to the on-site image in the brain, but directly observe the two images on the display screen 18, and obtain the leakage location of the dangerous gas by comparison. Therefore, the staff can conveniently and quickly find the leakage location of the dangerous gas, thereby quickly eliminating potential safety hazards and reducing the risk factor of the staff when eliminating potential safety hazards.

[0032] For the convenience of the staff to observe, as a specific implementation manner, both the visible light camera 3 and the infrared camera 15 are used for forward shooting, and the display screen 18 is arranged on the side surface of the housing adjacent to the front end surface of the housing. Specifically, both the visible light camera 3 and the infrared camera 15 are installed inside the housing 4, and through holes for the shooting ends of the visible light camera 3 and the infrared camera 15 to expose are respectively arranged on the front end surface of the housing. However, in other specific implementation manners, the visible light camera 3 and the infrared camera 15 can also be arranged on the top, bottom or side of the outside of the housing 4, still for forward shooting. At this time, there is no need to set through holes on the front surface of the housing; the display screen 18 can also be arranged at the rear end or the top of the housing 4.

[0033] Installing the visible light camera 3 and the infrared camera 15 inside the housing 4 and respectively arranging through holes for the shooting ends of the visible light camera 3 and the infrared camera 15 to expose on the front end surface of the housing does not require setting additional installation structures, has a simple structure, and saves installation space. Arranging the display screen 18 on the side surface of the housing adjacent to the front end surface of the housing, when the staff is looking for the leakage location of the dangerous gas, they can observe the image on the display screen 18 and the on-site environment by turning their heads, which is convenient for the staff to confirm the leakage location of the dangerous gas.

[0034] To protect the display screen 18, as a specific implementation manner, such as Figure 1As shown, a display screen cover 5 for protecting the display screen 18 is further provided on the housing 4. The display screen cover 5 is installed on the housing 4 with guiding movement in the up and down direction, that is, the display screen cover 5 and the housing 4 are movably matched in the up and down direction, so that the operator can open and close the display screen cover 5 through a flat-pushing operation. Specifically, slide rails and sliding grooves can be respectively arranged on the housing 4 and the display screen cover 5, so that the display screen cover 5 and the housing 4 are slidably matched in the up and down direction; alternatively, sliders and sliding grooves can be respectively arranged on the housing 4 and the display screen cover 5, so that the display screen cover 5 and the housing 4 are slidably matched in the up and down direction; or guide rails and rollers can be respectively arranged on the housing 4 and the display screen cover 5, so that the display screen cover 5 and the housing 4 are rollably matched in the up and down direction. In this embodiment, the manner of the up and down movable match between the display screen cover 5 and the housing 4 is not limited, as long as the display screen cover 5 can move up and down along the housing 4 to expose or cover the display.

[0035] In other specific embodiments, the display screen cover 5 is installed on the housing 4 with guiding movement in the left and right direction, that is, the display screen cover 5 and the housing 4 are movably matched in the left and right direction, so that the operator can open and close the display screen cover 5 through a flat-pushing operation. The manner of the movable match between the display screen cover 5 and the housing 4 can refer to the manner of the up and down movable match between the display screen cover 5 and the housing 4 as described above.

[0036] By providing the display screen cover 5, it can be ensured that the display screen 18 is not polluted by the underground mine environment when the display screen 18 is not in use. Making the display screen cover 5 open and close up and down or left and right (that is, being guided to move in the up and down direction or left and right direction with the housing 4 to expose or cover the display screen 18), on the one hand, the structure is simple and it is convenient to open or close the display screen cover 5; on the other hand, compared with the rotary opening and closing, it can avoid the collision between the display screen cover 5 and the display.

[0037] Of course, in other specific embodiments, the display screen cover 5 can also be hinged on the housing 4 to achieve rotary opening and closing. Or, like in the methane gas leak detection infrared imager mentioned in the background art, the display can be hinged on the housing 4, and the use state and non-use state of the display are switched by rotating the display.

[0038] Of course, in other specific embodiments, the display screen cover 5 can also not be provided, and the display screen can be protected from damage by pasting a tempered film on the display screen.

[0039] Specific embodiment 2 of the gas cloud spectrum analyzer provided by the present utility model:

[0040] The purpose of this embodiment is to provide a gas cloud spectrum analyzer that can be conveniently connected to a host computer outside the mine.

[0041] In this embodiment, as a specific implementation, as Figures 1-4 shown, on the basis of the specific embodiment 1 of the gas cloud spectrum analyzer, a main board 14 is further provided in the housing 4, the image processing module is arranged on the main board 14, and at least one interface (i.e., communication interface) for communicating with the upper computer is arranged on the side wall of the housing 4 and connected to the main board 14. By setting the communication interface, remote communication can be realized, and the image of the accident site can be transmitted to the upper computer, so that the image can be displayed on the upper computer, enabling the remote staff in the command center to guide the on-site staff to operate.

[0042] Specifically, the communication interface can be one kind, two kinds, three kinds or more kinds. Of course, for non-complex situations, the communication interface may not be provided on the main board 14, and only the on-site staff need to handle the leakage of dangerous gases.

[0043] Due to the complex underground conditions, therefore, the communication interface is at least two kinds. As Figure 2 shown, the communication interface has four kinds, namely RS485 interface 7, CAN interface 8, optical fiber interface 10 and RJ45 interface 11. However, in other specific implementation manners, the communication interface can also be two kinds, three kinds or more kinds. By increasing the types of communication interfaces, it can be ensured that in various underground situations, there is always a communication interface that can be used to ensure that the on-site image can be transmitted to the upper computer at the command center.

[0044] To facilitate the control of the gas cloud spectrum analyzer, as a specific implementation, as Figures 1-4 shown, an interaction interface for externally connecting a keyboard to control the gas cloud spectrum analyzer is arranged on the main board 14. However, in other specific implementation manners, the display screen 18 can also be set as a touch screen to control the gas cloud spectrum analyzer through the touch screen; or, a Bluetooth receiving device is arranged on the main board 14 to control the gas cloud spectrum analyzer through a Bluetooth keyboard; or the gas cloud spectrum analyzer is controlled through a mobile phone software, etc. In this embodiment, the control method of the gas cloud spectrum analyzer is not limited, as long as the gas cloud spectrum analyzer can be controlled.

[0045] Through the interaction interface, it is convenient to control the gas cloud spectrum analyzer by using an external keyboard. The interaction interface is generally a USB interface 12, but it can also be a Type-C interface, etc. when adapting to some special keyboards.

[0046] As a specific implementation, a video interface connected to the main board 14 is further arranged on the side wall of the housing 4. Through the video interface, an external display can be connected, so that the image can be displayed on the external display. The video interface can be a VGA interface, an HDMI interface 13, a DP interface or a Type-C interface, etc., as long as the video signal can be output to the external display.

[0047] Additionally, an audio interface 6 connected to the main board 14 is also provided on the side wall of the housing 4, so as to output the sound of the gas cloud spectrometer to an external display or to an additional speaker.

[0048] As a specific implementation manner, a power interface 9 connected to the main board 14 is also provided on the side wall of the housing 4. Through the power interface 9, an external power supply can be connected, so that there is no need to set a battery inside the housing 4, effectively reducing the volume of the housing 4. However, in other specific implementation manners, a battery can also be built into the housing 4.

[0049] To facilitate power connection, a power board 17 is also provided inside the housing 4. The power board 17 is mainly responsible for intrinsically safe voltage conversion, thus facilitating the connection of an external power supply and eliminating the need for an additional power adapter.

[0050] To protect the interfaces, as a specific implementation manner, on the basis of the specific implementation manner with interfaces in this embodiment, each interface is provided in an interface box, and the interface box is configured with a corresponding protective cover. Through the protective cover and the interface box, it can be ensured that the interfaces are not damaged during transportation and do not get dusty when not in use.

[0051] Of course, in other specific implementation manners, when the gas cloud spectrometer is used in an environment with less dust such as indoors, the interface box and the protective cover can be not set.

[0052] To avoid damage to the infrared lens during transportation, as a specific implementation manner, on the basis of the specific embodiment 1 of the gas cloud spectrometer, a lens cover 2 for protecting the infrared lens of the infrared camera 15 is also provided on the housing 4. Through the lens cover 2, the infrared lens can be protected from being damaged during transportation. Specifically, the infrared lens is protected from friction.

[0053] Of course, in other specific implementation manners, the lens cover 2 can also be not set. During transportation, flexible materials such as sponge or foam paper can be laid around the gas cloud spectrometer to avoid damage to the infrared lens.

[0054] To facilitate the fixation of the gas cloud spectrometer, as a specific implementation manner, on the basis of the specific embodiment 1 of the gas cloud spectrometer, a mounting base 16 for connecting to an external tripod is provided at the bottom of the housing 4. Through the mounting base 16, the gas cloud spectrometer can be conveniently fixed.

[0055] Of course, in other specific implementation manners, the mounting base 16 can also be not set. The gas cloud spectrometer can be directly held by hand, or placed on a table or other countertops. Of course, legs can also be provided at the bottom of the housing 4 to facilitate placing the gas cloud spectrometer on a table or other countertops.

[0056] In the present utility model, by replacing the filter in the infrared camera 15, the gas cloud spectral analyzer can detect the leakage of dangerous gases such as methane gas, ethane gas, propane gas, and sulfur hexafluoride.

[0057] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative labor, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
