[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] In this application, terms such as "upper," "lower," "front," "back," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0046] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "installed," "disposed," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0048] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0049] Gas leak detectors, as crucial safety monitoring equipment, play an indispensable role in numerous industries, including the chemical, oil, and natural gas industries. They are primarily used to monitor various gas leaks in real time to ensure the smooth operation of industrial production and various equipment, effectively maintaining overall safety at the production site. However, conventional technologies often rely on manual analysis and interpretation of thermal imaging images captured by the gas leak detector. This process requires personnel to rely on their experience and judgment to identify and locate the specific location of pipeline leaks from complex images.

[0050] However, in densely packed industrial environments with crisscrossing pipelines, this traditional manual location method undoubtedly faces significant challenges. Leaks can be hidden anywhere in dense pipeline networks, and the interplay of pipes and other obstacles complicates the interpretation of information in thermal images. Therefore, manual methods alone are difficult to quickly and accurately locate pipeline leaks, increasing safety risks on the production floor and potentially impacting production efficiency and equipment maintenance.

[0051] In view of this, the present application provides a gas leak detector that can use the RTK positioning module to locate the acquired image of the target pipeline, effectively improve the detection efficiency of pipeline leakage problems, reduce labor costs, and thus improve the safety and reliability of industrial production and equipment operation.

[0052] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0053] See also Figure 1-Figure 3 The embodiment of the present application provides a gas leak detector 100, which includes a housing 1, a camera unit 2 and an RTK positioning module 3. The camera unit 2 is arranged at one end of the housing and is electrically connected to the main board 4. The camera unit 2 is configured to collect images of the target pipe and send them to the main board 4. The RTK positioning module 3 is arranged in the housing 1. The RTK positioning module is electrically connected to the main board 4. The RTK positioning module 3 is configured to output a target positioning signal. The main board 4 is configured to control the RTK positioning module 3 to output a target positioning signal when the camera unit 2 collects an image of the target pipe, so as to obtain an image of the target pipe with position coordinates carried by the target positioning signal. The RTK positioning module 3 is arranged on the main board 4. The RTK positioning module 3 is located between the camera unit 2 and the battery 6, that is, the camera unit 2, the RTK positioning module 3 and the battery 6 are arranged in sequence along the second direction F2 (see Figure 6 ).

[0054] The GNSS (Global Navigation Satellite System) ground-based augmentation system is a crucial component of the satellite navigation system, providing services that enhance positioning accuracy and integrity. It primarily serves ground-based applications such as surveying and mapping, monitoring and control, driver training, precision agriculture, aviation and navigation, and other professional fields, as well as public areas such as transportation navigation, tourism, and emergency rescue. Currently, several service providers in China offer high-precision differential data services for GNSS high-precision RTK (Real Time Kinematic) solutions. User receivers receive base station data from service providers and perform RTK solutions based on differential corrections, improving satellite navigation accuracy. The optimized positioning accuracy can range from millimeters to centimeters. When using differential data services, user receivers report their approximate location. The service provider selects a nearby base station based on the user's location and transmits the base station coordinates and observations to the user via the network. After receiving the base station's position and observation information via the network, the user performs RTK solutions to obtain a definitive position.

[0055] Since the RTK positioning module 3 can achieve centimeter-level positioning accuracy, the main board 4 of the gas leak detector 100 uses the camera unit 2 to capture the image of the target pipeline and controls the RTK positioning module 3 to output the target positioning signal. The main board 4 obtains the image of the target pipeline with the position coordinates carried by the target positioning signal. The inspection personnel can quickly and accurately locate the pipeline leakage point based on the image of the target pipeline with the position coordinates carried by the target positioning signal, thereby effectively improving the detection efficiency of pipeline leakage problems and effectively reducing labor costs, thereby improving the safety and reliability of industrial production and equipment operation.

[0056] In some embodiments, the RTK positioning module 3 includes a signal receiving module 31 and a signal processing module 32. The signal processing module 32 and the signal receiving module 31 are both electrically connected to the mainboard 4. The signal receiving module 31 is configured to receive positioning information and send the positioning information to the signal processing module 32. The signal processing module 32 is configured to determine the position coordinates carried by the target positioning signal based on the positioning information. The positioning information is received by the signal receiving module 31 and sent to the signal processing module 32. The signal processing module 32 processes the obtained positioning information to determine the image of the target pipeline at the position coordinates carried by the target positioning signal, thereby enabling the gas leak detector 100 to accurately locate the pipeline leak point, thereby improving the detection efficiency of the gas leak detector 100, and further improving the safety and reliability of industrial production and equipment operation.

[0057] Optionally, the signal receiving module 31 includes a GNSS antenna 311 and a first communication antenna 312. The GNSS antenna 311 and the first communication antenna 312 are both electrically connected to the mainboard 4. The GNSS antenna 311 is configured to receive a first positioning signal, and the first communication antenna 312 is configured to receive a second positioning signal. The signal processing module 32 is configured to determine the position coordinates carried by the target positioning signal based on the first positioning signal and the second positioning signal. Among them, the first positioning signal and the second positioning signal are both positioning signals carrying positioning information. Since the first positioning signal received by the GNSS antenna 311 is GNSS satellite positioning information, and the second positioning signal received by the first communication antenna 312 is positioning information sent by the base station, the signal processing module 32 performs RTK calculations on the first positioning signal and the second positioning signal to obtain positioning information, thereby achieving accurate positioning of the pipeline leakage point by the gas leak detector 100, thereby improving the detection efficiency of the gas leak detector 100, and further improving the safety and reliability of industrial production and equipment operation.

[0058] Optionally, the GNSS antenna 311 is a helical antenna. The helical antenna is composed of a metal helical wire with good electrical conductivity. Due to its unique helical structure, the GNSS antenna 311 can form a strong radiation field strength in a specific direction, thereby achieving efficient directional transmission capability. At the same time, the GNSS antenna 311 also has a strong impedance matching capability and a wide-band characteristic. The GNSS antenna 311 utilizes the inductive effect and radiation effect of the helical structure to improve the effective radiation and reception of the GNSS antenna 311 within a wide-band range, thereby effectively improving the detection accuracy and detection efficiency of the gas leak detector 100 for finding pipeline leaks. In addition, the GNSS antenna 311 can generate circularly polarized waves, which enables better anti-interference capability when receiving and transmitting signals. In complex environments, circularly polarized waves can more effectively penetrate obstacles and reduce signal loss, thereby improving the detection sensitivity and reliability of the gas leak detector 100.

[0059] Optionally, the first communication antenna 312 may include, but is not limited to, a 2G antenna, a 3G antenna, a 4G antenna, a 5G antenna, a WIFI antenna, a Bluetooth antenna, and the like. The 4G antenna has a relatively short frequency band and strong wall penetration capability, making it well suited for use inside buildings or in scenarios where signals need to be transmitted through obstacles. Furthermore, the 4G antenna also has advantages in long-distance transmission, capable of covering a wider communication area. This allows the use of drones, unmanned vehicles, and the like, instead of on-site inspection personnel, when using the gas leak detector 100, enabling remote inspection of the target pipeline, thereby effectively reducing the labor costs of inspection personnel and improving their operational safety.

[0060] Optionally, the gas leak detector 100 further includes a second communication antenna 5, which is disposed within the housing 1 and electrically connected to the mainboard 4. The second communication antenna 5 is configured to communicate with a terminal device (not shown) to transmit an image of the target pipeline with the location coordinates carried by the target positioning signal to the terminal device. Thus, inspectors can obtain the image and actual location coordinates of the target pipeline through the terminal device, facilitating the precise location of pipeline leaks, thereby improving the detection efficiency of the gas leak detector 100 and, in turn, enhancing the safety and reliability of industrial production and equipment operation.

[0061] It is understood that the second communication antenna 5 is one or more of a Bluetooth antenna, a WiFi antenna, and an NFC (Near Field Communication) antenna. Of course, as other embodiments, the communication connection between the gas leak detector 100 and the terminal device can also be a wired connection, such as an Ethernet connection, a serial port connection, a USB connection, an MBus connection, etc.

[0062] The terminal device includes, but is not limited to, mobile phones, tablet computers, laptop computers, computers, wearable devices (such as smart watches or smart bracelets), drones, robots, digital cameras, smart homes, smart helmets, smart glasses, and other devices with communication functions. The terminal device may also be a handheld device with wireless communication functions, a computing device or other processing device connected to a wireless modem, an in-vehicle device, an electronic device in a 5G network, or an electronic device in a future public land mobile network (PLMN), etc., which is not limited in the embodiments of the present application.

[0063] Please also refer to Figure 3-Figure 5 Optionally, the signal receiving module 31 and the second communication antenna 5 are both arranged at the top of the shell. This can effectively reduce the interference of other components inside the gas leak detector 100 on the signal, such as the radiation generated by the battery 6, the central processing unit, etc., thereby improving the working performance of the signal receiving module 31 and the second communication antenna 5, making the signal receiving and sending capabilities of the signal receiving module 31 and the second communication antenna 5 stronger. In addition, arranging the signal receiving module 31 and the second communication antenna 5 at the top of the shell 1 can reduce the probability of the signal receiving module 31 and the second communication antenna 5 being blocked when the inspector holds the gas leak detector 100, thereby effectively avoiding the transmission and reception of the signal being affected, thereby improving the stability of the signal transmission and reception of the signal receiving module 31 and the second communication antenna 5. It can be understood that the top of the shell 1 is the side of the gas leak detector 100 that is away from the ground in normal use scenarios.

[0064] Please also refer to Figures 2 to 5In some embodiments, the housing 1 includes an upper housing 11, a front housing 12, a lower housing 13, and a rear housing 14. The upper housing 11 and the lower housing 13 are disposed opposite each other along a first direction F1, and the front housing 12 and the rear housing 14 are disposed opposite each other along a second direction F2. The front housing 12, the upper housing 11, the rear housing 14, and the lower housing 13 are sequentially enclosed and connected to form an installation space. This installation space is used to house functional modules of the gas leak detector 100, such as the mainboard 4 and the RTK positioning module 3. The front housing 12 has a first opening 121 that communicates with the installation space. The camera unit 2 includes a visible light module 21 and an infrared camera module 22. The infrared camera module 22 is disposed in the lower housing 13 and at least partially extends out of the first opening 121. The infrared camera unit 2 is configured to capture an infrared image of the target pipeline. The visible light module 21 is disposed adjacent to the infrared camera module 22 and is configured to capture a visible light image of the target pipeline. The mainboard 4 is configured to obtain an image of the target pipeline based on the visible light image and the infrared image of the target pipeline. The second direction F2 intersects with the first direction F1.

[0065] It is understood that the visible light module 21 records and stores visible light images through visible light imaging technology; the infrared camera module 22 is used to capture infrared thermal radiation and convert infrared radiation that is invisible to the naked eye into infrared images that are visible to the naked eye through infrared imaging technology. Among them, the infrared camera module 22 includes an infrared lens 221 and an infrared core module 222. The infrared core module 222 includes an infrared detector, a signal processing circuit, and an image processing circuit. The infrared lens 221 is used to collect infrared radiation from objects and focus it on the infrared detector. The infrared detector then converts the radiation signals of varying strengths into corresponding electrical signals and outputs them to the signal processing circuit. The signal processing circuit then outputs the corresponding electrical signals to the image processing circuit for processing, and finally outputs the corresponding infrared image. As a result, the gas leak detector 100 then processes the obtained infrared image and visible light image to obtain an image of the target pipeline that is convenient for analyzing the gas leak point, thereby improving the detection efficiency of pipeline leakage problems and improving the safety and reliability of industrial production and equipment operation.

[0066] It is understandable that the visible light image can transmit the detection screen to the terminal device through the second communication antenna 5, which is convenient for the detection personnel to review later; the infrared image can also be transmitted to the terminal device through the second communication antenna 5. Exemplarily, the visible light image and the infrared image can be transmitted to the terminal device and then processed by the terminal device to obtain an image of the target pipeline. The image of the target pipeline obtained by processing the visible light image and the infrared image can show both the location of the target pipeline and the diffusion trend of the gas cloud, so that the specific location of the gas leak point can be directly determined from the image of the target pipeline. This achieves rapid identification of the gas leak detection point in the target pipeline, thereby improving the detection efficiency of the gas leak detector 100, and further improving the safety and reliability of industrial production and equipment operation.

[0067] See also Figure 6 Optionally, the gas leak detector 100 further includes a battery 6. The rear housing 14 is formed as a battery compartment 141 having a second opening 1411. The battery 6 is disposed in the battery compartment 141 and electrically connected to the mainboard 4. A compartment cover 61 is provided on the battery 6, and the compartment cover 61 is configured to cover the second opening 1411. The rear housing 14 can form a battery compartment 141 having a second opening 1411, allowing the battery 6 to be disposed in the battery compartment 141 and electrically connected to the mainboard 4. This effectively simplifies the overall appearance of the gas leak detector 100 and improves the integrity of the housing 1 of the gas leak detector 100. Furthermore, the compartment cover 61 is provided on the battery 6. When the battery 6 is disposed in the battery compartment 141, the compartment cover 61 can cover the second opening 1411 of the battery compartment 141, allowing the battery 6 to be completely concealed within the gas leak detector 100, thereby effectively improving the overall appearance of the gas leak detector 100. Furthermore, setting the compartment cover 61 on the battery 6 can simplify the operating steps of the inspector. For the insertion and removal of the battery 6, only one step is required, which is to take out the battery 6 or insert the battery 6, without the need to open the compartment cover 61, then take out the battery 6, or insert the battery 6 and then close the compartment cover 61. This design can also effectively reduce the possibility of losing the compartment cover 61.

[0068] Optionally, the gas leak detector 100 further includes an image-finding module 7, which is electrically connected to the main board 4. The rear shell 14 further includes a third opening 142, and the image-finding module 7 is passed through the third opening 142 to extend out of the shell 1. The image-finding module 7 can display the real-time image of the visible light module 21 to the inspector, helping the inspector to clearly observe the object during the shooting process, thereby accurately framing the target pipeline. In addition, the image-finding module 7 can prevent interference from external strong light, so that in outdoor or strong light environments, the inspector can still clearly see the shooting picture through the image-finding module 7. Among them, the image-finding module 7 can be a viewfinder.

[0069] Please refer again Figure 2Optionally, the housing 1 further includes a first side housing 15 and a second side housing 16, and the first side housing 15 and the second side housing 16 cover both sides of the installation space along the third direction F3. The gas leak detector 100 further includes a display screen 8, which is electrically connected to the mainboard 4. The display screen 8 is rotatably connected to the first side housing 15 or the second side housing 16, and the display screen 8 is configured to display an image of the target pipeline with the position coordinates carried by the target positioning signal. The third direction F3 intersects with the first direction F1 and the second direction F2. If the display screen 8 is rotatably connected to the first side housing 15 or the second side housing 16, the display screen 8 can be rotated to the side facing the inspector during use, making it easier for the inspector to view the image of the target pipeline with the position coordinates carried by the target positioning signal, thereby enabling the gas leak point to be accurately located on the gas leak detector 100. Alternatively, the display screen 8 can be covered with the first side housing 15 or the second side housing 16 when not in use, so that the screen of the display screen 8 faces the first side housing 15 or the second side housing 16 instead of being exposed to the outside, so that the screen of the display screen 8 can be effectively protected, thereby increasing the service life of the gas leak detector 100. The display screen 8 can be a touch screen, a liquid crystal display, etc.

[0070] Optionally, the gas leak detector 100 further includes a gripping portion 9, which is provided on the side of the housing 1 opposite to the setting position of the display screen 8. The inspector can grasp and control the gas leak detector 100 through the gripping portion 9, thereby controlling the shooting position and shooting angle of the gas leak detector 100 on the target pipeline. In addition, the gripping portion 9 is provided on the side of the housing 1 opposite to the setting position of the display screen 8, so that while holding the gas leak detector 100, the other hand can perform touch operations on the display screen 8, thereby facilitating the inspector's use of the gas leak detector 100 and improving the user experience. Of course, as another embodiment, the gripping portion 9 can also be provided at the bottom of the gas leak detector 100, which can also achieve the above-mentioned purpose, and this application does not limit this.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
