Description

Technical Field

[0001] This utility model belongs to the field of methane detection technology and relates to a vehicle-mounted roof-mounted laser methane telemetry gimbal system. Background Technology

[0002] Different gases absorb light with different spectral lines and intensities. Based on this principle, a laser methane telemetry instrument emits a laser beam towards the target being detected. The deflected light reflected back from the target is received by the laser methane telemetry instrument. By analyzing and calculating the changes in the light signal, the concentration information of methane can be obtained.

[0003] Urban gas pipelines are intricate and complex, and existing gas leak detection methods have the following problems: First, installing pan-tilt-zoom laser methane remote detectors on fixed poles at stations limits coverage due to the fixed location of the detectors, and the equipment is also relatively complex and costly. Second, inspectors manually patrol along roads using handheld laser methane remote detectors, which is labor-intensive, inefficient, and unable to detect leaks promptly. Furthermore, handheld laser methane remote detectors typically transmit data via Bluetooth, usually only displaying the maximum and average methane concentration of the detected target, making it difficult to view real-time images of the target. This limits the information available to inspectors and fails to adequately meet practical needs.

[0004] Therefore, it is evident that the structure of existing laser methane telemetry instruments needs further improvement. Utility Model Content

[0043] Example:

[0044] like Figure 1 As shown, the vehicle-mounted roof-mounted laser methane telemetry gimbal system in this embodiment includes a methane telemetry device 1, a camera 2, an electric gimbal device 5, and a WiFi module 6.

[0045] Among them, the methane telemetry device 1 is used to collect methane concentration information, and the camera 2 is used to collect real-time monitoring images of the area detected by the methane telemetry device 1. The methane telemetry device 1 and the camera 2 are mounted on the electric pan-tilt device 5.

[0046] The electric pan-tilt unit 5 is mounted on the inspection vehicle 3 and can adjust the data acquisition angle of the methane telemetry device 1 and the camera 2 by rotating itself. The methane telemetry device 1 and the camera 2 are integrated into the housing of the electric pan-tilt unit 5. Its new mechanical structure is more flexible and convenient than the previous pan-tilt devices that were fixed on the field pole. It can also be mounted on the inspection vehicle 3 to perform mobile detection of gas pipeline leaks. It has a lower cost, reduces the workload of inspection personnel, and improves the efficiency of urban gas pipeline inspection.

[0047] WiFi module 6 is used for remote data transmission and control. Methane telemetry device 1 is connected to camera 2 via signal connection. The motorized pan-tilt unit 5 and camera 2 are connected to WiFi module 6 via composite cable 7. WiFi module 6 communicates wirelessly with remote terminal device 4. Remote terminal device 4 is a smart terminal device equipped with a WiFi module. Control commands issued by remote terminal device 4 control the rotation of the casing of motorized pan-tilt unit 5, thereby changing the sampling angle of methane telemetry device 1 and camera 2. This achieves unified adjustment of the detection direction, avoiding inconsistencies between the directions of methane telemetry device 1 and camera 2, which would affect the accuracy of the detection results.

[0048] like Figure 2 As shown, the methane telemetry device 1 includes a temperature control drive board 11, a laser detection unit 12, a signal amplification board 13, a signal processing board 14, and a control board 15.

[0049] The control board 15 is the control center of the methane telemetry device 1. The control board 15 is equipped with a power supply and is electrically connected to the temperature control drive board 11, the laser detection unit 12, the signal amplification board 13 and the signal processing board 14 respectively. The control board 15 controls the above components to perform functions and to conduct data communication.

[0050] The temperature control drive board 11 is controlled by the control board 15 and is used to control the operating temperature of the laser detection unit 12 and provide drive current.

[0051] The laser detection unit 12 is used to emit and receive the reflected detection laser. The laser detection unit 12 includes a laser, a main mirror, and a photodiode. The temperature control drive board 11 is electrically connected to the laser. When the temperature control drive board 11 provides a driving current to the laser, the laser emits a detection laser towards the area to be detected. The laser reflected back from the target is received by the main mirror. After the photodiode converts the optical signal into an electrical signal, it is transmitted to the signal amplification board 13.

[0052] The newly converted electrical signal is very weak. The signal amplifier board 13 is used to amplify and filter the signal. The analog signal is converted into a digital signal by the analog-to-digital converter chip and then transmitted to the signal processing board 14.

[0053] The signal processing board 14 is used to calculate the received digital signal and obtain the methane concentration value of the laser irradiation area.

[0054] The control board 15 is equipped with a microcontroller and is connected to the camera module 2 via signal transmission. The camera 2 is connected to the WiFi module 6 via a composite cable 7. The signal processing board 14 transmits the calculated methane concentration data back to the microcontroller on the control board 15. The control board 15 then transmits the methane concentration data to the camera module 2. The camera module 2 integrates the methane concentration data output by the methane telemetry device 1, the image information and location information monitored by the camera 2, and other data, and transmits them to the WiFi module 6 via the composite cable 7.

[0055] Furthermore, camera 2 is preferably a 360° surround-view camera to monitor the inspection environment from all angles. The camera module of camera 2 is preferably a Hikvision module, and in this embodiment, the camera module of camera 2 also includes a positioning module for locating the current detection area. Control board 15 transmits methane concentration data to the camera module of camera 2 via the 485 protocol. The camera module of camera 2 converts the methane concentration information collected by methane telemetry device 1, the image information monitored by camera 2, and the location information collected by the positioning module into network information, and then transmits it to WiFi module 6 via composite cable 7.

[0056] In addition, the composite cable 7 includes a power supply cable and a signal cable. The power supply cable provides power to the WiFi module 6, and the signal cable is used to transmit network data and control commands.

[0057] The methane concentration information collected by the methane telemetry device 1, the image information monitored by the camera 2, and the location information collected by the positioning module are transmitted to the WiFi module 6 via a signal cable, and then wirelessly transmitted to the remote terminal device 4 via the WiFi module 6. Control commands issued by the remote terminal device 4 are wirelessly transmitted to the WiFi module 6, and then transmitted to the motorized pan-tilt device 5 via a signal cable. This utility model's methane telemetry pan-tilt system uses the WiFi module 6 and composite cable 7 to achieve remote data transmission and control, facilitating maintenance and providing testing personnel with richer information such as real-time monitoring images to better meet practical needs.

[0058] In this embodiment, the WiFi module 6 is preferably a router, and the remote terminal device 4 is preferably a smart tablet. The smart tablet is wirelessly connected to the router and is used to receive and display detection information, including methane concentration information collected by the methane telemetry device 1, image information monitored by the camera 2, and location information collected by the positioning module. The smart tablet is also used for human-computer interaction, issuing control commands to control the operation of the methane telemetry device 1 and the camera 2. Of course, the aforementioned remote terminal device 4 is not limited to a smart tablet and can also be a smartphone or other smart terminal device.

[0059] In addition, the vehicle-mounted roof-mounted laser methane telemetry PTZ system of this embodiment also includes an alarm device 8, which is signal-connected to the remote terminal device 4.

[0060] Alarm device 8 is preferably a buzzer. The smart tablet determines the methane risk level of the detection area based on the received methane concentration information. If the methane gas concentration is greater than the set alarm threshold, the smart tablet will sound an alarm and the buzzer will ring. The current real-time monitoring screen and location information are stored in the smart tablet's memory, which makes it convenient for monitoring personnel to accurately find the leak point and deal with it based on the real-time monitoring screen and location information.

[0061] In this embodiment, the process of the vehicle-mounted roof-mounted laser methane telemetry gimbal system detecting leaks in urban gas pipelines is as follows:

[0062] Schedule inspection tasks using a smart tablet;

[0063] The inspectors sit in the inspection vehicle 3 to inspect the road surface where the pipeline is buried. The smart tablet issues instructions, which are transmitted to the electric pan-tilt device 5 via the WiFi module 6 and the composite cable 7 to control the methane telemetry device 1 and the camera 2.

[0064] Under the control of the control board 15, the temperature control drive board 11 provides driving current to the laser, and the laser of the laser detection unit 12 emits detection laser to the detection area. The laser reflected back from the detection target is received by the main mirror and processed by the photodiode, the signal amplification board 13 and the signal processing board 14 in sequence to obtain the methane concentration information.

[0065] The methane concentration information collected by the methane telemetry device 1, the image information monitored by the camera 2, and the location information collected by the positioning module are transmitted to the smart tablet via the WiFi module 6.

[0066] The inspectors check the detection data on the smart tablet. If there are any abnormalities, they further check the real-time monitoring screen and location information of the corresponding location of the problem point. Subsequently, the staff will handle the gas leak point. If there are no abnormalities, the inspection will continue until all target areas have been inspected and the inspection will end.

[0067] The present embodiment has now been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the vehicle-mounted roof-mounted laser methane telemetry gimbal system of this utility model. Of course, the above description is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made using the content of this utility model's specification and drawings under the inventive concept of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model and should be protected by this utility model.
