[0059] The present application provides a control method, system and readable storage medium for a field combustible gas monitoring device. The control method, system and readable storage medium for a field combustible gas monitoring device of the present application are described in detail below in conjunction with the accompanying drawings. The features of the following embodiments and implementations can be combined with each other without conflict.

[0060] The present application provides a control method for a field combustible gas monitoring device, the field combustible gas monitoring device includes a combustible gas monitor, an alarm and a camera, and the control method includes:

[0061] Obtain the combustible gas concentration in the environment monitored by the combustible gas monitor;

[0062] If the combustible gas concentration is greater than the concentration threshold, the alarm is controlled to sound and the combustible gas monitor is controlled to rotate;

[0063] During the rotation of the combustible gas monitor, the combustible gas concentration is obtained multiple times;

[0064] Determine the direction of the combustible gas monitor corresponding to the maximum value among the plurality of combustible gas concentrations;

[0065] Control the camera to rotate to a certain direction and collect image information in the environment.

[0066] Compared with the prior art, the control method of the field combustible gas monitoring device provided by the present application controls the alarm to sound if the combustible gas concentration is greater than the concentration threshold, and controls the combustible gas monitor to rotate, and obtains the combustible gas concentration multiple times during the rotation of the combustible gas monitor. According to the orientation of the combustible gas monitor corresponding to the multiple maximum combustible gas concentration values ​​obtained during the rotation process, the orientation is the direction of the combustible gas leakage. By controlling the camera to rotate to a certain direction, and controlling the camera to collect image information in the environment, the camera can collect image information in the direction of the combustible gas leakage, which is convenient for complete and accurate recording of the combustible gas leakage, improving the integrity and clarity of the monitoring data, and improving the effectiveness of combustible gas monitoring.

[0067] Please refer to Figure 1 , Figure 1The schematic diagram of the structure of a field combustible gas monitoring device 1 shown in an embodiment, the field combustible gas monitoring device 1 includes a tracked vehicle 2, a box 9, a combustible gas monitor 3, an alarm 4 and a camera 5. By setting the tracked vehicle 2, the combustible gas monitoring device 1 can be moved on uneven ground in the field and can bear a large load. The box 9, the combustible gas monitor 3, the alarm 4 and the camera 5 are all arranged on the tracked vehicle 2. The alarm 4 is arranged on the box 9, and the alarm 4 is an audible and visual alarm 4.

[0068] The combustible gas monitor 3 is used to collect the concentration of combustible gas in the environment. The combustible gas monitor 3 is a non-contact combustible gas monitor. The detection principle is the laser absorption spectrum principle. The combustible gas monitor includes a transmitting module and a receiving module. When the combustible gas monitor is working, the transmitting module emits a detection laser of a specific wavelength to the outside. The detection laser will be diffusely reflected when encountering a reflector, and part of the laser will return to the receiving module of the combustible gas monitor. In the light beam path, if there is an air mass formed by a combustible gas leak, the air mass will absorb the detection laser. The ratio of the amount of unabsorbed light to the amount of absorbed light is in a functional proportional relationship with the concentration of the air mass. The concentration of the air mass can be inferred by calculating this ratio.

[0069] exist Figure 1 In the illustrated embodiment, the outdoor combustible gas monitoring device 1 further includes a lifting rod 6, a pan-tilt platform 7, and an anemometer 8. The lifting rod 6 is disposed on the tracked vehicle 2, the pan-tilt platform 7 is disposed on the top of the lifting rod 6, and the combustible gas monitor 3 and the camera 5 are both disposed on the top of the pan-tilt platform 7. The anemometer 8 is disposed on the top of the lifting rod 6 to detect the wind direction and wind speed in the environment. By arranging the lifting rod 6 and the pan-tilt platform 7, the monitoring range of the combustible gas monitor 3 can be increased.

[0070] Please refer to Figure 2 , Figure 2 The present invention is a flowchart of a control method for a field combustible gas monitoring device shown in an embodiment. The control system of the field combustible gas monitoring device provided in the present application is used to execute the control method for the field combustible gas monitoring device. The computer readable storage medium provided in the present application stores a program, and the control method for the field combustible gas monitoring device is implemented when the program is executed.

[0071] The control method of the outdoor combustible gas monitoring device provided in the embodiment of the present application includes steps 21 to 25.

[0072] Step 21, obtaining the concentration of combustible gas in the environment monitored by the combustible gas monitor. Specifically, the concentration of combustible gas in the environment is obtained by the combustible gas monitor.

[0073] Step 22, if the combustible gas concentration is greater than the concentration threshold, the control alarm is sounded, and the combustible gas monitor is controlled to rotate. The concentration threshold is pre-set. If the pipeline for transporting combustible gas is not damaged, the combustible gas is not leaked, and the concentration of combustible gas is less than the concentration threshold. When the pipeline for transporting combustible gas is damaged, the combustible gas leaks, and the combustible gas concentration is greater than the concentration threshold, the control alarm is sounded to remind construction personnel and background monitoring personnel near the pipeline to pay attention and take timely measures.

[0074] Step 23, during the rotation of the combustible gas monitor, the combustible gas concentration is obtained multiple times.

[0075] Step 24, determining the direction of the combustible gas monitor corresponding to the maximum value among the multiple combustible gas concentrations, which direction is the direction of the combustible gas leakage.

[0076] Step 25, controlling the camera to rotate to a certain direction, and controlling the camera to collect image information in the environment.

[0077] The control method of the outdoor combustible gas monitoring device provided in the present application controls the alarm to sound if the combustible gas concentration is greater than the concentration threshold, and controls the combustible gas monitor to rotate, and obtains the combustible gas concentration multiple times during the rotation of the combustible gas monitor. According to the orientation of the combustible gas monitor corresponding to the multiple maximum combustible gas concentration values ​​obtained during the rotation process, the orientation is the direction of the combustible gas leakage. By controlling the camera to rotate to a direction, and controlling the camera to collect image information in the environment, the camera can collect image information in the direction of the combustible gas leakage, which is convenient for complete and accurate recording of the combustible gas leakage situation, improving the integrity and clarity of the monitoring data, and improving the effectiveness of combustible gas monitoring.

[0078] Please refer to Figure 3 , Figure 3 for Figure 2 The flowchart shown is a step 24 of the control method of the field combustible gas monitoring device and an implementation method of the step 24.

[0079] exist Figure 3 In the illustrated embodiment, step 24 controls the rotation of the combustible gas monitor to determine the direction of the combustible gas monitor corresponding to the maximum combustible gas concentration, including steps 241 to 243.

[0080] Step 241, controlling the combustible gas monitor to rotate multiple times, and obtaining the combustible gas concentration multiple times during the rotation process.

[0081] Step 242, determining the direction of the maximum value of the combustible gas concentration in each rotation of the combustible gas monitor.

[0082] Step 243, determining the orientation intervals of the plurality of orientations.

[0083] Step 25 controls the camera to rotate to a direction, including step 251 controls the camera to rotate to a direction range.

[0084] By rotating one circle, the direction of the combustible leak can be determined during the rotation. However, there is a possibility that the leak direction may be inaccurate due to wind direction or the error in the collection of the combustible gas monitor. Figure 3 In the embodiment shown, by controlling the combustible gas to rotate multiple times and determining the direction of the maximum combustible gas concentration in each circle, multiple direction intervals are determined, and the direction interval is determined as the combustible gas leakage interval, which is more accurate. Controlling the camera to rotate to the direction interval and controlling the camera to collect image information in the environment can improve the integrity of the image information in the leakage direction.

[0085] In other embodiments, the control method further includes controlling the camera to rotate within the orientation interval, and collecting image information in the environment during the rotation process. When the field of view of the camera is smaller than the size of the orientation interval, the camera cannot collect a complete image within the orientation interval if it does not rotate. By controlling the camera to rotate within the orientation interval, and collecting image information in the environment during the rotation process, the camera can collect complete image information within the orientation interval.

[0086] Controlling the camera to rotate and collect images includes controlling the camera to record video during the rotation of the camera, or controlling the camera to rotate to a preset angle and then stay for a preset time interval during the rotation of the camera, and controlling the camera to take photos within the preset time interval when the camera stays.

[0087] Please refer to Figure 4 , Figure 4 for Figure 2 The control method step 22 of the field combustible gas monitoring device shown in FIG. Figure 4 In the illustrated embodiment, if the combustible gas concentration is greater than the concentration threshold, step 22 controls the alarm to sound and controls the combustible gas monitor to rotate, including steps 221 to 223.

[0088] Step 221, controlling the combustible gas monitor to rotate multiple circles.

[0089] Step 222, determining the maximum value of the combustible gas concentration when the combustible gas monitor rotates one circle.

[0090] Step 223, controlling the alarm level of the alarm according to the change value of the maximum value of the combustible gas concentration.

[0091] In this way, by controlling the combustible gas monitor to rotate multiple circles to determine the maximum value of the combustible gas concentration at each circle, and analyzing the change value of the maximum value of the combustible gas concentration, the amplitude of the increase in the combustible gas concentration can be obtained, and then the degree of combustible gas leakage can be determined. The alarm level can be controlled according to the degree of combustible gas leakage, and the combustible gas leakage situation can be graded.

[0092] Please refer to Figure 5 , Figure 5 A flow chart of a control method for a field combustible gas monitoring device provided in another embodiment. Figure 5 In the embodiment shown, the control method further includes step 26 of establishing a link between the combustible gas concentration and the image information. Step 26 of establishing a link between the combustible gas concentration and the image information includes steps 261 to 264.

[0093] Step 261, recording the combustible gas concentration and the corresponding monitoring time.

[0094] Step 262: Add a first mark to the combustible gas concentration that is greater than the concentration threshold.

[0095] Step 263, store the image information.

[0096] Step 264 , establishing a link between the combustible gas concentration greater than the concentration threshold and its corresponding image information.

[0097] In some embodiments, the field combustible gas monitoring device includes a storage device, which can be arranged on the combustible gas monitoring device body, and can also be transmitted to an external mobile terminal or a cloud platform through a wireless transmission module arranged on the combustible gas monitoring device. The combustible gas concentration in the environment collected by the combustible gas monitor is stored by the storage device. A first mark is added to the combustible gas concentration greater than the concentration threshold, and the mark can be a text mark or a color mark. For example, the color of the combustible gas concentration not greater than the concentration threshold is set to green, and the color of the combustible gas concentration greater than the concentration threshold is set to red, etc. By storing image information and establishing a link between the combustible gas concentration greater than the concentration threshold and its corresponding image information. It is convenient to view the image information of the leak later, and the concentration information and image information can be traced.

[0098] In some embodiments, the control method further includes step 27 of identifying the image information. Figure 6 , Figure 6 A flow chart of a control method for a field combustible gas monitoring device provided in yet another embodiment. Figure 6 In the illustrated embodiment, step 27 of identifying image information includes step 271 and step 272 .

[0099] Step 271, identifying the image information.

[0100] Step 272: If there is a burning feature or an explosion feature in the image information, a second mark is added to the image, and the alarm level of the alarm is determined.

[0101] Image information is identified to determine whether there are combustion features and explosion features in the image information, which can be obtained by machine learning using a convolutional neural network. If there are combustion features or explosion features in the image information, a second identifier is added to the image, which can be a text annotation or a symbol annotation. According to whether there are combustion features and explosion features in the image information, the alarm level of the control alarm can increase the processing priority of combustion and explosion conditions, and take timely response measures.

[0102] exist Figure 6 In the illustrated embodiment, step 27 also includes steps 273 to 275 .

[0103] Step 273: If there is a leak point feature of a combustible gas leak point in the image information.

[0104] Step 274, controlling the camera to rotate toward the combustible gas leakage point, and collecting image information including the combustible gas leakage point.

[0105] Step 275, controlling the camera to zoom, and controlling the camera to collect image information containing the combustible gas leakage point at different focal lengths.

[0106] The image information is identified and it is determined whether there are leakage point features of a combustible gas leakage point in the image information, which can be obtained by machine learning using a convolutional neural network. If the features of a combustible gas leakage point are identified in the image, the camera is controlled to rotate toward the combustible gas leakage point, and image information containing the combustible gas leakage point is collected. The image information of the combustible gas leakage point can be collected in a targeted manner. By controlling the camera to zoom and controlling the camera to collect image information containing the combustible gas leakage point at different focal lengths, the clarity of the image information of the combustible gas leakage point can be improved.

[0107] like Figure 1 As shown, the combustible gas monitoring device also includes an anemometer 8, a crawler 2, and a GPS positioning system. The anemometer 8, the combustible gas monitor 3, the alarm 4, and the camera 5 are all arranged on the crawler 2, and the GPS positioning system has a built-in map. The control method also includes step 28 to control the movement of the crawler. Please also refer to Figure 7 , Figure 7 A flow chart of a control method for a field combustible gas monitoring device provided in yet another embodiment. Figure 7In the illustrated embodiment, step 28 in the field combustible gas monitoring device control method controls the movement of the tracked vehicle, including steps 281 to 285.

[0108] Step 281, obtaining wind direction information in the environment monitored by the anemometer.

[0109] Step 282, marking the construction scope through the GPS positioning system. The construction scope can be marked on a map built into the GPS positioning system. For example, the construction personnel can determine the longitude and latitude information of the construction scope boundary, and input the longitude and latitude information of the construction scope boundary into the map of the combustible gas monitoring device, and mark the construction scope on the map.

[0110] Step 283, determine the downwind area of ​​the construction range as the target area for the crawler vehicle.

[0111] Step 284, obtaining the current position of the crawler vehicle. Specifically, the current position of the crawler vehicle can be determined by a GPS positioning system.

[0112] Step 285, controlling the crawler vehicle to move from the current position to the target area.

[0113] In this way, the combustible gas monitoring device can be moved to the downwind position of the construction range. If the pipeline within the construction range is damaged during the construction process and a leak occurs, the combustible gas monitor located under the pipeline can sense the change in the concentration of the combustible gas as early as possible, thereby facilitating the timely detection of combustible gas leaks.

[0114] In other embodiments, the control method further includes: obtaining wind direction information monitored in real time. If the wind direction information changes, and the amplitude of the change exceeds the wind direction change limit, and the duration of maintaining the current wind direction exceeds the wind direction maintenance duration limit, the downwind area of ​​the construction opening is determined based on the wind direction information as the target area of ​​the tracked vehicle. The tracked vehicle is controlled to move to the target area. In this way, the position of the combustible gas monitoring device can be adjusted in time according to the change of wind direction, so that the combustible gas monitoring device is located at the downwind position of the construction range.

[0115] Please refer to Figure 8 , Figure 8 A flow chart of a control method for a field combustible gas monitoring device provided in other embodiments, Figure 8 In the illustrated embodiment, after step 285 controls the crawler vehicle to move from the current position to the target area, steps 286 to 288 are also included.

[0116] Step 286, controlling the camera to collect target image information in the environment.

[0117] Step 287, identify and process the target image information to determine the current construction area currently under construction.

[0118] Step 288, controlling the crawler vehicle to move toward the current construction area, and making the distance between the crawler vehicle and the current construction area within a set spacing interval.

[0119] In some embodiments, by analyzing the distribution of construction workers and the actions of construction workers in the image information, the area where construction workers are densely distributed and construction workers are taking construction actions can be identified as the current construction area. The tracked vehicle can be controlled to move toward the current construction area so that the distance between the tracked vehicle and the current construction area is within the set spacing interval. As the construction progresses, when the current construction area changes, the combustible gas monitoring device automatically follows the current construction area. It is convenient to collect the combustible gas concentration in the environment during the construction process, and when the combustible gas concentration exceeds the concentration threshold, collect image information in the environment.
