DETAILED DESCRIPTION

[0024] The application provides a field combustible gas monitoring device. The field combustible gas monitoring device of the application is described in detail below in combination with the drawings.

[0026] By arranging the controller, the data terminal module and the wireless communication module, the data terminal module is connected with the combustible gas monitor and is used to collect the concentration information of the combustible gas monitor.

The data is stored and analyzed by the external terminal device, the cost of arranging data processing and data storage devices of the field combustible gas monitoring device is reduced, and the intensive level of field combustible gas monitoring is improved.

[0027] Please refer to Figure 1 and Figure 2 , Figure 1 a control principle block diagram of the field combustible gas monitoring device 1 shown in an embodiment, Figure 2 a perspective structural schematic diagram of the field combustible gas monitoring device 1 shown in an embodiment. In Figure 1 and Figure 2In the shown embodiment, the field combustible gas monitoring device 1 comprises a tracked vehicle 10, a combustible gas monitor 20 arranged on the tracked vehicle 10, an alarm 30, a controller 40, a data terminal module 41 and a wireless communication module 42. The data terminal module 41 and the controller 40 are connected with the wireless communication module 42, the data terminal module 41 is connected with the combustible gas monitor 20 for collecting concentration information of the combustible gas monitor 20, and communicates with an external terminal device 43 through the wireless communication module 42. The controller 40 is connected with the alarm 30 for communicating with the external terminal device 43 through the wireless communication module 42 and controlling the alarm 30.

[0028] By arranging the tracked vehicle 10, the field combustible gas monitoring device 1 can walk on the uneven ground in the field and can bear a large weight. By arranging the controller 40, the data terminal module 41 and the wireless communication module 42, the data terminal module 41 is connected with the combustible gas monitor 20 for collecting concentration information of the combustible gas monitor 20. The controller 40 is connected with the alarm 30 for controlling the alarm 30. The controller 40 and the data terminal module 41 communicate with the external terminal device 43 through the wireless communication module 42. The concentration information of the combustible gas in the environment collected by the combustible gas monitor 20 can be sent to the external terminal device 43 for storage and analysis, and the analysis result of the external terminal device 43 is sent to the controller 40 through the wireless communication module 42, and the controller 40 controls the alarm 30 according to the analysis result of the external terminal device 43. For example, if the concentration of the combustible gas in the environment is greater than a set concentration threshold, the external terminal device 43 sends an instruction to control the alarm 30 to the controller 40, so that the alarm 30 alarms to remind the staff on the construction site.

[0029] The pipeline monitoring unit can provide the field combustible gas monitoring device 1 to the construction staff on the construction site, so that the construction staff transports the field combustible gas monitoring device 1 to the vicinity of the construction site. During the construction process, the field combustible gas monitoring device 1 monitors the concentration of the combustible gas in the environment in real time. If the pipeline is damaged during the construction process to cause the combustible gas to leak, the field combustible gas monitoring device 1 timely sends an alarm information to remind the staff on the construction site to handle it in time to avoid the risk from expanding. If the road near the construction site is uneven and the vehicle cannot reach there, the field combustible gas monitoring device 1 can walk to the parking position through the tracked vehicle 10.

[0030] The personnel of the pipeline monitoring unit can not have to arrive at the site for whole-process monitoring, but can achieve whole-process monitoring through remote control, realize visualization of monitoring data and traceability of monitoring data, and improve the informatization level of monitoring. The data is uniformly stored and analyzed by the external terminal device 43, which reduces the cost of setting data processing and data storage devices of the field combustible gas monitoring device 1 and improves the intensive level of field combustible gas monitoring.

[0031] In some embodiments, the external terminal device 43 is a mobile terminal such as a mobile phone or a tablet computer. In other embodiments, the external terminal device 43 is a non-mobile control platform such as an industrial computer. One external terminal device 43 can control multiple field combustible gas monitoring devices 1 at the same time, which can save labor costs and improve monitoring efficiency.

[0032] The combustible gas monitoring device 1 further comprises a box 11 arranged on the top of the tracked vehicle 10. The controller 40, the data terminal module 41, and the wireless communication module 42 are all arranged in the box 11. The box 11 provides a housing space for the controller 40, the data terminal module 41, and the wireless communication module 42, and protects the controller 40, the data terminal module 41, and the wireless communication module 42.

[0033] When the concentration of the combustible gas in the environment is greater than the set concentration threshold, the external terminal device 43 not only sends an instruction to the controller 40 to control the alarm 30 to alarm, reminding the staff on the construction site, but also sends an alarm instruction by itself, such as vibration, ringing, voice broadcast to remind the monitoring personnel beside the external terminal device 43 to pay attention, and can also send information to a preset designated address or make a phone call. The sent information can be a short message or a prompt message sent through a public number platform, which reminds the background monitoring personnel to pay attention through various means, and takes measures in time.

[0034] Please refer to Figure 2 and Figure 3 , Figure 3 The control principle block diagram of the field combustible gas monitoring device 1 is shown in another embodiment. In the embodiment shown in Figure 3 The combustible gas monitoring device 1 further comprises a lifting rod 50 arranged on the top of the tracked vehicle 10, and the combustible gas monitor 20 is arranged on the top of the lifting rod 50. By arranging the lifting rod 50, and the lifting rod 50 can be lifted relative to the tracked vehicle 10, which facilitates the combustible gas monitor 20 on the top of the lifting rod 50 to be arranged at a higher position, thereby improving the monitoring range of the combustible gas monitor 20.

[0035] The combustible gas monitoring device 1 further comprises a holder 52 arranged on the top of the lifting rod 50. The combustible gas monitor 20 is arranged above the holder 52, and the holder 52 can rotate to improve the monitoring range of the combustible gas monitor 20. The holder 52 is connected with the controller 40. When the concentration of the combustible gas in the environment exceeds the set threshold, the external terminal device 43 not only sends a command to the controller 40 through the wireless communication module 42 to control the alarm 30 to alarm, but also sends a command to the controller 40 through the wireless communication module 42 to control the holder 52 to rotate, so that the holder 52 stops in a certain time interval or in the direction of the combustible gas leakage when rotating. In this way, the change of the combustible gas concentration can be analyzed.

[0036] The top end of the lifting rod 50 is provided with a range finder 53 for measuring the height of the lifting rod 50. The data terminal module 41 is connected with the range finder 53 for collecting the height information of the range finder 53 and sending it to the external terminal device 43 through the wireless communication module 42. The external terminal device 43 combines the expected height information and the height information of the range finder 53 to generate a lifting instruction. The controller 40 is connected with the lifting rod 50 for controlling the lifting rod 50 to lift according to the lifting instruction of the external terminal device 43.

[0037] The lifting rod 50 comprises a rod body and a driving member arranged at the bottom of the rod body and drivingly connected with the rod body. The controller 40 is connected with the driving member for controlling the driving member to drive the rod body to lift. The lifting rod 50 can be a pneumatic lifting rod or a hydraulic lifting rod. When the lifting rod 50 is a pneumatic lifting rod, the driving member comprises an air pump. When the lifting rod 50 is a hydraulic lifting rod, the driving member comprises a hydraulic device. The present application does not limit this.

[0038] The lifting rod 50 can not only be remotely controlled by the external terminal device 43, but also be controlled on site beside the combustible gas monitoring device 1. Figure 2 and Figure 3 In the embodiment shown in the figure, the lifting rod 50 further comprises a manual control switch 51 connected with the controller 40. The controller 40 is used to control the driving member to drive the rod body to lift when the manual control switch 51 is triggered, thereby improving the convenience of controlling the lifting rod 50.

[0039] Because the lifting rod 50 can lift, the height of the combustible gas monitor 20 arranged at the top of the lifting rod 50 can be adjusted. During the lifting process of the lifting rod 50, the combustible gas monitor 20 is connected with the data terminal module 41. In some embodiments, the combustible gas monitoring device 1 further comprises a connecting line 60 and a cable winding and unwinding disc rotatably arranged on the tracked vehicle 10. The connecting line 60 is wound on the cable winding and unwinding disc. The combustible gas monitor 20 is connected with the data terminal module 41 through the connecting line 60. The cable winding and unwinding disc rotates to wind or release the connecting line 60 during the lifting process of the lifting rod 50.

[0040] Specifically, during the ascent of the boom 50, the cable reel rotates in either a clockwise or counterclockwise direction to release the connecting cable 60, increasing its length in the lifting direction of the boom 50. During the descent of the boom 50, the cable reel rotates in the opposite direction (clockwise or counterclockwise) to wind up the connecting cable 60, decreasing its length in the lifting direction of the boom 50. This prevents the connecting cables 60 from piling up and affecting the lifting of the boom 50 or the movement of the tracked vehicle 10.

[0041] Please refer to this again. Figure 2 ,exist Figure 2 In the illustrated embodiment, the combustible gas monitoring device 1 further includes a connecting cable 60 and a cable storage bin 61 located on the tracked vehicle 10. The connecting cable 60 is a spiral cable, and the combustible gas monitor 20 is connected to the data terminal module 41 via the connecting cable 60. The cable storage bin 61 is used to store the connecting cable 60. The connecting cable 60 is coiled or straightened during the lifting and lowering process of the lifting rod 50 to change its length in the lifting and lowering direction. Specifically, during the lifting rod 50's ascent, the connecting cable 60 is straightened, increasing its length in the lifting and lowering direction; during the lifting rod 50's descent, the connecting cable 60 is coiled, decreasing its length in the lifting and lowering direction.

[0042] Spiral cables, also known as helical cables or flexible cables, feature a spiral design. Spiral cables offer good flexibility and resilience, making them suitable for environments requiring frequent movement. The spiral structure allows the cable to maintain its shape and structure under tension and compression, preventing tangling or damage. When unstretched, spiral cables are relatively short, saving space; when stretched, they are longer, allowing connection between two devices over longer distances.

[0043] The combustible gas monitoring device 1 also includes a camera 70. A controller 40 is connected to the camera 70 and is used to control the camera 70 to collect image information from the environment. The camera 70 is connected to a data terminal module 41 and is used to send image information to an external terminal device 43 through the data terminal module 41 and a wireless transmission module. Furthermore, the image information collected by the camera 70 can be stored in the external terminal device 43 for later review, enabling traceability of image information during monitoring and improving the authenticity and effectiveness of the monitoring.

[0044] Specifically, when the concentration of the combustible gas in the environment is greater than the set concentration threshold, the external terminal device 43 sends an instruction to the controller 40 to control the camera 70 to collect image information in the environment, and the controller 40 controls the camera to collect image information in the environment. By controlling the camera 70 to collect image information in the environment, the background personnel can more intuitively perceive the situation on site, such as the natural environment, facility situation, personnel situation and oil and gas pipeline situation of the site. For example, whether there are construction personnel on site, the density of buildings and facilities around the site, whether the site has collected response measures, whether the response measures are effective, whether there is a burning situation on site, etc., so as to facilitate the monitoring personnel to take targeted response measures.

[0045] In some embodiments, the wireless communication module 42 is a 5G communication module, and the wireless communication module 42 includes a communication card slot for inserting a communication card. The download and upload speed provided by the 5G network is significantly higher than that of the 4G, which can reach 10Gbps or even higher. The delay of 5G can be as low as milliseconds, which can achieve faster response. In other embodiments, the wireless communication module 42 can also be a 4G communication module, which can provide higher speed and lower delay, and can be used in places without 5G network coverage.

[0046] In some embodiments, the data terminal module 41 is a DTU module, and the data terminal module 41 includes a memory card slot for inserting a memory card. By setting the memory card slot for inserting the memory card, the data generated during the operation of the combustible gas monitoring device 1, log files and configuration information can be stored, ensuring that the data will not be lost due to accidental power failure or network failure. Data backup and local data viewing can also be performed, and in the event of a fault, the memory card can be quickly removed for data analysis to help locate the problem. Because the data is stored in the external terminal device 43 setting, the memory card can be set with a memory overwrite period, which reduces the capacity of the memory card while meeting the need to view recent monitoring conditions.

[0047] In some embodiments, the tracked vehicle 10 includes a control handle for controlling the movement of the tracked vehicle 10 on site. The controller 40 is also connected to the tracked vehicle 10 for controlling the movement of the tracked vehicle 10 through the external terminal device 43. The combustible gas monitoring device 1 also includes a wind direction instrument 54 for obtaining wind direction information in the environment, the wind direction instrument 54 is connected to the data terminal module 41 and transmits the wind direction information to the external terminal device 43 through the data terminal module 41 and the wireless transmission module. The external terminal device 43 controls the camera to collect image information in the construction environment through the controller 40, obtains the position of the oil and gas pipeline according to the image information, and controls the tracked vehicle 10 to move to the downwind position of the oil and gas pipeline through the external terminal device 43 according to the wind direction information and the position information of the oil and gas pipeline. In this way, the combustible gas monitor 20 can collect the concentration of combustible gas in the environment.

[0048] Referring now to the drawings Figure 2 and Figure 4 , Figure 4 As Figure 4 As shown in another embodiment, a control principle block diagram of the field combustible gas monitoring device 1. The field combustible gas monitoring device 1 further comprises an emergency switch 80 connected between the wireless communication module 42 and the controller 40, for disconnecting the controller 40 and the wireless communication module 42. When the field combustible gas monitoring device 1 moves to the target position and starts to detect the concentration of combustible gas in the environment, the emergency switch 80 can be closed at this time, the wireless communication module 42 and the controller 40 are connected, the controller 40 can receive the instructions of the external terminal device 43 through the wireless communication module 42 to control the field combustible gas monitoring device 1.

[0049] When there are network anomalies or external terminal device 43 anomalies causing control instructions disorder, or combustible gas leakage causing the construction site to appear fire and explosion, etc., by operating the emergency switch 80 to disconnect the controller 40 and the wireless communication module 42, at this time, the field combustible gas monitoring device 1 is no longer controlled by the remote terminal, and the site construction personnel controls the track vehicle 10 to drive away from the site through the control handle, improving the rapidity of evacuation.

[0050] In some embodiments, the emergency switch 80 comprises a first emergency switch 81 and a second emergency switch 82, and the first emergency switch 81 and the second emergency switch 82 are connected in series. Disconnecting any one of the first emergency switch 81 and the second emergency switch 82 can disconnect the controller 40 and the wireless communication module 42. The track vehicle 10 comprises a travel direction and a non-travel direction perpendicular to the travel direction, and the track vehicle 10 comprises a first side and a second side opposite in the non-travel direction, the first emergency switch 81 is located on the first side, and the second emergency switch 82 is located on the second side. In this way, the first emergency switch 81 and the second emergency switch 82 are respectively located on both sides of the non-travel direction of the track vehicle 10, and the first emergency switch 81 and the second emergency switch 82 can be operated during the movement of the track vehicle 10, and the controller 40 and the wireless communication module 42 can be disconnected in time. Avoiding the adverse consequences caused by remote control errors or remote slow.
