TECHNICAL FIELD

[0001] The present application relates to the technical field of combustible gas detection, and in particular to a combustible gas leakage detection method, system and computer device. BACKGROUND

[0002] Combustible gas detection refers to preventing combustion or explosion caused by combustible gas meeting fire source or electric spark and the like energy after the combustible gas reaches a certain concentration by detecting the concentration of combustible gas in air. At present, when detecting the leakage of combustible gas from a pipeline, such as a pipeline transporting natural gas, to a user, combustible gas concentration sensors are usually installed at positions prone to leakage of the pipeline, or personnel of a gas company check along the gas pipeline to detect whether combustible gas leaks. Neither installing combustible gas concentration sensors nor checking along the gas pipeline can detect the whole pipeline in real time. SUMMARY

[0003] In order to detect the whole pipeline in real time, the present application provides a combustible gas leakage detection method, system and computer device.

[0004] In a first aspect, the present application provides a combustible gas leakage detection method, which adopts the following technical scheme:

[0005] A combustible gas leakage detection method comprises:

[0006] Real-time acquisition of detection signals sent by each combustible gas concentration sensor; wherein the combustible gas concentration sensor reciprocally slides in a corresponding detection area, the length of a gas pipeline laid at a user is pre-acquired, and the pipeline length is equally divided into N detection areas based on the pipeline length;

[0007] Judgment of whether each detection signal is abnormal;

[0008] If there is an abnormal signal, an alarm information is sent to a user mobile terminal and a gas company terminal; wherein the alarm information contains position information of an abnormal combustible gas concentration sensor.

[0009] By adopting the technical scheme, since the length of the pipeline is acquired in advance, the pipeline is equally divided into N detection areas, and the combustible gas concentration sensor reciprocally slides in each detection area, so that the entire pipeline can be detected, and since the combustible gas concentration sensor reciprocally slides in the detection area, the pipeline can be detected in real time, so that the combustible gas concentration sensor can realize real-time detection of the entire pipeline. When the signal sent by the combustible gas concentration sensor corresponding to a detection area is abnormal, it indicates that the detection area may leak, so alarm information is sent to the user mobile terminal and the gas company terminal, so that the user and the gas company can know, and the position of the abnormal combustible gas concentration sensor can be determined according to the alarm information, and the position of the detection area can be quickly located.

[0010] Optionally, after the alarm information is sent, the method further comprises:

[0011] acquiring a highest leakage concentration in the abnormal detection area;

[0012] controlling the abnormal combustible gas concentration sensor to stop at the highest leakage concentration.

[0013] By adopting the technical scheme, the highest leakage concentration in the abnormal detection area is likely to be the pipeline leakage point, so the combustible gas concentration sensor is controlled to stop at the highest leakage concentration, so that the maintenance personnel can quickly locate the leakage point.

[0014] Optionally, the detection method further comprises:

[0015] During initial detection, the combustible gas concentration sensor is located at the beginning of the corresponding detection area, and all the combustible gas concentration sensors move synchronously;

[0016] When an abnormality occurs in a detection area, the combustible gas concentration sensors in the remaining normal detection areas move synchronously;

[0017] After the abnormal detection area is normal, all the combustible gas concentration sensors are located at the beginning of the corresponding detection area.

[0018] By adopting the technical scheme, since the combustible gas concentration sensors corresponding to the normal detection areas move synchronously, the control logic can be avoided.

[0019] Optionally, the detection method further comprises:

[0020] acquiring a moving duration of the combustible gas concentration sensor;

[0021] judging whether the moving duration reaches a preset moving duration threshold;

[0022] If yes, send a prompt information to the user mobile terminal;

[0023] Based on the prompt information, the moving time is prolonged.

[0024] By adopting the above technical solution, if the prompt information is received, it indicates that the combustible gas concentration sensor moving time reaches the moving time threshold, and the power source driving the combustible gas concentration sensor to move needs to be replaced, so that the power source can be replaced in time to prolong the moving time.

[0025] Optionally, the detection method further comprises:

[0026] Obtaining the number of abnormal detection areas;

[0027] Based on the number of abnormal detection areas, determining the leakage level;

[0028] If the number of abnormal detection areas exceeds half, the leakage level is level three;

[0029] If the number of abnormal detection areas is more than half of half to half, the leakage level is level two;

[0030] If the number of abnormal detection areas is less than half of half, the leakage level is level one; level one to level three represent more and more serious.

[0031] By adopting the above technical solution, the leakage level can be determined according to the number of abnormal detection areas, so that the corresponding repair scheme can be formulated according to the leakage level, and the repair efficiency is improved.

[0032] Optionally, after determining the leakage level, the method comprises:

[0033] If the leakage level is above level two, send a protection information to the user mobile terminal and the gas company terminal;

[0034] Send a cleaning information to the user mobile terminal.

[0035] By adopting the above technical solution, if the leakage level is above level two, it indicates that the leakage is relatively serious, so the protection information needs to be sent to the user mobile terminal and the gas company terminal to prompt the user and the repair personnel to take protection and improve the safety; the purpose of sending the cleaning information is to prompt the user to clean the surrounding combustible materials in time, and further improve the safety.

[0036] In a second aspect, the application provides a combustible gas leakage detection system, which adopts the following technical solution:

[0037] A combustible gas leakage detection system comprises:

[0038] The combustible gas concentration sensor is distributed and reciprocally slides in a corresponding detection area, the length of a gas pipeline laid at a user is acquired in advance, and the pipeline length is equally divided into N detection areas based on the pipeline length;

[0039] The signal acquisition module is configured to acquire detection signals sent by each combustible gas concentration sensor in real time.

[0040] The judgment module is configured to judge whether each detection signal is abnormal.

[0041] The information sending module is configured to send alarm information to a user mobile terminal and a gas company terminal when there is an abnormal signal, wherein the alarm information includes position information of an abnormal combustible gas concentration sensor.

[0042] According to the above technical scheme, the length of the pipeline is acquired in advance, the pipeline is equally divided into N detection areas, and the combustible gas concentration sensor reciprocally slides in each detection area, so that the entire pipeline can be detected. Since the combustible gas concentration sensor reciprocally slides in the detection area, the pipeline can be detected in real time, so that the combustible gas concentration sensor can be detected in real time. When the judgment module judges that the signal sent by the combustible gas concentration sensor corresponding to a detection area is abnormal, it means that the detection area may leak. Therefore, the information sending module sends alarm information to the user mobile terminal and the gas company terminal, so that the user and the gas company can know the position of the abnormal combustible gas concentration sensor and quickly locate the position of the detection area.

[0043] Optionally, the detection system further comprises:

[0044] The auxiliary pipe is sleeved on the outside of the gas pipeline.

[0045] The auxiliary rack is fixedly connected to the inner wall of the auxiliary pipe.

[0046] The auxiliary gear is the same number as the number of detection areas, and is engaged with the auxiliary rack.

[0047] The driving motor is powered by a battery, and the output shaft is coaxially fixedly connected with the auxiliary gear.

[0048] The connecting block is rotatably connected with the auxiliary gear, and the combustible gas concentration sensor is mounted on the connecting block.

[0049] By controlling the forward and reverse rotation of the driving motor, the auxiliary gear can reciprocally move along the auxiliary rack, so that the combustible gas concentration sensor can reciprocally detect along the pipeline.

[0050] Thirdly, this application provides a computer device that adopts the following technical solution:

[0051] A computer device, comprising:

[0052] A memory for storing the aforementioned combustible gas leak detection program;

[0053] The processor is used to execute the program stored in the memory to implement the steps of the above-described combustible gas leak detection method.

[0054] Fourthly, this application provides a computer-readable storage medium, which adopts the following technical solution:

[0055] A computer-readable storage medium storing a computer program that can be loaded by a processor and executed as described above for detecting combustible gas leaks.

[0056] In summary, this application has at least the following beneficial effects:

[0057] 1. By obtaining the length of the pipeline in advance and dividing the pipeline into N detection areas according to the length of the pipeline, and deploying a reciprocating combustible gas concentration sensor in each detection area, real-time detection of the entire pipeline can be achieved.

[0058] 2. By controlling the abnormal combustible gas concentration sensor to stop at the point of highest leakage concentration, it is easier for maintenance personnel to quickly locate the leak point.

DETAILED DESCRIPTION

[0070] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Figure 1 -Appendix Figure 9 , the technical scheme in the embodiments of the present application is clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0071] The embodiments of the present application disclose a combustible gas leakage detection method. Referring to Figure 1 , as an implementation of the detection method, the detection method can include S110-S130:

[0072] S110, real-time acquisition of detection signals sent by each combustible gas concentration sensor; wherein the combustible gas concentration sensor reciprocatingly slides in the corresponding detection area, the length of the gas pipeline laid at the user is acquired in advance, and based on the pipeline length, it is equally divided into N detection areas;

[0073] S120, judging whether each detection signal is abnormal;

[0074] S130, if there is an abnormal signal, sending an alarm information to the user mobile terminal and the gas company terminal; wherein the alarm information contains the position information of the abnormal combustible gas concentration sensor.

[0075] Specifically, the gas pipeline can be equally divided into N detection areas according to a preset partition rule after the entire length of the gas pipeline is input into the user, wherein the equal division is for an even number m of the gas pipeline, if the gas pipeline is an odd number m, the remaining distance is a detection area alone after the gas pipeline is equally divided into an even number m; for example, the gas pipeline is 10 m, and the partition rule is 2 m as a detection area, so the gas pipeline is equally divided into 5 detection areas; if the gas pipeline is 11 m, the gas pipeline is equally divided into 5 detection areas, and the last 1 m is the 6th detection area. Each combustible gas concentration sensor is driven by an independent power source, which is a battery-powered motor-related mechanism.

[0076] The detection signal anomaly refers to the gas concentration value detected by the combustible gas concentration sensor exceeding the threshold value; the sensor is an abnormal combustible gas concentration sensor, and the corresponding detection area is an abnormal detection area. In addition, a positioning module is installed on the combustible gas concentration sensor for real-time positioning of the sensor position. The user mobile terminal can be a smart phone, a smart wearable device, etc. of the user; the gas company terminal can be a monitoring computer in the gas company, or a mobile terminal of a maintenance personnel, etc.

[0077] Referring to Figure 2 After sending the alarm information, S140-S150 can be further included:

[0078] S140, obtaining the highest leakage concentration in the abnormal detection area;

[0079] S150, controlling the abnormal combustible gas concentration sensor to stop at the highest leakage concentration.

[0080] Specifically, since the combustible gas concentration sensor is provided with a positioning module, after the detection area is abnormal, the abnormal combustible gas concentration sensor is controlled to stop at the highest leakage concentration, so that the maintenance personnel can quickly locate the leakage point.

[0081] It should be noted that during the initial detection, the combustible gas concentration sensor is located at the beginning of the corresponding detection area, and all the combustible gas concentration sensors move synchronously; when an abnormality occurs in a certain detection area, the combustible gas concentration sensors in the remaining normal detection areas move synchronously; the combustible gas concentration sensor in the abnormal detection area stays at the highest leakage concentration. After the abnormal detection area is normal (after the maintenance is completed), all the combustible gas concentration sensors are located at the beginning of the corresponding detection area, and start to move synchronously again.

[0082] Referring to Figure 3 As another embodiment of the detection method, the detection method can further include S210-S240:

[0083] S210, obtaining the moving duration of the combustible gas concentration sensor;

[0084] S220, determining whether the moving duration reaches a preset moving duration threshold;

[0085] S230, if yes, sending a prompt information to the user mobile terminal;

[0086] S240, prolonging the moving duration based on the prompt information.

[0087] Specifically, through the pre-test of the power source, it is known that the total duration that the combustible gas sensor can move after the power is completely consumed, the moving duration threshold is close to the total duration, for example, the difference between them is 10 min. When the combustible gas concentration sensor starts to move, timing is performed, so as to obtain the moving duration of the sensor; further, the moving duration is determined, if it is determined that the moving duration reaches the moving duration threshold, a prompt information is sent to the user mobile terminal; prolonging the moving duration means replacing the power source battery or charging the power source battery.

[0088] Referring to Figure 4 As another embodiment of the detection method, the detection method can further include S310-S320:

[0089] S310, obtaining the number of abnormal detection areas;

[0090] S320, determining the leakage level based on the number of abnormal detection areas.

[0091] Specifically, if the number of abnormal detection areas exceeds half, the leakage level is level three; if the number of abnormal detection areas is more than half to half of the total detection areas, the leakage level is level two; if the number of abnormal detection areas is less than half of the total detection areas, the leakage level is level one; level one to level three represent more and more serious; for example, there are 5 abnormal detection areas and 10 total detection areas, the leakage level is level two; if there are 11 total detection areas, the leakage level is also level two; if there are 21 total detection areas, the leakage level is level one, which is below half of half; if there are 9 total detection areas, the leakage level is level three.

[0092] In addition, referring to Figure 5 After determining the leakage level, S330-S340 can be further included:

[0093] S330, if the leakage level is above level two, sending a protection information to the user mobile terminal and the gas company terminal;

[0094] S340, sending a cleaning information to the user mobile terminal.

[0095] Specifically, if the leakage levels are different, the protection information can also represent different meanings; the protection information contains a preset processing scheme associated with the leakage levels. The cleaning information represents the cleaning of the nearby combustible materials.

[0096] The implementation principle of the embodiment is as follows:

[0097] Real-time detection signals sent by each combustible gas concentration sensor are acquired, and it is determined whether each detection signal is abnormal. If there is an abnormal signal, an alarm information is sent to a user mobile terminal and a gas company terminal, and the highest leakage concentration in the abnormal detection area is acquired, and the abnormal combustible gas concentration sensor is controlled to stop at the highest leakage concentration. The combustible gas concentration sensors in the remaining normal detection areas move synchronously. During the movement of the combustible gas concentration sensor, the movement duration of the combustible gas concentration sensor is acquired, and it is determined whether the movement duration reaches a preset movement duration threshold. If yes, a prompt information is sent to the user mobile terminal, and the movement duration is extended based on the prompt information. The number of abnormal detection areas is acquired, and a leakage level is determined based on the number of abnormal detection areas. If the leakage level is above the second level, a protection information is sent to the user mobile terminal and the gas company terminal, and a cleaning information is sent to the user mobile terminal.
