Description

Technical Field

[0001] This application relates to the field of gas pipeline technology, and in particular to a method, apparatus, equipment and medium for detecting gas pipeline systems. Background Technology

[0002] Urban commercial complexes are buildings that integrate two or more functions, such as shopping, accommodation, exhibitions, catering, entertainment, and transportation hubs. In recent years, the number of large-scale commercial complexes has been increasing year by year, as has the proportion of catering users within them. Frequent changes in shop functions have led to the partial demolition, sealing, and reconstruction of gas pipeline systems. Urban commercial complexes have a large number of gas pipeline users and correspondingly a large number of pipelines. Although gas alarm control systems are installed, many existing systems have undergone demolition, alteration, and new construction. To achieve aesthetic requirements, gas risers are often installed in vertical shafts or between glass curtain walls and the building structure, while horizontal main pipes are mostly installed within suspended ceilings. Therefore, gas leaks can easily cause safety accidents.

[0003] Currently, gas alarm control systems commonly suffer from issues such as gas concentration detection probes exceeding their service life without timely replacement, decreased sensitivity, and malfunctioning gas-sensitive components. These problems prevent the timely detection of gas leaks. Furthermore, renovations and changes in shop functions create new enclosed spaces where existing gas concentration detection probes cannot cover the area, and the lack of newly installed probes creates blind spots, leading to undetected gas leaks and increasing the risk of accidents. Additionally, users often only turn off gas appliances when stopping gas use, failing to detect even minor leaks in the pipeline. This allows small leaks to continue leaking gas for extended periods, resulting in higher gas concentrations near the leak point and a risk of explosion.

[0004] Therefore, the problems existing in the current technology still need to be solved and optimized. Summary of the Invention

[0005] The purpose of this application is to at least partially solve one of the technical problems existing in the related art.

[0075] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. The step numbers in the following embodiments are set only for ease of explanation, and there is no limitation on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0076] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0077] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0078] Currently, gas alarm control systems commonly suffer from issues such as gas concentration detection probes exceeding their service life without timely replacement, decreased sensitivity, and malfunctioning gas-sensitive components. This results in gas leaks not being detected promptly. Furthermore, renovations and changes in shop functions create new enclosed spaces where existing gas concentration detection probes cannot cover the area, and the lack of newly installed probes further exacerbates the problem, leading to undetected leaks and increasing the risk of accidents that endanger lives and property. Additionally, when gas leaks are not detected promptly, the gas concentration near the leak point is often high, posing a risk of explosion.

[0079] In view of this, embodiments of the present invention provide a detection method for a gas pipeline system. This detection method can effectively compensate for the gas leak detection blind spots caused by the failure of gas-sensitive elements and the incomplete coverage of gas concentration detection probes in gas alarm control systems. It can promptly detect gas leaks in pipelines and control the amount of gas leaks, effectively reducing the occurrence of safety accidents.

[0080] Specifically, refer to Figure 1, Figure 2 and Figure 3 In this embodiment of the application, a method for detecting a gas pipeline system is provided, the gas pipeline system comprising:

[0081] Riser 10, horizontal main pipe 9, branch pipe 8, first valve 1, second valve 2, third valve 3, first pressure gauge 4, second pressure gauge 5, third pressure gauge 6, first controller 7, main controller and platform;

[0082] One end of the branch pipe 8 is connected to the first end of the horizontal main pipe 9, and the second end of the horizontal main pipe 9 is connected to the first end of the riser pipe 10.

[0083] The first valve 1 is located at one end of the branch pipe 8, the second valve 2 is located at the second end of the horizontal main pipe 9, and the third valve 3 is located at the second end of the riser pipe 10.

[0084] The first pressure gauge 4 is used to detect the pipeline pressure of the branch pipe 8, the second pressure gauge 5 is used to detect the pipeline pressure of the horizontal main pipe 9, and the third pressure gauge 6 is used to detect the pipeline pressure of the riser pipe 10.

[0085] The first controller 7 is connected to the first valve 1 and the first pressure gauge 4, and the first controller 7 is remotely connected to the main controller;

[0086] The main controller is remotely connected to the second pressure gauge 5, the second valve 2, the third pressure gauge 6, the third valve 3, and the platform;

[0087] It is understandable that the first valve 1 can be used to control the connection status of the branch pipe 8, the first valve 1 and the second valve 2 can be used to control the connection status of the horizontal main pipe 9, and the second valve 2 and the third valve 3 can be used to control the connection status of the riser pipe 10.

[0088] The detection method includes:

[0089] Step 110: The first controller 7 responds to the user's first instruction, generates a valve closing instruction, and executes a first task and a first pressure task in sequence according to the valve closing instruction. The first execution result of the first task is transmitted to the main controller, and the first pressure data of the first pressure task is uploaded to the platform. The first task is the task process of the first controller 7 controlling the first valve 1 to close, and the first pressure task is the task process of the first controller 7 controlling the first pressure gauge 4 to detect the pipeline pressure of the branch pipe 8.

[0090] In some embodiments, step 110, in which the first controller 7 performs a first task according to the valve closing command, includes:

[0091] Step 111: The first controller 7 transmits the valve closing command to the first valve 1, and the first valve 1 executes the valve closing command;

[0092] Step 112: After the valve closing command is executed, the first execution result is generated and transmitted to the first controller 7.

[0093] It is understood that the first controller 7 can obtain the information through the user's action of closing the gas appliance. In this embodiment, specifically, after a gas user in an urban commercial complex stops using gas, the gas user can send a first command to the first controller 7 through the gas appliance's shut-off button. After receiving the first command from the gas user, the first controller 7 generates a valve-closing command and transmits the valve-closing command to the first valve 1. After receiving the valve-closing command, the first valve 1 executes it. When the state of the first valve 1 is fully closed, the first valve 1 ends the valve-closing process and generates a first execution result, which is then transmitted to the first controller 7. Subsequently, the first controller 7 transmits the first execution result to the main controller.

[0094] It is understood that the user can issue the first command to the first controller 7 in various ways, such as through wireless communication or wired communication. This application does not impose any restrictions on this method, as long as it meets the actual needs. Furthermore, the first execution result includes the current status information of the first valve 1, whether the valve is normally open / closed, and the execution time.

[0095] In some embodiments, step 110, the first stress task, includes:

[0096] Step 113: The first controller 7 generates a first pressure detection command based on the first execution result and transmits the first pressure detection command to the first pressure gauge 4;

[0097] Step 114: The first pressure gauge 4 acquires the first data and the second data according to the first time in the first pressure detection instruction, wherein the first time is used to characterize the time interval between acquiring the first data and the second data, the first data is the pressure data detected by the branch pipe 8 in the first detection, and the second data is the pressure data detected by the branch pipe 8 in the second detection.

[0098] Step 115: The first pressure gauge 4 combines the first data and the second data into the first pressure data and then transmits it to the first controller 7.

[0099] It is understandable that after receiving the first execution result from the first valve 1, the first controller 7 can generate a first pressure detection command based on the received first execution result and transmit it to the first pressure gauge 4. After receiving the first pressure detection command, the first pressure gauge 4 collects the pipeline pressure data of the branch pipe 8 according to the first pressure detection command. It is also understandable that the first pressure detection command includes a pressure detection start command and detection parameter information. The pressure detection start command is used to control the working state of the first pressure gauge 4, and the detection parameter information includes the number of detections, the first time, the detection start time, etc.

[0100] Specifically, in this embodiment, the detection count can be twice, with an interval of 30 minutes and a detection start time of 1 minute. After receiving the first execution result from the first valve 1, the first controller 7 generates a first pressure detection command containing parameters such as two detection counts, a first interval of 30 minutes, and a detection start time of 1 minute, and transmits it to the first pressure gauge 4. Upon receiving the first pressure detection command, the first pressure gauge 4 begins detection 1 minute after the first valve 1 closes, collecting the branch pipe 8 pressure data for the first minute to obtain first data. A second detection is performed 31 minutes after the first valve 1 closes, collecting the branch pipe 8 pressure data for the 31st minute to obtain second data. After obtaining the first and second data, the first pressure gauge 4 combines the first and second data into first pressure data and transmits it to the first controller 7. Subsequently, the first controller 7 uploads the first pressure data to the platform. Furthermore, the specific parameters of the first pressure detection command can be adjusted according to actual needs. This example is for illustrative purposes only and does not constitute any limitation on this application.

[0101] Step 120: The main controller executes the second task and the second pressure task sequentially according to the first execution result, and transmits the second execution result of the second task to the main controller, and uploads the second pressure data of the second pressure task to the platform. The second task is the task process of the main controller controlling the second valve 2 to close, and the second pressure task is the task process of the main controller controlling the second pressure gauge 5 to detect the pipeline pressure of the horizontal main pipe 9.

[0102] In some embodiments, in step 120, where the main controller sequentially executes the second task and the second pressure task based on the first execution result, the second task includes:

[0103] Step 121: The main controller generates a second valve-closing command based on the first execution result and transmits the second valve-closing command to the second valve 2;

[0104] Step 122: The second valve 2 executes the second valve closing command. After the second valve closing command is executed, the second execution result is generated and transmitted to the main controller.

[0105] The second stress task includes:

[0106] Step 123: The main controller generates a second pressure detection command based on the second execution result and transmits the second pressure detection command to the second pressure gauge 5;

[0107] Step 124: The second pressure gauge 5 acquires the third data and the fourth data according to the second time in the second pressure detection instruction, wherein the second time is used to characterize the time interval between acquiring the third data and the fourth data, the third data is the pressure data detected by the horizontal main pipe 9 in the first detection, and the fourth data is the pressure data detected by the horizontal main pipe 9 in the second detection;

[0108] Step 125: The second pressure gauge 5 combines the third data and the fourth data into the second pressure data and then transmits it to the main controller.

[0109] Understandably, in an urban complex, a horizontal main pipe 9 connects to multiple branch pipes 8, each corresponding to a different user. When all users on a certain horizontal main pipe 9 stop using gas, the main controller receives the first execution result of the branch pipes 8 corresponding to all users on that horizontal main pipe 9. Based on this, it confirms that all users on that horizontal main pipe 9 have stopped using gas, generates a second valve-closing command, and transmits it to the second valve 2. The second valve 2 executes the second valve-closing command. After the second valve-closing command is executed, the second valve 2 generates the second execution result and transmits the second execution result to the main controller.

[0110] It is understandable that after receiving the second execution result of the second valve 2, the main controller can generate a second pressure detection command based on the received second execution result and transmit it to the second pressure gauge 5. After receiving the second pressure detection command, the second pressure gauge 5 collects the pipeline pressure data of the branch pipe 8 according to the second pressure detection command. When the second pressure gauge 5 obtains the third and fourth data, it combines the third and fourth data into second pressure data and transmits it to the main controller. Subsequently, the main controller uploads the first pressure data to the platform. It is worth noting that the second execution result is similar to the aforementioned first execution result, the second valve closing command is similar to the aforementioned valve closing command, and the second pressure detection command is similar to the aforementioned first pressure detection command. These can be easily deduced by analogy, and this application will not elaborate on these related contents here.

[0111] Step 130: The main controller executes the third task and the third pressure task sequentially according to the second execution result, and transmits the third execution result of the third task to the main controller, and uploads the third pressure data of the third pressure task to the platform. The third task is the task process of the main controller controlling the third valve 3 to close, and the third pressure task is the task process of the main controller controlling the third pressure gauge 6 to detect the pipeline pressure of the riser 10.

[0112] It is understandable that the main controller generates a third valve-closing command based on the third execution result and transmits the third valve-closing command to the third valve 3. The third valve 3 executes the third valve-closing command. After the execution of the third valve-closing command is completed, the third valve 3 generates the third execution result and transmits the third execution result to the main controller.

[0113] It is understood that the third pressure task includes the main controller generating a third pressure detection command based on the third execution result, and transmitting the third pressure detection command to the third pressure gauge 6. The third pressure gauge 6 acquires the fifth and sixth data according to the third time in the third pressure detection command. The third pressure gauge 6 combines the third and fourth data into the third pressure data and transmits it to the main controller. Subsequently, the main controller uploads the first pressure data to the platform. It is also understood that the third time is used to characterize the time interval between the acquisition of the fifth and sixth data. The fifth data is the pressure data detected by the riser 10 in the first detection, and the sixth data is the pressure data detected by the riser 10 in the second detection. It is also understood that the third execution result is similar to the aforementioned first execution result, the third valve closing command is similar to the aforementioned valve closing command, and the third pressure detection command is similar to the aforementioned first pressure detection command. These related contents can be simply deduced, and this application will not elaborate further here.

[0114] Step 140: The platform determines whether there is a leak in the pipeline based on the first pressure data, the second pressure data, and the third pressure data.

[0115] In some embodiments, step 140, where the platform determines whether there is a leak in the pipeline based on the first pressure data, includes:

[0116] Step 141: The platform extracts the first data and the second data from the first pressure data;

[0117] Step 142: Compare the size of the first data and the second data;

[0118] Step 143: If the value of the second data is equal to the value of the first data, then it is determined that there is no gas leakage in the branch pipe 8.

[0119] Step 144: If the value of the second data is less than the value of the first data, it is determined that there is a gas leak in the branch pipe 8. The platform transmits a gas leak command to the first controller 7, wherein the gas leak command is used to control the state of the first valve 1 corresponding to the branch pipe 8 to be normally closed through the first controller 7.

[0120] It is understandable that the platform can determine whether a specific pipeline has a leak when it receives at least one of the first pressure data, second pressure data, and third pressure data. Specifically, in this embodiment, after receiving the first pressure data of a branch pipe 8 corresponding to a gas user, the platform can extract the first and second data from the first pressure data. By comparing whether the branch pipe 8 pressure data in the first data and the branch pipe 8 pressure data in the second data are equal, if the branch pipe 8 pressure data in the second data is equal to the branch pipe 8 pressure data in the first data, the platform determines that there is no gas leak in the branch pipe 8 and does not perform any action. If the branch pipe 8 pressure data in the second data is less than the branch pipe 8 pressure data in the first data, the platform determines that there is a gas leak in the branch pipe 8, generates a gas leak command, and transmits it to the first controller 7. After receiving the gas leak command, the first controller 7 closes the first valve 1 controlling the branch pipe 8, making the first valve 1 normally closed. Furthermore, when the platform determines that there is a gas leak in the branch pipe 8, the platform can issue a warning message to the relevant user and arrange for relevant personnel to carry out maintenance work on the branch pipe 8.

[0121] It is also understandable that, in addition to controlling the state of the first valve 1 corresponding to the branch pipe 8 to be normally closed, the gas leak command is also used to store the relevant information of the branch pipe 8 where the gas leak occurred and the relevant information of the horizontal main pipe 9 connected to the branch pipe 8 where the gas leak occurred in the first controller 7. When the user corresponding to the branch pipe 8 where the gas leak occurred has a gas demand, the first controller 7 rejects the user's gas demand based on the relevant information of the branch pipe 8, which can ensure that when the branch pipe 8 has a gas leak, the gas leaked from the branch pipe 8 is only a part of the low-pressure gas stored in the branch pipe 8, thereby controlling the amount of gas leak. In this way, the leaked gas, after mixing with air, is not enough to reach the lower limit concentration of gas explosion, reducing the occurrence of gas safety accidents.

[0122] It is understandable that the platform's determination of whether there is a leak in the horizontal main pipe 9 based on the second pressure data and the platform's determination of whether there is a leak in the riser pipe 10 based on the third pressure data are similar to the aforementioned determination of whether there is a leak in the pipeline based on the first pressure data. They can be easily deduced by analogy, and this application will not elaborate further here.

[0123] In some embodiments, the detection method further includes:

[0124] Step 150: The first controller 7 responds to the user's second instruction, generates a valve opening instruction, and executes the first process according to the valve opening instruction;

[0125] Step 150, the execution of the first process according to the valve opening command, includes:

[0126] Step 151: The first controller 7 transmits the valve opening command to the first valve 1, and the first valve 1 executes the valve opening command;

[0127] Step 152: After the valve opening command is executed, a first valve opening execution result is generated and transmitted to the first controller 7.

[0128] It is understood that, in this embodiment of the application, when a gas user in a city commercial complex has a gas demand, the gas user can send a second command to the first controller 7 through the gas appliance's open button. After receiving the second command, the first controller 7 generates a valve opening command and transmits the valve opening command to the first valve 1. The first valve 1 receives the valve opening command and executes it. When the state of the first valve 1 is open, the first valve 1 ends the valve opening process and generates a first valve opening execution result, which is then transmitted to the first controller 7. It is also understood that, when a gas user in a city commercial complex has a gas demand, and there is a gas leak in the branch pipe 8 corresponding to the gas user, or a gas leak in the horizontal main pipe 9 connected to the corresponding branch pipe 8, or a gas leak in the riser pipe 10, the first controller 7 will not respond to the user's second command, and the first valve 1 will remain in a normally closed state.

[0129] In some embodiments, the detection method further includes:

[0130] Step 160: The first controller 7 responds to the user's second instruction, generates a valve opening request instruction, and executes the second process according to the valve opening request instruction;

[0131] Step 160, the second process, includes:

[0132] Step 161: The first controller 7 transmits a valve opening request command to the main controller, wherein the valve opening request command is used to request the opening of the second valve 2 and / or the opening of the third valve 3;

[0133] Step 162: After the main controller executes the valve opening request command, the main controller transmits valve opening information to the first controller 7, wherein the valve opening information includes the opening status information of the second valve 2 and the opening status information of the third valve 3.

[0134] It is understandable that when the first valve 1 is in the open state, and the second valve 2 or the third valve 3 is in the normally closed state, the user cannot use gas normally. In this embodiment, the gas user can send a second command to the first controller 7 through the gas appliance's open button. After receiving the second command, the first controller 7 generates a valve opening request command and transmits it to the main controller. After receiving the valve opening request command, the main controller executes it. When both the second valve 2 and the third valve 3 are in the open state, the main controller ends execution and generates valve opening information, which is then transmitted to the first controller 7.

[0135] It is understandable that after executing the valve opening request command, the main controller generates a second valve opening command and a third valve opening command, and transmits the second valve opening command to the second valve 2. After executing the second valve opening command, the second valve 2 generates its opening status information and transmits it to the main controller; and transmits the third valve opening command to the third valve 3. After executing the third valve opening command, the third valve 3 generates its opening status information and transmits it to the main controller. The main controller combines the opening status information of the second valve 2 and the third valve 3 into valve opening information and transmits it to the first controller 7. It is also understandable that when the first controller 7 transmits the valve opening request command to the main controller, the valve states of the second valve 2 and the third valve 3 are not necessarily both in the normally closed state. When the first controller 7 transmits the valve opening request command to the main controller, and the second valve 2 is in the open state, the second valve 2 can still transmit its opening status information to the main controller according to the second valve opening command. The same applies to the third valve 3. This will not be elaborated further in this application.
