[0041] If the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is located outside the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal, then after marking the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter as a node water meter, the transportation pipeline reflected by the connection relationship between the node water meters that have a connection relationship with the explosion-proof water meter that sends the abnormal signal and the transportation pipeline reflected by the connection relationship between each of the node water meters that have a connection relationship are confirmed as outflow paths;

[0042] If the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is not located outside the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal, then the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is marked as the node water meter, and then the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is confirmed as the starting water meter and step d is repeated.

[0043] In a possible implementation of the first aspect, the shutdown instruction is sent to the explosion-proof water meter that sends the abnormal signal and an explosion-proof water meter corresponding to an upstream water meter in a corresponding connection relationship with the explosion-proof water meter that sends the abnormal signal;

[0071] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0072] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0073] In the related art, when explosion-proof water meters are used in chemical plant environments, the water transported by the explosion-proof water meters in the complex environment of the chemical plant can easily react with a variety of chemical substances (lithium, sodium, potassium, etc.) to cause explosions, combustion, or the generation of harmful gases and other dangerous situations, endangering personal safety.

[0074] To solve the above problems, the embodiment of the present application provides an explosion-proof water meter control method and device. In the method, by first obtaining water meter distribution information including the distribution position and connection relationship information of at least one explosion-proof water meter, the position distribution of the water meter in the chemical plant and the transportation direction of the liquid between each explosion-proof water meter are clarified, providing a basis for subsequent steps. Then, based on the water meter distribution information, a water meter control system including multiple explosion-proof water meters and the connection relationship between each explosion-proof water meter is obtained, and the data of each explosion-proof water meter is monitored in real time through the water meter control system, and the user is reminded to deal with the explosion-proof water meter that sends an abnormal signal in time. Then, based on the water meter control system, the explosion-proof water meter is controlled, and the number of explosion-proof water meters that need to be closed is determined by analyzing the flow path and flow area of ​​the liquid, which can improve the problem of accidental contact between the water in the water meter and the chemical substances (lithium, sodium, potassium, etc.) in the chemical plant, resulting in explosion, combustion or generation of harmful gases and other dangerous situations.

[0075] The explosion-proof water meter control method provided in the embodiment of the present application can be applied to an explosion-proof water meter control device. In this case, the explosion-proof water meter control device is the executor of the explosion-proof water meter control method provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the explosion-proof water meter control device.

[0076] For example, the explosion-proof water meter control device may include a control device and at least two explosion-proof water meters. The control device is in communication connection with each explosion-proof water meter. The explosion-proof water meter is a device capable of real-time monitoring of the state of the liquid in the pipeline. For example, the explosion-proof water meter may include a case, a shut-off valve, an electronic control device, a flow sensor, a temperature sensor, and a pressure sensor, etc., but is not limited thereto. For example, the control device may be a single-chip microcomputer, a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a desktop computer, a computing device or a computer connected to a wireless modem, a laptop computer, a handheld communication device, a handheld computing device, etc.

[0077] In order to better understand the explosion-proof water meter control method provided in the embodiment of the present application, the specific implementation process of the explosion-proof water meter control method provided in the embodiment of the present application is exemplarily introduced below.

[0078] Figure 1 A schematic flow chart of an explosion-proof water meter control method provided in an embodiment of the present application is shown, and the explosion-proof water meter control method includes:

[0079] S100, obtaining water meter distribution information; wherein the water meter distribution information includes the distribution position and connection relationship information of at least one explosion-proof water meter; the connection relationship information includes at least one connection relationship, the connection relationship reflecting that two explosion-proof water meters are connected through a transportation pipeline, one of the two explosion-proof water meters connected through the transportation pipeline is an upstream water meter, and the other explosion-proof water meter is a downstream water meter, and the extension direction extending from the upstream water meter along the transportation pipeline to the downstream water meter reflects the flow direction of the liquid between the explosion-proof water meter corresponding to the upstream water meter and the explosion-proof water meter corresponding to the downstream water meter.

[0080] It is understandable that the method of obtaining water meter distribution information may be to receive data input by a user, or to obtain engineering drawings and then analyze them according to water meter identification and pipeline identification marked on the drawings, but is not limited thereto. Obtaining water meter distribution information including the distribution location and connection relationship information of at least one explosion-proof water meter can clarify the location distribution of the water meters and the transportation direction of the liquid between the explosion-proof water meters, providing a basis for subsequent steps.

[0081] For example, assuming there are two explosion-proof water meters A and B, the liquid can flow directly from explosion-proof water meter A to explosion-proof water meter B without passing through other explosion-proof water meters. Then there is a connection relationship between the two explosion-proof water meters A and B, and water meter A is the upstream water meter and water meter B is the downstream water meter.

[0082] S200, obtaining a water meter control system based on water meter distribution information; wherein the water meter control system includes a plurality of explosion-proof water meters and connection relationships between the explosion-proof water meters.

[0083] It can be understood that the water meter control system can be obtained based on the water meter distribution information by receiving the danger level label and the area label added by the user to each water meter in the water meter distribution information, or by obtaining the working area distribution map, overlapping the working area distribution map with the explosion-proof water meter distribution map reflected by the water meter distribution information, and determining the location of each explosion-proof water meter in the water meter distribution information on the working area distribution map, etc., but not limited thereto. The water meter control system including multiple explosion-proof water meters and the connection relationship between each explosion-proof water meter obtained based on the water meter distribution information can more intuitively and conveniently manage all explosion-proof water meters in the chemical industry, monitor the data of each explosion-proof water meter in real time through the water meter control system, and remind the user to deal with the explosion-proof water meter that sends abnormal signals in time.

[0084] In one possible implementation, see Figure 2 , S200, obtaining a water meter control system based on water meter distribution information, including:

[0085] S210, obtaining application area information; wherein the application area information includes at least one working area in a building where the explosion-proof water meter is used.

[0086] It is understood that the method of obtaining the application area information may be receiving data transmitted by the user, or identifying various workplaces marked on the architectural drawings, etc., but is not limited thereto. Obtaining the application area information of at least one work area in a building where an explosion-proof water meter is used can clarify the working range of the explosion-proof water meter and provide a basis for subsequent steps.

[0087] S220, obtaining regional distribution information based on the application area information; wherein the regional distribution information includes high-risk areas and low-risk areas, the high-risk areas reflecting that the liquid transported by the explosion-proof water meter is likely to react with the materials or equipment stored in the working area when passing through the working area, causing explosion, combustion or generation of harmful gases; the low-risk areas are working areas within the building where the explosion-proof water meter is used, and the area range of the working area does not come into contact with the area range of the high-risk area.

[0088] It is understandable that the method of obtaining regional distribution information based on application area information may be to receive work attribute labels (high-risk area labels, low-risk area labels) added by users to each workplace in the application area information, or to obtain substances that need to be handled in each workplace in the application area information, and determine whether these substances will react with water to cause adverse effects, etc., but is not limited to this. Obtaining regional distribution information including high-risk areas and low-risk areas based on application area information can provide a basis for judging the severity of unexpected situations and avoiding false alarms.

[0089] In one possible implementation, see Figure 3 , S220, obtaining regional distribution information based on the application area information, including:

[0090] S221, obtaining work content information; wherein the work content information includes material information corresponding to each work area, and the material information includes the material name of at least one material stored in the work area or required to be processed in the work area.

[0091] It is understood that the way to obtain the work content information may be to receive data transmitted by the user, or to analyze the material inbound and outbound records of each work area, etc., but is not limited thereto. Obtaining the work content information including the material information corresponding to each work area can provide a basis for determining whether the work area is a high-risk area or a low-risk area.

[0092] S222, determining whether the material name reflected by the material information included in the work content information corresponding to each work area will react with the liquid flowing through the explosion-proof water meter to cause explosion, combustion or generation of harmful gas.

[0093] It can be understood that the method for judging whether the material reflected by the material name included in the material information of the work content information corresponding to each work area will react with the liquid flowing through the explosion-proof water meter to cause explosion, combustion or generation of harmful gas can be to query the material name included in the material information of the work content information corresponding to each work area on the chemical management website and analyze the query results, or to receive the hazard label or safety label added by the user to the material reflected by the material name included in the material information of the work content information corresponding to each work area, but it is not limited thereto. Judging whether the material reflected by the material name included in the material information of the work content information corresponding to each work area will react with the liquid flowing through the explosion-proof water meter to cause explosion, combustion or generation of harmful gas is to judge whether the work area is a high-risk area or a low-risk area.

[0094] For example, assuming that a work area needs to process metallic sodium or potassium-sodium alloy, this area is a high-risk area. assuming that a work area does not store or process any materials, this area is a low-risk area.

[0095] S223, if the material name included in the material information in the work content information corresponding to the work area reflects that the material will react with the liquid flowing through the explosion-proof water meter to cause explosion, combustion or generation of harmful gas, then the work area is confirmed as a high-risk area.

[0096] It can be understood that if the material information in the work content information corresponding to the working area includes a material name that reflects a material that will react with the liquid flowing through the explosion-proof water meter to cause an explosion, combustion, or generate harmful gases, it means that the material in the area will undergo a chemical reaction with water that is not conducive to safety, and the working area is confirmed as a high-risk area.

[0097] S224: If the material name included in the material information in the work content information corresponding to the work area reflects that the material will not react with the liquid flowing through the explosion-proof water meter to cause explosion, combustion or generation of harmful gas, then the work area is confirmed as a low-risk area.

[0098] It can be understood that if the material information in the work content information corresponding to the working area includes a material name reflecting a material that will not react with the liquid flowing through the explosion-proof water meter to cause explosion, combustion or generation of harmful gases, it means that the material in the area will not undergo a chemical reaction with water that is not conducive to safety, and the working area is confirmed as a low-risk area.

[0099] S225: Confirm the high-risk area and the low-risk area as the area distribution information.

[0100] It can be understood that identifying the high-risk area and the low-risk area as the regional distribution information can provide a basis for subsequent steps.

[0101] S230, obtaining a water meter control system based on the water meter distribution information and the regional distribution information.

[0102] It can be understood that the water meter control system can be obtained based on the water meter distribution information and the regional distribution information by receiving data transmitted by the user after analyzing the water meter distribution information and the regional distribution information, or by classifying the explosion-proof water meters according to the positions of the explosion-proof water meters in the water meter distribution information in each area in the regional distribution information, and then obtaining the water meter control system according to the connection relationship between the explosion-proof water meters, etc., but is not limited thereto. Obtaining the water meter control system based on the water meter distribution information and the regional distribution information can ensure the reliability of the water meter control system.

[0103] In one possible implementation, see Figure 4 , S230, obtaining a water meter control system based on the water meter distribution information and the regional distribution information, including:

[0104] S231, based on the distribution position and connection relationship information in the water meter distribution information, determine whether the transportation pipelines corresponding to at least two explosion-proof water meters in a connection relationship are completely or partially located in the high-risk area.

[0105] It can be understood that based on the distribution position and connection relationship information in the water meter distribution information, the method for judging whether the transportation pipelines corresponding to at least two explosion-proof water meters with a connection relationship are completely or partially located in the high-risk area can be to judge whether the geographical location reflected by the distribution position corresponding to one of the two explosion-proof water meters with a connection relationship is within the geographical location range reflected by the high-risk area, or to judge whether the projection of the transportation pipeline reflected by the connection relationship corresponding to each explosion-proof water meter along the gravity direction is in contact with the projection of the high-risk area along the gravity direction, etc., but not limited thereto. Judging whether the transportation pipelines corresponding to at least two explosion-proof water meters with a connection relationship are completely or partially located in the high-risk area is to judge the danger level of the explosion-proof water meter.

[0106] S232: If the transport pipelines corresponding to at least two connected explosion-proof water meters are completely or partially located in the high-risk area, the explosion-proof water meter corresponding to the transport pipeline completely or partially located in the high-risk area is confirmed as a first-class water meter.

[0107] It can be understood that if the transport pipelines corresponding to at least two explosion-proof water meters in a connection relationship are completely or partially located in the high-risk area, it means that the water in the transport pipeline connecting the at least two explosion-proof water meters is likely to leak and react with chemical substances. Confirming the explosion-proof water meter corresponding to the transport pipeline completely or partially located in the high-risk area as a first-class water meter can provide a basis for subsequent steps.

[0108] S233, if any part of the transport pipelines corresponding to at least two explosion-proof water meters in a connection relationship is not located in the high-risk area, the explosion-proof water meters corresponding to the transport pipelines whose parts are not located in the high-risk area are confirmed as second-category water meters.

[0109] It can be understood that if any part of the transport pipeline corresponding to at least two explosion-proof water meters in a connection relationship is not located in a high-risk area, it means that the possibility of water in the transport pipeline connecting the at least two explosion-proof water meters leaking and reacting with chemical substances is low. Confirming the explosion-proof water meter corresponding to the transport pipeline whose part is not located in a high-risk area as a second-class water meter can provide a basis for subsequent steps.

[0110] S234, confirming the connection relationship among the first type of water meter, the second type of water meter, the high-risk area, the low-risk area, and the connection relationship information as a water meter control system.

[0111] It can be understood that confirming the connection relationship among the first type of water meters, the second type of water meters, the high-risk areas, the low-risk areas, and the connection relationship information as the water meter control system can ensure the coverage of the water meter control system and improve the reliability of the water meter control system.

[0112] S300, controls explosion-proof water meters based on water meter control systems.

[0113] It can be understood that the method of controlling explosion-proof water meters based on the water meter control system can be to send the water meter type and the area type of the explosion-proof water meter that sends the abnormal signal to the user, and then receive the closing command or opening command sent by the user to control each explosion-proof water meter in the water meter control system, or it can be to determine the water meter type of the explosion-proof water meter that sends the abnormal signal and then control each explosion-proof water meter in the water meter control system through the high-risk area water meter control scheme or the low-risk area water meter control scheme. Controlling explosion-proof water meters based on the water meter control system can control each explosion-proof water meter more quickly and accurately, avoiding the problem of accidental contact between water and chemical substances (lithium, sodium, potassium, etc.) in the chemical plant due to rupture of the transportation pipeline or leakage of the explosion-proof water meter, resulting in explosion, combustion or generation of harmful gases and other dangerous situations.

[0114] In one possible implementation, see Figure 5 , S300, based on the water meter control system to control the explosion-proof water meter, including:

[0115] S310, obtaining an abnormal signal; wherein the abnormal signal is a signal sent by an explosion-proof water meter corresponding to the first type of water meter in the water meter control system or an explosion-proof water meter corresponding to the second type of water meter after detecting data abnormality, and the data abnormality includes at least one of a pressure value in the transport pipeline greater than a preset pressure value, a temperature value greater than a preset temperature value, and a flow rate exceeding a preset flow rate range.

[0116] It can be understood that the preset pressure value can be 0.1MPa, or 0.5MPa, etc., but not limited to this. The preset temperature value can be 80 degrees, or 85 degrees, etc., but not limited to this. The preset flow range can be 1.5 cubic meters / hour, or 3 cubic meters / hour, etc., but not limited to this. The way to obtain the pressure value in the transport pipeline can be to receive data transmitted by the user, or to obtain data monitored by the pressure sensor, etc., but not limited to this. The way to obtain the temperature value in the transport pipeline can be to receive data transmitted by the user, or to obtain data monitored by the temperature sensor, etc., but not limited to this. The way to obtain the flow in the transport pipeline can be to receive data transmitted by the user, or to obtain data monitored by the flow sensor, etc., but not limited to this. Obtaining an abnormal signal means that an explosion-proof water meter has detected abnormal data, and the transported water is at risk of leaking from the explosion-proof water meter that sent the abnormal signal, which requires further analysis and processing.

[0117] S320, determining whether the explosion-proof water meter that sends out an abnormal signal is a first-class water meter.

[0118] It can be understood that judging whether the explosion-proof water meter that sends out an abnormal signal is a first-class water meter is to judge whether the water flowing out of the explosion-proof water meter that sends out an abnormal signal may accidentally come into contact with dangerous chemicals (lithium, sodium, potassium, etc.), resulting in explosion, combustion or generation of harmful gases and other dangerous situations.

[0119] S330: If the explosion-proof water meter that sends out the abnormal signal is a first-class water meter, the explosion-proof water meter is controlled based on the high-risk area water meter control solution.

[0120] It can be understood that the method of controlling explosion-proof water meters based on the high-risk area water meter control scheme can be to send a shutdown command to all explosion-proof water meters in the high-risk area where the explosion-proof water meter that sends an abnormal signal is located, or to send a shutdown command only to the explosion-proof water meter that sends an abnormal signal and the explosion-proof water meter that is connected to the explosion-proof water meter that sends the abnormal signal, etc., but is not limited to this. Controlling explosion-proof water meters based on the high-risk area water meter control scheme can, to a certain extent, prevent the problem of accidental contact between water and chemical substances (lithium, sodium, potassium, etc.) in chemical plants, resulting in explosions, combustion, or the generation of harmful gases and other dangerous situations.

[0121] In one possible implementation, see Figure 6 In step S330, the explosion-proof water meter is controlled based on the high-risk area water meter control scheme, including:

[0122] S331, sending a closing instruction to the explosion-proof water meter that sends out an abnormal signal; wherein the closing instruction is used to instruct the explosion-proof water meter to close a valve to prevent water from flowing through.

[0123] It can be understood that sending a closing instruction to the explosion-proof water meter that sends out an abnormal signal to instruct the explosion-proof water meter to close the valve to prevent water from flowing through can prevent the explosion-proof water meter that sends out an abnormal signal from being damaged, causing water to overflow from the damaged water meter and come into contact with dangerous chemicals (lithium, sodium, potassium, etc.) and produce chemical reactions that are not conducive to safety.

[0124] S332, sending a closing instruction to the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal.

[0125] It can be understood that when a water pipe is damaged in the middle part, the detection data obtained by the water meter at the downstream position among the water meters located at both ends of the water pipe will have the largest fluctuation amplitude. Sending a shutdown command to the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal can prevent water from continuously flowing out from the damaged part of the conveying pipeline between the explosion-proof water meter that sends the abnormal signal and the upstream water meter corresponding to the explosion-proof water meter that sends the abnormal signal, and coming into contact with dangerous chemicals and causing chemical reactions that are not conducive to safety.

[0126] S333, confirm the source water meter; wherein the source water meter is an explosion-proof water meter in the high-risk area where the water can directly flow into the explosion-proof water meter that sends out an abnormal signal after passing through a certain explosion-proof water meter.

[0127] It can be understood that the way to confirm the source water meter can be to confirm as the source water meter the explosion-proof water meter that is located in the high-risk area where the explosion-proof water meter that sends the abnormal signal is located, and there is a connection relationship and the connection relationship corresponds to the explosion-proof water meter, there is at least one explosion-proof water meter located in the high-risk area, and there is at least another explosion-proof water meter located in the low-risk area. The explosion-proof water meter corresponding to the connection relationship is located in the low-risk area. It can also be based on the explosion-proof water meter that sends the abnormal signal as the starting point, and determine whether the upstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal is located in the low-risk area. If the upstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal is located in the low-risk area, then the explosion-proof water meter corresponding to the upstream water meter in the low-risk area is confirmed as the source water meter, etc., but it is not limited to this. Confirming the source water meter can provide a basis for subsequent steps.

[0128] In one possible implementation, see Figure 7 , S333, confirm the source water meter, including:

[0129] S3331, step a, confirming the explosion-proof water meter that sends out an abnormal signal as the retrieval water meter.

[0130] It can be understood that confirming the explosion-proof water meter that sends out an abnormal signal as the retrieval water meter can provide a basis for subsequent steps.

[0131] S3332, step b, determining whether the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is located in the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal.

[0132] It can be understood that the method of judging whether the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is located in the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal can be to judge whether the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is a second-class water meter, or to judge whether the position of the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is within the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal, etc., but not limited thereto. Judging whether the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is located in the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal can provide a basis for subsequent steps.

[0133] S3333, if the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is located in the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal, then the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is confirmed as the searched water meter and step b is repeated.

[0134] It can be understood that after confirming the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter as the searched water meter, repeating step b can ensure that the water flow can flow from the searched explosion-proof water meter to the explosion-proof water meter that sends the abnormal signal.

[0135] For example, assume that there are two water meters A and B that are connected, where water meter A is the upstream water meter, water meter B is the downstream water meter, water meter B is the retrieval water meter, water meter A and water meter B are connected, and both water meters A and B are located in the high-risk area where water meter B is located. After step b, water meter A will be confirmed as the retrieval water meter.

[0136] S3334, if the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the retrieved water meter is not located in the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal, then the explosion-proof water meter that is not located in the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal is confirmed as the source water meter.

[0137] It can be understood that the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter is not located in the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal, which means that the water flows from the low-risk area to the low-risk area where the explosion-proof water meter corresponding to the searched water meter is located through the explosion-proof water meter corresponding to the upstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the searched water meter. Confirming the explosion-proof water meter that is not located in the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal as the source water meter can provide a basis for subsequent steps.

[0138] For example, for example, suppose there are two water meters A and B that are connected, where water meter A is the upstream water meter, water meter B is the downstream water meter, water meter B is the retrieval water meter, water meter A and water meter B are connected, water meter B is located in a high-risk area, and water meter A is located in a low-risk area, then after step b, water meter A will be confirmed as the source water meter.

[0139] S334, sending a shutdown command to the source water meter.

[0140] It can be understood that sending a shutdown command to the source water meter can prevent water from continuing to flow into the high-risk area, and prevent water from flowing out from the damaged area and coming into contact with dangerous chemicals and causing chemical reactions that are not conducive to safety when other explosion-proof water meters or pipelines in the high-risk area are damaged due to high temperature or explosion.

[0141] S335, confirm the outflow path; wherein the outflow path is the flow path starting from the explosion-proof water meter that sends out the abnormal signal, and the water flows out along the transportation pipeline to the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal.

[0142] It can be understood that the outflow path can be confirmed by determining whether the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal is a second-class water meter. If it is a second-class water meter, the transportation pipeline reflected by the connection relationship corresponding to the determined explosion-proof water meter is confirmed as the outflow path, or the connection pipeline selected by the user is received and confirmed as the outflow path, etc., but not limited thereto. Confirming the outflow path can provide a basis for subsequent steps.

[0143] In one possible implementation, see Figure 8 , S335, confirming the outflow path, including:

[0144] S3351, step c, confirm the explosion-proof water meter that sends out an abnormal signal as the starting water meter.

[0145] It can be understood that confirming the explosion-proof water meter that sends out an abnormal signal as the starting water meter can provide a basis for subsequent steps.

[0146] S3352, step d, determining whether the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is located outside the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal.

[0147] It can be understood that the method for judging whether the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is located outside the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal can be to judge whether the explosion-proof water meter corresponding to the downstream water meter is a second-class water meter, or to judge whether the location of the explosion-proof water meter corresponding to the downstream water meter is within the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal, etc., but not limited thereto. Judging whether the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is located outside the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal can provide a basis for subsequent steps.

[0148] S3353, if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is located outside the high-risk area corresponding to the explosion-proof water meter that sends out an abnormal signal, then the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is marked as a node water meter, and the transportation pipeline reflected by the connection relationship between the node water meters that have a connection relationship with the explosion-proof water meter that sends out the abnormal signal and the transportation pipeline reflected by the connection relationship between each node water meter that has a connection relationship are confirmed as the outflow path.

[0149] It can be understood that if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is located outside the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal, it means that the water flows out of the high-risk area from the explosion-proof water meter corresponding to the starting water meter through the transportation pipeline from the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter. After marking the explosion-proof water meter located outside the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal as a node water meter, the transportation pipeline reflected by the connection relationship between the node water meters that have a connection relationship with the explosion-proof water meter that sends out the abnormal signal and the transportation pipeline reflected by the connection relationship between each node water meter that has a connection relationship are confirmed as the outflow path, which can provide a basis for subsequent steps.

[0150] Exemplarily, assume that there are three water meters A, B, and C that are connected, among which water meter A is the water meter that sends out an abnormal signal, water meter B is marked as a node water meter and is the starting water meter, water meter A is connected to water meter B, water meter B is connected to water meter C, water meters A and B are located in a high-risk area, and water meter C is located in a low-risk area. Then, after step b, water meter C will also be marked as a node water meter, and the transportation pipeline reflected by the connection relationship between water meter A and water meter B and the transportation pipeline reflected by the connection relationship between water meter B and water meter C will be confirmed as outflow paths.

[0151] S3354, if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is not located outside the high-risk area corresponding to the explosion-proof water meter that sends out the abnormal signal, then the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is marked as a node water meter, and then the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is confirmed as the starting water meter and step d is repeated.

[0152] It can be understood that if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter is not located outside the high-risk area corresponding to the explosion-proof water meter that sends the abnormal signal, it means that water cannot flow out of the high-risk area where the explosion-proof water meter corresponding to the starting water meter is located through the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter. After marking the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter as a node water meter, confirming the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter corresponding to the starting water meter as the starting water meter, and repeating step d can ensure that water can flow out of the high-risk area through the explosion-proof water meter corresponding to the node water meter.

[0153] For example, assume that there are two water meters A and B that are connected, where water meter A is the water meter that sends out an abnormal signal, water meter A and water meter B are connected, water meter A is located in a high-risk area, and water meter B is also located in a high-risk area. After step b, water meter B will be marked as a node water meter and confirmed as the starting water meter at the same time, and step b will be repeated.

[0154] S336, determining whether there are other explosion-proof water meters that send out abnormal signals on the outflow path in addition to the explosion-proof water meter corresponding to the starting water meter.

[0155] It is understandable that the way to determine whether there are other explosion-proof water meters that send abnormal signals on the outflow path in addition to the explosion-proof water meter corresponding to the starting water meter can be to determine whether other explosion-proof water meters on the outflow path send abnormal signals, or to determine whether the explosion-proof water meter that sends abnormal signals is located on the outflow path, etc., but is not limited thereto. Determining whether there are other explosion-proof water meters that send abnormal signals on the outflow path in addition to the explosion-proof water meter corresponding to the starting water meter can ensure the safety of the outflow path and provide a basis for subsequent steps.

[0156] S337, if there are other explosion-proof water meters that send out abnormal signals in addition to the explosion-proof water meter corresponding to the starting point on the outflow path, a closing instruction is sent to the explosion-proof water meter between the explosion-proof water meter corresponding to the starting point and the explosion-proof water meter that sends out abnormal signals on the outflow path.

[0157] It can be understood that if there are other explosion-proof water meters that send out abnormal signals in addition to the explosion-proof water meter corresponding to the starting point on the outflow path, it means that there may be other damage on the outflow path. Sending a shutdown command to the explosion-proof water meter between the explosion-proof water meter corresponding to the starting point and the explosion-proof water meter that sends out abnormal signals on the outflow path can, to a certain extent, prevent water from flowing out from the damaged part of the transportation pipeline between the explosion-proof water meter corresponding to the starting point on the outflow path and the explosion-proof water meter that sends out abnormal signals on the outflow path, and contacting with dangerous chemicals in the high-risk area to cause safety accidents.

[0158] For example, assuming that there are four water meters A, B, C, and D on the outflow path, water meter A is the starting point of the outflow path, and water meter D is the end point of the outflow path. If both water meters A and C send abnormal signals, a shutdown command will be sent to water meters A, B, and C.

[0159] S338, if there is no other explosion-proof water meter sending out abnormal signals on the outflow path except the explosion-proof water meter corresponding to the starting point, no closing instruction is sent to other explosion-proof water meters on the outflow path except the explosion-proof water meter corresponding to the starting point.

[0160] It can be understood that if there are no other explosion-proof water meters that send abnormal signals on the outflow path except the explosion-proof water meter corresponding to the starting point, it means that there is no damage in the transportation pipeline corresponding to the outflow path. Not sending a shutdown command to other explosion-proof water meters on the outflow path except the explosion-proof water meter corresponding to the starting point can enable the user to promptly pump out the remaining water in the transportation pipeline between the explosion-proof water meter corresponding to the starting point and the explosion-proof water meter corresponding to the end point from the end point of the transportation pipeline corresponding to the outflow path through water-using equipment or pumping equipment, and to a certain extent avoid the corresponding transportation pipeline on the outflow path from being damaged due to high temperature or explosion, resulting in water overflowing from the pipeline and expanding safety accidents.

[0161] For example, assuming that there are four water meters A, B, C, and D on the outflow path, water meter A is the starting point of the outflow path, and water meter D is the end point of the outflow path. If only water meter A sends an abnormal signal, then only a shutdown command will be sent to water meter A, and no shutdown command will be sent to water meters B, C, and D.

[0162] S340: If the explosion-proof water meter that sends out the abnormal signal is not a first-class water meter, the explosion-proof water meter is controlled based on the low-risk area water meter control solution.

[0163] It can be understood that the method of controlling the explosion-proof water meter based on the low-risk area water meter control scheme can be to send a shutdown command to all explosion-proof water meters in the low-risk area where the first type of water meter that sends the abnormal signal is located, or to send a shutdown command only to the explosion-proof water meter that is connected to the first type of water meter that sends the abnormal signal, etc., but is not limited thereto. Controlling the explosion-proof water meter based on the low-risk area water meter control scheme can enable users to handle safety accidents in low-risk areas more quickly to a certain extent.

[0164] In one possible implementation, see Fig. 9 In step S340, the explosion-proof water meter is controlled based on the low-risk area water meter control solution, including:

[0165] S341, sending a closing instruction to the explosion-proof water meter that sends the abnormal signal and the explosion-proof water meter corresponding to the upstream water meter in the corresponding connection relationship with the explosion-proof water meter that sends the abnormal signal.

[0166] It can be understood that sending a shutdown command to the explosion-proof water meter that sends an abnormal signal and the upstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal can prevent water from overflowing from the explosion-proof water meter that sends the abnormal signal or from the damaged part of the transportation pipeline corresponding to the connection relationship corresponding to the explosion-proof water meter.

[0167] S342, determining whether the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal is located in a high-risk area.

[0168] It can be understood that the method for judging whether the explosion-proof water meter corresponding to the downstream water meter in the corresponding connection relationship with the explosion-proof water meter that sends the abnormal signal is located in the high-risk area can be to judge whether the explosion-proof water meter corresponding to the downstream water meter in the corresponding connection relationship with the explosion-proof water meter that sends the abnormal signal is a first-class water meter, or it can be to judge whether the position of the explosion-proof water meter corresponding to the downstream water meter in the corresponding connection relationship with the explosion-proof water meter that sends the abnormal signal is within the range of the high-risk area, etc., but not limited thereto. Judging whether the explosion-proof water meter corresponding to the downstream water meter in the corresponding connection relationship with the explosion-proof water meter that sends the abnormal signal is located in the high-risk area can provide a basis for subsequent steps.

[0169] S343, if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal is located in the high-risk area, a closing instruction is sent to the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal.

[0170] It can be understood that if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends out the abnormal signal is located in a high-risk area, then sending a shutdown command to the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends out the abnormal signal can to a certain extent avoid the safety accidents in the low-risk area from affecting the safety management in the high-risk area.

[0171] S344, if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal is not located in the high-risk area, a closing instruction is not sent to the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends the abnormal signal.

[0172] It can be understood that if the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends out the abnormal signal is not located in the high-risk area, then not sending a shutdown command to the explosion-proof water meter corresponding to the downstream water meter in the connection relationship corresponding to the explosion-proof water meter that sends out the abnormal signal can enable the user to promptly pump out the remaining water in the transportation pipeline through water-using equipment or pumping equipment, thereby reducing the influencing factors of the accident.

[0173] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0174] Corresponding to the explosion-proof water meter control method described in the above embodiment, the embodiment of the present application also provides an explosion-proof water meter control system, and each unit of the system can implement each step of the explosion-proof water meter control method. Fig.10 A structural block diagram of an explosion-proof water meter control system provided in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.
