Abstract
Description
Technical Field
[0001] The present invention relates to the field of gas technology, and in particular to a detection method, system, device and storage medium for an electric valve in a gas pipeline network. Background Art
[0002] The gas industry requires the installation of electric valves in pipeline networks so that emergency personnel can remotely and promptly control the opening and closing status of pipelines in the event of an accident, quickly controlling leaks. However, electric valves, especially buried valves, are susceptible to static friction when left unopened for extended periods, causing them to become stuck and difficult to close or activate. Furthermore, back-office personnel cannot verify the effectiveness of the valve's actuator module, potentially hindering its effectiveness in emergency situations. Furthermore, when electric valves are powered by batteries, common battery status monitoring methods include voltage and charge levels. For buried electric valves that remain underground for extended periods, accurate battery status cannot be determined, making it difficult to effectively monitor the valve using charge levels. Furthermore, voltage monitoring can vary significantly between high-power and low-power conditions, making it difficult to effectively monitor the battery status of buried electric valves based on voltage.

[0052] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0053] Reference Figure 1 The present invention provides a method for detecting an electric valve in a gas pipeline network, which includes but is not limited to the following steps:
[0054] Step 110: Acquire first pressure and flow data of a current node in the gas network, where the first pressure and flow data includes second pressure and flow data of a preset time period, historical industrial and commercial simulated gas consumption, and real-time detection pressure and flow data;
[0055] Step 120: When the first pressure flow data meets a first preset requirement, controlling the execution module of the electric valve to execute a first preset working state;
[0056] Step 130: Obtain torque change data, battery voltage change data, and electric valve stem rotation data of the execution module in the first preset working state;
[0057] Step 140 : When the battery voltage change data is abnormal or when the torque change data meets the second preset requirement and the rotation data of the electric valve stem meets the third preset requirement, generate an alarm signal.
[0058] Reference Figure 2In this embodiment of the present application, for the electric valve to obtain the first pressure and flow data for the current node in the gas pipeline network, the control module 260 needs to periodically query the system backend via the wireless communication module 250, querying the current pressure and flow data of the corresponding pipeline node as the first pressure and flow data. After receiving the query information, the system backend compares the current pressure and flow data with the first preset requirement and automatically determines whether the current pressure and flow data meets the preset test conditions. If the current pressure and flow data meets the first preset requirement, the system backend sends a confirmation to the operation staff on duty. After the operation staff confirms, the system backend sends a test permission response to the electric valve, thereby obtaining the current pressure and flow data of the corresponding pipeline node as the first pressure and flow data. For example, the first preset requirement means that the pipeline pressure at the current time should be greater than the average pressure of the pipeline network for the day, and the pipeline flow should be less than the average flow of the pipeline network for the day. It can be understood that when the current pressure and flow data meet the first preset requirement, testing the gas pipeline electric valve can effectively reduce the impact on pipeline network operations.
[0059] In this embodiment of the present application, the first pressure-flow data includes second pressure-flow data for a preset time period, historical simulated industrial and commercial gas usage, and real-time detected pressure-flow data. In this embodiment, the preset time period may include, but is not limited to, 12:00 AM to 1:00 AM, 12:00 AM to 2:00 AM, 12:00 AM to 3:00 AM, or 1:00 AM to 2:00 AM. The pressure-flow data of the gas pipeline network during this preset time period is used as the third pressure-flow data. Taking 12:00 AM to 3:00 AM as an example, since gas usage for both residential and commercial users tends to be minimal during this time period, the pressure-flow data of the gas pipeline network during this time period can be obtained as the third pressure-flow data, and the pressure-flow data within this third pressure-flow data that is less than a flow threshold and greater than a pressure threshold can be used as the second flow data. Obtaining the historical simulated industrial and commercial gas usage of the current node in the gas pipeline network includes obtaining the historical industrial and commercial gas usage and the pipeline network information to which the current node belongs. Specifically, the historical industrial and commercial gas usage data and the pipeline network information corresponding to the current pipeline network can be queried online from a server, and then a simulation can be performed based on the queried historical industrial and commercial gas usage and pipeline network information to obtain the historical simulated industrial and commercial gas usage. The real-time detection pressure flow data of the current node of the gas pipeline network can be obtained by obtaining the real-time pressure monitoring information of the current node through the pressure monitoring point installed at the node accessory, and then performing data analysis based on the real-time pressure monitoring information to obtain the real-time detection pressure flow data of the current node.
[0060] Reference Figure 2 In the embodiment of the present application, when the first pressure flow data meets the first preset requirement, the execution module 210 of the electric valve is controlled to execute the first preset working state. Figure 2 Taking the illustrated system as an example, the first preset operating state refers to the electric valve actuator module 210 driving the valve stem to rotate to achieve the valve opening or closing function. This is equivalent to actively testing the valve. During the test, the valve stem only needs to be rotated to obtain the test results, without fully opening or closing the valve. During the process of the electric valve actuator module 210 executing the first preset operating state, torque change data, battery voltage change data, and electric valve stem rotation data are recorded. Acquiring the battery voltage change data of the actuator module 210 in the first preset operating state includes acquiring the initial battery voltage data and current power consumption data of the actuator module 210 in the first preset operating state, and then determining the battery voltage change data based on the initial battery voltage data and the current power consumption data. For example, the battery power corresponding to the battery before the start of the test during the current test process is used as the initial battery voltage data, and the battery power corresponding to the battery at the end of the test is used as the current power consumption data. That is, the battery voltage change data can be obtained by subtracting the current power consumption data from the initial battery voltage data.
[0061] In an embodiment of the present application, an alarm signal is generated when the battery voltage change data is abnormal or when the torque change data meets a second preset requirement and the electric valve stem rotation data meets a third preset requirement. Specifically, when the torque change data exceeds a first torque threshold and the electric valve stem rotation data is less than a revolution threshold, a stop test signal and a warning signal are generated. This indicates that the valve may be stuck and the electric valve alone cannot open the valve. Forcing the valve open may damage the electric valve or the valve itself, requiring subsequent on-site inspection of both the electric valve and the valve. When the torque change data is less than a second torque threshold, a stop test signal and a warning signal are generated. This indicates that there is a disconnect between the valve and the electric valve, preventing the electric valve from opening or closing the valve. When the fluctuation amplitude of the torque change data exceeds the amplitude threshold, a warning signal is generated. This indicates that there is a potential risk to the valve, including the presence of foreign matter inside the valve that may affect the valve opening and closing. Specifically, the first torque threshold can be the minimum torque required to drive the valve stem to rotate one revolution, and the revolution threshold is 1. The second torque threshold can be the minimum torque required to drive the valve stem to rotate.
[0062] In summary, the embodiment of the present application reduces the impact on pipeline network operations by performing active testing when the pipeline network gas consumption is low, and can obtain the true status of the valve so as to implement corresponding measures and avoid the situation where the electric valve cannot be remotely operated in the event of a real accident.
