[0002] In power systems and other electrical control systems, pressure sensors are commonly used as interlocking or actuating elements for pressure protection in various scenarios requiring pressure measurement. Therefore, regularly checking the health status of pressure sensors is essential to ensure the reliable operation of pressure detection systems and other pressure control systems.

[0003] In existing technologies, the health status of pressure sensors is typically detected using a pressure calibrator. Specifically, operators connect the pressure sensor to the pressure calibrator, then observe and record the pressure values ​​displayed by the calibrator in real time. These pressure values ​​are then analyzed to complete the health status detection of the pressure sensor.

[0004] However, relying entirely on manual inspection of pressure sensors in the routine maintenance of pressure testing systems containing a large number of sensors requires a significant amount of repetitive work, leading to high labor intensity and testing costs. Secondly, manual observation and operation of the pressure calibrator results in inaccurate pressure sensor measurement data and unreliable health status assessment results. Summary of the Invention

[0034] Example 1

[0035] Figure 1 This is a flowchart of a method for detecting the health status of a pressure sensor according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the health status of a pressure sensor needs to be detected. This method can be executed by a pressure sensor health status detection device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0036] Step 110: Obtain the first pressure dataset applied to the pressure sensor by the pressure applying device corresponding to the pressure sensor under standard conditions, and the first operating state of the pressure sensor corresponding to each data in the first pressure dataset.

[0037] In this embodiment, the first pressure dataset can be a collection of pressure data applied to the pressure sensor by the pressure-applying device under the standard state of the pressure sensor. The standard state can be the state maintained by the pressure sensor when it leaves the factory. Specifically, the state of the pressure sensor before its first application can be taken as the standard state. Before the first application, the operating state of the pressure sensor is measured by the pressure-applying device to obtain the first pressure dataset. The first operating state can be used to reflect the operating state of the pressure sensor under the standard state. In practical applications, the pressure-applying device can apply pressure to the pressure sensor. When the applied pressure reaches the operating threshold of the pressure sensor, the pressure sensor will trigger the normally open switch to close or the normally closed switch to open, i.e., an operation occurs. When the applied pressure does not reach the operating threshold of the pressure sensor, the pressure sensor will maintain the normally open switch open or the normally closed switch closed, i.e., no operation occurs.

[0038] In this embodiment, the first operating state can be either a non-operating state or an operating state, where pressure is applied to the pressure sensor by a pressure-applying device under standard conditions.

[0039] In this step, specifically, under the standard factory condition of the pressure sensor, pressure can be applied to the pressure sensor using a pressure-applying device to obtain the operating status of the pressure sensor.

[0040] Step 120: Under the application state of the pressure sensor, obtain the second pressure dataset applied by the pressure applying device to the pressure sensor, and the second operating state of the pressure sensor corresponding to each data in the second pressure dataset.

[0041] In this embodiment, the second pressure dataset can be a collection of pressure data applied to the pressure sensor by the pressure-applying device under the application state of the pressure sensor. The application state refers to the state of the pressure sensor during actual use. Specifically, during the actual use of the pressure sensor, the second pressure dataset is obtained by measuring the operating state of the pressure sensor through the pressure-applying device. As the pressure sensor is installed and used, its response to external pressure may become less sensitive; therefore, it is necessary to monitor the pressure sensor under the application state. The second operating state can be used to reflect the operating state of the pressure sensor under the application state. Specifically, the second operating state can be the state in which the pressure sensor operates or does not operate under the application state.

[0042] In this step, specifically, after the pressure sensor is installed and applied, pressure can be applied to the pressure sensor through a pressure-applying device to obtain the operating state of the pressure sensor.

[0043] For example, when the pressure sensor reaches the action threshold, the second action state can be set to 1; when the pressure sensor does not act, the second action state can be set to 0.

[0044] Step 130: Determine the health status of the pressure sensor based on the first pressure dataset, each first action state, the second pressure dataset, and each second action state.

[0045] In this embodiment, the health status of the pressure sensor reflects its operational reliability over time, facilitating timely adjustment of its characteristic parameters. Since the pressure sensor is a crucial component for pressure measurement, a healthy pressure sensor enables accurate and reliable detection of electrical equipment, thereby improving the operational reliability of the electrical equipment.

[0046] In this step, specifically, under standard conditions, when the pressure sensor is activated, the first target pressure data applied by the current pressure-applying device to the pressure sensor is recorded; under application conditions, when the pressure sensor is activated, the second target pressure data applied by the current pressure-applying device to the pressure sensor is recorded.

[0047] For example, the health status of the pressure sensor can be obtained by comparing the first target pressure data and the second target pressure data. For instance, if the first target pressure data and the second target pressure data are the same, the pressure sensor can be considered healthy; or, if the first target pressure data and the second target pressure data are different, but the difference between them does not exceed a user-preset threshold, the pressure sensor can be considered healthy; or, if the first target pressure data and the second target pressure data are different, and the difference between them exceeds a user-preset threshold, a warning about the pressure sensor's status or a pressure sensor malfunction can be reported to the user.

[0048] Another example is that the pressure sensor's variation under standard and application conditions can be determined by performing arithmetic or logical operations on the first action time corresponding to the first target pressure data, the second action time corresponding to the second target pressure, the first target pressure data, and the second target pressure. If this variation exceeds a preset difference threshold, a pressure sensor status warning or a pressure sensor status malfunction is determined; otherwise, the pressure sensor is determined to be healthy. There are many ways to determine this variation. For example, the variation coefficient of the pressure sensor under standard conditions can be determined using the first target pressure data and the first action time. The variation coefficient of the pressure sensor under application conditions can be determined using the second target pressure and the second action time. Then, the difference between the two variation coefficients is compared.

[0049] Specifically, in an optional embodiment of the present invention, determining the health status of a pressure sensor based on a first pressure dataset, each first action state, a second pressure dataset, and each second action state includes: determining a periodicity variation factor of the pressure sensor based on the first pressure dataset and each first action state; determining a state discrimination factor of the pressure sensor based on the second pressure dataset and each second action state; and determining the health status of the pressure sensor based on the periodicity variation factor and the state discrimination factor.

[0050] In this embodiment, the periodicity factor can reflect the pressure change of the pressure sensor under standard conditions from when the sensor has not activated to when it has activated. The state discrimination factor can reflect the pressure change of the pressure sensor under application conditions from when the sensor has not activated to when it has activated. The periodicity factor and the state discrimination factor can jointly reflect the health status of the pressure sensor. The health status of the pressure sensor can include pressure sensor healthy status, pressure sensor status warning, and pressure sensor status fault, etc.

[0051] In this step, specifically, the health status of the pressure sensor can be determined by judging whether the periodicity variation factor and the state discrimination factor are the same. For example, if the periodicity variation factor and the state discrimination factor are the same, the pressure sensor can be considered healthy. Alternatively, if the periodicity variation factor and the state discrimination factor are different, but the difference between them does not exceed a user-preset threshold, the pressure sensor can still be considered healthy. Or, if the periodicity variation factor and the state discrimination factor are different, and the difference between them exceeds a user-preset threshold, a warning sign can be issued for the pressure sensor.

[0052] In an optional embodiment of the present invention, determining the health status of a pressure sensor based on a periodicity variation factor and a state discrimination factor includes: if the first target pressure data is the same as the second target pressure data, and the periodicity variation factor and the state discrimination factor are the same, then the health status of the pressure sensor is determined to be that the pressure sensor is in a healthy state; if the first target pressure data is the same as the second target pressure data, and the periodicity variation factor and the state discrimination factor are different, then the health status of the pressure sensor is determined to be that the pressure sensor is in a state warning; otherwise, the health status of the pressure sensor is determined to be that the pressure sensor is in a state fault.

[0053] In this embodiment, the first target pressure data can be the pressure value corresponding to a change in the operating state of the pressure sensor under standard conditions. For example, under standard conditions, when the pressure sensor changes its operation under the pressure of the pressure applying device, the pressure value applied by the pressure applying device at the current moment can be recorded as the first target pressure data. The second target pressure data can be the pressure value corresponding to a change in the operating state of the pressure sensor under application conditions. For example, under application conditions, when the pressure sensor changes its operation under the pressure of the pressure applying device, the pressure value applied by the pressure applying device at the current moment can be recorded as the second target pressure data.

[0054] Specifically, the system first determines whether the first target pressure data and the second target pressure data are the same. If they are the same, the pressure sensor is considered healthy or a pressure sensor status warning is issued, and further judgment is made. If they are different, a pressure sensor status fault is output, and the health status detection for that pressure sensor ends. When the first target pressure data and the second target pressure data are the same, the system continues to determine whether the periodicity variation factor and the status discrimination factor are the same. If the periodicity variation factor and the status discrimination factor are the same, the pressure sensor is considered healthy; if they are different, a pressure sensor status warning is output.

[0055] The advantage of this setup is that by determining whether the first target pressure data and the second target pressure data are the same, the technical means of determining whether the health status of the pressure sensor is a pressure sensor malfunction can be used. When the pressure sensor under test is faulty, the detection steps of the pressure sensor can be reduced, the efficiency of the health status detection of the pressure sensor can be improved, and it is convenient for users to replace or repair the pressure sensor in a timely manner.

[0056] In embodiments of the present invention, the pressure sensor can be automatically detected and alarmed at regular intervals through a systematic language design, which saves costs and makes it convenient for users to obtain the health status of the pressure sensor in a timely manner.

[0057] The technical solution of this embodiment obtains a first pressure dataset applied to the pressure sensor by the pressure applying device under standard conditions, and a first operating state of the pressure sensor corresponding to each data point in the first pressure dataset. It then obtains a second pressure dataset applied to the pressure sensor by the pressure applying device under the application state of the pressure sensor, and a second operating state of the pressure sensor corresponding to each data point in the second pressure dataset. Based on the first pressure dataset, each first operating state, the second pressure dataset, and each second operating state, the health status of the pressure sensor is determined. This solves the problems of inaccurate and unreliable measurement data and untimely anomaly detection that arise from relying on manual measurement to detect the health status of pressure sensors. It reduces the cost of pressure sensor health status detection and improves the reliability of power equipment operation.

[0058] Example 2

[0059] Figure 2 This is a flowchart of another method for detecting the health status of a pressure sensor according to Embodiment 2 of the present invention. This embodiment is a further refinement of the above technical solution, and the technical solution in this embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the method includes:

[0060] Step 210: Obtain the first pressure dataset applied to the pressure sensor by the pressure applying device corresponding to the pressure sensor under standard conditions, and the first operating state of the pressure sensor corresponding to each data in the first pressure dataset.

[0061] Step 220: Obtain the second pressure dataset applied to the pressure sensor by the pressure applying device under the application state of the pressure sensor, and the second operating state of the pressure sensor corresponding to each data in the second pressure dataset.

[0062] Step 230: Determine the first action moment corresponding to the change in the action state of the pressure sensor based on each first action state.

[0063] In this embodiment, the first action moment can be the moment when the pressure sensor reaches the action threshold under standard conditions.

[0064] In this step, specifically, when the pressure sensor reaches the action threshold, the first action state will change, and the current moment can be determined as the first action moment corresponding to the pressure sensor.

[0065] For example, the values ​​0 or 1 can be used to represent each first action state. When the pressure sensor's action state does not change, the corresponding first action state can be assigned a value of 0; when the pressure sensor's action state changes, the corresponding first action state can be assigned a value of 1. When the first action state changes, that is, the value corresponding to the first action state changes from 0 to 1, the corresponding time is the first action time.

[0066] Step 240: Determine the periodic variation factor based on the first action time, the first target pressure data corresponding to the first action time in the first pressure dataset, and the first initial pressure data in the first pressure dataset.

[0067] In this embodiment, the first initial pressure data may be the first pressure data applied to the pressure sensor by the pressure-applying device under the standard state of the pressure sensor.

[0068] In this step, specifically, the periodic variation factor can be calculated over a period of n time intervals based on the pressure applied by the pressure-applying device at time 1 and time n.

[0069] For example, if the operating state of the pressure sensor changes when n=30, the periodicity variation factor can be calculated based on time 1, time 30, and the pressure values ​​corresponding to time 1 and time 30. The periodicity variation factor can then be compared with the state discrimination factor.

[0070] In an optional embodiment of the present invention, determining the periodic variation factor based on the first action time, the first target pressure data corresponding to the first action time in the first pressure dataset, and the first initial pressure data in the first pressure dataset includes: using a formula Determine the periodicity factor; where α is the periodicity factor and n is the first action time; Pa n Pa1 represents the first target pressure data; Pa1 represents the first initial pressure data.

[0071] In this step, specifically, under the standard condition of the pressure sensor, the pressure data Pa applied by the pressure-applying device at time i can be obtained. i Let i = 1, 2, 3, ..., n. When i = 1, the pressure sensor is not activated, and the initial pressure data at the current moment is Pa1. When i = n, the activation state of the pressure sensor changes, and the initial target pressure data at the current moment is Pa. n Then, the periodic variation factor α can be calculated based on the pressure application time and the corresponding pressure data.

[0072] The advantage of this setting is that by selecting the initial moment and the moment when the pressure sensor reaches the action threshold to calculate the period change factor, it can avoid arbitrarily selecting data, which would lead to unreliable results in the health status detection of the pressure sensor, thus improving the reliability of the health status detection of the pressure sensor.

[0073] Step 250: Determine the second action moment corresponding to the change in the action state of the pressure sensor based on each second action state.

[0074] In this embodiment, the second action moment can be the moment when the pressure sensor reaches the action threshold in the application state. For example, the pressure applied to the pressure sensor by the pressure-applying device and the corresponding second action state can be recorded at time 1, time 2, ..., time n. If the action state of the pressure sensor changes at time 94, then time 94 can be considered the second action moment.

[0075] Step 260: Determine the state discrimination factor based on the second action time, the second target pressure data corresponding to the second action time in the second pressure dataset, and the second initial pressure data in the second pressure dataset.

[0076] In this embodiment, the second initial pressure data can be the pressure value first applied to the pressure sensor by the pressure-applying device in the application state. For example, the second initial pressure data can be the pressure value applied to the pressure sensor by the pressure-applying device at the first moment. The value corresponding to the second initial pressure data can be 0.

[0077] In an optional embodiment of the present invention, determining the state discrimination factor based on the second action time, the second target pressure data corresponding to the second action time in the second pressure dataset, and the second initial pressure data in the second pressure dataset includes: using a formula Determine the state discrimination factor; where β is the state discrimination factor; k is the second action time; Pb k Pb1 represents the second target pressure data; Pb1 represents the second initial pressure data.

[0078] In this step, specifically, under the application state of the pressure sensor, the pressure data Pa applied by the pressure-applying device at time j can be obtained. j j = 1, 2, 3, ..., k. When j = 1, the pressure sensor is not activated, and the corresponding initial pressure data at the current moment is Pb1; when j = k, the activation state of the pressure sensor changes, and the corresponding target pressure data at the current moment is Pb. k Then, the state discrimination factor β can be calculated based on the pressure application time and the corresponding pressure data.

[0079] For example, in the application state of the pressure sensor, the pressure data corresponding to the pressure sensor at time 1 can be obtained as 1; at time 80, the operating state of the pressure sensor changes, and the pressure data at this time is 8.6. This can be obtained through the formula... The calculated state discrimination factor is 0.0962.

[0080] The advantage of this setup is that it improves the accuracy of pressure sensor health status detection through explicit value calculations and standardized evaluation processes.

[0081] Step 270: Determine the health status of the pressure sensor based on the periodic variation factor and the state discrimination factor.

[0082] In this step, specifically, the health status of the pressure sensor or the pressure sensor status warning can be determined by judging whether the periodic change factor and the state discrimination factor are equal.

[0083] For example, under the standard state of the pressure sensor, the pressure data corresponding to the pressure sensor at time 1 is 0, and the value corresponding to the first action state is 0; at time 2, the pressure data corresponding to the pressure sensor is 0.1, and the value corresponding to the first action state is 0; at time 3, the pressure data corresponding to the pressure sensor is 0.3, and the value corresponding to the first action state is 0; at time 4, the pressure data corresponding to the pressure sensor is 0.6, and the value corresponding to the first action state is 0; ...; at time 96, the action state of the pressure sensor changes, the value corresponding to the first action state becomes 1, and the pressure data at this time is 9.2. This can be achieved using the formula... The calculated periodicity factor is 0.0958. Under the application state of the pressure sensor, the pressure data corresponding to the pressure sensor at time 1 is 0, and the value corresponding to the second action state is 0; at time 2, the pressure data corresponding to the pressure sensor is 0.1, and the value corresponding to the second action state is 0; at time 3, the pressure data corresponding to the pressure sensor is 0.3, and the value corresponding to the second action state is 0; at time 4, the pressure data corresponding to the pressure sensor is 0.6, and the value corresponding to the second action state is 0; ...; at time 94, the action state of the pressure sensor changes, and the pressure data at this time is 9.2. When the value corresponding to the first action state is 1, the first target pressure data corresponding to the pressure sensor is equal to the value corresponding to the second action state. Therefore, the above health status detection result of the pressure sensor can be considered as either a healthy pressure sensor or a pressure sensor warning. This can be determined using the formula... The calculated state discrimination factor is 0.0989. The periodic change factor is not equal to the state discrimination factor. Therefore, the health status detection result of the pressure sensor is a pressure sensor status warning.

[0084] The technical solution of this embodiment obtains a first pressure dataset applied to the pressure sensor by the pressure applying device under standard conditions, and a first operating state of the pressure sensor corresponding to each data point in the first pressure dataset. It then obtains a second pressure dataset applied to the pressure sensor by the pressure applying device under the application state of the pressure sensor, and a second operating state of the pressure sensor corresponding to each data point in the second pressure dataset. Based on each first operating state, it determines the first operating moment corresponding to a change in the operating state of the pressure sensor. Based on the first operating moment, the first target pressure data corresponding to the first operating moment in the first pressure dataset, and the first initial pressure data in the first pressure dataset, it determines a periodic variation factor. Based on each second operating state, it determines the second operating moment corresponding to a change in the operating state of the pressure sensor. Based on the second operating moment, the second target pressure data corresponding to the second operating moment in the second pressure dataset, and the second initial pressure data in the second pressure dataset, it determines a state discrimination factor. Finally, based on the periodic variation factor and the state discrimination factor, it determines the health status of the pressure sensor. This technical means solves the problems of inaccurate and unreliable measurement data and untimely anomaly detection that arise from relying on manual measurement to detect the health status of pressure sensors. It reduces the cost of pressure sensor health status detection and improves the reliability of power equipment operation.
