[0002] The existing anti-jump processing method of measured value usually lengthens the logic output delay to cross the entire jump period to avoid accidental measured value jumps and cause erroneous output.

[0025] Embodiments of the present application are described in detail below, and 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 to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The following describes the anti-jump method and device for the analog measurement value of a hydropower plant according to an embodiment of the present application with reference to the accompanying drawings.

[0027] Figure 1 is a flow chart of a method for preventing jump changes in analog measurement values ​​of a hydropower plant provided in an embodiment of the present application, such as Figure 1 As shown, the anti-jump method of the hydropower plant analog measurement value in the embodiment of the present application includes but is not limited to the following steps:

[0028] S101, monitoring the analog quantity of the hydropower plant based on a set sampling period to obtain the measured value of the analog quantity.

[0029] It should be noted that the execution subject of the anti-jump method of the hydropower plant analog measurement value provided in the embodiment of the present application is an electronic device, and the electronic device can be a terminal device. Optionally, the terminal device can be a mobile electronic device or a non-mobile electronic device. Exemplarily, the mobile electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal digital assistant (personal digital assistant, PDA), etc., and the non-mobile electronic device can be a personal computer (personal computer, PC), a television, etc. The embodiment of the present application is not specifically limited.

[0030] In some implementations, analog quantities refer to physical quantities that can change continuously. These physical quantities are usually converted into analog signals by sensors or other measuring devices, which can then be collected and processed. The analog quantities of a hydropower plant can reflect the operating status and parameters of the hydropower plant equipment. The analog quantities of a hydropower plant include electrical analog quantities and non-electrical analog quantities.

[0031] In some implementations, multiple sensors and data acquisition systems can be used to monitor analog quantities of a hydropower plant, and obtain the measured values ​​of the analog quantities according to a set sampling period. The sampling period is configured in the data acquisition system, and data acquisition instructions are sent to the sensor according to the sampling period, so that the sensor collects the measured values ​​of the analog quantities.

[0032] S102: For any measured value, obtain a marking state of any measured value, and a change rate and a change value of any measured value within a sampling period.

[0033] In some implementations, the change rate and change value of any measured value within a sampling period can be calculated based on the size of any measured value. Then, the marking state of any measured value can be obtained based on the identification information of any measured value. The marking state is divided into a trusted state and an untrusted state.

[0034] For example, if the identifier corresponding to the credible state is A and the identifier corresponding to the uncredible state is B, if the identifier of any measured value is A, then the marking state of the measured value is determined to be the credible state.

[0035] Optionally, the marking state of any measured value may be determined according to a preset marking rule. The marking state of the measured value may be obtained by accessing a database storing the measured values.

[0036] Optionally, the rate of change of any measured value can be obtained by calculating the difference between any measured value and the measured value of the previous sampling point and dividing it by the time interval of the sampling period, and the change value of any measured value can be obtained by calculating the difference between any measured value and the measured value of the previous sampling point within the sampling period.

[0037] S103, based on the mark state, the change rate and the change value, anti-jump processing is performed on any measured value.

[0038] In some implementations, the measurement value can be determined to be in a credible state or an untrusted state based on the mark state, and then the measurement value can be anti-jump processed based on the change rate and change value of the measurement value, as well as the change rate threshold corresponding to the change rate and the valid interval corresponding to the change value.

[0039] It is understandable that in the process of monitoring the hydropower plant, the anti-jump processing of the measured value mainly refers to taking measures to prevent or reduce the phenomenon of drastic fluctuations or jumps in the analog measurement value in a short period of time. Such jumps may be caused by a variety of reasons such as sensor failure, electromagnetic interference, data transmission errors, etc. Anti-jump processing helps to improve the accuracy and reliability of data, thereby ensuring the safe operation and efficient management of the hydropower plant.

[0040] In some implementations, when it is determined that any measured value is in a credible state, it is determined whether the change value of any measured value is within a valid interval, and the change rate is further determined for any measured value within the valid interval. If the change rate of any measured value is less than the change rate threshold, it can be determined that there is no jump in any measured value, and any measured value can be stored for subsequent logical actions, otherwise, the mark state of any measured value is modified to an untrustworthy state.

[0041] In some implementations, when it is determined that any measured value is in an untrustworthy state, it can be determined whether to cancel the untrustworthy mark of any measured value based on the change value of any measured value in the current sampling period and the change value in the subsequent sampling period.

[0042] Optionally, if the change value of any measured value in the current sampling period is within the valid interval, and the change values ​​in subsequent sampling periods are all within the valid interval, the marking state of any measured value can be modified to a trusted state. Otherwise, any measured value is determined to be a jump measurement value to prevent the measured value from performing subsequent logical actions, thereby realizing anti-jump processing of the measured value.

[0043] In some implementations, when any measurement value is determined to be a jump measurement value, an alarm operation can also be performed according to the alarm threshold. If the jump measurement value is greater than the upper limit of the alarm threshold, or the jump measurement value is less than the lower limit of the alarm threshold, the alarm operation is triggered to provide timely warning and response to the hydropower plant.

[0044] In some implementations, the above anti-jump processing process can be written as a program code, and the program code can be added to the computer monitoring system of the hydropower plant. Since the program code is easy to write, readable and extensible, the anti-jump processing process can be made without sacrificing logical sensitivity, and the logic is more concise. By adding the program code to the program segment of the local control unit of the computer monitoring system, real-time monitoring and anti-jump processing of the measured values ​​of the hydropower plant can be achieved.

[0045] In the anti-jump method for the analog quantity measurement value of a hydropower plant provided in the embodiment of the present application, by obtaining the measured value of the analog quantity of the hydropower plant within a sampling period, and based on the marking state of the measured value, the change rate and the change value of the measured value within the sampling period, the measured value can be anti-jump processed, which can avoid the risk of logical error output and equipment malfunction caused by the jump of the measured value, enhance the stability of the monitoring system, and ensure data quality.

[0046] Figure 2 is a flow chart of a method for preventing jump changes in analog measurement values ​​of a hydropower plant provided in an embodiment of the present application, such as Figure 2 As shown, the anti-jump method of the hydropower plant analog measurement value in the embodiment of the present application includes but is not limited to the following steps:

[0047] S201, monitoring the analog quantity of the hydropower plant based on the set sampling period to obtain the measured value of the analog quantity.

[0048] In the embodiment of the present application, the implementation method of step S201 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0049] S202: For any measured value, obtain a marking state of any measured value, and a change rate and a change value of any measured value within a sampling period.

[0050] In the embodiment of the present application, the implementation method of step S202 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0051] S203: If the marking state is a credible state, determine whether the change value of any measured value is within a valid range, and determine whether the change rate of any measured value is less than a change rate threshold.

[0052] In some implementations, when the mark state is determined to be a trusted state, it is possible to determine whether the change value of any measured value is within the valid interval based on the change value of any measured value and the valid interval corresponding to the change value, and to determine whether the change rate of any measured value is less than the change rate threshold based on the change rate of any measured value and the change rate threshold corresponding to the change rate.

[0053] S204, in response to the change value being within the valid interval and the change rate being less than the change rate threshold, any measured value is stored for use in determining the logical action of the hydropower station, otherwise, the marking state is changed to an untrustworthy state.

[0054] In some implementations, if the change value of any measured value is within the valid range, and it is continued to be determined whether the change rate of any measured value is less than the change rate threshold, if the change rate of any measured value is less than the change rate threshold, it can be determined that any measured value is not a jump measurement value, and then any measured value can be stored for determining the logical action of the hydropower station.

[0055] In some implementations, if the change value of any measured value is not within the valid interval, the marking state of any measured value is changed to an untrustworthy state. Alternatively, if the change value of any measured value is within the valid interval, but the change rate of any measured value is greater than the change rate threshold, the marking state of any measured value is changed to an untrustworthy state.

[0056] In the anti-jump method for the analog quantity measurement value of a hydropower plant provided in the embodiment of the present application, by obtaining the measured value of the analog quantity of the hydropower plant within a sampling period, and obtaining the marking status of the measured value, the change rate of the measured value within the sampling period and the change value, if the measured value is determined to be in a credible state, it can be determined whether the change value of the measured value is within a valid range, and whether the change rate is less than the change rate threshold, thereby realizing anti-jump processing on the measured value, which can avoid the risk of logical error output and equipment malfunction caused by measured value jumps, enhance the stability of the monitoring system, and ensure data quality.

[0057] Figure 3 is a flow chart of a method for preventing jump changes in analog measurement values ​​of a hydropower plant provided in an embodiment of the present application, such as Figure 3 As shown, the anti-jump method of the hydropower plant analog measurement value in the embodiment of the present application includes but is not limited to the following steps:

[0058] S301, monitoring the analog quantity of the hydropower plant based on the set sampling period to obtain the measured value of the analog quantity.

[0059] In the embodiment of the present application, the implementation method of step S301 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0060] S302: For any measured value, obtain a marking state of any measured value, and a change rate and a change value of any measured value within a sampling period.

[0061] In the embodiment of the present application, the implementation method of step S302 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0062] S303: If the marked state is an untrustworthy state, obtain a candidate change value of any measured value within n consecutive sampling periods.

[0063] S304: Based on the change value and the candidate change value, perform anti-jump processing on any measured value.

[0064] In some implementations, when the mark state is determined to be an untrustworthy state, the candidate change value of any measured value within n consecutive sampling cycles can be obtained to perform anti-jump processing on any measured value based on the candidate change value, change value and valid interval.

[0065] In some implementations, by determining whether the change value is within the valid interval, if it is within the valid interval, continue to determine whether the candidate change value is within the valid interval. That is, first determine whether the change value of any measured value is within the valid interval in the current sampling period, if it is, then continue to determine whether the change value of any measured value is within the valid interval in n consecutive sampling periods; if not, determine that any measured value is a jump measured value.

[0066] Optionally, in response to the candidate change value being within the valid interval, any measured value is marked as a credible state; in response to the candidate change value not being within the valid interval, any measured value is marked as a jump measured value to prevent the measured value from performing subsequent logical actions, thereby implementing anti-jump processing of the measured value.

[0067] In some implementations, when any measurement value is determined to be a jump measurement value, an alarm operation can also be performed according to the alarm threshold. If the jump measurement value is greater than the upper limit of the alarm threshold, or the jump measurement value is less than the lower limit of the alarm threshold, the alarm operation is triggered to provide timely warning and response to the hydropower plant.

[0068] In the anti-jump method for the analog quantity measurement value of a hydropower plant provided in the embodiment of the present application, the measured value of the analog quantity of the hydropower plant within a sampling period is obtained, and the marking status of the measured value, the rate of change of the measured value within the sampling period and the change value are obtained. If the measured value is in an unreliable state, it is determined whether the change value is within a valid range, and whether it is also within a valid range in subsequent sampling periods, so as to implement anti-jump processing on the measured value, avoid the risk of logical error output and equipment malfunction caused by measured value jumps, enhance the stability of the monitoring system, and ensure data quality.

[0069] like Figure 4The flowchart of the measured value anti-jumping is shown. By obtaining the measured value of the analog quantity of the hydropower plant, and performing anti-jumping processing on all N measured values, for the i-th measured value, by obtaining the marking status of the i-th measured value, and judging whether the i-th measured value is in an untrustworthy state, if it is not in an untrustworthy state, then obtaining the change value of the i-th measured value, and judging whether the change value is in a valid range, if it is, then continue to judge whether the change rate of the i-th measured value is less than the change rate threshold, otherwise mark the i-th measured value as an untrustworthy state. If the change rate of the i-th measured value is less than the change rate threshold, then cache the i-th measured value, and continue to perform anti-jumping processing on the i+1th measured value, until the measured values ​​of the N analog quantities are processed, and the measured value acquisition and anti-jumping processing are performed again. Wherein, N is a natural number greater than 2, and i is greater than or equal to 1 and less than or equal to N.

[0070] If the i-th measured value is in an untrusted state, obtain the change value of the i-th measured value, and determine whether the change value is in the valid interval. If it is, continue to obtain the candidate change value of the i-th measured value in n consecutive sampling periods, and determine whether the candidate change value is in the valid interval; if not, treat the i-th measured value as a jump measured value. If all candidate change values ​​are in the valid interval, cancel the untrusted mark of the i-th measured value, and continue to perform anti-jump processing on the i+1th measured value until the measured values ​​of N analog quantities are processed, and re-acquire the measured values ​​and perform anti-jump processing.

[0071] Based on the above embodiments, the embodiments of the present application can explain the anti-jump process of the initialization measurement value, such as Figure 5 As shown, the anti-jump process of the initialization measurement value in the embodiment of the present application includes but is not limited to the following steps:

[0072] S501, obtain the measured value of each analog quantity and set the effective range of the measured value.

[0073] In some implementations, in order to ensure the accuracy of the measured value anti-jump processing process, the anti-jump process can be initialized before the measured value is anti-jumped. The anti-jump process can be initialized according to the effective interval of the measured value. The measured value of each analog quantity of the hydropower plant is obtained, and the effective interval of the measured value is determined.

[0074] Optionally, the effective interval of the measured values ​​can be obtained based on historical data. The effective interval of the measured values ​​is determined by obtaining the sizes of multiple measured values ​​from historical data, obtaining the maximum measured value and the minimum measured value from the multiple measured values, and calculating the maximum measured value and the minimum measured value. In other words, the maximum measured value can be used as the upper limit of the effective interval of the measured values, and the minimum measured value can be used as the lower limit of the effective interval of the measured values.

[0075] S502, based on the measured value and the effective interval of the measured value, initialize the anti-jump process of the measured value.

[0076] In some implementations, it can be determined whether the measured value is within the effective interval of the measured value, and then the measured value can be marked as a state to initialize the anti-jump process of the measured value. Optionally, for the measured value i, the measured value i is marked as an untrustworthy state, and it is determined whether the measured value i is within the effective interval of the measured value.

[0077] Further, in response to the measured value i being within the measured value valid interval, the flag state of the measured value i is reset, and it is continuously determined whether the measured value i+1 is within the measured value valid interval, until the flag state of each measured value is reset, and the initialization is terminated.

[0078] In the anti-jump method for the analog measurement value of a hydropower plant provided in the embodiment of the present application, the measured value of each analog quantity is obtained, and the effective interval of the measured value corresponding to the measured value is determined, so as to initialize the anti-jump process according to the measured value size and the effective interval of the measured value. The initialization process can ensure that the measured values ​​of all analog quantities have a known and reasonable state when the anti-jump is executed, avoiding the collapse of the anti-jump process due to uninitialized measured values. In the anti-jump process, initialization can ensure that the measured value will not be affected by the previous sampling or undefined state when it is first collected, thereby improving the accuracy of the data.

[0079] like Figure 6 The flowchart of the process of preventing jumps of the initialization measurement value is shown in FIG. The measurement value of the hydropower plant is obtained, and it is determined whether the measurement value i is within the effective measurement value interval. If it is within the effective measurement value interval, the measurement value i is cached, and the mark state of the measurement value i is reset, and the measurement value i+1 is continuously obtained, and it is determined whether the measurement values ​​are initialized, and the initialization process is terminated. Otherwise, the measurement value i+1 is continuously obtained, and the measurement value initialization process is continued.

[0080] Corresponding to the anti-jumping methods for analog measurement values ​​of hydropower plants proposed in the above-mentioned embodiments, an embodiment of the present application further proposes an anti-jumping device for analog measurement values ​​of hydropower plants. Since the anti-jumping device for analog measurement values ​​of hydropower plants proposed in the embodiment of the present application corresponds to the anti-jumping methods for analog measurement values ​​of hydropower plants proposed in the above-mentioned embodiments, the implementation method of the above-mentioned anti-jumping method for analog measurement values ​​of hydropower plants is also applicable to the anti-jumping device for analog measurement values ​​of hydropower plants proposed in the embodiment of the present application, and will not be described in detail in the following embodiments.

[0081] In order to implement the above-mentioned embodiment, the present application also proposes an anti-jump device for analog measurement values ​​of a hydropower plant.

[0082] Figure 7 A schematic diagram of the structure of an anti-jump device for analog measurement values ​​of a hydropower plant provided in an embodiment of the present application.

[0083] like Figure 7As shown, the anti-jump device 700 of the analog measurement value of the hydropower plant includes:

[0084] The monitoring module 701 is used to monitor the analog quantity of the hydropower plant based on a set sampling period and obtain the measured value of the analog quantity;

[0085] The acquisition module 702 is used to acquire, for any measured value, a marking state of the measured value, and a change rate and a change value of the measured value within the sampling period;

[0086] The anti-jump module 702 is used to perform anti-jump processing on any of the measured values ​​based on the flag state, the change rate and the change value.

[0087] In a possible implementation of an embodiment of the present application, the anti-jump module 702 is also used to: if the mark state is a trusted state, determine whether the change value of any measured value is within a valid range, and determine whether the change rate of any measured value is less than a change rate threshold; in response to the change value being within the valid range and the change rate being less than the change rate threshold, store any measured value for determining the logical action of the hydropower station, otherwise, change the mark state to an untrustworthy state.

[0090] In a possible implementation of the embodiment of the present application, the anti-jump module 702 is further used to: obtain the measured value of each analog quantity and set the measured value valid interval; and initialize the anti-jump process of the measured value based on the measured value and the measured value valid interval.

[0091] In a possible implementation manner of the embodiment of the present application, the anti-jump module 702 is further used to: for the measured value i, mark the measured value i as an untrustworthy state, and determine whether the measured value i is within the measured value valid interval; in response to the measured value i being within the measured value valid interval, reset the mark state of the measured value i, and continue to determine whether the measured value i+1 is within the measured value valid interval, until the mark state of each measured value is reset, and the initialization is ended.

[0092] In the anti-jump device for the analog quantity measurement value of the hydropower plant provided in the embodiment of the present application, by obtaining the measured value of the analog quantity of the hydropower plant within a sampling period, and according to the marking state of the measured value, the rate of change of the measured value within the sampling period and the change value, the measured value can be anti-jump processed, which can avoid the risk of logical error output and equipment malfunction caused by the jump of the measured value, enhance the stability of the monitoring system and ensure the data quality.
