[0002] At present, the distributed control system (DCS) is widely used in application scenarios with large-scale real-time control and high reliability requirements, such as petrochemical, chemical, and power production processes, for real-time monitoring and trend analysis of various analog signals involved in the production process. Especially in large nuclear power plants with a capacity of 1 million kilowatt-hours, there are many data acquisition points and data control points, and the control logic is complex and numerous. For important measuring points in nuclear power plants, a redundant design with multiple measurement channels is usually adopted, and a certain value is selected from the signal measurement values obtained from multiple channels as the effective value of the analog signal of the measuring point for the calculation, alarm or display of the control system.

[0003] The existing control system logic configuration adopts the form of building with prefabricated function blocks. After the required function blocks are built, they are downloaded to the controller of the control system and then the configuration takes effect.

[0096] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0097] Embodiment 1

[0098] The method for determining the analog signal in this embodiment is applied to scenarios such as large nuclear power plants. When the distributed control system is applied to the control of a nuclear power plant, a redundant design of pre-setting multiple measurement channels is usually adopted at important measurement points, and the analog signal value of the measurement point is calculated based on multiple measurement data.

[0099] As Figure 1 shown, the method for determining the analog signal in this embodiment includes:

[0100] S101. Select some of the several measurement channels as calculation channels to form a calculation channel group, and use the remaining measurement channels as alternative channels to form an alternative channel group;

[0101] In this embodiment, m measurement channels are selected from N measurement channels as the calculation channel group, and the remaining n measurement channels are used as the alternative channel group, where N = n + m; among them, N, n, and m are all positive integers.

[0102] In an implementable solution, the N measurement channels can also be sorted according to historical quality information, and the m measurement channels with better historical quality information are selected as the calculation channel group, and the remaining n measurement channels are used as the alternative channel group.

[0103] S102. Obtain the calculation channel quality information corresponding to each calculation channel in the calculation channel group;

[0104] In this embodiment, the calculation channel quality information includes but is not limited to the calculation channel measurement information. For example, whether the calculation channel measurement information meets the first preset quality requirement.

[0105] S103. When multiple calculation channel quality information meets the first preset condition, obtain the signal characterization parameter of the analog signal corresponding to the preset measurement point based on the calculation channel quality information;

[0106] In this embodiment, when the m calculation channel quality information of the calculation channel group all meet the first preset condition, the effective measurement value of the analog quantity signal corresponding to the preset measurement point and the data quality code representing the current effective measurement value are determined based on the m calculation channel quality information.

[0107] S104. When multiple pieces of the calculation channel quality information meet the second preset condition, it is determined to update the calculation channel group by using the first quantity of alternative channels in the alternative channel group to obtain a new calculation channel group.

[0108] In this embodiment, when the m calculation channel quality information of the calculation channel group all meet the second preset condition, alternative channels are selected from the n alternative channels for replacement, and the effective measurement value of the analog quantity signal corresponding to the preset measurement point and the data quality code representing the current effective measurement value are determined according to the m calculation channel quality information after replacement.

[0109] S105. Based on the calculation channel quality information of each calculation channel in the new calculation channel group, the signal characterization parameter corresponding to the preset measurement point is calculated.

[0110] In an implementable solution, step S103 includes that the step of calculating the signal characterization parameter of the analog quantity signal corresponding to the preset measurement point based on the calculation channel quality information when multiple pieces of the calculation channel quality information meet the first preset condition includes:

[0111] When the calculation channel quality information of each calculation channel in the calculation channel group all meet the first preset quality requirement, and the deviation value between the calculation channel measurement information of every two calculation channels is less than the first set value, it is determined that the first preset condition is met, as Figure 2 shown, and the first measurement information is calculated based on all the calculation channel measurement information in the calculation channel group.

[0112] Among them, the first measurement information is the mean value or the median value corresponding to all the calculation channel measurement information.

[0113] The first measurement information is used as the effective measurement value of the analog quantity signal of the preset measurement point; and / or, the first data quality characterization information for identifying the data quality information corresponding to the effective measurement value is generated.

[0114] As an alternative implementation, if the quality information of the m computing channels in the computing channel group all meet the first preset quality requirement, and the deviation value between each computing channel and the measured values of the other m - 1 computing channels is less than the set value, then the m computing channels are sorted according to the magnitudes of the measured values. When m = 2, the average of the measured values of the two computing channels is taken as the effective measured value. When m > 2, the median of the m measured values is taken as the effective measured value, and the data quality code is marked as "0", where "0" represents good quality.

[0115] As an alternative implementation, when the quality information of each computing channel in the computing channel group all meet the first preset quality requirement, and the deviation value between the computing channel and the measurement information of the other computing channels is greater than the first set value, and the quality information of each alternative channel in the alternative channel group is lower than the first preset quality requirement, as Figure 2 shown, it is determined that the first preset condition is met, and the signal characterization parameter of the analog quantity signal corresponding to the preset measurement point is calculated based on the computing channel quality information. Specifically:

[0116] The computing channels with deviation values greater than the first preset value from other computing channels are screened out and removed;

[0117] The second measurement information is calculated based on the computing channel measurement information of the remaining computing channels in the computing channel group after the screening process;

[0118] wherein, the second measurement information is the mean or median of the computing channel measurement information of the remaining computing channels;

[0119] The second measurement information is taken as the effective measured value of the analog quantity signal at the preset measurement point; and / or, a second data quality characterization information for representing the data quality information corresponding to the effective measured value is generated.

[0120] Specifically, among the m computing channels in the computing channel group, there are m1 computing channels with deviation values greater than the preset value from other computing channels. Assuming m1 < m, then the remaining (m - m1) computing channels are sorted according to the magnitudes of the measured values. When the number of remaining computing channels is 2, the average of the measured values is taken as the effective measured value. When the number of remaining computing channels is greater than 2, the median of the measured values of the remaining computing channels is taken as the effective measured value, and the data quality code is marked as "0".

[0121] Assuming m1 = m, that is, the deviation value of each computing channel from other computing channels is greater than the set value, then the measurement results of the m computing channels this time are discarded, and the effective measured value of the previous time is taken as the effective measured value of this measurement, and the data quality code is marked as "1", where "1" represents poor quality.

[0122] In an implementable solution, step S104 includes that when the computing channel quality information of each computing channel in the computing channel group meets the first preset quality requirement, the deviation value between the computing channel measurement information of the computing channel and that of other computing channels is greater than the first set value, and the quality information of the alternative channels in the alternative channel group meets the first preset quality requirement, and the deviation value between the alternative channel measurement information of the alternative channels and the computing channel measurement information of other computing channels is less than the first set value, it is determined that the second preset condition is met, and the computing channel group is updated with the alternative channels in the alternative channel group to obtain a new computing channel group;

[0123] Or,

[0124] When the computing channel quality information of the computing channels in the computing channel group is lower than the first preset quality requirement, and the alternative channel quality information of the alternative channels in the alternative channel group meets the first preset quality requirement, it is determined that the second preset condition is met, as Figure 3 shown, and the computing channel group is updated with the alternative channels in the alternative channel group to obtain a new computing channel group.

[0125] Specifically, among the m computing channels in the computing channel group, there are m1 computing channels with a deviation value greater than the first preset value from other computing channels, and there are m2 computing channels with quality information lower than the first preset quality requirement. If there are alternative channels in the alternative channel group with a deviation value less than the first set value from the measurement values of the m computing channels, it is determined that the second preset condition is met, and the computing channel group is updated with the alternative channels that meet the conditions to obtain a new computing channel group.

[0126] In an implementable solution, step S105 specifically includes:

[0127] Screen out and eliminate the computing channels in the computing channel group with computing channel quality information lower than the first preset quality requirement;

[0128] Screen out and eliminate the computing channels with a deviation value greater than the first set value from other computing channels;

[0129] Calculate the third measurement information based on the computing channel measurement information of the remaining computing channels in the computing channel group;

[0130] wherein, the third measurement information is the mean value or median value corresponding to the computing channel measurement information of the remaining computing channels or the historical measurement value generated in the previous determination process;

[0131] Use the third measurement information as the effective measurement value of the analog signal at the preset measurement point; and / or generate fourth data quality characterization information for representing the data quality information corresponding to the effective measurement value.

[0132] Specifically in this embodiment, after screening out m2 calculation channels with the quality information of the calculation channels lower than the first preset quality requirement, further screen out the calculation channels with the deviation value from other calculation channels greater than the first set value among the remaining (m - m2) calculation channels, calculate based on the measurement information of the remaining calculation channels, use the median value or average value or the previous historical measurement value of the measurement values of the remaining calculation channels as the effective measurement value, and generate the corresponding data quality code.

[0133] The working principle of the method for determining the analog signal proposed by the present invention will be specifically described below with reference to examples:

[0134] When the distributed control method is applied to the monitoring of large nuclear power plants, for important measurement points, a redundant design with four measurement channels is usually adopted, as Figure 4 shown. Analog signals 1 to 4 are the analog signals to be measured at the preset measurement point, and the card channel is the data acquisition device set at the preset measurement point, corresponding to the four measurement channels in the present invention respectively, and is used to convert the received analog signal into a digital signal and input it into the controller of the distributed control system for data processing. The controller calculates based on the received measurement channel quality information to determine the signal characterization parameters of the analog signal at the preset measurement point, including the effective measurement value of the current measurement point and the data quality code representing the data quality information, which are used for subsequent calculations or displays of the control system. When the quality of the measurement channel is lower than the preset requirement or the deviation value between two measurement channels exceeds the set value, corresponding fault alarms will be generated.

[0135] In this embodiment, the first three measurement channels are used as the calculation channels, and the measurement values are respectively denoted as A1, A2, and A3. The remaining channels are the alternative channels, and the measurement value of the alternative channel is denoted as C1. When the quality information of the collected analog signal meets the first preset quality requirement, it is marked as "0", representing good data quality, otherwise it is marked as "1", representing poor data quality.

[0136] This embodiment will illustrate how to determine the signal characterization parameters of the analog signal when the quality marks of the three calculation channels are all good.

[0137] First, calculate the deviation values |A1 - A2|, |A2 - A3|, and |A1 - A3| of the measurement values of the three channels, and determine whether the three deviation values are within the set value range. Here, the set value is set as D. When the deviation value is less than D, it is determined that the first preset condition is met.

[0138] Arrange A1, A2, and A3 in ascending order, take the median value of the sequence as the effective measurement value of this measuring point, and mark the data quality code as "0".

[0139] When the three deviation values exceed the set value D, then make a judgment based on the alternative channel quality information. When the alternative channel quality is marked as poor, the first preset condition is satisfied, and calculate according to the quality information of the three calculation channels. Specifically

[0140] When one of the three deviation values |A1 - A2|, |A2 - A3|, |A1 - A3| is less than the set value D, assume |A1 - A3| is less than the set value, then take the average value of A1 and A3 as the measurement value of this measuring point, and mark the data quality code as "0";

[0141] When all of the three deviation values |A1 - A2|, |A2 - A3|, |A1 - A3| are greater than the set value D, that is, the deviation of the three measurement channel values is too large, then it is considered that this measurement process is invalid. Take the historical measurement value determined in the previous acquisition process as the effective measurement value of this measuring point, output a fault alarm signal, and mark the data quality code as "1".

[0142] In this embodiment, a plurality of measurement channels set at the preset measuring point are divided into a calculation channel group and an alternative channel group. Whether to use an alternative channel for replacement is determined according to the quality information and deviation values of the multiple calculation channels in the calculation channel group. The analog signal characterization parameters determined by this method can truly and effectively reflect the signal quality of the current measuring point, have higher accuracy and reliability, and can adapt to different scenarios, and can be used without modification and debugging, effectively saving labor and time costs.

[0145] Among them, the quality information acquisition module 210 is used to acquire the quality information of all measurement channels set at the preset point, and the measurement channels include a calculation channel group and an alternative channel group.

[0146] The deviation value acquisition module 220 is used to calculate the deviation values between the measurement values of every two calculation channels in the calculation channel group according to the measurement information of the calculation channel group.

[0147] The alternative replacement logic module 230 is used to determine whether it is necessary to use the alternative channels in the alternative channel group for replacement according to the quality information of the calculation channels in the calculation channel group.

[0148] The alternative channel replacement module 240 is used to select an alternative channel to replace the calculation channel of the calculation channel group and update it to a new calculation channel group for calculation when the calculation channel quality information of the calculation channel group meets the second preset condition.

[0149] The alternative channel removal module 250 is used to calculate according to the calculation channel group before the alternative channel replacement when the quality information of the calculation channel group before the alternative channel replacement meets the first preset condition after the alternative channel updates the calculation channel group and the signal characterization parameters are calculated based on the new calculation channel group.

[0150] The signal characterization parameter determination module 260 is used to obtain the signal characterization parameters of the analog signal according to the calculation channel quality information of the new calculation channel group, including the effective measurement value of the analog signal and the data quality characterization information.

[0151] In an implementable solution, the alternative replacement logic module 230 includes a first detection unit 231 and a second detection unit 232.

[0152] The first detection unit 231 is used to calculate the signal characterization parameters of the analog signal based on the calculation channel quality information of the calculation channel group when the calculation channel quality information meets the first preset condition.

[0153] In an implementable solution, the first detection unit is used to use the mean or median value corresponding to all the calculation channel measurement information as the effective measurement value of the analog signal at the preset measurement point when the calculation channel quality information of each calculation channel in the calculation channel group meets the first preset quality requirement and the deviation value between every two calculation channel measurement information is less than the first set value; and / or, generate a data quality code for identifying the data quality information corresponding to the effective measurement value.

[0154] In another implementable solution, the first detection unit is further used when the calculation channel quality information of each calculation channel in the calculation channel group meets the first preset quality requirement, the deviation value between the calculation channel and the measurement information of other calculation channels is greater than the first set value, and the quality information of each alternative channel is lower than the first preset quality requirement;

[0155] Or, when the calculation channel quality information in the calculation channel group is lower than the first preset quality requirement and the quality information of the alternative channels in the alternative channel group is lower than the first preset quality requirement, the first detection unit calculates based on the calculation channel quality information.

[0156] Specifically: screen out the calculation channels with deviation values greater than the first preset value from other calculation channels and eliminate them;

[0157] Or,

[0158] Filter out the computing channels whose computing channel quality information is lower than the first preset quality requirement and eliminate them;

[0159] The first detection unit calculates based on the computing channel measurement information of the remaining computing channels after the screening process, and takes the mean or median value corresponding to the computing channel measurement information of the remaining computing channels as the effective measurement value of the analog signal; and / or, generates a data quality code for representing the data quality information corresponding to the effective measurement value.

[0160] Preferably, when the computing channel deviation values are all greater than the first preset value, or the computing channel quality information is all lower than the first preset quality requirement, obtain the historical measurement value generated in the previous determination process;

[0161] Take the historical measurement value as the effective measurement value of the analog signal of the preset measuring point; and / or, generate a data quality code for representing the data quality information corresponding to the effective measurement value.

[0163] In an implementable solution, after the alternative channel is replaced, the second detection unit is further used to call the alternative channel removal module for processing when the computing channel group quality information before the alternative channel replacement meets the first preset condition.

[0165] Or

[0166] When there is a computing channel in the computing channel group whose computing channel quality information is lower than the first preset quality requirement, and the quality information of the alternative channels in the alternative channel group meets the first preset quality requirement, it is determined that the second preset condition is met, and the alternative channel replacement module is called for processing.

[0167] The alternative channel replacement module 240 is used to replace the computing channels of the computing channel group with alternative channels when the computing channel quality information of multiple computing channels in the computing channel group meets the second preset condition, and update to obtain a new computing channel group.

[0168] In an implementable solution, the alternative channel replacement module is used to replace the calculation channel with a large deviation value with an alternative channel to obtain a new calculation channel group when the deviation value between the calculation channel measurement information and other calculation channel measurement information is greater than a first set value, the alternative channels in the alternative channel group meet the first preset quality requirement, and the deviation value between the alternative channel and other calculation channel measurement information is less than the first set value.

[0170] In an implementable solution, the alternative channel replacement module further includes a counter unit 241 for recording the number of times the alternative channel is replaced. The initial value of the timer is set to 0. Each time the alternative channel is replaced, the counter is incremented by 1. When the counter reaches a second set value, the alternative channel will not be replaced and the counter is restored to the initial value 0.

[0171] The signal characterization parameter determination module 260 is used to obtain the signal characterization parameters of the analog signal according to the quality information of the new calculation channel group, including the effective measurement value of the analog signal and the data quality characterization information. Specifically:

[0172] The signal characterization parameter determination module 260 is used to screen out and eliminate the calculation channels in the calculation channel group with quality information lower than the first preset quality requirement;
