[0003] The DCS (Distributed Control System) is the control and information central nervous system of a nuclear power plant, providing various control and protection information to ensure reliable, stable, and economical operation. Due to the complexity of nuclear power plant processes, the large number of devices, and the enormous number of measurement signals, rationally distributing these signals across different control stations and I / O (Input / Output) cards is quite challenging. A 1000MW nuclear power unit involves over 10,000 hardwired I / O measurement points. Assigning these points row by row using an Excel spreadsheet would be extremely labor-intensive and prone to errors. Summary of the Invention

[0043] DCS system I / O allocation mainly consists of two aspects: first, the functional allocation of the control station, which assigns various control functions of the power plant to controllers and determines the number of controllers; second, the allocation of I / O channels (at this point, the I / O measurement points within the control station are already defined). A controller station may have one or more DCS cabinets, and measurement points are allocated to different I / O modules in different cabinets under that controller according to the I / O type. Based on this, this application provides an automatic I / O measurement point allocation method to solve the I / O channel allocation problem and realize the automatic allocation of I / O to various I / O modules in different cabinets.

[0044] Figure 1 is a flowchart of an automatic I / O measurement point allocation method provided in an exemplary embodiment of this application. The automatic I / O measurement point allocation method includes the following steps:

[0045] S11. Divide the I / O measurement points into several functional groups according to their signal functions.

[0046] The functions of the I / O signals at the I / O measurement points include, but are not limited to, on / off, alarm, and fault.

[0047] In one embodiment, I / O measurement points are divided into several functional groups based on their signal functions, including:

[0048] I / O measurement points whose signal function correlation is greater than the correlation threshold are classified into the same functional group;

[0049] I / O measurement points with redundant or parallel signal functions within the same functional group are classified into different branches of the same functional group.

[0050] The associated threshold is set according to the actual situation.

[0051] I / O measurement points have I / O signals. Functionally related I / O signals are grouped into the same functional group. For example, I / O signals belonging to the same device are grouped into the same functional group. The same functional group includes multiple branches. Functionally redundant or parallel I / O signals are grouped into different branches of the same functional group. For example, if one I / O signal describes the opening command of the pneumatic check valve of the heating extraction steam header, and another I / O signal describes the high oil temperature alarm of the hydraulic quick-closing regulating valve of the heating extraction steam header, then the two I / O signals belong to different branches of the same functional group.

[0052] S12. Encode the I / O measurement points of the same functional group to obtain the I / O measurement point list.

[0053] A functional group includes multiple I / O measurement points. Each I / O measurement point in each functional group is encoded to obtain an I / O measurement point list that includes the signal name, signal type, and functional group code of the I / O measurement point. The I / O measurement point list includes, but is not limited to, the signal name, signal type, and functional group code of the I / O measurement point.

[0054] In one embodiment, I / O test points for the same functional group are encoded to obtain an I / O test point list, including:

[0055] Based on the location of the functional group at its respective controller site and the branch type of the signal function of the I / O measurement point, the I / O measurement points are coded to obtain the I / O measurement point list.

[0056] The power plant includes multiple controllers, and various control functions are assigned to each controller. Each control function is controlled by I / O measurement points. The I / O measurement points are coded according to the location of their functional group at their respective controller site and the branch type of their signal function. For example, when the functional group is the first functional group at the controller site, one bit of the code is 1. When the branch type of the I / O measurement point's signal function is a non-redundant branch, and different branches of the same functional group are preferentially assigned to different cards, one bit of the code is F. In this case, the code of the I / O measurement point is 1.F1.

[0057] In one embodiment, the encoding of the I / O measurement point includes a first encoding and a second encoding. The first encoding is determined based on the location of the functional group at its respective controller site, and the second encoding is determined based on the branch type of the signal function of the I / O measurement point.

[0058] Based on the location of the functional group at the controller site and the branch type of the signal function of the I / O measurement point, the I / O measurement points are coded, including:

[0059] In response to the branch type being redundant and different branches of the same functional group not being assigned to the same I / O card, the second code is determined to be the first category;

[0060] In response to the branch type being parallel and different branches of the same functional group not being assigned to the same I / O card, the second code is determined to be the second category;

[0061] In response to the branch type being parallel and different branches of the same functional group being preferentially assigned to the same I / O card, the second code is determined to be the third category.

[0062] As shown in Figure 2, the I / O measurement points in each functional group are coded. The coding format for each functional group is x.Zy or Ox. Here, x is the first code, a positive integer representing the functional group number, determined by the functional group's location at its respective controller station. For example, x = 1 indicates the first functional group assigned to that station. Z represents the branch type. For instance, Z = R indicates a redundant branch type, and different branches of the same functional group cannot be placed on the same card. Z = BF indicates a non-redundant branch, and different branches of the same functional group cannot be placed on the same card. Z = F indicates a non-redundant branch, and different branches of the same functional group are preferentially assigned to different cards. Z = T indicates signals belonging to the same device within the same functional group, and are preferentially placed in the same cabinet and the same card. If a functional group has no branches, Zy can be omitted. y represents the branch code of a functional group. O indicates that the signal is used for process monitoring or alarm functions and does not directly participate in control. x represents the code of the process monitoring or alarm function group. When it is necessary to allocate process monitoring or alarm signals in the same cabinet or the same card, the x in Ox uses the function group number x.

[0063] In one embodiment, I / O test points for the same functional group are encoded to obtain an I / O test point list, including:

[0064] Encode the same I / O measurement point at least three times, following the functional hierarchy of the signal from largest to smallest.

[0065] When allocating functions for control stations, some less important branch control functions may be arranged in the same control station due to the limited number of control stations. When branch control functions are allocated in the same control station and there are branch control functions inside, multi-level coding is required.

[0066] Considering that the more encoding levels there are, the more complex the algorithm implementation becomes, in order to simplify the calculation, the automatic allocation method for I / O measurement points provided in this application encodes according to three levels. As shown in Figure 3, the encoding adopts a method from large to small and from top to bottom. When there is a branch control function in the first-level control loop, the second-level encoding is performed on the basis of the first-level encoding to form the second-level control loop. When there is a branch control function in the second-level control loop, the third-level encoding is performed on the basis of the second-level encoding to form the third-level control loop. That is, according to the functional level of the signal function from large to small, the same I / O measurement point is encoded at least three times.

[0067] S13. Automatically assign I / O measurement points to I / O cards according to the codes in the I / O measurement point list.

[0068] When the I / O measurement points within a control station are defined, a controller station may have one or more DCS cabinets. Based on the functional type of the I / O measurement points, the I / O measurement points are assigned to different I / O modules, i.e., different I / O cards, in different cabinets under that controller.

[0069] In one embodiment, automatically assigning I / O test points to I / O cards based on the codes in the I / O test point list includes:

[0070] For the same I / O test point, the I / O test points are automatically assigned to I / O cards according to their coding level, from smallest to largest.

[0071] Input the coded I / O measurement point list into the computer system. The I / O measurement point list includes the signal name, signal type, and function group code of each I / O measurement point. Input the card type of the selected I / O and the required margin for each card. Write Python code to parse the code of each function group. First, according to the number of the first-level function group, divide it into several combinations according to the permutation and combination method in mathematics. Iterate through each combination and obtain the allocation result of each combination method. Among them, the function group code specifies the constraints for allocation. Taking three coding levels as an example, the allocation between levels should be carried out in the order of the third level, the second level, and the first level, because the first level contains the constraints of the second and third levels. The more constraints, the more complex it is. The second level is next, and the third level has the fewest constraints. The fewer constraints, the easier it is to allocate. When assigning functions to groups at the same level, the group with the greatest constraints should be assigned first. Among them, redundant branches of a function group need to assign I / O signals to different I / O cards, which have the greatest constraints. Therefore, they are assigned first in the allocation process, followed by branches, then groups within the same group, and finally monitoring signals.

[0072] Assuming a controller node contains functional groups numbered 1, 2, and 3, during the initial calculation, by default, this site contains only one cabinet, and all three functional groups are assigned to that cabinet. If the allocation requirements are met, the allocation stops. If one cabinet cannot accommodate all points of the three functional groups, another cabinet is added. If two cabinets still do not meet the requirements, another cabinet is added, and so on, until the allocation requirements are met. The allocation results for each functional combination are compared, and the optimal I / O measurement point allocation result is automatically obtained with the goal of minimizing the number of cabinets and cards.

[0073] The automatic allocation method for I / O measurement points is explained further below:

[0074] Taking a portion of the measurement points in a nuclear power plant's nuclear heating system retrofit as an example, the list and codes of the measurement points are shown in Table 1. The project uses 8-channel AI (Analog Input) cards, 8-channel AO (Analog Output) cards, 16-channel DI (Digital Input) cards, 16-channel DO (Digital Output) cards, and 8-channel TC cards (configurable with TC (Thermcouple) or RTD (Resistance Temperature Detector) channels). The total number of card slots in each cabinet is 24, and the margin for cabinet card slots and card channels is set to 20%.

[0075] Table 1. List of I / O measuring points for a nuclear power plant's nuclear heating retrofit system.

[0076] If a DCS cabinet has four card slots (A / B / C / D), with 9 slots in each of columns A and D and 3 slots in each of columns B and C, then based on the I / O measurement points listed in Table 1, the allocation result is shown in Table 2. This requires 4 AI cards, 1 AO card, 2 DO cards, and 5 DI cards.

[0077] Table 2. I / O Measurement Point Allocation Results of a Nuclear Power Plant's Nuclear Heating Retrofit System

[0078] This application presents a multi-level coding rule for I / O allocation in a DCS system. By grouping functionally related I / O signals into a functional group, a multi-level coding method is designed for functional groups within a single site. For different functional groups that may be allocated to cards, an optimization objective of minimizing the number of cards is set, and an algorithm model for automatic I / O allocation is established. This realizes the automatic allocation of I / O measurement points, ensuring that the most economical measurement point allocation scheme is obtained while ensuring reasonable functionality, which greatly improves the quality and efficiency of project implementation.
