Description

Technical Field

[0001] This invention relates to the field of simulator operation technology for 3KeyMaster simulation platform and DCS platform, and more specifically, to a method for rapid IC upgrade of simulator. Background Technology

[0002] When simulators based on the 3KeyMaster simulation platform and DCS (Digital Instrumentation and Control System) platform perform on-site unit consistency upgrades, such as after modifying input / output boards, it is necessary to regenerate the OGD communication files between the 3KeyMaster platform and the DCS on the 3KeyMaster platform. Although the ICs on the DCS can be upgraded using the DCS IC upgrade tool, there is no such tool for upgrading the ICs (operating conditions) on the 3KeyMaster platform. Therefore, after the simulator directly calls the relevant ICs to run, many parameters will fluctuate greatly, and many alarms will occur. Some ICs are in more serious condition, causing the machine to trip or the stack to fail after being called and run, so the original ICs can no longer be used directly. If the IC condition is poor after upgrading the OGD file, it requires manual establishment of standard operating conditions. Completing this task would take three weeks with two experienced senior staff working in shifts each day. If the IC condition is slightly better after upgrading the OGD file, meaning that the existing ICs can be used to build new ICs, many alarms will generally occur during the process of using these ICs. In one test simulator, there were about fifty or sixty alarms or more. The total time to clear the alarms is also very long, and many parameters fluctuate greatly. It takes a long time for the IC to stabilize. This situation takes slightly less time than rebuilding the IC, but the total time for stable operation under standard operating conditions will still be more than two weeks. In both of these scenarios, due to the OGD regeneration, many states will change. Stabilizing or rebuilding the IC involves manual inspection and verification. Because the simulator system has many screens and many controls, the states of valves, controls, etc., cannot guarantee or continue the initial state of the previously good IC. If the previous IC had initial state deviations and these were corrected, the results cannot be continued. Both methods have drawbacks; they cannot guarantee the comprehensiveness and correctness of the IC continuing the initial state of the previous good IC. Therefore, the previous IC cannot be used directly, and the relevant IC needs to be rebuilt. Summary of the Invention

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0045] Figure 1 This is a flowchart illustrating the rapid IC upgrade method for an analog machine provided in an embodiment of the present invention;

[0046] Figure 2 This is a schematic diagram of the OGD file content provided by the present invention;

[0047] Figure 3 This is a schematic diagram of the IC file content on the DCS side provided by the present invention. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention provides a rapid IC upgrade method for simulators. This method can directly and quickly stabilize the IC based on the original IC file, and can rapidly clear alarms, thereby quickly establishing a standard IC file. After the IC file is loaded and run according to the method, the parameters do not fluctuate significantly, and alarms are very few. The workload of manually adjusting parameters is greatly reduced, allowing for rapid alarm clearing and achieving the goal of rapid IC file upgrade. This method can save significant manpower and resources. The status of equipment, valves, and control valves is ensured and maintained as the original good IC initial state, preserving and continuing any deviations from the previous IC initial state, thus ensuring the comprehensiveness and correctness of maintaining the original good IC initial state.

[0050] Specifically, such as Figure 1 As shown, in a preferred embodiment, the rapid IC upgrade method for the simulator includes the following steps:

[0051] Step S101: Generate an importable IC file.

[0052] Among them, the IC file is the system operating condition file. IC refers to system operating conditions.

[0053] In some embodiments, generating an importable IC file includes: loading data; the data includes: operating conditions or operating conditions and process tasks; exporting the IC file on the DCS side; reading the contents of the OGD file and the contents of the IC file on the DCS side; and generating an importable IC file based on the contents of the OGD file and the contents of the IC file on the DCS side.

[0054] Optionally, in this embodiment of the invention, the OGD file content includes: point names and dimensions, specifically as follows: Figure 2 As shown. The IC file on the DCS side includes: dimensional variables and values, specifically as follows: Figure 3 As shown.

[0055] In some embodiments, generating an importable IC file based on the OGD file content and the IC file content on the DCS side includes: determining the dimension variable and dimension corresponding to the point name based on the point name; searching for the dimension variable and value corresponding to the determined dimension variable in the IC file content on the DCS side according to the determined dimension variable; obtaining the correspondence between the point name, dimension variable and value according to the point name, the dimension variable and value corresponding to the determined dimension variable; and generating an importable IC file according to the correspondence between the point name, dimension variable and value.

[0056] Specifically, before updating the newly generated OGD file (i.e., the communication file between the 3KeyMaster simulation platform and the DCS platform, with the .OGD extension), the 3KeyMaster simulation platform first loads data (i.e., loads operating conditions, or loads operating conditions and process tasks (TASK)). It then exports the IC file from the DCS side by right-clicking the OGD icon on the DCS side. Next, it reads the contents of the OGD file and the exported IC file from the DCS side. Then, it matches each point name in the OGD file content with its corresponding dimension variable and dimension. Finally, it finds the corresponding values ​​in the exported IC file from the DCS side using the corresponding dimension variable and dimension, thus determining the correspondence between point names, dimension variables, and values. Finally, it generates an importable IC file using a statement format of point name + equal sign + value + semicolon. The importable IC file is an IC file with the .TIC extension. It should be noted that the 3KeyMaster simulation platform referred to in this invention is a platform that can simulate process systems (such as pipelines, valves, equipment, etc.), simulate DCS logic, and simulate interfaces.

[0057] Because the OGD file format is a one-to-one correspondence between a point name and an array dimension, but not always consecutive, the total number of lines is very large, sometimes exceeding tens of thousands. In contrast, the exported IC file is a continuous pair of array variables and their corresponding values, presented in multi-line format, also with a very large number of lines. Manually comparing and searching one by one would be extremely labor-intensive, time-consuming, error-prone, and could not guarantee accuracy. By determining the correspondence between point names, dimension variables, and values ​​to generate an importable IC file, efficiency can be significantly improved, and human error can be reduced.

[0058] Step S102: Upgrade the IC file to be upgraded on the DCS side to obtain the IC upgrade file on the DCS side.

[0059] In some embodiments, upgrading the IC file to be upgraded on the DCS side to obtain the IC upgrade file on the DCS side includes: determining the IC file to be upgraded; upgrading the IC file to be upgraded on the DCS side to obtain an initial IC file; detecting whether there is a damaged IC file in the initial IC file; if so, correcting the damaged IC file; and obtaining the IC upgrade file after completing the correction.

[0060] The process of correcting a corrupted IC file includes: determining the original IC files of each control station related to the operating conditions in the corrupted IC file; obtaining any upgraded IC file; renaming the upgraded IC file to the same filename as the corrupted IC file; and updating the original IC file data to the IC file according to the method of each control station.

[0061] Specifically, the DCS platform uses the HOLLiAS-N system, which utilizes its built-in IC tool. Based on user input (such as selection), all IC files requiring upgrades can be identified. The DCS platform then directly upgrades these IC files to obtain initial IC files. Next, the initial IC files are inspected to identify corrupted IC files (those with corrupted operating conditions). After identifying corrupted IC files, the original IC files for each control station related to the operating conditions within the corrupted IC file are exported based on the corrupted IC filename. Then, any healthy and upgraded IC file is copied, and its filename is renamed to match the corrupted IC file. After renaming, batch modifications can be performed on each control station to generate replaceable IC files, completing the IC file upgrade on the DCS side.

[0062] It should be noted that the original IC file is an old, unupgraded IC file.

[0063] Step S103: Load the importable IC file and the IC upgrade file on the DCS side.

[0064] In some embodiments, loading the importable IC file and the DCS-side IC upgrade file includes: loading the importable IC file and the DCS-side IC upgrade file; determining the values ​​in the importable IC file and the DCS-side IC upgrade file that do not need to be changed; and loading the values ​​that do not need to be changed into the importable IC file.

[0065] Step S104: Perform a combined operation on the importable IC file and the IC upgrade file on the DCS side.

[0066] In some embodiments, the combined operation of the importable IC file and the IC upgrade file on the DCS side includes: after loading the importable IC file and the IC upgrade file on the DCS side, controlling the application to be applied to be in a mounted state; starting the system to run for a preset time period; stopping the system after running for the preset time period; modifying the state of the application to be applied to run the application to be applied; and starting the system to run.

[0067] Step S105: Clear the alarm and verify the status. After clearing the alarm and verifying the status, save all running IC files.

[0068] Furthermore, during system operation, alarms are obtained by logging out or restarting the computing server in the DCS system.

[0069] Specifically, first, after the simulator is prepared, it identifies (i.e., locates) the values ​​that do not need to change in the operating condition (these values ​​are restored before saving the IC, allowing the data to change), such as the xenon poisoning parameter values. These are then loaded into an importable IC file, ensuring that the values ​​of the relevant data points from the old OGD file are loaded into the simulator. Next, on the 3KeyMaster simulation platform, the application to be used (e.g., DCS.exe) connected to the DCS is mounted by double-clicking (ensuring the DCS platform is not running). Then, on the 3KeyMaster simulation platform, the system runs for a preset time period (e.g., 5 seconds) to ensure the correctness of the interface variables between the 3KeyMaster and DCS platforms. The simulator is then frozen, stopping the system. Next, on the 3KeyMaster simulation platform, DCS.exe is changed from mounted to running by double-clicking. Finally, the entire simulator platform is run. Additionally, during operation, alarms are cleared and the status is verified. After clearing alarms and verifying the status, all running IC files are saved.

[0070] Using this method, the values ​​generated in the importable IC file can be loaded correctly, completely, and accurately into the simulator. After operation, the parameters remain relatively stable without significant fluctuations, and the status of equipment, valves, and control valves does not exhibit abnormal changes. Testing revealed that many devices no longer require manual intervention. For example, the APG system (nuclear power plant steam generator blowdown system) no longer needs to be put into operation. In systems like ARE (nuclear power plant main feedwater system) and APA (nuclear power plant electric main feedwater pump system), parameters such as water level and flow rate will not fluctuate significantly. Furthermore, the status of some valves and equipment in systems like AHP (nuclear power plant high-pressure feedwater heater system) and CEX (nuclear power plant condensate system) will not change abnormally and does not require manual adjustment. Therefore, adjusting or regulating the status of controls is no longer necessary; only alarm clearing and alarm stabilization are required.

[0071] Furthermore, to expedite the presentation of IC alarms and other alarms, the DCS platform's computing server can be logged out or restarted during combined operations. Logging out typically requires only one operation, although in some cases two are necessary: ​​re-running the computing server process, clearing the alarm, fixing the alarm location (no flashing), verifying the status, and saving the IC, thus completing an IC upgrade. Testing shows that an IC upgrade typically takes about 10 minutes, with the shortest time being only about 4 minutes.

[0072] By using the IC rapid upgrade method of the simulator of this invention, each IC can be upgraded and saved individually. This method is both efficient and accurate, and it can continue and retain the results of previous IC deviations and the display status of valves, pumps, controls, etc. Furthermore, compared to the previous method of restoring or re-establishing standard IC operation, which took two to three weeks or more, this method can complete the standard IC establishment work in about three days. The entire operation is also much easier, with significantly improved efficiency and accuracy. Unlike re-establishing ICs, which is time-consuming and labor-intensive, this method eliminates the need for highly experienced personnel to establish operating conditions, greatly reducing manpower and workload. This allows personnel without extensive experience to perform the work, thus saving labor costs. The total cost calculation, assuming a cost of 200 yuan / hour for a senior operator, with two people working in two shifts for three weeks (2 people * 8 hours * 2 shifts * 5 days * 3 weeks = 480 hours), is 96,000 yuan. If we consider personnel in high-level positions who do not require extensive experience, the cost per hour is 100 yuan. The total work time would be 2 people * 8 hours * 3 days = 48 hours, resulting in a cost of 4800 yuan. Therefore, the labor cost savings could reach over 90,000 yuan. Furthermore, in a certain nuclear power plant, at least one simulator needs upgrading annually, sometimes two or even three simultaneously. Based on the number of times three simulators are upgraded at the same time, the labor cost savings could reach up to 90,000 yuan * 3 = 270,000 yuan. This demonstrates that this upgrade method is efficient, accurate, and significantly reduces labor costs. Moreover, it saves labor costs annually for any simulator upgrade involving OGD adjustments, making the savings substantial. In addition, this method is pioneering; other bases and power plants involving IC upgrades related to OGD adjustments on the 3KeyMaster simulation platform can adopt this method for IC re-upgrades and reconstruction.

[0073] Compared to nuclear power plants, this simulator's rapid IC upgrade method efficiently and quickly establishes the IC, improving the efficiency of consistency modification between the simulator and the actual unit, enhancing the quality of simulator upgrades, and contributing to improved simulator training quality. The status of equipment, valves, and control valves is ensured and maintained from the previous good initial IC state, preserving and continuing any deviations from the previous initial IC state, ensuring the comprehensiveness and correctness of maintaining the previous good initial IC state. This method features a Windows system, a green, installation-free mode, and the ability to be used immediately after copying. It reduces human error and workload, significantly lowering labor costs, saving at least 90,000 yuan and up to 270,000 yuan annually. This invention is applicable to IC upgrades involving OGD adjustments related to the 3KeyMaster simulation platform. It applies not only to the 3KeyMaster simulation platform but also to platforms derived from it. It is applicable not only to partial upgrades of DCS systems but also to full upgrades of DCS systems, and has broad application prospects. It can be promoted and applied to other bases within the group and outside the group. This method can be used to rebuild ICs, reduce human error, reduce workload, greatly reduce labor costs, and quickly and efficiently complete the stable rebuilding of ICs, improving the accuracy and comprehensiveness of ICs.
