[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and which provides a joint debugging method for a ladder computer monitoring system, comprising the following steps:

[0034] S1: Test environment construction and network configuration.

[0035] Specifically, the following steps are included: building a virtualization platform to simulate the substation host environment; configuring network connections, including the connection between the substation communication server and the main station center offline communication server; implementing network security measures, such as configuring firewall rules and deploying intrusion detection systems; using network analysis tools to monitor data flows to ensure normal communication; and developing automated scripts to regularly check the system connection status and report anomalies.

[0036] Furthermore, five communication links are configured, including four fiber optic channels and one satellite public network security access area, which is an expansion of the original support for up to four channels.

[0037] S2: After the network configuration is complete, synchronize the database to make the database in the test environment consistent with the main database.

[0038] Preferably, the method comprises the following steps:

[0039] After the communication link is established, the master station will first check the database. After the verification is correct, the master station will first call the point table. The substation will send the point table according to the category (telesignaling, telemetering, remote control, teleadjustment, telepulse, curve). The master station will automatically compare and match the measurement point descriptions called up. For non-conventional description points that cannot be matched automatically, a manual matching interface is provided to synchronize the substation table description and keywords to the master station database; execute a general database call to ensure that the data on the substation side and the master side are consistent; implement a real-time point table synchronization mechanism to ensure that the point tables on both sides are continuously consistent.

[0040] Specifically, the 104 master station no longer needs to establish a point table. After the 104 communication link is established, the master station will first call the point table, and the substation side will upload the point table once according to the telesignaling, telemetering, remote control, remote adjustment, remote pulse, and curve categories. Only after judging that the point table has been uploaded completely, the master station sends a general call message, and then interacts according to the conventional 104 protocol process. During the first communication, the master station will automatically compare and match the called measurement points according to the description; after the matching is completed, the synchronization measurement point and synchronization keyword operations are completed according to the needs.

[0041] Synchronous measuring point means that the called sub-station table description needs to be synchronized to the measuring point description in the master station database. Synchronous keyword means that the measuring point keyword sent by the sub-station needs to be synchronized to the measuring point table keyword in the master station database to achieve a one-to-one mapping between the measuring points of the master station and the measuring points of the sub-station.

[0042] Furthermore, the master station automatically compares and matches the following contents according to the called measurement point description:

[0043] Analyze and number the database structure of the master station and the substation to generate a database structure description set, recorded as DB Si ={T1,T2,...,Tn}, where DB Si Represents a set of structural descriptions of any database, i represents the database number, n represents the table structure number, and Tn represents the nth table structure;

[0044] Perform field analysis on each table structure Tn and generate a field description set, recorded as FD n ={F1,F2,...,Fm}, where FD nRepresents a set of field descriptions of any table structure, n represents the table structure number, m represents the field number, and Fm represents the mth field;

[0045] Generate a set of modification instructions based on the database description document provided by the master station, denoted as MC k ={M1,M2,...,Mp}, where MC k represents the modification instruction set of the k-th database, p represents the modification instruction number, and Mp represents the p-th modification instruction;

[0046] Each modification instruction Mp is parsed to generate an operation feature description, which is expressed as: Op→AFp:(A,B,C,D), where Op represents the operation type (such as add, delete, modify) corresponding to the pth modification instruction, AFp represents the operation feature of the pth modification instruction, and A, B, C, and D represent the affected database, table, field, and new value, respectively;

[0047] According to the operation feature description, generate a set of automated execution scripts, denoted as AE Si ={S1,S2,...,Sq}, where AE Si represents the set of automated execution scripts for the i-th database, q represents the script number, and Sq represents the q-th execution script.

[0048] Furthermore, a database general call is performed to ensure that the substation and master station data are consistent, including the following:

[0049] Define the database total call operation set, denoted as DT Ri ={R1,R2,...,Rr}, where DT Ri represents the total call operation set for the i-th database, r represents the total call operation number, and Rr represents the r-th total call operation;

[0050] Parameterize each general call operation Rr to generate a general call configuration description, expressed as: Cr→PCr:(a,b,c,d), where Cr represents the configuration of the rth general call operation, PCr represents the parameter characteristics of the configuration, and a, b, c, d represent the general call range, time interval, number of concurrent calls, and timeout settings, respectively;

[0051] Execute the general call operation and record the data transmission characteristics, which are expressed as: Tr→DTr:(e,f,g,h), where Tr represents the execution timestamp of the rth general call operation, and DTr represents the data transmission characteristics of this general call. e, f, g, h represent the amount of transmitted data, transmission rate, error rate and completion degree, respectively.

[0052] Analyze the results of the general call and generate a consistency evaluation matrix, which is recorded as:

[0053] CMij = {V 11 ,V 12 ,...,V uv}

[0054] Among them, CM ij represents the data consistency evaluation matrix of the slave station side (i) and the master station side (j), u and v represent the row and column respectively, V uv Represents the consistency evaluation value of the uth row and vth column.

[0055] According to the consistency evaluation matrix, the formula for calculating the overall consistency index CI is:

[0056] CI=ω1.X+ω2.Y+ω3.Z

[0057] Among them, ω1, ω2 and ω3 are the weights of the complete consistency rate, partial consistency rate and inconsistency rate respectively; X represents the complete consistency rate, Y represents the partial consistency rate, and Z represents the inconsistency rate.

[0058] If the consistency index CI does not meet the standard, manual verification will be performed.

[0059] S3: Check the uplink signals of each device one by one to ensure the accuracy and consistency of signal transmission; conduct remote control tests to verify that remote control commands can be accurately issued and correctly executed to ensure the normal control function of the system.

[0060] Conduct "back-to-back" simulated joint debugging tests, establish a communication network, and perform partial verification, including uplink signal verification, image verification, and downlink verification.

[0061] Preferably, develop sub-site table processing rules, remove non-standard characters (such as line breaks), create database measurement points for AGVC advanced operation points, and upload them uniformly; optimize sub-site table descriptions to avoid matching errors caused by repeated descriptions.

[0062] Implement load balancing strategies for point-to-table calling and total calling to avoid network load problems when 9 stations communicate simultaneously.

[0063] It also includes using scripts on the virtual host on the substation side to batch force the analog quantity, temperature quantity, switch quantity and SOE quantity on the power plant side, where the telemetry signal is forced by increasing or decreasing the measured value, and the telesignal signal is forced by 1, 0 cycle and then 0, 1 cycle. After each force is completed, the manufacturer of Nanzi will export the communication point table and real-time measured values ​​on the communication machine on the power plant side, and export the communication point table and real-time measured values ​​on the communication machine on the main station side, perform automated testing on various signals, automatically generate test cases based on signal characteristics, export and compare the communication point table and real-time measured values ​​on the substation side and the main station side; develop a visual monitoring interface to display the forced status and results in real time, force the control quantities one by one, verify the command issuance and alarm return, implement command execution performance analysis, and optimize the efficiency of command issuance.

[0064] Preferably, automatically generating a test case according to the signal characteristics comprises the following steps:

[0065] Collect all signal types that need to be tested, define the signal type set ST = {analog quantity, switch quantity, calculation quantity, ...}; for each signal type s∈ST, define the attribute set AP(s) = {range, accuracy, rate of change}; create a signal characteristic database SDB = {(s,AP(s))|s∈ST}.

[0066] Based on the signal characteristic database SDB, define the normal operation scenario set NOS = {nos1, nos2, ..., nosn}; for each nosi∈NOS, define the signal set involved Generate an abnormal scene set AOS = {aos|aos = F(nos), nos∈NOS}, where F is the abnormal generation function; define the scene relationship graph SRG = (NOS∪AOS, E), where E represents the conversion relationship between scenes.

[0067] It should be noted that the anomaly generation function F uses the perturbation method to generate anomaly scenarios:

[0068] F=nos+∈

[0069] Among them, nos is the normal scene and ∈ is the random noise vector.

[0070] For each signal type s∈ST, define the basic test rule set BTR(s) = {range test, accuracy test, rate of change test}; based on the scene relationship graph SRG, define the combined test rule set CTR = {ctr1,ctr2,...,ctrm}; for each ctri∈CTR, define ctri = g(Si,Gi), where Gi is a regular function.

[0071] Furthermore, the formula of Gi is:

[0072] Gi(si)=hi*si

[0073] Where hi is the impulse response of the filter and * represents the convolution operation.

[0074] The combination function g is used to combine the subset Si and the rule function Gi into a combined test rule, which can be simply defined as a tuple.

[0075] Define the time series T = {t1, t2, ..., tk}, for each scenario sc∈(NOS∪AOS), generate the signal change function set SVF(sc) = {svf|svf:S(sc)×T→G}; construct the dynamic test sequence DTS = {(sc, SVF(sc), TR(sc))|sc∈(NOS∪AOS)}, where,

[0076] For each dts∈DTS, generate a test case set TC(dts)={tc1,tc2,...,tcl}; define a test execution function EXEC(tc)→{PASS,FAIL}; for each tc∈TC(dts), execute EXEC(tc) and record the result.

[0077] Calculate test coverage:

[0078]

[0079] Among them, ωi is the weight of the coverage rate in the i-th one; f is a smoothing function to deal with the fluctuation of coverage rate; ω(s) represents the importance of each signal s; n 0 is the coverage type; e is the indicator function, which is 1 when s is tested and 0 otherwise.

[0080] Identify the failed test case set FTC = {tc|EXEC(tc) = FAIL}, and based on the failed test case set FTC, update the anomaly generation function F and the combined test rule generation function g; if COV<threshold or |FTC|>0, return to the signal characteristic database SDB, redefine the normal operation scenario set, and perform iterative optimization again.

[0081] Furthermore, the communication point table is exported from the substation side and the main station side respectively, the real-time measurement data on both sides are obtained, the point table mapping function is created, and the consistency index is calculated. If the consistency index is < the preset consistency threshold, the point table synchronization process is triggered, otherwise, the point table synchronization process is not triggered, and it is confirmed that the system data consistency meets the expected standard.

[0082] Furthermore, the control quantities are enforced one by one, and the verification command is issued and the alarm is returned, including:

[0083] Specifically, list all controllable quantities in the system, such as switch quantities, analog quantities, etc., and determine the normal working range and limit values ​​of each control quantity; formulate a test plan, including the mandatory value and expected response of each control quantity, ensure the safety of the test environment, and conduct risk assessment when necessary.

[0084] Perform forced operations on each control quantity in turn according to the plan. The forced values ​​should include values ​​within the normal range and limit values ​​beyond the normal range; observe whether the system correctly receives and executes each forced command, record the response time and execution status of the command, monitor whether the system generates corresponding alarms for abnormal forced values, and check the accuracy, timeliness and completeness of the alarm information

[0085] Record the process, results and observed anomalies of each test in detail, analyze the data, and identify potential system defects or improvement points.

[0086] An optional, intuitively designed user interface displays key information and updates the mandatory status of each signal in real time.

[0087] S4: Check the screen to ensure that the various graphic interfaces in the monitoring system can accurately reflect the device status and signal changes, and test the signal shielding function to ensure that when shielding certain signals, the system can process and shield these signals normally to avoid false alarms and misoperation.

[0088] Screen verification includes verification of switch quantities and verification of analog quantities.

[0089] Preferably, the positions of switches, unit status, etc. displayed on the screens of the communication machine on the master station side and the communication machine on the slave station side are compared to see whether they are consistent, and whether the temperature and analog quantity displays are consistent.

[0090] When the signal quality is forced to "bad", the screen display is correct. After the detection is correct, a screenshot is saved.

[0091] Start the signal shielding function on the slave server screen, force the signal point on the virtual host, check whether the point in the slave communication machine database is synchronized, and check whether the point on the master communication machine maintains the original value.

[0092] After checking that everything is correct, exit the signal shielding function and check whether the point on the master station side communication machine is updated.

[0093] S5: After all tests are completed, the system is restored to its initial state and a test report is generated.

[0094] After the uplink signal, picture and downlink signal are checked, the error information is modified and checked; the checking process also includes operations such as sound and light alarms when major problems occur. After confirmation, internal and external communications are carried out.

[0095] Use the in-plant communication machine as the host, restore the original configuration based on the modification record, develop configuration snapshot and recovery tools, and support multiple recovery points.

[0096] Gather all test results and create comprehensive reports using the intelligent reporting system.

[0097] Implement a test result visualization platform that provides interactive data exploration capabilities, hold summary meetings to discuss issues and improvement points during the testing process, implement continuous improvement processes, and regularly evaluate and optimize debugging methods.

[0098] After the test, remote open-loop debugging is carried out with the power grid, and the communication channel is checked to ensure that there are no problems with the remote closed-loop. Then, the remote closed-loop operation test is carried out, and the equipment is debugged offline.

[0099] This embodiment also provides a joint debugging method system of a ladder computer monitoring system, including:

[0100] The network configuration module is used to build a test environment and configure the network; the database synchronization module is used to synchronize the database after the network configuration is completed, so that the database in the test environment is consistent with the main database; the signal verification and remote control test module is used to verify the uplink signal of each device one by one, and perform remote control tests to verify whether the remote control instructions can be accurately issued and correctly executed; the screen verification and signal shielding test module is used to perform screen verification to ensure that various graphical interfaces in the monitoring system can accurately reflect the device status and signal changes, and test the signal shielding function; the report generation module is used to restore the system to the initial state after all tests are completed, and generate a test report.

[0105] Example 2

[0106] Referring to Table 1, which is the second embodiment of the present invention, in order to further verify the beneficial effects of the present invention, experimental data of the joint debugging method of the ladder computer monitoring system are provided.

[0107] In order to verify the effectiveness of a joint debugging method for ladder computer monitoring system, a systematic experiment was carried out.

[0108] The experimental steps include setting up the test environment and network configuration, database synchronization, checking the uplink signals of the devices one by one, checking the screen, restoring the system to the initial state and generating a test report.

[0109] Before the experiment started, a virtualization platform was first built to simulate the substation host environment. The platform was built using VMware ESXi, and multiple virtual machines were configured to simulate the substation communication server and the main station center offline communication server.

[0110] To ensure the security and reliability of data communication, firewall rules were configured, an intrusion detection system (IDS) was deployed, and Wireshark was used to monitor network traffic. To ensure normal communication, an automated script was developed to regularly check the system connection status and report anomalies.

[0111] After the network configuration was completed, the database was synchronized.

[0112] According to the database description provided by the substation, the point table on the substation side and the main station side is modified using an automated tool: First, the database structure is analyzed and numbered to generate a database structure description set DBSi, and then the fields of each table structure Tn are analyzed to generate a field description set FDn; according to the database description document provided by the substation, a modification instruction set MCk is generated, and each modification instruction Mp is parsed to generate an operation feature description. Based on these operation features, an automated execution script set AESi is generated.

[0113] When executing the database general call operation, the database general call operation set DTRi is defined, and each general call operation Rr is parameterized. The general call operation is executed and the data transmission characteristics are recorded. The consistency evaluation matrix is ​​generated by analyzing the general call results, and the overall consistency index CI is calculated.

[0114] The uplink signals of each device were checked one by one: all signal types that needed to be tested were automatically tested, test cases were automatically generated according to the signal characteristics, and the communication point table and real-time measurement values ​​on the substation side and the main station side were exported and compared; a visual monitoring interface was developed to display the forced status and results in real time, and the control quantities were forced one by one to verify the accuracy of command issuance and alarm return.

[0115] Subsequently, a screen check is performed to ensure that the various graphic interfaces in the monitoring system can accurately reflect the equipment status and signal changes. When the signal quality is forced to "bad", the correctness of the screen display is checked and a screenshot is taken and saved. The signal shielding function is started on the substation server screen, and a signal point is forced on the virtual host. Check whether the point in the substation communication machine database is synchronized, and at the same time check whether the point on the main station side communication machine maintains the original value.

[0116] Finally, the system was restored to its initial state and a test report was generated. The factory communication machine was used as the host to restore the original configuration according to the modification record. Multiple recovery points were supported, all test results were summarized, and a comprehensive report was created using the intelligent report generation system. Some of the experimental data of this experiment are as follows:

[0120] It can be seen from the experimental data that the method of the present invention shows significant advantages in many aspects: for example, during the construction of the virtualization platform and the network configuration stage, the network delay and packet loss rate were maintained between 5-7ms and 0.2%-0.3%, respectively, ensuring low latency and high reliability of communication. This result verifies the effectiveness of using firewall rules and intrusion detection systems, ensuring the security and stability of the test environment.

[0121] In addition, during the database synchronization phase, the data synchronization time is 50-60 seconds, the uplink signal accuracy after database synchronization reaches 99.7%-99.9%, and the remote control command response time is maintained between 150-160ms. Compared with the common synchronization time of more than 100 seconds and 98% signal accuracy in the prior art, the method of the present invention significantly improves synchronization efficiency and data accuracy.

[0122] The use of automated execution scripts and parameterized settings for database call operations ensure real-time synchronization and consistency of data, significantly reducing the complexity and error rate of manual operations.

[0123] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
