Description

Technical Field

[0001] The present invention belongs to the technical field of operation and maintenance of secondary equipment in power systems, and in particular relates to a design method and system for an embedded log system suitable for secondary equipment in power systems. Background Art

[0002] Secondary equipment in power systems typically utilizes embedded devices. Historically, due to limitations in chip and manufacturing costs and limited device resources, manufacturers focused on functional development, resulting in relatively simple systems. However, with the application of information technology in power systems, secondary equipment has become increasingly complex, with a trend toward integrating multiple devices into one. Not only are the functions of secondary equipment increasing in complexity, but the operating environment has also undergone significant changes. In particular, the widespread adoption of network technology in power grids has led to the emergence of extreme operating conditions such as network storms, situational awareness, and even cyberattacks. These new operating conditions pose significant challenges to device stability and troubleshooting.

[0003] Traditional logging system design techniques typically focus on recording exception branches during operation and recording core dump files when a program crashes. While traditional solutions can help troubleshoot program anomalies and correct errors, they often lack effective data support for reproducing and analyzing the root cause of the problem, especially when anomalies are caused by operating uncertainty due to network environment changes. Summary of the Invention

[0004] In order to address the deficiencies in the prior art, the present invention provides an embedded log system design method and system suitable for secondary equipment in power systems, so as to realize a full-process log system for equipment when secondary equipment is abnormal, and provide data support for problem tracing and positioning.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions.

[0006] The present invention first discloses a method for designing an embedded log system suitable for secondary equipment in a power system, the method comprising the following steps:

[0007] Step 1: Intercept the communication data between the power system secondary equipment and peripherals, save it to a network message file, set up a ring buffer between the peripheral interface and the application process to receive external drive data, and use shared memory to implement inter-process message communication;

[0008] Step 2: When the system detects an anomaly or an alarm, it backs up the intercepted network message files, the ring buffer, the log files and database during the task process, and the message data in the shared memory. When a core dump file is generated, it parses the core dump file and compresses the backup core dump file.

[0009] Step 3: Monitor system resource utilization. When utilization exceeds the set threshold, perform exception management on each process and compress the collected log files.

[0010] Step 4: Use a log analysis tool to parse and display the log file.

[0011] The present invention further includes the following preferred embodiments:

[0012] The network message file adopts the A\B backup mode, that is, when file A is full, file B is written; when file B is full, file A is cyclically overwritten.

[0013] The core dump file saves the memory and register data at the time the process crashes.

[0014] The method further comprises: parsing the core dump file when generating the core dump file, and compressing and backing up the core dump file.

[0015] It is detected whether a core dump file is generated. If it is generated, the core dump file is parsed, stack information and memory mapping information are exported, and the core dump file is compressed and backed up.

[0016] The system resource utilization includes CPU occupancy, memory usage or file handle utilization.

[0017] The abnormal management of each process further includes:

[0018] Record detailed information about resource usage by the abnormal process and then restart the process.

[0019] The displaying of the log file further includes:

[0020] Parse ring buffer data, display external driver data, display message interaction process according to preset message format, and display stack information and system resource monitoring information.

[0021] The present invention also discloses an embedded log system applicable to power system secondary equipment using the aforementioned embedded log system design method applicable to power system secondary equipment, comprising:

[0022] Initialization module, used to intercept the communication data between the power system secondary equipment and peripherals, save it to the network message file, set up a ring buffer between the peripheral interface and the application process to receive external drive data, and use shared memory to realize inter-process message communication;

[0023] The abnormality alarm backup module is used to back up the intercepted network message files when the system detects an abnormality or an alarm, and also back up the log files and database of the ring buffer during the task process and the message data in the shared memory. When a core dump file is generated, it is parsed and the core dump file is compressed and backed up.

[0024] The system resource monitoring module is used to monitor the utilization of system resources. When the utilization exceeds the set threshold, it performs exception management on each process and compresses the collected log files.

[0030] The beneficial effects of the present invention are that, compared with existing technologies, it provides an embedded logging system design method and system suitable for power system secondary equipment. This full-process logging system not only has all the recording functions of existing logging systems, but also provides snapshot storage of original network messages, process intermediate data, system resources, and other information generated by external interactions. It can not only record abnormal section data but also save data before the abnormality occurs, providing data support for abnormality reproduction and operating condition analysis.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] The embodiments described in this application are only part of the embodiments of the present invention, not all of the embodiments. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0041] To address the shortcomings of existing technologies, this paper focuses on the difficulty of troubleshooting equipment anomalies. It proposes a design method and system for an embedded, full-process logging system suitable for power system secondary equipment. The logging system covers network messages, application communication messages, inter-process interaction data, process runtime log files and database cross-sectional data, abnormal process stack information, and system resource logs. It also includes a log collection module and PC-side log analysis tools. This system can maximize the recording of various system data at the time of an anomaly, providing effective and comprehensive data support for post-anomaly analysis.

[0042] The present invention discloses an embedded log system design method applicable to power system secondary equipment, comprising the following steps:

[0043] Step 1: Intercept the communication data between the power system secondary equipment and peripherals, save it in a network message file, set up a ring buffer between the peripheral interface and the application process to receive external drive data, and use shared memory to implement inter-process message communication.

[0044] Specifically, in step 1, see Figure 1 Design and develop or use third-party packet capture tools to intercept communication data between secondary devices and peripherals. Network message files use the A\B backup method, that is, when file A is full, file B is written; when file B is full, file A is overwritten in a loop, and so on.

[0045] A ring buffer is added between the peripheral interface and the application (task process), and the buffer data is cleared and written by allocating space on demand when writing. Figure 2 This is a schematic diagram of peripheral communication message backup in the present invention.

[0046] Step 2: When the system detects an anomaly or an alarm, the intercepted network message files are backed up, and the ring buffer, the log files and database during the task process, and the message data in the shared memory are backed up. When a core dump file is generated, the core dump file is parsed and compressed to back up the core dump file.

[0047] See also Figure 3 When the system detects an anomaly or an alarm, the ring buffer is backed up. When the system detects an anomaly or an alarm, the two network message files A and B are backed up. Preferably, the network message file size is set to 1M by default. Figure 4 This is a schematic diagram of inter-process message buffer backup.

[0048] In addition, when the system detects an anomaly or an alarm, the log files and database files during the execution of the backup task process are backed up to prevent data in the log files and database from becoming invalid due to frequent log writing and refreshing.

[0049] like Figure 5 , enable the core file dump function to save the memory and register data when the process crashes. Detect whether a core dump file is generated. If so, parse the core dump file, export key information such as stack information and memory map, and compress and back up the core dump file.

[0050] Step 3: Monitor system resource utilization. When the utilization exceeds the set threshold, perform exception management on each process and compress the collected log files.

[0051] like Figure 6 As shown in the figure, a system resource monitoring module is designed to monitor system resources such as CPU occupancy, memory usage, and file handle utilization. When utilization exceeds a set threshold, the module records resource usage by each process and manages abnormal processes. After recording the detailed resource usage information of the abnormal process, the process is restarted.

[0052] like Figure 7 , design a log collection module to realize the log files generated above, and compress and package the collected log files.

[0053] Step 4: Use a log analysis tool to parse and display the log file.

[0054] like Figure 8As shown in the figure, a PC-based log analysis tool is designed to open and display collected log files. It supports network message file parsing and traffic analysis; parses ring buffer data and displays external driver data; displays log files and database files, and analyzes hotspot data; displays message interaction processes according to preset message formats, and displays stack information and system resource monitoring information.

[0055] The beneficial effects of the present invention are that, compared with existing technologies, it provides an embedded logging system design method and system suitable for power system secondary equipment. This full-process logging system not only has all the recording functions of existing logging systems, but also provides snapshot storage of original network messages, process intermediate data, system resources, and other information generated by external interactions. It can not only record abnormal section data but also save data before the abnormality occurs, providing data support for abnormality reproduction and operating condition analysis. This effectively improves the efficiency of problem location and root cause analysis.

The present invention also discloses an embedded logging system for power system secondary equipment based on the aforementioned embedded logging system design method for power system secondary equipment, comprising:

[0057] Initialization module, used to intercept the communication data between the power system secondary equipment and peripherals, save it to the network message file, set up a ring buffer between the peripheral interface and the application process to receive external drive data, and use shared memory to realize inter-process message communication;

[0058] The abnormality alarm backup module is used to back up the intercepted network message files when the system detects an abnormality or an alarm, and also back up the log files and database of the ring buffer during the task process and the message data in the shared memory. When a core dump file is generated, it is parsed and the core dump file is compressed and backed up.

[0059] The system resource monitoring module is used to monitor the utilization of system resources. When the utilization exceeds the set threshold, it performs exception management on each process and compresses the collected log files.
