Detailed Description
The scheme in the embodiments provided in the present application will be described below with reference to the drawings in the present application.
The terms "first," "second," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely descriptive of the various embodiments of the application and how objects of the same nature can be distinguished.
In order to facilitate understanding of the technical solutions of the present application, some technical terms related to the present application are described below.
Distributed Control Systems (DCS) are centralized and decentralized control systems that perform centralized monitoring, operation, management, and decentralized control of a production process based on a microprocessor. Nuclear DSC is an important plant in nuclear power plants. In the field of nuclear power, the operation and maintenance of a nuclear power DCS are very important works.
Generally, the automation degree of nuclear power DCS operation and maintenance is not high. The daily operation maintenance of the nuclear power DCS is mainly realized by manual regular inspection. In particular, the detection of hardware typically relies on manual inspection, periodic inspection, and manual measurement of various data, such as current, voltage, etc. And the routine maintenance of the software is to restart periodically, clean the disk space periodically and the like. When software breaks down, field personnel who patrol and examine and find the problem may not have the ability to solve, therefore need to send the data message of relevant trouble to the designer, through the artifical analysis location problem of designer, efficiency is lower.
The operation maintenance of the nuclear power DCS solves the abnormal problem, is low in efficiency and generally has hysteresis, and influences the normal work of the nuclear power DCS. In view of this, the present application provides a method for detecting an operation state of a distributed control system, where the method is applied to a processing device, and the processing device refers to a device with data processing capability, such as a server, and may also be a terminal device. Specifically, the processing device acquires the running parameter sequences acquired at different moments in a plurality of periods of the system, and acquires the running state trend of the system according to the running parameter sequences, so that the running state of the distributed control system can be detected according to the running state trend of the system, and the future running state of the system can be pre-judged, so that corresponding measures can be taken to avoid abnormal situations before the system is abnormal, and the normal work of the system is ensured. Next, a method for detecting an operation state of a distributed control system according to an embodiment of the present application will be described with reference to the drawings.
Referring to a flow chart of the method for detecting the operation state of the distributed control system shown in fig. 1, the method includes the following steps:
s102: the processing device obtains a sequence of operating parameters of the system.
The operation parameter sequence of the system comprises a plurality of operation parameters of the system, which are acquired in different periods at different moments.
The operating parameters of the system may include software and hardware parameters during operation of the system. For example, the hardware related parameters may include voltage, current, temperature, and the like. Software-related parameters may include system logs, application logs, infrastructure parameters, software performance parameters, and the like.
Specifically, the processing device may collect software and hardware parameters related to the operating state of the system to the secure intelligent gateway through a private network. As shown in fig. 2, the processing device collects hardware-related parameters such as voltage, current, temperature value, etc. to the L1 gateway through a message bus system (dbs), and then transmits the parameters to the secure intelligent gateway through the Gnet network. Similarly, the processing device collects software-related parameters, such as system logs, application logs, infrastructure parameters, software performance parameters, and the like, and transmits the parameters to the secure intelligent gateway through the Gnet network.
The system operation parameters sent to the safe intelligent gateway by the processing equipment can be an operation parameter sequence of the system, and the operation parameter sequence can be generated according to the operation parameters of the system collected at different moments in a plurality of periods and in a time sequence.
dbus is a mechanism for interprocess Communication, i.e., a low-overhead, low-latency IPC (Inter-Process Communication), and is adopted by various desktop environments (e.g., KDE, GNOME, etc.). dbus can provide multiple Message Bus to enable communication between applications.
gnet is an event-driven high-performance and lightweight network framework. gnet builds network applications directly using epoll and kqueue system calls instead of standard Golang network packages. The gnet is a high-performance, light-weight and non-blocking transport layer network framework realized by pure Go, and developers can use the gnet to realize an application layer network protocol, so that application layer network application is constructed.
As nuclear power has high safety, a safe intelligent gateway can be adopted as a gateway on the network edge side. The safety intelligent gateway can isolate the nuclear power DCS system and the intelligent operation and maintenance system, and realizes control of data flow in and out, so that data of the internal network nuclear power DCS system are protected from unauthorized external network access, and safety of the internal network nuclear power DCS system is guaranteed. Meanwhile, data sent outwards can be filtered through the safe intelligent gateway, data leakage is avoided, and safety of the nuclear power DCS is protected.
In some possible implementations, the collected system operating parameters or the operating parameter sequence generated according to the operating parameters may be stored in a unified data storage platform for storage, so as to perform subsequent processing, such as analyzing an operating state trend, checking a historical operating state, and the like.
The data storage platform may include various types of database systems to support the storage of various types of data, such as structured data, semi-structured data, and unstructured data. The data storage platform can store the operation parameters in the corresponding database according to the data types and the characteristics. For example, data representing the relationship is stored in a relational database, a sequence with obvious time characteristics is stored in a time sequence database, and text information such as a log is stored in a document type database.
The data storage platform is used for storing the operation parameter sequence and can also be used for storing other types of data. The platform provides a uniform access interface for the upper layer application so that the upper layer application can inquire and acquire data from the data storage platform.
Therefore, the processing equipment can realize automatic acquisition and storage of relevant parameters of the system and can ensure the safety of the nuclear power system.
S104: and the processing equipment acquires the running state trend of the system according to the running parameter sequence.
In general, the abnormal condition of the distributed control system occurs slowly, and there may be a small point, for example, an abnormal parameter occurs, but the abnormal parameter does not directly cause the system to be immediately abnormal, but after a period of time, the abnormal parameter has an increasingly large influence, and finally causes the abnormal operating state of the system.
In the process of converting the system from the normal operation state to the abnormal operation state, the condition that the system operation state is normal but the parameter in the system is abnormal may exist, but the system is not directly abnormal due to the abnormality. Therefore, the operation state trend of the system can be obtained by analyzing the operation parameter sequence of the system.
The processing equipment can analyze and acquire the running state trend of the system through various aspects according to the running parameter sequence.
Specifically, the processing device may obtain the performance trend of the software according to analysis on the logs in the running parameter sequence. And acquiring the running state trend of the hardware according to the running parameter sequence such as temperature, humidity and the like. Furthermore, the running state trend of the system and the like can be obtained through the incidence relation of various data.
Furthermore, an expansion algorithm can be customized according to the development requirements of the service, for example, trend changes of the electronic device are obtained through analysis of data such as current and voltage, aging trends of the device are obtained through data such as temperature and humidity, and other operation state trends of the system are obtained through comprehensive memory load, CPU load, network flow changes and other customized key indexes.
Through the description of the above content, the processing device can acquire the running state trend of the system through the analysis of the running parameter sequence, so that the problem can be found before the running state trend of the system is abnormal, and then the problem can be solved by adopting related measures.
The method comprises the steps of obtaining an operation parameter sequence of the system, wherein the operation parameter sequence comprises a plurality of operation parameters of the system, which are acquired periodically at different moments, and obtaining the operation state trend of the system according to the operation parameter sequence. Therefore, the operation trend of the system can be obtained according to the operation parameters of the system acquired by the distributed control system at different periods and different moments, and the advance detection of the operation state of the system is realized according to the operation trend of the system.
In some possible implementations, the present embodiment further includes the following steps:
s106: and when the running state trend of the system is abnormal, the processing equipment generates corresponding processing measures aiming at the running trend.
When the abnormal operation trend of the system is detected, the processing device can analyze the reason of the abnormal operation trend in various ways, such as extracting keywords of the log and analyzing the reason of the software fault by text.
When the reason of the operation trend is determined, the processing equipment determines a corresponding processing measure aiming at the reason.
The corresponding processing measures may be preset, for example, the system state may be tested in advance to obtain abnormal situations that may occur, then a plurality of abnormal situations and corresponding processing measures are preset, and when the operation trend may be the abnormal situation, the corresponding processing measures are executed in advance to convert the operation trend into a normal state before a problem occurs.
Alternatively, a historical processing measure may be obtained, and the historical processing measure may be a corresponding processing measure in which the same abnormal condition occurs in the historical operating condition of the system. When the historical measures have a good effect in the historical operating condition, the historical measures can be continuously called when problems occur in the follow-up process.
Further, a possible operation trend does not appear in the preliminary test or the historical operation, and the system can analyze the operation state trend, acquire corresponding measures under the similar operation state trend and process the measures.
In some possible implementation manners, the system may also send the abnormal situation corresponding to the running state trend to a developer, and prompt the developer to process the abnormal situation.
The system may send the operating state trend to the developer in a variety of ways, for example, the operating state trend may be displayed on a display interface of the distributed control system. In order to further show the operation state trend, the operation state trend can be presented in the forms of pictures, tables, videos and the like, wherein the display interface of the system can be various terminal interfaces such as a projection, a mobile phone, a computer and the like.
In other possible implementation manners, the processing device may also display the processing measures obtained by the system through historical data, preset relationships, and the like according to the operation trend to the developer, so that the developer can select the processing measures.
Further, the process device displays an interface to the developer, which may include corresponding processing measures, may also include analyzing the obtained system operation state trend, and may also include an operation parameter sequence of the system. The display interface can display data analysis of the operation parameter sequence of the system, the analyzed operation state trend and the probability of the appearance of different operation state trends, so that a developer can select the operation parameter sequence according to the display page. The content of the display page can be set by a user in a self-defined way, for example, the change trend of the system operation state can be displayed in the form of a line graph under the condition that the change trend of the data needs to be displayed, and the scale condition can be displayed in the form of a sector graph under the condition that the scale of the data needs to be displayed.
In summary, the embodiment provides a method for detecting an operation state of a distributed control system, which obtains an operation state trend of the system by obtaining an operation state parameter sequence including a plurality of operation parameters of the system acquired at different periods and different times. Therefore, the operation trend of the system can be analyzed and obtained according to the operation parameters of the system, collected by the distributed control system at different periods and different moments, and then the advance detection of the operation state of the system is realized according to the operation trend of the system.
Furthermore, when the running state trend of the system is abnormal, corresponding processing measures can be generated according to the running trend, so that possible problems can be solved before the system runs abnormally, namely according to the corresponding processing measures, the abnormal condition of the system is avoided, and the safe and stable running of the system is ensured.
