Description

Technical Field

[0001] The invention belongs to the field of trusted DCS controllers, and in particular relates to a message sending method and equipment for trusted DCS real-time control software of a power plant. Background Art

[0002] The commonly used trusted (Distributed Control System) real-time control software system in power plants has the characteristics of decentralized control by multiple real-time trusted terminals and centralized management by a trusted management center, so as to realize real-time monitoring and optimization control of the power generation process. Specifically, on the one hand, the DCS system adopts a decentralized control method to distribute the various systems, processes and equipment of the power plant to several control stations. These control stations are relatively independent and complete control tasks within their respective responsibilities. This design reduces the risk of single point failure and improves the reliability and stability of the system. The real-time trusted terminal can collect field data in real time, including key parameters such as temperature, pressure, and flow, and transmit these data to the trusted management center in real time through the communication network. At the same time, these terminals can also receive instructions from the management center, adjust control parameters in real time, and realize precise control of the power generation process. Each real-time trusted terminal has a high degree of credibility, and the security of data transmission and instruction execution is ensured through built-in security mechanisms and authentication methods. In addition, the system also has fault detection and self-recovery capabilities, and can automatically switch to backup equipment or take other measures in the event of a fault to ensure the continuous operation of the system. On the other hand, the trusted management center is the core part of the DCS system. It is responsible for receiving data and status information from various real-time trusted terminals, and centrally processing and displaying them. Operators and administrators can view the status, parameters and alarm information of the power generation process in real time through the human-machine interface (HMI), and realize comprehensive monitoring of the entire power plant. The management center also has the optimization control function, which can automatically adjust the control strategy and optimization parameters according to the needs and actual conditions of the power generation process. Through advanced control algorithms and model prediction technology, the optimized operation of the power generation process is realized, and the power generation efficiency and economic benefits are improved. The management center is also responsible for the security management of the system, including user authority management, data encryption transmission, firewall settings, etc. It ensures that only authorized users can access system data and control functions to prevent unauthorized access and malicious attacks.

[0003] Each trusted DCS real-time control terminal needs to send various security information to the trusted management center in real time, so that the security administrator, audit administrator and operator can monitor the connectivity status, alarm information, trusted status, trusted policy change information and trusted audit information of each terminal device in real time. However, real-time controllers usually have limited memory bandwidth and require lower message latency and high real-time characteristics. Among them, the limited memory bandwidth is because the hardware design of the real-time controller is often limited by factors such as cost, power consumption, and physical size, resulting in relatively limited memory bandwidth. This means that when processing multiple tasks and data transmission at the same time, the controller needs to efficiently manage memory resources to avoid data congestion and delay. At the same time, during the power generation process, the real-time controller needs to process a large amount of field data and control instructions. These data include sensor readings, equipment status, control parameters, etc., which are generated at a high frequency and need to be processed in real time. This large amount of data processing demand poses a challenge to the memory bandwidth of the controller. Lower message latency and high real-time requirements are because the power generation process has high requirements for control accuracy. In order to achieve precise control of the power generation process, the real-time controller needs to respond quickly and process various control instructions and feedback data. Any message delay may lead to a decrease in control accuracy and even cause safety accidents. In addition, the low latency characteristics of the real-time controller help maintain the stability of the system. During the power generation process, if an abnormal situation occurs (such as equipment failure, parameter abnormality, etc.), the real-time controller needs to respond immediately and take corresponding control measures to prevent the situation from deteriorating. High real-time performance can ensure that these control measures can take effect in a timely manner, thereby ensuring the stable operation of the system. In addition, with the continuous advancement of power generation technology and the continuous development of the power market, power generation companies have higher and higher requirements for real-time control systems. They hope that the system can provide faster, more accurate and more reliable control services to meet the growing power demand and complex power market environment. Therefore, in order to meet the high requirements of the power generation process for control accuracy, system stability and business needs, the real-time controller needs to have lower message latency and high real-time characteristics.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below. It should be understood that the following drawings only show some embodiments of the present invention. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without creative work.

[0017] Figure 1 Flow chart of a message sending method of a trusted DCS real-time control software for a power plant according to an embodiment of the present invention; Figure 2 Schematic diagram of a message sending method for trusted DCS real-time control software of a power plant according to an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can also obtain other embodiments without making creative work.

[0019] See also Figure 1-2 The message sending method of the trusted DCS real-time control software of a power plant according to an embodiment of the present invention mainly includes: S1. During the operation of the trusted DCS real-time control software, the trusted alarm information, trusted jump information, trusted status information, trusted policy information and trusted audit information are collected and sent to the trusted message processing center in the form of messages respectively; S2. The trusted message processing center classifies the received messages and sends them in order of priority. If it is a trusted alarm message, it is sent to the trusted alarm management center; if it is a trusted audit message, it is sent to the trusted audit management center; if it is a trusted status message, a trusted policy message or a trusted jump message, it is sent to the trusted business management center; the priority order is: trusted alarm message, trusted status message, trusted policy message, trusted jump message and trusted audit message; In the step where the trusted message processing center classifies the received messages and sends them in order of priority, the trusted message processing center records a timestamp TS_A each time it sends a message.

[0020] The trusted message processing center uses the current time to subtract the timestamp TS_A of the last message sent to obtain the time interval TI_B according to the message type. If the time interval TI_B is less than the set heartbeat timeout, the trusted heartbeat information is discarded; if TI_B is greater than or equal to the set time, the corresponding trusted heartbeat information is issued.

[0021] In a possible implementation, the collected trusted alarm information, trusted jump information, trusted status information, trusted policy information, and trusted audit information are packaged separately using a unified message format and then sent to a trusted message processing center.

[0022] In a possible implementation manner, the trusted alarm information, the trusted jump information, the trusted status information, the trusted policy information and the trusted audit information are respectively sent to the trusted message processing center through a local socket mechanism.

[0023] Local Sockets (also called Unix domain sockets or IPC (Inter-Process Communication) sockets) are a mechanism for communication between different processes on the same machine. Compared with TCP / IP sockets, local sockets do not communicate through the network stack, so they are usually faster and more efficient, and avoid network configuration and permission issues.

[0024] Local sockets have fast transmission speeds because data does not pass through the network stack. Local sockets are more secure because data does not leave the local machine. Compared with TCP / IP sockets, local sockets take up fewer system resources. Local sockets do not need to deal with complex concepts such as network addresses and ports. There are two main types of local sockets, namely stream sockets (SOCK_STREAM) and datagram sockets (SOCK_DGRAM). Stream sockets (SOCK_STREAM) provide connection-oriented, reliable, ordered, byte stream-based services, similar to TCP. Datagram sockets (SOCK_DGRAM) provide connectionless, unreliable, fixed maximum length message services, similar to UDP.

[0025] The basic steps to use a local socket (using C language as an example) include: (1) Create a socket. Use the socket() function to create a new socket, but set the domain parameter to AF_UNIX or AF_LOCAL (depending on the system). (2) Bind the socket. For the server, use the bind() function to bind the socket to a Unix domain address, which is usually a path name in the file system. (3) Listen for connections (only applicable to stream sockets). If the server needs to accept connections from clients, it must call the listen() function. (4) Accept connections (only applicable to stream sockets). The server uses the accept() function to wait for and accept connection requests from clients. (5) Connect (only applicable to clients). The client uses the connect() function to connect to the socket on the server. (6) Data transmission. Whether it is a server or a client, you can use the send() or recv() function (or write() and read() functions, depending on the system) to send and receive data. (7) Close the socket: After the communication is completed, use the close() function to close the socket.

[0026] Since the pathname of a local socket is visible in the file system, it needs to be properly protected to avoid unauthorized access. On some systems, the bind() call may fail if the server process does not delete the old file before binding the socket. Since local sockets do not go through the network stack, they cannot be used for cross-machine communication. Local sockets are a powerful and flexible way of inter-process communication, especially suitable for applications that require high performance and / or high security.

[0027] In a possible implementation, in the step where the trusted message processing center classifies the received messages and sends them in order of priority, the trusted message processing center takes out the destination IP and message type in the message header, classifies them according to the message type, and sends the received messages according to the destination IP.

[0028] The destination IP (also known as the target IP) refers to the destination address of the data packet, that is, the IP address of the device to which the data packet is to be delivered. It is the end point of the data packet and is used to identify the specific device to which the data packet should be sent in network communications.

[0029] The destination IP address is the final destination identifier of the data packet when it is transmitted in the network, ensuring that the data packet can be accurately delivered to the target device. The router selects the best path based on the destination IP address of the data packet to ensure that the data packet can reach the destination quickly and safely. The destination IP address is also a key component of network security. By monitoring and filtering IP addresses, network administrators can identify malicious activities and prevent unauthorized access to the network. The difference between the destination IP and the source IP is that the source IP address refers to the source address of the data packet, that is, the IP address of the device that sends the data packet. It is the starting point of the data packet and is used to identify which device the data packet is sent from. Corresponding to the destination IP address, the source IP address and the destination IP address together constitute the basic information of data packet transmission in network communication, ensuring the correct transmission of data packets in the network.

[0030] Furthermore, the setting time described in the embodiment of the present invention is 5s.

[0031] The trusted message processing center of the embodiment of the present invention is a comprehensive information processing platform, which ensures the authenticity and reliability of received messages through specific mechanisms and technical means, and effectively processes, analyzes and distributes the messages.

[0032] The main functions of the trusted message processing center include message reception, message verification, message processing, message analysis, and message distribution. Message reception refers to receiving messages from various message sources. Message verification refers to verifying the authenticity, integrity, and legitimacy of the received messages to ensure the credibility of the messages. Message processing refers to parsing, classifying, and sorting the verified messages for subsequent analysis and distribution. Message analysis refers to using big data, artificial intelligence, and other technical means to conduct in-depth analysis of messages and extract valuable information. Message distribution refers to distributing the processed messages to the corresponding recipients according to predetermined rules or user requests.

[0033] With the support of the method of the present invention, the priority of important trusted information can be improved within a limited bandwidth, and lower latency can be achieved to ensure higher performance, higher reliability and security of the entire trusted DCS control software system.

[0034] Another embodiment of the present invention further provides a message sending system for trusted DCS real-time control software of a power plant, comprising: The information collection module is used to collect trusted alarm information, trusted jump information, trusted status information, trusted policy information and trusted audit information during the operation of the trusted DCS real-time control software, and send them to the trusted message processing center in the form of messages; The message classification and sorting sending module is used for the trusted message processing center to classify the received messages and send them in order of priority. If it is a trusted alarm message, it is sent to the trusted alarm management center; if it is a trusted audit message, it is sent to the trusted audit management center; if it is a trusted status message, a trusted policy message or a trusted jump message, it is sent to the trusted business management center; the priority order is: trusted alarm information, trusted status information, trusted policy information, trusted jump message and trusted audit information; In the step of the trusted message processing center classifying the received messages and sending them in order of priority, the trusted message processing center records a timestamp TS_A each time it sends a message.

[0035] The trusted message processing center uses the current time to subtract the timestamp TS_A of the last message sent to obtain the time interval TI_B according to the message type. If the time interval TI_B is less than the set heartbeat timeout, the trusted heartbeat information is discarded; if TI_B is greater than or equal to the set time, the corresponding trusted heartbeat information is issued.
