Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a communication system between a power plant DCS and an external server. Background Technology
[0002] In recent years, with the construction of smart thermal power plants, some third-party manufacturers have developed specialized intelligent control and optimization algorithms for thermal power plants to support the daily operation of the plant's own DCS (Distributed Control System). Examples include intelligent soot blowing control algorithms, intelligent combustion control algorithms, intelligent desulfurization control algorithms, and intelligent denitrification control algorithms. Since these control algorithms typically require significant CPU (Central Processing Unit) or GPU (Graphics Processing Unit) computing resources, and the thermal power plant's own DCS system usually cannot provide sufficient computing resources, these algorithms are typically run on external servers.
[0003] In some related technologies, the DCS (Distributed Control System) of thermal power plants connects directly to external servers via a network so that algorithms running on the external servers can support the daily operation of the DCS.

[0032] The following explains some terms and concepts used in the embodiments of this application:
[0033] DCS (Distributed Control System) is a computerized control system used for industrial process control and automation. In thermal power plants, DCS is mainly used to monitor and control the entire power generation process, including the operation of key equipment such as boilers, steam turbines, and generators.
[0034] The following is combined Figure 1 and Figure 2 Let me explain.
[0035] Firstly, see [the following] Figure 1 This application provides a communication system between a thermal power plant's DCS and an external server, comprising:
[0036] DCS module 101;
[0037] Communication hardware module 102, the first terminal of which is electrically connected to DCS module 101; and,
[0038] An external communication module 103 is provided, one end of which is electrically connected to the second end of the communication hardware module 102. The external communication module 103 is adapted to communicate with an external server cluster 104.
[0039] In this embodiment, by setting a communication hardware module 102 and an external communication module 103 between the DCS module 101 and the external server cluster 104, the direct connection between the DCS module 101 and the external server cluster 104 is avoided, thereby improving the data communication security between the DCS of the thermal power plant and the external server.
[0040] It is understood that the aforementioned DCS module 101 can be a computer device running a DCS system.
[0041] In one example, the external communication module 103 and the external server cluster 104 can both be deployed in the same network environment to achieve communication connection between the external communication module 103 and the external server cluster 104.
[0042] In one example, the communication connection between the external communication module 103 and the external server cluster 104 can be achieved through a network protocol, which may include at least one of the following: TCP / IP (Transmission Control Protocol / Internet Protocol), UDP (User Datagram Protocol), and OPC (OLE for Process Control) protocol.
[0043] In one example, the electrical connection between the first end of the communication hardware module 102 and the DCS module 101 can be implemented using the 485 protocol to improve data communication security.
[0044] In one alternative implementation, combined with Figure 1 and Figure 2 The communication hardware module 102 includes N communication cards 201, where N is a positive integer. The first end of each of the N communication cards 201 is electrically connected to the DCS module 101, and the second end of each of the N communication cards 201 is electrically connected to one end of the external communication module 103.
[0045] In one example, the DCS module 101 may have N DCS interfaces corresponding to the N communication cards 201, and each of the N communication cards 201 is electrically connected to its corresponding DCS interface.
[0046] In one alternative implementation, combined with Figure 1 and Figure 2 The second end of each of the N communication cards 201 is electrically connected to one end of the external communication module 103 via a twisted pair cable corresponding to that communication card 201.
[0047] In one alternative implementation, combined with Figure 1 and Figure 2 The external communication module 103 includes a first server 301, which includes at least N interfaces. The N interfaces correspond one-to-one with the N communication cards 201. The second end of each of the N communication cards 201 is electrically connected to the corresponding interface. The first server 301 is adapted to communicate with the external server cluster 104.
[0048] In one alternative implementation, combined with Figure 1 and Figure 2The external communication module 103 further includes a network switch 302 adapted to communicate with the external server cluster 104. The first server 301 further includes a port, and the port of the first server 301 is electrically connected to the network switch 302, so that the first server 301 communicates with the external server cluster 104 via the network switch 302.
[0049] In this embodiment, the first server 301 and the external server cluster 104 can be deployed in the same network environment by having both the first server 301 and the external server cluster 104 communicate with the same network switch 302.
[0050] In one alternative implementation, the first server 301 is a serial port server.
[0051] It is understood that the first server 301 is a serial port server, and thus, the N interfaces included in the first server 301 can be N serial ports.
[0052] In this embodiment, by deploying the serial port server and the external server cluster 104 in the same network environment, it is not necessary to equip the servers in the external server cluster 104 with separate serial port devices. This greatly reduces the workload and time required for serial port adaptation, and there are no special requirements for the servers in the external server cluster 104. The difficulty of system adaptation is greatly reduced.
[0053] In one alternative implementation, combined with Figure 1 and Figure 2 The external server cluster 104 includes multiple second servers 401, which are respectively connected to the network switch 302.
[0054] In one alternative implementation, combined with Figure 1 and Figure 2 Each of the plurality of second servers 401 is mapped to one of the N interfaces, and the second server 401 is adapted to interact with the DCS module 101 via its mapped interface.
[0055] In this embodiment, through the above mapping, different second servers 401 can be mapped to different interfaces of the first server 301. Through this interface, the communication card 201 connected to the interface can be connected, so that different second servers 401 can retrieve data from the DCS module 101 and / or send data that needs to be sent back to the DCS module 101 to the DCS module 101. Different second servers 401 can have different applications, thus realizing the interaction between different applications and the DCS module 101.
[0056] In one alternative implementation, the plurality of second servers 401 include hyperconverged servers and / or industrial control computers.
[0057] In one example, the aforementioned multiple second servers 401 may also include servers of different types.

[0062] An external server cluster 104 is adapted to communicate with the external communication module 103.
[0063] In one optional implementation, the communication hardware module 102 includes N communication cards 201, where N is a positive integer. The first end of each of the N communication cards 201 is electrically connected to the DCS module 101, and the second end of each of the N communication cards 201 is electrically connected to one end of the external communication module 103.
[0064] In one optional implementation, the second end of each of the N communication cards 201 is electrically connected to one end of the external communication module 103 via a twisted pair cable corresponding to that communication card 201.
[0065] In one optional implementation, the external communication module 103 includes a first server 301, which includes at least N interfaces. The N interfaces correspond one-to-one with the N communication cards 201. The second end of each of the N communication cards 201 is electrically connected to the corresponding interface. The first server 301 is adapted to communicate with the external server cluster 104.
[0066] In one optional implementation, the external communication module 103 further includes a network switch 302 adapted to communicate with the external server cluster 104, and the first server 301 further includes a port, the port of the first server 301 being electrically connected to the network switch 302, so that the first server 301 communicates with the external server cluster 104 via the network switch 302.
[0067] In one alternative implementation, the first server 301 is a serial port server.
[0068] In one optional implementation, the external server cluster 104 includes a plurality of second servers 401, which are respectively connected to the networking switch 302.
[0069] In one alternative implementation, each of the plurality of second servers 401 is mapped to one of the N interfaces, and the second server 401 is adapted to interact with the DCS module 101 via its mapped interface.
