The following detailed description of the distributed control system 100 in embodiments of the present application should be understood that the following description is not intended to limit the embodiments of the present application in any way.
In the embodiment of the application, a distributed control system (Distributed Control System, DCS), also called a distributed control system, is a new generation instrument control system based on a microprocessor and adopting the design principles of distributed control functions, centralized display operation, and both separate and autonomous and comprehensive coordination. The decentralized control system adopts a basic design idea of centralized control decentralized, operation and management, adopts a multi-layer hierarchical and cooperative autonomous structural form, and is mainly characterized by centralized management and decentralized control.

In the embodiment of the application, the engineer station is a workstation used for the engineer to design and modify equipment in the distributed control system, can be used for the engineer to carry out tasks such as equipment parameter setting, equipment information inquiry, equipment software programming and the like, can also be used for the workstation for monitoring and managing the equipment running state, and can carry out tasks such as equipment performance analysis, alarm processing, equipment running data recording and the like. More specifically, the engineer station may be a computer configured to configure process control software to diagnose and monitor process control station operation for use by an engineer to develop testing and maintain a distributed control system. The first engineer station 1 and the second engineer station 2 may each be a computer. The first engineer station 1 in the embodiment of the present application may be a master engineer station, and the second engineer station 2 may be a slave engineer station (for example, referred to as a slave engineer station) of the master engineer station, and in the distributed control system 100, there may be one master engineer station, a plurality of slave engineer stations, and the slave engineer station may be managed by the master engineer station.
In the present application, the second engineer station 2 may be connected to the first engineer station 1 through any type of terminal bus 3, and the first engineer station 1 and the second engineer station 2 may communicate through the terminal bus 3. For example, in some alternative embodiments, the terminal bus 3 comprises an industrial ethernet bus. Through the industrial Ethernet bus, communication between the first engineer station 1 and the second engineer station 2 can be effectively realized, and the use requirement of a distributed control system in a power plant scene is met.
In the present application, the control unit 11 of the first engineer station 1 may perform tasks of data processing and control, which is electrically connected to the storage unit 12, and the storage unit 12 of the first engineer station 1 is used to store first data, which may be a set of all data stored in the first engineer station 1 in the present application. The storage unit 12 may be any device that can be used to store data, and may include, for example, at least one hard disk, magnetic disk, and the like. In some alternative embodiments, storage unit 12 includes at least two hard disks that make up a Raid0 array. Raid0 is the type with the highest storage performance in all Raid levels, and in the present application, the requirement of data storage of the first engineer station 1 can be better met by the storage unit 12 including at least two hard disks that form the Raid0 array.
Alternatively, the storage capacity of the hard disk may be at least 300GB. The data storage requirements of the first engineer station 1 can be better met by such a hard disk. Of course, the storage capacity of the hard disk may be less than 300GB (e.g., 200GB, 250GB, etc.), or more than 300GB, as long as the requirements can be satisfied.
In the present application, the FTP server 21 included in the second engineer station 2 may be a server supporting an FTP (FILE TRANSFER Protocol) Protocol, providing a service according to the FTP Protocol, and being capable of providing a file storage and access service. In the present application, the hardware of the FTP server 21 is part of the hardware of the second engineer station 2. Alternatively, the FTP server 21 may be installed based on the FTP protocol and IIS service configuration. For example, the FTP server 21 establishes a connection with the control unit 11 through the terminal bus 3 so that the first engineer station 1 and the second engineer station 2 can transfer files through the FTP protocol, the control unit 11 of the first engineer station 1 can transfer the first data stored in the storage unit 12 to the FTP server 21 of the second engineer station 2 through the terminal bus 3 using the FTP protocol based on the received instruction signal, and the FTP server 21 can archive the first data into a designated directory to backup the first data.
The control unit 11 of the first engineer station 1 may automatically transmit the first data stored in the storage unit 12 to the FTP server 21 through the terminal bus 3 after receiving the instruction signal, which is advantageous for improving the automation degree of the distributed control system 100 when the data backup of the first engineer station 1 is performed.
For example, in some alternative implementations, a shell script may be arranged in the control unit 11 of the first engineer station 1 that automatically performs an action of transmitting the first data stored in the storage unit 12 to the FTP server 21 via the terminal bus 3, the action being performed automatically by the control unit 11 executing the shell script. For example, after the control unit 11 receives the corresponding command signal, the control unit 11 may execute the shell script, automatically backup the first data in the storage unit 12, compress the first data, mark the time, and transmit the compressed first data to the FTP server 21 of the second engineer station 2 through the terminal bus 3 based on the FTP protocol, and the FTP server 21 may archive the first data in a specified directory according to the marked time order to backup the first data. Alternatively, in addition to arranging the shell script in the control unit 11 of the first engineer station 1, the shell script may be used in combination with the Cron function, and periodically invoking the shell script to automatically complete the operations of backing up the first data in the storage unit 12, compressing the first data, and transmitting the first data to the FTP server 21, so that the FTP server 21 archives the first data in a designated directory to backup the first data. By such an alternative manner, when the first data of the first engineer station 1 needs to be fully backed up, the FTP server 21 of the second engineer station 2 can be enabled to backup the first data of the first engineer station 1 more quickly and effectively, so that the backup efficiency is improved, the operation steps are simplified, the backup requirement is met, the workload of operation staff (such as engineers and the like) is reduced, and the availability time of the first engineer station 1 is effectively improved.

The command signal can be efficiently generated by the man-machine interaction unit 13 in order to realize a backup of the first data of the first engineer station 1.
For example, the human-computer interaction unit 13 may be a keyboard of the first engineer station 1, and the instruction signal may be generated by performing a one-touch operation on the keyboard by a user (may be an engineer or the like). Or the man-machine interaction unit 13 may be a button on a display interface included in the first engineer station 1, and the instruction signal may be generated by performing a one-touch operation on the button by a user. Obviously, in this way, the purpose of carrying out backup by transmitting the first data of the first engineer station 1 to the FTP server 21 of the second engineer station 2 through the terminal bus 3 by one key can be achieved, the backup efficiency is improved, the operation steps are simplified, and the backup requirement is met. Or the man-machine interaction unit 13 may be of another type, without specific limitation.
