For example, referring to fig. 5, a maintenance method for a security level DCS of a nuclear power plant may be implemented by a lower computer consisting of N cabinets, a data server, a collaboration server, and a collaboration client. Referring to fig. 5, the collaboration server is designed to perform business processing rather than data processing, and the business and data are separated from the overall architecture to ensure that the whole system can operate more stably in the future.
The implementation process is as follows: the cooperative client sends a monitoring request to the cooperative server, and a service unit of the cooperative server judges whether monitoring data of the monitoring request of the cooperative server is subscribed to the data server or not, if the monitoring data is not subscribed to the data server, for example, the cooperative client sends the monitoring request to monitor diagnostic data of a lower computer for the first time, at the moment, the service unit initiates a data subscription request to the data server, thereby subscribing related monitoring data; and at the same time, joining the cooperative client side sending the monitoring request into a data forwarding object list, and waiting for data forwarding. If the monitoring request is not sent for the first time to monitor the diagnostic data of a lower computer, the co-processor sends the monitoring data corresponding to the monitoring request to one or more co-clients sending the monitoring request after receiving the monitoring request.
At this time, the data server continuously receives the monitoring data sent by the processor of the cabinet of the lower computer, analyzes the monitoring data and stores the monitoring data; and forwarding corresponding monitoring data to the cooperative client according to the data subscription condition.
Further, the data server comprises a master server and a slave server which are redundant from each other;

The data server ensures the reliability of data through the master server and the slave server with master-slave redundancy, and when one data server host fails, the other host can dynamically switch to continue to store historical data. When the master server and the slave server simultaneously fail, the collaboration server can be switched to be directly connected by adopting the protocol converter through user operation, and related functions can be continuously executed. According to the double-server design of the redundancy mode, load balancing is performed, when the master server and the slave server are normally used, one server is responsible for storing data and the other server is responsible for providing data query service; when one of the servers fails, the other server is responsible for storing and warehousing data and providing data query service; the treatment mode has the following advantages:
the writing and reading of the data are split, so that the expenditure of hardware resources can be reduced, and the adaptability of the whole system is improved.
The master-slave redundancy mode of the double servers can provide guarantee for long-term stable operation of the service, and when single-point faults occur to the equipment, the service can be ensured not to be interrupted.
The backup function of the double servers is actually that the data is backed up in real time, and when a set of backup data ensures that the system has single-point faults, the system can ensure that a complete piece of data exists in the system to provide data service all the time, and the condition of large-scale fault of the data can not occur.
Further, the master server and the slave server of the master-slave redundancy each further comprise: the data query unit is used for querying and reading the monitoring data in the storage unit; and the data subscription unit is used for completing data subscription according to the subscription request.
Further, the collaboration server further includes:
the business service unit is used for being respectively connected with the cooperative client, the data subscription unit and the forwarding unit; and
And the scheduling service unit is used for being connected with the cooperative client and the business service unit respectively.
Further, the collaboration server is respectively connected with the master server, the slave server and the lower computer; when the master server or the slave server fails, the cooperative server communicates with the master server or the slave server without failure; when the master server and the slave server fail, the collaboration server communicates with the lower computer.
The scheduling service unit of the collaboration server is mainly responsible for managing client connection, maintenance of service and the like, and the service provides specific service processing implementation interfaces in each project. When the cooperative clients open projects, a scheduling service unit of the cooperative server is connected, the scheduling service unit starts service corresponding to the projects, after the starting, when the cooperative clients start monitoring, the service records client information and subscribes monitoring data of corresponding monitoring stations to the data server, the data server sends the monitoring data uploaded by the lower computer to the service unit, and the service unit distributes the monitoring data to each monitoring client (namely the cooperative client for monitoring) according to the client information and displays the data on the monitoring client.
In a third aspect, embodiments of the present invention provide a computer-readable storage medium having instructions stored thereon that, when executed on a computer, perform the maintenance method for a nuclear power plant security level DCS.
Therefore, the design of the master-slave redundant data server of the safety level DCS of the nuclear power plant has high reliability; the main server, the auxiliary server and the cooperative server are respectively configured, so that the separation and fault tolerance of the service are effectively realized; in addition, the embodiment of the invention has a better online cooperative function, realizes simultaneous monitoring of the diagnosis data of a plurality of cabinets and data sharing among the cooperative clients of a plurality of engineer stations, thereby facilitating maintenance personnel to identify, locate and replace internal fault equipment of the system in time through relevant fault diagnosis information monitored by each cooperative client.
