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 realization process is as follows: a cooperative client sends a monitoring request to a cooperative server, a business service unit of the cooperative server judges whether monitoring data of the monitoring request of the cooperative server is subscribed to a data server, if the monitoring data is not subscribed to the data server, for example, if the cooperative client sends the monitoring request to monitor diagnostic data of a certain lower computer for the first time, the business service unit sends a data subscription request to the data server, and accordingly, relevant monitoring data are subscribed; and meanwhile, adding the cooperative client sending the monitoring request into a data forwarding object list to wait for data forwarding. If the monitoring request is not sent for the first time to monitor the diagnostic data of a certain lower computer, the cooperative processor sends the monitoring data corresponding to the monitoring request to one or more cooperative clients sending the monitoring request after receiving the monitoring request.

When the main server and the slave server simultaneously have faults, the cooperative server can be switched to be directly connected by adopting the protocol converter through user operation, and related functions are continuously executed. The dual-server design of the redundancy mode makes load balance, when the master server and the slave server are normally used, one server is responsible for storing and warehousing data, and the other server is responsible for providing data query service; when one server fails, the other server is responsible for storing and storing data and providing data query service; the processing mode has the following advantages:
the data writing and reading are separated, 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 a single-point fault occurs to the equipment, the service can be guaranteed not to be interrupted.
The backup function of the double servers is actually to perform real-time backup of data, and when a set of backup data guarantees that a single point of failure occurs in the system, it can be guaranteed that complete data exists in the system from beginning to end to provide data service, and the situation of large-scale data fault can not occur.

The scheduling service unit of the collaboration server is mainly responsible for managing client connection, maintenance of business services and the like, and the business services provide specific business processing implementation interfaces in each project. When a project is opened by the cooperative client, a scheduling service unit of the cooperative server is connected, the scheduling service unit starts a business service corresponding to the project, after the start, when the monitoring is started by the cooperative client, the business service records client information and subscribes monitoring data of a corresponding monitoring station to the data server, the data server sends the monitoring data uploaded by the lower computer to the business service unit, and the business service unit distributes the monitoring data to each monitoring client (namely the cooperative client for monitoring) according to the client information and performs data presentation on the monitoring client.
In a third aspect, an embodiment of the present invention provides a computer-readable storage medium, where instructions are stored, and when the instructions are executed on a computer, the maintenance method for a nuclear power plant safety level DCS is performed.
