Embodiment 1
[0035] Please refer to figure 1 , the present application discloses a nuclear power plant DCS off-line database management system, which includes an off-line database server 1 and an off-line logic analysis client 2, which will be described separately below.
[0036] The offline database server 1 mainly includes an analysis module 11 , an extraction module 12 and a reconstruction module 13 . Wherein, the parsing module 11 is used to access the online control database L1 of the DCS to parse and obtain the data structure of the online control database L1, where the online control logic data of the nuclear power unit is stored in the online control database L1. In addition, the online control database L1 can be a data storage device on the online server Z0.
[0037] The extracting module 12 is connected with the parsing module 11, and is used for obtaining the first control logic data from the online control database Z0 according to the data structure of the online control datab...
Embodiment 2
[0062] Please refer to Figure 8 , on the basis of the offline database management system disclosed in Embodiment 1, the present application also discloses a method for constructing a nuclear power DCS offline database, including steps S110-S130, which will be described separately below.
[0063] Step S110, the offline database server 1 accesses the online server Z0, especially the DCS online control database L1 in the online server Z0, to analyze and obtain the data structure of the online control database L1, where the online control database L1 stores the online Control logic data.
[0064] In step S120, the offline database server 1 extracts online control logic data from the online control database L1 according to the data structure of the online control database L1.
[0065] Step S130, the offline database server 2 reconstructs and encapsulates the extracted online control logic data to form offline control logic data, and stores the offline control logic data to obtain...
Embodiment 3
[0078] Please refer to Figure 10 , on the basis of the management system of the nuclear power DCS offline database disclosed in the first embodiment, and on the basis of the construction method of the DCS offline database disclosed in the second embodiment, the present application also discloses a synchronization method of the nuclear power DCS offline database, It includes steps S210-S240, which will be described separately below.
[0079] Step S210, the offline database server 1 accesses the online server Z0, especially accesses the DCS online control database L1 in the online server Z0, and extracts all or part of the data according to the data structure of the online control database L1 obtained through analysis, especially to obtain Data structure of online control database and online control logic data. In addition, the offline database server 1 can also obtain its own data structure and the format of the data structure.
[0080] In step S220, the offline database ser...
