System processed) it is equipped with complete fastener (I/O module) electric signals such as instrument, sensor are acquired, it is sent to after analog-to-digital conversion
The main frame of DCS dispatch control system, XU (DCS Communication Gateway), DCS data server, engineer station, man-machine interface database,
Real-time data base is then by the interface routine of operation on interface message processor (IMP) and wherein one equipment (regular situation is the XU in DCS system)
The data-interface being provided carries out data communication, thus realizing data acquisition.It is formed at tool time tag, survey in real-time data base
The real-time data record of the information such as roll-call, numerical value, state.
What Fig. 1 showed a kind of nuclear power station partition method provided in an embodiment of the present invention realizes flow process, and details are as follows：
Step 101, determination need to carry out assisting the nuclear power plant equipment of isolation by dcs DCS state.
Specifically, the equipment that only DCS environment is managed is possible to carry out auxiliary isolation by DCS state.Preferably
, there is the equipment of clear and definite start and stop (or switch) state to be defined as needing the nuclear power plant equipment of isolation in dcs.
The corresponding relation of step 102, the start and stop value according to described nuclear power plant equipment and barrier-like state value determines isolation
Value.
Specifically, carried out according to the needs that step 101 determines assisting start and stop value and the barrier-like of the nuclear power plant equipment of isolation
State value obtains corresponding relation to determine barrier-like state value.As shown in table 1, this table is start and stop value and the barrier-like state value of xegregating unit
Mapping table, wherein ISEC011PO represent the model of the equipment of needs isolation, and RP represents initiation value, and TP represents stop value,
RP=0, TP=1 represent that this equipment stops, and RP=1, TP=0 represent that this equipment is running, and RP, TP represent different equal to other values
Often.LC represents and shuts, C represents pass, and C. represents pass and tested, LO represents unlocking, and O represents out, I O table shows on-line operation.
Table 1
| Need the equipment of isolation | Barrier-like state value | Start and stop state value |
| ISEC011PO | LC, C, C. | RP=0, TP=1 |
| ISEC011PO | LO, O, IO | RP=1, TP=0 |
Step 103, according to described barrier-like state value, described nuclear power plant equipment is isolated or released isolation.
Specifically, according to the barrier-like state value that step 102 determines, described nuclear power plant equipment is isolated or released isolation.
If barrier-like state value is one of LC, C, C., described nuclear power station is isolated, if barrier-like state value is LO, O, IO, right
Described nuclear power station carries out releasing isolation.
In the embodiment of the present invention, obtain the start and stop value of equipment in DCS in real time, corresponding with barrier-like state value according to start and stop value
Relation confirms barrier-like state value, further according to barrier-like state value, equipment is isolated, be in real time according to equipment state carry out every
From, decrease the hidden danger that human factor is brought, improve security.
Further, in order to be entered to described nuclear power plant equipment according to described barrier-like state value described in more detailed description

Isolated instructions and instruction on the device whether to conflicting.Without conflict then printing list and isolation board.
Then return execution step 201 if there are conflict.
Step 204, printing list and isolation board.
After system judges not conflicting, printing list and isolation board.The live isolated operation personnel scene of completing sets afterwards
Configuration state, lock and listed.
Whether step 205, detection and isolation state are consistent with device context state, if it is, confirming to isolate and print perhaps
Can demonstrate,prove；If it is not, then notifying live isolated operation personnel.
After live isolated operation personnel are according to the isolation of isolated operation single pair of field conduct, before carrying out confirming isolation,
Reading equipment presence states in dcs, equipment state in shielding system and presence states are contrasted, if comparing result
Licensing is isolated and is printed in consistent then confirmation, and after confirmation isolation, field personnel can get licensing and carry out work on the spot.
If comparing result is inconsistent, shielding system notifies live isolated operation personnel, and the enforcement to isolation is corrected.
In the embodiment of the present invention, system mode is contrasted with presence states, judged that detection and isolation state is existing with equipment
Whether field state is consistent, and improves the security reliability of isolation work.
Further, in order to be entered to described nuclear power plant equipment according to described barrier-like state value described in more detailed description
Row releases isolation, and the embodiment of the present invention combines accompanying drawing 3, does described in detail below, and described releasing isolation comprises the following steps：
Step 301, etc. to be prepared release isolation.
Field personnel can get after licensing carries out work on the spot, and system etc. is to be prepared to release isolation, if complete
Work, gives back licensing, then system prepares to release isolation.
Step 302, printing solution division operation list.
After system prepares to release isolation, print solution division operation list.The live isolated operation personnel scene of then completing is delisted, takes lock
With setting state.
Step 303, judge whether system equipment status are consistent with field equipment state, if it is, confirming to release isolation；
If it is not, then notifying live isolated operation personnel.
After isolating quarantine measures recovery at the scene at the scene, it is existing in dcs that system reads relevant device in solution division operation list
Field state, system requirements setting state is contrasted with presence states, if comparing result is consistent, is shown live quarantine measures
Release on request it is allowed to release isolation.Otherwise, live isolated operation personnel are notified to be corrected.
