Specific embodiment
The method describing the equipment that present invention simulation is controlled by nuclear power station DCS system below in conjunction with the accompanying drawings in detail.
The method of the equipment that present invention simulation is controlled by nuclear power station DCS system, using DCS inner computer or network side
Formula accesses the computer within DCS, directly reads the command signal point-like of the external equipment being modeled inside DCS by network
State, and analog field device clicks through row write operation, real off the shelf software simulation DCS control to the feedback signal being modeled equipment in DCS
The process of the equipment of system, as shown in Fig. 2 by network connection to MNET network, or using computer equipment (this in OWP
Shi Wuxu extra computation machine equipment), data exchange is carried out by the MNET network of DCS system itself and I/O server, then by I/
O-server carries out data exchange, analog simulation scene with FCS (DCS field control station) by the SNET network of DCS system itself
Equipment；The computer equipment that the software running this method is loaded also can carry out network connection with gateway host, with gateway master
Machine carries out data exchange, simulates third party's field apparatus.Testing tool and the communication of server, connect using server is on limits
Mouthful, ordinary circumstance can use the network communication based on TCP/IP basic agreement, can use the Real-time data interface of standard (such as
OPC), it is possible to use the teledata bank interface (as ODBC) of standard, it is possible to use the communications protocol of customization, that is, customize is dynamic
Link built-in function, but no matter which kind of interface, all only realize data interaction, this method are not risen with crucial restrictive function.For example：
M_lngDomainNo=Device.Domain ' arranges domain name
QueryTagArr (0) .BSPName=DI ' set-point item title
QueryTagArr (0) .BSIName=Device.RD_Name ' arranges command signal point title
Ret=RDBObj.RDBTagRead (1, QueryTagArr, m_lngReplayTagNum, ReplayTagArr,
M_lngDomainNo, 1, -1) ' execution dynamic link function
Device.RD_Value=ReplayTagArr (0) .Value ' obtains return value, i.e. device directive signal point values
The method of equipment that present invention simulation is controlled by nuclear power station DCS system to implement step as shown in Figure 3:

Standby information, specifically includes
Step 3, obtains this cycle device directive signal point values.According to the facility information being loaded in server memory, survey
Trial work tool execution simulated action, is scanned the instantaneous value of corresponding device command signal point/feedback point by the cycle to server request.Institute
The cycle of stating can be arranged manually, and not cause extra burden to determine to server, generally selecting 500ms is a scanning week
Phase, this scan period is also relevant with the Refresh Data cycle of server simultaneously, and ordinary circumstance asks scan period and server count
According to the refresh cycle unanimously.
Step 4, device directive/feedback point value completes set in the server.According to setting of device characteristics database definition
Standby emulation logic model, testing tool, according to device type DeviceType in device characteristics database, judges to determine specifically
Emulation logic.Concrete grammar is the device directive signal point values reading this periodic refresh, the device directive with a upper cycle
Signal point values compare judgement, to determine whether execution equipment feedback signal point values change bit emulator.Ordinary circumstance, works as judged result
For this cycle device directive signal point values consistent with the device directive signal point values in a upper cycle in the case of, being not repeated will be right
The equipment feedback signal point values answered carry out set, with effective load reducing server process；Equipment when the two neighboring cycle
Command signal point value is compared when changing, then equipment feedback signal point values are carried out set, for example：
1. the cycle of going up：TD=0, RD=0, TP=1, RP=0；
2. this cycle：TD=0, RD=1；Judge that RD changes, execute emulation, export TP=0, RP=1.
3. the lower cycle：The intermittent scanning repeating 2. judges, and executes emulation, output.
Simulation data result passes through dynamic link function, write service device., so that a feedback point is for DI type as a example：
' first this DI point is set to forced regime
Step 5, it is synchronous with field control station that equipment state completes server.Obtain after above-mentioned emulation logic is processed
Equipment feed back signal point values write service device, server will in next process cycle, by this equipment feedback signal point values with
Field control station (FCS) carries out communication synchronization, and this action is automatically performed by DCS system, without manual intervention, server and scene
Control station completes the synchronized update that equipment in a cycle feeds back signal point values state.
Server presses the scanning emulation cycle of setting, the structure that multiplexing the 1st step has created, and repeats the 2nd～4 step and sweeps
The process retouch, judge, emulating, until stop, finish test procedure.
