Specific embodiment
The method for the equipment that the present invention is described in detail simulation is controlled by nuclear power station DCS system with reference to the accompanying drawing.
The method for the equipment that present invention simulation is controlled by nuclear power station DCS system, utilizes DCS inner computer or network side
Formula accesses the computer inside DCS, and the command signal that the external equipment being modeled inside DCS is directly read by network is dotted
State, and analog field device clicks through row write operation, real off the shelf software simulation DCS control to the feedback signal for being modeled equipment in DCS
The process of the equipment of system, as shown in Fig. 2, by network connection to MNET network, or use computer equipment (this in OWP
Shi Wuxu extra computation machine equipment), data exchange is carried out by the MNET network and I/O server of DCS system itself, then by I/
The SNET network progress data exchange of O-server and FCS (DCS field control station) by DCS system itself, analog simulation scene
Equipment；The computer equipment that the software for running this method is loaded can be also connected to the network with gateway host, with gateway master
Machine carries out data exchange, simulates third party's field device.The communication of testing tool and server connects using server is on limits
Mouthful, the network communication based on TCP/IP basic agreement can be used in ordinary circumstance, and the Real-time data interface of standard can be used (such as
OPC), it is possible to use the teledata bank interface (such as ODBC) of standard, it is possible to use the communications protocol of customization, that is, the dynamic customized
Link library function, but no matter which kind of interface, be all only to realize data interaction, crucial restrictive function do not played to this method.Such as:
Domain name is arranged in m_lngDomainNo=Device.Domain '
QueryTagArr (0) set-point .BSPName=DI ' title
Command signal point title is arranged in QueryTagArr (0) .BSIName=Device.RD_Name '
Ret=RDBObj.RDBTagRead (1, QueryTagArr, m_lngReplayTagNum, ReplayTagArr,
M_lngDomainNo, 1, -1) ' execute dynamic link function
Device.RD_Value=ReplayTagArr (0) .Value ' obtains return value, i.e. device directive signal point values
The specific implementation step of the method for the equipment that present invention simulation is controlled by nuclear power station DCS system is as shown in Figure 3:
Step 1 is pre-formed device characteristics database.By object oriented languages such as testing tool or VB, VC, read
Facility information in device characteristics database.Wherein, device characteristics database is recorded according to physical device operation instructions
A kind of format that can be read of instruction/feedback characteristics conversion, facility information includes but is not limited to following information: being modeled implementor name
Claim, equipment feedback signal point title, device command signaling point title, device type information, device Domain number.
Step 2, facility information are all loaded onto memory.It, will be with using object oriented languages such as testing tool or VB, VC
Upper facility information reads server memory from device characteristics database, and establishes a structural body, for storing multiple set
Standby information, specifically includes
Step 3 obtains this period device directive signal point values.According to the facility information being loaded into server memory, survey
Trial work tool executes simulated action, requests to scan the real value for corresponding to device directive signaling point/feedback point to server by the period.Institute
Manual setting can be carried out by stating the period, and not cause additional burden to determine server, generally selecting 500ms is a scanning week
Phase, while the scan period is also related with the Refresh Data period of server, ordinary circumstance requests scan period and server count
It is consistent according to the refresh cycle.
Step 4, device directive/feedback point value complete set in the server.It is set according to what device characteristics database defined
Standby emulation logic model, testing tool judge to determine specific according to the device type DeviceType in device characteristics database
Emulation logic.Specific method is the device directive signal point values for reading this periodic refresh, the device directive with a upper period
Signal point values compare judgement, to determine whether to execute the displacement emulation of equipment feedback signal point value.Ordinary circumstance works as judging result
For under this period device directive signal point values and the device directive signal point values unanimous circumstances in a upper period, being not repeated will be right
The equipment feedback signal point value answered carries out set, the load of server process is effectively reduced；When the equipment in two neighboring period
Equipment feedback signal point value is then carried out set compared to when above changing by command signal point value, such as:
1. the upper period: TD=0, RD=0, TP=1, RP=0；
2. this period: TD=0, RD=1；Judge that RD changes, execute emulation, exports TP=0, RP=1.
3. the lower period: repeating intermittent scanning judgement 2., and execute emulation, output.
Simulation data result passes through dynamic link function, write service device., by taking a feedback point is DI type as an example:
' this DI point is first set to forced regime
Step 5, it is synchronous with field control station that equipment state completes server.By what is obtained after the processing of above-mentioned emulation logic
Equipment feedback signal point value write service device, server will in next process cycle, by the equipment feedback signal point value with
Field control station (FCS) carries out communication synchronization, which is automatically performed by DCS system, is not necessarily to manual intervention, server and scene
Control station completes the synchronized update of equipment feedback signal point state of value in one cycle.
Scanning emulation cycle of the server by setting, the structural body that multiplexing step 1 has created, the 2nd~4 step of repetition are swept
The process retouch, judge, emulated, until stopping, finish test procedure.
