3, IO interface: without IO interface, the button of JDT system and the driving of lamp need be considered in the lump in project.
4, one of the 220VAC power supply of 10A is provided near operator's cabinet
For realizing training purpose, this example is designed analogue system by aspects such as outward appearance, software, interface, performances.
This example requires the operator's console in JDT operator's console outward appearance, size, device layout, type selecting, acoustics and nuclear power station Site for Unit master control hall in full accord, comprise JDT dish cabinet, MM8000 workstation (display screen part), host phone, action button and pilot lamp, workstation main frame and printer etc., and the invisible parts such as operator's console internal terminal row, power supply can be different according to analog machine feature.The operator's console schematic appearance of actual design as shown in Figure 3 and Figure 4, the schematic side view that wherein Fig. 3 is operator's console, comprise control desk stage body 301, table top 302, front lower margin 303 etc., Fig. 4 is the front schematic view of operator's console, comprise liquid crystal display 401, host phone 402, host computer 403, printer 404 and blank face plate, actual concrete size and layout, be as the criterion with scene.
This example need to reach consistent with scene to the software requirement of analogue system, that is to say, platform, configuration, software and the software version of analog machine JDT system active station should be consistent with nuclear power station Site for Unit; In addition, analog machine JDT system and on-the-spot JDT system configuration and configuration are general,, after situ configuration, configuration, can directly import the use of analog machine JDT system without revising, and vice versa.
As shown in Figure 5, being connected between concrete JDT system and analog machine model, DCS system comprises: first analog machine server end operation communication program, the main detecting analog machine CDB variable of being responsible for, according to variable state, trigger corresponding JDT alerting signal, and also by JDT address virtual unit, send to client (operator station) by the peculiar agreement of MM8000, show fire alarm; Operator station is installed and the identical MM8000 client in scene, for display alarm information, and provides operation interface for operator; In addition drive required relevant configuration and file by related tool Software Create.
In this example, the effect of analog machine is exactly that emulation is carried out in the generation, the evolution that realize real real scene by the mode of simulation, approach as much as possible reality, make operator on analog machine, have kind of a sensation on the spot in person, preview, drill, train this scene, event (as fire) thereby reach on analog machine, make operator be familiar with, grasp its countermeasure, processing the operation behavior of taking in this change procedure and the information of obtaining, consistent with the information of obtaining with the operational action of taking in actual set.Realize concerning operator, the phenomenon of seeing on analog machine JDT, the result that operation causes, should be consistent with operator's result that finding, operation obtain in the time that this situation occurs actual set.
Meeting under aforementioned pacing items, analog machine, due to himself, has specific (special) requirements to system, needs to realize to comprise a series of peculiar functions such as operating mode resets, freezes, moves, recalls.
For operation and/or freezing function, JDT analogue system should or be freezed with analog machine synchronous operation, and at any time, analog machine is frozen to be stopped, and now analog machine comprises JDT system, and all states will remain on the moment of freezing, and no longer continue to change.Freeze rear cocoa and continue operation, from the moment of freezing, continue modeling event development, simulation continuously.
For store status and/or init state function, analog machine, comprises that JDT system need provide the function of store status and init state.Store status can be at any time, preserves the current state of current analog machine, so that subsequent calls.Init state, can call arbitrarily the state of storage, makes the state consistency in analog machine and store status moment.Here the state of indication, concerning JDT, should comprise the state of field apparatus, as blower fan, detector etc., and picture at master control operator station (comprising warning message, picture of opening when storage etc.) etc.
For back track function, in analog machine operational process, be separated by the set time, automatically preserve current system state, or system snapshot, by the time point of selected backtracking, can date back to the state in previous a certain moment, again proceed from this moment.
This example also provides the realization of intercommunication function, and all phones in analog machine hall are all dialed to a phone of religion control platform.All phones are dialed and are all allocated to this landline telephone, can be by programme-controlled realization.
This example also provides the realization of button and pilot lamp, will realize the collection to button state, and status information is reached to analog machine designated button state variable, because there are 15 groups of buttons at scene in requisition for 15 independent variables.Analog machine will refresh the state of 12 LED status variablees after these variablees are processed, and now, JDT analogue system should make corresponding pilot lamp light or extinguish according to these variable states.Conventionally analog machine execution cycle is no more than 200Ms.
This example is realized MM8000 client and the button of JDT operator's console and the control of pilot lamp and communication by read-write analog machine variable state.Should be able to provide the control signal of several peculiar functions as the aforementioned, as freeze/move, store status/init state, recalls etc. simultaneously.
As aforementioned known, this example is at aspect of performance, by only transmitting variable quantity, (indeclinable point does not transmit, and should not affect JDT system state) reduce network burden as far as possible, and automatically hold mode (as after fire alarm occurs, as long as state variable state is constant, this warning should keep, and the state of this point of transmission that need not be regular only transmits after this dotted state changes again).But while receiving as control signals such as init states, for reaching this requirement, tackle all data and once refresh.In addition, state refresh is timely, and the state refresh response time is no more than 1 computation period 200Ms of analog machine.
In sum, by each embodiment and instantiation, the application, for system architecture feature, adopts diversified emulation mode, when guaranteeing fidelity, reduces costs, and improves flexibility ratio.
JDT system simulation requires to provide and the on all four operation and control interface in scene to operator, be by identical information display format and mode of operation, and for bottom layer realization operator and be indifferent to.Particularly project is carried out period, is subject to the restriction of upstream data, and on-the-spot JDT system is still in debugging and performance history, and this situation further strengthens analog machine emulation difficulty.In the face of this difficult problem, the project team analyses in depth system each several part feature, adoption of innovation the solution of " the virtual transplanting+detection circuit of operator station physical object simulating+key-course model emulation ".It is man-machine interface part, adopt and on-the-spot on all four software and hardware, use MM8000 intelligent control software, and for on-the-spot backstage J DT system, as controller, boards etc., use virtual implantation technique, use simple hardware device, address and the logic of all measuring points of simulation JDT, come and upstream MM8000 communication, so just avoided buying on-the-spot expensive control system equipment, but reached identical result of use.And for the fire alarm measuring point of the bottom, directly by analog machine, utilize the emulation technology modeling of having grasped, realize the signal imitation to fire measuring point.Through in-depth analysis the protocol specification of JDT system, capture communication barrier, by independent development interface driver, the communication of implementation model and virtual unit, MM8000 man-machine interface.
Adopt this kind of scheme, guarantee the in full accord of operator station man-machine interface, and can be general with power station data, can follow the tracks of power station upgrades in time, solved power station data still in debugging, constantly changed, analogue simulation is followed the tracks of a difficult difficult problem, guarantee that interface is consistent with on-the-spot height, also can be power station JDT system configuration data verification platform is provided simultaneously.And logical layer and bottom probe use the mode of virtual transplanting and model emulation, realize the required function of system emulation, reduced number of devices simultaneously, effectively controlled project cost, and all more convenient aspect system follow-up maintenance and upgrading, flexibility ratio is large.
