2. Description of the Related Art Conventionally, as a simulation system for plant operation training of this kind, as shown in FIG.
In some cases, the training is made effective by adopting a configuration substantially equivalent to that of an actual plant. In the case of such a conventional system, a process simulator 41, which is a set of system-specific simulators modeled for each system such as a combustion system, a ventilation system, and an exhaust gas treatment system of an actual plant, corresponds to actual plant equipment of each system. However, the simulation controller 42 corresponds to a controller that controls actual plant equipment of the actual plant, and has a completely identical hardware configuration except for a control unit of peripheral equipment that is not targeted for training. . Further, the simulation controller 42 and an operator terminal 43 that allows the trainee to operate the simulation controller 42 are connected via a dedicated network 51 for a distributed control system, and the process simulator 41 and the instructor terminal 44 are connected. General-purpose network 52 such as Ethernet
The dedicated network 51 and the general-purpose network 52 are connected via a gateway 53. The gateway 53 is a data relay between networks composed of a kind of computer. The simulation controller 42 and the operator terminal 43 employ the same dedicated hardware configuration as that of the actual plant, and the dedicated network 51 has the same specifications as those used in the actual plant. On the other hand, the process simulator 41 and the instructor terminal 44 are each configured by a general-purpose computer system. Specifically, the process simulator 41 is embodied by executing a dedicated program for numerically solving a model of the plant equipment to be simulated by a mathematical model.

[0003] Such a simulation system for plant operation training is roughly classified into a type in which a facility such as a training center is separately provided and a type in which the facility is installed in the same place as an actual plant, depending on the installation location and usage. .
The former is called an off-site type, and the latter is called an on-site type. In each case, all the devices constituting the system are basically installed in one place.

[0004]

However, in the conventional simulation system for plant operation training, since all the devices constituting the system are arranged in one place as described above, the equipment cost is increased, and the training cost is increased. If the frequency of use is low and the operation rate of the system is reduced, the operation cost cannot be ignored.

[0010] The sixth characteristic configuration is, as described in claim 6 of the claims section, the above-described first, second, third, and third features.
In addition to the fourth or fifth characteristic configuration, a third method for temporarily storing control state data including the internal state of the simulation control device necessary for restarting the interrupted training when the training is interrupted.

A fourth storage device for temporarily storing internal state data including an internal state of the process simulator, and a second playback control means for controlling data transfer of the internal state data between the process simulator and the fourth storage device Is provided in the second device group, and at a predetermined time during training or when training is interrupted, the first playback control means transfers the control state data from the simulation control device to a third storage device, (2) The playback control means transfers the internal state data from the process simulator to the fourth storage device, and executes the training at the time when the training is to be resumed when the training is resumed. The first playback control means loads the control state data and the internal state data from the third storage device to the simulation control device, and the second playback control means loads the control state data and the internal state data from the fourth storage device to the process simulator. On the point.

The operation and effect will be described below. According to the first characteristic configuration, the first device group and the second device group are communicably connected to each other via a communication line. Therefore, the simulation control device of the first device group is The trainer can operate from the operator terminals of the two device groups, and can receive a simulated process signal from the process simulator of the second device group. The operator terminal and the process simulator can be received from the simulated control device. And the operation training management device can communicate with each other in the same second device group as the operator terminal and the process simulator. A signal can be output to the operator terminal and the process simulator, and conventionally, these devices are installed in one facility. It is possible to carry out the training as if you were. Here, the simulated control device generally has the same hardware configuration as the actual plant, and therefore occupies a large part of the equipment cost. However, the simulated control device is different from the second facility where the trainee performs training. Since the simulation control device is arranged in one facility, when constructing a new training facility, existing facilities can be used as the simulation control device in the first facility, or a plurality of second facilities ( (Training facility) can share one simulation control device, and the equipment cost and operation cost per training facility can be greatly reduced. Further, the data amount of the simulation control signal output from the simulation control device is larger than the signals output by the operator terminal and the process simulator. By selecting necessary signals at the operator terminal and transmitting them to the second communication device, the first communication device and the first communication device can receive necessary data in the next step within the simulation time of the process simulator. The required communication speed between the second communication devices can be secured with a smaller transmission capacity of the communication line, and as a result, the operation cost can be reduced due to the low communication cost.

According to the second characteristic configuration, the simulation is performed when there are a plurality of different second device groups, or when there is a plurality of training contents even if the second device group is single. The control device can be properly initialized.
As a result, a plurality of training contents can be provided for each second facility, and the training contents can be enhanced.
A mode in which the simulation control device is shared by a plurality of different second device groups can be adopted, and equipment costs and operation costs of the simulation control device can be distributed to a plurality of the second facilities (training facilities). Equipment cost and operation cost can be greatly reduced.

Further, according to the third characteristic configuration, the initialization of the simulation control device does not require the communication of the initial state file between the first communication device and the second communication device. It becomes possible. For example,
In the case where the initial state file is about 100 kB and the transmission speed of the communication line is 64 kbit / sec, if the first communication device is provided in the second facility regardless of this characteristic configuration, The transfer time of the state file from the first communication device to the second communication device takes 10 seconds or more, and the initialization is delayed by that much.

According to the fourth characteristic configuration, when there are a plurality of different second device groups, the training of one second device group is completed or interrupted, and the training of another second device group is completed. Is started, even if the application program of the simulation control device is different from the application program corresponding to the one second device group and the application program corresponding to the other second device group,
At the start of training, the second initialization means loads the application program from the second storage device to the simulation control device, so that the simulation control device can be properly initialized, and the other Training on two devices can be started. As a result, a mode in which the simulation control device is shared by a plurality of different second device groups can be adopted, and equipment costs and operation costs of the simulation control device can be distributed to the plurality of second facilities (training facilities).
Equipment costs and operating costs per training facility can be greatly reduced.

Further, according to the fifth characteristic configuration, similarly to the case of the third characteristic configuration, at the time of initialization of the simulation control device, the application between the first communication device and the second communication device is initialized. No program communication is required,
Quick initialization is possible.

[0016] According to the sixth aspect, the first and second playback control means can control the control state data and the internal state data at a predetermined time during the training or at least one time when the training is interrupted. By sequentially storing the data in the third and fourth storage devices, respectively, when the training is resumed after the training is interrupted, the control state data at a predetermined time during the training or at the time when the training is desired to be resumed during the training interruption is provided. And loading the internal state data from the third and fourth storage devices into the simulation control device and the process simulator, respectively, to restore the internal state of the simulation control device and the process simulator to the internal state at that time. Training can be resumed from that point. Further, the simulation controller, the third storage device, and the first playback control means are provided in the first facility, and the process simulator, the fourth storage device, and the second playback control means are provided in the second facility.
Since the control status data and the internal status data are stored in the third and fourth storage devices, respectively, or the control status data and the internal status data are stored in the third storage device, respectively. And when loading the simulation controller and the process simulator from the fourth storage device, there is no need to transfer the control state data and the internal state data between the first and second facilities, and during normal training, The communication line can be exclusively used for communication of the simulation control signal, the simulation process signal, and the like, so that communication efficiency is not reduced, and when the training is resumed, the simulation control device and the process simulator associated with the training restart are used. Quick initialization is possible.

Further, the driving training management device 20 includes a training resuming event setting unit 24 that selects from which time point the training is to be resumed when there are a plurality of event occurrence times set by the event setting unit 23, and A fifth storage device 25 for storing a training progress record file and the like is provided.

The operation of each unit during training using the system of the present invention will be described below. As shown in FIG. 3, the start of the training starts from the start-up of the system of the present invention in step S1, and subsequently, the setting of the training content is started in step S2. Specifically, in step S3, a trainee and an instructor are specified from the instructor terminal 13,
At 4, the training progress recording file at the time of the previous training, which will be described later, is read from the fifth storage device 25, and the contents such as the training date and time are displayed to confirm the details of the previous training. In step S5, it is selected whether to continue the previous training or start a new training.

When starting a new training, step S
In step 6, training settings such as selecting a training scenario are performed. Furthermore,
According to the training scenario, the event setting means 23
At that time, an event capable of reproducing the training or resuming the training after the training is suspended is added at the time of the training suspension, for example,
At a certain time interval, an event occurrence time point to be selectively generated at the time of occurrence of an abnormality, at the time of an alarm, or at the time of transition to a training stage is set. Subsequently, in step S7, the initial values of the simulation controller 2 and the process simulator 11 are set in a predetermined procedure, and the process proceeds to step S10, where training can be started.

The initialization of the simulation controller 2 is executed in the following manner. The driving training management device 2
0 transmits a control signal specifying the training content set at the instructor terminal 13 to the gateway 4 via the second communication device 16, the communication line 8, and the INS transmitting / receiving device 5, and The initialization means 3 in

The device 2 is initialized. It is assumed that the second communication device 16, the INS transmitting / receiving device 5, and the gateway 4 are always in operation or at least in step S1.

On the other hand, if it is selected to continue the previous training in step S5, and if there are a plurality of event occurrence times set by the event setting means 23 in the previous training in step S8, the training is restarted from any time. Is selected from the instructor terminal 13. Specifically, the training resumption event setting means 24 displays the plurality of event occurrence points on the screen, selects one event occurrence point based on the input from the instructor terminal 13, and selects the driving training management apparatus 20.

This is transmitted to the playback control means 22. Subsequently, in step S9, the first playback control unit 35 stores the control state data D stored in the third storage device 33.
The control state data D at the time of the event occurrence set by the training resumption event setting means 24 is loaded into the simulation control device 2 and the second playback control means 2
2 loads the simulation state data S at the time of the event occurrence set by the training resumption event setting means 24 from the simulation state data S stored in the fourth storage device 21 into the process simulator 11. Then, the simulation controller 2 and the process simulator 11 are set to the execution start state, and the process proceeds to step S10, where the training can be started.

As shown in FIG. 4, after the training is started in step S10, the training progresses based on the training scenario. It is determined whether or not the set event has occurred. If the set event has occurred, the control state data D is stored in the third storage device 33 in step S12, and the simulation control signal C and the internal state data are stored. The simulation state data S consisting of X is stored in the fourth storage device 21 and is stored until the end of each training.

When training is interrupted during training, or
When the training is to be terminated, it is determined in step S13 whether the training is to be interrupted, to be terminated or to be continued. When the training is to be suspended or to be terminated, the control state data D is stored in the third storage device 33 in step S14. Then, the simulation state data S including the simulation control signal C and the internal state data X is stored in the fourth storage device 21, and is stored in the third storage device 33 and the fourth storage device 21 in step S15. All the control state data D and the simulation state data S which have been stored are stored in the third storage device 33 and the fourth storage device 21 as necessary.
Are transferred to predetermined storage areas provided for each trainee in the non-volatile storage device attached to each of them, and stored and stored.

Subsequently, in step S16, a training progress recording file in which the progress of the training is recorded in a predetermined format is generated and stored in the storage area provided for each trainee in the fifth storage device 25. In step S17, the training progress record file is printed in a predetermined format, and the training is completed. At this point, the operation of the system of the present invention can be terminated, another trainee can be used continuously, or training can be started from another training facility.

According to the system of the present invention, although not shown in FIG. 3, during the training after step S10, the training is temporarily stopped, and the event set by the event setting means 23 has already occurred. If so, one of the generated events is selected, and the control state data D at the time of the event occurrence is transferred to the simulation controller 2 and the simulation state data S is transferred to the process simulator 11. Thus, it is possible to restart the training from the time when the event occurs.
