Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention is a simulated control panel that simulates a control panel for driving gill training, and the lamps and lights on the simulated control panel are adjusted according to the operations of trainees.
0 Technical Background of the Invention and its Problems In general, plant simulators are controlled by a computer so that the indicators etc. make the same operating sounds as the actual plant, and have the function of fully controlling the progress of the simulation from the instructor's console. Initial value data refers to the data for setting the plant state of the plant simulator at the time of starting operation training.In other words, this initial value data is the point at which the instructor wants to save it as an initial value in past operation training. Initial value data (hereinafter referred to as backtrack data) that is created as initial value data based on a request to save the plant status, and simulated plant status data for the past several tens of minutes during operation using a function called bank track (hereinafter referred to as backtrack data) ). Since these initial value data have a large size that occupies a storage device, restrictions have been placed on the initial value rLJ when saving the initial value and the cycle during backtracking. Furthermore, it was possible to provide an unlimited number of initial value data using a storage device (storage medium), but since this would complicate the process, a limit of 50 to 100 was usually set.

Therefore, when setting initial values during driving training,
It can only be set at the time when the initial value is saved or when the backtrack data has /:C1/)OL/Therefore, the plant state at the start of training is limited.
If there is a gap between the plant state at which you want to start training and the initial values you have, it is necessary to perform operations that can be considered wasteful. For example, as shown in Figure 1, if an accident or erroneous operation occurs at point A (time point is human) of the simulated characteristics, either point B, which has backtrack data dtB before the accident occurred, or the countermeasures taken after the accident occurred.・If you can only return to the 6 points that have track data dte (or the point that has initial value data by requesting to save the initial value) and want to train on what to do after an accident at point A, you can return faithfully from point B. In addition, reproducing the operation at that time places an extremely heavy burden on the operator.
In some cases, due to differences in operation timing, AA-1
: There were times when it was impossible to reach. As a result, trainees and instructors were forced to waste their efforts, and there was also a large loss of time.

Additionally, the plant simulator is equipped with a function, usually called replay, that allows past plant operations and plant movements to be repeatedly reproduced on a simulated control panel without the trainee's operation. This is a chronological record of the trainee's operations on the simulated control panel and the entire time period of the operations (hereinafter referred to as replay data), along with backtrack data. By specifying the point in time when this dog track data has, and using the replay data stored from there, the trainee's operation of the simulated control panel is reproduced in a simulated arithmetic and control device according to the stored time, Past training was being reenacted without actual sweeping.

child,! It is called t't replay function. At this time, backtrack data is used as the initial value for replay,
Also, recently, a function called permanent replay data storage that saves replay data on an external storage medium has become popular.The permanent storage data saved with this replay data permanent storage function varies depending on the capacity of the external storage medium. However, it has been common practice to store one piece of backtrack data at the start of the replay and subsequent play data as initial value data for performing the replay.

These replay data and permanently saved data can only be used with the replay function, and continuous switching to driving operation and initial value setting from this data were not performed at any point during replay, so J. This caused problems such as.

Purpose of the Invention The purpose of the present invention is to create a plant that can return to any point in time by using backtrack data and play data permanently stored data that shows past driving data. The simulation equipment is all there to go.

Summary of the Invention The present invention aims to enhance the replay function by making it possible to continuously switch to driving operation from any point during replay based on past driving data, thereby making it possible to carry out driving training in accordance with the training curriculum. This eliminates the time loss that was considered during driving training, reduces the load on V11 trainees and instructors, and enables more efficient driving training.

An embodiment of the present invention will be described below with reference to FIG.

In Fig. 2, the simulated control panel 1 is the same type and has the same functions as the control panel of the actual plant, and the operation trainee can grasp the status of the plant through various lamps, indicators, etc. on this simulated control panel 1. , various operation switches on the simulated control panel 1 are used to operate the plant. The instructor's console 2 allows the instructor to control the progress of the C simulation on the arithmetic and control unit 3 using various operation switches on the instructor's console 2, and to grasp the progress status of the simulation using various lamp indicators on the instructor's console 2. do. The arithmetic and control device 3 includes a simulation arithmetic unit 4. Arithmetic control unit 5° has a plant state data storage area 6 and a simulation content storage area 7, and control switches SZIS21SJIS4,S controlled by the arithmetic and control unit 5
The operation signal Ut from the simulation control panel 1 is input to the simulation calculation unit 4, and the command signal It from the instructor console 2 is input to the calculation control unit 5. The simulation calculation unit 4 performs simulation calculations of the characteristics of the control device in the actual plant and the physical dynamic characteristics of the plant according to the input operation signal gt, and the results are displayed on the simulation control panel 1 to represent the simulated plant state. Output as signal 0 to 1. It is output to the plant state data storage area 6 as initial value data dt representing the latest simulated plant state. The simulation calculation section 4 also has a Fast Cycle calculation function that completely reduces the time axis of the plant response time in the plant simulator to 1/n times of the actual plant response time and performs simulation calculations at full speed.

The arithmetic control section 5 fully controls the progress of the control switch -81 to S5 gold switching simulation based on the input command signal It, and outputs a display signal: t-2 representing the progress state of the simulation to the instructor console 2.

The simulation content storage area 2 stores the operation signal Ut of the simulated control panel l as replay data r representing the operation record.
t, and if it is the storage period of the pack track data, the latest initial value data dt stored in the plant state data storage area 6 is retrieved and the pack track data dt is stored in the simulated calculation unit, respectively, as shown in FIG. 4 to save in chronological order.

As shown in FIG. 1, the permanent storage area 8 stores one pack track data Bt and subsequent replay data R from the simulation content storage area 7 when a permanent storage command for replay data is received from the instructor console 2, as shown in FIG.
The details of the operation of the present invention in the configuration of 0th order or higher in which t-'i is input and stored will be explained with reference to FIG. 1 and FIG. 2. The simulated characteristics in Figure 1 are Plan!・In Figure 0, which shows the plant state at the past operation side M in the simulation device, the turbine rotation speed is shown. In addition, there was a request for permanent storage of pack track data and play data saved in the simulation content storage area 7 during past driving training, and replay data from the driver console 2 at time t1 during past driving training. The contents of the time permanent storage area 8 are shown in detail in FIG. 1. First, a case will be described in which continuous switching to operating operation is performed at any time during the simulated plant ride play. For example, from time tB to time t・Δ in the simulation content storage area 7 using the instructor console 2.
Consider the case where there is a request to play up to the point. The replay command It is sent from the instructor console 2 to the calculation control unit 5.
This replay command It is input to the arithmetic control unit 5.
When this is received, the control switch 82 is switched to the d side to bypass the operation signal Ut from the control panel I, and the control switch S3 is opened to bypass the storage in the simulation content storage area 7. And in the simulated calculation section 4,
The pack track data dtBf representing the initial value data necessary to start replay is retrieved from the simulation content storage area 7 via the control switch S2, and the data is stored in the plant state data storage area 5 as the initial value data dt of the simulated plant. Further, a display signal representing the current simulated plant state: 1-+ is output to the simulated control panel 1.

Thereafter, the replay data rtB-c-6 indicating the operation record stored in the simulation content storage area 7 is input via the control switch 'fS 2f, and the simulation calculation unit 4 calculates the simulation plant according to the replay data rtB-0. At that time, the calculation results are output to the simulated control panel 1 as a display signal at-+ representing the simulated plant state, and to the plant state data storage area 6 as initial value data dt representing the latest simulated plant state.

In this way, past driving data is replayed between times jB and jc and goes to 'C' (this is the same as the conventional method).
In the present invention, when a replay stop request is made from the instructor console 2 when an arbitrary time tA in the replay section te -tc is reached, the replay stop command It is inputted from the instructor console 2 to the calculation control unit 5, and the calculation is performed. The control section 5 switches the control switch S2 to the C side, bypasses the input of the ride play data from the simulation content storage area 7, and enables the operation signal Ut from the simulation control panel 1 to be input to the simulation calculation section 4. Furthermore, the control switch IF-83f is closed to permit storage of the ride play data and back track data in the simulation content storage area 7. At that time, by using the plant state data at time tA stored in the plant state storage area 6 without completely initializing it (continuously switching to operation from time tA, which was previously initialized). is possible.

Thereafter, the simulation calculation section 4 receives and receives the operation signal Ut of the simulation control panel 1, and performs calculations of the simulation plant in accordance with the operation signal Ht. Therefore, as shown in the dashed line in the simulated characteristics in Figure 1, it is possible to
Driving operations that are different from replays are possible. this is,
Similarly, even if the permanent storage area is all used or the play is in progress, if the arithmetic and control unit 5 receives the replay command,
By closing the control switch f85 and extracting the backtrack data and replay data from the permanent storage area 8 and resaving them in the simulation content storage area 7, the same effect as the replay request and replay stop request made by the simulation content storage area 7 can be made. I can do it.

In this way, when the plant simulation device is replaying using replay data, backtrack data, and permanently stored data, which are past operation data, a request to stop the play is made from the instructor console 2 at any point during the replay. This enabled continuous switching to plant operation. Next, replay data, which is past operation data.

A case will be described in which the state of the simulated plant is returned to an arbitrary point in time in the backtrack data and permanently stored data. For example, if you want to restore the simulated plant state to the state of the past operation data stored in the simulation content storage area 7 at an arbitrary time point th (see Figure 1), if you request the initial value setting from the instructor console 2 along with the time data th, The initial value setting request l is passed from the instructor console 2 to the calculation control unit 5, and the calculation control unit 5 switches the control switch 5l.
Switching to the lfb side bypasses the display signal quality-1 for display on the simulated control panel 1, and also switches the control switches 82f and H.
Switching to the d side, the operation signal Ut from the simulated control panel 1 (
i) Bypass. Furthermore, the control switch S3 is switched to open, thereby bypassing the storage in the simulation content storage area 7. Then, the simulation calculation unit 4 stores backtrack data dtB from the past driving data at the specified point in time to the closest one before.
The data is taken out via the control switch S2f and stored in the plant state data storage area 6 as the initial value data dt of the simulated plant. Then, the play data rtB-c after the pack track data dLB is taken out from the simulation content storage area 7 via the control switch S2, and according to the play data rtB-8,
The conventional Fast Cycle function included in the simulation calculation unit 4 is used to perform calculations at C high speed until the designated time th-.

(At this time, of course, the display old name 1 on the simulated control panel 1 and the operation signal Ut from the simulated control panel 1 are the control switch 81
．． They are each bypassed by S2. ) When the simulation calculation section 4 completes the simulation calculation up to the designated time point jA, the simulated plant state data at that time point tA is stored in the plant state data storage area 6 as initial value data dtA. The arithmetic control section 5 then controls the control switch S.
l f Switch to B side Display signal quality to simulated control panel 1 -
1 output, and the control switch s z r, (
Switch to the c side and enable the input of the operation signal Ut from the simulated control panel 1. Furthermore, the control switch 'fS, ? Switch to Close to allow backtrack data and replay data to be saved in the simulation content storage area.

Next, the simulation calculation unit 4 extracts the initial value data dtAi at the designated time tA from the plant state data storage area 6, and converts the data into a display signal ot-+ representing the simulated plant state at the designated time t^. It is output to the control panel 1 via the control switch 5zfc. This makes it possible to set the initial value of past operation data in the simulation content storage area to the same simulated plant state as a human at any point in time. Similarly, initial values can be set at any point in time for past driving data stored in the permanent storage area for replay purposes. in this case,
First, after the calculation control unit 5 receives the p period value setting command Itf, the calculation control unit 5 closes the control switch S5 and stores one backtrack data Bts in the permanent storage area.
And the subsequent glue play data Rts-yf is saved again to the simulation content storage area 7 via the control switch S5f. After that, the operation is the same as when the simulation content storage area 7 is used. However, since the pack track data is not Bts L, this is used, and the replay data is Rta-1! use. Therefore, compared to when the simulation content storage area 7 is used, the simulation calculation section 4 performs Fast C between time ts -f,B.
The completion of initial value setting is delayed due to the ycle calculation.

In this way, by using the replay data, pack track data, and permanently stored data that are past driving data used by the replay function, it is possible to set the initial value at any point in time for the past driving data.

In a plant simulation device, the conventional replay start point is
It has been impossible to start replaying only the backtrack data at a certain point in the past driving data, and replaying only an arbitrary time period of the past driving data. For example, the first
Past driving data as shown in the figure is stored in the simulation content storage area 7 and permanent storage area 8, respectively.
Any time period jA - jA among the past driving data
Conventionally, if you want to replay the point jB, you can use the simulation content storage area 7.
Therefore, if permanent storage area 8 is used, time tS
At time t, replay cannot be started unless
It took a waste of time to complete the process up to h, and it was sometimes longer than the actually necessary play section iA-i'.

However, by applying the present invention, it has become possible to replay past driving data only at any time period. For example, if you want to replay an arbitrary time period jA% th' in the past driving data shown in FIG. First Cyc
le calculation and use it as the initial value, so if you use the obtained initial value as the initial state of the simulated plant at the time of replay, it seems like a waste of time from the start of conventional play to any point th. The waiting time will be reduced, and you will be able to replay only the necessary time slots.

As mentioned above, any past operation data that has been used in the past can be
By being able to replay only the time period, the replay function has been enhanced, making driving training more efficient.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, by effectively using replay data, backtrack data, and permanently stored data indicating conventional past driving data, the present invention can be applied to any point in time during past driving training. It is now possible to go back to the conventional plant initial state, which was limited in number, and have a wide range of initial values.

Furthermore, when replaying past driving data, it is possible to continuously switch to driving operation from any point in time, and by being able to replay past driving data only at any time period, a wide range of replay operations is possible. 6 As a result of the above, it is possible to conduct driving training in accordance with the L, Vl1m curriculum without the time loss that was considered during driving training, and to reduce the burden on trainees and instructors, resulting in more efficient driving training. becomes possible.
