Abstract

PURPOSE:To enable a large amount of a monitoring record to be effectively and surely retained in a short time by taking the hard copy of the contents of a display indicative of the condition of a plant. CONSTITUTION:The condition of a plant is displayed on a display 17. Hard copy request judging means 18 judges the requirement of a hard copy from the information of a process memory 14 and actuates display data storage means 19 when a request in present. The means 19 stores data from display means 16 which are compressed by display data forming means 15 in a display memory 20 and judges the propriety of the hard copy. When the hard copy is proper, the means 19 actuates hard copy means 21. When the copy request is generated even when the actuation of the hard copy means 21 is not permitted, the storage means 19 transfers and stores display data to and in the memory 20, respectively. When a hard copy apparatus 22 comes into an executable condition for the hard copy, the means 21 is actuated, stored data are recorded on a hard copy record and these operations are continued until no stored data are present in the memory 20.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is a monitoring system that monitors the status of a plant using a display device and records the status by making a hard copy of the display contents. Regarding recording devices, the application is particularly considered in plants where intermittent operation is performed and the amount of hard copies required increases intermittently.

(Prior Art) An example of the configuration of a conventional device is shown in FIG. 4. Reference numeral 11 indicates a plant, 12 a process input device, and 13 a process data processing means for creating process data for determining a process state from input data. , 14 is a process information storage device (hereinafter referred to as process memory) for storing process data, 15 is a display data creation means for creating display display data from the process data, 16 is a display display means, 17 is a display device, 18 is a A hard copy request determining means determines whether or not a hard copy is necessary based on process data, 21 is a hard copy means, and 22 is a hard copy device. Explain the operation. The state of the plant 11 is input to the arithmetic processing unit via the process input device 12, and processed by the process data processing means 13, such as engineering value conversion and logical operations, which is set in advance for each plant, so that the process state can be determined. 1 display data creation means 15 stores the process data in the process memory 14 as the process data of the process memory 14 and the process device! ! Based on the current display state of 217, the data is processed into data (hereinafter referred to as display data) that can be displayed on the display device 17, and the display means 16 is activated.

The display means 16 outputs the created display data to the display device 17 to display the process status in real time. This allows the operator to monitor the plant. On the other hand, based on the information in the process memory 14, the hard copy request determining means 18 determines whether the plant status is in a hard copy request state specified in advance by the system (for example, an operator has requested a hard copy, a plant abnormality has occurred, an operation has stopped, etc.). ).
It is determined whether or not the hard copy is requested, and if there is a hard copy request, the hard copy means 21 is activated. Hard copy means 2
1 to the hard copy device 122, hard copy recording is performed based on the display data output from the display means 16. The hard copy request determination means and the display data creation means can record the state of the plant by, for example, six or more operations activated when the process state changes.

(Problems to be Solved by the Invention) However, such conventional devices have the following problems. In other words, when monitoring a plant such as a tokamak-type fusion device that performs pulse operation and many events occur in a short period of time during operation, the amount of measurement data increases intermittently. The data is processed and displayed on a display device to notify the operator of the plant status, and the necessary screens are made into hard copies and records are kept, but when there is a large amount of data compared to the period of downtime. In many cases, it was not possible to record all necessary information in hard copy. With conventional devices, the amount of recording is limited by the speed of the hard copy device.

It is not possible to keep up with the update speed of the display device or process memory, resulting in lags in recording.

This situation is shown in the time chart of FIG. 5. Line A indicates the operating state, and the shaded area 31 indicates the operating state. Line B shows the state of process data processing, and the shaded area 32 indicates that the process memory is being updated. Line C shows the display state of the display device, 331-33. 5 shown in
Five arrows indicate display update requests, and ω to ■ indicate process statuses. Line D shows the status of the hard copy device, and the shaded area is during hard copy, 34□~34
3 is the hard copy command, ■, ■, ■ are the screens, respectively.
(3), indicates that ■ is being hard-copied. During operation, it captures process data, and when it is not operating, it notifies the operator of the status of the plant during operation on five screens.

At the same time, it is necessary to make hard copies of all five screens, but during the suspension period there was no time to take three hard copies, and by the time the three screens were taken, the process data had already been updated. It is not possible to keep records. In addition to the case shown in Figure 5, for example, if multiple display devices are monitoring processes in real time,
If two hard copy devices are connected and each display device has a different screen and the heart copy requests are issued at the same time (i.e., multiple hard copy requests are made in the time that the hard copy device can process only one page). Even in the event that a hard copy occurs, the disadvantage is that only one hard copy can be processed.

Therefore, an object of the present invention is to provide a process monitoring and recording device that can effectively and reliably leave records in a plant where there is a demand for a large amount of monitoring and recording in a short period of time, such as during a shutdown period in a nuclear fusion device.

[Structure of the invention]

(Means for solving the problem) The state of the plant is imported into the arithmetic processing unit via the process input device, and the captured process state changes and state quantities are displayed by the arithmetic processing unit on a display device connected to the arithmetic processing unit. Process data processing means and display data creation means for processing data into displayable data; display display means for displaying the data processed by the display data creation means on a display device; and display on a hard copy device connected to the display device. hard copy means for giving a command to record the data displayed on the display device by the display means on the hard copy device; hard copy request determining means for determining whether hard copy is necessary based on the process status; The data processed by the display data creation means is stored in a display data storage device provided in the arithmetic processing unit, and whether hard copy is possible is determined based on the update speed of the display device and the recording speed of the hard copy device, which are set in advance in the arithmetic processing unit. and a display data storage means for determining the condition and activating the hard copy means if the determination is acceptable.

(Function) The present invention adds a storage device for storing display data to a conventional device consisting of a process monitoring processing device (process input device, arithmetic processing device, etc.), a display device, and a hard copy device.

In response to a hard copy request, display data is transferred to a storage device and used as a delay buffer, and a hard copy is made based on this data.Also, the large number of process state changes and state quantities that occur when operating a plant that performs intermittent operation is A large number of hard copy requests can all be processed according to the recording speed of the hard copy device.

(Embodiment) FIG. 1 shows an embodiment of the present invention, and the same parts as in FIG. 4 are given the same reference numerals. 19 is a display data storage means for storing display data and activating the hard copy means, and 20 is a display data storage device (hereinafter referred to as display memory) for storing display data. Assume that a hard copy request is issued only when a state change occurs, including a request from an operator.

The operation from capturing the plant status to displaying it on the display device 17 is the same as that of the conventional device. The hard copy request determining means 18 determines whether or not a hard copy is necessary based on the information in the process memory 14 in the same way as in the conventional apparatus, and if there is a hard copy request, the display data storing means 19 is activated. Display data creation means 15
The display data processed by and output from the display display means 16 is stored in the display memory 20, and the hard copy permission number is determined based on the display update speed, the state of the hard copy device 22, and the recording speed, and if the hard copy is possible, the hard copy is made. The means 21 is activated. Hard copy means 2
In response to the hard copy command from 1, the display data storage means 19 performs a hard copy based on the data in the display memory 20.6 The display data storage means 19 performs hard copying when a hard copy request occurs even during hard copying, that is, when hard copy cannot be activated. , transfers and stores the display data to the display memory 20. And a hard copy device! 22 is in a state where hard copy is possible, it is determined and the hard copy means is activated to record the stored data in hard copy. Display this operation Memory 2
Continue until there is no more data saved on 0. This operation flowchart is shown in Figure 2.The effect of this configuration is that display data corresponding to a large amount of hard copy requests that occur in a short period of time compared to the time required for hard copying can be displayed at a relatively high speed. By delaying it in the memory 20, recording to the low-speed hard copy device 22 can be performed without data loss, and data displayed on the display device can be displayed in real time without slowing down the update speed to match the speed of the hard copy device. It is possible to realize a device that does not lose its characteristics.

That is, the present invention is suitable for monitoring plants that operate intermittently, such as nuclear fusion devices. A process monitoring and recording device that effectively and reliably records monitoring when a large amount of status data is generated in a short period of time has been obtained.One example of this is to use a video signal as the 0 display data and a video tape as the display memory. .

In another embodiment of the present invention, two routes are set for display data to the hard copy device 1122, one from the display display means 16 and the other from the display memory 20, with a configuration similar to that shown in FIG. 1, and a switch is connected between these two routes. It is conceivable to provide 23. This is the 6 display data storage means 19 shown in FIG.
are the hard copy request occurrence status and the eight-hard copy device 22.
The switch 23 is set to perform hard copying based on the display data from the display means under normal conditions (that is, when hard copying is possible), and the hard copy means is activated. to make a hard copy. When a hard copy request occurs at a speed exceeding the speed of the hard copy device 22 (that is, when hard copy is not possible), the changeover switch 23 is set to perform hard copy using the display data in the display memory 20, and the display data is is transferred to the display memory 20.
save. If the hard copy device 22 is capable of hard copying, the hard copy means is activated to perform hard copying. Repeat this until there is no more data stored in the display memory 20.

When the data in the display memory 20 runs out, the changeover switch 23 is set to the display means side. As long as the data in the display memory 20 does not run out, the changeover switch 23 is fixed to the display memory side. The advantage of this configuration is that the display memory load is reduced.

Further, the following device can be considered with the same configuration as that shown in FIG. 3, but with the display memory 20 as a large-capacity memory (one row, magnetic disk). During normal times (while repeating intermittent operation), hard copies are made using the data displayed on the display device 17, as in the conventional device.

Data that cannot be hard-copied is retained in the display memory 20 and hard-copied using the data in the display memory 20 while the plant is stopped (that is, during a period when normal monitoring is not performed). The hard copy changeover switch 23 is on the display display means 16 side, and when there is a hard copy request, the display data storage means 19 is activated, and the display data storage means 19 is connected to the hard copy means 2.
The display data storage means 19 checks whether the display data requested for hard copy is predetermined storage data or does not require real-time monitoring (there is no need to display it on the display). Or, if hard copy is not possible and it is a record sheet, the display data can be stored in display memory 2.
When the display data storage means 19 determines that the plant is stopped and normal monitoring is no longer necessary (for example, in the middle of the night), the display data storage means 19 switches the changeover switch 23 to the display memory 20 side and stores the data in the display memory 20. The copying means 21 is activated to make a hard copy, and this is done until the data in the display memory 20 is exhausted.Thereby, the operating state can be saved and recorded by display data independently of real-time monitoring by the display. It is possible to do this.
