[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant data printing apparatus in an industrial plant such as a nuclear power plant.

[0002]

2. Description of the Related Art Not only in nuclear power plants but also in industrial plants, in order to keep a history of plant states that change from moment to moment and a history of operator operations, these histories are printed and stored in a printer. Further, the printing of data necessary for the operator's driving operation is also carried out, and these printings have various contents depending on the purpose, and are roughly classified as follows.

(1) Plant status change history The history of plant status such as start / stop of the pump and opening / closing of the valve of the pipe is printed, and the time of status change, equipment name, equipment status, etc. are printed.

(2) Operator operation history The operator operation history for the plant monitoring device such as the change of the calculation constant of the plant monitoring device and the request for the calculation processing by the operator's request is printed. Is printed.

(3) Plant log data A plurality of data such as plant data and calculation data based on the plant data are printed in a fixed time unit in order to manage the history of the operating state of the plant. Print multiple sheets at regular intervals. Further, there are a plurality of types of plant log data depending on the purpose or the like.

(4) Operator request data printing The data required for the plant operation is printed according to the operator's request. A list of plant status data and a calculation result in the plant monitoring device are printed. The various types of printing described above are carried out, and the printing device is determined according to the purpose.

The above (1) plant state change history,
(2) The operator operation history is a print of almost one line for each state change / operation, and it is necessary for the operator to immediately see the output data for plant operation and monitoring. In this case, if LBP is used as the printing device,
If the data for one LBP sheet is not collected, the data is not printed, so the operator cannot immediately see the printed contents. For this reason, a typewriter (to be referred to as a TW hereinafter) capable of printing on a line-by-line basis is used.

(3) The plant log data can be printed even by TW, but it is output in sheet units because a plurality of data is printed, and in many cases it is output in a fixed format table format, and printing is fast. The LBP is used because it has a high degree of freedom in data layout and is easy to see.

(4) For the operator request data printing, the printing data is required at the operator's hand, and it is convenient to use the LBP which can print on a sheet unit basis and which can take out the printed sheet. In addition, a large amount of printing requests may occur, and high-speed L
BP is required.

As described above, since the printing device is installed depending on the purpose of printing contents, generally, as shown in FIG.
Two types of printers, P and TW, were installed and used properly for each function. Further, in the plant data printing apparatus, data loss is not allowed in order to manage the operation history of the plant, and usually two or more printing apparatuses of the same type are installed to enable backup when the printing apparatus fails.

[0011]

The plant data printing device described above requires two types, TW and LBP, depending on the usage pattern. Considering the backup of each device, two types x 2 units for a total of 4 units. Printer is required. On the other hand, the monitoring control room of the plant in which the printer is installed has a limited space, and it has been required to make the installation space of the printer as small as possible.

However, at present, four printers are required, and due to the structure of the TW, the data printing noise is large and it is necessary to put it in a soundproof structure desk to eliminate the printing noise, and the printer installation space is further increased. It was big. Further, when the number of printers is reduced as much as possible due to the problem of the installation space as described above, there is a problem that print data having a plurality of functions are mixed in one printer, the data is difficult to see, and management is difficult.

The present invention has been made to solve the above problems, and provides a plant data printing apparatus capable of reducing the number of printers, eliminating the soundproofing machine, and reducing the installation space. The purpose is to do.

The operation of this embodiment will be described. Function A
The output type addition unit 2 adds print information for line output or sheet output to the print data output from 1 (second embodiment). The print information added here is fixed for each function. If the print data of the function output to the TW in the past is line output, if it is the print data of the function output to the LBP, the print information of the sheet output. Is added.

Similarly, print information is added to the print output data from the function B3 by the output type adding section b4.
The print data a to which the print information is added is input to the data storage / extraction unit 5. The structure of the print data a to which the print information is added is shown in FIG.

FIG. 2 is a flow chart showing the processing contents of the data storage / extraction unit 5. FIG. 3 shows the data structure of the output data storage unit 7. The processing contents of the data storage / extraction unit 5 will be described below with reference to FIG. Initially,
To initialize the output data storage unit 7, the number of data lines is set to "0" (step S1).

Next, when print data is input (step S2), it is judged from the print information of the print data whether sheet output or line output (step S3). If a sheet output request is made, the print data is sent to the LBP6. Output (step S4) and input the next print data.

If it is a line output request, the print data is stored in the output data storage unit 7 (step S5) and the number of data lines is counted up (step S6). Next, it is judged from the number of data lines whether the stored print data has been stored by the number of lines of one sheet of LBP (step S7), 1
If the number of sheets is not enough, the next print data is input (step S2).

When the saved print data for one LBP sheet is reached, the saved print data is output to the LBP 6 (step S8), the number of data lines is cleared to "0" (step S1), and the next print data is saved. input. By the above processing, the print data output to the conventional LBP is output to the LBP 6 as it is and printed, and the print data output to the conventional TW is stored in the output data storage unit 7 as L.
After storing one BP sheet, it is output to LBP6 and printed.

Next, the display data creation unit 8 first takes out the number of data lines in the output data storage unit 7, takes out the print data for the number of lines, changes the display data, and displays the print data on the display unit 9. . As a result, LBP6

FIG. 4 is a block diagram of the third embodiment of the present invention. In FIG. 4, reference numeral 100 denotes a plant monitoring device, which includes a function A1, an output type addition unit 2, an output data distribution unit 21, a data transmission unit 22, a server abnormality determination unit 26, and a data transmission unit b27.

A print server 101 includes a data receiving unit 23, a data storing / extracting unit 5, and a print data output unit 2
4, the output data storage unit 7 and the display data creation unit 8, the print data output unit 24 is connected to the LBP 6, and the display data creation unit 8 is connected to the display 9.

The print server 102 has the same structure as the print server 101. However, the print data output unit b30 is connected to the LBPb31, and the display data creation unit b33 is connected to the display device b34.

The operation of this embodiment will be described. First,
The normal operation when the LBP and the print server are normal will be described. The print output data from the function A1 is input to the output type addition unit 2, and the print data a to which the print information of line output or sheet output is added is output to the output data distribution unit 21.

If the output data distribution unit 21 is line output print data, the print data is stored in both the data transmission unit 22 and the data transmission unit 27 in order to store the output data in both the print server 101 and the print server b102. Distribute.

If it is sheet output print data, it is not necessary to save the print data in the print server, so the print data is output to either one of the data transmission units. Here, normally, all print data is LB.
When printing is performed on the P6 side, data b with a print index added to the line output print data to the data transmission unit 22 is output, and printing without a print index added to the line output print data to the data transmission unit b27. Print data a to which only information is added is output.

The structure of the data b added with the print index is shown in FIG.
Shown in. The print data for sheet output is output only to the data transmission unit 22 side. The data transmission unit 22 inputs the distributed print data and sends the data to the print server 101. Similarly, the data transmission unit b27 inputs the distributed print data and sends the data to the print server b102. The data receiving unit 23 in the print server 101 receives the transmitted data and outputs the data to the data storage / extraction unit 5.

FIG. 5 is a flow chart showing the processing contents of the data storage / extraction unit 5. 1 is different from FIG. 1 in that when the page output data is included in the line output data after the print information is determined, the part for performing the output processing to the LBP and the number of data lines are L.
This is to add a part for determining whether or not to output print data to the LBP depending on the presence / absence of the print index before the data is output to the LBP when one sheet of BP is reached.

The data storage / extraction unit 5 stores print data in the case of a line output request and outputs print data in the case of a sheet output request, similarly to FIG. 1, regardless of the presence or absence of a print index. In the data storage / extraction unit 5 of FIG. 4, when the print data for line output becomes one sheet of LBP, if the last print data has a print index, the print data is output, and if there is no print index, the print data is output. throw away.

In the normal state, since the print data on the print server 101 side has a print index, the line output print data is output without being discarded. The print data output unit 24 inputs the data from the data storage / extraction unit 5 to input LBP6.
Output data to. The operation of the display data creation unit 8 and the display 9 is the same as in FIG.

On the other hand, the internal structure of the print server 102 is the same as that of the print server 101, but the print server b 102
Since the print data on the side has no print index, the print data is discarded when one LBP sheet is collected.

Next, the operation when there is an abnormality in the LBP 6 and the print server 101 will be described. The abnormality of the LBP 6 is notified to the server abnormality determination unit 26 detected by the print data output unit 24. In addition, an abnormality of the print server 101 is detected by the data transmission unit 22 and notified to the server abnormality determination unit 26. The server abnormality determination unit 26 notifies the output data distribution unit 21 as an abnormality on the print server 101 side by any of the above abnormality notifications.

In response to this abnormality notification, the output data distribution unit 21 adds the print index normally added to the line output print data to the data transmission unit 22 to the line output print data to the data transmission unit b27. Further, the print data output of the sheet output request is output from the data transmitting unit 22 side to the data transmitting unit b27 side. After that, printing is performed on the LBPb 31 on the print server 102 side as in the normal operation.

When the LBP 6 and the print server 101 are restored to normal, the page break data with the print index is output from the output data distributor 21 to the data transmitter b27.
When page break data is input to the data saving / extracting unit b29 in the print server b102, even if the print data saved in the output data storage unit b32 is less than one LBP sheet, it is output.

When the print server 101 is abnormal, the print data is stored only on the print server b102 side. Therefore, after the print data stored in the print server b102 is printed, the print data on the print server 101 side is printed. By switching so that the print index is added to, the loss of printing of the line print data is eliminated.

Next, the operation when an abnormality occurs in the plant monitoring apparatus 100 will be described. In this case, the data reception unit 23 detects a data reception abnormality. Data receiver
When the data reception abnormality is detected at 23, the page break data with the print index is output to the data storage / extraction unit 5. The data storage / extraction unit 5 outputs the data of the output data storage unit 7 by the same processing as the operation when the LBP and the print server are recovered from the failure, and eliminates the printing loss of the line print data.

As described above, according to the embodiment shown in FIG.
Even if a failure occurs in any of the P, print server, or plant monitoring device, the print data processed by the plant monitoring device is printed without LBP printing, and the LBP is functionally operated in the same manner as TW. As a printing device for a plant monitoring device such as a power plant where the loss of print data is not allowed, all printing devices can be LBP.

If it is not a page break, the function type is extracted from the print data (step S74), the print data is stored in the storage area for each function type of the output data storage unit 7 (step S75), and the number of data lines is counted up. Yes (step S76). The print data saved next is L
It is judged from the number of data lines whether or not the number of lines of one sheet of BP has been saved (step S77), and if it is less than one sheet, the next print data is input (step S2).

Saved print data is LB for each function type.
When one sheet of P has been printed, if the last data has a print index (step S78), the stored print data is output to the print data output unit 24 (step S7).
9) If there is no print index, print data will not be output.

Next, the number of data lines is cleared to "0" (step S791), and the next print data is input (step S2). With the above processing, print data can be stored and retrieved for each function type, and printing can be performed with sheets separated for each function type.

Next, the operation of the display data switching / creating section 42 will be described. In the display data switching / creating unit 42, the display requesting function type from the display switching unit 43 is input, the print data corresponding to the requested function type number is taken out from the output data storage unit 7, converted into the display data and displayed.

Output to the container 9.

Also, since a large amount of print data is stored for each function type, the display switch 43 is provided with a page forward / backward switch, and print data to be displayed within each function type by the page forward / backward operation. To be able to select. As a result, all print data for each function can be displayed. The print server b102 also operates similarly to the print server 101. As described above, according to the present embodiment shown in FIG. 9, the print sheets can be collectively output for each function, and the management of the print sheets becomes easy.

Next, a modified example will be described. 4, FIG. 6, and FIG. 9 have been described as a configuration in which two print servers are provided for one plant monitoring device. However, if the plant monitoring devices have a multiplex structure and the number corresponds to the print server, the device can be simplified by providing each plant monitoring device with a print server function.

Further, FIGS. 4, 6 and 9 have been described as a duplex configuration using two print servers to distribute print data to each. However, the configuration is not limited to this, and the print data may be distributed with three or more print servers. In this case, the degree of freedom of the entire structure is large and it can be obtained.

Further, in FIG. 4, FIG. 6 and FIG. 9, the print server and the LBP are in a one-to-one relationship to form two sets.
An LBP switching device is installed between the print server and the LBP, and the print server and the LBP are configured in a 2 to 2 configuration to provide the LB.
When the P failure occurs, the print server side can switch the LBP to allow the plant monitoring apparatus side to judge only the failure of the print server.

As described above, according to the present invention, the contents previously printed by the typewriter for the purpose of printing can be output by the laser beam printer, and the number of printers can be reduced and the soundproofing machine can be deleted. In addition, the printer installation space can be reduced. In addition, by enabling separate printing for each functional unit, the data can be easily viewed,
Easy to manage.
