DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a message display device that displays the status of monitored equipment as a message on a display screen.

[Technical background of the invention and its problems] Fig. 1 shows an example of the system configuration of a conventional message display device using a plasma display device (hereinafter referred to as PDS) as a display screen, and Fig. 2 shows an example of the system configuration of a conventional message display device using a plasma display device (hereinafter referred to as PDS) as a display screen. , shows an example of a message screen of a conventional PDS.

In FIG. 1, 1 is a PDS, an input section 4a for mydriasis,
Based on the signals from the measurement input section 4b and the control (state) human power section 4C, data such as failure characters stored in the display memory 3 is displayed based on commands from the driver 2. −
Each of the above input sections 4a.

4b and 4c are respectively corresponding failure input points 5a.

Measurement input point 51. , has a human effort point 5C for control (state). Reference numeral 6 denotes a switching input unit for N1 measurement and control, which has a visual measurement switching switch f-6A and a control switching switch 6e, and selectively switches the display content of PDsl to either measurement At or control At. 1 is a numeric keypad operation section, which is used for inputting the device number of the device to be controlled, etc.

In the above configuration, when a failure is to be displayed first, a failure signal is input from the failure input point 5a to the driver 2- through the failure input section 41L. Next, the failure character corresponding to the failure manual point 5a is read out from the display memory 3 and output to PDsl. The displayed content of this (I) is shown in the failure message screen 8 in FIG. Explain in detail.

For measurement display, first press the n1 usage selector switch 6.
Select a, and then press !I' using the numeric keypad operation section 7.
1llllll Input the device number corresponding to the target device as a mnemonic, and input that device number to the driver 2-\. The driver 2 inputs analog data from the measurement input point 5b corresponding to the device number via the measurement input section 4b. Read the measurement character for the device number from the display memory 3. Finally, the analog data and measurement characters are combined using driver 2, and P
Display on DSJ. The display contents in this case are shown in lateral measurement message picture 109 of FIG.

In the case of control display, first press the control changeover switch 6b'
5c is selected, and then the device number is entered in mnemonic form on the numeric keypad operation section 7, and the device number is given to the driver 2. The driver 2 inputs control data through the control input section 4c from the control input point 5c corresponding to the device number, and determines whether the selected device 75<01lj is OFF based on the control data. Also, the display memory 3 is read out and the control character corresponding to the device number is read out. Finally, combine all the control characters and the ON or OFF state characters of the device to P p
Display on S1. The control message screen in this case is shown in control message screen 10 in FIG.

Conventionally, in the above-mentioned error message display device, priority was given to the failure screen, so even if a visual measurement or control screen was being displayed, if a failure signal was received, the screen would automatically switch to the mydriatic screen. . Also, even if you want to view the measurement and control screens at the same time, the PI) S7 can display only one of them, so you can switch between the measurement and control screens 'f-'f.
I had to select r:j1 directly and switch the PDSl screen.

For example, if you want to turn on one control point and see how much surge voltage is applied to the control point, or
If you want to see how long it takes for a steady voltage to be applied, it is better for control purposes to view the measurement and control screens at the same time. However, in the past, after turning on a control point on the control screen, you had to switch to the measurement screen and view the analog data of the control point, resulting in poor coordination.
Well, since a screen changeover switch is required, driver 2
Noft Square was becoming more complicated.

[Purpose of the invention]

An object of the present invention is to divide the display screen into different types of messages, such as fault display, visual measurement/control display, etc., and to display various types of messages such as measurement/control display, fault display, calendar, etc. on one screen.

This is a display board that clearly indicates the display items of 2 on stamps, etc.

Furthermore, if nothing is input from the mode selection switch input section 13, nothing is displayed on the control/measurement message screen 11, so the display area of the failure message screen 8 is expanded to the X shown in FIG. 0 In order to perform such display control, the driver 2 shown in FIG. 3 has a program area 51, a message area 52 . It has a data area of 53°, 54, etc. Here, the program area 51 has a control program section 51a for performing overall control and a second program section 51b for modifying the calendar and displaying output. A message area of multiple lines (8 lines in this case) corresponds to the display lines of the PDS1 screen. Divided into 52a to 52h. Of these, the first and second lines 52a and 52b of the message area are used for the failure message screen. Also, the third to seventh lines 52C to 52g of the message area are for mode selection. It is used for control and for the message screen 11 when there is input from the SWITCH BOOK human power department 3. If there is no input from the mode selection switch input section 13, it is used for the failure message screen 8. The 8th line 52h of the message area is used for the calendar message screen 12.
Below 0, describe the means for dividing the PDS screen and displaying each message.

In FIG. 3, in the failure message screen 8 (XIA), a failure signal is input to the PDS driver 2 from the failure input point 5 &ρ) through the failure input section 4a.
The DS display memory 3 reads the fault character corresponding to the fault input point 5a and outputs it to the fault message screen 8 shown in FIG. 4 of the PDSJ.In other words, when a fault signal is input, the mode selection switch input The input force is determined in the section 13, and if there is an input, the second line 52 of the force message area 62 shown in FIG.
The fault message data (occurrence time, fault character, "Koshiyou" character) is stored in "b" and displayed on line 802 of the PDSJ fault message screen. Here, if the fault IF# force (°C occurs continuously, the first failure is as described above e), it is stored and displayed in the 2tth message area 52b, but if the second failure signal is input. 1
, copy the first failure message gator to the first line 621L. In addition, if there is no input to the mode selection switch input section 13, a failure signal is input, and the seventh line 52g of the message area 52 shown in FIG. 5 corresponds to the failure message screen 8 shown in FIG. Store it with the failure message data and display it on the 7th line of the failure message screen 8 of PDS, J. ○If failures occur consecutively and C/j occurs, then i, 7J (1) failure number. -L noho, r
, it is stored in the message area 52g on the 7th line and displayed [However, if the second failure signal is input, the first failure message data is copied to the 6th line g21.0 In other words, r4''G Figure 7 As shown in the flowchart 1-2, if there is a failure, first the input from the mode selection switch/input section 13 is determined, and the input power is determined.
If so, the 2nd line of PDSJ will be displayed. If it is, then the data in the 2nd line 52b of the message area will be copied to the 1st line 52., and the 2nd line will be displayed. Stores new fault message data.

Then, the first and second lines of the message area are output to the PDS1 and displayed. In this way, when failures occur continuously, each time a new failure input is input, it is copied from the second line of the message area to the first line and displayed sequentially. In addition, if there is no input to the mode selection switch input section 13, the PDS
It is determined whether or not the seventh line of I is displayed, and if it is displayed, the data of the second line 52b of the message area is transferred to the first line 52a, and the data of the third line 52c is transferred to the second line 52 of fc.
b, the data in the 4th line 52d is in the 3rd line 52c, the data in the 5th line 52e is in the 4th line 52d, the data in the 6th line 52f is in the 5th line 52e, and the data in the 7th line s2g is in the 6th line. Line 5
2f, and store new failure message data in the seventh line 52g. Then, the first to seventh lines of the message area are output to the PDSI and displayed. If a failure occurs continuously in this manner, each new failure input is copied to the message area above the area and displayed in sequence. The time displayed on the failure message screen 8 as failure message data uses the time created for the calendar message screen as described later, and is stored at the time the failure signal is input to the driver 2, and is stored when the failure signal is input to the driver 2. It is output to the message screen 8 at the same time as the failure character.

Regarding the measurement/control message screen 1), the mode to be displayed on the mode selection switches 13a and 13b shown in FIG. 3 is selected. For example, control mode selection switch 1
, qa, and the measurement mode selection switch 13b to send the selection signal to the mode selection switch - manual section 13.
When input j from

is stored in the fourth line 526 of the message area 52.

Then, the data stored in the third line 52c to the fourth line 52d is output to T'1)Sf. Next, enter the device number as a mnemonic into the PD8 driver 2 from the numeric keypad operation section 7 shown in FIG.
Store in line 52r. Next, input analog data via the open side manual i4b using the measuring manual power point 5b corresponding to the device number, and send this analog data to the fifth line 52E to the seventh line 52G of the message area 52. Store r. Then, control data is inputted from the control input point 5C corresponding to the device number via the control input section 4C, and this control data is stored in the third row 52 of the message area 52. Finally, message area 52
The third line 52c to the seventh line 52G are output to the PDSJ.

As a result, as shown in FIG. 4, a control/measurement screen 11 is created on the PDSL. Of course, mode selection switch 1
It is also possible to select either the control mode or the measurement mode by the selection operations 3a and 13b and display it alone, as shown in the flowchart of FIG.

On the calendar message screen, it says September.

Day. Create the day of the week at 6:01 in the software of the driver 2° using the data tables 53 and 54 shown in FIG.
It is stored in line 1 and output to the calendar message screen 12 of PDSJ. Here, time. The minutes are created by counting clock pulses of a constant frequency obtained from a power supply, etc. In this case, after a long period of time, for example one day, there may be an error between the normal time and the normal time due to fluctuations in the power supply frequency, etc. arise. Therefore, it is necessary to prepare data to correct this error in advance. It is stored in the minute correction data areas 53I, 53j, and at the regular correction time (usually midnight), it is stored in the hour 0 minute data areas 53d, 53e. Add the corrected data,
The time is corrected using a predetermined program.

Also, year. Month. Day. The day of the week is created based on the year and month.

Day. This is calculated by adding the number of days up to the present day to the day of the week (usually the start date of operation). Month. Regarding days, calculations are performed by combining the number of days of each month stored in the data table 54 against the number of days added up to now, and the result is the year. Month. Store in the day's data area. Regarding the days of the week, numbers are set in advance for each day of the week. For example, Sunday is "l", Monday is "2"
”...Set a number such as “7” for Saturday. Then, the number corresponding to the day of the week of the reference day is added to the number of rc days up to the present, for example, if the reference date is Monday, "
Add 2'' and divide this by the number of days in a week, 7.

If the resulting remainder is 13'', Tuesday is created and stored in the day of the week data area 53k. See you next year.

Month. If you want to correct the date, enter the Eri correction data on numeric keypad 7 and set it to October. Date correction data area 531
．． I put it in 53g and 53h and put this in March. Day data areas 53a, 53b.

Modifications are made by storing the data in 53c.

In addition to the above-mentioned failure message, the failure message screen 8
The time displayed in ``C'' is 0 when created as described above.
Use minute data. That is, at the time when the fault signal is input. All you have to do is take out the contents of the data area for 20 minutes and store it in the second line of the message area 52 as described above. In the above embodiment, the calendar message screen 12 is provided in the PDSL, but this is not necessarily provided. may be omitted in some cases.

〔Effect of the invention〕

As described above, according to the present invention, the display screen is divided into different types of messages, such as failure messages, control/measurement messages, etc., and each of these messages can be displayed in parallel, which makes it possible to display different types of messages. As such, inputting a failure message will not prevent other messages being displayed from being displayed. In addition, if the display screen for control/measurement messages is not used, the display area for failure messages will be expanded, so when displaying failure messages only on the 1st and 2nd lines, the error message information will also be displayed. Easy to read on screen. Furthermore, by simply inputting the device of the compatible equipment using mnemonic, you can see both the measurement display and control display screens. Therefore, the device is turned on.

Since the OFF state and analog data can be viewed without switching the screen as in the conventional case, the instantaneous value of the analog data when the device changes from the OFF state to the ON state can also be read. Therefore, the coordination is better than when switching between screens in the past. Further, since the screen switching switch is not required, the driver software is very advantageous because the software required for screen switching can be reduced.
