The numbers in the time digits are changed to selected numbers, and when the time set is finally selected, the time displayed in the set time display section is set in the clock circuit, allowing the correct time to be set or corrected. It is.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention.

First, the configuration will be described. Reference numeral 1 denotes a CRT display device, and in the case of fire alarm equipment, for example, it is installed on a console panel installed in a central monitoring room. 2 is a clock circuit that outputs time information to be displayed on the CRT display device 1;
It outputs not only minute time data, but also year, month, and day data. The time data output from this clock circuit 2 is displayed on the CRT screen 1a regardless of the display state of the monitoring information on the CRT screen 1a.
It is displayed on the time display section A in the upper right corner of the screen 1a.

Next, a circuit section for setting or correcting time data displayed on the CRT screen 1a will be explained.

3 is a light pen, and the light pen 3 is placed at a predetermined position of the image displayed on the CRT screen 1a.
When pressed, position information is transmitted by the switching operation of the built-in optical switch that receives light from the display screen 1a. The output of the light pen 3 is input to the light pen position calculation circuit 4, and the light pen position calculation circuit 4 calculates the position of the CRT screen 1a on which the light pen 3 is pressed based on the timing of the switch output of the light pen 3 in response to the sweep signal of the CRT screen 1a. , the input information selected by the light pen 3 is identified, and various control signals are output.

Here, on the display screen 1a of the CRT display device 1 shown in FIG. 1, a time adjustment screen is displayed when the time adjustment mode is selected by operating the light pen 3.

Display of this time adjustment screen is performed by the time adjustment screen display control circuit 5. That is, when the light pen 3 presses the time correction mode mark displayed on the display screen in the steady monitoring state,
A display command signal is given from the light pen position calculation circuit 4 to the time correction screen display control circuit 5, and the time correction screen display control circuit 5 reads out the correction screen information stored as memory information and displays it as shown in the figure.
A time adjustment screen is displayed on the CRT display device 1.

The contents of this time adjustment screen are first displayed on display screen 1a.
A time display part A is provided in the upper right corner of the display screen 1a to display the time of the clock circuit 2 as it is, and the time to be set in the clock circuit 2 for setting and correction is displayed in the upper part from the center to the left side of the display screen 1a. A set time display section B is provided, and below this set time display section B is provided a list of selection numbers C used for setting or correcting the time, and furthermore, in the lower right corner, a table for setting the corrected time in the clock circuit is provided. A set position D is used for setting the time, and a return position E is provided for returning the time correction screen to the normal monitoring screen without setting the time to the clock circuit 2.

FIG. 2 shows in more detail the correction screen of the CRT display device 1 in the embodiment shown in FIG. and the time are displayed, and the set time display section B shows the year, month, and time displayed on the time display section A.
The day and time are displayed as they are, and the contents of each numerical digit, ie, the codes indicating the year, month, day, hour, and minute, are also displayed. Further, in the selection number list C below the set time display section B, the numbers that can be taken by the time digit are individually listed for each time digit in the set time display section B.

On the other hand, at the set position D, a display "SET" for instructing the clock circuit 2 of the set time display section B is displayed, and at the return position E, the time correction mode is canceled and the normal processing routine resumes. The message "RETURN" is displayed.

Referring again to FIG. 1, a change display control circuit 6 is provided to set or correct the time display using the correction screen displayed on the CRT display device 1 by the time correction screen display control circuit 5. The time setting or correction by the change display control circuit 6 is started by switching to the time correction screen by selecting the time correction mode with the light pen 3, and the selected number list C on the time correction screen shown in FIG. Press the light pen against any number corresponding to the time digit to be corrected, and use the light pen 3 to select the number of the time digit corresponding to the set time display section B based on the position detection by the light pen 3. The number will be changed to the selected number. That is, the result of setting or correcting the time using the light pen 3 is to change the number on the set time display section B.

Selected number list C using a light pen like this
After the time has been corrected on the set time display section B, the corrected time for the clock circuit 2 is set by pressing the set position D on the time correction screen with the light pen 3. Based on the position detection by the light pen 3 at position D, the time information displayed on the set time display section B is set in the clock circuit 2 by the clock set circuit 7, and at the same time, the selection of the time correction mode is canceled and the normal mode is set. Returning to the monitoring screen, since the clock circuit 2 has been corrected by the clock set circuit 7, the corrected time of the clock circuit 2 will be displayed on the display screen after the correction mode is released.

Next, the processing operation of time setting or correction according to the embodiment of FIG. 1 will be explained with reference to the flowcharts of FIGS. 3 and 4.

Figure 3 shows a general flowchart equipped with the time adjustment function of the present invention. In normal monitoring mode, when you press the display area for time adjustment mode on the screen with the light pen 3, you can select the time adjustment mode. is judged in judgment block 10, and the time setting processing routine in block 11 is executed.

FIG. 4 is a flowchart showing this time setting processing routine.The time setting processing is started by selecting the time correction mode with the light pen 3, and first, in block 12, the current time of the clock circuit 2 is read and corrected. Time numerals are written into the image information from the memory corresponding to the time display section A and the set time display section B on the screen, and in block 13 the time correction screen shown in FIG. 2 is displayed on the CRT. The next judgment block 14 monitors the switch-on state by pressing the light pen to a predetermined position on the display screen, and when the light pen is turned on, the process advances to the next block 15 to check the light pen position on the CRT. Calculate.

Now, in order to correct the time in the time display, suppose that the light pen 3 is pressed against an arbitrary number in the list of selected numbers C corresponding to the hour digit. This is determined as the pen position, and in block 19 the number selected with the light pen is set in the corresponding time digit of the set time display section B. In the next block 20, the clock information is read out in the same manner as in block 12, and the current time is displayed on the time display section A, and the determination block 14 is again executed.
Return to

Thereafter, in the same manner, every time a number is selected for each time digit in the selection number list C, block 15 is selected.
The processes from 20 to 20 are repeated, and as a result, the set time display section B displays the number of the time changed for time setting or correction.

When the number change in the set time display section B based on the number selection from the selected number list C is completed, the process proceeds from the determination block 16 to the block 21 by pressing the set position D with a light pen.
The changed time numerals displayed on the set time display section B are set in the clock circuit, and in block 22 the corrected screen is erased and the normal time display is returned. In addition, if the return position E is pressed without pressing the set position D after changing the time on the set time display section B, the process advances from determination block 17 to block 22.
The correction screen is erased and the original time display is returned to without setting the display time of the set time display section B in the clock circuit.

In this way, when setting or correcting the time using the time setting device of the present invention, it is only necessary to change the number of the time digits that require correction, so the operation for changing the time is simple and can be done in a short time. The time can be quickly adjusted without making a mistake.

In addition, although the above embodiment takes as an example the selection of the time correction mode using a light pen and the correction of the time display using the correction screen, in other embodiments, the time may be corrected using a marker that moves with the shift key on the keyboard. may be carried out in the same manner, and a resistive sheet consisting of a transparent thin conductive film pasted on a resistive film made by pasting a transparent resistive film on a transparent glass surface may be provided on a display for detecting analog coordinates X and Y. A transparent finger touch input device may be used to select the time adjustment mode and adjust the time. Further, in the above embodiment, a CRT display device is used as an example of the display device, but the present invention is not limited to this, and the same operation can be performed using a liquid crystal display device.

(Effect of the invention) As explained above, according to the invention, when the time adjustment mode is selected with a light pen etc.
Switch the CRT to the time adjustment screen, and this time adjustment screen includes a set time display section that displays the time to be set in the clock circuit for adjustment, and a selection number list that individually lists possible numbers for each time digit. If you select the time digit that requires correction in the selection digit list on the correction screen with a light pen, etc., the corresponding time digit in the set time display will be changed to the selected digit, and the final If you perform the time set operation, the changed time digits displayed on the set time display will be set in the clock circuit. Now you only need to change the numbers in the time digits that you need, making operations for setting or correcting the time much easier than in the past when all the time digits had to be entered. Since only the required time digits need to be changed, errors can be reduced compared to conventional devices in which all the time digits are entered.
