Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a display method for a disaster prevention system.

[Prior Art] Conventionally, the information display of this type of disaster prevention system has been performed by providing a number of display windows for each warning area as shown in Fig. 11, and illuminating the display windows when an alarm occurs; This was done by a method using a display panel using 7-segment LEDs as shown in FIG.

However, in these conventional examples, it is difficult to grasp the information at the time of alarm,
There is a problem in that the display contents are limited when grasping the daily system status.

Therefore, the present inventor filed Japanese Patent Application No. 1-44431 with kanji,
Using CRT, liquid crystal display, plasma display, etc. that can display kana, alphanumeric characters, etc. Floor Ji! We propose a display method in which lower screens are selected in order from the upper screen. [Problem to be Solved by the Invention] In this patent application No. 1-44431, as shown in FIG. 13, when displaying a screen D in a different hierarchy from a certain screen A, first the menu screen B is displayed by operating a menu key. Switch to
From the menu displayed on the menu screen, a predetermined screen D had to be selected and displayed by operating the corresponding key C, which was a time-consuming operation.

In addition, when switching from screen D to the original screen A, it was necessary to return to menu screen B using the menu key, and then select screen A from menu screen B using the corresponding key operation C to switch and display it.

Furthermore, I was simply entering a 4-digit or 10-digit password on the change table change screen, etc., but I was worried that it could be tampered with. The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a display method for a disaster prevention system that improves the operability when switching display screens and allows more rapid response to situations.

An object of the invention as set forth in claim 2 is to provide a display method for a disaster prevention system in which reliable security measures are taken to further prevent changes in setting contents due to mischief.

[Means for Solving the Problems] The present invention provides hierarchical display of each piece of information in a disaster prevention system on the screen of a display device using an image display device such as a CRT or a liquid crystal display provided in a receiver of the disaster prevention system. In addition, in the display method of the disaster prevention system that displays the relationship between the function keys related to the necessary operations on each screen and their contents, selections are displayed directly on the top screen of each hierarchy regardless of the current screen. In order to do this, a shift key is provided to switch and display the operation content of the function key, and when the shift key and the function key are operated simultaneously, the display screen is switched to a screen corresponding to the operation content of the function key. The invention according to claim 2 is characterized in that the password input is enabled only when the shift key is operated simultaneously on the password input request screen. [Operation] According to the present invention, it is possible to escape from the display of the current hierarchy and switch to the screen display of another hierarchy simply by operating the shift key and the function key at the same time.

Furthermore, since screens that require a password to be entered require the shift key to be entered, security measures against mischief are more reliable than simply entering a password, and the number of digits in the password is easier to remember. It can be set to a number. [Examples] The present invention will be explained below using examples.

1), "Abnormality" screen (E2-1), "Transfer stop J screen (E4-1)""Alarmhistory" screen (F2-3), "Current history screen (F2-5)" Since each screen relates to important information for a disaster prevention system, the display can be directly switched using the numeric keypad in addition to switching the lillFa display using the function keys F1 to F5.

In this way, the screen display is sequentially switched from the upper level to the lower level based on the hierarchical display, and the settings of the operation contents of the function keys F1 to F5 can be changed and the operation contents can be displayed on the switching screen.

By the way, when the shift key SF is operated while a predetermined screen of each layer is being displayed, the operation contents of each function key Fl to F3 and F5 will be changed to "Displayed on the Monitoring Screen (So)" as shown in Figure 9. The content of the operation is changed, and the function key F4 is assigned a "previous screen" return operation for returning to the display of the previous screen, and the content is displayed. When the operation of the shift key SF is released in this state, the operation contents corresponding to the currently displayed screen are set for the function keys F1 to F5, and the operation contents are displayed at the same time. While operating shift key SF, press function key F.
When any one of 1 to F3 and F5 is operated, it is possible to directly switch to screen B of the corresponding display hierarchy, regardless of the hierarchy of the current display screen A, as shown in FIG. Furthermore, after switching the screen, by operating the function key F4 while operating the shift key SF, it is possible to return from the currently displayed screen B to the previous screen A. [Effects of the Invention] The present invention provides hierarchical display of various pieces of information in a disaster prevention system on the screen of a display device using an image display device such as a CRT or a liquid crystal display provided in a receiver of the disaster prevention system, and This is a disaster prevention system display method that displays the relationship between the function keys related to the necessary operations on each screen and their contents, so it has a screen hierarchical structure that is very easy to remember for disaster prevention-related construction companies and maintenance companies. It has an easy-to-handle man-machine system,
Furthermore, a shift key is provided to switch and display the operation contents of the function keys in order to directly select and display them on the topmost screen of each hierarchy regardless of the current screen, and the operation of this shift key and the function keys are operated simultaneously. In particular, the display screen is switched to a screen corresponding to the operation content of the function key, so you can exit the display of the current hierarchy and switch to the screen display of another hierarchy simply by operating the shift key and operating the function key. It has the effect of being able to switch, quickly moving screens, improving operability, and being able to accommodate a wide range of users. Furthermore, since the invention as claimed in claim 2 makes password input valid only when the shift key is operated simultaneously on the password input request screen, it is a security measure against mischief, etc., compared to the case where the password is simply input. This has the effect of making it more reliable and allowing you to set the number of digits in your password to a number that is easy to remember.
