The processing device 20 includes a screen interface setting unit 21, a screen interface control unit 22, a data management unit 23, an event processing unit 24, and a screen switching unit 25. The screen interface database 30 includes an identifier for identifying a place where an event has occurred, a screen for displaying a symbol, a symbol display content such as a shape, a position and a size of the symbol, an event type such as a color of the symbol and blinking. The associated symbol display type and the like are stored.

When the user updates the symbol on the screen of the display device 10 or its background screen, the screen switching unit 25 selects from the screen interface database 30 at the request of the user via the screen interface setting unit 21 or the like. A required screen is selected and displayed on the display device 10 through the screen interface setting unit 21. The screen interface setting unit 21 prompts the user to select the existing symbol display contents or create and input new symbol display contents, and further inputs the identifier of the place where the event is generated and the symbol display type. Let The data management unit 23 changes the contents of the screen interface database 4 with the input contents.

During operation of the application, the event processing unit 24 receives from the application program body 40 the display type transmitted by the event occurrence place as an event condition associated with the event when the event occurs, and if necessary, the place concerned. The identifier is added and transmitted to the screen interface control unit 22. The screen interface control unit 22 receives the event condition transmitted from the event processing unit 24, adds the identifier of the screen currently being displayed to the event condition as a symbol search condition, and transmits the event condition to the data management unit 23. The data management unit 23 searches the screen interface database 30 and extracts the display content and display type of the symbol that matches the search condition. The screen interface control unit 22 receives it and displays the symbol on the currently displayed screen selected by the user by the screen switching unit 25 first. It should be noted that when a screen switching request is issued from the application program body side during operation of this application, the screen switching unit 25 receives the request through the event processing unit 24 and the screen interface control unit 22, and the screen switching unit 25 receives the request from the screen interface database 30. A screen is selected and displayed on the display device 10 via the screen interface control unit 22.

Next, the processing flow of FIG. 1 will be described in detail, divided into the case where the application program is operated and the case where the user changes the display of the symbols on the screen and the background screen thereof.

FIG. 2 is a process flow diagram when operating an application program. When an event occurs, the application program 40 transmits the symbol display type for notifying the event to the event processing unit 6 (step 101). Event processing unit 2
In 4, the event occurrence location is added to the symbol display type and the event information is transmitted to the screen interface control unit 22 (step 102). If the event processing unit 24 does not have a means for detecting the event occurrence place, the application program 40 notifies the event processing unit 24 of the event occurrence place. The screen interface control unit 23 receives the event information (step 103). In general, the symbol display type is determined by the combination of the event occurrence place or the screen on which the symbol is displayed. Therefore, the screen interface control unit 22 identifies the identifier of the screen on which the symbol is displayed,
The data management unit 23 is used as a search condition for specifying the symbol display content in the screen interface database 30.
(Step 104). The data management unit 23
The symbol display content that matches this search condition is retrieved from the screen interface database 30, the symbol display content is converted into a displayable symbol format, and the symbol display content is returned to the screen interface control unit 22 (steps 105, 1).
06). The screen interface control unit 22 displays the required symbol on the display device 10 such as a display board or a CRT (step 107).

FIG. 3 is a processing flow chart when the user changes the display of the symbols on the screen and the background screen.
The screen interface setting unit 21 displays the screen interface setting screen on the display device 10 and asks the user to first select from the screens prepared in the screen interface database 30 or to have the user newly create and input the screen. Select a screen for symbol display (step 201), and then screen interface database 3
The symbol to be displayed is selected by selecting it from the screen prepared during 0 or by newly creating and inputting it (step 202). Then, the screen interface setting unit 21 automatically acquires the identification number of the selected screen and the symbol display contents (coordinates, shape, size) of the symbol as basic information (step 203), and further, the selected. The place where the event corresponding to the symbol occurs and the symbol display type are input as meaning information (step 204). The data management unit 23 receives the basic information and the meaning information from the screen interface 21 and stores them in the screen interface database 30 (step 205).

As described above, since one combination of the screen for symbol display, the place where an event occurs, and the symbol display type corresponds to one arbitrary symbol display content, the symbol display can be freely changed. Note that the method of selecting symbols and screens, the method of newly creating them, and the method of accumulating them in the database are not directly related to the present invention, and therefore will not be described in detail here. Further, the user customization function of FIG.
By performing the exclusive control of, it is possible to start the application program at any timing even while the application program is running.

Concretely, a monitoring system to which the present invention is applied will be described with reference to FIG. This monitoring system is A
In the system that monitors the failure of the system 51, the B system 52, and the C system 53, it is assumed that the locations of the respective systems are different and an event indicating the failure occurs from these systems. The occurrence information of this event is
It is assumed that an application program of the monitoring system body 50 inputs the processing system 20 of the display system of the present invention. At the time of inputting an event, the processor 20 displays a symbol whose color is changed depending on the degree of failure near the location of each system shown on the map. Here, for the sake of simplicity, it is assumed that the normal symbol is displayed as a white symbol and the failure symbol is displayed as a black symbol.

First, the user customization function for creating or updating the screens and symbols used in this system will be described. A map used for the screen is created by OCR or the like and stored in the screen interface database 30 as image data. In addition, a wide area map and a plurality of detailed maps are prepared for each purpose. The positions of the systems 51, 52 and 53 are written as A, B and C on these maps. The screen interface setting unit 21 and the data management unit 23 store the screen and symbol information in the screen interface database 30. In this system, the name of the system where the failure occurred (hereinafter "location")
And the type of failure (hereinafter referred to as “type”) are used as meaning information. The user inputs this meaning information from the window on the screen interface setting screen displayed on the display device by the screen interface setting unit 21. For the map information, the screen interface setting unit 21 requests the screen switching unit 25 to read the existing map information from the screen interface database 30 and display it on the screen interface setting screen. User select. Similarly, the symbol information is also set by reading it from the screen interface database 30 and displaying it on the screen interface setting screen, and selecting the symbol from the user using the mouse or the like and moving it to a desired position. The input basic information and meaning information are automatically stored in the screen interface database 23 by the data management unit 23. These pieces of information may be exchanged with preset information. As for the screen and the symbol, if the screen interface setting unit 21 prepares from the beginning,
You may use it. In the example of FIG. 4, the place is A,
Type 4, "A" for failure display of A system 51,
"□" for failure display of B system 52, C system 53
It means that "○" is set for the failure display of.

Next, the flow of processing when this system is operated will be described. First, the user requests the screen interface control unit 22 to display a necessary map as a display screen on the display device. In the example of FIG. 4, the second map is the display screen. In this system, all monitored systems transfer an event of “normal” (type 4) to the event processing unit 24 in advance at the start of operation and display a blank symbol at all positions. And It is assumed that failure type 5 has occurred as an event from the B system 52. Here, the failure type 5 is “display of black color”. In the event processing section 24, this "B,
The information of 5 "is transferred to the screen interface control unit 22. In the screen interface control unit 22, the number 2 of the map screen currently displayed is added to this information and the search condition of the symbol display content in the screen interface database 30 is added. “B, 5, 2” is transferred to the data management unit 23. The data management unit 23 searches the screen interface database 30 with this search condition and selects a location where the search condition shown in FIG. The management unit 23 creates a symbol "filling a square" to be displayed based on the size "8" of the search result, the shape "square", and the type "5", and the screen interface control unit 2 together with the coordinates (40, 400).
Return to 2. In the screen interface control unit 22, the symbol of "filling in squares" is set to coordinates (40, 40).
It is displayed in 0). As a result, the symbol □ corresponding to the display of B is notified as to the failure and changes as shown in FIG.

Note that the user requests the screen interface control section 21 to switch the screen of the necessary map at the necessary occasion.
