Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a disaster prevention display device used for centrally monitoring local disaster prevention information such as fires, and in particular, to display terminals where disasters have occurred based on the disaster prevention information. The present invention relates to a disaster prevention display device that displays map information.

(Prior art) Conventionally, in the case of a centralized disaster monitoring system that centrally monitors disaster information such as fires on a regional basis, message data indicating the district, address, name, etc. of the terminal is prepared for each subscriber terminal. When receiving a message, the message data corresponding to the receiving terminal is read out from memory and displayed as an image on a display device such as a CTR, so that the terminal where the disaster occurred can be accurately identified.

(Problem to be Solved by the Invention) However, in such conventional disaster display devices, messages are displayed on each terminal, so when the number of receiving terminals increases, the message is displayed by the location, terminal name, and disaster type. There is a problem that it becomes difficult to understand the correspondence relationship between the two. On the other hand, it is possible to make the judgment easier to some extent by displaying the alarm location on a map and combining it with the message display. However, when the number of receiving terminals increases, the correspondence between the map display and the message display It is difficult to clarify
Furthermore, since map data must be prepared for each terminal, the memory capacity becomes large and the cost of the device also increases.

(Means for Solving the Problems) The present invention has been made in view of such conventional problems, and provides a map that can appropriately judge the situation when disaster information is received from a plurality of terminals. The object of the present invention is to provide a disaster prevention display device which can display messages and which requires a small memory capacity, and is constructed as follows.

That is, in a disaster prevention display device that receives disaster information from terminals at a center and displays the disaster information and the occurrence terminal on a display device, map data for each terminal group and message data for each terminal are stored in the storage section. When the first disaster report is received, the corresponding map data and message data are read out from the storage unit and displayed, and the disaster terminal on the display map is displayed in the first hue, for example, red, and when the second and subsequent disaster reports are received, , performs display control (display control unit) to display the disaster terminal of the display map in a second hue different from the first hue, for example yellow, and furthermore, presses the send button when the second or higher report is received. If you operate it, the second
A display switching unit that switches one of the hue display terminals to the first hue display, erases the message of the first hue terminal, and reads the message data of the hue switching terminal from the storage unit and displays it. ).

(Example) Figure 1 is the basic configuration of the present invention (claim correspondence diagram)
FIG.

First, to explain the configuration, 1 is a disaster receiving section, and as will be clarified in later examples, CATV
Identifies and receives abnormalities such as fire, theft, and gas leaks from the terminal information received using the system's transmission line, etc., and receives the first report, second report, ..., nth report in the order in which disaster information is received. gives the received information.

Reference numeral 2 denotes a storage unit in which map data and message data used for the disaster prevention display control of the present invention are stored in advance, and the map data is created for each group, with a plurality of terminals divided by district as one group. Map data is stored, and message data stores the location, name, name, telephone number, etc. of each terminal, and the message data also includes the type of disaster identified and received by the disaster receiving unit 1,
For example, message data such as fire, theft, gas leak, etc. is also included.

3 is a display control unit, to which received information from the disaster receiving unit 1 is given, and from the disaster receiving unit 1 to the first
When a disaster alert is received, the corresponding map data and message data are read out from the storage unit 2 and displayed on the display unit 4 as shown in FIG. 2, for example. In displaying map data based on reception of this first report, for example, as shown in FIG. 2, a first hue predetermining the location of disaster terminal A in the first report,
For example, display in red. In addition, the display control unit 3
For disaster reception after the second report (however, for the same terminal group), the disaster terminal on the map displayed on the display section 4 is different from the first hue, that is, red, displayed for the disaster terminal in the first report. second hue,
For example, display in yellow. That is, in the display map based on the reception of the first disaster report shown in FIG. 2, if the second report of disaster information from another terminal included in the same display map is received, disaster terminal B
As shown in , if the disaster terminal A in the first report is in a different color than the disaster terminal A in the first report, for example, the disaster terminal A in the first report is red, the disaster terminal B in the second report is displayed in yellow. Note that message data is not displayed for disaster terminal B in the second report, and the message data for disaster terminal A in the first report is still displayed.

Referring again to FIG. 1, reference numeral 5 denotes a display switching section, which switches the display on the display section 4 based on the ON operation of the feed button 6. This switching function by the display switching unit 5 is such that when the forwarding button 6 is operated in the reception display state of the second and subsequent reports, for example the reception display state shown in FIG. The disaster terminal B for the second report is switched to the first hue display, that is, the red color display that is displayed for the disaster terminal A for the first report, and the second hue is displayed for the disaster terminal A for the first report. That is, the display is switched to yellow.
At the same time, the alarm message of disaster terminal A of the first alarm displayed at the bottom of the display screen is erased, and the display of the second alarm is changed from the second hue to the first hue, that is, from yellow to red. Message data corresponding to disaster terminal B is read from storage section 2 and displayed on display section 4.

FIG. 3 shows the center equipment of a centralized disaster prevention monitoring system to which the disaster prevention display device of the present invention shown in FIG. The transmission line that connects the modem 8 and the terminal is the transmission line in the CATV system.
A CATV line (coaxial cable) 9 is used.
When a terminal receives a call from the center side consisting of the communication CPU 7 and modem 8, when the call code matches the address code assigned to itself, the terminal determines that the call is its own, and detects the call at this time. Disaster information such as fire, theft, gas leak, etc. is sent back to the center as response information. This response information is demodulated by the modem 8, the data content is identified by the communication CPU 7, and then provided as received data to the display control CPU 10. This CPU 10 for display control executes control of the display control section 3 and display switching section 5 shown in FIG. 1 by program control. Reference numeral 11 denotes a memory in which map data for each terminal group divided in advance and message data for each terminal are stored. Also, 6 is the forwarding button,
Instructs the CPU 10 to change the display of the second and subsequent reports. 12 is a CRT serving as a display section, which displays map data and message data in color.

Next, display control according to the present invention using the device configuration shown in FIG. 1 will be explained with reference to the flowchart shown in FIG. 4.

First, in the normal monitoring state, as is clear from the system configuration diagram in FIG. 3, intensive monitoring of terminal information is performed by calls from the center using a polling method. If a disaster such as a fire, gas leak, or theft occurs in a specific terminal in this state, the disaster reception unit 1 of the center performs disaster reception as shown in block 13 of FIG.
The first received data is obtained. Next, in the determination block 14, it is checked whether or not it is the first notification. At this time, since it is the first disaster notification, the process goes to block 15, and the display control section 3 selects the first notification.
The map data and message data corresponding to the designated disaster terminal are read out from the storage unit 2 and displayed on the display unit 4.
For example, it is displayed as shown in FIG. At the same time, the position of the first disaster terminal A on the displayed map is displayed in a first hue, for example, red, so that the operator can see the position of the disaster terminal on the map at a glance by looking at the displayed map. . Of course, by looking at the alarm message at the bottom of the screen, the user can immediately know that the type of disaster is fire, and the address, name, and telephone number of the first disaster terminal A.
When the display process shown in block 15 is completed, the process returns to block 13 and preparations are made for receiving the second disaster report.

Next, if the second disaster report is received by the disaster receiving unit 1, since it is the second report, the process proceeds from determination block 14 to block 16, and the terminal for the first disaster report currently displayed is displayed. When the disaster terminal is included in the same group as the second disaster terminal on the display map, for example disaster terminal B shown in Figure 2, the second hue different from the first hue (red), for example yellow, indicates the disaster. Display terminal B in color.

Subsequently, if you want to know the contents of the second disaster terminal, all you have to do is turn on the forward button 6. This on operation of the forward button 6 is determined by the determination block 17, and in block 18, the display switching unit 5 selects the The hue of the disaster terminal B in the second report shown in FIG. 2 is switched to the first hue, that is, the yellow display is switched to the red display. Along with this hue change, the first
Regarding disaster terminal A, the red color will be changed to yellow. In addition, the message of the disaster terminal A of the first report that was displayed before the operation of the forwarding button 6 is deleted, and the message data corresponding to the disaster terminal B of the second report whose hue has been changed from yellow to red. is read from the storage unit 2 and the message display is switched.

Note that the display switching in block 18 based on the determination of whether the forward button 6 is turned on as shown in the flowchart of FIG. Hue switching and message switching may be performed by interrupt processing based on an operation.

Furthermore, when the forward button 6 is operated and multiple disaster reports of the second or higher order are being received, the hue and message are switched in accordance with the order of alerts each time the forward button 6 is turned on. . Of course,
The hue and message display may also be changed by specifying a specific disaster terminal using a keyboard or the like.

(Effects of the Invention) As explained above, according to the present invention, map data for each terminal group and message data for each terminal are stored in the storage unit, and upon reception of the first disaster report, the map data for each terminal group and the message data for each terminal are stored in the storage unit. In addition to reading out and displaying the corresponding map data and message data, the disaster terminal on the display map is displayed in the first color, for example, red, and for receiving the second and subsequent disaster reports, the disaster terminal on the display map is displayed in the first color. The second color is different from the hue of
When the display is controlled to be displayed in color, for example yellow, and the send button is operated while the second or higher report is being received, one of the second hue display terminals is displayed.
At the same time, the hue of the first hue terminal that had been displayed until then is switched to the second hue display, and the message of this terminal is erased and switched to the first hue display. Since the display is switched to read the terminal's message data from the memory and display it, even if the second or subsequent disaster report is received for multiple terminals in a group included in the same map, the map on the display screen will not change. Since different colors are displayed on the same map without any changes, it is possible to easily judge the relationship between disaster terminals and the surrounding situation and take appropriate measures. For subsequent disaster terminals, operating the forwarding button will switch from the second hue to the first hue and display the message data of the terminal whose hue was changed at the same time. You can easily understand the contents without confusing them.

Moreover, since map data need only be prepared for each of a plurality of terminals divided by area, the storage capacity of map data can be significantly reduced compared to the case where map data is provided for each terminal, and the device cost can be reduced.
