[Examples] The present invention will be described below with reference to examples.

FIG. 1 shows a basic configuration of a disaster prevention system using an embodiment of the present invention. In this embodiment, a disaster prevention receiver 1 and
Data transmission / reception is performed by time division multiplex transmission via a transmission line 1 with a relay 2 connected to a fire detector 3 that generates an analog sensing output. Of the fire detectors 3 connected to... Are collected, and the detected output data are compared using a predetermined threshold value, and an alarm operation such as a fire alarm or a forecast is performed. I have. The disaster prevention receiver 1 is connected to a disaster prevention host computer 5 that receives fire information from the disaster prevention receiver 1.
Is determined, the fire information is converted into data of a predetermined format, and transmitted to the disaster prevention indicator control device 6 as an RS232C signal.

The disaster prevention display controller 6 has a function of converting the data from the disaster prevention host computer 5 into character and graphic display data to be displayed on the disaster prevention display 4.
A function for transmitting the converted display data as an RS232C signal is further provided, and a keyboard 8 for inputting data and a display 7 such as a plasma display for displaying data are provided.

Meanwhile disaster display 4 ... are each dispersed is connected to a plurality of signal lines LI ₁ ..., disaster display 4 ... of the number to be connected LI ₁ ... to each signal line and each fixed number, signal lines LI ₁ giving an address separately from disaster display 4 ... connected to the up disaster display 4 connected to the signal line LI _n in ascending order.

Upon receiving the fire information from the disaster prevention host computer 5, the disaster prevention indicator control device 6 converts the display data based on the fire information into a format corresponding to a predetermined communication format, and the attached communication CPU card 9, RS232C through 9
To the RS232C / current converter 10
The signal is further converted to a 20 mA current loop signal by the 32C / current converter 10 and transmitted to the disaster prevention indicators 4 connected to the signal line LI _{1. The} disaster prevention indicators 4 correspond to fire information. The display corresponding to the display data is performed.

 Reference numeral 11 denotes a power supply unit of the RS232C / current converter 10.

Here, each of the disaster prevention displays 4 corresponds to a disaster prevention display device of the present invention, and these disaster prevention displays 4 include a display 12 such as a CRT, a keyboard 13, and the like as shown in FIG.
The control unit 14 includes a control unit 14 for data transfer and screen control, and a light pen or mouse 15 as a point device.

On the other hand, the disaster prevention receiver 1 has a storage unit for storing history data of the sensing output from the fire detectors 3... There are the following three types of history data stored in this storage unit. First, only for the fire sensor 3 registered in advance, the period history data stored while updating the sensing output for a certain period in the past from the current time at a predetermined sampling period, such as one week before the current time, Current history data that is collected and stored while updating the sensing output of the past three minutes (for example, three minutes) from the current point of time (for example, three minutes) at a predetermined sampling period, and the fire sensor 3 that has issued a fire There is alarm history data in which the sensing output of the past several minutes (for example, 3 minutes) from the alarm time is stored.

Next, the display operation of the history data on the disaster prevention display 4 as the disaster prevention display device of the present invention will be described.

First, the operation will be described with reference to the flowchart shown in FIG. 3. In the state shown in FIG. 4 in which the operation screen is displayed on the display 16 of the disaster prevention display 4, the setting content fields of the function keys displayed below the screen are shown. When the coordinates of the function key corresponding to the setting content field displayed as "Analog" are hit by the mouse 15 (or operated by the keyboard 13), the control unit 14 displays the display screen of the display 16 in FIG. The screen is switched to a selection screen for selecting the fire detector 3 for displaying the history data.

In this screen, a message requesting selection with the mouse 15 for the symbol mark M of the fire detector shown on the map of the displayed alert area is displayed at the lower left of the screen.

Here, when the coordinates of the symbol mark M are hit and input by the mouse 15, the control unit 14 changes the color of the symbol mark M to another color to indicate that the symbol mark M has been selected, and also displays the selection of the fire detector 3. The command to request the history data transfer is
The information is transmitted to the disaster prevention receiver 1 through the RS232C / current converter 10, the communication CPU board 9, the disaster prevention indicator control device 6, and the disaster prevention host computer 5. By this request command, the disaster prevention receiver 1
Then, if the requested period history data or alarm history data of the target fire detector 3 is being sampled, the data indicating that the sampling is being performed is transferred to the disaster prevention display 4 in a direction opposite to the above command.

The control unit 14 of the disaster prevention display 4 displays a message indicating that the period history is being sampled or the alert history is being sampled on the screen of the display 16 based on the transfer data.

If the selected fire detector 3 does not have the alarm history and the period history sampled, the data to that effect is transferred from the disaster prevention receiver 1, and the control unit 14 of the disaster prevention display 4 transmits the data. And a message indicating that the history is not sampled is displayed. In this case, the current value may be transferred from the disaster prevention receiver 1 and displayed.

By hitting the coordinates of the function key in the setting field of the "report history" or the "period history" corresponding to a certain history during the sampling, or operating the function key itself The control unit 14 issues a data transfer request command to the RS232C / current converter 1
0, transmit to the disaster prevention receiver 1 through the communication CPU board 9, the disaster prevention indicator control device 6, and the disaster prevention host computer 5.

The disaster prevention receiver 1 reads out the alarm history data or the period history data of the fire detector 3 requested based on the data transfer request command from the storage unit, and reads the disaster prevention indicator in the opposite direction to the transfer of the command. Transfer to 4.

Based on the transferred history data, the control unit 14 of the disaster prevention display 4 performs a multi-window W operation as shown in FIG.
To display the history in a graphical representation. It is needless to say that the multi-window display is not performed even when hitting the coordinates of the function key of the history that has not been sampled or operating the function key itself.

After selecting the fire detectors 3, if the hit of the function key corresponding to the "current history" in the setting content column on the screen of FIG. 5 or the operation of the function key itself is performed, the fire detectors 3 are selected. Can be transferred from the disaster prevention receiver 1 to the disaster prevention display 4 in the same manner as the above-described history data transfer.
Displays the current state history in a multi-window W in a graph expression in the same manner as each history described above.

A multi-window W displaying a graph in this way
Can be erased by hitting the coordinates of the function key corresponding to "cancel" in the setting contents column of FIG. 6 or operating the function key itself. The selection of the fire detector 3 can be canceled by hitting the coordinates of the function key corresponding to "clear" in the setting content column on the screen of FIG. 5 or operating the function key itself.

By the way, as described above, the collection of the period history data is intended for the fire sensors 3 registered in advance.
This registration is performed by hitting the coordinates of the function key corresponding to “Registration” in the setting content column or operating the function key itself on the operation screen shown in FIG.
14 switches the screen of the display 16 to a registration screen as shown in FIG. 7 based on this hit or operation. The fire sensor 3 to be registered is selected by hitting the symbol mark M of the predetermined fire sensor 3 on the map displayed on this screen with a mouse. In response to this selection, the control unit 14 changes the color of the symbol mark M of the fire detector 3 to indicate that it has been selected.

To cancel this selection, hit the coordinates of the function key corresponding to "Clear" in the setting content column on the screen of FIG. 7 or operate the function key itself. Now, after selecting, hit or operate the coordinates of the function key corresponding to "Setting" in the setting content column,
The control unit 14 transmits the selected data and the registration command of the selected fire detector 3 to the disaster prevention receiver 1 through the RS232C / current converter 10, the communication CPU board 9, the disaster prevention indicator control device 6, and the disaster prevention host computer 5. become.

Upon receiving the selection data and the registration command as described above, the disaster prevention receiver 1 starts sampling the period history data of the fire detector 3.

When data indicating that this sampling has been started is returned from the disaster prevention receiver 1 to the disaster prevention display 4, the control unit 14 changes the shape of the symbol mark M of the fire detector 3 from, for example, from ● to ■ as shown in FIG. This is changed to indicate that the registration has been completed and the sampling of the period history data has been disclosed.

Next, when canceling the registration, the registration screen shown in FIG. 7 is displayed, and after hitting the symbol mark M of the target fire detector 3, the function key corresponding to “delete” in the setting content column is pressed. By hitting the coordinates or operating the function key itself, it is possible to cancel the registration by sending a cancel command to the disaster prevention receiver 1 together with the selected data of the selected fire detector 3. In this case as well, the symbol mark M of the fire detector 3 is discolored at the time of selection by the operation of the control unit 14 as in the case of registration, and the shape is changed at the time of release to display the respective states.

 The symbol mark M 'in each screen indicates a smoke prevention device.
