Abstract

PURPOSE:To prevent the overlook of the accident warning data of a high priority by constituting the reading means of a data buffer in a display element so as to decide the priority and to display the accident warning data high in the priority. CONSTITUTION:When the sensor of its own floor is operated, the accident warning signal is recognized by the relay 2 of its own floor to feed the accident warning information to the display device 4 and the receiver of its own floor. Detailed display information is read from a rereading table 7, stored in the buffer 8a, for instance, and displayed on a display element 10 by the use of a ROM 9. The accident warning information of the sensor of the other floor is fed to the relay 2 of that floor as the accident warning information of the other floor, recognized as the information of the other floor, stored in the buffer 8c for the other floor and simply displayed on the element 10 through the ROM 9. At the time of successively receiving the information, a priority is decided to switch and display the information of the high priority. The low priority information is only stored in the buffer 8 and not displayed. According to this constitution, the overlook of the high priority information is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an indicator for a disaster prevention system in a building having multiple floors.

[Background technology] Conventionally, indicators for disaster prevention systems in buildings with multiple floors are
When a fire or gas leak occurs, the type of alarm, location of the alarm, etc. are displayed on a display element based on the alarm data from the sensor.

Here, the alarm indications are fire on the 0th floor, fire in the basement,
There is a gas leak on the 0th floor and a fire forecast on the 0th floor. By the way, such a display is designed to display an alarm corresponding to one piece of alarm data, so when multiple alarm data are received, they are received sequentially. The alarm data is temporarily stored in a data buffer 7, and a display element displays the information, and the alarm data can be sequentially displayed by operating a display advance switch. However, in such a conventional example, the alarm data is stored in the data buffer in the order in which it is received, and unless the display advance switch is operated, the alarm data that was received first (the first report) is always displayed.
is displayed on the display element, so there were cases where alarm data with a high priority could not be recognized. In other words, even though the fire alarm data on the 0th floor is the most important for the person looking at the display, when the fire alarm data on the 0th floor is received, the fire alarm data on other floors can be detected. When the alarm data is being received, the display element displays the alarm data of the fire on other floors, and the alarm data of the fire on the 0th floor is stored in the data buffer T. Therefore, the display can be changed by operating the display advance switch 8! I didn't know Noh,
If you forget to operate the display advance switch, the priority is 0.
There was a problem in that the alarm data for fires on floors was overlooked, potentially creating a dangerous situation.

[Objective of the Invention J The present invention has been made in view of the above-mentioned points, and its object is to be able to always display alarm data with a high priority on a display element, and to display alarm data with a high priority. To provide a display device for a disaster prevention system in which alarm data is not overlooked.

[Disclosure of the Invention] (Configuration) The present invention includes a data buffer that sequentially stores alarm data from a plurality of sensors of a disaster prevention system, and a display device that displays one alarm data read out from the data buffer 7 as appropriate. In a disaster prevention system display device equipped with a display element, the priority of alarm data currently displayed on the display element and newly received alarm data is determined, and the alarm data with a higher priority is displayed on the display element. By configuring the data reading means of the data buffer 7 in such a way, the display element can always display high-priority alarm data, and a disaster prevention system in which high-priority alarm data is not overlooked can be realized. It provides an indicator.

(Example) Figures fjS1 to 2 show an example of the present invention.
The disaster prevention system includes a plurality of detectors 1 installed on each floor of a building to detect fires, gas leaks, etc., and a receiver 3 receives alarms from the detectors 1 via repeaters 2 on each floor. The alarm data is displayed on a display 4 placed on each floor.

Here, the display device 4 provided on each floor stores a signal receiving circuit 6 for receiving alarm data for the 0th floor and other floors, and detailed display data for displaying the alarm data for the 0th floor in detail. The display device 4 is composed of a reading conversion table 7 and a kanji ROM 9 for displaying the detailed display displayed on the display element 10 in kanji characters, and the detailed display data is read out from the reading conversion table 7 using the alarm data of the 0th floor. Kanji characters are displayed on the display element 10, and alarm data from other floors is simply displayed as is. Further, the data buffer 78 provided in the display 4 includes a 0th floor fire buffer r8m that sequentially stores detailed display data indicating the hot water area where the fire occurred on the 0th floor;
It is formed by a local floor buffer 7a 8b that sequentially stores detailed display data of the gas leak location on the 0th floor, and an other floor fire buffer 8c that sequentially stores alarm data indicating the hot water area where a fire occurred on other floors. Alarm data being displayed on the display element 10 (in the example, detailed display data such as fire on the 0th floor or gas leak,
Data reading means for the data buffer 8 is configured to determine the priority of the newly received alarm data (simplified display data of fires on other floors) and display the alarm data with a higher priority on the display element 10. ing. In addition, sensor 1, repeater 2,
Received! The alarm data transmitted between the 9!3 uplink display devices 4 is time-division multiplexed via a pair of signals M5. FIG. 3 is a front view showing an example of the display device 4. There is a transmitter 14 at the top that lights up a power light 11, a fire representative light 12, a gas leak representative light 13, and a transmitter light 14a, and in the center there is a liquid crystal display element that can display kanji characters in three stages. A display element 10 is arranged. Further, at the bottom are a telephone jack 15, an alarm buzzer 16, an alarm buzzer stop switch 17, and a display feed switch 18g.
8b, a fire determination switch 19 is provided.

The operation of the embodiment will be described below. Now, the repeaters 2 on each floor are constantly checking the monitoring data returned from the sensors 1 by sequentially cyclically accessing the sensors 1 using the time division multiplexed signal transmitted via signal #15. A unique address is set for each sensor 1 that detects fire or gas leak, and when accessed from repeater 2, the detection result of fire or gas leak is returned as monitoring data. In addition, the receiver 1, which manages disaster prevention information for the entire building, sequentially accesses the repeater 2 to Shark Click to return disaster prevention information for each floor, and transmits alarm data to the repeater 2 on each floor as appropriate. It has become. It goes without saying that the transmission of monitoring data and the transmission of disaster prevention information may be performed by interrupt processing.

Next, in the display device 4, the signal receiving circuit 6 receives the alarm data transmitted by time-division multiplexing from the repeater 2, as shown in FIG. 4(a).
It is designed to be displayed using the 70-chart shown in FIG.

That is, the received alarm data is first determined whether it is alarm data for the 0th floor (fire on the 0th floor, forecast on the 0th floor, gas leak on the own floor, etc.);
Fire alarm data on other floors will be sent to a branch office. Here, if the alarm data is for the 0th floor, the detailed display data corresponding to the alarm data is read out from the table 7 and the 0th floor fire buffer 8a of the data buffer r8 or the 0th floor is the sub-7 alarm. 8b. On the other hand, if it is fire alarm data on another floor, the alarm data is stored as it is in the other floor fire buffer 8c as simplified display data. The data stored in the data buffer 8 as described above is displayed on the display element 10 in a predetermined 7-ohm format.

For example, the display operation of the display device 4 located on the second floor will be concretely explained as follows. If the detector 1 installed in the second conference room of the 14th district on the 0th floor (2nd floor of the 1st building) detects a fire, the relay 2 installed on the 0th floor will immediately notify the 14th district. The alarm from detector 1 is recognized, and the type of alarm (fire on the 0th floor) and location (line number,
alarm data (for example, 1-2-14
) via the signal line 5 to the display unit 4 on the 0th floor. Reception 8!3
sent to. Display unit 4 on the second floor that received this alarm data
Now, the detailed display data (14 areas, 2nd conference room, 2nd floor of 1 building) is read out from the reading table 7 based on the alarm data of the 0th floor fire, and the 0th floor fire buffer 8 of the data buffer 8 is read out.
a, and displayed on the display element 10 using the kanji ROM 9. On the other hand, when the sensor 1 on another floor (for example, the 6th area on the 1st floor of one building) issues an alarm, the alarm data is sent to the receiver 3 via the repeater 2 on that floor, and the receiving W13 , performs display and corresponding processing based on this alarm data, and transmits this alarm data as basement alarm data (basement fire, 1-1-6) to that floor via repeater 2 on floors other than the first floor. The data is sent to display unit 4. At this time, when the display device 4 on the second floor receives alarm data from another floor, it recognizes it as alarm data from another floor and stores the data as it is in the other floor fire buffer 8c as simplified display data. A simplified display (6 areas on the 1st floor of 1 building) is performed on the display element 10 using .

Next, when alarm data is received one after another, display data corresponding to the alarm data received first is stored in the data buffer 78 and displayed on the display element 10, and then When the alarm data is received, the display data corresponding to this alarm data is stored in the data buffer y8 (each can store 20 pieces of data), and the display data corresponding to this alarm data is stored in the data buffer y8 (each can store 20 pieces of data). The priority of the alarm data received later is determined, and the display data of the alarm data with higher priority is read out from the data buffer 78 and displayed on the display element 10. In the example, the priority is set as fire on the 0th floor > gas leak on own floor > fire on the basement > fire forecast on the 0th floor, and when multiple alarm data with the same priority is received, the first report is sent. I am trying to display it. For example, if alarm data for a fire on the 0th floor, which has a high priority, is received while alarm data for a fire on another floor is being displayed on the display element 10, the display element 1
The display content of 0 can be switched to the display of alarm data for the fire on the 0th floor, which has a high priority. On the other hand, if alarm data having a lower priority than the alarm data currently being displayed is subsequently received, the alarm data is simply stored in the data buffer 8 and the display is not switched. Note that nothing is displayed on the display element 10 in an initial state where no alarm data is received.

As described above, the display element 10 always displays high-priority alarm data, and the danger of high-priority alarm data being overlooked can be avoided. It goes without saying that other display data of lower priority stored in the data buffer 8 can be sequentially displayed by operating the display advance switches 18a and 18b as in the conventional example.

Figure 5 shows an example of a display. Figure 5 (a) shows the alarm display for a fire on the 0th floor, Figure 5 (b) displays the alarm alarm for a fire on another floor, and Figure 5 (c) shows a display example.
) is an alarm display for a gas leak on the own floor, and (d) in the same figure is an alarm display for a fire forecast on the 6th floor. The display screen of the liquid crystal display element is 240×64 dots, and as shown in FIG.
It is possible to display 6 x 16 dot characters in an arrangement of 3 columns vertically and 15 characters horizontally.

Figures 7(a) and 7(b) show examples of the first stage display. Figure 7(a) shows the alarm data display, and the type of alarm (fire, gas leak, forecast) is shown on the left. is displayed, and on the right side,
The number of stored alarm data and the ranking of the data being displayed are displayed. In addition, the same figure (b) shows the data display of the reading table 7, and the type of alarm, the code of the alarm location (line number, sensor number), the rank in the table, and the number of data in the table are displayed. be done.

Figure 8 shows an example of the display on the second stage, with (a) to (
d) shows the display of alarm data for the 0th floor, and (e) to (h) of the same figure show the display of alarm data for fires on other floors above, including line numbers, floor numbers, district numbers, basements, rooftops, vertical holes, etc. The location of the alarm is displayed based on the alarm data. The detailed alarm data display on the third stage can display up to 15 characters, and the location of the fire or gas leak on the 0th floor is displayed in easy-to-understand kanji characters based on the data read from the translation table 7, and the location of the fire or gas leak on the 0th floor is displayed in easy-to-understand kanji, No display is made in the event of a fire.

It goes without saying that each display example is a display according to the situation at the site (presence or absence of a ridge, presence or absence of underground, rooftop, vertical hole, etc.).

In addition, the data in the rereading table 7 is initially set when the system is installed, and can be rewritten as appropriate if there is a change in the data contents thereafter. Only the detailed display data corresponding to the alarm data of the floor is stored, and the alarm data of other floors that do not require detailed display are displayed in a simplified manner, and the display corresponding to the alarm data is performed depending on the degree of necessity. Therefore, effective display corresponding to alarms from the sensors 1 on the 0th floor and on other floors can be performed using a small memory capacity.

[Effects of the Invention] As described above, the present invention includes a data buffer that sequentially stores alarm data from a plurality of sensors of a disaster prevention system, and displays one alarm data read out from the data buff 77 as appropriate. In a display device of a disaster prevention system equipped with a display element, the priority of alarm data currently being displayed on the display element and newly received alarm data is determined, and alarm data with a higher priority is displayed on the display element. By forming the data reading means of the data buffer in this manner, it is possible to always display alarm data with a high priority on the display element, and there is an effect that alarm data with a high priority will not be overlooked.
