Description

TECHNICAL FIELD The present invention relates to a disaster prevention system for a building having a plurality of floors.

[Background Art] Conventionally, a disaster prevention system for a building having a plurality of floors has a plurality of detectors for detecting fires, gas leaks, etc. arranged on each floor of the building, and the alarms of the detectors are transmitted via a relay on each floor. The reception data is received by the receiver, and the alarm data is displayed on the display device provided on each floor. In this case, when a fire or gas leak occurs, the detailed data of the alarm (type of alarm, location of alarm, etc.) will be displayed on the display, but the detailed data will be displayed. In order to do so, a memory (for example, EEPROM) for storing this is required, so that it is possible to store a large number of detailed data corresponding to the notification of the sensor of the entire building with a limited capacity of memory. I can't
Detailed data was to be displayed in response to the notification of the detector only on the floor where the indicator was installed. However, if the alarm data of the other floor is not displayed, there is a case where an appropriate treatment corresponding to the alarm of the sensor of the other floor cannot be performed. Therefore, it is conceivable to simply display the alarm data of other floors on the display, but even if the same alarm data is displayed on the same floor, the displayed contents will be different on the other floors. It is necessary to change the format of the alert data to be transmitted, the display method must be changed, the load of data processing on the receiver will be significantly increased, and the data transmission will be crowded, so that quick error notification can be performed. There was a problem of disappearing.

[Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to provide an effective display corresponding to the alarms of the sensors on the floor and the other floor with a small-capacity memory. It is to provide a disaster prevention system that can be performed by using, and can display quickly.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention, in which a plurality of detectors 1 for detecting fire, gas leakage, etc. are arranged on each floor of a building and In the disaster prevention system in which the information is received by the receiver 3 via the repeater 2 on each floor, and the alarm data is displayed on the display 4 arranged on each floor, the alarm data of the own floor and other floors Signal receiving circuit 6, a reading table 7 for storing detailed display data for displaying the alarm data of the own floor in detail, and a kanji ROM 9 for displaying the detailed display on the display element 10 in kanji. The display device 4 is configured with and the detailed display data is read from the reading table 7 with the alarm data of the own floor and displayed in Kanji on the display element 10, while the alarm data of the other floor is simply displayed as it is. It is a thing. In addition, the data buffer 8 provided in the display 4 sequentially stores the detailed display data indicating the fire occurrence place on the own floor and the detailed display data indicating the gas leak occurrence place on the own floor in order. The self-floor gas buffer 8b and the other-floor fire buffer 8c that sequentially stores the alarm data indicating the fire occurrence location on the other floor. Further, the alarm data transmitted between the sensor 1 and the repeater 2 is time-division-multiplexed transmitted through the pair of signal lines 5, and is transmitted between the repeater 2 and the receiver 3 and the display 4. The data to be transmitted is time-division-multiplexed and transmitted through a pair of transmission / reception signal lines 5. FIG. 3 is a front view showing an example of the display 4, with a power lamp 11 and a fire representative at the top. A lamp 12, a gas leak representative lamp 13 and a transmitter lamp 14 are provided, and a display element 10 composed of a liquid crystal display element capable of displaying Chinese characters in three stages is arranged in the central portion. At the bottom, phone jack 15, alarm buzzer 16,
Alarm buzzer stop switch 17, display feed switches 18a, 18

The operation of the embodiment will be described below. Now, the repeater 2 on each floor constantly cyclically accesses the sensor 1 by the time division multiplex signal transmitted through the signal line 5 and constantly checks the monitoring data returned from the sensor 1. A unique address is set to each of the detectors 1 for detecting a fire or a gas leak, and when accessed by the repeater 2, the detection result of the fire or the gas leak is returned as monitoring data. Further, the receiver 1 managing disaster prevention information of the entire building sequentially cyclically accesses the relay device 2 to return the disaster prevention information of each floor, and at the same time, transmits the alarm data to the relay device 2 of each floor appropriately. 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, as shown in the flow chart of FIG. 4, the signal reception circuit 6 receives the alarm data transmitted from the repeater 2 in a time division multiplex and displays it. That is, the received alarm data is the alarm data of the first floor (first floor fire, first floor forecast, first floor gas leak, etc.).
Or, it is classified as fire alarm data on another floor. Here, when the alarm data is for the own floor, the detailed display data corresponding to the alarm data is read from the replacement table 7 and stored in the local fire buffer 8a or the local gas buffer 8b of the data buffer 8. Remember. On the other hand, if it is the fire alarm data on the other floor, the alarm data is stored in the fire buffer 8c on the other floor as the simplified display data as it is. The data stored in the data buffer 8 as described above is appropriately displayed on the display element 10 in a predetermined format.

For example, the display operation of the display unit 4 arranged on the second floor will be specifically described as follows. Now, my floor (1
If the detector 1 installed in the second meeting room in the 14th district on the 2nd floor of the building detects a fire, the detector 2 in the 14th district is immediately activated by the repeater 2 installed in the first floor. Information is recognized,
Notification data (for example, 1-2-14) indicating the type of notification (fire on the first floor) and the location of the notification (line number, detector number) is received via the signal line 5 by the display 4 on the own floor and received. Sent to machine 3. On the display 4 on the second floor that received this alert data,
The detailed display data stored in the replacement table 7 in association with each alert data is searched. That is, in the above example, the detailed display data stored corresponding to the data 1-2-14 is retrieved from the replacement table 7 and read.
This detailed display data consists of a code string of display characters,
1-2-14 consists of a code string corresponding to the character string (1st building, 2nd floor, 14 district, 2nd conference room). This data is temporarily stored in the fire buffer 8a on the floor of the data buffer 8, and each code string is stored. The character data corresponding to is read from the Kanji ROM 9 which is a character generator and displayed at the display position of the display 4. On the other hand, when the sensor 1 on the other floor (for example, the 1st floor, 1st floor and 6 districts) issues a report, the report data is sent to the receiver 3 via the relay 2 on that floor, and the receiver 3 Then, display and corresponding processing are performed based on this alarm data, and this alarm data is used as alarm data on other floors (fire on other floors, 1-1-6) via the repeater 2 other than the first floor. Send it to the display 4 on that floor.
At this time, when the alarm data of the other floor is received, the display device 4 of the second floor recognizes it as the alarm data of the other floor and stores the data as it is as simplified display data in the fire buffer 8c of the other floor. Is used to display a simple display on the display device 10 (1 area, 1st floor, 6 areas).

When the alert data is received one after another, the display data corresponding to each alert data is sequentially stored in the data buffer 8, and the detailed display data for the earliest alert is displayed on the display element 10. The other detailed display data stored in the data buffer 8 can be sequentially displayed by operating the display feed switches 18a and 18b.

Fig. 5 shows a display example. Fig. 5 (a) shows the alarm display of the fire on the first floor, Fig. 5 (b) shows the alarm display of the fire on the other floor, and Fig. 5 (e) shows the gas leak of the own floor. Warning display, (d) of the figure is a warning display of the fire forecast of the floor. The display screen of the liquid crystal display element is 240 × 64 dots, and as shown in FIG.
Characters of × 16 dots can be displayed in an array of 3 columns vertically and 15 characters horizontally.

FIGS. 7 (a) and 7 (b) show a display example of the first row.
The figure (a) shows the alarm data display. The type of alarm (fire, gas leak, forecast) is displayed on the left side, and the number of stored alarm data and the data being displayed are displayed on the right side. The ranking is displayed. Further, FIG. 7B shows the data display of the replacement table 7, and displays 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. To be done.
