BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a fire receiver R according to the present invention.
It is a block diagram which shows the structure of E1.

The fire receiver RE1 is a fire receiver for monitoring and controlling the entire fire alarm system including a plurality of fire detectors, and includes a CPU (central processor unit) 10 and
ROM 20, RAM 30, LCD 42, display driver 50, first line controller LC1, second line controller LC2, third line controller LC3, fourth line controller L
C4 and signal line L to configure fire alarm equipment
Although a plurality of fire detectors are connected via 1, L2, L3, L4, the detectors S11, S21, S31, S are shown in the drawing.
41 is shown.

The fire receiver RE1 further has an input control unit 60 and an output control unit 70, and outputs emergency switches SW1 and SW2 and alarm sounds provided at necessary portions via the input line Li and the output line Lo. Acoustic devices B1 and B2 for ringing are connected.

The emergency switches SW1 and SW2 are push-button switches and are installed side by side between the input lines Li composed of two electric wires so that either of the emergency switches SW1 and SW2 can be operated. Then, the input line Li conducts as an emergency signal. The input control unit 60 can detect the emergency signal by monitoring whether the input line Li is in the conductive state and detecting the conductive state. This emergency signal is the departure command signal (General Al
arm), in which case a 7-min-1 long-departure warning must be sounded. Such emergency switches SW1 and SW2 are not provided in each part of the ship, and the authority to issue a leaving command is limited to a predetermined crew member. Therefore, the emergency switches SW1 and SW2 are provided in a limited place. It is provided only in the necessary places such as the captain's room, and specifically only one place is required.

The acoustic devices B1 and B2 are bells, sirens, or the like, and their ringing is controlled by a power source supplied through the output line Lo. Therefore, the output control unit 70
Controls the timing of supplying power to the output line Lo continuously or intermittently, and controls other timings, so that the sound devices B1 and B2 ring in the same alarm pattern. That is, the output control unit 7
If 0 continuously supplies power to the output line Lo, a continuous sound is emitted, and if the output control unit 70 intermittently supplies power to the output line Lo, an intermittent sound is emitted and an output control unit is output. 70
If the power is supplied to the output line Lo for 7 shorts and 1 long, the departure warning is sounded with 7 shorts and 1 long tone. These acoustic devices B1 and B2 are appropriately arranged in a necessary amount so that each part of the ship can perform sounding with a predetermined sound pressure.

The line control units LC1 to LC4 are connected to a plurality of fire detectors via the signal lines L1 to L4 which are also power lines and signal lines, and the reception of fire signals from the fire detectors is It may be either so-called P type or R type, but in the case of R type, an individual address is given to the fire detector connected to each signal line and the address is received at the same time as the fire signal. The location of the fire can be specified by. Such a fire detector is S1
1 to S41 are provided in each room such as a passenger room and an engine room in a ship so that they can respond to a fire.
Further, on the signal lines L1 to L4, it is possible to install a controlled device such as a smoke prevention device or a fire extinguisher other than the fire detector as a terminal device, and by specifying an address and outputting a start signal, it is possible to specify. The controlled device can be activated.

The operation of such a fire receiver RE1 will be described.

First, when a fire occurs, the detection level of any of the plurality of fire detectors S11 to S41 for detecting smoke or heat rises, and the line controller LC1 is connected via the signal lines L1 to L4. ~ LC4 receives a high detection level as the status of each fire detector. Then, when it is determined that the fire state is exceeded by exceeding the predetermined reference value, the line control units LC1 to LC4 transmit a fire signal to the CPU 10.

When the CPU 10 receives the fire signal, the ROM
According to the program in 20, the display drive unit 50 causes the LCD 42 to display a fire, and at the same time, transmits a fire signal to the output control unit 70. Upon receiving this fire signal, the output control unit 70 supplies power for the fire alarm to the output line Lo, and causes each of the acoustic devices B11 and B12 such as a bell to sound the fire alarm.

Here, either a continuous sound or an intermittent sound is used for ringing the fire alarm. In the case of a continuous sound, the output control unit 70 continuously supplies power to the output line Lo to generate the intermittent sound. In this case, it is supplied intermittently at a predetermined interval. The sounding of the fire alarm may be selected according to the owner of the ship and the area where it is used, and is not particularly limited to one.
The output control unit 70 only needs to specify what kind of ringing method should be used in the case of a fire alarm.

Next, when a ship leaving warning is required, when an authorized captain of the crew understands the emergency and decides to evacuate the passengers and crew, the emergency switch near The SW1 and SW2 are operated to cause the input control unit 60 to detect an emergency signal via the input line Li. Then, the input control unit 60 which has detected the emergency signal transmits the emergency signal to the CPU 10.

The CPU 10, which has received the emergency signal, follows the program stored in the ROM 20 in the same manner as in the case of a fire.
At the same time that the display drive unit 50 causes D42 to perform an emergency display, an emergency signal is transmitted to the output control unit. Upon receiving this emergency signal, the output control unit 70 supplies power to the output line Lo for the departure warning, and outputs the sound devices B11 and B1 such as bells.
2. Make the departure warning sound.

Here, the sounding of the leaving warning is set to 7
It is necessary to ring the short 1st long sound, and the output control unit 70 supplies the output line Lo with a power source adapted to the 7 short 1st long sound.

[0023] In the case of such a fire, the case where the ship leaving warning is required, the cases have been described individually, but both cases may be duplicated. For example, in the case where a ship leaving warning is issued due to the spread of a fire after the occurrence of a fire, the output control unit 70
Priority is given to the departure warning. That is, the output control unit 70
A fire alarm is issued by receiving a fire signal from the PU 10, and if a ship leaving signal is received from the CPU 10 during this fire alarm, the ringing method is switched to the ship leaving warning. Further, the output control unit 70 issues a ship leaving warning by receiving an emergency signal from the CPU 10. However, even if a fire signal is received from the CPU 10 during this ship leaving warning, the ringing method is not switched to the fire warning.

In order to enable such alarm operation,
In the output control unit 70 in this embodiment, a plurality of ringing patterns for the output line Lo are set. That is, pattern 1 is a continuous sound, pattern 2 is a first intermittent sound that is turned on and off every second, and pattern 3 is turned on for 3 seconds and is 2
The second intermittent sound that turns off for a second, as pattern 4, is composed of 7 short sounds that are turned on and off every second, and is shown in Fig. 2 as a departure warning sound that combines 5 seconds of sound and a long sound of 2 seconds of stop. A predetermined ringing can be performed by setting the timing of such a repeating unit and selecting it.

The selection of the ringing pattern for the signal received from the CPU 10 is set in the output control unit 70 in advance, and the ringing pattern for the fire signal is specified by setting the ringing pattern for the fire signal. Therefore, if the continuous sound is set, the output control unit 70 controls the ringing of the continuous sound in response to the fire signal from the CPU 10, and if the first intermittent sound is set, the fire signal from the CPU 10 is set. To control the sounding of intermittent sound that turns on and off every second.

The selection of the ringing pattern does not need to be preset in the output control section 70, and the CPU 10 may output a signal designating the ringing pattern as a fire signal.
Further, although the ringing for the emergency signal is determined to be the leaving warning sound, it may be designated in the output control unit 70, or the leaving warning sound can be designated by the CPU 10 by designating the ringing pattern like the fire signal. May be specified.

The output control unit 70 may be allowed to set a ringing pattern as shown in FIG.
In FIG. 2, (1) is a continuous sound, (2) is a first continuous sound,
(3) shows a second intermittent sound, and (4) shows one cycle of the leaving warning sound, and a predetermined warning sound is emitted by repeating this one cycle. That is, the first intermittent sound is ON / OFF every 1 second, but can be expressed as ON 1 second OFF 1 second, and similarly, the second step continuous sound is ON 3 seconds OFF 2 seconds. It is possible to freely form an intermittent sound pattern by combining them. For example, on 2 seconds off 2 seconds or on 2 seconds off 1
A ringing pattern of seconds is also possible. And on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 5 seconds off 2 seconds By doing so, it is possible to represent the departure warning sound of 7 short 1 long sounds. On 1 second off 1 second on 1 second off 1 second on 1 second off 2 seconds on 1 second off 1 second on 1
Second off 1 second on 1 second off 2 seconds on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off 1 second on 1 second off If it is 2 seconds, it will be a so-called 3/3/7 beat.

In the above-described embodiment, the fire receiver RE1 can cope with a fire alarm ringing when a fire occurs and a ship leaving alarm ringing in an emergency. Although the form of simultaneous ringing by B11 and B12 is adopted, for example, the fire receiver RE1 and the acoustic devices B11 and B12 of the other parts may be separately controllable as the main sound and the district sound. May use an audio repeater as a terminal device via the signal lines L1 to L4 to ring the audio device. In this case, it goes without saying that the acoustic repeater has the same function as the output control unit 70 of this embodiment.
If the main sound provided in the fire receiver RE1 can cover the entire area of the inside of the ship, the district sound is unnecessary.

It is also possible to provide a plurality of output control units 70 and divide the sound device into regions for each output line Lo to perform the segmental ringing.
