DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention monitoring device which alerts an emergency such as fire in an apartment house by voice.

[0002]

2. Description of the Related Art In general, a warning of an emergency such as a fire is performed by sounding a bell. However, in apartment buildings such as condominiums, even if a bell is provided in the hallway, etc., the sound of doors and walls is excellent, and the sound of the bell may not be heard sufficiently indoors. There has been proposed a disaster prevention monitoring device that issues a warning by a voice message via the Internet.

[0003] As this kind of voice alarm device, for example, Japanese Patent Application Laid-Open No.
As disclosed in Japanese Patent Application Laid-Open No. 2-35597, a warning device using a speaker of a door phone handset as a warning message with a voice message as disclosed in Japanese Patent Application Laid-Open No. 50800, and a device used in a building or underground shopping mall are disclosed. There is a known type that alerts the user by voice message. In the case of warning by voice message, it is desirable to simultaneously warn with a different voice message for each warning area in order to properly perform evacuation guidance.
No. 3297.

Conventionally, in this kind of disaster prevention monitoring device, a microprocessor outputs message read data to a voice synthesis ROM via an output buffer, and outputs a voice synthesis R.
In OM, for example, a special voice message such as "Your unit is a fire"
In addition, a common voice message such as "Fire on the XX floor" is sent to the other dwelling units on the floor except for the one where the fire occurred and all the dwelling units directly above the floor via the speaker. Is configured.

[0005]

By the way, a microprocessor is generally unstable when the power supply voltage is rising when the power is turned on. In some cases, the voice synthesis ROM is erroneously activated and a voice message is output from a speaker. There is a problem that it is output. In particular, the voice message transmitted by the disaster prevention monitoring device is an emergency message such as "Fire", and confusion occurs when the message is erroneously transmitted from the speaker.

Also, for example, "Your dwelling unit is a fire."
In a voice synthesis ROM that synthesizes a message such as “your”, “dwelling unit”, or “fire” in units of phrases, one phrase of voice data may be erroneously read when the power is turned on. In this case, confusion occurs when all the sounds of one phrase such as "Fire" are erroneously transmitted from the speaker.

The present invention has been made in consideration of the above-described conventional problems, and has as its object to provide a disaster prevention monitoring device capable of preventing a voice message from being erroneously transmitted when the power is turned on.

Since the section T2 until T becomes a high level is longer than the section T1 shown in FIG. 5, erroneous transmission of a voice message can be reliably prevented.

Next, the operation of the above embodiment will be described with reference to FIGS. In the example shown in FIG. 8, in a multi-family house on the first floor (F) to n floors, the repeater 10, the sensor 1a, and the speaker 2a in the dwelling unit shown in FIG. 1 are installed for a plurality of dwelling units on each floor. Also, the audio line L1 common to all the dwelling units
Are connected to the input sides 15a of the relays 15 in all the repeaters 10 in the apartment house, and the lines L2, L3 to for each floor are connected to the input sides 15b of the relays 15 for each floor.

As described above, the receiver 100 calls the repeater 10 and the like provided in each dwelling unit by designating a destination address by a polling method. It transmits its own address and smoke density signal, temperature signal or alarm signal. As shown in FIG. 8, for example, when it is determined that a fire has occurred in a certain dwelling unit on the first floor, an address indicating the fire occurrence location is applied to the MPU 112 from the repeater 10, and the repeater 10 in the dwelling unit where the fire has occurred The relay 15 switches from the input side 15b of the common audio line L2, L3 to the input side 15a of the common audio line L1 to all dwelling units for each floor.

Based on the address indicating the place where the fire occurred and the data set in the data setting ROM 140, the MPU 112 reads "Your dwelling unit is a fire" as shown in FIG. The two types of voice message data in this order
Read from the ROM 121, and in the section T1 of "your dwelling unit is a fire", only the relay 1301 for the audio line L1 common to all the dwelling units is turned on, all the other relays 1302-1316 are turned off, and then " In the section T2 of “(fire floor number is fire) floor”, the relay 1301 for the audio line L1 common to all dwelling units is turned off and the relay 130 corresponding to the fire floor is generated.
2 and the relay 1303 immediately above it are turned on, and this is repeated until the relay is restored.

That is, the repeater 1 of a dwelling unit where a fire has occurred
Only the relay 15 within 0 is the input side 15a of the audio line L1.
"Your dwelling unit is a fire"
Voice message is sent, and the voice message of "Fire on ((fire occurrence floor) floor)" is not sent. Also,
The voice message "Your unit is a fire" is not sent to other units on the floor except for the unit where the fire occurred, and the unit on the floor immediately above is not sent. Is sent.

Therefore, the voice synthesizing unit 120
Is configured to output a voice message in phrase units, the entire phrase such as "fire" or "fire" is erroneously transmitted from the speakers 2a and 125 when the main power supply 106 is turned on, causing confusion. Can be prevented.
