DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[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. As a method of assembling a voice message including the location and type of an emergency, there is known a method of assembling one sentence for each alarm code as shown in Japanese Patent Publication No. Sho 61-10880.

[0004]

In this type of disaster prevention monitoring device, a system using terminals such as a sensor or a relay that has an address and outputs fire information together with the address is used. There are systems that use terminals such as on-off sensors and repeaters that issue information simply by changing the impedance of the sensor line.

Therefore, the former system can output a detailed voice message in which the fire occurrence location is specified based on the address from the terminal, but the latter system gives an approximate voice message indicating the fire occurrence location and the like. Only output. However, there is a problem in that designing the two systems separately increases costs.

[0006] Further, even in a system using a terminal having an address, since the user side is various such as a building, a factory, an underground shopping mall, and an apartment house, the name of a fire occurrence place or the like is given to each user. When a different voice message can be output, an external memory for storing the sensor line or repeater line and the name of the installation location of the sensor or repeater for each user (that is, the fire occurrence location) is provided. Then, when a sensor issues a warning, a method of assembling a sentence such as "It is a fire at (fire place)" is known.

[0007] However, when the memory is externally connected as described above, if the memory becomes defective due to aging or the like, a voice message cannot be output at the time of a real fire, and the blame guidance cannot be appropriately performed. There is a problem. In view of the above conventional problems, the present invention can support both a system using a terminal whose address can be set and a system using a terminal whose address cannot be set. It is an object of the present invention to provide a disaster prevention monitoring device capable of outputting a voice message at the time of a real fire even if an external memory becomes defective in a system used.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a voice synthesizing unit for reading out a message for alarming an emergency such as a fire by voice and synthesizing the voice based on data, incorporated fixedly, a first storage means data for reading a fixed message from the speech synthesis unit is stored in advance, externally attached detachably,
A message that indicates the location of the disaster prevention event and has different contents for each user
A second storage unit in which data for reading out the message is stored in advance, and a readout in accordance with data set in the second storage unit when the second storage unit is normally connected. By applying the data to the voice synthesizing unit, a message including the location of the occurrence of the disaster prevention event is output, and when the second storage unit is not normally or originally connected, the message is preset in the first storage unit. Control means for outputting a fixed message by applying the read data to the voice synthesizer.

More specifically, the control means is a microprocessor and the first storage means is a program ROM built in the microprocessor. The speech synthesis unit of the present invention stores speech synthesis data for each phrase constituting one sentence in advance, and the control unit sequentially applies read data for each phrase to the speech synthesis unit. A voice message is composed and output as one sentence by the voice synthesis unit.

[0010]

According to the present invention, when the second storage unit is normally connected, the read data is applied to disaster events to the speech synthesis unit in accordance with the data set in advance in the second storage means A message containing the location of the occurrence is output. On the other hand, when the second storage unit is not connected normally or originally , the read data set in advance in the first storage unit is applied to the speech synthesis unit, and a fixed message is output. .

Therefore, it is possible to cope with both a system using a terminal whose address can be set and a system using a terminal whose address cannot be set. Even if the second storage means has a connection failure, a voice message can be output at the time of actual fire.

Is provided. As will be described later (FIG. 3), a data setting ROM 140 is connected to the program ROM 112a in the MPU 112 even in a system using an on / off sensor whose address cannot be set or in a system using an analog sensor. In the case of a failure, data (a read address or a code for the ROM 121 in the voice synthesis unit 120) for outputting a standard voice message at the time of a real fire is stored.

The MPU 112 controls the speech synthesizer 120 to output a speech message in phrase units.
Program ROM 112a or data setting ROM 140
Based on the data set in advance in the voice synthesis IC 1

As shown in detail in FIG. 3, the ROM 121 stores speech synthesis data for each of the phrases P1 to P8, and each of the phrases P1 to P8 has a plurality of different contents. Therefore, this phrase P
One sentence can be assembled by selectively reading out the data of each content for each of 1 to P8. For example, for each of the phrases P1 to P8, P1 ... "(onomatopoeia) just now" P2 ... "A" P3 ... "building" P4 ... "1" floor P5 ... "1" P6 ... "room No." P7 ... "fire alarm has been activated." P8 ... "Please check." (Onomatopoeia) The fire alarm has been activated in Building A, Room 1, Room 1. Please check. "

Here, the contents of the phrases P2 to P6 include the following phrase P7: "The fire alarm has been activated.", "The fire detector has been activated.", "A fire has occurred." Indicates the location of each event.
Therefore, it differs depending on the installation location of the system (that is, the user). In contrast, the phrases P1, P7 and P
The content of No. 8, that is, the message "(sound sound) fire alarm has been activated. Please confirm." Is a fixed content irrespective of each of the above events and the user.

Therefore, the program RO in the MPU 112
For example, the phrase P having fixed contents is stored in M112a.
The data (read address or code for the ROM 121 in the voice synthesis unit 120) for reading out 1, P7 and P8 is stored (programmed) in advance. Data for reading all the phrases P1 to P8 having different contents for each user is stored in a detachable data setting ROM1.
40 is stored in advance.

The data setting ROM 140 contains phrases P2 to P6 excluding the fixed message phrases P1, P7 and P8 stored in the program ROM 112a.

In addition to the relays 1301 to 1316, the amplifier unit 130 includes one power amplifier 137 for amplifying the output signal of the low-pass filter 123 of the voice synthesis unit 120, and a power supply unit for supplying power to the power amplifier 137. 138
Are provided, and an output terminal of the power amplifier 137 is commonly connected to one end of each of the relay contacts 1301 to 1316.

On the other hand, as an example, the relay contact 130
The other end of 1 is connected to the input side 15a of the relay 15 in all the repeaters 10 via the audio line L1 common to all the dwelling units, and the other ends of the relay contacts 1302, 1303 to are common to each floor. Are connected to the input side 15b of the relay 15 in the repeater 10 for each floor via the audio lines L2 to Ln. The number of relays 1301 to 1316 can be increased according to the number of floors of the apartment house to which the relays 1301 to 1316 are applied.

As shown in FIG. 4A, the data setting ROM 140 includes relays 1301 to 1 as shown in FIG.
The correspondence between 316 and the common housing and each floor is set in advance, and as shown in FIG. 4B, an address (relay 1) set via the address setting unit 13 in the repeater 10 is set.
0 and sensor address) and floor (ROM of voice synthesis unit 120)
The correspondence relationship of the read address or code (121) is set in advance. Of course, the setting data shown in FIG. 4 is an example and differs for each user.

As shown in FIG. 1, the data setting ROM 140 is provided in an MPU 1 via a connector or the like in a system capable of setting an address of the repeater 10 or the analog sensor 1b.
It is not used in a system using an on / off type sensor which is external to 12 and whose address cannot be set. Next, the operation of the MPU 112 will be described with reference to FIGS. First, in FIG. 5, when the terminal issues an alert, step S
The process proceeds from step 1 to step S2. Here, in the example shown in FIG. 1, the terminal that has issued the alert is the repeater 10 whose address can be set, and the analog sensor 1b. However, there are cases where the address cannot be set in the system configuration.

In step S2, the data setting ROM 140
Check whether the data setting ROM 140 is normal and whether the data setting ROM 140 is normal.
The processing shown in FIG. 6A is executed (steps S3 → S4). If the processing is not normal, the processing shown in FIG. 6B is executed (steps S3 → S5). In the process shown in FIG. 6A, as shown in FIG. 4B, based on the terminal address and floor set in the data setting ROM 140, read data indicating the floor of the terminal that issued the alert and another phrase The voice data is read out by applying appropriate read data to the voice synthesizing unit 122 (step S11), and then the relays 1301 to 1316 corresponding to the floor are selectively turned on, thereby specifying a fire occurrence place and the like. A message of one sentence with detailed contents is output (step S21).

On the other hand, in the processing shown in FIG.
The voice data is read by applying the read data of the fixed phrases P1, P7, and P8 stored in the program ROM 112a in the MPU 112 to the voice synthesizer 122 (step S31), and then, for example, all the relays 1301 to 1316 are turned on. By doing so, a message of one sentence having simple contents not including the fire occurrence location and the like is output (step S32).

Therefore, in the above embodiment, the repeater 1
0. If the system uses a terminal whose address can be set, such as the analog sensor 1b, and the external data setting ROM 140 for the system is normally connected, detailed contents such as a fire occurrence location Message can be output. Even in a system using a terminal whose address can be set, the data setting ROM 1
A fixed message can be output when the device 40 is not connected normally or in a system using an on / off type sensor whose address cannot be set, that is, a system in which the external data setting ROM 140 is not originally connected. In the former case, even if the data setting ROM 140 has a connection failure, a voice message can be output at the time of an actual fire, so that a fail-safe function is provided and evacuation guidance can be appropriately performed.

Even when the data setting ROM 140 is connected, a message may be output by combining the fixed phrase stored in the program ROM 112a with the phrase stored in the data setting ROM 140. . 7 and 8 show an external data setting ROM for the system shown in FIG.
FIG. 6 shows the operation when the connection is normal, that is, the processing shown in FIG. In the example shown in FIG. 7, in the apartment house on the first floor (F) to the nth floor, the repeater 10 shown in FIG.

In addition, the audio line L1 common to all the dwelling units is connected to the input side 15a of the relay 15 in all the repeaters 10 in the apartment house, and the lines L2 and L3 to each floor are the input side of the relay 15 for each floor. 15b. In this example, the voice message will be described more simply than that shown in FIG.

As described above, the receiver 100 calls the repeater 10 provided in each dwelling unit by designating the destination address in a polling manner. It transmits its own address and smoke density signal, temperature signal or alarm signal. As shown in FIG. 7, for example, when it is determined that a fire has occurred in a certain dwelling unit on the first floor, an address indicating a 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.

The MPU 112, based on the address indicating the place where the fire occurred and the data set in the data setting ROM 140, 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.
