Abstract

PURPOSE:To output earthquake information instantly as a voice by applying a synthesized voice signal when an earthquake is detected and sounding a synthesized voice determined individually in advance from each receiver. CONSTITUTION:When an earthquake happens, an earthquake detection unit 1 detects it to output an earthquake detection signal So. In response to the detection signal So, the 1st control signal S1 and the 2nd control signal S2 are outputted from a control circuit 2. The 1st control signal S1 excites a drive coil 4P of a relay 4 to contact a moving contact 4c to a fixed contact 4a, and on the other hand, the 2nd control signal S2 starts a synthesized voice reproducing circuit 3 after the end of operation of the relay 4 by the 1st control signal S1 awaited. A synthesized voice signal converting circuit 18 reproduces a synthesized voice signal S3 based on a synthesized voice data read from a synthesized voice data memory 17. The synthesized voice signal S3 is inputted to a voice signal amplifier circuit 6, where the signal is amplified and sounded from a speaker 7 as an earthquake synthesized tone.

Description

[Detailed Description of the Invention] Technical Field> The present invention relates to a device that has both a broadcast wave reception function and an earthquake information reporting function, and in particular, the present invention relates to a device that has both a broadcast wave reception function and an earthquake information reporting function. This relates to an earthquake information notification device that is capable of emitting earthquake information using predetermined synthesized voices (prior art).
It is known that when an earthquake occurs, earthquake information is transmitted all at once to radio receivers within the service area using broadcast waves.

However, with such conventional earthquake information broadcasting devices, the same earthquake information is simultaneously broadcast to listeners within a fairly vast service area, making it difficult to transmit individual information to selected areas. In other words, in the event that one service area is hit by a local earthquake, by broadcasting, earthquake information will be transmitted to areas other than the expected earthquake area, and unnecessary 7G disturbances will be avoided. On the other hand, even if the entire service area is hit by an earthquake, the intensity of the earthquake and the extent of the damage will vary from place to place within the vast service area. It has been difficult to select and transmit individual earthquake information corresponding to the situation of each location for each location using conventional systems that use simultaneous broadcasting.

Furthermore, in general, in the broadcasting business, in order to accurately process a large amount of information, it is necessary to follow certain procedures from information gathering to programming and broadcasting. , it is difficult to immediately broadcast it live, and the reality is that it takes a considerable amount of time to convey it to listeners within the service area.

Therefore, when an earthquake occurs, there is a need for an earthquake information notification device that can selectively provide individual earthquake information tailored to the situation in that area only to the residents of the expected earthquake disaster area.

[Object 1] The purpose of the present invention is to solve the problem of the difficulty in providing individual information in a selective manner due to the restriction of configuration 1 due to the use of broadcasting in the prior art described in -1-. When an earthquake is detected by the detection unit, a synthesized voice signal from a synthesized voice playback circuit that starts in response to this is supplied to the sound emitting unit of the radio receiver to generate individually predetermined synthesized voice. This makes it possible for each radio receiver to emit a sound, thereby creating an excellent earthquake information notification system that can instantly provide earthquake information individually set for each radio receiver as audio from the radio receiver at the earthquake detection location. This is what we intend to provide.

According to the structure of the present invention, when an earthquake occurs, an earthquake detection unit detects this and supplies an earthquake detection signal to a control circuit, and in response to this, the control circuit Second

The transfer switch means switches the input signal to the sound emitting stage of the radio receiver to supply the synthesized speech signal from the synthesized speech reproducing circuit to the sound emitting means, while at this time, the second input signal from the control circuit is switched. In response to the control signal, the synthesized speech reproduction circuit is designed to output a synthesized speech signal representative of individual earthquake information previously stored in a memory within the circuit.

As the vibration detection elements (not shown) constituting each of the transverse wave sensor 10 and the longitudinal wave sensor 11, for example, an F2O-V30 element (piezoelectric element) manufactured by Keishi Electric Co., Ltd. can be adopted.

On the other hand, as shown in FIG.
The address signal generator TILL is connected to the synthesized voice data memory 17 through an address bus line, and further connected to the synthesized voice signal conversion circuit 18 through a synchronization signal line. The synthesized voice data memory 17 is connected to a synthesized voice signal conversion circuit 18 through a data path line, and its output line is connected to a fixed contact 4d of the relay 4 via a low-pass filter 17, as shown in FIG. It is extending.

As the synthetic voice signal conversion circuit 18, for example, Oki Electric (
MSM5205R3 type integrated circuit manufactured by Co., Ltd. can be used.

In such a configuration, in a steady state in which no earthquake occurs, that is, in a steady state in which the first control signal S1, which will be described later, is not received from the control circuit 2, the drive coil 4P remains in a non-excited state, and the drive coil 4P remains in a non-excited state. It is possible to operate as That is, when the power supply 8 is turned on, the movable contact 9a of the +1 switch 9A is connected to the fixed contact 9a', and power is supplied to each circuit of the receiver.
Since C is kept connected to the fixed contact 4b, the audio signal S4 from the broadcast wave demodulated by the audio signal demodulation circuit 5 is supplied to the audio amplification circuit 6 through the movable contact +fi4c, where it is amplified. and the sound is emitted from the loudspeaker 7.

When an earthquake occurs, the earthquake detection unit 1 detects this and outputs an earthquake detection signal SO. That is, the transverse wave component and the longitudinal wave component of the seismic wave are detected by the transverse wave sensor 1, respectively.

The outputs of 11 are further amplified by a transverse wave signal amplifier 12 and a longitudinal wave signal amplifier 13, respectively, and then added in a vibration wave synthesis circuit 14, and the addition result represents a composite value of both components of the seismic wave. It is supplied as a signal to the vibration wave analysis circuit 15, where it is subjected to signal processing such as correlation analysis,

On the other hand, the -1- earthquake detection signal So is also supplied to the control circuit 2, so in response to the detection signal So, the control circuit 2

Then, synthesized voice data related to earthquake information stored in advance as digital codes in the synthesized voice data memory 17 is read out in accordance with the increment of the address signal. At this time, in response to the clock pulses simultaneously output from the address signal generator 16, the synthesized speech signal conversion circuit 18 converts the synthesized speech data memory 17 while ensuring synchronization with the read operation described above. The synthesized speech signal S3 used to reproduce the synthesized speech signal S3 based on the read synthetic speech data passes through a low-pass filter 17 to remove interference noise and the like, and then is manually input to the speech signal amplification circuit 6. , where it is amplified and emitted from the loudspeaker 7 as an earthquake information synthesized sound.

Note that when reading the synthesized voice data from the L synthesized voice data memory 17, the earthquake detection unit l supplies the control circuit 2 with different earthquake detection signals So depending on the seismic intensity, for example. In response to separate control signals S2 output from the control circuit in response to various earthquake detection signals, the address reliability generator 1B generates a series of address signals specifying addresses of different memory desired areas depending on numbers. It is also possible to supply optimal earthquake information for each seismic intensity by supplying the synthesized speech data to the synthesized speech data memory 17, thereby emitting synthetic speech W for each seismic intensity.

Effects> As described in 1- below, according to the present invention, when an earthquake occurs, it is detected by the earthquake detection unit provided for each earthquake information notification device, and the earthquake is detected individually for each earthquake information notification device in advance. By guiding the synthesized voice number 43 representing prescribed earthquake information from the synthesized voice reproducing circuit to the sound emitting part of the radio receiver and emitting the earthquake information so that it can be heard, the earthquake information notification device can be used. Important safety information and safety information is provided to each earthquake information alarm device that detects an earthquake for each installation location, so it is completely possible to avoid causing unnecessary confusion to residents in areas where earthquakes are not detected. avoided, and
Even when earthquake detection locations are spread over a wide area, the excellent effect of being able to provide earthquake information that is most suitable for the situation assumed at each location is achieved.

The synthesized voice emitted at that time is not from a radio broadcast, but from a synthesized voice signal stored in advance in the memory of the synthesized voice playback circuit, and is not related to the organization of the broadcast program, etc. Sound emission can be started simultaneously with detection, which has the excellent effect of quickly transmitting earthquake information.

Furthermore, by sharing the sound emitting part of the radio receiver and emitting synthesized speech representing earthquake information, it can be used as a radio receiver in a steady state where no earthquake is detected. It also has the advantage that it has much higher functionality per cost and is more economical than a single configuration consisting of an earthquake information notification device that is used extremely infrequently.
