Description

Description: TECHNICAL FIELD The present invention relates to an alarm device for a guest at an accommodation facility such as a hotel or a nursing home.

(Problems to be solved by the invention) In a facility where many people stay, such as a hotel and a ryokan, when a disaster such as a fire occurs, there is a means to activate the alarm device to notify the danger with an emergency bell or the like and to evacuate. Has been adopted. However, recently, rooms have high airtightness, and an alarm sound such as an emergency bell attached to a corridor or ceiling cannot always wake up a guest who is sleeping deeply in the room. Further, even if the user wakes up, it may be difficult to find an evacuation route if the light is not turned on due to a power failure.

The present invention emits an alarm sound at a location near the guest when the above-mentioned disaster occurs, and furthermore, can reliably transmit the occurrence of an abnormality by means such as sound, video, lighting of an alarm lamp,
It is an object of the present invention to provide an alarm device for accommodation hotel guests having a function of easily finding an evacuation route by carrying a lit alarm lamp.

(Means for Solving the Problems) The alarm device of the present invention comprises: (A) a transmitter for transmitting an alarm signal;
Equipped with a television receiver and an alarm light as an alarm, (B)
The transmitter makes an alarm signal a high frequency, mixes it with a TV signal using a CATV system transmission line in the facility, and transmits it.
(C) The television receiver receives the alarm signal from the CATV system transmission line, turns on the power, and outputs one of the alarm sound, audio, and video.
(D) the alarm lamp is in a standby state in which the charging terminal is plugged into a power outlet and the rechargeable internal storage battery is charged, and Means for receiving an alarm signal from the leaked radiation from the line and the antenna input terminal of the TV receiver to notify the occurrence of an abnormality due to the lighting of the illuminator and the generation of an audible alarm, and withdrawing the charging terminal from the power outlet Means for stopping the alarm sound when the alarm occurs.

(Operation) The present invention has the above configuration, and this alarm device
Since the alarm signal has a high frequency and is mixed with the television signal using the existing CATV system transmission line and is transmitted, it is not necessary to provide a new transmission line for the alarm signal in an ordinary hotel or the like having a CATV system. The television receiver can be used as it is as an alarm signal receiving / warning device. The warning light does not require a separate transmission circuit for operation, and
Receives and issues an alarm signal of leakage radiation from the TV transmission line.

(Embodiment) The drawing shows the CATV of an accommodation facility incorporating the alarm device of the embodiment.
It is a figure showing a system. The alarm device includes a transmitter 1 for transmitting an alarm signal, a television receiver 2 for receiving the alarm signal and issuing an alarm, and an alarm lamp 3. The CATV system is configured by connecting a television antenna 4 and a front-end device 5 such as a VTR to a television receiver 2 in each room 6 via a CATV transmission line 7.

The transmitter 1 is connected to the transfer terminal of the automatic fire alarm 8, and an abnormal signal detected by the smoke detector 9 installed in each room 6 is received by the transmitter 1 via the fire alarm 8. can do. The fire alarm 8 also has a function of operating the emergency bell 10.

When the transmitter 1 receives the abnormal signal generated by the fire alarm 8, the transmitter 1 converts the signal into a high-frequency alarm signal of 153.64 MHz and issues the alarm. This signal enters the mixing filter 12a via line 11 from the input terminal, passes through a 153.64 MHz bandpass filter and exits at the output terminal. This mixing filter 12a has a 90-degree signal transmitted from the front-end device 5 through another input terminal.
High frequency signal of ~ 108MHZ and 170 ~ 222MHZ, 153.64M
It passes through the HZ band rejection filter and exits the output terminal and is mixed with the 153.64 MHZ alarm signal.

The signal output from the mixing filter 12a is mixed
, A part enters the mixing amplifier 13 and is amplified together with the signal inputted from the antenna 4. The 153.64 MHZ alarm signal does not pass through the amplifier 13, but enters the mixing filter 12 c via the bypass line 11 ′, is mixed with the television signal amplified by the amplifier 13, and is transmitted on the CATV main line 14, a branched coaxial cable. 7 and transmitted to the television receiver 2 in the room 6.

The television receiver 2 has a function of receiving a normal television broadcast, receives and decodes an alarm signal transmitted from the transmitter 1, turns on the power, and issues an alarm or sound to notify the occurrence of an abnormality. It has the function to do. The teleb receiver 2 can be further provided with a function of notifying the occurrence of a fire or the like and the evacuation method by video.

The warning light 3 in the room 6 is provided with its charging terminal inserted into a power outlet 15 near the television receiver 2. The warning light 3 is a rechargeable type with a built-in storage battery, and is always equipped with a charging terminal connected to a power outlet 15, so that the storage battery is always fully charged. When an abnormality occurs, a warning signal which is slightly leaked and radiated from the connection between the CATV transmission line 7 and the input terminal of the television receiver 2 is received and decoded, the built-in illumination lamp is turned on, and the electronic buzzer is turned on. Emit an audible alarm. When the lamp is turned on and the warning lamp 3 that emits the warning sound is pulled out from the power outlet 15, the warning sound stops and only the lamp continues to light.

The warning light 3 may emit a warning sound composed of two sounds that are alternately switched. As an example of the means for alternately switching the alarm sounds of the two frequencies, a method of using a rectangular wave and intermittently activating and stopping the DC power supply voltage of the local oscillator of the high-frequency receiving unit and the high-frequency amplifier using the rectangular wave is used. is there.

The warning light 3 is inserted into a power outlet 15 within about 3 m from the television receiver 2, receives a warning signal from the transmitter 1 as a leaked radiation, demodulates the signal, decodes the signal, controls the signal,
Sound the electronic buzzer and turn on the lighting. When the release signal is received, it is decoded, the electronic buzzer is stopped, and the illumination lamp is turned off.

The guest staying in the room 6 hears the alarm sound of the electronic buzzer, jumps up and relies on the light of the lighting lamp lit in the dark to pull out the alarm light 3 from the power outlet 15 and only the electronic buzzer stops. . It has a lit warning light 3 and can evacuate while illuminating. In addition, the lighting time of the warning light 3 is 30 minutes or more, and there is a sufficient margin to continue lighting during the time required for evacuation.

Although the transmitter 1 of this embodiment uses a commercial current of AC 100 V as a power supply, it incorporates a lead storage battery and maintains its function even during a power failure. Since the transmission signal from the transmitter 1 is FM-modulated by the RESET signal in normal times, the operation of the receiver side is in a stopped state. When the alarm signal is issued, the transmission signal is modulated by the SET signal, and the reception signal is received. Operate the machine side.

(Effects of the Invention) As described above, the alarm device of the present invention is hermetically sealed because the receiving / foaming machine such as the television receiver and the warning light installed in the room issues an abnormality by sound, video, and lighting. Even in a closed room, it can be reliably transmitted to guests. In addition, since the evacuation can be performed while illuminating with a lit warning lamp, safety during evacuation can be further enhanced. Existing CATV transmission lines and television receivers can be used as they are, reducing equipment costs and management burden.
