Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention consists of a living room, a common area, and a management room, and when an emergency situation occurs, a notification signal is sent to the management room by a reporting means for processing. Regarding emergency radio notification system.

[Conventional technology]

In buildings such as dormitories, hotels, and apartment complexes where many residents live in private spaces separated by walls from each living room or from common areas such as hallways, the internal conditions may differ from those of adjacent living rooms or common areas. can't know.

Therefore, if an emergency occurs, it will remain unknown unless residents report it. Such problems become especially serious when elderly people live alone.

Therefore, an emergency radio notification system is being considered for allowing residents to report when an emergency situation such as a sudden illness or accident occurs in dormitories, hotels, apartment complexes, hospitals, etc. as described above.

FIG. 2 shows a conventional example.

The conventional emergency radio notification system has an antenna 21, a radio 29, and an antenna 31 in the living room and common areas, as shown in Fig. 2.
-1 and radio 32-1, antenna 31-2 and radio 32
-2 is placed so that notification signals can be transmitted from pendant radios 26 and 34 worn by residents. Furthermore, by combining these with other notification means, for example, the push button 24 for the toilet, the push button 25 for the bathroom, the push button 3 for the common area.
3 so that a notification signal can be transmitted by pressing a button, and a fire sensor 23 and a life rhythm sensor 22 are installed in the living room to transmit a fire detection signal and a signal of abnormality in the life of the resident. We also make it possible.

The life rhythm sensor 22 detects the movement of a person using, for example, infrared rays, and determines that it is an emergency situation if the resident collapses due to a sudden illness or accident and does not move for more than a certain period of time. The control unit 35 in the management room receives the above-mentioned notification signals from the living room through the intercom 28, and further receives the notification signals from the wireless devices 32-1, 32-2 and the push button 33 in the common area, and also receives the notification signals from the common area push button 33. Based on the status of the device 39, it is determined whether the room is occupied or not, and the display contents of the information display panel 36, group display panel 37, and sub-display panel 38 in the management room are controlled.

[Problem to be solved by the invention]

However, in conventional emergency radio reporting systems, for example, helical whip antennas are used as antennas for radio receivers, but there is a problem in that multiple receptions occur at multiple locations, making it impossible to identify the location of the caller. This is because, in order to enable wide-area reception, especially in common areas, multiple antennas are installed in a certain range to increase reception sensitivity, which also causes signals from the pendant radio 6 in the living room to be received. It is something. Moreover, increasing the receiving sensitivity causes problems such as the receiver becoming more susceptible to noise and more likely to malfunction, resulting in frequent false alarms and system failures.

Also, as shown in the figure, all signals in the living room are sent to the ink-phone 2.
8 to the control unit 35 in the management room, there is a problem that the notification signal cannot be sent or received during a call.

The present invention has been made to solve the above-mentioned problems, and aims to provide an emergency radio notification system that allows reliable reporting, makes it easy to identify the location of the caller, and is resistant to noise.

[Means to solve the problem]

To that end, the present invention consists of a living room, a common area, and a management room.
In the emergency radio notification system, an antenna is installed in each room and a leaky coaxial cable is installed in the common areas. The system is characterized in that signals from wireless transmitters in living rooms and common areas are processed by wireless receivers, and signal processing for the intercom system is separated.

Furthermore, the intercom system is configured to process signals from push buttons, fire sensors, and life rhythm sensors, and a partition wall with shielding performance is used between the living room and the common area.

[Effect]

In the emergency radio notification system of the present invention, an antenna is installed in each living room, a leaky coaxial cable is installed in the common area, and the signals from the radio transmitters in the living room and the common area are processed by radio receivers. Duplicate reception between the living room and the common area can be avoided by adjusting the reception sensitivity of . Furthermore, since the signal processing for radio reception and the signal processing for the intercom system are separated, it is possible to reliably transmit a report signal using a radio signal even if the intercom system is busy.
