SOLUTION: This system consists of a transmitter 1 which has an incorporated sensor and transmits sensed information as a peculiarly set ID signal, and a receiver 10 which receives the transmission signal from this transmitter and analyzes it to notify a user of the analysis result. One of more repeaters 11 and 12 are interposed between the transmitter 1 and the receiver 10, and <=500 ×V weak radio wave is used for signal transmission. The receiver 10 is provided with an LCD device and/or a motor vibration. The timer circuit of a CPU incorporated in the receiver 10 acts to repeat a notice means infinitely in the case that sensed information is alarm information reporting a danger, and a single frequency is used for signal transmission. The receiver 10 represents, for example, a wristwatch type information notice system.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information notification system, and mainly relates to a door chime, a telephone ringing sound, and other alarms such as a gas leak and a fire that occur when a hearing-impaired person takes off a hearing aid at home or the like. The present invention also relates to a convenient information notification system that can be used in construction sites, hospitals, offices, and the like where environmental noise is severe in the environment.

[0002]

BACKGROUND OF THE INVENTION Generally, for a hearing-impaired person who uses a hearing aid, wearing the hearing aid is extremely annoying and cumbersome, and is often removed at home or the like. Or the phone rings,
Alternatively, even if the alarm clock sounds during sleep, the user may not notice it and spend time. If this alarm is a gas leak or a fire alarm, a very dangerous condition may be caused. In addition, when there is severe noise or the like in the surrounding environment, not limited to the hearing-impaired, it is not rare that the above-mentioned information is heard.

[0003]

However, at present, there is no disclosure of a device for positively resolving the above-mentioned situation, so that a hearing-impaired person is forced to wear a troublesome hearing aid, and in an environment with severe ambient noise. Even so, the use of megaphones and other means has been intense.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned circumstances and problems.
By wearing a receiver mainly for each individual, it is possible to quickly inform information such as sound that informs changes in the situation and to be able to grasp the situation, and to make it as small and light as possible, It is an object of the present invention to provide an information notification system that does not cause any burden even if it is attached and does not hinder communication such as ordinary television and radio.

[0005]

In order to achieve this object, an information notification system according to the present invention has a built-in sensor for sensing various kinds of information, and transmits a sensed information as an ID signal uniquely set. And a receiver that finally receives a transmission signal from the transmitter, analyzes the signal, and notifies the holder of the transmission signal. It is characterized in that a repeater is interposed, a weak radio wave of 500 microvolts or less is used for the signal transmission, and an LCD display display and motor vibration are used for the receiver. One or both of them are provided, and when the above-mentioned various information is alarm information for notifying danger, a timer circuit of a CPU built in the receiver operates to notify infinitely. And wherein the repeating unit, the signal transmission described above is characterized in that are using a single frequency, the above-mentioned receiver is characterized in that you have to watch type.

[0006]

According to the above construction, the required
Alternatively, various information selected and set by each person can be recognized almost in real time without hearing, and the system itself and the receiver and transmitter are also reduced in size and weight, and not only for the wearer of the receiver but also for the appearance. It can be something that does not feel uncomfortable.
