As shown in FIG. 1, when a visitor makes a call from the entrance handset 41 of the intercom system 4 installed outdoors, the ring tone of the living room master unit 42 installed in the room A sounds, and the microphone of the transmitter 2 27. Although the transmitter 2 is also placed in the room A in FIG. When the CPU 25 of the transmitter 2 identifies that the sound input from the microphone 27 is a ringing tone that is stored and registered in advance in the storage unit 24 , the CPU 25 wirelessly transmits a notification signal from the wireless interface 23 . At the same time, by lighting the LED 21 or emitting a sound from the speaker 28, it is also possible to notify the surroundings of the transmitter 2 that the living room master unit 42 is being called.

The notification sound at this time may be generated by amplifying the ringing sound emitted by the living room base unit 42, or may be generated by preparing a unique notification sound in the sound unit 36. - 特許庁

In order for the wireless notification system 1 described above to operate, it is necessary to register the ringing tone of the living room base unit 42 in the transmitter 2 in advance. As shown in FIG. 3, this sound registration is performed by operating the registration switch 22 to start the sound registration mode in which the transmitter 2 can register the sound. When the sound registration mode is activated, the transmitter 2 inputs a ringing sound from the microphone 27 within a certain period of time under the control of the CPU 25 and stores and registers it in the storage unit 24 . However, in order to sound the ringing tone to be registered, it is necessary to press the call button 43 of the entrance handset 41 arranged outside the entrance. At this time, it is assumed that a time longer than the travel time of the worker for sound registration to the entrance passes from when the sound registration mode of the transmitter 2 is started to when the call button 43 is actually pressed and the ringing tone sounds. Become. Therefore, if an irrelevant noise occurs before the ringing tone sounds, there is a risk that the noise will be used as a registered tone. Also, even if a plurality of people work for sound registration, it is necessary to inform the person who operates the entrance slave unit 41 of the timing. Therefore, the present invention employs the following embodiments.

In the wireless notification system of the first embodiment of the present invention, as shown in FIG. 4, even if the registration switch 22 of the transmitter 2 is operated to activate the sound registration mode, for example, The CPU 25 is caused to perform control such that the sound input from the microphone 27 is not registered within a predetermined period of time such as 30 seconds, and the sound input after the predetermined period of time is stored in the storage section 24 as a registered sound. As a result, it is possible to secure a time allowance until the user goes to the entrance slave unit 41 and presses the call button 43 in order to sound the ringing tone to be registered. Since the operator can know the sound, the sound to be registered in the transmitter 2 can be sounded at an appropriate time and surely registered. The CPU 25 determines that the sound registration is completed when the sound input from the microphone 27 becomes silent and continues for about 1 to 2 seconds, and terminates the sound registration mode. It should be noted that the predetermined time for suspending sound registration (hereinafter referred to as "sound registration suspension time") may be changed arbitrarily.

When the registration switch 22 is operated, the CPU 25 lights or blinks the LED 21 to notify the operating person that the time measurement of the sound registration suspension time has started. Then, when the actual sound registration is started after the sound registration suspension time elapses, the LED 21 can be notified by a lighting method different from that during the sound registration suspension time (the lighting color is changed, the blinking pattern is different). Furthermore, when the sound registration is completed, the completion can be notified by lighting or sound from the speaker 28 .

In the wireless notification system according to the second embodiment of the present invention, the portable receiver 3 can also be used for sound registration in the transmitter 2 . As shown in FIG. 5, when the registration switch 22 is operated to activate the sound registration mode, the CPU 25 starts measuring a sound registration suspension time, such as 30 seconds. On the other hand, after the sound registration mode is activated, the sound registration operator carries the receiver 3 and moves to the entrance slave unit 41 . When the sound registration suspension time elapses, the CPU 25 starts sound registration and wirelessly transmits a sound registration start signal to the receiver 3 via the wireless interface 23 .

The CPU 35 of the receiver 3 that has received the sound registration start signal via the wireless interface 33 notifies that the actual sound registration of the transmitter 2 has started by lighting or blinking the LED 31 . With this notification, the sound registration operator can accurately recognize the start of sound registration of the transmitter 2 and press the call button 43 at an appropriate timing, so that the ring tone of the living room main unit 42 can be properly transmitted to the transmitter 2. can be registered with

When the transmitter 2 completes sound registration and ends the sound registration mode, the CPU 25 wirelessly transmits a sound registration end signal to the receiver 3 . The CPU 35 of the receiver 3 can notify the operator holding the receiver 3 of the termination of the sound registration mode by controlling the lighting/blinking of the LED 31 to end when the signal is received.

Various notifications of the sound registration mode by the transmitter 2 and the receiver 3 may be made by sound using the speakers 28 and 38 in addition to or instead of the light using the LED 31 .

Furthermore, by installing a plurality of receivers 3 at distant locations, it is possible to notify that the ringing tone of the entrance main unit 42 is sounding simultaneously at a plurality of locations away from the transmitter 2 .

It should be noted that the wireless notification system of the present invention is not limited to the above-described embodiments, and it is possible to modify the shape and configuration of each part appropriately without departing from the scope of the invention. For example, the functions of the transmitter 2 can be integrated into the living room main unit 42 of the intercom system 4 .
