BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver for transmitting and receiving synchronously, and an alarm device including at least one transmitter cooperating with the receiver, and more particularly, to a transmitter holding the transmitter. When a person leaves the reception area of the receiver,
The present invention relates to an alarm device that operates a sound generator or a vibrating body of a receiver to warn that a person or the like holding a transmitter has been moved out of a reception area of the receiver.

[0002]

BACKGROUND OF THE INVENTION The problem of how to care for old people, children or patients who are treating illnesses is becoming increasingly important. Therefore, alarm devices have been developed to effectively protect the patient being treated from being lost or to rescue those in need.
Alternatively, it is difficult to keep your valuables in a visible area to prevent them from being stolen or lost. Valuables are stolen by thieves,
That often happens.

FIGS. 7 and 8 show a conventional alarm device developed to solve the above problem. Such an alarm device includes a transmitter unit 11 and an associated receiver unit 12. Transmitter unit 11
Is, as shown in FIG. 7, an encoding selection switch 111,
Encoder 112, transmitting circuit 113, and antenna 114
It has. The encoding selection switch 111 serves to adjust the combination code. The combined code encoded by the encoder 112 is converted into a radio wave by the transmission circuit 113, and the radio wave is transmitted via the antenna 114.

As shown in FIG. 8, the receiver unit 12 includes an antenna 121, a receiving circuit 122, a decoder 123, a decoding selection switch 124, and an alarm control circuit 1.
25 and a loudspeaker 126. The signal from the transmitter unit 11 is transmitted to the receiving circuit 1 via the antenna 121.
22 and is decoded by the decoder 123. Next, the alarm control circuit 125 receives the signal. When the receiver unit 12 cannot receive the signal, the alarm control circuit 125 sounds the sound generator 126 to warn the user with a sound.

[0005]

However, the structure of the conventional product described above has the following problems when used. Conventional alarm devices are used to match the signal reception and transmission of the receiver unit 12 and the transmitter unit 11,
Encoding selection switch 111 and decoding selection switch 124
Is used. (Multiple transmitter units cause interference with each other.) Thus, one alarm device only has one transmitter unit 12 to combine with one transmitter unit 12 and one alarm unit at a time. It is not possible to combine several transmitter units into one receiver unit. This greatly limits the practical use of this alarm device. The transmitter unit of a conventional alarm device transmits a signal continuously, or intermittently transmits a signal that lasts for a long time. Therefore, the power consumption is very large. Furthermore, the receiver is always in a receiving state continuously. This shortens the life of the battery, requires frequent replacement with new batteries, and always requires a spare battery. The signal reception and transmission of the conventional alarm device is a relatively complicated circuit, and the coding selection switch 1 is relatively expensive.
11 and a decryption selection switch 124. Furthermore, since the size of each component is large, the size of the alarm device cannot be reduced and the alarm device cannot be carried. The present invention solves these problems and provides a synchronous receiving and transmitting alarm device that keeps valuables and the person under treatment from leaving a preset controllable range with parents. Provision is the first purpose.

[0006] Another object of the present invention is that when a treating person, such as a patient or the elderly, needs help, the guardian is effectively alerted and informed to rescue them. An object of the present invention is to provide an alarm device. It is a further object of the present invention to provide an alarm device in which one receiver unit is always coupled with a multiplex transmitter unit to make it easier to carry and improve the user's convenience. Still another object of the present invention is to provide an alarm device having a function of notifying a user of a telephone call.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The alarm device according to one embodiment of the present invention includes, as shown in FIGS. 1 and 2, at least one transmitter unit that transmits and receives synchronously,
And one receiver unit.

As shown in FIG. 1, the transmitter unit includes a pulse control circuit 22, a quartz clock 23, a transmission circuit 24, and an antenna 25. The receiver unit includes an antenna 31 and a receiving circuit 3 as shown in FIG.
2, a pulse and alarm control circuit 33, a quartz clock 34, a receiving circuit controller 35, and a sound generator or vibrator 36.

[0015] The alarm device is operated as described below. Transmitting a signal from the transmitter unit : based on a clock from the quartz clock 23, sending out pulses at precise predetermined time intervals. Then, the transmission circuit 24 performs a transmitting operation each time a pulse is received from the pulse control circuit 22. The pulse generated by the quartz timepiece 23 and the pulse control circuit 22 is transmitted from the transmission circuit 24 through the antenna 25 as a pulse signal. This pulse signal is a clock pulse transmitted intermittently. Also,
The transmission time of the clock pulse is shown in FIG.

Receiver unit signal reception : The receiver unit can automatically receive the pulse signal from the transmitter unit. For this purpose, the pulse and alarm control circuit 33 transmits a pulse (B in FIG. 3) at a predetermined time interval synchronized with the pulse signal shown in FIG. Outputs an alarm control signal when cannot receive a pulse signal. The receiving circuit controller 35 is accurately controlled by the pulse and the pulse transmitted from the alarm control circuit, and the receiving circuit 32 is set in a receivable state in synchronization with the transmission time of the transmitter unit. Antenna 31
Are identified by the receiving circuit 32 and the pulse and alarm control circuit 33. If the received pulse signal is correct, the receiving circuit controller 35 closes the receiving circuit 32 in a timely manner (non-receiving state) and waits for the next transmitted pulse signal. And
The receiving circuit reopens to receive the signal before the next transmitted pulse signal is emitted.

When the receiving circuit 32 cannot receive the pulse signal transmitted once or several times continuously, the sound generator or the vibrating body 36 is driven by the pulse and the signal from the alarm control circuit 33 to generate a sound. Alternatively, a vibration is generated to warn the holder of the receiver unit. For example, a person, such as an old man or a child, or a valuable with a transmitter unit is at a distance from the holder of the receiver unit and the receiver unit is When the transmitter unit is moved out of the reception area so that the transmitted signal cannot be received, the holder of the receiver unit drives the sound generator or the vibrator 36 to warn by sound or vibration, An alarm effect is achieved.

In practical use, one receiver unit can cooperate with two or more transmitter units simultaneously. The receiver unit can be locked to the transmission time of each pulse of the transmitter unit, as shown in FIG. For example, as shown in FIG. 4, when the open time of the receiver unit is E and the time at which each transmitter unit transmits a signal is C and D, the open time of the receiving circuit 32 is the transmission time of each transmitter unit. We can deal with it at the same time. Thus, one receiver unit can simultaneously receive and monitor multiple transmitter units simultaneously. For example, if the holder of the receiver unit needs to take care of the child and has a mobile phone at the same time, two transmitter units can be installed on both the child and the mobile phone, It is possible to prevent the user from losing the phone or forgetting the mobile phone.

Referring to FIG. 5, another embodiment of the present invention will be described. In this embodiment, a radio wave detection circuit 21 triggered by a call or a button of a mobile phone is provided.
Is added to the transmitter unit, and the transmitter unit triggers the radio wave detection circuit 21 added to the transmitter unit by a telephone call or a button. When the holder of the transmitter unit urgently needs help, when the holder presses a button attached to the transmitter unit and activates the detection circuit 21, the waveform of the transmission wave of the transmitter unit changes, Or, stop the transmitter unit from transmitting the signal. Then, the receiver unit generates sound or vibration, and warns the holder of the receiver unit for rescue. In this embodiment, a mobile telephone can also be applied. When another person calls, the telephone call detector automatically triggers the detection circuit 21 to alert the holder of the mobile telephone to immediately pick up the telephone and talk.

According to the above-described method, as shown in FIG. 6, the waveform of the transmission pulse is changed or the transmission is stopped for a certain time G, and the transmission pulse is changed to the transmission time F of the normal pulse. The difference can be sensed and a warning effect can be achieved.

According to the above configuration, the pulse clock
Depending on the control (time is calculated in microseconds), the use time of the alarm device can be effectively extended,
Power consumption can also be reduced. In addition, the receiver unit and the transmitter unit can be easily carried by the user, and 1
Since one receiver unit can cooperate with multiple transmitter units simultaneously, functions such as personal care, emergency rescue, and telephone call detection can be achieved.

The embodiments described above are merely illustrative of the present invention, and the scope of the present invention should not be limited to these embodiments. Any modifications and changes derived from this embodiment fall within the scope of the present invention.

As described above, according to the present invention, there is provided one receiver unit and at least one transmitter unit cooperating with the receiver unit, and the transmitter units are simply arranged at regular time intervals. One pulse signal is transmitted, and the receiver unit automatically receives the pulse signal of the transmitter unit, so that the receiver unit stops transmitting the signal while the receiver unit stops transmitting the signal. The receiving circuit of the unit closes synchronously and the receiving circuit is opened again to receive a signal from the transmitter unit before the next transmission pulse is generated. If the receiving circuit fails to receive the transmission pulse signal once or continuously several times, the receiver unit warns the receiver unit holder by voice or vibration.

The transmitter unit can also detect signals from other appliances (such as mobile phones, etc.) and can be controlled by buttons that can change the waveform of the transmitter unit's transmitted wave. Or alternatively,
It can also stop transmitting signals to the transmitter unit, so that the receiver unit can generate sound or vibration to alert the holder of the receiver unit. .

Further, a plurality of transmitter units can be connected to one
