Description

Home wireless alarm

The present invention relates to a home alarm, and more particularly, to a home wireless alarm in which the signal transmission of the main body and the sensor is wireless.

Conventional home alarm is installed by connecting the sensor and the main body to detect the external intruder. Such a home alarm is difficult for the general public to install, and has a disadvantage in that a connection line between a sensor and a main body is found by an intruder.

Home wireless alarm that solves these shortcomings, the wireless sensor device and the main body, the main body is composed of AM receiver, telephone circuit and control unit. When the wireless sensor device detects an external invader, the alarm signal is modulated into an AM signal and transmitted to the main body. The AM receiving unit of the main body demodulates the modulated alarm signal and provides the signal to the control unit, and the control unit processes the signal. Generate an alarm sound or contact the preset telephone number through the telephone circuit unit.

Such a home wireless alarm has the advantage that the sensor and the main body are connected wirelessly and can be easily installed by the general public.However, in case of an emergency, the user or the guard is unable to hear the alarm and cannot take any action. Or, if the security company is far away from the fast action is difficult, in particular, if the intruder breaks out the telephone line to the outside has a disadvantage that the action is not possible.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a home wireless alarm that can receive an alarm signal wirelessly from the outside.

Wireless alarm according to the present invention for achieving the above object is a main body consisting of a first receiver, a first transmitter, a first input unit, an alarm generator, a telephone circuit unit and a first control unit, a second receiver, a second transmitter, A remote control comprising a second input unit, a signal sound generating unit, a display unit and a second control unit, and a wireless sensor device comprising a third transmitting unit and a sensor unit. The first transmitting unit of the main body and the second receiving unit of the remote control are each composed of an FM transmitting circuit and an FM receiving circuit.

When the sensor unit of the wireless sensor device detects the intruder, the third transmitter is switched from the off state to the on state, and the third transmitter modulates the alarm signal into an AM-type radio frequency signal and wirelessly transmits it to the main body. The first receiving unit of the main body demodulates the alarm signal and provides it to the first control unit. The first control unit analyzes the signal and transmits the telephone number or the beep number set by the first input unit to the telephone circuit unit. The number is automatically contacted. In addition, the first transmitting unit of the main body receives the alarm signal by the first control unit and modulates the signal in an FM manner and wirelessly transmits the signal to the remote controller. The second receiving unit of the remote controller demodulates this signal and provides it to the second control unit. The second control unit transmits this signal to the beep generator and the display unit to generate an alarm signal.

The home wireless alarm according to the present invention solves various problems caused when notifying the outside by the wired method only because the alarm signal is notified to the outside by the wireless and wired methods, and other arbitrary places requiring security besides the home alarm.

The first input unit 13 receives a telephone number or alarm release and alarm setting of the main body, and the first control unit 11 receives signals from the first receiving unit 12 and the first input unit 13. The signal is processed to apply an output signal to the first transmitter 14, the alarm sound generator 15 and the telephone circuit unit 16. In this case, the transmission frequency of the first transmitter 14 is selected as a frequency at which interference does not occur with other FM radio frequency signals. In addition, the main body can also be used as a normal telephone.

As shown in FIG. 2B, the remote controller 20 includes a second transmitter 24, a second receiver 22, a second controller 21, a second input unit 23, a signal tone generator 25, and a display unit 26. ), And the second receiver 22 includes a high frequency demodulation circuit capable of receiving the FM signal transmitted from the main body 10 at a distance of 1 km, and the second transmitter 24 includes the main body 10. It is composed of a circuit for modulating the signal for controlling the status check, alarm setting and alarm clearing of the system by AM method. For the excellent transmission function of the remote controller 20, it is also possible for the second transmitter 24 to be configured as an FM transmitter circuit, in which case the first receiver 12 of the main body 10 should be an FM receiver circuit. . The second input unit 23 receives commands such as alarm release and alarm setting of the main body 10, and the signal sound generating unit 25 has a function of generating a beep when receiving an alarm signal from the main body 10, The display unit 26 is composed of display elements such as light emitting diodes and has a function of visually informing an alarm signal.
