Abstract
The said wireless alarm system consists of the transmitter installed in automobile, bank, warehouse, etc. and the receiver carried about by the owner or security personnel. It has the functions of in-site alarm, wireless alarm, remote control of ignitor system and power conversion.
Description
The present invention relates to a kind of wireless sound alarming system.
Use comparatively general alarm at present, all adopt the onsite alarming form, warn with police whistle sound, but require the warning scene at any time the law enforcement officer will be arranged, otherwise can't play the warning effect.
The object of the present invention is to provide a kind of both can be on-the-spot languages type report to the police, the emission that can lean on radiowave is again reported to the police with receiving, and can also change to reach the wireless sound alarming system of security purpose by remote circuit.
The present invention is made up of transmitter and receiver, is divided into three parts.Be radiating portion, receiving unit and power source conversion remote control part.Radiating portion is made up of sensing circuit, signaling conversion circuit, language generation circuit, radiating circuit and encrypted circuit, is assemblied in the transmitter; Receiving unit is made up of receiving circuit, decrypt circuit and pronunciation circuit, is assemblied in the receiver; The power source conversion remote control partly is that power supply remote-control receiving circuit and power-switching circuit are housed in transmitter, and the power supply remote controlled transmitting circuit is housed in receiver; Wherein radiating circuit, receiving circuit and pronunciation circuit can be made integrated circuit, with reduced volume; Transmitter is installed in the place that automobile, bank or warehouse etc. need warning, on one's body receiver is worn on by car owner or law enforcement officer.After the sensing circuit on the transmitter receives signal, after signaling conversion circuit forwards language generation circuit to, produce the two-way speech signal, the one tunnel changes radiowave into through radiating circuit, launches after encryption circuit encrypts; Another road is directly amplified by language generation circuit, onsite alarming.After the receiving circuit of receiver is received signal, decipher through decrypt circuit, change sound signal again into, by the pronunciation circuit sounding power source conversion remote control part of warning, send infrared ray by the power supply remote controlled transmitting circuit in the receiver, after power supply remote-control receiving circuit in the transmitter received signal, the control power-switching circuit reached purpose of safety.
The invention has the advantages that highly sensitively, volume is little, and it is various informative, convenient and reliable to report to the police.

The present invention is described in further details with most preferred embodiment below in conjunction with accompanying drawing:
The present invention is made up of transmitter and receiver, is divided into three parts.Be radiating portion, receiving unit and power source conversion remote control part, radiating portion is by sensing circuit (1), signaling conversion circuit (2), language generation circuit (3), and radiating circuit (4) and encrypted circuit (5) are formed, and are assemblied in the transmitter; Receiving unit is made up of receiving circuit (8), decrypt circuit (9) and pronunciation circuit (10), is assemblied in the receiver; The power source conversion remote control partly is that power supply remote-control receiving circuit (7) and power-switching circuit (6) are housed in transmitter, and power supply remote controlled transmitting circuit (11) is housed in receiver; Wherein radiating circuit (4), receiving circuit (8) and pronunciation circuit (10) can be made integrated circuit, with reduced volume; Transmitter is installed in the place that automobile, bank or warehouse etc. need warning, on one's body receiver is worn on by car owner or law enforcement officer.After the sensing circuit on the transmitter (1) receives signal, after signaling conversion circuit (2) forwards language generation circuit (3) to, the two-way speech signal that produces, the one tunnel changes radiowave into through radiating circuit (4), encrypts the back through encrypted circuit (5) and launches; Another road is directly amplified by language generation circuit (3), onsite alarming.After the receiving circuit (8) of receiver is received signal, through decrypt circuit (9) deciphering, change sound signal again into, warn by pronunciation circuit (10) sounding.Power source conversion remote control part is sent infrared ray by the power supply remote controlled transmitting circuit (11) in the receiver, and after the power supply remote-control receiving circuit (7) in the transmitter received signal, control power-switching circuit (6) reached purpose of safety.
Claims (2)
1, a kind of wireless sound alarming system is characterized in that it is made up of transmitter and receiver, is divided into radiating portion, receiving unit and power source conversion remote control part.Radiating portion is made up of sensing circuit (1), signaling conversion circuit (2), language generation circuit (3), radiating circuit (4) and encrypted circuit (5), is assemblied in the transmitter; Receiving unit is made up of receiving circuit (8), decrypt circuit (9) and pronunciation circuit (10), is assemblied in the receiver; The power source conversion remote control partly is that power supply remote-control receiving circuit (7) and power-switching circuit (6) are housed in transmitter, and power supply remote controlled transmitting circuit (11) is housed in receiver.After the sensing circuit on the transmitter (1) receives signal, after signaling conversion circuit (2) forwards language generation circuit (3) to, produce the two-way speech signal, one the tunnel changes radiowave into through radiating circuit (4), behind encrypted circuit (5) encrypted circuit, launch, another road is directly amplified by language generation circuit (3), onsite alarming.After the receiving circuit (8) of receiver is received signal, change sound signal again into through decrypt circuit (9) deciphering, warn by pronunciation circuit (10) sounding.Power source conversion remote control part is sent infrared ray by the power supply remote controlled transmitting circuit (11) in the receiver, controls power-switching circuit (6) conversion electric power after the power supply remote-control receiving circuit (7) in the transmitter receives signal.
2, a kind of wireless sound alarming system as claimed in claim 1 is characterized in that described radiating circuit (4), receiving circuit (8) and pronunciation circuit (10) are respectively integrated circuit.
