Middle radiating portion (3) is near radiating portion (1), usually in 30 meters scopes.For example radiating portion (1) is placed in the metal safety cabinet, radiating portion (3) can be arranged in this safety cabinet room or non-shielding place of adjacent rooms then, it can be placed in the where there is light, but preferably is placed in the dark place, as in the wooden desk or in the wooden bookcase etc.Circuit such as Fig. 4 of middle radiating portion (3), it can be identical with the circuit of radiating portion (1), all can be by remote-control receiving circuit, the vibrating sensing circuit, driving circuit and radiating circuit are formed, middle receiving circuit in the middle of just the remote-control receiving circuit in the radiating portion (1) is in the radiating portion (3), the former radiating circuit is the latter's middle radiating circuit, and the receiving antenna of middle receiving circuit is TX4, it not only receives transmitting of the middle radiating circuit of radiating portion (1), receive transmitting of remote control transmitter simultaneously, and draw single line again at its decoding circuit data terminal and directly link to each other with the input of driving circuit, middle radiating circuit work in the middle of can directly making after the carrier signal that makes radiating portion (1) send from emitting antenna TX3 is received by the receiving antenna TX4 of middle radiating portion (3) the radiating portion (3), the emitting antenna TX5 from middle radiating circuit sends alerting signal at last.
The utility model receiving unit (2) and middle radiating portion (3) apart from each other, greatly in 300 meters scopes, usually receiving unit (2) is arranged on entrance guard chamber or security department, each receiving unit (2) can be corresponding one by one with radiating portion (3) in the middle of each, in case a certain receiving unit (2) sends alerting signal, then security department knows that with regard to standing this situation appears in which department, also but receiving unit (2) is only with one, it comes to match with radiating portion (3) in the middle of each by the single-chip microcomputer decoding, accomplish a tractor serves several purposes, and can demonstrate alarm set point by the display part.Circuit instance graph such as Fig. 5 of receiving unit (2), it is by Armstrong circuit, amplifying circuit, shaping circuit, decoding circuit and warning circuit are formed, wherein Armstrong circuit is by receiving antenna TX6, inductance L 8, L9, resistance R 22-R26, capacitor C 19-C24, diode D5, transistor T 7 constitutes, amplifying circuit is by transistor T 8, capacitor C 25, resistance R 27, R28 constitutes, shaping circuit is by amplifier IC10, resistance R 29 and capacitor C 26 constitute, and decoding circuit is made of decoding integrated package IC9 (model can be YH27) and diode D6, and warning circuit is by transistor T 9, resistance R 31, loudspeaker S1 forms.
During the utility model work, radiating portion (1) is positioned at metal safety cabinet or the stronger room of shielding, if will be in the warning duty, can press the remote control buttons K of remote control transmitter, it has connected the power supply of coding integrated package IC1, IC1 work is sent a group coding signal and is made the strength circuit working by inductance L 1, just launches a group coding remote signal from the emitting antenna TX1 of remote control transmitter.This remote signal is launched the receiving antenna IX2 of remote-control receiving circuit in the part (1) and the receiving antenna TX4 of the middle middle receiving circuit of middle radiating portion (3) receives simultaneously, here receiving circuit has the function of remote-control receiving circuit concurrently in the middle of, when in case remote control transmitter sends remote signal, the antenna TX4 of the antenna TX2 of radiating portion (1) and middle radiating portion (3) receives remote signal simultaneously, makes radiating portion (1) and all in running order or closed condition of middle radiating portion (3).
After coded telecommand signal that remote control transmitter sends is launched Armstrong circuit reception in part (1) remote-control receiving circuit and amplifying circuit, shaping circuit to amplify shaping, obtain the input that a high-level control signal is delivered to Sheffer stroke gate IC4 after by decoding circuit IC3 decoding, make the vibrating sensing circuit energized of radiating portion (1) in running order.The vibrating sensing circuit of radiating portion (3) is in running order in the middle of in like manner also making.
At this moment, in case radiating portion (1) has abnormal conditions, then piezoelectric patches G1 has vibration signal, so send one group of high level signal from amplifier IC7 output terminal, make driving circuit T4, T5 conducting work, then coding circuit IC8 sends a group coding signal, the strength circuit oscillation of this coded signal in radiating portion (1) radiating circuit sends carrier signal from emitting antenna TX3, though signal weakening after this carrier signal conductively-closed, can't be received part (2) receives, but still can be received by near the receiving circuit of radiating portion (3) in the middle of, because middle receiving circuit draws single line in addition and links to each other with the driving circuit input, the middle radiating circuit work of radiating portion (3) in the middle of then the carrier signal that is received by the receiving antenna TX4 of middle radiating portion (3) can directly make, TX5 sends alerting signal from its emitting antenna.Receiving antenna TX6 and Armstrong circuit T7 that this alerting signal is received part (2) receive, and through amplifying circuit T8 and shaping circuit amplification shaping, again by just triggering warning circuit T9 work after the decoding circuit IC9 decoding, S1 sends alerting signal from loudspeaker, make and security department in time recognize certain safety cabinet or storehouse there is something special, can take urgent emergency measure.
Radiating portion (3) in the middle of of the present utility model is owing to also be provided with the vibrating sensing circuit, then it is simultaneously in running order, like this when the burglar does not also bump safety cabinet, as long as bumped earlier near the middle radiating portion (3) it, then its piezoelectric ceramic piece G2 just exports vibration signal, send alerting signal from its emitting antenna TX5 equally, send alarm sound for receiving unit (2) reception and by loudspeaker S1.Thereby increased an alarm set point more.
If the utility model can adopt same principle to finish with the multichannel trunking scheme when requiring alarm range bigger.
