Description

Anti-robbing box bag warning device

The utility model relates to a kind of wireless transmit and receiving trap control warning device of utilizing.The various warning devices of selling in the present city, be equipped with a special hand switch as portable multifunctional radio alarming safety cabinet (Chinese patent 96201332), multifunction wireless warning device (Chinese patent 96201661), sensor alarming antitheft door (Chinese patent 95211562) and open or close warning system, then be in the warning state of alert as long as open alarm switch.As portable multifunctional radio alarming safety cabinet, a very important person near or touch safety cabinet and then report to the police.This brings inconvenience to the user, changes existing wireless transmit and receiving trap into remote-control transmitting and receiving trap so designed thief-proof warning suitcase (Chinese patent 96212494), with being switched on or switched off of remote-control transmitting and receiving trap control warning device power supply.The shortcoming of the method for this control warning device power connection or disconnection is the back receiving trap stop work of cutting off the electricity supply.

The purpose of this utility model is a kind of anti-robbing box bag warning device of design, with being switched on or switched off of remote-control transmitting and receiving trap control alarm, promptly connects audible alarm or removes audible alarm.Below remote-control transmitting and receiving trap are called telepilot and receiver.

The utility model is achieved in that this device is made up of telepilot and warning box, and receiver and alarm are arranged in the box of wherein reporting to the police.The warning box is placed in the case and bag, after the energized, and receiver operation.When case and bag left the telepilot certain distance, receiver can not receive the signal of telepilot, and alarm is connected, the warning of sounding.Telepilot and receiver use the circuit in the thief-proof warning suitcase (Chinese patent 96212494).

Below in conjunction with accompanying drawing and example the utility model is described.

Fig. 1. anti-robbing box bag warning device circuit block diagram.

Fig. 2. the circuit theory diagrams of telepilot.

Fig. 3. the circuit theory diagrams of receiver.

Fig. 4. warning box structural representation.

Fig. 5. telepilot profile synoptic diagram.

Referring to Fig. 1, a kind of anti-robbing box bag warning device, comprise telepilot 1 and warning box 2, wherein reporting to the police has receiver 3, alarm 4, alarm switch 5, power supply 6 and power switch 7 in the box, telepilot comprises scrambler and self-excited oscillator, and receiver comprises Armstrong circuit, amplification and rectification circuit, demoder, phase inverter and pilot relay J ₁Form, pilot relay J1 contact J1-2 is connected with LED through resistance R 15, another termination power cathode of LED, the contact J1-1 that it is characterized in that pilot relay J1 is serially connected between alarm switch 5 and the alarm 4, another termination power switch 7 of alarm 4, the other end of alarm switch 5 and power supply 6 join, another termination power 6 of power switch 7.Connect voltage stabilizing diode WD and LED, another termination coded set of WD becomes 18 pin of piece, another termination power cathode of LED.Receiver comprises Armstrong circuit, amplification and rectification circuit, demoder, phase inverter and pilot relay J ₁, in fact Armstrong circuit gets the receiving unit of superregenerative receiver, and it is by R ₅～R ₇, C ₇～C ₁₂, D ₁, L ₂, L ₃And BG ₂Form, receive frequency is by L ₃, C ₇Determine.The coded signal that demodulates is through C ₁₃Be coupled to the amplifier shaping circuit.Amplification and rectification circuit is by R ₁₀～R ₁₂, C ₁₄～C ₁₆, BG ₃And IC ₃Form IC ₃Be the operational amplifier integrated package, play shaping operation at this.Coded signal is through BG ₃Amplification, IC ₃Deliver to decoding integrated package control end IC after the shaping ₂14 pin.At this moment, if signal and demoder coding is identical, IC then ₂17 pin output high level.IC ₂Output terminal through diode D ₂With phase inverter input resistance R ₁₄Connect.Phase inverter is by R ₁₄, D ₃, C ₁₁And BG ₄Form relay J ₁Be the phase inverter load.When pressing self-lock switch K ₁, this moment, a modulated carriers signal was sent in telepilot work, and receiver receives that this modulated carriers signal is through amplifying shaping, if this decoding signals IC ₂Coding and scrambler IC ₁It is identical to encode, then IC ₂Output terminal 17 pin are high level, make BG ₄Conducting, relay J ₁Adhesive.

Referring to Fig. 4, warning box 2 is tubular boxes, is made up of base 8 and loam cake 9, and receiver 3 is installed on the circuit board 10, and circuit board 10 is fixed on the base 8, and alarm 4 is placed on an end of base 8, and the other end of base 8 is placed with power supply 6, base 8 and loam cake 9 snappings.Power supply uses No. 5 batteries.

During use, first energized switch makes receiver operation.Connect alarm switch again, the alarm warning of sounding this moment.Press the self-lock switch K on the telepilot ₁, a modulated carriers signal is sent in telepilot work this moment, and receiver is received this modulated carriers signal, makes relay J ₁Audible alarm is cut off in adhesive.Lose if someone seizes suitcase by force or is not intended to, as long as suitcase is when leaving owner's certain distance, receiver can not receive the signal of telepilot, and alarm is switched on again, the warning of sounding at once.Alarm can be that loudspeaker are reported to the police, and also can be audio alert.

The utility model is simple in structure, dependable performance.
