Embodiment
Describe the utility model electronic anti-theft apparatus in detail below in conjunction with accompanying drawing and specific embodiment.
In conjunction with the accompanying drawings 1 with the line principle of accompanying drawing 2 explanation the utility model electronic anti-theft apparatus.The utility model electronic anti-theft apparatus comprises transmitter and receiver.Transmitter is used to send radiofrequency signal, and receiver is used to receive the radiofrequency signal that transmitter sends.As Fig. 1, transmitter comprises the coding module 101 that produces coded signal, be used for that the coded digital signal that coding module 101 produces is modulated to the radio-frequency module 102 launch on the radiofrequency signal and to the battery 103 of above-mentioned two module for power supply.
As Fig. 2, receiver in the utility model electronic anti-theft apparatus comprise the radio-frequency module 201 of received RF signal, to the received signal carry out shaping and amplifying signal amplification module 202, be used for receiving and carrying out decoding module 203 through the digital signal of processing and amplifying, be connected the key-press module 204 that is used to control, be provided with the receiver operation state with decoder module 203, and same buzzing module 205 and/or the electromagnetic shaker 206 that is used to respond loss, reminds the user that be connected with decoder module.In other words, because distance is when zooming out the signal that can not receive transmitter emission, hummer 205 will sounding when receiver, and perhaps electromagnetic shaker 206 will vibrate, and reminds article lost or child to walk far.
Fig. 3 has provided the circuit theory diagrams of the transmitter of the utility model electronic anti-theft apparatus.As shown in Figure 3, the radio-frequency module 102 among Fig. 1 comprises triode Q1, Q2 among Fig. 3 and resistance R 1, capacitor C 1-C4, crystal oscillator Y etc., is used for by the radiofrequency signal of antenna ANT emission through coding; Wherein, the generation radio-frequency module output signal of triode Q1 base stage is connected with coding module by resistance R 3, coding module 101 among Fig. 1 comprises among Fig. 3 coding chip U1 and the button that is connected with coding chip and peripheral resistance, capacity cell etc., is mainly used in the coded signal of setting between transmitter, the receiver.Battery BAT is connected to each module by switch S 1 among Fig. 3.
Fig. 4 has provided the circuit theory diagrams of the receiver of the utility model electronic anti-theft apparatus.As shown in Figure 4, the radio-frequency module 201 among Fig. 2 is made of the radio-frequency (RF) receiving circuit of standard triode Q1 and Q2 and other capacitance resistances in Fig. 4, is used to receive the radiofrequency signal of transmitter emission; Signal amplification module 202 among Fig. 2 is made of a plurality of phase inverter U2F, U2E, U2D, U2A and other capacitance resistances in Fig. 4, is used for the signal that receives is amplified shaping; Decoder module 203 among Fig. 2 is that model is the decoding chip U3 of LP856-02 in Fig. 4, is used for deciphering receiving through signal processing and amplifying signal; Among Fig. 4, receiver also is provided with the button toggle switch, is used to regulate receiver sensitivity; Receiver also comprises the low voltage detecting module that triode Q4 constitutes, and is used to detect the voltage of received signal, and when being lower than ratings, promptly transmitter, receiver spacing exceed preset distance, thereby realizes reporting to the police; Receiver also comprises the simultaneous switching circuit that is made of Q3, and when receiving signal, other circuit such as decoder module are power supply synchronization, guarantees receiver saving electricity consumption; Comprise also among Fig. 4 that the buzz circuit that is made of triode Q5, microphone device LS1 corresponding to the hummer among Fig. 2 205, is used for early warning; (do not indicate vibration module among the figure, usually, vibration module can select for use the eccentric motor circuit to realize and connect in the vibrating device branch road that resistance R 22 connects in the drawings.
The transmitter portion of the utility model electronic anti-theft apparatus can be installed on the mobile phone, in the wallet, leather trunk or to be contained in young child anti-lost in advance, the receiving unit of electronic anti-theft apparatus allows monitoring child's adult or the owner who easily loses article carry.Its principle of work is, transmitter (handset) places on one's body valuables or the children, and receiver (machine tool) places on one's body the user.With the transmitter power switch opens, the signal lamp flicker, transmitter intermittently sends the regular coding signal, and the handset that sends signal is placed on by the machine tool, and the machine tool switch is pushed study place, machine tool sends the start prompting sound, then send the study prompting sound, at this moment, machine tool is learnt the coding of current handset, signal lamp is by the long bright flicker that transfers to, and learning functionality is finished.Then, if receiver can correctly receive the coded signal of transmitter, receiver standby in the certain hour section; If receiver can't receive signal, then send the alarm sound, be monitored object away from the overseer to show.The distance of this received signal is a 0.5--8 rice, that is to say, when the distance of transmitter and receiver surpasses this predetermined distance, in other words, distance between transmitter and the user receiver (machine tool) on one's body surpasses setpoint distance, and receiver will send rapid chimes of doom.This distance can suitably be regulated as required.The utility model electronic anti-theft apparatus also has the searching function, behind the valuable goods loss that carries handset, presses the searching key, the machine tool motor vibrations, and when losing the article certain distance, motor stops vibration, sends proximity sensing sound, and convenient the searching lost article.
