With reference to accompanying drawing 2.The demoder of anti-theft device for commodities provided by the utility model, the wireless signal transmission circuit 900 that it is provided with second microprocessor 800 and is connected with second microprocessor, described wireless signal are to make electronic article surveillance tag thing 301 that the decoding wireless signal of induction take place.Microprocessor 800 can adopt single-chip microcomputer.
After circuit was connected, single-chip microcomputer work produced the code signal of certain frequency, after amplifying through power amplification circuit, was outwards sent by antenna.In the present embodiment, the described wireless signal transmission circuit that is connected with second microprocessor is the high-frequency wireless signals radiating circuit.
Businessman can make demoder fixed equipment and be arranged on cashier in use, when customer payment, with electronic article surveillance tag thing process demoder, perhaps demoder is transmitted to the electronic article surveillance tag thing, anti-theft device is decoded, the electronic article surveillance tag thing receives decoded signal and responds to the signal that corresponding frequencies is exported in the back, amplify through circuit 200, detect by single-chip microcomputer, and then unblank with the removal anti-theft device with the magnetic lockaid gun, demoder also can be made handheld device, so that the batch goods is once decoded.Above-mentioned anti-theft device for commodities and demoder have been formed the anti-theft device for commodities system, and businessman is when being equipped with, and demoder can be a plurality of according to operating personnel's quantity, and anti-theft device for commodities is put quantity also for a plurality of according to commodity.
Theft preventing method below in conjunction with 3 pairs of anti-theft devices provided by the utility model of accompanying drawing is further described:
When being in user mode; power supply in the circuit board is connected all the time; the two ends of metal anti-theft rope 1 are connected with tie point 401,402; insert antitheft nail; the contact of switch 601 is depressed, and circuit 600 is connected, and reed switch 504 is squeezed by shank 20 and opens simultaneously; circuit 500 is in off-state, and single-chip microcomputer 100 is judged as anti-theft device and enters guard mode at this moment.
The signal of a, first microprocessor detected electrons article surveillance label induced signal output circuit, judge that this signal is:
1), the electronic article surveillance tag thing receives decoded signal and responds to the signal of back output,
Still; 2), the electronic article surveillance tag thing receives the signal of control door antenna transmission and responds to the signal of rear output; The control door of above indication be exactly the management place set prevent the outpost of the tax office that commodity are stolen; Which is provided with signal transmission circuit; Pass through control door through out-of-date when commodity are stolen; Electronic article surveillance tag thing in the anti-theft device on the commodity to the induced signal of control door signal also can monitored door receiving circuit receive; The device by the instruction of control door institute that makes control door or be located at other place sends alarm signal
Or, 3), the signal exported when the electronic article surveillance tag thing does not receive the signal of decoded signal and control door antenna emission,
Respond to the signal that export the back as detected signal for the signal that the electronic article surveillance tag thing receives the emission of control door antenna, represent that then commodity are stolen, by the amplifying circuit amplifying signal intensity in the circuit 300, be judged as the signal that meets predeterminated frequency via single-chip microcomputer 100, booster circuit boosted voltage in the phonation circuit drives hummer then and sounds.
B, first microprocessor detect secondary signal generation circuit, the 3rd signal generating circuit, the 4th signal generating circuit that is connected, and judge:
Whether secondary signal generation circuit has the metal anti-theft rope to disconnect pairing signal, whether the 3rd signal generating circuit has the nail bar to break away from the pairing signal of the 3rd signal generating circuit, whether the 4th signal generating circuit has described switch to be disengaged the pairing signal of compressing, in the present embodiment, these signals are high-frequency signal;
C, do not detect signal described in the b, then do not send the signal instruction that makes sounding alarm circuit sounding alarm as first microprocessor;
D, detect the arbitrary signal described in the b as first microprocessor, and first microprocessor detects the signal of signal for exporting after responding to because of electronic article surveillance tag thing reception decoded signal that first signal generating circuit takes place, and first microprocessor does not still send the signal instruction that makes sounding alarm circuit sounding alarm;
E, detect the arbitrary signal described in the b as first microprocessor, and it is the signal that the electronic article surveillance tag thing is exported when not receiving decoded signal that first microprocessor detects signal that first signal generating circuit takes place, and first microprocessor sends signal instruction and makes sounding alarm circuit sounding alarm.
Also promptly:
When the metal anti-theft rope was cut off, circuit 400 passed to high-frequency signal of single-chip microcomputer immediately, and single-chip microcomputer is judged as destructive alerting signal, and the booster circuit boosted voltage in the phonation circuit drives hummer then and sounds.
When sledge plays the head of a nail or otherwise makes the contact of switch 601 stretch out, switch 601 is an open mode, then circuit 600 is started working, transmit a high-frequency signal and give single-chip microcomputer, single-chip microcomputer is judged as destructive alerting signal, booster circuit boosted voltage in the phonation circuit drives hummer then and sounds.
When antitheft nail is directly extracted, reed switch 504 closures then, no matter whether switch 601 is opened or closure, circuit 500 is all started working, pass to high-frequency signal of single-chip microcomputer simultaneously, single-chip microcomputer is judged as destructive alerting signal, and the booster circuit boosted voltage in the phonation circuit drives hummer then and sounds.
Described step a comprises that also whether the output circuit of the electronic article surveillance tag thing induced signal that the first microprocessor detection is connected has signal, as no signal, sends signal instruction and makes sounding alarm circuit sounding alarm.
