Embodiment
Be example with luggage below, the utility model further specified in conjunction with accompanying drawing:
As shown in Figure 1; The described anti-theft device of the utility model comprises the signal transmitter unit 1 that is placed on the luggage and is placed on user's signal receiving unit 2 two parts on one's body; Wherein, Signal transmitter unit 1 comprises power supply (not shown), DF transmitter module 11 and PT2262 coding chip 12, and DF transmitter module 11 is connected with coding chip 12; Signal receiving unit 2 comprises power supply (not shown), DF receiver module 21, PT2272 decoding chip 22, single-chip microcomputer 23, alarm 24 and display screen 25; Single-chip microcomputer 23 is connected with DF receiver module 21, PT2272 decoding chip 22, alarm 24 and display screen 25, and PT2272 decoding chip 22 is connected with DF receiver module 21.
In this anti-theft device, adopted coding chip PT2262, decoding chip PT2272, as long as press & hold always, coding chip PT2262 will transmit continuously, and 2272 chip low in energy consumption, external component is few.
Wireless DF transceiver module needs only with the PT2272 decoding chip with the PT2262 coding chip and directly is connected; Because be the own coding decoding chip; So the fine transmission range of effect is far, because making to transmit, extraneous barrier decays to zero problem with regard to having solved like this.
The signal receiving unit 2 of the said anti-theft device of the utility model also is furnished with keyboard 26.Through keyboard 26, the user can be provided with safe distance according to the environment at place.Single-chip microcomputer 23 can calculate the distance between signal transmitter unit and the signal receiving unit automatically and on display screen 25, show in real time.Distance calculating method between signal transmitter unit and the signal receiving unit is following: the coding chip 12 in the signal transmitter unit 1 is through the high-low level coding of control pin, then through DF transmitter module 11 wireless transmission signal, when DF receiver module 21 is received signal; Decode through decoding chip 22; Pass to single-chip microcomputer 23 then and read, and pick up counting, at this moment signal transmitter unit 1 continues to transmit; When single-chip microcomputer 23 receives several signals; Single-chip microcomputer 23 will calculate the distance between user and the luggage, and with the safe distance of result calculated and setting numerical value compare, if actual range is greater than setpoint distance; Single-chip microcomputer 23 will be controlled alarm equipment alarm; Send the for example audible ringing signal of " luggage exceeds safe distance, please notes ", and data are shown through display screen 25.
Yet the user understands luggage a period of time away from keyboard in some cases, such as by train the time; The user goes to time toilet, when perhaps going boiler to connect glass hot water, at this moment also possibly exceed the safe distance of setting; Alarm will be reported to the police, and in order to prevent the situation of false alarm, on signal transmitter unit 1, also is provided with the Vibration Sensor 13 and photo switches, photo sensors 14 that are connected with coding chip 12; When Vibration Sensor 13 is sensed vibration, can send alerting signal; Photo switches, photo sensors 14 senses when ambient light changes can send alerting signal.
For the false alarm that prevents to jolt and cause because of article; It is preferential that the user can be provided with safe distance through single-chip microcomputer; Even Vibration Sensor senses vibration and/or photo switches, photo sensors and senses light when changing, as long as article are in safe distance, single-chip microcomputer will be controlled alarm and not report to the police; It is preferential that vibration and/or photoelectric alarm also can be set certainly.
In order to prevent that light from brightening along with the colour of sky naturally or during natural deepening; Alarm generation false alarm; As: the described anti-theft device of the utility model has been applied in the electric motor car, when electric motor car be placed on outdoor, the false alarm that causes when preventing noon to follow light at dusk can naturally-occurring to change; The user also can through keyboard to set up in the unit interval changing value of light determine whether to report to the police; The changing value of light has exceeded setting in the unit interval, and at this moment the surrounding environment that article are described by the people for a change just needs to report to the police.
Equally, in order to prevent article normal vibration generation false alarm, the user can determine whether through the number of times of keyboard to set up unit interval internal vibration to report to the police.Such as when belongings were taken train, train wheel all will jolt through the seam crossing of two one steel rails the time, will drive article and vibrate, and this belongs to normal vibration, and single-chip microcomputer just can be controlled alarm and not report to the police; When the article vibration has surpassed the frequency of setting, explain not to be normal vibration that single-chip microcomputer will be controlled alarm equipment alarm, remind the user to check article.
In this anti-theft device, signal receiving unit 2 also comprises a controller 27.The user can be provided with whether open Vibration Sensor and photo switches, photo sensors warning through controller 27.Some user is very careful; The user want in luggage and the distance between it if greater than safe distance the time just start alarm; The user can make the not signal that transmits of respond vibration sensor, photo switches, photo sensors of single-chip microcomputer through controller so; That is to say that as long as the distance between transmitter unit and the receiving element greater than safe distance the time, alarm will be reported to the police.Certainly, the user also can only judge the state of luggage through Vibration Sensor, photo switches, photo sensors, looks user self and need be provided with and get final product.
Be that example is illustrated the utility model just above, but the utility model is not limited to above-mentioned specific embodiment with the luggage antitheft, as: the utility model also can be applicable in the antitheft of article such as electric motor car, motorcycle, automobile, also has extraordinary effect.Therefore, all any changes done based on the utility model or modification all belong to the utility model and require the scope protected.
