Abstract
The utility model relates to a wireless anti-theft alarming system which comprises an emitter circuit system and a receiving alarm system, wherein the emitter circuit system comprises an LC oscillation circuit, a wireless transmitter and a power supply, the LC oscillation circuit is connected with the wireless transmitter, the emitter circuit system is installed on a protected object, the receiving alarm system comprises a wireless receiver, a signal checker, a single chip microcomputer, a sound and light alarm, a control keyboard and a power supply, the wireless receiver is connected with the single chip microcomputer through the signal checker, and the sound and light alarm and the operation control keyboard are directly connected with the single chip microcomputer. The wireless anti-theft alarming system adopts the wireless monitoring mode for preventing theft, judges whether the protected object is stolen or not through checking the frequency and the intensity of the electromagnetic waves sent from the protected object, and if the projected object is stolen, sound and light alarm can be sent immediately to prompt masters to pursue back.
Description
Technical field:
The utility model relates to a kind of electronic anti-theft warning system, especially a kind of wireless burglar alarm system.
Background technology:
Some valuable light little instrument and equipments (as notebook computer, mobile phone etc.) are urinated stolen easily in carrying because of its volume.Stolen after deliberation reason finds, these instrument and equipments or need not lock, or just with Steel wire rope lock on indoor tables and chairs.Next antitheft with wire rope, seem firm, if with combination pliers it is cut off, instrument and equipment still can be stolen.And after locking wire rope, when thinking mobile instrument and equipment, all must unblank so unusual trouble earlier at every turn.
The utility model content:
The purpose of this utility model just is the deficiency at above-mentioned technology, and a kind of wireless burglar alarm system is provided, and it is antitheft that it adopts the wireless monitor mode, as long as illegal mobile object of protection just may trigger warning, thereby reaches antitheft purpose, and is very easy to use.
The technical solution of the utility model is: a kind of wireless burglar alarm system, and it comprises that an emission circuit system and receives warning system, is characterized in that:
Described emission circuit system, it comprises a LC oscillatory circuit, a wireless launcher, a power supply, described LC oscillatory circuit is connected to wireless launcher; Described emission circuit system is installed on the object of protection;
Described reception warning system, it comprises a wireless receiver, a signal detector, a single-chip microcomputer, an audible-visual annunciator, a manipulation keyboard, a power supply;
Described wireless receiver joins by signal detector and described single-chip microcomputer, and described audible-visual annunciator, manipulation keyboard directly are connected to single-chip microcomputer.
The beneficial effects of the utility model are:
1. the utility model adopts the wireless monitor mode next antitheft, sends electromagnetic frequency and intensity on one's body by the detection object of protection and judges whether it is stolen; Object of protection is just sent sound and light alarm immediately if steal, thereby reminds owner to recover.
2. the utility model design is unique, novel, makes easily.
3. the utility model is simple and practical, cost is low, benefits to promote the use of.
Description of drawings:
Below in conjunction with drawings and Examples further to the utility model explanation.
Fig. 1 is a structured flowchart of the present utility model.
Embodiment:
As shown in Figure 1, a kind of wireless burglar alarm system, it comprises that an emission circuit system and receives warning system;
Described emission circuit system, it comprises a LC oscillatory circuit, a wireless launcher, a power supply, described LC oscillatory circuit is connected to wireless launcher; Described emission circuit system is installed on the object of protection;
Described reception warning system, it comprises a wireless receiver, a signal detector, a single-chip microcomputer, an audible-visual annunciator, a manipulation keyboard, a power supply;
Described wireless receiver joins by signal detector and described single-chip microcomputer, and described audible-visual annunciator, manipulation keyboard directly are connected to single-chip microcomputer;
Described emission circuit system is used to launch the electromagnetic wave of certain frequency and intensity;
Described reception warning system is used to receive electromagnetic wave, and detects its frequency and intensity, thereby judges whether object of protection moves, and whether decision drives warning;
Described single-chip microcomputer is used for data processing, control hardware;
When the described reception warning system of described emission circuit system long distance, the detected electromagnetic intensity of signal detector weakens gradually; When electromagnetic intensity during less than set threshold value, audible-visual annunciator will be driven immediately by single-chip microcomputer, sends warning, thereby realizes antitheft.
