Abstract
The utility model aims to provide a wireless monitoring and theft-preventing device for a suitcase and a backpack under the system control and with ATmega 16 as a core controller, so that the effect of remote monitoring and theft-preventing is achieved. A pressure sensor is used for detecting the interior weight of the suitcase and the backpack, a Hall sensor is used for detecting opening and closing of the opening of the suitcase and the opening of the backpack, and therefore theft-preventing measures are complete. Meanwhile, an nRF2401 wireless communication module is utilized for carrying out data wireless transmission, so that the device is convenient to use and the effect of detecting external signals at any time is achieved. When information changes, an alarm is given, and therefore the device is safe to use.
Description
Technical field
The utility model relates to the anti-theft device with radio monitoring of a kind of case and bag, knapsack, specifically by main control chip controller monitoring case and bag and knapsack, reaches anti-theft effect.
Background technology
Day by day frequent along with people trip, unavoidable carrying noble, and be exactly as if eternal worry for the protection of these things.Even our the antitheft bag of solution for problems, for current existing antitheft bag, its defect mainly concentrates on antitheft incomplete, can only prevent part case and bag, knapsack stealing, and anti-theft circuit complexity, power consumption is large, not portative aspect, and this has seriously limited the applicability of antitheft knapsack.
Summary of the invention
The purpose of this utility model is to provide under system is controlled, and a kind of case and bag that the ATmega16 of take is core controller, the anti-theft device with radio monitoring of knapsack, reach the remote monitoring, antitheft effect.
The utility model comprises following technical scheme:
The anti-theft device with radio monitoring of a kind of case and bag, knapsack, this device is by main control chip controller monitoring case and bag and knapsack, and adopts pressure sensor is connected with main control chip with Hall element; Be provided with alarm and nRF2401 wireless telecommunications transmitter on main control chip.
Described device also comprises main control chip, is provided with alarm, nRF2401 wireless communication receiver and alarm threshold value device on main control chip.
Described alarm threshold value device gathers the data of pressure sensor and Hall element as alarm threshold value.
Described main control chip is singlechip chip, and its model is ATmega16.
The utility model has the advantage of:
(1) pressure sensor detects case and bag, inside backpacks weight, and Hall element detects bag mouthful switch, antitheft more complete;
(2) utilize the nRF2401 wireless communication module, carrying out the data wireless biography needs, and device is used more convenient;
(3) take the anti-theft device that ATmega16 is controller, reach and detect constantly outer signals, when information changes, providing reports to the police uses more device to feel at ease.

The specific embodiment
The anti-theft device with radio monitoring of a kind of case and bag, knapsack, this device is by main control chip controller monitoring case and bag and knapsack, and pressure sensor 1 is connected with main control chip 3-1 with Hall element 2; Be provided with alarm 4-1 and nRF2401 wireless telecommunications transmitter 5 on main control chip 3-1.
Described device also comprises main control chip 3-2, is provided with alarm 4-2, nRF2401 wireless communication receiver 6 and alarm threshold value device 7 on main control chip 3-2.
Described alarm threshold value device 7 gathers the data of pressure sensor 1 and Hall element 2 as alarm threshold value.
Described main control chip 3-1, main control chip 3-2 is singlechip chip, its model is ATmega16.
Wireless monitor case and bag, knapsack anti-theft device operation principle are as follows:
The anti-theft device with radio monitoring of these case and bag, knapsack is to take a kind of wireless monitor case and bag, the knapsack anti-theft device that the ATmega16 main control chip is core controller.This device adopts pressure sensor detects case and bag, inside backpacks weight, reaches and monitors the purpose whether case and bag, inside backpacks have article to reduce constantly, and Hall element detects a bag mouthful switch, antitheft more complete.The alarm threshold value device can gather the data of current pressure sensor as alarm threshold value, if changing, pressure sensor, Hall element output voltage signal exceed certain threshold value, ATmega16 main control chip controller alarm gives the alarm, just by nRF2401 wireless telecommunications transmitter module, signal is passed to the nRF2401 wireless telecommunications and accept module, thereby ATmega16 controller plc alarm is given the alarm, reach the purpose of remote monitoring.
As shown in Figure 2, nRF2401 wireless communication module circuit diagram as shown in Figure 3 for case and bag, knapsack inner control circuit schematic diagram.The bag controlling system is usingd ATmega16 main control chip controller as control chip, the major function of this system has: the signal of analyzing pressure sensor, Hall element, just make corresponding processing, monitor constantly the situation of case and bag, knapsack, just by the nRF2401 wireless communication module, signal is passed to another ATmega16 controller 7.
The pressure sensor circuit schematic diagram as shown in Figure 4, in order to detect case and bag, inside backpacks weight, reaches and constantly monitors the purpose whether case and bag, inside backpacks have article to reduce, this application of installation pressure sensor.In bag, object reduces, and makes stressed moment variations, and resistance changes.The pressure sensor circuit of this device design, connect a difference channel after stressed moment, make signal become voltage signal, then carry out twice signal amplification with AD620, and its faint variation also can be detected, and increases sensitivity.
As shown in Figure 5, this device has been installed Hall element in case and bag, knapsack mouth one side to the Hall element circuit diagram, and opposite side is installed magnet.Magnetic field changes to the effect of carrier the resistance change that causes Hall element, then this resistance signal is converted to voltage signal.When bag is opened, move the Hall element position, and the magnetic field size that it is subject to changes, thereby the Hall element output voltage changes, and this signal is passed to the ATmega16 controller and process, and makes a response.
