Background technology
With the development of modern society, hold an exhibition also more and more frequently, the security for the article put on display in exhibition room is
Exhibitioner and personal very concern, what exhibition room was put on display is all often more rare object, once stolen, Jiu Huizao
Into huge loss, take that new and high technology means are taken precautions against and the crime that hits out against theft be can yet be regarded as a kind of effective method.Now
Exhibition room monitoring generally has two class methods：(1) direct monitoring type, mainly by shooting of the camera to scene, directly by scene
Picture shows that on a display screen display screen is then monitored for 24 hours by monitoring personnel.This monitor mode has the drawbacks of very big, it
It is required that monitoring personnel at every moment watch screen attentively, it is impossible to there have to be a bit slack, very high to monitoring personnel requirement, antitheft
It is to make provision against emergencies, guarder equally also has contingency situation, just in case leaving, just in case playing drowsiness etc., burglar has once found out situation
Afterwards, and can take advantage of a weak point.(2) infrared monitor control, mainly it is connected by infrared inductor with warning device, when infrared
Line inductor sense ambiguous barriers by when, then connect warning device alarm, this monitor mode has following 2 kinds and be difficult to
Solve the problems, such as：1) relation of sensitivity and rate of false alarm, the height that sensitivity is adjusted, rate of false alarm also improve；Sensitivity is adjusted low, some
When do not alarm；2) current infrared theft device is mostly installed at some fixed positions, such as window and Men Chu, once burglar slaps
Position and the feature of anti-theft device have been held, has avoided this road defence line, infrared monitoring device is just difficult to the row for successfully stopping burglar
Surreptitiously.Publication No. CN101587621A Chinese patent discloses a kind of method and apparatus for monitoring security of exhibition hall, not between
Disconnected compares the image monitored and sample image, sends instruction alarm to warning device if having abnormal conditions, simultaneously
The image photographed is stored in memory.Practical application finds that the method and apparatus of the monitoring security of exhibition hall still have
Alarm the drawbacks such as insensitive, poor reliability, still need to further improve.

When transceiving chip finds to have with receives frequency identical carrier wave, its carrier wave detection (CD) is set to high level；Hereafter, nRF905 is worked as
When radio transmitting and receiving chip receives effective address, address matching (AM) is set to high level；
After this, when nRF905 radio transmitting and receiving chips receive effective address bag (CRC check is correct), nRF905
Radio transmitting and receiving chip will remove lead code, address and CRC bit, while data ready position (DR) is set into high level, be used in combination
It is low level that MCU, which sets TRX-CN, to enter standby patterns, so that singlechip chip circuit MCU can be with suitable speed
Rate reads effective data by SPI interface；After all data read-outs, nRF905 radio transmitting and receiving chips set AM and DR
For low level, so as to make nRF905 radio transmitting and receiving chips be prepared to enter into ShockBurst RX, ShockBurst TX or
Powerdown patterns.
Radio transceiver chip uses but is not limited to nRF905 radio transmitting and receiving chips, is built-in with antenna, while internal collection
Into there is the function such as modulation, demodulation, coding/decoding, therefore lead code and CRC check can be automatically generated in communication process.The present apparatus
The wireless data transceiving system designed according to the characteristics of nRF905 radio transmitting and receiving chips, it was proved that, it can realize short distance
From wireless serial transparent transmission, effective communication distance be more than 200 meters.Surveyed in the building for the concrete structure for there are obstructing objects
Examination, its effective line communication distance are more than 50m.
It should be understood that although with reference to its exemplary embodiment, particularly shown and description is carried out to the present invention,
It should be understood by those skilled in the art that without departing substantially from by spirit of the invention as defined in the claims and model
Under conditions of enclosing, the change of various forms and details can be carried out wherein, can carry out any combination of various embodiments.
