Description

Wisdom campus dormitory safety management system based on RFID and ZigBee technology

Technical field

The utility model relates to RFID and ZigBee technical field, is specifically related to the wisdom campus dormitory safety management system based on RFID and ZIGBEE technology.

Background technology

RF identification is RFID (Radio Frequency Identification; RFID) technology; Claim electronic tag again; Be the communication technology of rising a kind of nineties in 20th century, can discern specific objective and read and write related data, and need not to set up machinery between recognition system and the specific objective or optics contacts through radio signals.The inner integrated circuit of RFID label can drive through the electromagnetic wave that receives CF.When label receives the signal of sufficient intensity, promptly waken up, thereby can be sent data to reader.These data not only comprise (global unique code) ID number, can also comprise preexisting in the data among the EEPROM (electrically erasable read-only memory) in the label.Label can be passive, and the resonance that only depends on electromagnetic wave on resonant circuit, to produce provides WV for circuit; Also can be active, after being waken up,, supply the required voltage of internal circuit to produce external signal through label internal electric source supply.

RFID is considered to influence one of the ten following big technology; Its application prospect very extensively; And many fields have been applied at present, like banknote and product false proof, I.D. and electronic entrance ticket, E-payment system, domestic animal or wild animal identification, patient identification and electronic health record, logistics management, baggage sorting, gate control system etc.

The ZigBee technology is the wireless communication technology of a kind of short distance, low-power consumption, is characterized in closely, low complex degree, self-organization, low-power consumption, low data rate, low cost.Main control and the remote control field automatically of being fit to can embed various device.ZigBee is a kind of highly reliable wireless data sending network, and the ZigBee digital transmission module is similar to the mobile network base station, communication distance from the 75m of standard to hundreds of rice, several kilometers, and support infinite expanding.

At present, there are various potential safety hazards in the campus dormitory because various transgression for using electricity, and many accidents have also taken place, these accidents often occur in evening and dormitory nobody the time, jeopardize personal safety and property safety; Dormitory generation pilferage behavior has then directly caused property loss to the victim.Wisdom campus dormitory safety management system based on RFID and ZigBee technology can help managerial personnel to understand the situation of all electricity consumption products of each dormitory in real time; Dormitory personnel situation; When going wrong, the very first time is notified the victim, at utmost protects the person and property safety.

The utility model content

For solving the deficiency that above-mentioned technology exists; The utility model provides the wisdom campus dormitory safety management system based on RFID and ZigBee technology; Administrative center can gather the situation of certain electricity consumption product of certain dormitory in real time, so that monitor their operating position and position, proactive problem takes place; Native system can be used with wireless entrance guard simultaneously, and the very first time is opened door during breaking out of fire; When the thief occurring, in time lock the door, effectively ensure student's life property safety.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:

Wisdom campus dormitory safety management system based on RFID and ZigBee technology; Comprise sensor assembly, wireless ZigBee module and RFID electronic tag; Said wireless ZigBee module connects said sensor assembly and said RFID electronic tag respectively, and said sensor assembly mainly comprises current-voltage transformer, temperature sensor, smoke transducer and infrared sensor.

The principle of the utility model is:

This system mainly is made up of sensor assembly, wireless ZigBee module and electronic tag.

Sensor assembly mainly comprises current-voltage transformer, temperature sensor, smoke transducer and infrared sensor.Voltage current transformer can be measured the operating position of electricity consumption product in real time, is mainly used in as the dormitory no one, and perhaps after the dormitory people rest in evening, note reminds the student to have which electricity consumption product not close, and supplies their reference; And also can start warning horn when abnormal conditions appear in the electricity consumption product, played prevention effect.Temperature and smog degree in the dormitory are the key factors that judges whether breaking out of fire, send real-time information to administrative center through the temperature in temperature sensor and the smoke transducer timing acquiring dormitory and smog degree and through the ZigBee wireless communication module.When administrative center detect breaking out of fire then infrared ray sensor start automatically, survey in the dormitory whether the student is arranged, so that administrative center's decision-making.

Electronic tag be RFID label and the sensor integrated after, the information that can receiving sensor collects; Itself also has sign; Indicate what product of which dormitory etc., and these information are sent to the ZigBee module, send to network controller by the ZigBee wireless sending module.Can realize navigating to the concrete article of concrete dormitory.

The ZigBee module can realize the location, if certain specific dormitory product leaves original position certain limit like this through the power of wireless signal; Then produce alarm at once; And sending information to administrative center, administrative center's note is reminded the victim, ensures property safety.

The beneficial effect of the utility model is:

The utility model is arrived school RFID technology and ZigBee technical application on the problem of this extensive concern of dormitory safety, can navigate to the specific products of specific dormitory.

The electricity consumption product at first can be monitored according to current-voltage transformer in real time in the personal safety aspect, reminds the student when sleep is perhaps left dormitory, to close the electricity consumption product, has both practiced thrift resource and also can prevent the generation of disaster; And in time notify the victim during dormitory breaking out of fire, and administrative center can take rescue plan according to the information of collecting, and greatly improved student's personal safety.The property aspect can realize the tracking of article through the ZigBee location technology, surpasses then SMS notification victim of certain limit, and produces alarm.The electricity consumption product can interconnected communication, if use traditional wiring communication then to be difficult to realize.

The utility model adopts ZigBee wireless self-networking technology, has avoided loaded down with trivial details wiring, has reduced installation cost; Simultaneously can realize MANET, possess self-healing function, ensure the transmission reliability of the network information.
