Description

A kind of wireless entrance guard controller based on technology of Internet of things

Technical field

The utility model relates to the ZigBee field, is specifically related to a kind of wireless entrance guard controller based on technology of Internet of things.

Background technology

ZigBee is the synonym of IEEE 802.15.4 agreement.Technology according to this agreement regulation is the wireless communication technology of a kind of short distance, low-power consumption.Be characterized in closely, low complex degree, self-organization, low-power consumption, low data rate, low cost.Summary of the invention mainly is suitable for control and remote control field automatically, can embed various device.In brief, ZigBee is exactly a kind of cheap, the near radio networking mechanics of communication of low-power consumption.

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.

In fact, gate control system has become developed country and regional topmost security device, and is different with traditional security device, and it becomes passive monitoring and reports to the police to control initiatively, has played higher safety effect.Therefore, gate control system is leading in the security device field day by day, and according to the investigation statistics result of U.S. authoritative institution: the nineties, U.S. gate inhibition device sales volume accounted for 57 of whole public safety industry market sales volume.8%; Closed-circuit control and other panalarm total sales only account for 39.2%; In addition, in the report of safety equipment market, Taiwan annual inquiry, gate inhibition's device sales rate of growth is 25%, exceeds tens times more than of other security device rate of growth.

Adopt wired RS485 bus to connect and existing gate control system is most of, the access controller installation need be opened wall, has destroyed the attractive in appearance of body of wall.And before installing, also need great amount of time to carry out wiring installation, waste time and energy, just in case certain data lines wrong, whole network subsequent control device is neither to be used, and debugging quite bothers effort.Such gate control system is installed has sizable engineering difficulty.

The utility model content

For solving the deficiency that above-mentioned technology exists; The utility model provides a kind of wireless entrance guard controller based on technology of Internet of things; As long as the user stands in respective doors outward less than the time about 1S, controller just can detect the needs that open the door through infrared induction, and automatic comparison information; Determine whether to open the door, and corresponding information is stored and uploads.Controller can also write down the signal intensity of corresponding RF ID label simultaneously; The intensity of the radiofrequency signal through label that everyone is held is carried out the multiple spot check and analysis like this; Can locate the position of each label; The indirect scope of activities that can confirm everyone certain period is to reach the function of location.

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

A kind of wireless entrance guard controller based on technology of Internet of things; Comprise a single-chip, be connected with RFID card reader module, gate inhibition's control module, ZigBee radio receiving transmitting module, signal amplification module, infrared induction module, power module and driving circuit on the said single-chip respectively.

Further, be connected with clock module on the said single-chip.

Further, be connected with reservoir module on the said single-chip.

Further, be connected with manual control module on the said single-chip.

The principle of work of the utility model is:

This controller mainly is made up of RFID card reader module, gate inhibition's control module, ZigBee radio receiving transmitting module, signal amplification module, infrared induction module etc.

The RFID card reader adopts contactless Card Reader, continuous emitting radio frequency signal, and the RFID label adopts active label, receives radiofrequency signal and is then waken up and return corresponding information and give card reader.

Gate inhibition's control module adopts the 12V direct supply relay control gate magnetic of locking a door.

The ZigBee radio receiving transmitting module adopts the ZStack2007 wireless transmission protocol of TI company, realizes the point-to-point transmission and the MANET function of increasing income.The mutual networking of each acquisition node also can be used as routing node forwarding corresponding information, is transferred on the final coordinator node.All bottom layer node of coordinator node control, and implement final information and upper strata mutual.

The course of work is promptly by the label information in the RFID card reader induction respective range; As user during in the time of standing firm in front of the door about 1S; Controller is confirmed user's needs that open the door through infrared induction; Whether the automatic differentiation of RFID label information according to receiving opens the door, and the information of uploading is on coordinator node.

The beneficial effect of the utility model is:
