Present invention take advantage of that TOF ranging technologies, are the positioning anti-theft device based on TOF, TOF, flight time (Time of
Fight), TOF ranging technologies are a kind of Bidirectional distance measurement technologies, and one radio signal of 2.4GHz of measurement is in two asynchronous receiving-transmittings
The time spent in being come and gone between machine, such that it is able to extrapolate the actual range between two nodes.Use the method and and sensor
Technology is combined together, it is possible to for being positioned to object.Under sighting distance line-of-sight circumstances, the knot based on TOF range finding estimations
It is really more satisfactory, with apart from linear, so the precision of TOF range findings can be relatively more accurate, just have in many aspects more
It is wide application prospect.
TOF range findings are bidirectional ranging, wherein in the positive range findings of TOF, local node sends a Poll to remote node
Packet, remote node is received after this packet, is sent a response ack msg bag and is returned.Generally use TTOTRepresent local
Node from send Poll packets to receive reply data bag cost time；TTATRepresent that remote node receives poll to sending
The time that reply data bag is spent, wireless data transmits the time T of cost in the airTOFCan be calculated with following equation:
Forward direction range finding depends on the time of local node and remote node measurement, and the measurement of time again relies on both crystalline substances
The accuracy shaken, to reduce the influence of such phenomenon, grace intelligence Pu TOF range findings API provides reverse measuremenet function：By remote node
Packet, local node response are sent, and is automated toed respond to.Averaged by forward direction range finding and reverse range measurement, so that
The influence that crystal oscillator deviation is brought is eliminated, and then reduces the error in range finding.Moreover, if wanting to ensure certainty of measurement, it is necessary to
Ensure that apparatus for transmitting signal and receiving device are synchronous all the time.
In actual test, Prime order initialization tests are sent from local node to remote node, then repeatedly
Above-described test, to packet of the remote node request bag containing range measurement, remote node is received please for last local node
Test result data is sent to local node after asking；Reversely Poll and ACK order transmit-receive positions are opposite in range finding.2.4GHZ believes
Spread speed is the light velocity (299,792,458m/s) number in the air.Because the unit of ToF API return values is psec, it is possible to
Distance is converted to by being multiplied by 0.0003, unit is rice.The distance that TOF measurements are obtained is that wireless signal passes through in two nodes
Distance, if thering is object to block between two nodes, it is possible to cause wireless signal to reflect, cause radio propagation path elongated,
So measurement obtains more long than actual range apart from meeting.Therefore it is also critically important using repeatedly measurement in same position.
The data of positioning are returned and judge whether to decide whether alarm more than default initial value by the present apparatus, and are repeated
This positioning work, data constantly returned and judged.Antitheft purpose can thus be realized.
