Based on the matching information, a main control unit sends a trigger signal so as to awaken the corresponding RFID to perform a fixed-point communication. Through the RFID, the communication system and the method of the invention, the problem that a plurality of RFID groups are awakened is effectively solved; the service life of the cell is effectively increased; the service life of the FRID is prolonged; the risk of interfering the FRID is reduced; and protection mechanism for preventing the FRID from interference is further improved.
Description
Technical field
The present invention relates to the fields such as electric non-stop toll field, warehousing management or parking lot, specifically, relate to a kind of electronic tag and comprise communication system and the communication means of this electronic tag.
Background technology
Electronic tag is owing to used the radio-frequency (RF) identification communication technology, make its application very extensive based on this characteristic, relate to logistics and supplies management, the manufacturing and assembling, luggage processing and road automatic charging, also very large contribution has been made in the application of plastic pallet, Turnround basket in the storage.
Be put into the present situation of use for large batch of electronic tag, existing electronic tag communication mechanism can not improve the battery utilization rate of electronic tag well, has shortened the serviceable life of electronic tag.Use for warehousing management, road parking and logistics management, electronic tag has been brought into play greatly function, for the saveall cost, electronic labelling system of the prior art adopts public awakening mode to communicate, not only the battery management mechanism of electronic tag is perfect not, cause also greatly reduce the serviceable life of battery, and do not meet environmental protection concept.Simultaneously, repeatedly random being waken up also can make the power supply of electronic tag undesired, and its risk that is in the deadlock state is increased.
Relate in the field that electronic tag need to conclude the business for station parking lot management and logistics and supplies management etc., electronic tag is powered on by random waking up repeatedly, be easy to be subject to artificial and unartificial interference, provide to the lawless person and destroyed the chance of electronic tag communication system therefrom to speculate.
At present, electronic tag will be in sleep mode at one's leisure, and working current is less than 20 μ A, and it is extremely low to wake sensitivity up, and roadside unit need to send stronger signal and electronic tag could be waken up.Present roadside unit sends radiofrequency signal, the rf receiver unit of electronic tag receives this radio-frequency wakeup signal and sends trigger pip to wake the internal circuit of electronic tag up to main control unit, when needs wake indivedual electronic tag up, electronic tag on every side also can be waken up by radiofrequency signal simultaneously, the electronic tag that has entered dormant state around namely causing and do not needed to be waken up again is waken up again, the battery capacity of electronic tag around having wasted, shortened the service time of battery, also so that reduce the serviceable life of electronic tag on every side.Simultaneously, repeatedly be waken up without purpose, increased electronic tag and waken the number of times that powers on up, the disturbed risk of its administrative mechanism is increased.For road parking and parking lot management field, station, the general technological means of Parking Meter charge that adopts is carried out fixed service, although with respect to manually-operated certain automatic function is arranged, but also more loaded down with trivial details, be to need the car owner to operate the Parking Meter under normal circumstances self-servicely, buy the card of paying the fees, oneself selects the parking stall, the timing of swiping the card is swiped the card and is paid the fees.Therefore, for the relatively poor car owner of consciousness or forget the car owner of self-help operation Parking Meter, just can't collect the charges, but will take rigid punish the measure to collect the charges, the social contradications of so bringing and the inconvenience of follow-up rigid charge also are apparent.Simultaneously, the Parking Meter adopts artificial charge-by-card, arranges in Fare Collection System that then the height of Parking Meter will be restricted, and general limitation in height can contact the position of swiping the card the car owner, and then the Parking Meter is easy to be destroyed by the people, also can increase much its maintenance cost.Realize that for hand-held set charging function also needs to adopt artificially hand-held set that vehicle is taken pictures to identify car plate or inputs artificially car plate or car item or swipe the card to start clocking capability; And all can there be error in the clock of every hand-held set, and can artificially adjust, so timing uncertainty is true, also has serious human intervention problem.Because the security of electronic tag existing problems, and cost is very high, so electronic tag does not have a large amount of uses in this field.
