The present invention from the point of view of further, can be by being further programmed to two-way touch on this hardware foundation
Send out function, identification function on this basis and further positioning function.
It is described by configuring corresponding program and peripheral circuit to microcontroller (MCU) in order to realize two-way Trigger Function
After microcontroller (MCU) at least can be to respond the trigger signal received from the low frequency reception antenna, by described low
Frequency transmitting antenna sends another trigger signal, and sends a feedback signal by the radio frequency (RF) antenna, wherein receiving tactile
It is that realization is triggered function that signalling, which sends feedback signal, wherein sending another trigger signal, realizes Trigger Function immediately.
In order to realize identification function on this basis, the feedback signal comprises at least tag ID corresponding to affiliated label
Number, if on goods label is passed through into the identification function, you can realize the preliminary inventory of goods " whether there is ".
Electronic tag belonging to designated herein, refer to sending the electronic tag of the feedback signal naturally.
In order to realize identification function on this basis, following configuration must also be done：
The trigger signal sent by the low frequencies antenna comprises at least tag ID number corresponding to affiliated label.It is described
Feedback signal comprises at least the tag ID number included in tag ID number corresponding to affiliated label and received trigger signal.
The feedback signal also includes the antenna ID number that the low frequency reception antenna of trigger signal is received in affiliated label and corresponding
RSSI intensity.The low frequencies antenna is different from the direction of low frequency reception antenna.When the low frequency reception antenna quantity extremely
When few two, the direction of different low frequency reception antennas differs.Certainly, how many individual directions and specifically which present invention be not limited to
A little directions, even it is equidirectional, an optional embodiment of the invention is fallen within, can be sharp respectively in various embodiments of the present invention
With the different directions of different antennae or the difference of position, different coverages is obtained, and then can be according to the difference of RSSI value
Specifically to be calculated.
For example, Fig. 2 is refer to, three low frequency receptions antenna R11, R12 and R13 are configured for label T1, its sector
Area coverage is respectively facing left and right and downside, also configures a low frequencies antenna A1, and three low frequency receptions are configured for label T2
Antenna R21, R22 and R23, its fan-shaped area coverage are respectively facing left and right and downside, also configure a low frequencies antenna
A2, and label T1 is in label T2 upside, it is assumed that label T1 ID is that 1, T2 ID is 2, ID points of label T1 three antennas
It is not 11,12,13, when label T2 sends trigger signal by low frequencies antenna A2, label T1 reception antenna R11 is received
To trigger signal, it is 1 to be now obtained with the tag ID of oneself, and the tag ID for triggering T1 is 2, and receives trigger signal
Reception antenna R11 antenna ID is 11, can determine which two two adjacent labels be by two ID, by antenna ID,
Because the direction of different antennae is different, it can be determined that its relative position.
Certainly, in a particular application, its situation may be more complicated, so also needing to introduce RSSI, the signal that will be received
The parameter of metering is incorporated into, on the one hand receiving the strong and weak of signal by more different reception antennas compares, it can be determined that
Specific position, specific relative distance can also be judged by the absolute figure of signal.
It can be seen that based on above logic, can be specifically real as long as configuring specific application scenarios, calculation and simulation model
The judgement of existing position.
Based on label described above, the present embodiment additionally provides a kind of identification system based on two-way Trigger Function label
System, including background host computer and at least two labels provided by the present invention with two-way Trigger Function, the background host computer are led to
Cross main frame radio frequency (RF) module and realize the transmission of data with the radio frequency (RF) antenna.
Further, on the basis of identification, positioning can also be realized, main frame radio frequency (RF) module comprises at least one
Receiver, the receiver is to receive the signal that the radio frequency (RF) antenna is sent, and the background host computer is at least to foundation
The feedback signal therein judges the position between at least two labels with two-way Trigger Function.
In summary, low frequencies antenna and low frequency reception antenna has been respectively configured for label in the present invention so that different
Label has two-way Trigger Function, so that can pass through low frequencies antenna and low frequency reception antenna between different labels
Between signal transmission realize triggering from each other.
In the case where the mutual triggering of different labels can be realized, for one side, touching for different labels can be realized
Hair identification, so as to realize the identification for the article for being provided with label, for another aspect, connect by different directions antenna in label
The difference of the collection of letters number, also to determine whether that the position relationship between different labels becomes possibility, once between label
Position relationship can interpolate that the determination of the position relationship between that different article also becomes possibility.
