Dynamically starting in the embodiment of device of RFID label tag, described RFID label tag comprises: for storing the RFID chip (diagram) of information, and the inductive coil 10 for powering for described RFID chip; Described device comprises:
Hinder device 20, can switch between the first position and the second position; When described hinder device 20 is in primary importance, described inductive coil 10 can be stoped to power to described RFID chip, when described hinder device 20 is in the second place, described inductive coil 10 cannot be stoped to power to described RFID chip,
Treating apparatus 30, moves to the described second place for controlling described hinder device 20 when being subject to External Force Acting from described primary importance;
Described treating apparatus also resets to described primary importance for controlling described hinder device 20 when external force disappears from the described second place.
The implementation procedure of the device dynamically starting RFID label tag is described:
When the device dynamically starting RFID label tag is in without external force state, inductive coil 10 is in failure state, when inductive coil 10 is in the magnetic field of the antenna generation of Correspondent Node, cannot provide electric energy to RFID chip.
When the device dynamically starting RFID label tag has External Force Acting state, inductive coil 10 is in effective status, when inductive coil 10 is in the magnetic field of the antenna generation of Correspondent Node, can provide electric energy to RFID chip.
By above-mentioned device, RFID label tag can be become under external pressure effect available, namely the information in RFID label tag can be read, and when without unavailable when external pressure, namely the RFID information in RFID label tag not can read, reach the object dynamically starting RFID label tag, meet Internet of Things application to thing and thing, thing and people mutual in, to the demand of Dynamic Recognition scene.
Particularly, according to the difference of application scenarios, the device dynamically starting RFID label tag can adopt the following two kinds mode to realize dynamically starting RFID label tag.
