FIG. 2 is a schematic block diagram of the locking mechanism;

the objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention;

referring to fig. 1, in a preferred embodiment, the positioning anti-detachment electronic tag includes a locking mechanism, a micro planetary motor for controlling the locking mechanism to operate, a driving circuit for driving the micro planetary motor, and a positioning circuit and a wireless communication circuit electrically connected to the driving circuit, wherein the positioning circuit is capable of detecting a coordinate position of the tag and uploading the coordinate position through the wireless communication circuit; the wireless communication circuit can receive a wireless control signal and control the locking mechanism to act through the driving circuit; the anti-dismounting and anti-idle lock control circuit can judge whether the lock is dismounted or the lock is idle through the current of the metal locking rope and send warning information through the wireless communication circuit;

referring to fig. 2, the locking mechanism includes a moving member, a rotating ejector rod, an ejector pin, and a movable ejector rod, wherein the moving member has an annular groove with a trapezoidal cross section, the rotating ejector rod is an arc-shaped metal locking plate and is driven by a micro planetary motor to rotate, the rotating ejector rod can push the moving member to contact with the ejector pin, and the movable ejector rod can switch between two states, namely locking or unlocking the moving member along the pulling direction at different positions. More specifically, the positioning anti-dismantling electronic tag comprises a lock shell, a metal locking rope with the tail end fixed in the lock shell, a switch circuit for connecting the fixed end and the movable end of the metal locking rope, a micro planetary motor driving circuit packaged in the lock shell, a lock hole formed in the side wall of the lock shell and used for inserting the movable end of the metal locking rope, and a linkage locking plate arranged on a power shaft of the micro planetary motor and positioned beside the lock hole; the driving circuit of the motor is controlled by two signals, one is local locking, the movable end is directly and correctly inserted into the lock hole to reach the correct locking position, the driving circuit gives a locking signal, and the linkage locking piece enters the clamping groove of the movable part under the driving of the planetary motor to fix the movable end of the locking rope. And the other one is to receive wireless signals, the signals can be given by a handheld terminal or other types of equipment, the electronic tag is internally provided with a communication system, unlocking and locking signals can be correctly identified, and when the signals for locking or unlocking are received, the embedded system sends instructions to the driving circuit to realize the locking and unlocking actions of the micro planetary motor. The lock case also encloses a connector with a spring plate connected to the drive control circuit, and performs a locking action unconditionally when the connected spring plate is compressed to a maximum stroke. After the external force is removed, the elastic spring is ejected, but the movable terminal can still be electrically connected with the anti-tamper lock control circuit. When the anti-theft lock is in work, when the metal rope is damaged by external force, the metal locking rope is disconnected as a lead, the anti-theft lock control circuit detects the disconnected state, alarm information can be sent to a management center in a wireless mode, and meanwhile, a local buzzer gives a warning sound. When the locking mechanism acts, if the movable terminal is not correctly positioned at the locking position, even if the locking action is executed, because the metal locking rope does not form a closed loop with the anti-dismounting and anti-idle locking control circuit, the anti-dismounting and anti-idle locking control circuit can detect the disconnection state, immediately sends out alarm information to a management center in a wireless mode, and simultaneously sends out alarm sound at a local buzzer. The moving part is provided with an annular groove with a trapezoidal section, and a rotating ejector rod of the planetary motor is an arc-shaped metal locking plate. The thickness of the rotary ejector rod is smaller than the opening size of the groove. The direction of the movement of the locking plate and the direction of the movable part form a certain included angle. The included angle is used for enabling the arc-shaped metal locking plate to bring a downward force to enable the movable piece to be contacted with the thimble in the locking process. When the head of the movable ejector rod reaches the position B, the movable part is locked along the pulling direction and cannot be pulled out, and when the head of the movable ejector rod reaches the position A, the movable part is unlocked. Can be pulled out along the pulling-out direction. When the moving part correctly enters the locking position, the whole system forms a current signal I of the anti-dismounting and anti-lost lock, once the metal locking rope is cut off or the movable end of the metal locking rope does not reach the locking position, the I cannot be formed, and the system generates an alarm signal;

in addition, in a further preferred embodiment, the electronic tag shell is provided with a function key, so that unlocking can be requested, and the electronic tag shell can also be used as an SOS key. The electronic tag positioning circuit can keep communication with a base station, dynamically detects the position level and the height value of the electronic tag, and uploads the position level and the height value through the wireless communication circuit.
