The PCB main control assembly 27 controls the motor in the driving assembly 24 to rotate according to the opening/closing signal, so that the locking tongue 23 in the electronic lock moves, and the electronic lock is opened/closed.

wherein, the step S300 specifically includes:

S301, the PCB main control component 27 receives the open/close signal.

S302, judging whether the zipper piece 12 is installed in place or not, and if the zipper piece 12 is installed in place, executing the step S303.

And S303, judging whether the current position of the bolt 23 is a safe position, and opening/closing the electronic lock if the current position of the bolt 23 is the safe position.

In step S302, the method for determining whether the zipper 12 is mounted in place includes: and if the photoelectric signal for sensing the zipper plate 12 is acquired, judging that the zipper plate 12 is installed in place. Specifically, after the zipper piece 12 is mounted in place, the bump 122 of the zipper piece 12 is embedded in the U-shaped photoelectric switch 273, the U-shaped photoelectric switch 273 transmits a detected signal to the main control chip 272, when the main control chip 272 receives photoelectric signals, it is determined that the zipper piece 12 is mounted in place, and if the photoelectric signals are not received, it is determined that the zipper piece 12 is not mounted in place.

In step S303, the method for determining whether the current position of the locking bolt 23 is the safe position includes:

When the signal received by the PCB main control assembly 27 is a closing signal, acquiring a first hall signal, and the current position of the lock tongue 23 is a safe position; the first hall signal is a hall sensing between the first hall sensor 275 and the magnet 231 on the locking tongue 23. Since the first hall sensor 275 is located at the initial position when the locking tongue 23 is not extended, when the first hall signal is obtained, it indicates that the locking tongue 23 is in the non-extended state, and when no over-movement occurs, it is in the safe position.

When the signal received by the PCB main control assembly 27 is an on signal, a second hall signal is obtained, and the current position of the latch 23 is a safe position, where the second hall signal is a hall response generated by the second hall sensor 274 and the magnet 231 on the latch 23. Since the second hall sensor 274 is disposed at the position where the locking tongue 23 is fully extended, when the second hall signal is acquired, it indicates that the locking tongue 23 is in the fully extended state at this time, and the position is a safe position if no over-movement occurs.

As one mode, before the step S100 of approaching the hand-held device to the electronic lock to be opened/closed is performed, the opening/closing method of the present invention further includes: and S000, searching the electronic lock to be opened/closed through the handheld device.

Wherein, the step S000 of searching for the electronic lock to be opened/closed through the handheld device specifically comprises the steps of:

And S001, searching a plurality of corresponding EPC numbers in a plurality of electronic locks in the range through the handheld device.

S002, screening EPC numbers corresponding to the electronic locks to be opened/closed from the plurality of EPC numbers.

and S003, sending a positioning signal to the RFID assembly 28 corresponding to the screened EPC number.

S004, the RFID component 28 sends the position information of the electronic lock to be opened/closed to the handheld device.

S005, searching the electronic lock to be opened/closed according to the position information.

By the mode, the position of the electronic lock to be opened/closed can be timely known within a range, and the electronic lock to be opened/closed can be timely and accurately found in a plurality of banknote carrying bags within the range.

It should be noted that, the electronic lock, the lock and the handheld device related to the method can refer to the above embodiments 1 and 2, but are not limited thereto, and it can be expanded that the bank note transporting bag in embodiment 2 can be replaced by other carriers, for example, it can be a packing box, a bag, etc., so that the method of the present invention can be extended to other logistics fields besides currency logistics.

The utility model discloses an electronic lock, the lock for bank note transport and the method for opening/closing the lock, realize the power supply to the electronic lock through the mode of wireless power supply, avoided the trouble of external power supply and power adapter among the prior art, simplified the operation procedure, reduced the fault rate that arouses from this; and because no power supply or power adapter is needed to be purchased, the cost is greatly reduced. Additionally the utility model discloses a backstage is authorized, location and multilayer are judged, have greatly improved the accuracy nature and the security of tool to lock.

The present invention is disclosed in one or more of the preferred embodiments, in which local changes or modifications are made to the invention and are readily suggested to those skilled in the art without departing from the scope of the invention.
