Referring to fig. 9, an exemplary method for opening/closing a lock according to the present invention includes the steps of:

S100, enabling a handheld device to be close to an electronic lock to be opened/closed, acquiring an EPC code in the electronic lock to be opened/closed, and sending an opening/closing signal to an RFID component 28 corresponding to the EPC code; when the handheld device is close to the electronic lock to be opened/closed, the wireless receiving end 22 in the electronic lock and the wireless transmitting end 32 in the electronic lock to be opened/closed act to generate electric energy to supply power for the driving assembly 24 and the PCB main control assembly 27.

The step S100 specifically includes the steps of:

s101, enabling the handheld device to be close to an electronic lock to be opened/closed, and obtaining an EPC code in the electronic lock to be opened/closed.

The handheld device in step S101 is a handheld device having a pre-stored EPC code library and having an authority to open/close the lock m times. The obtaining process of the handheld device in step S101 is as follows: an initialized handset is obtained. And determining the lockset to be opened/closed, and transmitting the EPC code corresponding to the lockset to be opened/closed to the initialized handheld device through background authorization, so that the EPC code of the lockset to be opened/closed is pre-stored in the handheld device, and the handheld device with a pre-stored EPC code library is obtained. The number of locks to be opened/closed can be one or more, and when the number of locks is more than one, the opening/closing of the locks by one handheld device is realized. Secondly, in order to further guarantee the safety in the process of opening/closing the locking device, the authority of opening/closing the locking device for m times is authorized through the background, wherein m is an integer larger than 0, a counter is arranged in the handheld device, and when the handheld device is opened/closed once, the opening/closing count value of the counter in the handheld device is increased by one. For example, when one unlocking and one locking are performed, the on/off count value of the counter is incremented by two.

S102, judging whether the obtained EPC code is in a pre-stored EPC code library in the handheld device in the step S101 (namely judging whether the electronic lock to be opened/closed is authorized), if so, reading the open/close count value of the counter, and if the count value is smaller than m, sending an open/close signal to the RFID component 28 corresponding to the EPC code.

S200, the RFID component 28 sends the received on/off signal to the PCB main control component 27.

S300, the PCB main control assembly 27 opens/closes the electronic lock according to the opening/closing signal. 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 lock tongue 23 in the electronic lock moves to open/close the electronic lock.

The step S300 specifically includes:

s301, the PCB main control assembly 27 receives the on/off signal.

S302, judging whether the zipper strip 12 is in place, and if the zipper strip 12 is in place, executing step S303.

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

The judging method for judging whether the zipper strip 12 is in place in step S302 is as follows: if the photoelectric signal of the induction zipper strip 12 is obtained, the zipper strip 12 is judged to be installed in place. Specifically, after the zipper strip 12 is installed in place, the bump 122 of the zipper strip 12 is embedded in the U-shaped photoelectric switch 273, the U-shaped photoelectric switch 273 sends the detected signal to the main control chip 272, when the main control chip 272 receives the photoelectric signal, it is determined that the zipper strip 12 is installed in place, and if the photoelectric signal is not received, it is indicated that the zipper strip 12 is not installed in place.

In step S303, the method for determining whether the current position of the lock tongue 23 is the safe position is as follows:

When the signal received by the PCB main control assembly 27 is a closing signal, a first Hall signal is obtained, and the current position of the lock tongue 23 is a safe position; the first hall signal is a hall sensing generated by the first hall sensor 275 and the magnet 231 on the latch 23. Since the first hall sensor 275 is disposed at the initial starting position when the tongue 23 is not extended, when the first hall signal is obtained, it indicates that the tongue 23 is in the state of not extending, and the first hall sensor is in the safe position when no movement occurs.

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

S003, a positioning signal is sent to the RFID component 28 corresponding to the EPC number selected.

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 method, the position of the electronic lock to be opened/closed can be timely obtained in the range, and the electronic lock to be opened/closed can be timely and accurately found in a plurality of banknote transport bags in the range.

It should be noted that the structure of the electronic lock, the lock and the handheld device in the method can refer to the above embodiment 1 and embodiment 2, but is not limited thereto, and the bank note transporting bag in embodiment 2 can be replaced by other carriers, for example, a packaging box, a bag and the like, so that the method of the invention can be expanded in other logistics fields besides money logistics.

According to the electronic lock, the lock for bank note transportation and the opening/closing method of the lock, the power supply to the electronic lock is realized in a wireless power supply mode, the trouble of an external power supply and a power adapter in the prior art is avoided, the operation flow is simplified, and the failure rate caused by the trouble is reduced; and the cost is greatly reduced because the power supply and the power supply adapter are not required to be purchased. In addition, the invention greatly improves the accuracy and the safety of the lockset through background authorization, positioning and multi-layer judgment.

What is disclosed is a method for manufacturing a semiconductor device, which comprises the steps of providing a semiconductor substrate, and forming a semiconductor layer on the semiconductor substrate, wherein the semiconductor substrate is a semiconductor layer, and forming a semiconductor layer on the semiconductor layer.
