Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The system architecture for implementing the locking and unlocking method based on the wireless energy supply technology provided by the embodiment of the application can comprise: a key and a lock.
Wherein, the key can utilize wireless energy supply technique to supply power to the tool to lock in the embodiment of this application. After the lockset obtains electric energy, data interaction can be carried out with the key in a wireless communication mode. The key can be matched with various locks, so that the lock opening and closing control of various locks is realized.
What this application will realize promptly is, the key utilizes wireless energy supply technique to supply power for the tool to lock, after the tool to lock acquireed the electric energy, utilizes wireless communication's mode to carry out data interaction between key and the tool to lock to accomplish the matching of key and tool to lock, and through the switching state of key control tool to lock.
On this basis, the key can send authentication information for the tool to lock at the in-process that utilizes wireless energy supply technique to supply power for the tool to lock to whether confirm that the key is successful for the wireless energy supply of tool to lock through judging whether receiving the affirmation information that the tool to lock returned, if not, then probably mean that the resonant frequency of key and tool to lock is inconsistent, the key can continue to supply energy for the tool to lock through the mode of adjusting resonant frequency this moment, until receiving the affirmation information that the tool to lock returned.
Next, a method for opening and closing a lock based on a wireless power supply technology according to the present application is described in terms of a key, as shown in fig. 1, fig. 1 shows a flowchart of a method for opening and closing a lock based on a wireless power supply technology provided by an embodiment of the present application, and the method may include:
step S100, broadcasting the magnetic field signal and the authentication information.
The magnetic field signal is broadcast at an initial resonant frequency, and the authentication information is used for authenticating the lockset.
Specifically, the key broadcasts a magnetic field signal at an initial resonant frequency. The broadcasted magnetic field signal is broadcasted with initial resonant frequency, and when the resonant frequency of the receiving end of the lock is consistent with the initial frequency, the lock can generate induced electromotive force through the received magnetic field signal, and the electric energy required by the lock is obtained based on the generated induced electromotive force. The broadcasted authentication information can be authenticated with the lock, the lock can receive the authentication information broadcasted by the key after acquiring the electric energy required by the lock through the received magnetic field signal, and the confirmation information can be sent out based on the authentication information. The initial resonant frequency can be obtained through the previous matching condition, and the resonant frequency of most of the locksets is obtained, so that the initial resonant frequency is determined according to the obtained resonant frequency.
And step S101, judging whether confirmation information returned by the lock is received or not.
Specifically, after the lock acquires the electric energy, the corresponding confirmation information can be returned through the received authentication information, so that whether the lock can generate induced electromotive force by using a magnetic field signal broadcasted at the current resonance frequency can be determined by judging whether the confirmation information returned by the lock is received, the required electric energy is acquired, and if not, the step S102 is executed; if yes, go to step S103.
And S102, adjusting the resonance frequency until the confirmation information returned by the lock is received.
The resonant frequency is adjusted so that the magnetic field signal is broadcast at the adjusted resonant frequency.
Specifically, under current resonant frequency, the confirmation information returned by the lock is not received, and then the resonant frequency of the current broadcast magnetic field signal is inconsistent with the resonant frequency of the lock, so that the lock cannot utilize the magnetic field signal of key broadcasting to form induced electromotive force, and required electric energy is obtained, therefore, the resonant frequency needs to be adjusted, the resonant frequency is consistent with the resonant frequency of the lock end, and energy supply to the lock is realized.
And S103, generating locking and unlocking information based on the confirmation information returned by the lock, and sending the locking and unlocking information to the lock according to the instruction of the user.
Specifically, after receiving confirmation information returned by the lock, the unlocking and locking information corresponding to the lock can be generated based on the confirmation information returned by the lock, wherein the unlocking and locking information is included, and the unlocking and locking information can be sent to the lock according to the requirement of a user so that the lock can perform unlocking and locking operation according to the unlocking and locking information.
It can be seen from the foregoing embodiments that, in the method for opening and closing a lock based on a wireless energy supply technology provided in the embodiments of the present application, by broadcasting a magnetic field signal at an initial resonant frequency and broadcasting authentication information for authenticating with a lock, it is determined whether confirmation information returned by the lock is received, and if the confirmation information is not received, the resonant frequency is adjusted so that the magnetic field signal is broadcast at the adjusted resonant frequency until the confirmation information returned by the lock is received; if the confirmation information is received, the lock can utilize the broadcasted magnetic field signal to supply power under the current resonant frequency, so that the lock can receive the authentication information and return the confirmation information, at the moment, the locking and unlocking information can be generated based on the confirmation information returned by the lock, and the locking and unlocking information is sent to the lock according to the instruction of the user, so that the lock can carry out locking and unlocking operation according to the locking and unlocking information.
Further, because the difference of different tool to lock manufacture factory manufacturing process, the resonant frequency of tool to lock energy receiving terminal can be different, if will use the key to supply power for the tool to lock, then need be equipped with corresponding key according to different resonant frequency, and this application is through adjusting resonant frequency for magnetic field signal can be transmitted to the tool to lock with different resonant frequency, thereby accomplish the matching with multiple tool to lock, and then realize the switching lock operation of multiple tool to lock.
In some embodiments of the present application, a process of adjusting the resonant frequency in step S102 is described.
Specifically, the adjusting the resonant frequency may be adjusting the resonant frequency according to a preset adjustment value on the basis of the current resonant frequency; the resonant frequency can also be adjusted by adopting a random number selection mode; according to experience, the resonant frequency can be adjusted according to the most common resonant frequency, and if the confirmation information returned by the lockset is not received, the resonant frequency can be adjusted through the two modes.
When the resonant frequency is adjusted according to a preset adjustment value on the basis of the current resonant frequency, the adjustment value can be determined according to actual requirements. For example, the resonant frequency is adjusted within 110kHz-200kHz, if the resonant frequency is adjusted step by step according to 1kHz, the matching with the resonant frequency of the lockset can be basically realized, but the adjustment time is too long; if the resonant frequency is adjusted gradually according to 10kHz, the adjustment time is relatively shorter, but the resonant frequency cannot be matched with the resonant frequency of the lock after the adjustment is finished, so that the adjustment value can be determined according to actual requirements, and when the resonant frequency is adjusted to 5kHz, the time and the accuracy can be integrated, so that the best effect is achieved.
Furthermore, the resonant frequency of most of the locksets can be obtained through the previous matching condition, and the adjustment value is set by combining the initial resonant frequency. For example, through the previous matching situation, the resonance frequencies of most of the locks are acquired to be 120kHz, 125kHz and 130kHz, and the resonance frequency is adjusted within 110kHz to 120kHz, then the initial frequency at this time can be set to be 110kHz, and the resonance frequency is increased step by 5kHz, which can perform matching more quickly than if the initial frequency is set to be 200kHz, and the resonance frequency is decreased step by 5 kHz.
In some embodiments of the present application, a process of adjusting the resonant frequency in step S102 is described.
Specifically, the resonant frequency can be adjusted by adjusting the resonant square wave signal, and each resonant frequency corresponds to one resonant square wave signal.
Further, when the confirmation information returned by the lock is not received, the adjusted resonance frequency can be determined according to a preset adjustment value on the basis of the current resonance frequency, and the corresponding resonance square wave signal is determined according to the adjusted resonance frequency and is used as the adjusted resonance square wave signal to adjust the resonance frequency.
In some embodiments of the present application, when the lock is unlocked and locked by using the key based on the wireless energy supply technology, because the lock is opened and closed, in order to ensure the security, the communication information between the key and the lock may be encrypted first, and then the encrypted information is transmitted.
In the above embodiment, before broadcasting the magnetic field signal and the authentication information, the authentication information may be encrypted to obtain encrypted authentication information, at this time, the magnetic field signal and the encrypted authentication signal are broadcast, and after receiving the encrypted confirmation information, the lock decrypts the encrypted confirmation information to obtain the decrypted confirmation information, and performs a related operation according to the confirmation information.
In this embodiment, through encrypting authentication information, can ensure to a certain extent and open the shutting in-process, communication safety between key and the tool to lock.
In some embodiments of the present application, when the confirmation information returned by the lock is encrypted, a process of generating lock opening and closing information based on the confirmation information returned by the lock in step S103, and sending the lock opening and closing information to the lock according to an instruction of a user is introduced. As shown in fig. 2, fig. 2 is a flowchart of a method for processing data of an unlocking and locking device based on a wireless power supply technology according to an embodiment of the present application.
And S200, decrypting the confirmation information returned by the lockset to obtain the decrypted confirmation information.
Specifically, after the lock receives a magnetic field signal broadcasted at a resonance frequency consistent with the resonance frequency of the lock, induced electromotive force is generated through the magnetic field signal, required electric energy is obtained, authentication information broadcasted by the key is received, confirmation information is generated based on the authentication information, the confirmation information is encrypted, and then the encrypted confirmation information is returned to the key. And the key decrypts the encrypted confirmation information returned by the received lockset to obtain the decrypted confirmation information.
And step S201, generating locking and unlocking information according to the decrypted confirmation information.
Specifically, in the confirmation information, the information of the lock and the random number can be acquired, the opening and closing lock data corresponding to the lock can be acquired by using the information of the lock, and the information of the lock, the random number and the opening and closing lock data are generated into the opening and closing lock information.
And step S202, encrypting the locking and unlocking information.
Specifically, the key encrypts the locking and unlocking information, and the encryption can be encrypted by adopting an ESAM security module.
And step S203, sending the encrypted lock opening and closing information to the lock according to the instruction of the user.
Specifically, the information of the opening and closing lock comprises unlocking information and locking information, and the unlocking information or the locking information can be selectively sent to the lockset according to the instruction of a user, so that the opening and closing of the lockset is controlled.
In this embodiment, through encrypting the information of confirming and switching lock information, can guarantee to a certain extent to open the shutting in-process, communication safety between key and the tool to lock.
In some embodiments of the present application, the key may also receive lock status information returned by the lock, which may reflect the current open and closed status of the lock.
Specifically, after the lock receives unlocking information sent by the key, unlocking operation is performed based on the unlocking information, and the lock is successfully opened, at the moment, the lock can return lock state information which indicates that the lock is opened, such as prompt information of 'the lock is opened'; after the lockset receives the locking information sent by the key, locking operation is carried out based on the locking information, and the lockset is successfully closed, at the moment, the lockset can return lockset state information which indicates that the lockset is closed, for example, prompt information such as 'the lockset is successfully closed'.
According to the embodiment, the lock state information returned by the lock is received, so that the opening and closing state of the current lock can be obtained more visually through the text information, and the operation of a user is facilitated.
