Usually, the character " / " indicates that the objects associated with each other are in an "or" relationship. The terms "first", "second", "third", etc. involved in this application are only used to distinguish similar objects and do not represent a specific ordering of the objects.

[0040] The method embodiment provided in this embodiment can be executed in a smart door lock, a computer or a similar computing device. For example, running on a processor of a smart door lock, Figure 1 : is a hardware structure diagram of the smart door lock of this embodiment. Figure 1As shown, the smart door lock may include a first battery, one or more processors 102 and a memory 104 for storing data; wherein the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above-mentioned smart door lock may also include a transmission device for communication functions and an input and output device 108. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned smart door lock. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0041] Among them, the battery structure of the smart door lock can be considered to be the same. That is, the first battery is an old battery to be replaced, and has the same structure as the second battery. The second battery is a new battery used to replace the first battery. Figure 2 The figure shows a schematic diagram of the structure of the first battery. It includes a first encryption module and a first empty pin; the first encryption module is connected to the processor through the first empty pin, and after the smart door lock is powered on, the first encrypted data is output to the processor in a single bus mode. The first encrypted data is unique, and each battery has its own separate encrypted data. And before leaving the factory, the first encrypted data is stored in the processor or in a memory connected to the processor. Then, each time the smart door lock is powered on, the first encrypted data transmitted by the first encryption module will be decrypted and compared with the first encrypted data stored in the processor. If the two are consistent, the pairing is successful; if the two are inconsistent, the smart door lock cannot be used.

[0042] Among them, the memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the encryption method of the smart door lock battery in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0043] The transmission device 106 is used to receive or send data via a network. The above network includes a wireless network provided by the communication provider of the terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0044] In this embodiment, a method for encrypting a smart door lock battery is provided. Figure 2 Flowchart of the encryption method of the smart door lock battery of this embodiment. Figure 2 As shown, the process includes the following steps:

[0045] Step S210, obtaining corresponding second encrypted data from the barcode of the second battery; the second encrypted data is determined by a second encryption module in the second battery;

[0046] Step S220, when the first battery in the smart door lock is replaced with the second battery, obtaining the third encrypted data corresponding to the second encryption module in the second battery, and performing battery pairing according to the second encrypted data and the third encrypted data;

[0047] Step S230, completing the battery replacement of the smart door lock according to the battery pairing result.

[0048] Specifically, the second battery refers to a regular new battery used to replace the first battery. It has its own unique barcode. The barcode carries the second encrypted data. The second encrypted data is determined by the second encryption module in the second battery. It can be considered that before leaving the factory, the second encryption module set in the second battery outputs the encrypted data in the agreed encryption method.

[0049] When the first battery in the smart door lock is replaced with the second battery, the second encryption module in the second battery is connected to the processor through the second empty pin, and the third encrypted data is output to the processor; so that the processor obtains the third encrypted data corresponding to the second encryption module. The battery pairing is performed based on the second encrypted data and the third encrypted data, and the battery replacement of the smart door lock is completed according to the result of the battery pairing. Among them, there are many ways of pairing, such as: decrypting the second encrypted data and the third encrypted data, and then checking whether the decrypted data are consistent. For example: randomly selecting the corresponding fields in the second encrypted data and the third encrypted data; then checking whether the selected fields are consistent, etc. There is no restriction on the specific pairing method. In other embodiments, in order to ensure the security of data transmission, the processor will pre-set a corresponding decryption method, which corresponds to the encryption method in the second encryption module. That is, it can be considered that both the third encrypted data and the second encrypted data can be decrypted in the processor to obtain the data before encryption. There is no restriction on the encryption method.

[0050] In the related art, the solution adopted is that after the user replaces the battery, the manufacturer needs to decrypt the replaced battery on-site or remotely to complete the replacement. Although this solution can avoid the replacement of batteries with quality problems, it requires the participation of the manufacturer, resulting in a cumbersome battery replacement process and poor battery replacement timeliness. In this embodiment, the corresponding second encrypted data is obtained from the barcode of the second battery; the encrypted data is determined by the second encryption module in the second battery; when the first battery in the smart door lock is replaced with the second battery, the third encrypted data corresponding to the second encryption module in the second battery is obtained, and the battery is paired according to the second encrypted data and the third encrypted data; according to the result of the battery pairing, the battery replacement of the smart door lock is completed, which solves the problem that the manufacturer needs to participate in the related art, resulting in a cumbersome battery replacement process and poor battery replacement timeliness, and prevents the battery from being replaced abnormally, while ensuring the efficiency of replacing normal batteries and improving the user experience.

[0051] The above steps are described in detail below:

[0052] In some of the embodiments, the encryption method of the smart door lock battery further includes the following steps:

[0053] The barcode on the second battery is scanned by the application to obtain the second encrypted data of the second battery; and the second encrypted data is transmitted to the processor of the smart door lock.

[0054] Specifically, the barcode on the second battery can be scanned by the application program, and the second encrypted data of the second battery can be identified from the barcode; and then the second encrypted data can be transmitted to the processor of the smart door lock for subsequent battery matching. The barcode includes but is not limited to a one-dimensional code, a two-dimensional code, and a three-dimensional code; it can be a combination of a one-dimensional code, a two-dimensional code, and a three-dimensional code; for example, the data identified from a one-dimensional code and a two-dimensional code can be combined into the second encrypted data, thereby further improving the confidentiality level and increasing the safety of use.

[0055] The application can be installed on the client, and the user scans the barcode through the application in the client, so that the user can complete the battery replacement anytime and anywhere. The client can be a mobile terminal, a fixed terminal or a portable terminal, such as a mobile phone, a desktop computer, a laptop computer, a notebook computer, a netbook computer, a tablet computer, a personal communication system (PCS) device, a personal navigation device, a personal digital assistant (PDA), an audio / video player, a digital camera / camcorder, an e-book device, a game device or any combination thereof, including accessories and peripherals of these devices or any combination thereof.

[0056] In some of the embodiments, Figure 3 As shown, the encryption method of the smart door lock battery also includes the following steps:

[0057] Step S310, after the first battery in the smart door lock is replaced with the second battery, the second encrypted data generated by the second encryption module is transmitted to the processor in a single bus manner through the second empty pin in the second battery.

[0058] Specifically, the single bus method for transmitting the second encrypted data is as follows: the data is transmitted in the form of high and low level signals according to the agreed encryption method. For example: after the high level output by the second empty pin is pulled down for a preset time (5ms low level), 16-bit data is sent; the high byte (high level) is sent first, and then the low byte (low level), or the low byte (low level) is sent first, and then the high byte (high level); the ratio of high level and low level is used to represent the value of each data bit. For example: the time ratio of high level and low level is 3:1, which represents a value of 1; the time ratio of high level and low level is 1:3, which represents a value of 0. Figure 4 The timing diagram of the second encrypted data shown in the figure shows that the second encrypted data is 96H. In other embodiments, there is no restriction on parameters such as the preset time, the time ratio of the high level and the low level, and the user can set them according to his / her own choice.

[0059] Through this embodiment, the output of the second encrypted data can be completed by utilizing an empty pin in the second battery without increasing additional hardware resources.

[0060] In some embodiments, the battery pairing according to the second encrypted data and the third encrypted data in step S220 includes the following steps:

[0061] Decoding the second encrypted data to obtain second decrypted data;

[0062] Decoding the third encrypted data to obtain third decrypted data;

[0063] The second decrypted data and the third decrypted data are compared, and the battery pairing is completed according to the comparison result.

[0064] Specifically, the second encrypted data and the third encrypted data can be considered to be determined by the second encryption module under different conditions. If no abnormal situation occurs, the second encrypted data and the third encrypted data are consistent. Therefore, the battery pairing is performed based on these two data. Specifically: the second encrypted data and the third encrypted data are decoded respectively according to the pre-agreed encryption method to obtain the corresponding second decrypted data and the third decrypted data. Then compare the second decrypted data and the third decrypted data; if the second decrypted data and the third decrypted data are consistent, the comparison result is a successful pairing. If the second decrypted data and the third decrypted data are inconsistent, the comparison result is a failed pairing.

[0065] Through this embodiment, a direct decoding and comparison method is adopted to simplify the battery pairing process, improve the pairing efficiency, and reduce the occurrence of mispairing.

[0066] In some of the embodiments, the encryption method of the smart door lock battery further includes the following steps:

[0067] After the battery pairing is successful, the second decrypted data is stored in the memory of the processor or the smart door lock.

[0068] Specifically, after the battery pairing is successful, the second decrypted data is stored in the processor or the memory of the smart door lock. If the second decrypted data is stored in the processor, the processor can directly obtain the third decrypted data for battery pairing. If the second decrypted data is stored in the memory, the processor can extract the second decrypted data from the memory and then obtain the third decrypted data for battery pairing.

[0069] Through this embodiment, the second decrypted data is stored in the memory of the processor or the smart door lock in advance, which can avoid the need to re-acquire the second encrypted data every time the battery is paired, and is convenient to use.

[0070] In some embodiments, the step S230 of completing the battery replacement of the smart door lock according to the battery pairing result includes:

[0071] If the battery pairing result is battery pairing failure, the smart door lock function is locked;

[0072] If the battery pairing result is that the battery pairing is successful, the smart door lock function is unlocked and the battery replacement of the smart door lock is completed.

[0073] Specifically, battery pairing can be performed once every time the smart door lock is powered on, and the results of battery pairing include battery pairing failure and battery pairing success. If the battery pairing fails, it is considered that the second battery replaced is not a qualified battery, and there is a safety hazard. All functions of the smart door lock are locked to ensure the user's safety. It is necessary to replace a qualified battery before it can be used normally. If the result of battery pairing is battery pairing success, it is considered that the second battery replaced is a qualified battery. If there is a lock, it is unlocked; otherwise, the battery replacement of the smart door lock is completed.

[0074] Through this embodiment, corresponding processes are executed according to different battery pairing results, thereby improving the safety of using the smart door lock.

[0075] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
