It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 2 is a schematic flowchart of Embodiment 1 of a data processing method provided by an embodiment of this application. The data processing method provided by the embodiment of the present application is applied to the smart lock system described in FIG. 1. 1, the smart lock system includes a processing device and a fingerprint acquisition device, and the processing device includes a fingerprint processing module.

Exemplarily, as shown in FIG. 2, the method may include the following steps:

Step 21: The processing device receives a user operation request, and the user operation request is used to indicate that the working state of the fingerprint processing module is a target working state corresponding to the user operation request.

Exemplarily, in this embodiment, the fingerprint processing module of the smart lock system may be integrated in the processor of the processing device based on the embedded real-time operating system, that is, an independent fingerprint processing thread task is established in the processor, and the The fingerprint processing module processes operations related to fingerprint processing thread tasks, maintains the working status of the fingerprint processing module, and saves the processing results of the fingerprint processing thread tasks and the fingerprint status set.

Optionally, by adding a fingerprint processing module to the processing device to provide corresponding interface services for other applications, the processing device can not only receive the processing results returned by the fingerprint acquisition device, but also receive the user's delivery through the application on the terminal device To control the fingerprint processing module to work in a target working state corresponding to the user operation request.

Optionally, the processing device can receive the user operation request in at least the following two ways:

As an example, the processing device receives the user operation request sent by the fingerprint acquisition device, and the user operation request is generated by the fingerprint acquisition device based on the acquired operation of pressing the control button by the user.

In this embodiment, when the user performs an operation such as pressing on the fingerprint acquisition device, the fingerprint acquisition device generates a user operation request and sends it to the processing device.

For example, if the user presses the registration button, delete button, query button or fingerprint priority setting button on the fingerprint acquisition device, it will trigger the fingerprint acquisition device to generate a fingerprint registration request, fingerprint deletion request, fingerprint query request or fingerprint priority setting Request etc.

It is worth noting that the operation of the fingerprint acquisition device to generate the above user operation request does not require the participation of the controller of the fingerprint acquisition device. When the user presses the control button and other operations, it will directly generate the user operation request and send it to the processing device. .

As another example, the processing apparatus receives the user operation request sent by the terminal device, where the user operation request is generated by the terminal device based on the acquired user input operation.

In this embodiment, if the user clicks the registration button, query button, delete button, or fingerprint priority setting button through the user interaction interface of the terminal device, the terminal device will be triggered to generate the corresponding fingerprint registration request, fingerprint deletion request, fingerprint query Request or fingerprint priority setting request, etc.

Exemplarily, in this embodiment, the working state of the fingerprint processing module may include: recognition state, registration state, and idle state.

Among them, the recognition state is the default working state of the fingerprint processing module, and the recognition state can be switched between the registered state and the idle state.

Correspondingly, the fingerprint processing module performs fingerprint recognition operations with the fingerprint acquisition device in the recognition state, performs fingerprint registration operations with the fingerprint acquisition device in the registration state, and performs at least one of the following operations with the fingerprint acquisition device in the idle state: Fingerprint deletion, fingerprint query, fingerprint priority setting.

Therefore, in this embodiment, the aforementioned user operation request may be at least one of a fingerprint identification request, a fingerprint registration request, a fingerprint deletion request, a fingerprint query request, and a fingerprint priority setting request. Correspondingly, the fingerprint recognition request is used to indicate that the working status of the fingerprint processing module is the recognition state, and the fingerprint registration request is used to indicate that the working state of the fingerprint processing module is the registered state, fingerprint deletion request, fingerprint query request, fingerprint priority setting request, etc. Indicates that the working state of the fingerprint processing module is idle.

It is worth noting that when the fingerprint processing module is in the default working state, it will periodically send identification instructions to the fingerprint acquisition device, so that the fingerprint acquisition device can directly perform the identification operation when receiving a user identification request without reporting the fingerprint to the processing device. Identify the request to improve the efficiency of identification.

Optionally, in this embodiment, the idle state is a working state of the fingerprint processing module in addition to the identification state and the registration state. In the idle state, the fingerprint processing module can execute fingerprint deletion instructions, fingerprint query instructions, and fingerprints Priority setting instructions and other user operation instructions that do not require interaction with the user during execution. The idle state does not simply mean that the fingerprint processing module is not working, but that the fingerprint processing module can complete some operations that can be processed without interacting with the user in this state. These operations are non-blocking and the processing device can control fingerprint acquisition The device directly completes the corresponding operation.

It is worth noting that, in this embodiment of the present application, the user operation requests that can be received or acquired by the processing device are not limited to the foregoing ones, and can be determined according to actual conditions.

Step 22: Generate a user operation instruction according to the above user operation request.

The user operation instruction is used to instruct the fingerprint processing module and the fingerprint acquisition device to perform the operation corresponding to the user operation instruction.

Optionally, in this embodiment, after receiving the above-mentioned user operation request, the processing device triggers the fingerprint processing module to generate a corresponding user operation instruction. For example, generate fingerprint recognition instructions based on fingerprint recognition requests, generate fingerprint registration instructions based on fingerprint registration requests, generate fingerprint deletion instructions based on fingerprint deletion requests, generate fingerprint query instructions based on fingerprint query requests, and generate fingerprint priority setting instructions based on fingerprint priority setting requests Wait.

Exemplarily, the user operation instruction can be used to instruct the fingerprint processing module and the fingerprint acquisition device to perform corresponding operations to implement various services such as fingerprint identification, fingerprint registration, fingerprint deletion, fingerprint query, etc., and perform fingerprint processing results and fingerprints Update of the state set.

Step 23: The processing device controls the fingerprint processing module to interact with the fingerprint acquisition device in the target working state, completes the operation corresponding to the user operation instruction, and obtains the processing result.

Optionally, in this embodiment, when the working state of the fingerprint processing module is the target working state, the processing device may control the fingerprint processing module to interact with the fingerprint acquiring device to perform the operation corresponding to the above-mentioned user operation instruction, Correspondingly complete the corresponding operation in the target working state, and finally get the processing result.

Exemplarily, the processing result may include operation completion information, an updated fingerprint status set, and the like.

For example, if the user operation instruction is a fingerprint registration instruction, the processing result may be the completion information of the fingerprint registration operation and the registered fingerprint information after the fingerprint processing module and the fingerprint acquisition device interact. Optionally, assuming that each registration operation includes N times (where N is a positive integer) fingerprint collection steps, the processing result includes N times collection results (successful collection or collection failure, if it is a collection failure, it includes collection failure The reason) and the fingerprint information collected N times.

Optionally, if the user operation instruction is a fingerprint identification instruction, the processing result includes identification completion information of successful identification or identification failure, and identification failure reason of identification failure.

Optionally, if the user operation instruction is a fingerprint deletion instruction, the processing result includes deletion completion information for deletion success or deletion failure, and deletion failure reason when the deletion fails.

For other fingerprint query instructions or fingerprint priority setting instructions in the idle state, the processing result is similar to the processing result of the fingerprint deletion instruction, and will not be repeated here.

It is worth noting that, for the specific implementation of step 23, refer to the embodiment shown in FIG. 5 below, which will not be repeated here.

In this embodiment, the processing device serves as the control core of the smart lock system and the intermediate layer between the terminal device and the fingerprint acquisition device. It can not only interact with the fingerprint acquisition device at the bottom level, but also provide external services for the upper terminal device application. Interface services, data query, status query and notification services improve the compatibility of processing devices and provide implementation conditions for the development of expandable functions of the smart lock system.

In the data processing method provided by the embodiment of the application, the processing device receives a user operation request, and the user operation request is used to indicate that the working state of the fingerprint processing module is the target working state, and the user operation instruction is generated according to the user operation request to control the fingerprint processing module to operate Interact with the fingerprint acquisition device in the target working state to complete the operation corresponding to the user operation instruction. In this technical solution, the processing device can control the fingerprint processing module to interact with the fingerprint acquisition device, realize the unified management of instruction operations, improve the stability of the smart lock system, and enhance the user experience.

Exemplarily, on the basis of the foregoing embodiment, FIG. 3 is a schematic flowchart of Embodiment 2 of a data processing method provided in an embodiment of this application. As shown in Fig. 3, before the above step 22, the method may further include the following steps:

Step 31: If the current working state of the fingerprint processing module is not the target working state, the processing device controls the working state of the fingerprint processing module to switch to the target working state.

Optionally, in this embodiment, when the processing device receives a user operation request, it first determines whether the current working state of the fingerprint processing module is the target working state indicated by the user operation request. If the current working state of the fingerprint processing module is the target working state, a user operation instruction is generated, and the fingerprint processing module and the fingerprint acquisition device are controlled to interact to perform the operation corresponding to the user operation instruction. If the current working state of the fingerprint processing module is not the target working state, it is necessary to first control the working state of the fingerprint processing module to switch to the target working state, and then perform the corresponding operation.

Exemplarily, assuming that the user operation request is a fingerprint registration request, and the current working state of the fingerprint processing module is the recognition state, first switch the working state of the fingerprint processing module to the registered state, and then perform the corresponding operation.

In the same way, when the user operation request is a fingerprint deletion request, a fingerprint query request, or a fingerprint priority setting request, the switching of the working state of the fingerprint processing module is similar to the operation of the above fingerprint registration instruction, and will not be repeated here.

Optionally, in this embodiment, referring to FIG. 3, after step 23, the method may further include the following steps:

Step 32: The processing device saves the processing result, and controls the working state of the fingerprint processing module to switch to the default working state.

Optionally, in this embodiment, the processing device may save the processing result obtained in the foregoing steps. Specifically, in the smart lock system of this embodiment, the processing device may include a storage unit, and the storage unit may be integrated in the fingerprint processing module. Therefore, the processing device can save the obtained processing result in the storage unit, so that the processing device can increase the response speed when receiving other operation requests, thereby improving the stability of the smart lock system.

The main purpose of the smart lock system is fingerprint identification and unlocking. In this embodiment, the identification state of the fingerprint processing module can be set as the default working state.

Exemplarily, if the working state of the fingerprint processing module is not the default working state, after the processing device completes the operation corresponding to the target working state and the processing result is obtained, the working state of the fingerprint processing module can be controlled to automatically switch to the default working state, that is, identification Status to improve the intelligence and user experience of the smart lock system.

A specific example is given below for illustration:

Normally, the default working state of the fingerprint processing module in the normal working process is the recognition state, that is, the fingerprint processing module can be controlled when it has not received other requests than the fingerprint recognition request sent by the upper application or the fingerprint acquisition device In the recognition state, the fingerprint processing module will periodically send recognition instructions to the fingerprint acquisition device so that the fingerprint acquisition device is in a state of waiting to accept the user's pressing operation, so that the fingerprint acquisition device can accept the user's pressing operation at any time and send it to the fingerprint processing module Send a fingerprint identification request so that the fingerprint processing module and the fingerprint acquisition device cooperate to complete the fingerprint identification operation.

Optionally, when the user triggers the terminal device to send a fingerprint registration request to the processing device through the application on the terminal device or the registration button on the fingerprint acquisition device, the processing device first controls the fingerprint processing module to cancel the current recognition state and switch to IDLE )status.

The fingerprint processing module generates a fingerprint registration instruction according to the fingerprint registration request, and sends the fingerprint registration instruction to the fingerprint acquisition device, so that the fingerprint acquisition device switches to the registration state according to the fingerprint registration instruction. At this time, the user can press the fingerprint sensor to perform Fingerprint registration operation. Optionally, each registration operation can collect N valid fingerprint information. Among them, N is a positive integer; optionally, in order to improve the accuracy of subsequent recognition, N can be equal to 8.

Optionally, during the registration operation, the fingerprint acquisition device will send the collection result and fingerprint information to the processing device every time it collects a valid fingerprint information. Accordingly, the processing device can save the collection result and fingerprint received each time Information, for example, save it to a storage unit. It is worth noting that in some special scenarios, the processing device can also feed back the acquired collection results and fingerprint information to the smart lock application on the terminal device in time.

In this embodiment, when the fingerprint processing module and the fingerprint acquisition device successfully complete each registration operation (the N fingerprint information of a finger is successfully collected), or when the user cancels the registration operation, the fingerprint processing module of the processing device will Automatically switch to the default recognition state.

It is worth noting that when the processing device obtains the fingerprint deletion request, fingerprint query request or fingerprint priority setting request, the processing device can control the fingerprint processing module to switch its working state from the recognition state to the idle state, and then the fingerprint processing module is in In idle state, it generates corresponding fingerprint deletion instruction, fingerprint inquiry instruction or fingerprint priority setting instruction according to fingerprint deletion request, fingerprint inquiry request or fingerprint priority setting request, and controls the fingerprint processing module and fingerprint acquisition device to perform corresponding processing, And switch back to the recognition state after processing.

It can be understood that, as the control core, the processing device can perform data communication with the fingerprint acquisition device, and the fingerprint processing module maintains the processing result of the user operation instruction during the operation of the processing device. At the same time, when the processing device is powered on or the processing device completes corresponding operations in other working states, the working state of the fingerprint processing module can be automatically switched to the default recognition state.

For example, the fingerprint processing module of the processing device can maintain the fingerprint operation and working status inside the processing device. By default, the fingerprint processing module works in the recognition state; when the fingerprint acquisition device determines that the fingerprint sensor is pressed by a finger, it performs fingerprint recognition and sends the recognition result to the processing device for storage. When other requests are received, the current recognition state will be cancelled, the idle state or the registered state will be switched to, and the corresponding command will be generated and sent to the fingerprint acquisition device for corresponding operations.

In the data processing method provided by the embodiments of the application, when the current working state of the fingerprint processing module is not the target working state indicated by the user operation instruction, the processing device can control the working state of the fingerprint processing module to switch to the target working state, and save the above processing As a result, and control the working state of the fingerprint processing module to switch to the default working state. This technical solution improves the intelligence of the processing device, improves the recognition efficiency, reduces the response time of the smart lock system, and improves the user experience.

In the following, the data processing method when the user operation request is a fingerprint identification request and a fingerprint registration request will be explained in conjunction with the above embodiment.

In a possible design of this embodiment, the aforementioned user operation request is a fingerprint identification request, and the target working state corresponding to the fingerprint identification request is the identification state.

Correspondingly, the above step 21 can be implemented through the following steps:

The processing device generates a fingerprint identification instruction according to the fingerprint identification request.

The above step 23 can be achieved through the following steps:

In this embodiment, when the fingerprint processing module is working in the recognition state, the processing device can send the fingerprint recognition instruction to the fingerprint acquisition device so that the fingerprint acquisition device performs fingerprint recognition, and receives the recognition result sent by the fingerprint acquisition device to complete the fingerprint Identification process.

In practical applications, the fingerprint processing module can periodically send identification instructions to the fingerprint acquisition device in the recognition state to make the fingerprint acquisition device work in a state of waiting for the user to recognize (for example, the user presses the fingerprint sensor), and the fingerprint acquisition device acquires After the fingerprint recognition request is received and the fingerprint recognition operation is performed, the obtained recognition result is sent to the processing device, or the fingerprint acquisition device does not detect the user's fingerprint pressing operation after a timeout, and returns the result that the finger is not pressed to the fingerprint processing module, then the processing device Then automatically send a new identification instruction to the fingerprint acquisition device so that the fingerprint acquisition device continues to wait for the user's identification request.

In another possible design of this embodiment, the aforementioned user operation request is a fingerprint registration request, and the target working state corresponding to the fingerprint registration request is the registration state.

The processing device generates a fingerprint registration instruction according to the fingerprint registration request.

The above step 23 can be achieved through the following steps:

The processing device controls the fingerprint processing module to perform at least N interactions with the fingerprint acquisition device based on the fingerprint registration instruction in the registration state, and acquire a registration result including N valid fingerprint information.

Among them, N is a positive integer.

In this embodiment, when the fingerprint processing module is working in the registered state, the processing device controls the fingerprint processing module to continue to work in the registered state until the fingerprint acquisition device sends the collected N valid fingerprint information to the processing device, and the processing device determines When the N valid fingerprint information meets the preset requirements, it is determined that the registration process ends.

Optionally, during the interaction between the fingerprint processing device and the fingerprint acquisition device, the processing device first sends the fingerprint registration instruction to the fingerprint acquisition device, and the fingerprint acquisition device collects one piece of fingerprint information, whether the collected fingerprint is valid and invalid The reason for the time is sent to the fingerprint processing module until the fingerprint acquisition device collects N valid fingerprint information.

Exemplarily, on the basis of any of the foregoing embodiments, FIG. 4 is a schematic flowchart of Embodiment 3 of the data processing method provided in an embodiment of this application. As shown in Figure 4, in this embodiment, the method may further include the following steps:

Step 41: The processing device detects whether the fingerprint processing module is faulty.

Optionally, in this embodiment, the processing device adds a fault detection and fault handling mechanism compared to the processor in the prior art. Therefore, the processing device can detect whether the fingerprint processing module is malfunctioning. Specifically, the detection can be performed in two ways, but the following detection methods are not limited.

In a possible design of this embodiment, this step 41 can be implemented in the following manner:

After sending a user operation instruction to the fingerprint acquiring device, the processing device detects whether the processing result fed back by the fingerprint acquiring device is received within a preset time limit; if the processing result fed back by the fingerprint acquiring device is not received within the preset time limit, the processing device It can be determined that the fingerprint processing module is faulty.

Generally, after the processing device sends a user operation instruction to the fingerprint acquisition device, the fingerprint acquisition device will feed back a processing result after performing the corresponding operation. Therefore, according to the statistical duration of the processing device sending user operation instructions and receiving the processing result, a preset time limit can be set in the processing device of this embodiment to determine whether the fingerprint processing module is present by using the relationship between the statistical duration and the preset duration malfunction. It should be noted that the duration of the preset time limit is greater than the aforementioned statistical duration.

Exemplarily, if the processing device does not receive the processing result fed back by the fingerprint acquisition device within the preset time limit after sending the user operation instruction to the fingerprint acquisition device, it may be determined that the fingerprint processing module is faulty, otherwise, the fingerprint processing module may be determined No failure occurred.

Optionally, in this embodiment, the processing result may be correct response information. The correct response information is the result fed back by the fingerprint acquisition device according to the received user operation instruction.

In another possible design of this embodiment, this step 41 can also be implemented in the following manner:

The processing device detects whether a waiting message periodically sent by the fingerprint acquiring device is received; if the waiting message periodically sent by the fingerprint acquiring device is not received, the processing device determines that the fingerprint processing module is faulty.

In this embodiment, while the processing device is waiting to receive a user operation instruction, the fingerprint acquisition device may be configured to periodically send a waiting message to the fingerprint processing module. The embodiment of the present application does not limit the time interval between two cycles, which can be determined according to actual conditions.

Exemplarily, if the processing device does not receive the waiting message periodically sent by the fingerprint acquisition device, that is, the processing device does not detect that the fingerprint processing module periodically receives the waiting message, then it can be determined that the fingerprint processing module is faulty, otherwise , Confirm that the fingerprint processing module is not faulty.

Step 42: If it is determined that the fingerprint processing module is faulty, the processing device performs a reset operation on the fingerprint processing module and the fingerprint acquisition device.

Optionally, in this embodiment, if the processing device determines that the fingerprint processing module is faulty, the processing device may reset the internal state of the fingerprint processing module and reset the fingerprint acquisition device. For example, the processing device may perform operations such as powering off and powering on the fingerprint acquiring device to reset the fingerprint acquiring device.

Step 43: After the fingerprint processing module and the fingerprint acquisition device are re-run, the processing device acquires the fingerprint information set from the fingerprint acquisition device, and stores the fingerprint information set in the storage unit included in the processing device.

Exemplarily, after the processing device resets the fingerprint processing module and the fingerprint acquisition device, the fingerprint processing module, the storage unit, and the temporary data of the fingerprint acquisition device during the previous operation are all lost, and the fingerprint acquisition device’s memory is not Volatile memory, therefore, the fingerprint set information stored in the memory will not be lost. Therefore, after the fingerprint processing module and the fingerprint acquisition device are re-run, the processing device can acquire the registered fingerprint information set from the memory of the fingerprint acquisition device, and store the fingerprint information set in the storage unit.

It is worth noting that after the fingerprint processing module and fingerprint acquisition device are re-run, the working state of the fingerprint processing module is automatically switched to the recognition state, waiting for the user's finger pressing operation or waiting for other requests triggered by the upper layer application of the terminal device.

In this embodiment, the processing device has a timeout detection and failure handling mechanism. If it is determined that the fingerprint processing module is faulty, the fingerprint processing module and the fingerprint acquisition device are reset, which improves the stability of the smart lock system.

In the data processing method provided by the embodiment of the application, the processing device detects whether the fingerprint processing module is faulty, and when it is determined that the fingerprint processing module is faulty, resets the fingerprint processing module and the fingerprint acquisition device, and performs a reset operation on the fingerprint processing module and the fingerprint After the obtaining device re-runs, the fingerprint information set is obtained from the fingerprint obtaining device, and the fingerprint information set is stored in the storage unit of the processing device. In this technical solution, the processing device has a fault detection mechanism. When it is determined that the fingerprint processing module is faulty, the fingerprint processing module and the fingerprint acquisition device can be reset to make the entire fingerprint processing module run again, avoiding jamming, and improving The adaptability and stability of the smart lock system.

Exemplarily, on the basis of any of the foregoing embodiments, FIG. 5 is a schematic flowchart of Embodiment 4 of the data processing method provided in an embodiment of this application. As shown in Figure 5, in this embodiment, the above step 23 can be implemented through the following steps:

Step 51: The processing device processes the user operation instruction based on the UART protocol to obtain the target instruction data packet.

Optionally, in this embodiment, in order to improve the communication security between the processing device and the fingerprint acquisition device, the processing device and the fingerprint acquisition device may communicate based on a preset protocol.

Exemplarily, the preset protocol may be a UART protocol. In this way, after the processing device generates the user operation instruction, it can first obtain the target instruction data packet by encrypting the user operation instruction based on the format of the UART protocol.

Exemplarily, FIG. 6 is a schematic diagram of the composition structure of the target instruction data packet. As shown in FIG. 6, the target instruction data packet generated based on the UART protocol may include: a protocol header located in the first area, an encrypted random number located in the second area, an encrypted user operation instruction located in the third area, and The data packet check value of the fourth area. Therefore, in this embodiment, step 51 can be specifically implemented through the following steps:

Step A1: The processing device sends a random number acquisition request to the fingerprint acquisition device.

Wherein, the random number acquisition request is used to instruct the fingerprint acquisition device to generate the first random number.

Specifically, upper-layer applications such as applications on the terminal device can call the service interface provided by the processing device (for example, a fingerprint registration command interface), and the processing device can first organize a random number acquisition command (that is, a random number acquisition request) , So that the controller in the fingerprint acquisition device at the bottom layer generates the first random number.

It is worth noting that the random number acquisition request is a plain text command, and the processing device does not need to perform encryption processing on it.

Step A2: The fingerprint acquisition device sends the generated first random number to the processing device.

In this embodiment, the fingerprint acquisition device may generate a random number according to the received random number acquisition request, which is called the first random number in this embodiment, and then send the first random number to the processing device, and at the same time, the fingerprint acquisition The device will also temporarily store the first random number to lay a foundation for subsequent analysis of the received target command data packet.

Step A3: The processing device performs a function operation on the received first random number and the second random number generated by itself to obtain a third random number.

Exemplarily, when the processing device requests the first random number from the fingerprint acquisition device, it will also generate a random number, which is called the second random number in this embodiment. The processing device may perform a function operation on the first random number and the second random number to obtain the third random number.

Exemplarily, the function operation may include exclusive OR and shift. The specific form of the function operation can be determined according to the agreement between the processing device and the fingerprint acquisition device, which is not limited in this embodiment.

Step A4: The processing device performs encryption processing on the third random number to obtain an encrypted random number.

Exemplarily, in order to further improve communication security, the processing device may perform encryption processing on the obtained third random number based on a preset encryption algorithm to obtain the encrypted random number, and fill it into the target instruction data packet shown in FIG. 6 In the second area.

Optionally, the foregoing preset encryption algorithm may be a standard AES encryption algorithm, or other encryption algorithms, and this embodiment does not limit the specific form of the preset encryption algorithm.

Step A5: The processing device uses the second random number to perform a cyclic redundancy check CRC check on the user operation command to obtain the command check value.

Optionally, before the processing device encrypts the user operation instruction, it may first use the second random number generated by itself to perform CRC check processing on the user operation instruction to obtain the instruction check value. The specific implementation principle of the CRC check is based on the prior art, and will not be repeated here.

Step A6: The processing device puts the above-mentioned command check value in front of the user operation command, and encrypts the command check value and the user operation command to obtain the encrypted user operation command.

Exemplarily, in order to ensure that the user operation instruction will not be intercepted during the communication process, the processing device may first place the instruction check value obtained in step A5 before the user operation instruction; secondly, the instruction check value and the user operation instruction The entire content of is encrypted based on a preset encryption algorithm to obtain an encrypted user operation instruction; finally, the encrypted user operation instruction is filled into the third area of the target instruction data packet shown in FIG. 6.

Optionally, the preset encryption algorithm may be the preset encryption algorithm in step A4.

Step A7: The processing device performs a CRC check on the protocol header, the encrypted random number, and the encrypted user operation instruction to obtain a data packet check value.

In this embodiment, the processing device performs a polynomial CRC check on the contents in the first three areas of the UART protocol data packet to obtain the data packet check value, which is placed in the target shown in FIG. 6 In the fourth area of the instruction data packet, the completed target instruction data packet is obtained.

In this embodiment, the processing device sends the obtained target instruction data packet to the fingerprint acquisition device, and the fingerprint acquisition device can also execute the corresponding encryption algorithm, which can ensure the correctness and integrity of the transmission of the user operation instruction.

Step 52: The processing device sends the target instruction data packet to the fingerprint acquiring device.

In this embodiment, if the processing device is a target instruction data packet generated based on the UART protocol, the processing device and the fingerprint acquisition device can communicate through the UART protocol bus. Therefore, the processing device will generate the target instruction data packet through the UART protocol bus. Send to the fingerprint acquisition device.

Step 53: The fingerprint acquisition device parses the received target instruction data packet to acquire the above-mentioned user operation instruction.

Exemplarily, in this embodiment, the fingerprint acquisition device may receive the target instruction data packet sent by the processing device through the UART protocol bus, analyze the received target instruction data packet, and parse the target instruction data packet to obtain the user operation instruction .

In this embodiment, the fingerprint acquisition device may perform the decryption process reverse to step 51 based on the encryption process of the user operation instruction in step 51, and sequentially parse out the protocol header, the encrypted random number, and the encrypted user The operation instruction, and then encrypt the encrypted random number and the encrypted user operation instruction, and finally obtain the user operation instruction.

Step 54: The fingerprint acquisition device executes the operation corresponding to the user operation instruction to obtain the operation result.

In this embodiment, if the user operation instruction acquired by the fingerprint acquisition device is a fingerprint registration instruction, the fingerprint acquisition device executes the registration operation. Specifically, during the registration operation, the fingerprint acquisition device will collect each time through the fingerprint sensor. The received fingerprint information, the collection success/failure result and the failure reason are all sent to the processing device, until the preset N valid fingerprint information are collected.

Exemplarily, the fingerprint information obtained by the fingerprint acquisition device during the registration operation process of collecting N valid fingerprint information, the collection success/failure result and the failure reason are collectively referred to as the registration result.

Optionally, if the user operation instruction acquired by the fingerprint acquisition device is a fingerprint identification instruction or a fingerprint deletion instruction or a fingerprint query instruction or a fingerprint priority setting instruction, the instruction acquisition device executes the aforementioned fingerprint identification instruction or fingerprint deletion instruction or fingerprint query instruction Or the fingerprint priority setting instruction obtains the recognition result or the deletion result or the fingerprint priority setting result such as the recognition success/failure and the reason for the failure or the success/failure and the reason for the deletion or the success/failure and the reason for the fingerprint priority setting.

In this embodiment, the registration result, recognition result, deletion result, or fingerprint priority setting result obtained by the fingerprint acquisition device performing the corresponding operation is collectively referred to as the operation result.

Step 55: The fingerprint acquisition device processes the operation result based on the above UART protocol to obtain the above processing result.

In this embodiment, the fingerprint acquisition device also needs to feed back the obtained operation result to the processing device. Since the processing device sends the encrypted target instruction data packet to the fingerprint acquisition device based on the UART protocol, the fingerprint acquisition device also needs to process the obtained operation result based on the same protocol specification (UART protocol) to obtain the processing result to make the fingerprint The acquisition device also complies with the same encryption specification when feeding back the processing result.

Step 56: The processing device receives the processing result returned by the fingerprint acquisition device.

Exemplarily, the fingerprint acquisition device sends the obtained processing result to the processing device, and the processing device can parse it to obtain the operation result obtained by the interaction between the fingerprint acquisition device and the processing device, and store it in the storage unit so that the user can use the terminal device Operate as needed.

In the data processing method provided by the embodiment of the application, the processing device processes the user operation instructions based on the UART protocol to obtain the target instruction data packet, and sends it to the fingerprint acquisition device, and the fingerprint acquisition device analyzes the received target instruction data packet Obtain the above-mentioned user operation instruction, execute the operation corresponding to the user operation instruction to obtain the operation result, and process the operation result based on the UART protocol to obtain the processing result, and the processing device receives the processing result returned by the fingerprint acquisition device. In this technical solution, the processing device and the fingerprint acquisition device adopt a specific communication protocol specification for communication, which improves the security of interaction between the processing device and the fingerprint acquisition device.

Further, in this embodiment, the processing device serves as an intermediate layer between the upper-layer terminal device and the bottom-layer fingerprint acquisition device. It not only has fingerprint information and status management services, but also can be an upper-layer application (for example, BLE/NB- IOT or a series of other upper-layer applications) provide interface services to improve the scalability and compatibility of the processing device. At the same time, the layered design of this embodiment also provides for the different modules of the smart lock system (such as NFC/keyboard, etc.) With the characteristics of high cohesion and low coupling, the user experience is improved.
