Detailed Description
The technical solutions of the exemplary embodiments provided in the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The various embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1 shows a method for matching a fingerprint module according to an embodiment of the present invention. The compatible method of the fingerprint module can comprise steps S11-S14.
S11: the drive information of various types of fingerprint modules is input in advance.
This embodiment is equivalent to adding a fingerprint-driven compatibility function to the terminal. Taking a smart phone as an example, a piece of software is programmed in advance, and the software can be actually represented as a script or a program, and then is installed in an operating system of the smart phone.
After the function is started, the terminal can provide a User Interface (UI), and a User can enter driving information of multiple types of fingerprint modules through the UI, for example, at least one of driving codes, function interfaces and driving algorithms of different types of fingerprint modules. For example, the terminal may call an array FP _ driver _ t _ list [ FP _ DRV _ MAX _ COUNT ] to establish the list.
In addition, the maximum number of the fingerprint modules which are pre-recorded can be limited through software setting when the software is programmed, so that the smooth running of subsequent software is ensured.
S12: and trying to establish communication connection with various types of fingerprint modules in the terminal starting-up stage.
In the boot-up phase, software calls a set FP _ driver _ t _ list [ FP _ DRV _ MAX _ COUNT ] to obtain the type information of the fingerprint modules included in the list, then calls a driver initialization entry function FP _ local _ init () of each type of fingerprint module, and then the driver initialization entry function FP _ local _ init () sequentially attempts to establish communication connection with all types of fingerprint modules in the list by using a Serial Peripheral Interface (SPI).
The embodiment may add a flag bit to each type of fingerprint module according to the result of the attempt to establish the connection, and specifically, for a fingerprint module that successfully establishes the communication connection, the software may call the fp _ load _ status function to add a first flag bit thereto, for example, 1, when fp _ load _ status is equal to 1. For a fingerprint module that has not successfully established a communication connection, the software may call the fp _ load _ status function to add a second flag bit, for example, 0, to the fp _ load _ status function, where fp _ load _ status is equal to 0.
Accordingly, the software can identify the fingerprint module which successfully establishes the communication connection currently through the identification flag bit. For example, software calls fp _ probe functions to sequentially judge whether the value of each fp _ load _ status function is 1, and if yes, the software judges that the communication connection is successfully established with the fingerprint module of the type; if not, the fingerprint module group of the type is judged to be unsuccessfully established communication connection with the fingerprint module group.
For the fingerprint module that has not successfully established communication connection, that is, the fingerprint module that has the second flag bit, this embodiment may delete its corresponding driving information from the driving information list that is recorded in advance, so as to reduce redundant data in the software.
In addition, in order to ensure smooth operation of the subsequent software-driven fingerprint modules, a preset threshold value can be preset in the embodiment when the software is programmed, and the preset threshold value can be the maximum number of fingerprint modules which are input in advance, and can also be the maximum number of fingerprint modules which are freely set by a user according to the smooth software operation requirement and successfully establish communication connection. While determining whether the communication connection is successfully established with the fingerprint module, the present embodiment further determines whether the number of fingerprint modules successfully establishing the communication connection is less than the preset threshold, and executes step S13 when the number of fingerprint modules successfully establishing the communication connection is less than or equal to the preset threshold. When the number of the fingerprint modules that successfully establish the communication connection is greater than the preset threshold, the embodiment may continue to execute step S12, until the number of the fingerprint modules that successfully establish the communication connection is less than or equal to the preset threshold, execute step S13, or select the fingerprint module with the type of the preset threshold that has the shortest time according to the time of establishing the communication connection with the fingerprint modules and execute step S13, or select the fingerprint module with the type of the preset threshold according to other setting conditions and execute step S13.
S13: and acquiring the identification information of the fingerprint module successfully establishing the communication connection.
Software can acquire identification information of the fingerprint modules from various types through SPI interface commands or other communication modes, and corresponding nodes are created. The Identification information includes, but is not limited to, manufacturer information and model ID (Identification) information of the fingerprint module.
S14: acquiring the driving information of the fingerprint module corresponding to the identification information, and driving the fingerprint module to perform fingerprint identification according to the acquired driving information.
The software can call an intermediate layer of the terminal system, such as a hardware (hardware abstraction) layer, read corresponding identification information from each node so as to judge the type of the fingerprint module, and then inquire the driving information of the fingerprint module from a driving information list according to the identification information. Further, utilize drive information drive fingerprint module to carry out fingerprint identification. Specifically, the software can initialize the function interface of the fingerprint module to realize the functions of fingerprint registration, image acquisition, authentication and the like, and select a corresponding driving algorithm to judge whether the input fingerprint is matched with the acquired fingerprint.
By the above, in the embodiment, for the fingerprint module successfully establishing the communication connection, only one corresponding fingerprint module needs to be selected from the driving information of the fingerprint modules of various types which are input in advance according to the identification information of the fingerprint module, and the driving compatibility of the fingerprint modules of different types can be realized through one software by inputting the driving information of various types into one software in advance.
Please refer to fig. 2, which is a specific application example of the fingerprint module compatibility method of the present invention. The whole process of the foregoing embodiment is implemented by this application example, which is not described herein again.
Fig. 3 is a schematic structural diagram of a terminal with a fingerprint module according to an embodiment of the present invention. As shown in fig. 3, the terminal 30 includes a processor 31, a memory 32, and a communicator 33, and the memory 32 and the communicator 33 may be connected to the processor 31 through a communication bus 34.
The memory 32 is used for recording the driving information of various types of fingerprint modules in advance. The communicator 33 is used for attempting to establish a communication connection with various types of fingerprint modules during the power-on phase of the terminal 30. The processor 31 is configured to obtain identification information of the fingerprint module that successfully establishes a communication connection with the communicator 33. Processor 31 is further used for acquireing the drive information of the fingerprint module that corresponds with identification information to drive the fingerprint module according to the drive information who acquires and carry out fingerprint identification.
In this embodiment, the processor 31 may add a flag bit to each type of fingerprint module according to the result of the attempt to establish the connection, and specifically, for a fingerprint module that successfully establishes the communication connection, the processor 31 may call the fp _ load _ status function to add a first flag bit thereto, for example, 1, when fp _ load _ status is equal to 1. For a fingerprint module that has not successfully established a communication connection, the processor 31 may call the fp _ load _ status function to add a second flag bit, for example, 0, to the fp _ load _ status function, where fp _ load _ status is equal to 0. Accordingly, the processor 31 can identify the fingerprint module that is currently and successfully establishing the communication connection by identifying the flag bit.
For the fingerprint module that has not successfully established a communication connection, that is, the fingerprint module that has the second flag bit, the processor 31 may delete its corresponding driving information from the driving information list that is previously recorded, so as to reduce redundant data in the software running.
In addition, in order to ensure smooth operation of the subsequent software-driven fingerprint modules, the processor 31 may preset a preset threshold value during software programming, where the preset threshold value may be the maximum number of fingerprint modules that are entered in advance, or the maximum number of fingerprint modules that are successfully established for communication connection according to the smooth software operation requirement of the user. When determining whether the communication connection is successfully established with the fingerprint module, the processor 31 further determines whether the number of the fingerprint modules successfully establishing the communication connection is smaller than the preset threshold, and acquires the identification information when the number of the fingerprint modules successfully establishing the communication connection is smaller than or equal to the preset threshold.
The above structural elements of the terminal 30 of the present embodiment correspondingly implement the compatible method of the fingerprint module of the above embodiment, and have the same technical effects.
The terminal 30 includes, but is not limited to, a mobile terminal such as a smart phone, a PDA (Personal Digital Assistant) or a tablet computer, and a wearable device with a fingerprint module, which is worn on a limb or embedded in clothes, jewelry or accessories.
