For example, different permission accounts are set on the interface end of the television, or a remote control device is added with a restriction means. The restriction means added on the remote control device can be realized through a fingerprint recognition function. That is, whether the remote control device is operated by a permission person is distinguished by using a biological recognition technology, and then the operation of the remote control device by a non-permission person is restricted, so as to avoid the non-permission person from operating the television or program.

[0045] The technical solutions in the embodiments of the present specification will be described clearly and completely in the following with reference to the drawings in the embodiments of the present specification. Obviously, the described embodiments are only part of the embodiments of the present specification, rather than all the embodiments. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present specification.

[0046] In the scenario of remote communication, the remote control system can include a remote control device and an electronic device to be controlled, which can be, for example, a television, a video player, a smart air conditioner, a smart lamp, and the like. The user can control the electronic device by controlling the remote control device. Referring to Figure 1 As shown, taking the electronic device as a television as an example, the user controls the key module of the remote control device to perform program switching, volume adjustment, and the like. The remote control device processes the signal generated by the key module in response to the user's operation through its processing module, generates a control signal, and sends it to the television through the signal transceiver of the remote control device. Then, the television can control its corresponding components according to the received control signal, for example, it can display the corresponding interface on its display screen, or control the volume of the sound signal output by the loudspeaker, and the like.

[0047] In some embodiments, in order to prevent accidental touch or other users from operating the television or program, a biometric identification module can be set on the remote control device to restrict the remote control system. For example, the remote control device can collect the biological information of the user operating the remote control device through the biometric identification module, and send the biological information to the processing module of the remote control device for biometric identification. When it is determined that the identification is successful, it is determined that the user can use the remote control device to control the electronic device. Then, the user can generate corresponding operation signals to the processing module through the key module, and the processing module can generate corresponding control signals and send them to the electronic device through the signal transceiver after receiving the operation signals, thereby completing the control of the electronic device.

[0048] The above method of adding a biometric module on the remote control device and redesigning the software system of the processing module to realize the limitation of the remote control device makes the software system design of the remote control device complex and high in cost. To solve the above problems, the embodiments of the present specification provide a remote control device, which is provided with a controller, a signal transceiver, and a biometric identification part including a data processing component and a biometric sensor. Then, the data processing component can convert the signal output by the biometric sensor to obtain an identification signal representing the biometric identification result, and the component can convert the signal output by the biometric sensor into a user operation signal, so that the controller does not need to process the biometric signal and can directly process the received identification signal, and the function of the controller is simpler. Moreover, the remote control device does not need to be provided with a key module, and the collection and conversion of the user operation signal can be realized through the biometric sensor and the data processing component, which can reduce the design cost of the device.

[0049] The remote control device in the embodiments of the present specification will be described below with reference to the accompanying drawings.

[0050] Reference Figure 2 As shown in the drawings, the embodiments of the present specification provide a remote control device 10, which includes a controller 100, a signal transceiver 200, and a biometric identification part 300, the biometric identification part 300 including a data processing component 310 and a biometric sensor 320; wherein the data processing component 310 includes an induction signal converter 311 and an operation signal converter 312. The induction signal converter 311 and the operation signal converter 312 are connected to the biometric sensor 320, the induction signal converter 311 and the operation signal converter 312 are communicatively connected to the controller 100, and the controller 100 is connected to the signal transceiver 200.

[0051] The biometric sensor 320 is configured to collect a first biometric signal of a to-be-detected object and send the first biometric signal to the induction signal converter 311. The induction signal converter 311 is configured to convert the first biometric signal into an identification signal and send the identification signal to the controller 100. The controller 100 is configured to send a first control signal to the operation signal converter 312 after receiving the identification signal. The operation signal converter 312 is configured to send a second control signal to the biometric sensor 320 after receiving the first control signal, receive a second biometric signal returned by the biometric sensor 320, and convert the second biometric signal into an operation signal and send the operation signal to the controller 100. The controller 100 is further configured to send a third control signal after receiving the operation signal.

[0052] It can be understood that the biological signals collected by the biometric sensor 320 can be converted into identification signals and operation signals by the sensing signal converter 311 and the operation signal converter 312 in the data processing assembly 310, respectively. For example, when the biometric sensor 320 senses that the object to be detected is close, it can collect the corresponding biological information to obtain the first biological signal, and can send the first biological signal to the sensing signal converter 311. The sensing signal converter 311 can convert the first biological signal to obtain the corresponding identification signal, and can send the identification signal to the controller 100. For example, the sensing signal converter 311 and the operation signal converter 312 can be microprocessors. The sensing signal converter 311 can realize feature extraction and template matching identification of the first biological signal through an internal algorithm module to obtain the identification signal. The operation signal converter 312 can realize feature extraction and displacement identification of the second biological signal through an internal algorithm to obtain the operation signal.

[0053] In some embodiments of the present specification, the data processing assembly 310 can include a first pin, and the sensing signal converter 311 and the operation signal converter 312 can connect the biometric sensor 320 through the first pin.

[0054] Further, the first pin and the biometric sensor 320 can be connected through an SPI bus.

[0055] It can be understood that the first pin is used to transmit the signals transmitted between the sensing signal converter 311 and the operation signal converter 312 and the biometric sensor 320, which can include the first biological signal, the second biological signal, the second control signal, and the like.

[0056] In some embodiments of the present specification, the data processing assembly 310 can include two pins, and the sensing signal converter 311 and the operation signal converter 312 can be connected to one pin, respectively. The two pins can be connected to the biometric sensor 320. Further, the signals between different converters and the biometric sensor 320 can be transmitted through different pins, which facilitates the processing and conversion of signals by the converters.

[0057] In some embodiments of the present specification, when the biometric sensor 320 senses the object to be detected, the biometric sensor 320 can send a first signal to the sensing signal converter 311 for waking up the sensing signal converter 311, and then the sensing signal converter 311 can send a second signal to the biometric sensor 320 after being woken up, so that the biometric sensor 320 can collect the biological information of the object to be detected in response to the second signal and output a first biological signal to the sensing signal converter 311. Further, the data processing assembly 310 can further set a second pin and a third pin, the second pin and the third pin being connected to the biometric sensor 320, the second pin being used for transmitting the first signal, and the third pin being used for transmitting the second signal, and the first pin being used for transmitting the first biological signal, so that the different functions of the transmitted signals can be distinguished by the setting of the plurality of pins, and the design complexity is reduced.

[0058] In some embodiments of the present specification, after receiving the first biological signal, the sensing signal converter 311 can determine whether to authorize the use permission of the remote control device 10 to the user corresponding to the first biological signal by comparing the first biological signal with the biological templates in the preset template library thereof, and can output a corresponding recognition result as a recognition signal. In other embodiments, the sensing signal converter 311 can output the recognition signal when it is determined that the use permission of the remote control device 10 is authorized to the user corresponding to the first biological signal. That is, if the first biological signal fails to match the biological templates in the preset template library, the sensing signal converter 311 can not output a signal to the controller 100.

[0059] Further, after receiving the recognition signal, the controller 100 can determine that the recognition signal indicates that the biological recognition is successful, and then the controller 100 can output a first control signal to the operation signal converter 312 to wake up the operation signal converter 312, if the use permission of the remote control device 10 needs to be authorized to the user corresponding to the first biological signal. Alternatively, the controller 100 can output the first control signal to the operation signal converter 312 after receiving the recognition signal, if the recognition signal is output by the sensing signal converter 311 when it is determined that the first biological signal matches the biological templates in the preset template library.

[0060] In order to limit the remote control device 10 and avoid other users from accidentally touching or operating the remote control device 10, the operation signal converter 312 in the embodiments of the present specification can send a second control signal to the biometric sensor 320 only when the first control signal is received, so as to receive the second biological signal returned by the biometric sensor 320 in response to the second control signal, and the second biological signal can be converted into an operation signal by the operation signal converter 312, without the need to set a separate key module to collect the operation of the user, thereby reducing the hardware design cost.

[0061] In some embodiments of the present disclosure, the data processing component 310 can further set a fourth pin and a fifth pin connection, the fourth pin and the fifth pin connection being connected to the biometric sensor 320, the fourth pin being used to transmit a second control signal, and the fifth pin being used to transmit a second biological signal. The setting of the plurality of pins can be used to distinguish the transmitted signals, and reduce the design complexity.

[0062] In some embodiments of the present disclosure, the biometric sensor 320 can be a fingerprint sensor. Further, the fingerprint sensor can be used to collect a fingerprint signal of a user, and the collected fingerprint signal can be transmitted to the data processing component 310 as a biological signal for signal conversion. In other embodiments, the biometric sensor 320 can also be a camera module, an iris sensor, etc., and the present disclosure does not limit the same.

[0063] Reference Figure 3 As shown in some embodiments of the present disclosure, the data processing component 310 can further include a memory 313 connected to the sensing signal converter 311. The sensing signal converter 311 is further configured to send the first biological signal to the memory 313 when it is determined that the identification signal is the same as the reference signal.

[0064] Further, the memory 313 can store a preset template library including biological templates. When the sensing signal converter 311 compares the first biological signal with the biological templates, it can read the biological templates from the template library in the memory 313, and compare the obtained biological templates with the first biological signal to determine whether the biological recognition is successful, and output a corresponding identification signal.

[0065] In the template library, a plurality of biological templates of different users can be included, and the users corresponding to the different biological templates can have different use permissions. Further, when the sensing signal converter 311 converts the first biological signal, the identification signal outputted can further include use permission information corresponding to the first biological signal. For example, different use permissions can be represented by different permission identifiers, and thus the identification signal can include the permission identifier corresponding to the first biological signal.

[0066] In the template library, the biological templates can be collected by the biometric sensor 320 and stored in the template library in the memory 313, or the biological templates can be collected by other devices, and the collection devices are connected to the remote control device 10 to write the biological templates into the memory 313.

[0067] Exemplarily, when the biometric template is collected by the biometric sensor 320, the biometric template signal collected by the biometric sensor 320 can be transmitted to the sensing signal converter 311 first, so as to pre-process the biometric template signal by the sensing signal converter 311 to obtain the biometric template, and then the sensing signal converter 311 can transmit the processed biometric template to the storage 313 for storage, thereby completing the entry of the biometric template. Further, after the biometric template is successfully entered, the use permission of the user corresponding to the biometric template can be set correspondingly.

[0068] In some embodiments of the present specification, the data processing assembly 310 can further include an encoder 314 connected to the sensing signal converter 311 and the storage 313; the encoder 314 is configured to encode the first biometric signal output by the sensing signal converter 311 and send the target biometric signal to the storage 313.

[0069] The encoder 314 can be an encryption module configured to encrypt the first biometric signal. Further, the encoder 314 can also be configured to encode (i.e., encrypt) the biometric template signal collected by the biometric sensor 320 or the biometric template obtained after pre-processing by the sensing signal converter 311, and then the encoder 314 can store the output encoded biometric template in the template library of the storage 313, thereby improving the security of the biometric template.

[0070] Correspondingly, the data processing assembly 310 can further include a decoder, and the sensing signal converter 311 can obtain the biometric template from the storage 313 through the decoder after receiving the first biometric signal. The decoder can decode the encrypted biometric template, and then the sensing signal converter 311 can compare the first biometric signal with the decoded biometric template to determine whether to authorize the use permission of the remote control device 10 to the user corresponding to the first biometric signal.

[0071] In some embodiments of the present specification, the biometric sensor 320 can include a plurality of sensing components 321 arranged in a one-dimensional array or a two-dimensional array, and the output ends of the plurality of sensing components 321 are connected to the sensing signal converter 311 and the operation signal converter 312.

[0072] It can be understood that the plurality of sensing components 321 can be arranged in a one-dimensional array along a first direction, and the plurality of sensing components 321 can also be arranged in a two-dimensional array along multiple directions. Further, the first biometric signal and the second biometric signal can include a plurality of sub-signals, and each sensing component 321 can output a corresponding sub-signal to the sensing signal converter 311 and the operation signal converter 312 when sensing the to-be-detected object.

[0073] Further, for the inductive signal conversion scene and the operation signal conversion scene, the processing of the sub-signals output by the plurality of sensing components 321 by the corresponding converters can be different. For example, in the inductive signal conversion scene, the inductive signal converter 311 can receive the sub-signals output by the plurality of sensing components 321, and can pre-process the plurality of sub-signals to obtain more accurate biological signals of the user, so as to improve the accuracy of biometric identification when comparing the biological signals with the biological template; in the operation signal conversion scene, the operation signal converter 312 focuses more on the collection or receiving time of different sub-signals, and by the order of collection or receiving of the plurality of sub-signals within a preset time length, the running path or displacement deviation of the biological signals at the plurality of sensing components 321 can be obtained, and then the operation signal converter 312 can convert the running path or displacement deviation obtained by processing into an operation signal and send it to the controller 100. Through the converters of the data processing assembly 310, different conversions of the biological signals can be realized, and then the user can be distinguished and the user operation can be recognized based on the collected biological signals, reducing the hardware design cost and the software design complexity.

[0074] In some embodiments of the present specification, the operation signal converter 312 or the memory 313 can also store a mapping table, which can include the mapping relationship between the displacement deviation of the sub-signals output by the plurality of sensing components 321 and the keys, i.e., based on the mapping table. Then, the operation signal converter 312 can directly read the mapping table from the internal storage or read the mapping table from the memory 313, and by looking up the table, the key function corresponding to the displacement deviation of the plurality of sub-signals can be determined, and the operation signal can be output based on the lookup result.

[0075] Further, the mapping table can include X-direction displacement, Y-direction displacement, key name and key value. By combining the X-direction displacement and the Y-direction displacement, a plurality of displacement deviations can be obtained, different displacement deviations can correspond to different key names, and different key names can correspond to different key values (KEY). For example, the mapping table can refer to Table 1.

[0076] Table 1

[0077] Key name X Y KEY Up selection key 0 1 96 Down selection key 0 -1 97 Left selection key -1 0 98 Right selection key 1 0 99 Confirm selection key 0 0 100 Back selection key 1 1 101

[0078] After the operation signal converter 312 determines the displacement deviation corresponding to the plurality of sub-signals in the second biological signal, the key name and the key value corresponding to the displacement deviation can be determined by querying Table 1 above, and the key value can be output as an operation signal to the controller 100.

[0079] Of course, it can be understood that the above Table 1 is an example of the mapping table provided in the embodiments of the present specification, and other contents can also be included in other embodiments, and the mapping table can also be represented in other forms, which is not limited in the present specification.

[0080] In some embodiments of the present specification, the device can further include a key part, the key part including at least one key, the at least one key being communicatively connected to the controller 100; the at least one key being configured to convert a pressing operation of the object to be detected into a pressing signal; and the controller 100 being configured to receive the pressing signal from the at least one key when determining that the identification signal is the same as the reference signal.

[0081] It can be understood that the remote control device 10 can also be provided with a key part, and after successful identification, i.e., when the controller 100 determines that the identification signal is the same as the reference signal, the pressing signal can be obtained from the key part to obtain the user's operation on the remote control device 10, and then the third control signal can be output to the electronic device in response.

[0082] Further, the controller 100 can send a signal to the key part to activate the key part when determining that the identification signal is the same as the reference signal, and then receive the pressing signal output by the key part. Alternatively, the key part is always in an activated state, and can send the pressing signal to the controller 100 when sensing the pressing operation of the user, and when the controller 100 determines that the identification signal is the same as the reference signal, the currently received pressing signal can be processed to output the third control signal.

[0083] In some embodiments of the present specification, the remote control device 10 can further include an indicator light part, the indicator light part being connected to the controller 100, and then different light signals can be output based on the control signal output by the controller 100 or different indicator lights can be controlled to output light signals.

[0084] The second aspect of the present specification provides a remote control system, including a remote control device 10 and an electronic device. The remote control device 10 includes a controller 100, a signal transceiver 200, and a biometric identification part 300, the biometric identification part 300 including a data processing assembly 310 and a biometric feature sensor 320; wherein the data processing assembly 310 includes an induction signal converter 311 and an operation signal converter 312.

[0085] The induction signal converter 311 and the operation signal converter 312 are connected to the biometric feature sensor 320, and the induction signal converter 311 and the operation signal converter 312 are communicatively connected to the controller 100, and the controller 100 is wirelessly connected to the electronic device through the signal transceiver 200.

[0086] The biometric sensor 320 is used to: acquire a first biosignal of the object to be detected and send the first biosignal to the sensing signal converter 311. The sensing signal converter 311 is used to: convert the first biosignal into an identification signal and send it to the controller 100. The controller 100 is used to: send a first control signal to the operation signal converter 312 after receiving the identification signal. The operation signal converter 312 is used to: send a second control signal to the biometric sensor 320 after receiving the first control signal; receive the second biosignal returned by the biometric sensor 320 and convert the second biosignal into an operation signal and send it to the controller 100. The controller 100 is also used to: send a third control signal to the electronic device via a signal transceiver after receiving the operation signal.

[0087] In some embodiments of this specification, the electronic device includes a display screen, a wireless transceiver, and a processor, wherein the display screen and the wireless transceiver are connected to the processor; the wireless transceiver is used to receive a third control signal sent by the signal transceiver 200 of the remote control device 10, and to send the third control signal to the processor; the processor is used to control the display screen to display after receiving the third control signal.

[0088] The specific composition and working principle of each component unit in the above embodiments can be referred to the relevant description above, and will not be repeated here.

[0089] The following is in conjunction with the appendix Figure 3 Using a biometric sensor 320 as a fingerprint sensor, an authorized user as an administrator, an unauthorized user as a child, and a television set as an electronic device, the workflow of the remote control system in this embodiment is described. This workflow may include a user fingerprint enrollment process, a user fingerprint recognition process, and a user gesture recognition process.

[0090] refer to Figure 3 As shown, the user can be controlled to enter the fingerprint enrollment process by operating the remote control device 10. At this time, multiple sensing components 321 of the fingerprint sensor detect the user's finger approaching, collect the user's fingerprint image, and send it to the induction signal converter 311. The induction signal converter 311 preprocesses the fingerprint image and encrypts it through the encoder 314 before storing it as a fingerprint template in the memory 313. The user can then set the fingerprint template as an administrator and assign usage permissions to the administrator through the operation of the remote control device 10, thus completing the fingerprint enrollment.

[0091] In the user fingerprint identification process, the plurality of sensing components 321 of the fingerprint sensor senses the approach of the finger of the current user, and can send a first signal to the sensing signal converter 311 to wake up the sensing signal converter 311. After the sensing signal converter 311 is woken up, a reset signal value can be output to the fingerprint sensor. The fingerprint sensor responds to the reset signal to control the plurality of sensing components 321 to collect a fingerprint image of the user as a first biological signal and send it to the sensing signal converter 311. After receiving the fingerprint image, the sensing signal converter 311 processes the fingerprint image to obtain the fingerprint features of the current user, reads the fingerprint template from the memory 313, decrypts the fingerprint template through the decoder, and compares the fingerprint template with the current fingerprint image. If it is determined that the two match, it can be determined that the current user is an administrator, and the current collected fingerprint image can be encrypted by the encoder 314 and stored as a template in the memory 313. If the sensing signal converter 311 determines that the two do not match, it can be determined that the current user is a child, and the fingerprint image does not need to be encrypted and stored. The sensing signal converter 311 can output an identification signal to the controller 100 based on the comparison result. The controller 100 can determine whether to authorize the remote control device 10 to use the permission for the current user based on the received identification signal. If the controller 100 determines that the current user is an administrator, it is determined that the remote control device 10 can be authorized to use the permission for the current user, and a control signal can be sent to the operation signal converter 312. At this time, the user collection identification process is entered.

[0092] In the user gesture identification process, the operation signal converter 312 can output a second control signal to the fingerprint sensor based on the received control signal to control the plurality of sensing components 321 of the fingerprint sensor to collect a set of fingerprint images within a preset time period and send the set of fingerprint images to the operation signal converter 312. At this time, the operation signal converter 312 can process the received set of fingerprint images, determine the sliding displacement deviation corresponding to the set of fingerprint images according to the coordinate parameters of the sensing components 321 corresponding to each image of the set of fingerprint images, and can query the mapping table based on the sliding position deviation to determine the key value corresponding to the sliding position deviation, and send the determined key value to the controller 100 as an operation signal. The controller 100 can output a third control signal according to the received key value and send it to the television through the signal transceiver 200. Further, the processor of the television controls the display screen to display after receiving the third control signal.
