[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on December 1, 2023, with application number 202311635842.X and application name “Infrared Remote Control Method and Terminal Device,” all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the field of terminals, and in particular relates to an infrared remote control method, electronic equipment, computer storage medium, and computer program product. Background Art

[0004] With the continuous development of the Internet of Things, smartphones and other terminal devices have become the most important mobile control method in smart home control systems. For example, users can remotely control a variety of home appliances such as lights, air conditioners, and TVs through remote control applications on their mobile phones.

[0005] In existing technologies, enabling infrared remote control of terminal devices requires the addition of additional circuit modules, which increases the cost and design complexity of the terminal devices. Furthermore, existing terminal devices have a narrow transmission angle for remote control. When using the remote control, the infrared transmitter of the terminal device must be aimed at the controlled device; otherwise, the signal transmitted by the terminal device will not be transmitted to the controlled device. Consequently, existing terminal devices still present inconvenience in controlling transmitted signals, impacting the user experience.

[0006] Summary of the Invention

[0007] The present invention discloses an infrared remote control method, electronic device, computer storage medium, and program product. The present invention implements infrared remote control functionality on electronic devices based on a TOF module, which can reduce the design complexity of electronic devices. The present invention can provide 360-degree omnidirectional remote control of controlled electronic devices.

[0008] TOF modules are widely used in various electronic devices to detect the distance of target objects. In some scenarios, terminal devices can use TOF modules for 3D imaging and face unlocking. The TOF module includes a transmitting end (such as an infrared light source), a receiving end, and a chip. The light source of the TOF module can be used to emit infrared light and may include an infrared light diode. The infrared light diode is used to emit infrared light. The receiving end can receive the infrared light reflected back by the infrared light diode after the object is projected. The chip can control the emission of infrared light and calculate the time difference between the transmission and reception of light, so that the distance of the object being photographed can be calculated. Therefore, the infrared light diode in the TOF module can be used as the infrared light emitter of the present application to realize the infrared remote control function of the electronic device.

[0009] Based on this, in a first aspect, the present application provides an infrared remote control method, which is applied to an electronic device, and the electronic device may include a TOF module and a processing chip. The TOF module includes a TOF sensor, a driver chip, and a light source for emitting an infrared light signal, and the driver chip is electrically connected to both ends of the light source. The infrared remote control method includes: at a first moment, controlling the light source to emit a first infrared light signal to the user, controlling the TOF sensor to collect image data, and performing face recognition based on the image data; at a second moment, in response to a user's click command or voice command, controlling the light source to emit a second infrared light signal to the controlled electronic device, or sending a control signal to the driver chip, so that the driver chip controls the light source to emit a second infrared light signal to the controlled electronic device; wherein the first moment is before the second moment.

[0010] It is understood that before a user uses an electronic device to perform infrared remote control of a controlled electronic device, that is, at a first moment, the user can control the light source to emit infrared light (i.e., a first infrared light signal) toward the user for facial recognition. If the user's facial recognition is successful, the infrared remote control function of the electronic device is unlocked. At a second moment, in response to a click instruction or voice instruction from the user, the light source can be controlled to emit infrared light of a predetermined frequency (i.e., a second infrared light signal) to the controlled electronic device, thereby enabling the infrared remote control function of the controlled electronic device. The aforementioned "click instruction" may refer to a click instruction generated by the user clicking on the remote control application of the electronic device, i.e., when the user clicks on the remote control application of the electronic device, the click instruction generated controls the light source to emit an infrared light signal. The aforementioned "voice instruction" may refer to a voice signal spoken by the user to the electronic device. For example, a user speaks a voice command to an electronic device (e.g., an air conditioner) (e.g., a voice command such as "Hello YOYO, adjust the air conditioner temperature to 26°C"), and the electronic device adjusts the air conditioner temperature after receiving the voice instruction.

[0011] The infrared remote control method of the present application can reuse the TOF module to transmit infrared remote control signals, thereby improving the operational convenience of the electronic device controlling the controlled electronic device, reducing the design complexity of the terminal device, and improving the user experience. The infrared remote control method of the present application uses a TOF module to implement infrared remote control. The TOF module is used for face recognition or detecting the distance of the target object. That is, the TOF module has a large-angle and high-power infrared light emission field. Therefore, it can solve the problem that traditional electronic devices must aim the infrared transmitter of the electronic device at the controlled electronic device to achieve infrared remote control due to low power and small remote control transmission angle.

[0012] As an optional solution, the electronic device also includes a processing chip. The processing chip includes a GPIO port, the driving chip includes a signal processing circuit, and the GPIO port of the processing chip is electrically connected to the signal processing circuit. The processing chip is configured to: at a second moment, in response to a user's click instruction or voice instruction, send a GPIO signal to the signal processing circuit through the GPIO port. The signal processing circuit is used to convert the GPIO signal into a driving signal, and the driving signal is used to drive the light source to emit a second infrared light signal to the controlled electronic device. Based on such a design, the electronic device of the present application does not need to add an additional circuit module, and the infrared remote control function is realized on the electronic device through the TOF module. There is no need for the TOF sensor to provide an LVDS signal. The processing chip of the electronic device can drive the light source to emit an infrared remote control signal of a predetermined frequency to the controlled electronic device by sending a GPIO signal to the driving chip, thereby realizing the infrared remote control function.

[0013] As an optional solution, the TOF sensor is used to: at a first moment, send a control signal to the driver chip; the driver chip is used to convert the control signal into a second drive signal. The second drive signal is used to drive the light source to emit a first infrared light signal to the user. Before the user uses the electronic device to perform infrared remote control of the controlled electronic device, that is, at the first moment, the user sends a control signal to the driver chip through the TOF sensor, so that the driver chip sends a second drive signal to the light source to drive the light source to emit infrared light (that is, the first infrared light signal) to the user for face recognition. As an optional solution, the electronic device also includes a processing chip and a first device, the first device is connected between the second end of the light source and the ground end, the processing chip is connected to the first end of the light source, the processing chip is also connected to the first device, and the first device can be configured to turn on or off the electrical connection between the processing chip and the light source. Based on such a design, its infrared remote control function can be realized by the processing chip and the first device.

[0014] As an optional solution, the processing chip is configured to: at a second moment, in response to the user successfully completing facial recognition and in response to the user's click command or voice command, control the switch tube to be in an on state during a first time period, and control the switch tube to be in an off state during a second time period. The first time period and the second time period constitute a switching cycle. Based on this design, the processing chip and switch tube of the present application can control the light source to emit an infrared light signal of a predetermined frequency, realizing various remote control functions of the controlled electronic device.

[0015] As an optional solution, the processing chip is used to power the light source when the switch tube is in the on state, so that the light source transmits an infrared light signal to the controlled electronic device. Based on this design, the processing chip and switch tube of the present application can control the light source to emit an infrared light signal of a predetermined frequency, thereby realizing various remote control functions of the controlled electronic device.

[0016] As a kind of alternative scheme, terminal equipment also includes processing chip and interface converter, and TOF sensor is connected with the first input of interface converter by the first bus and the second bus, and processing chip is connected with the second input of interface converter by the third bus and the fourth bus, and the output of interface converter is connected with driver chip by the fifth bus and the sixth bus.Based on such design, the terminal equipment of the present application can realize the switching between TOF function and remote control function by the control to interface converter.Alternatively, the first bus, the third bus and and the fifth bus are serial peripheral component bus, and the second bus, the fourth bus and the sixth bus are low voltage differential signal bus.

[0017] As an optional solution, the interface converter is used to connect the TOF sensor with the driver chip, or to connect the processing chip with the driver chip.

[0018] As an optional solution, the processing chip is also used to output a first switching signal to the interface converter in response to a user's click command or voice command, so that the interface converter connects the processing chip to the driver chip. The processing chip is also used to output a second switching signal to the interface converter in response to the user's camera command, so that the interface converter connects the TOF sensor to the driver chip. Based on such a design, the present application can achieve switching between the TOF function and the remote control function by controlling the interface converter.

[0019] In a second aspect, the present application further provides an electronic device, which includes a TOF module and a processing chip, and the processing chip is used to execute the infrared remote control method provided in the first aspect above.

[0041] In the embodiments of this application, terms such as "first" and "second" are used solely to distinguish between different objects and should not be construed as indicating or implying relative importance or order. For example, terms such as "first application" and "second application" are used to distinguish between different applications, not to describe a specific order of applications. Features defined as "first" or "second" may explicitly or implicitly include one or more of these features.

[0042] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0043] With the continuous development of the Internet of Things, electronic devices such as smartphones have become the most important mobile control method in smart home control systems. For example, users can remotely control a variety of home appliances such as lights, air conditioners, and TVs through remote control applications on their mobile phones.

[0044] As shown in Figure 1, an application scenario diagram of an electronic device 100a is shown. A user uses the electronic device 100a to remotely control a controlled electronic device 200a. The electronic device 100a is a mobile phone, and the controlled electronic device 200a is a television. Because the mobile phone is equipped with a separate infrared transmitter on the top or back side of the phone, the user can use the phone to remotely control the volume, playback channel, power on or off, and other functions of the television. However, the infrared transmitter is only used to realize the remote control function of the mobile phone, so the power of the infrared transmitter is low, and the remote control transmission angle of the infrared transmitter is also small. Therefore, when the user uses the electronic device 100a for remote control, the infrared transmitter of the electronic device 100a must be aimed at the controlled electronic device 200a. Otherwise, the infrared signal emitted by the electronic device 100a cannot be transmitted to the controlled electronic device 200a, and the remote control function cannot be realized. Therefore, the electronic device 100a still appears inconvenient in controlling the transmitted signal, which greatly reduces the user experience.

[0045] In order to solve the above problems, the present application provides an infrared remote control method, electronic device, computer storage medium and program product. The technical solution of the present application is based on a general time of flight (TOF) module, which can realize infrared remote control function on electronic devices, reduce the design complexity of electronic devices, realize 360-degree omnidirectional remote control, and enhance the user experience.

[0046] TOF, which literally means time of flight, is a 3D imaging method that uses a sensor to continuously transmit light pulses to a target. The sensor then receives the returned light and measures the distance to the target by measuring the round-trip time of the light pulses. The sensor calculates the time difference, or phase difference, between light emission and reflection to calculate the distance to the object, generating depth information. Combined with traditional camera imaging, the three-dimensional outline of the object can be displayed as a topographic map, with different colors representing different distances.

[0047] TOF modules are widely used in various electronic devices to detect the distance of target objects. In some scenarios, electronic devices can use TOF modules for 3D imaging and face unlocking. The following takes the electronic device as a mobile phone as an example for explanation. The TOF module can be set on the side of the screen of the mobile phone and / or on the side of the battery cover of the mobile phone. The TOF module may include a transmitting end (such as an infrared light source), a receiving end and a chip. The transmitting end of the TOF module can be used to emit infrared light and may include an infrared light diode. The receiving end can receive the infrared light reflected back after the infrared light is projected onto the object. The chip can control the emission of infrared light and calculate the time difference between the transmission and reception of light, so that the distance of the object being photographed can be calculated. Therefore, the infrared light diode in the TOF module can be used as an infrared light emitter in the embodiment of the present application to realize the infrared remote control function of the electronic device.

[0048] Typically, when a user needs to perform infrared remote control on a controlled electronic device, they can perform relevant operations on the electronic device so that the electronic device sends remote control commands to the controlled electronic device, thereby realizing the remote control function of the controlled electronic device. For example, the user can realize the remote control function of the controlled electronic device by operating a remote control application (Application, APP) on the electronic device.

[0049] When the user performs a first remote control operation (such as turning on a TV by remote control) on the remote control application of the electronic device, the electronic device sends a power-on instruction to the controlled electronic device through the TOF module, so that the controlled electronic device turns on after receiving the power-on instruction. When the user performs a second remote control operation (such as turning off the TV by remote control) on the remote control application of the electronic device, the electronic device sends a power-off instruction to the controlled electronic device through the TOF module, so that the controlled electronic device shuts down after receiving the power-off instruction. When the user performs a third remote control operation (such as adjusting the volume of the TV by remote control) on the remote control application of the electronic device, the electronic device sends a volume adjustment instruction to the controlled electronic device through the TOF module, so that the controlled electronic device adjusts the volume after receiving the power-off instruction. The user can remotely control multiple household appliances such as air conditioners, TVs, lamps or electric fans through the remote control application in the electronic device, which is easy to use and enhances the user experience.

[0050] Please refer to Figure 2, which illustrates an application scenario of an electronic device 100 according to one embodiment of the present application. It is understood that the technical solutions of the present embodiment can be applied to any infrared remote control scenario, such as mobile phones, tablet computers, personal computers, televisions, and other electronic devices that include a TOF module. The controlled electronic devices can be various household appliances such as lamps, air conditioners, televisions, and electric fans.

[0051] As shown in Figure 2, in a scenario, taking the electronic device 100 as a mobile phone and the controlled electronic device 200 as a TV as an example, the user lies on the sofa with the mobile phone in hand, and the mobile phone is not facing the TV, that is, the user can lie on the sofa and play with the mobile phone while watching TV programs.

[0052] At a certain moment, if the user wants to change the TV channel or adjust the volume, if the user does not change the angle of the current mobile phone (that is, the mobile phone does not need to be aimed at the infrared receiver of the TV), the user can still use the 360-degree omnidirectional infrared light field to remotely control the TV in the current posture and angle, which will greatly improve the user experience. Therefore, in the scenario shown in Figure 2, the electronic device 100 needs to perform 360-degree omnidirectional remote control of the controlled electronic device 200.

[0053] As shown in Figure 3, in another scenario, taking the electronic device 100 as a mobile phone and the controlled electronic device 200 as an air conditioner as an example, the user is eating at the dining table, and the user's mobile phone is placed on the coffee table 400. Since the dining table is a certain distance away from the coffee table 400, it is not convenient for the user to manually operate the remote control program of the mobile phone to remotely control the air conditioner. When the user wants to adjust the temperature of the air conditioner to a certain temperature (for example, 26°C), at this time, if the user says a voice command to the mobile phone (for example, the voice command can be "Hello YOYO, adjust the air conditioner temperature in the living room to 26°C"), the mobile phone adjusts the temperature of the air conditioner after receiving the voice command. In other words, if the user can remotely control the temperature of the air conditioner only through voice commands while dining, this will greatly enhance the user experience.

[0054] In another scenario, taking the electronic device 100 as a mobile phone and the controlled electronic device 200 as a TV as an example, the user is eating at the dining table, the user's mobile phone is placed on the coffee table 400, and the TV is playing a program. Since the dining table is a certain distance away from the coffee table 400, it is not convenient for the user to manually operate the mobile phone to remotely control the TV. When the user wants to change the channel of the TV or adjust the playback volume of the TV, at this time, if the user says a voice command to the mobile phone (for example, the voice command can be "Hello YOYO, adjust the TV volume to 15), the mobile phone will adjust the volume of the TV after receiving the voice command. In other words, if the user only needs to use voice commands to remotely control the TV while dining, this will greatly enhance the user experience.

[0055] Therefore, in the scenarios shown in FIG3 , the electronic device 100 needs to combine the user's voice commands to perform infrared remote control on the controlled electronic device 200 , making the control of home appliances more intelligent and convenient.

[0056] Please refer to Figure 4, which is a circuit diagram of a TOF module 10 provided in one embodiment of the present application. It can be understood that in this embodiment, the TOF module 10 can be applied to an electronic device 100, and the TOF module 10 can be used to sense the distance of an object.

[0057] The TOF module 10 may include a TOF sensor 11, a driver chip 12, and a light source 13. The light source 13 may serve as the transmitting end of the TOF module 10. The TOF module 10 also includes an optical lens (not shown in FIG4 ), and the optical lens and the TOF sensor 11 may serve as the receiving end of the TOF module 10. The TOF module 10 collects the light source reflected by the object through the optical lens and the TOF sensor 11.

[0058] The TOF sensor 11 is connected to the driver chip 12. In some specific implementations, the TOF sensor 11 can be connected to the driver chip 12 via a serial peripheral interface (SPI) bus and a low-voltage differential signaling (LVDS) bus. In one example, as shown in Figure 4, the TOF sensor 11 may include four SPI signal lines and four LVDS signal lines. The four SPI signal lines of the TOF sensor 11 may be a CSN1 signal line, an SCLK1 signal line, a MOSI1 signal line, and a MISO1 signal line. The four LVDS signal lines of the TOF sensor 11 may be an LDDP1 signal line, an LDDN1 signal line, an LDD-GATE1 signal line, and an LDD-XCLK1 signal line. The CSN1 signal line, the SCLK1 signal line, the MOSI1 signal line, and the MISO1 signal line of the TOF sensor 11 may all be electrically connected to the driver chip 12. The LDDP1 signal line, the LDDN1 signal line, the LDD-GATE1 signal line, and the LDD-XCLK1 signal line of the TOF sensor 11 may all be electrically connected to the driving chip 12 .

[0059] It is understood that the TOF sensor 11 can send LVDS differential signals to the driver chip 12 via the LDDP1 and LDDN1 signal lines, thereby controlling the light source 13 to emit infrared light through the driver chip 12. The TOF sensor 11 can also send enable signals to the driver chip 12 via the LDD-GATE1 and CSN1 signal lines, allowing the driver chip 12 to control laser emission and device selection. The TOF sensor 11 can also send clock signals to the driver chip 12 via the LDD-XCLK1 and SCLK1 signal lines, thereby achieving clock synchronization between laser emission and data sampling.

[0060] The TOF sensor 11 can be connected to a processing chip (not shown in FIG4 ). In some application scenarios, the TOF sensor 11 can respond to instructions from the processing chip and send an LVDS signal to the driver chip 12. After receiving the LVDS signal, the driver chip 12 generates a drive signal, which is used to drive the light source 13 to emit infrared light.

[0061] In this embodiment, the power pin LDVCC1 of the driver chip 12 is electrically connected to a first end of the light source 13 , and the ground pin LDGND of the driver chip 12 is electrically connected to a second end of the light source 13 .

[0062] It is understood that the light source 13 can be a laser. For example, in one implementation, the light source 13 can be a vertical-cavity surface-emitting laser (VCSEL). As an example, the power pin LDVCC1 of the driver chip 12 is electrically connected to the anode of the VCSEL, and the ground pin LDGND of the driver chip 12 is electrically connected to the cathode of the VCSEL. Alternatively, in another implementation, the light source 13 can be an edge-emitting laser (EEL).

[0063] In one usage scenario, when the user uses the TOF function of the electronic device 100, the TOF sensor 11 sends an LVDS signal to the driver chip 12, so that the driver chip 12 drives the light source 13 to emit infrared light, and the TOF sensor 11 can calculate the time difference or phase difference between light emission and reflection to convert the distance of the object to generate depth information, thereby realizing the 3D imaging and face unlocking functions of the electronic device 100.

[0064] In one usage scenario, when a user uses the remote control function of the electronic device 100, the TOF sensor 11 sends an LVDS signal to the driver chip 12. After receiving the LVDS signal from the TOF sensor 11, the driver chip 12 drives the light source 13 to transmit an infrared remote control signal of a predetermined frequency to the controlled electronic device 200. The controlled electronic device 200 receives the infrared remote control signal transmitted by the light source 13, decodes the work instruction included in the infrared light, and executes the remote control response operation corresponding to the work instruction. This realizes the remote control function of the electronic device 100.

[0065] When the TOF function of the electronic device 100 is turned on, the remote control function of the electronic device 100 cannot be used. When the remote control function of the electronic device 100 is turned on, the TOF function of the electronic device 100 cannot be used.

[0066] Please refer to FIG5 , which is a schematic diagram of an electronic device 100 provided in accordance with an embodiment of the present application.

[0067] The electronic device 100 may include a time-of-flight (TOF) module 10 and a processing chip 30. The TOF module 10 is electrically connected to the processing chip 30. The TOF module 10 may include a time-of-flight (TOF) sensor 11, a driver chip 12, and a light source 13. The TOF sensor 11 may include four SPI signal lines and four LVDS signal lines. The four SPI signal lines of the TOF sensor 11 may be a CSN1 signal line, an SCLK1 signal line, a MOSI1 signal line, and a MISO1 signal line, respectively. The four LVDS signal lines of the TOF sensor 11 may be an LDDP1 signal line, an LDDN1 signal line, an LDD-GATE1 signal line, and an LDD-XCLK1 signal line, respectively. The CSN1 signal line, the SCLK1 signal line, the MOSI1 signal line, and the MISO1 signal line of the TOF sensor 11 may all be electrically connected to the driver chip 12. The LDDP1 signal line, the LDDN1 signal line, the LDD-GATE1 signal line, and the LDD-XCLK1 signal line of the TOF sensor 11 may all be electrically connected to the driver chip 12. Alternatively, the processing chip 30 may be a system on chip (SOC) or an application processor (AP) in the electronic device 100. The processing chip 30 includes a general purpose input and output (GPIO) port GPIO1. The driver chip 12 includes a signal processing circuit 122. The GPIO1 of the processing chip 30 is electrically connected to the signal processing circuit 122.

[0068] The processing chip 30 can send a GPIO signal to the signal processing circuit 122 through the general input and output port GPIO1. The signal processing circuit 122 can receive the GPIO signal and convert the GPIO signal output by the processing chip 30 into a driving signal, so that the driving chip 12 can drive the light source 13 to emit infrared light of a predetermined frequency.

[0069] In one application scenario, when a user uses the TOF function of the electronic device 100, the TOF sensor 11 communicates with the driver chip 12 through the SPI signal line and sends an LVDS signal to the driver chip 12, which then controls the light source 13 to emit infrared light to the object being photographed.

[0070] In another application scenario, when the user uses the remote control function of the electronic device 100, the processing chip 30 starts working, and the processing chip 30 sends a GPIO signal to the signal processing circuit 122 through the general input and output port GPIO1. The signal processing circuit 122 receives the GPIO signal and converts it into a driving signal to drive the light source 13 to transmit an infrared remote control signal of a predetermined frequency to the controlled electronic device 200. The controlled electronic device 200 receives the infrared remote control signal emitted by the light source 13, and after decoding the working instruction included in the infrared light, executes the remote control response operation corresponding to the working instruction, thereby realizing the remote control function of the electronic device 100.

[0071] When the electronic device 100 of this embodiment is used, there is no need to add additional circuit modules. The infrared remote control function is realized on the electronic device through the TOF module. There is no need for the TOF sensor 11 to provide an LVDS signal. The processing chip 30 of the electronic device 100 can drive the light source 13 to transmit an infrared remote control signal of a predetermined frequency to the controlled electronic device by sending a GPIO signal to the driver chip 12, thereby realizing the infrared remote control function.

[0072] It can be understood that in an optional implementation, the electronic device of the present application can also remotely control the controlled electronic device in combination with the user's voice command. Specifically, the processing chip 30 can also respond to the user's voice command or click command, output the corresponding GPIO signal to the signal processing circuit 122 of the driver chip 12, and the signal processing circuit 122 converts the GPIO signal into a drive signal, thereby driving the light source 13 to emit infrared light. In other words, the electronic device 100 of the present application can combine the user's voice command to perform infrared remote control of the controlled electronic device 200, making the home appliance control more intelligent and convenient. Taking the application scenario shown in Figure 3 as an example, the processing chip 30 can respond to the user's first voice command (for example, the voice command can be "Hello YOYO, adjust the living room air conditioner temperature to 26°C"), output a first GPIO signal to the signal processing circuit 122 of the driver chip 12, and the signal processing circuit 122 converts the first GPIO signal into a first drive signal, thereby driving the light source 13 to emit infrared light, and infrared remotely control the temperature of the air conditioner to 26°C. Based on such a design, the electronic device 100 of the present application can remotely control the controlled electronic device in conjunction with the user's voice commands, thereby improving the user's experience.

[0073] Please refer to FIG6 , which is a schematic diagram of an electronic device 100 provided in another embodiment of the present application.

[0074] The difference from the electronic device 100 shown in the embodiment of FIG. 5 is that, as shown in FIG. 6 , the electronic device 100 in this embodiment may further include a first device 40 .

[0075] The processing chip 30 is connected to the first terminal of the light source 13, and the first device 40 is connected between the second terminal of the light source 13 and the ground terminal. The processing chip 30 is connected to the first device 40. The first device 40 is used to connect or disconnect the electrical connection between the processing chip 30 and the light source 13. In one optional implementation, the processing chip 30 includes a general-purpose input / output port GPIO1 and a power pin LDVCC2. The general-purpose input / output port GPIO1 of the processing chip 30 is electrically connected to the first terminal of the first device 40, the second terminal of the first device 40 is grounded, and the third terminal of the first device 40 is electrically connected to the second terminal of the light source 13 and the ground pin LDGND of the driver chip 12. The power pin LDVCC2 of the processing chip 30 is electrically connected to the first terminal of the light source 13 and the power pin LDVCC1 of the driver chip 12. It will be understood that in this embodiment, the first terminal of the first device 40 can serve as the control terminal of the first device 40. In other words, the general-purpose input / output port GPIO1 of the processing chip 30 can output a control signal to the first terminal of the first device 40, thereby controlling the state of the first device 40. For example, the control signal output by the general purpose input and output port GPIO1 of the processing chip 30 can be used to control the first device 40 to be in an on state or an off state.

[0076] It can be understood that the first device 40 can be any one of a metal oxide semiconductor field effect transistor (MOSFET), an insulated gate bipolar transistor (IGBT), a thyristor, a bipolar power transistor (bipolar power transistor) or a wide bandgap semiconductor field effect transistor, that is, the first device 40 can realize the function of turning on and off the electrical connection between the processing chip 30 and the light source 13, and this application does not make any specific limitations on this.

[0077] In this embodiment, the processing chip 30 can output a power supply voltage to the light source 13 through the power pin LDVCC2.

[0078] The infrared remote control function of the electronic device 100 in this embodiment may be implemented not by the TOF sensor 11 and the driver chip 12 , but by the processing chip 30 and the first device 40 .

[0079] When the user uses the TOF function of the electronic device 100, the general input and output port GPIO1 of the processing chip 30 does not output a control signal to the first end of the first device 40, that is, the first device 40 is in the off state at this time, and the TOF sensor 11 and the driver chip 12 start working. The TOF sensor 11 outputs an LVDS signal to the driver chip 12. After receiving the LVDS signal from the TOF sensor 11, the driver chip 12 drives the light source 13 to emit infrared light toward the object. In this way, the TOF sensor 11 can calculate the time difference or phase difference between the emission and reflection of the light to convert the distance of the object to generate depth information, thereby realizing the 3D imaging and face unlocking functions of the electronic device 100.

[0080] When a user uses the remote control function of the electronic device 100, the TOF sensor 11 and the driver chip 12 stop working, and the processing chip 30 starts working, and the processing chip 30 provides a power supply voltage to the light source 13. Specifically, during the first time period T1 of the switching cycle T, the general-purpose input / output port GPIO1 of the processing chip 30 outputs a first control signal to the first device 40 to control the first device 40 to turn on, the second terminal of the light source 13 is grounded, and the power supply voltage output by the processing chip 30 is supplied to the first terminal of the light source 13, so that the light source 13 transmits an infrared remote control signal to the controlled electronic device 200 during the first time period T1. During the second time period T2 of the switching cycle, the general-purpose input / output port GPIO1 of the processing chip 30 does not output a control signal to the first terminal of the first device 40, causing the first device 40 to turn off, thereby preventing the light source 13 from emitting infrared light to the controlled electronic device 200 during the second time period T2. The first time period T1 and the second time period T2 constitute a switching cycle T.

[0081] For example, the switching cycle of the first device 40 is 1 μs. The processing chip 30 controls the first device 40 to be on during a time period of 0-0.3 μs, and the processing chip 30 outputs a 5V voltage to the light source 13 through the power pin LDVCC2, so that the light source 13 transmits an infrared remote control signal to the controlled electronic device 200 during this time period. The processing chip 30 controls the first device 40 to be off during a time period of 0.3 μs-1 μs, so that the light source 13 does not transmit an infrared remote control signal to the controlled electronic device 200 during this time period. In other words, the processing chip 30 can control the first device 40 to be on or off during multiple switching cycles, so that the light source 13 can transmit an infrared remote control signal of a first frequency to the controlled electronic device 200. The controlled electronic device 200 receives the infrared remote control signal transmitted by the light source 13, decodes the working instruction included in the infrared remote control signal, and executes the remote control response operation corresponding to the working instruction, thereby realizing the first remote control function of the electronic device 100 on the controlled electronic device 200.

[0082] The processing chip 30 controls the first device 40 to be turned on during a time period of 0-0.4 μs, and the power supply pin LDVCC2 of the processing chip 30 outputs a voltage of 5 V to the light source 13, so that the light source 13 transmits an infrared remote control signal to the controlled electronic device 200 during this time period. The processing chip 30 controls the first device 40 to be turned off during a time period of 0.4 μs-1 μs, so that the light source 13 does not transmit an infrared remote control signal to the controlled electronic device 200 during this time period. In other words, the processing chip 30 can control the first device 40 to be turned on or off during multiple switching cycles, so that the light source 13 can transmit an infrared remote control signal of the second frequency to the controlled electronic device 200, thereby realizing the second remote control function of the electronic device 100 over the controlled electronic device 200.

[0083] It can be understood that the processing chip 30 can adjust the conduction time of the first device 40 in each switching cycle according to different remote control functions of the controlled electronic device 200, thereby adjusting the frequency of the infrared light sent by the light source 13 to the controlled electronic device 200.

[0084] Based on the embodiment shown in FIG6 , when a user uses the remote control function of the electronic device 100 , the processing chip 30 controls the first device 40 so that the processing chip 30 supplies power to the light source 13 , thereby realizing the remote control function of the electronic device.

[0085] Please refer to FIG. 7 , which is a schematic diagram of an electronic device 100 provided in another embodiment of the present application.

[0086] The difference from the electronic device 100 shown in the embodiment of FIG. 5 is that, as shown in FIG. 7 , the electronic device 100 in this embodiment may further include an interface converter 50 .

[0087] The processing chip 30 can be connected to the interface converter 50 via the SPI bus and the LVDS bus, and the TOF sensor 11 can be connected to the interface converter 50 via the SPI bus and the LVDS bus. The interface converter 50 can be connected to the driver chip 12 via the SPI bus and the LVDS bus.

[0088] The TOF sensor 11 may include four SPI signal lines and four LVDS signal lines. The four SPI signal lines of the TOF sensor 11 may be a CSN1 signal line, an SCLK1 signal line, a MOSI1 signal line, and a MISO1 signal line, respectively. The four LVDS signal lines of the TOF sensor 11 may be an LDDP1 signal line, an LDDN1 signal line, an LDD-GATE1 signal line, and an LDD-XCLK1 signal line, respectively. The CSN1 signal line, SCLK1 signal line, MOSI1 signal line, and MISO1 signal line of the TOF sensor 11 may all be electrically connected to the interface converter 50. The LDDP1 signal line, LDDN1 signal line, LDD-GATE1 signal line, and LDD-XCLK1 signal line of the TOF sensor 11 may all be electrically connected to the interface converter 50.

[0089] The processing chip 30 may include four SPI signal lines and four LVDS signal lines. The four SPI signal lines of the processing chip 30 may be a CSN2 signal line, an SCLK2 signal line, a MOSI2 signal line, and a MISO2 signal line, respectively. The four LVDS signal lines of the processing chip 30 may be an LDDP2 signal line, an LDDN2 signal line, an LDD-GATE2 signal line, and an LDD-XCLK2 signal line, respectively. The CSN2 signal line, the SCLK2 signal line, the MOSI2 signal line, and the MISO2 signal line of the processing chip 30 may all be electrically connected to the interface converter 50. The LDDP2 signal line, the LDDN2 signal line, the LDD-GATE2 signal line, and the LDD-XCLK2 signal line of the processing chip 30 may all be electrically connected to the interface converter 50.

[0090] The interface converter 50 may include four SPI signal lines and four LVDS signal lines. The four SPI signal lines of the interface converter 50 may be a CSN3 signal line, an SCLK3 signal line, a MOSI3 signal line, and a MISO3 signal line. The four LVDS signal lines of the interface converter 50 may be an LDDP3 signal line, an LDDN3 signal line, an LDD-GATE3 signal line, and an LDD-XCLK3 signal line. The CSN3 signal line, SCLK3 signal line, MOSI3 signal line, and MISO3 signal line of the interface converter 50 may all be electrically connected to the driver chip 12. The LDDP3 signal line, LDDN3 signal line, LDD-GATE3 signal line, and LDD-XCLK3 signal line of the interface converter 50 may all be electrically connected to the driver chip 12.

[0091] When a user uses the TOF function of the electronic device 100, the processing chip 30 outputs a control instruction to the interface converter 50, which then connects the TOF sensor 11 to the driver chip 12. In other words, the TOF sensor 11 communicates with the driver chip 12 via the interface converter 50. The TOF sensor 11 can output an LVDS differential signal to the driver chip 12. After receiving the LVDS differential signal from the TOF sensor 11, the driver chip 12 drives the light source 13 to emit infrared light toward the object being photographed, thereby realizing the TOF camera function of the electronic device 100.

[0092] When a user uses the remote control function of the electronic device 100, the processing chip 30 outputs a control command to the interface converter 50, which then establishes a connection between the processing chip 30 and the driver chip 12. In other words, the processing chip 30 establishes a communication connection with the driver chip 12 via the interface converter 11. The processing chip 30 can output an LVDS differential signal to the driver chip 12 via the interface converter 50. After receiving the LVDS differential signal from the processing chip 30, the driver chip 12 controls the light source 13 to transmit an infrared remote control signal of a predetermined frequency to the controlled electronic device 200, thereby implementing the infrared remote control function of the electronic device 100.

[0093] Based on the embodiment shown in FIG. 7 , when a user uses the TOF function or the remote control function of the electronic device 100 , the electronic device 100 can switch between the TOF function and the remote control function by controlling the interface converter 50 .

[0094] The following will be explained using the electronic device 100 in the embodiment shown in Figure 5 as an example. In response to the user using the remote control function of the electronic device 100, the processing chip 30 sends a GPIO signal to the signal processing circuit 122 in the driver chip 12. The signal processing circuit 122 converts the GPIO signal into a drive signal, so that the driver chip 12 drives the light source 13 to emit infrared light, thereby generating the radiation intensity of the infrared light field as shown in Figure 8, where the units of the X coordinate and the Y coordinate are both degrees, and the unit of the radiation intensity is W / sr.

[0095] Figure 9 shows an infrared light pattern emitted by the electronic device 100 according to the embodiment shown in Figure 5. Taking a mobile phone as an example, the electronic device 100 is placed flat on a table with its screen parallel to the XY plane. As shown in Figure 9, the optical axis of the infrared light field emitted by the mobile phone's TOF module will be along the Z axis.

[0096] As shown in Figure 10, taking the electronic device 100 in the embodiment shown in Figure 5 as an example, the electronic device 100 is located in a room, and the screen of the electronic device 100 can be placed on a table parallel to the XY plane. Wherein, the room has walls and a ceiling. Since the electronic device 100 of the present application adopts a TOF module to realize infrared remote control, the TOF module is used for face recognition or detecting the distance of the target object, that is, the TOF module has a large-angle and high-power infrared light emission field, thus solving the problem that the infrared emitter of the electronic device must be aimed at the controlled electronic device to realize infrared remote control due to low power and small remote control transmission angle of traditional electronic devices. In addition, the infrared light emitted by the TOF module of the electronic device 100 of the present application generates the radiation intensity of the infrared light field as shown in Figure 11 after being reflected by the walls and ceiling, which can realize 360-degree omnidirectional remote control of the controlled electronic device.

[0097] In one application scenario, taking the electronic device 100 in the embodiment shown in Figure 5 as an example, the electronic device 100 is a mobile phone, and the user holds the phone to remotely control the controlled electronic device. Figure 12 shows the light angle of the mobile phone's TOF module 10 and the relative position of the person. As can be seen from Figure 12, the infrared light emitted by the mobile phone's TOF module 10 will be reflected after it hits the human body.

[0098] As shown in Figure 13, taking the electronic device 100 as a mobile phone as an example, the user holds the mobile phone and is in a room. Among them, the room has walls, ceilings, and furniture. Since the electronic device 100 of the present application adopts a TOF module to realize infrared remote control, and the TOF module has the characteristics of a large-angle and high-power infrared light emission light field, the infrared light emitted by the TOF module of the electronic device 100 of the present application will cover all directions in the room after being reflected by surrounding objects such as the human body, walls, ceilings or furniture, and the infrared light emitted by the TOF module will generate the radiation intensity of the infrared light field as shown in Figure 14, which can realize 360-degree omnidirectional remote control of the controlled electronic device. In other words, taking the application scenario shown in Figure 2 as an example, using the electronic device 100 of the present application, even if the user is lying on the sofa playing with the mobile phone, the user does not need to align the electronic device 100 with the infrared receiver of the controlled electronic device to realize infrared remote control of the controlled electronic device 200, greatly improving the user experience.

[0099] The infrared light signal sent by the electronic device 100 to the controlled electronic device 200 includes multiple data packets, as shown in Figures 15 and 16. Each data packet may include a start bit, an address code, an inverse address code, a data code, and an inverse data code.

[0100] As shown in Figure 16, the bit width of a logic level "1" is 2.25ms, and the pulse duration is 560us. The bit width of a logic level "0" is 1.12ms, and the pulse duration is 560us. As shown in Figure 17, the bit width of the repetition code is 11.25ms, and the pulse duration is 9ms. The relationship between the data packet transmission frame rate, peak transmission power, and remote control distance is shown in Table 1.

[0101] Table 1

[0102] As can be seen from Table 1 above, the electronic device 100 of the present application can increase the emission peak power of the light source 13 by adjusting the data packet transmission frame rate of the infrared light signal, thereby increasing the infrared remote control distance of the electronic device 100 to the controlled electronic device 200.

[0103] By adopting the electronic device of the present application, there is no need to add additional circuit modules, and the infrared remote control function can be realized based on the TOF module of the electronic device. Based on the characteristics of the TOF module with a large angle and high power projected light field, the electronic device 100 of the present application can perform 360-degree omnidirectional remote control of the controlled electronic device by means of the reflection of infrared light by walls, ceilings, furniture and human bodies. The electronic device of the present application combines the user's voice command to perform infrared remote control on the controlled electronic device 200. The user only needs to simply say the voice command to the electronic device 100 to achieve 360-degree voice remote control without blind spots, which can intelligently and conveniently control the controlled electronic device 200 and can be widely used in various smart home scenarios. In addition, the electronic device 100 of the present application can also increase the remote control range of the electronic device 100 to the controlled electronic device 200 by adjusting the data packet transmission frame rate of the emitted infrared light signal, thereby increasing the peak transmission power, enhancing the flexibility and usability of the device function, and improving the user experience.

[0104] An embodiment of the present application further provides an infrared remote control method. The infrared remote control method can be applied to the electronic device 100. The infrared remote control method may include the following steps:

[0105] Step S171: at a first moment, control the light source to emit infrared light to the user, control the TOF sensor to collect image data, and perform face recognition based on the image data.

[0106] As can be understood, using the electronic device 100 shown in FIG5 as an example, at the first moment, the processing chip 30 controls the light source 13 to emit infrared light toward the user, and the TOF sensor 11 can collect image data and perform facial recognition based on the image data. Therefore, the processing chip 30 determines whether to unlock the electronic device based on the facial recognition result. If unlocking is successful, the user can use the electronic device 100 to perform infrared remote control of the controlled electronic device 200.

[0107] Step S172, at the second moment, in response to a click instruction or voice instruction of the user, controlling the light source to emit infrared light of a predetermined frequency to the controlled electronic device, so as to perform infrared remote control on the controlled electronic device.

[0108] At the second moment, the processing chip 30 obtains the user's click command or voice command, controls the light source 13 to emit a second infrared light signal to the controlled electronic device 200, or sends a GPIO signal to the signal processing circuit 122 of the driving chip 12. The signal processing circuit 122 converts the GPIO signal into a driving signal, which can control the light source 13 to emit infrared light of a predetermined frequency to the controlled electronic device 200.

[0109] Optionally, the click instruction refers to a control instruction generated after the user clicks on a remote control application of the electronic device 100. The voice instruction is a voice command spoken by the user to the electronic device 100.

[0110] The controlled electronic device 200 receives the infrared light emitted by the light source 13, decodes the working instruction included in the infrared light, and then executes the remote control response operation corresponding to the working instruction.

[0111] The infrared remote control method and electronic device of the present application realize the multiplexing of TOF modules to transmit infrared remote control signals, thereby improving the operational convenience of electronic devices controlling controlled electronic devices, reducing the hardware cost of electronic devices, and not affecting the layout of other components of electronic devices, and can also enhance the user experience.
