Description

Technical Field

[0001] The present application relates to the field of signal transmission technology, and in particular to a device control method, system, electronic device and computer storage medium. Background Art

[0002] Audio interface protocols define the transmission format of audio data. Device manufacturers produce audio interfaces for various audio devices according to these standards. The audio interface's transceiver module receives and transmits audio data between the controlling device (i.e., master) and the controlled device (i.e., slave), implementing the protocol's requirements. This facilitates the transmission of digital audio signals between devices.

[0029] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field should fall within the scope of protection of the embodiments of the present application.

[0030] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. As used in this application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0031] It should be understood that although the terms first, second, third, etc. may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0032] The acquisition, processing, and transmission of digital audio data are crucial components of multimedia technology. Numerous digital audio systems, such as digital audio cassettes and digital sound processors, have entered the consumer market. For equipment and manufacturers, standardized information transmission structures can improve system adaptability.

[0033] Audio interface protocols define the transmission format of audio data. Device manufacturers produce audio interfaces for various audio devices according to these standards. The audio interface transceiver module receives and transmits audio data according to the protocol, enabling the transmission of digital audio signals between devices. Different audio signal processing methods and formats are required to meet different needs, resulting in different digital audio interfaces. Digital audio interfaces can be categorized as control interfaces or data interfaces based on the type of signal being transmitted. Control devices transmit audio data streams to controlled devices via data interfaces (such as I2S interfaces) while controlling devices configure controlled devices and monitor system status via control interfaces (such as IIC and SPI interfaces).

[0034] In order to transmit data signals and control signals at the same time, the interface bus SoundWire (MIPI's interface protocol for transmitting audio signals) is currently proposed. The data signal and control signal are transmitted simultaneously by using a smaller part of each frame of the signal to transmit the control signal and the remaining part to transmit the data signal.

[0035] Specifically, the interface bus Soundwire uses 48 bits in each signal frame to transmit control signals, and the remaining bits are used to transmit data signals. For signal frames, the shortest signal frame is 48 bits*2 in size, but the transmission efficiency of using the shortest signal frame for signal transmission is too low, and larger signal frames are usually used for data transmission, such as 256*16. In this case, the transmission of data signals far exceeds that of control signals. At the same time, the size of 48 bits is too small for transmitting control signals, and the control signals transmitted in each signal frame are too few, resulting in a corresponding decrease in the control efficiency of the controlled device. Therefore, this solution proposes a device control method and system to solve the above problems.

[0036] The following, in conjunction with the accompanying drawings, clearly and completely describes the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0037] Device control method

[0038] Figure 1 This is a device control method according to an embodiment of the present application. Figure 1 As shown, the device control method applied to the control device includes the following steps:

[0039] Step 101: Determine the bit position of the start signal edge of the signal frame corresponding to the clock signal.

[0040] To control a controlled device, the starting signal edge of the signal frame, such as the rising or falling edge, and the bit position corresponding to the clock signal are first determined. A rising edge is the moment when the signal level changes from a low level (digital "0") to a high level (digital "1"), and a falling edge is the moment when the signal level changes from a high level (digital "1") to a low level (digital "0"). Clock signals include a frame clock signal (WCK) and a bit clock signal (BCK). The rising or falling edge of the frame clock signal can be used as a reference position for the bit position. The bit position can be the reference position or a position that is separated from the reference position by at least one bit clock signal cycle.

[0041] In addition, the starting signal edge of the control signal in the signal frame is opposite to the starting signal edge of the data signal in the signal frame. The control signal in at least one bit corresponding to the clock signal constitutes a control instruction, and the remaining control signals constitute control information. The control instruction is used to indicate the type of the control signal in the signal frame, and the control information is used to indicate the content of the control signal in the signal frame.

[0042] For example, the first three bits of the control signal corresponding to the clock signal can be set to form a control instruction. The control instruction can indicate the type of the control signal in the signal frame, such as a reset instruction, a start instruction, a mute instruction, etc. The remaining control signals describe the control operation that the control device needs to perform on the controlled device. For example, when the control instruction indicates that the type of the control signal in the signal frame is a monitoring instruction, the remaining control signals are used to indicate the specific content that the controlled device needs to monitor.

[0043] At the same time, the control signal and the data signal can be input alternately. For example, the control signal can be input first, then the data signal, and then the control signal, and this input method can be repeated so that the control signal and the data signal are alternately input in the signal frame.

[0044] The device control timing diagram can be as follows Figure 2 As shown, in Figure 2 In the example, the signal frame uses the falling edge of the frame clock signal as the reference position of the corresponding bit position, and the position at an interval of three bit clock signal cycles is used as the bit position. In the signal frame, the first three control signals and data signals constitute the control instructions. After receiving the signal frame, the controlled device parses it and feeds back the signal to the controlling device.

[0045] Step 102: Send a signal frame and a clock signal to at least one controlled device according to the bit position.

[0046] After determining the bit position, the control device sends a signal frame and a clock signal to at least one controlled device. Since the control signal and the data signal are input alternately, when the control signal corresponds to the rising edge of the bit clock in the clock signal, the data signal corresponds to the falling edge of the bit clock in the clock signal, and vice versa. Therefore, the clock signal can instruct at least one controlled device to parse the signal frame according to the start signal edge.

[0047] In an embodiment of the present application, by configuring a portion of the control signal to form a control instruction, and using the remaining control signal to transmit the control information to the controlled device, the register in the controlled device can be replaced. When performing the same control operation on different controlled devices, there is no need to send different instructions, thereby improving the control efficiency of the device. By alternately inputting the control signal and the data signal in the signal frame, the signal quantity of the transmitted control signal can be guaranteed, thereby enabling the timely transmission of the control signal. In addition, since the bit position corresponding to the starting signal edge of the signal frame can be determined by the clock signal, the signal frame can be flexibly configured, increasing the adaptability of the signal frame to various communication protocols.

[0048] In a possible implementation, when the control instruction indicates that the type of the control signal is a monitoring signal, a feedback signal sent by the controlled device is received, and the feedback signal is parsed according to the clock signal.

[0049] When the control instruction indicates that the control signal type is a monitoring signal, the controlled device will feedback a signal to the control device after parsing the signal frame. The control device can then parse the feedback signal based on the clock signal. For example, the control device can parse the control signal from the controlled device feedback signal based on the rising edge of the clock signal in the clock signal, and parse the data signal from the controlled device feedback signal based on the falling edge of the clock signal in the clock signal.

[0050] It should be noted that the control device can also parse the control signal in the feedback signal of the controlled device according to the falling edge of the bit clock signal, and parse the data signal in the feedback signal of the controlled device according to the rising edge of the bit clock signal in the clock signal, which is not limited here.

[0051] In the embodiment of the present application, during the monitoring process, the control device analyzes the feedback signal through the clock signal and can monitor the status of the controlled device in real time.

[0052] In one possible implementation, the control signal and the data signal may correspond to the same number of bits of the clock signal.

[0053] For example, each control signal and data signal may be set to correspond to a 48-bit clock signal.

[0054] In the embodiment of the present application, by setting the control signal and the data signal to have the same number of bits corresponding to the clock signal, the transmission frequency of the control signal can be made the same as the transmission frequency of the data signal, thereby ensuring the transmission rate of the control signal.

[0055] In a possible implementation, control signals and data signals of multiple controlled devices may be respectively encapsulated into signal frames as multiple signal transmission channels.

[0056] The clock signal instructs each controlled device to interpret the control signal or data signal of the corresponding signal transmission channel.

[0057] For example, if the control device needs to monitor the controlled devices, the control device can send signal frames and clock signals to n controlled devices, where n is a positive integer greater than 2, such as Figure 3 As shown, the control device can distribute control signals and data signals to multiple channels, send signal frames to the controlled device through the data line in the audio interface, and send clock signals through the frame clock line and bit clock line in the audio interface. After receiving the signal frame and clock signal, the controlled device parses the signal frame and feeds back the signal to the control device.

[0058] It should be noted that the feedback signal of the controlled device also includes a data signal and a control signal. The control signal and data signal in the feedback signal of the controlled device are interrupt signals or status signals that feed back the control signal sent by the control device.

[0059] The control signal can be a binary signal, composed of signals of various bits. For example, the control signal can be a binary signal such as 001, 1001, 10101, and different control signals can be configured as universal control instructions, such as reset instructions, start instructions, mute instructions, and other control instructions, which can control different types of controlled devices. At the same time, vacant bits can be flexibly set in the control signal. The vacant bits have no effect on the content of the control instructions, but can change the length of the control signal. Because the control signal is a binary signal, the control signal can be adapted to a variety of different controlled devices. In addition, vacant bits can be set to flexibly adjust the length of the control signal, further improving the adaptability of the control signal.

[0060] For another example, if the control device only needs to control the controlled device, the control device can also send signal frames and clock signals to n controlled devices, where n is a positive integer greater than 2. Figure 3 The difference between the timing diagram shown is that no feedback signal from the controlled device is required, so only one data line is needed. The specific timing diagram is as follows Figure 4 shown.

[0061] In an embodiment of the present application, the control signals and data signals of multiple controlled devices are respectively used as multiple signal transmission channels and encapsulated into signal frames, so that the control device can control multiple controlled devices at the same time, and within one frame, the control device sends control information to the controlled devices through different channels to perform synchronous control of the controlled devices.

[0062] In a possible implementation, each signal transmission channel may correspond to the same number of bits of the clock signal.

[0063] The signal transmission channels used to send signal frames and clock signals to each controlled device may correspond to the same number of bits of the clock signal. For example, the signal transmission channels may all correspond to 576 bits of the clock signal.

[0064] In the embodiment of the present application, by setting each signal transmission channel to correspond to the same number of bits of the clock signal, it is possible to avoid excessive restrictions on the number of signal frame bits due to different channel lengths.

[0065] Existing audio control interfaces typically involve the controller selecting the device address (e.g., IIC, soundwire) or port (e.g., SPI) of the controlled device to match the controlled device, and then performing read and write operations on the controlled device's registers. The signal frame transmission rate is relatively slow.

[0066] In a possible implementation, each controlled device may correspond to a signal transmission channel.

[0067] By setting each controlled device to correspond to a signal transmission channel, the device address of the controlled device can be bound to the signal transmission channel corresponding to the controlled device and matched with the controlled device. When transmitting signal frames to the controlled device, they can be transmitted directly.

[0068] In the embodiment of the present application, by setting each controlled device to correspond to a signal transmission channel, the need to select the device address of the controlled device and perform a matching process each time a signal is transmitted to the controlled device is avoided, thereby improving the transmission rate of the signal frame.

[0069] In one possible implementation, there may be a preset number of bits of the clock signal between the start signal edge of the control signal of at least one controlled device and the start signal edge of the signal frame, and the preset number of bits may indicate a control signal transmission mode of the signal frame.

[0070] Since the requirements of various communication protocols are different, in order to achieve compatibility, it is necessary to set a preset number of bits with a clock signal between the start signal edge of the control signal and the start signal edge of the signal frame. For example, the IIC protocol requires a preset number of bits of a bit clock cycle. Compatibility is only achieved if a bit of a bit clock cycle is set between the start signal edge of the control signal and the start signal edge of the signal frame.

[0071] In the embodiment of the present application, by setting a preset number of bits of a clock signal between the start signal edge of the control signal and the start signal edge of the signal frame, the transmitted control signal can be adapted to various communication protocols.

[0072] Figure 5 This is another embodiment of the device control method of the present application, such as Figure 5 As shown, the device control method for the controlled device includes the following steps:

[0073] Step 401: Receive a signal frame and a clock signal sent by a control device.

[0074] The controlled device receives a signal frame and a clock signal sent by the controlling device. The starting signal edge of the control signal in the signal frame is opposite to the starting signal edge of the data signal in the signal frame. The control signal in at least one bit corresponding to the clock signal constitutes a control instruction, and the remaining control signals constitute control information. The control instruction is used to indicate the type of the control signal in the signal frame, and the control information is used to indicate the content of the control signal in the signal frame.

[0075] The control signal and the data signal can be input alternately. For example, the control signal can be input first, then the data signal, and then the control signal, and this input method can be repeated so that the control signal and the data signal are alternated in the signal frame.

[0076] Step 402: Determine the starting signal edge of the signal frame according to the bit position of the clock signal.

[0077] The clock signal includes a frame clock signal and a bit clock signal. The controlled device determines the starting signal edge reference position of the signal frame according to the frame clock, and determines the starting signal edge of the signal frame according to the bit clock signal and the reference position.

[0078] Step 403: parse the signal frame according to the start signal edge to obtain the control signal and the data signal.

[0079] The starting edge of the control signal in a signal frame is opposite to the starting edge of the data signal in the signal frame, and the control signal and data signal are input alternately. Therefore, when the control signal corresponds to the rising edge of the bit clock in the clock signal, the data signal corresponds to the falling edge of the bit clock in the clock signal. The controlled device parses the signal frame to obtain the control signal and data signal. The control signal and data signal constitute the control instruction, which can include monitoring instructions or control operation instructions. When the control instruction is a monitoring instruction, the controlled device needs to feedback the signal to the controlling device.

[0080] In the embodiment of the present application, the controlled device can fully receive the control instructions from the control device by receiving signal frames in which the control signal and the data signal are alternately input, thereby improving the control efficiency of the control device.

[0081] In a possible implementation, the control signal and the data signal have the same number of clock signal bits.

[0082] It should be noted that, in order to further improve the accuracy of signal transmission, the control signal and data signal in each channel have the same number of clock signal bits.

[0083] In the embodiment of the present application, by setting the control signal and the data signal to have the same number of clock signal bits, it is possible to ensure that the signal is sent correctly and the controlled device switches to receiving in a timely manner after sending.

[0084] In one possible implementation, the process of parsing the signal frame according to the start signal edge to obtain the control signal and the data signal may also include: parsing the signal frame according to the start signal edge and the clock signal to obtain the control signal and the data signal; when the control instruction indicates that the type of the control signal is a monitoring signal, feeding back a feedback signal corresponding to the control signal and the data signal in the next frame of the signal frame.

[0085] The controlled device can parse the signal frame based on the start signal edge and the clock signal to obtain the control signal and the data signal. For example, the controlled device can parse the control signal in the signal frame based on the rising edge of the mid-clock signal in the clock signal, and parse the data signal in the signal frame based on the falling edge of the mid-clock signal in the clock signal. When the control instruction indicates that the control signal is of the monitoring signal type, the controlled device can feedback a feedback signal corresponding to the control signal and the data signal in the next frame after receiving the signal frame. The feedback signal can also include the control signal and the data signal. The control signal and the data signal in the feedback signal of the controlled device are interrupt signals or status signals that provide feedback on the control instruction composed of the control signal and the data signal sent by the control device.

[0086] In an embodiment of the present application, the controlled device parses the signal frame according to the start signal edge and the clock signal, so that the control device can realize real-time control of the controlled device. After receiving the signal frame, the controlled device parses the signal frame in the current frame of the received signal frame and feeds back the signal to the control device in the next frame, so that the control device can monitor the controlled device in a timely manner.

[0087] In a possible implementation manner, the controlled device may also report status information to the controlling device or report interruption information to the controlling device according to the control signal.

[0088] When the control signal indicates that the type of the control instruction is a monitoring instruction, the controlled device reports status information to the controlling device or reports interrupt information to the controlling device.

[0089] In the embodiment of the present application, the controlled device can notify the control device that further operations can be performed by reporting status information. The controlled device can notify the control device to monitor events and suspend the current operation state by reporting interrupt information.

[0090] Equipment control system

[0091] Figure 6 Schematic diagram of a device control system according to an embodiment of the present application. Figure 6 As shown, the device control system 500 includes: a control device 501 and a controlled device 502.

[0092] The control device 501 includes a first audio interface 503, which is used to determine the starting signal edge of the signal frame and the bit position corresponding to the clock signal, wherein the starting signal edge when the signal frame is a control signal is opposite to the starting signal edge when the signal frame is a data signal. The control signal in at least one bit corresponding to the clock signal constitutes a control instruction, and the remaining control signals constitute control information. The control instruction is used to indicate the type of the control signal in the signal frame, and the control information is used to indicate the content of the control signal in the signal frame. According to the bit position, the signal frame and the clock signal are sent to at least one controlled device 502, and the clock signal instructs at least one controlled device 502 to parse the signal frame according to the starting signal edge.

[0093] To perform operations such as controlling the controlled device 502, the starting signal edge of the signal frame, such as a rising edge or a falling edge, and the bit position corresponding to the clock signal are first determined. A rising edge is the moment when the signal level changes from a low level (digital "0") to a high level (digital "1"), and a falling edge is the moment when the signal level changes from a high level (digital "1") to a low level (digital "0"). The clock signal includes a frame clock signal and a bit clock signal. The rising edge or the falling edge of the frame clock signal can be used as a reference position for the bit position. The bit position can be the reference position or a position that is at least the number of bit clock signal cycles after the reference position.

[0094] In addition, the starting signal edge of the control signal in the signal frame is opposite to the starting signal edge of the data signal in the signal frame. The control signal in at least one bit corresponding to the clock signal constitutes a control instruction, and the remaining control signals constitute control information. The control instruction is used to indicate the type of the control signal in the signal frame, and the control information is used to indicate the content of the control signal in the signal frame.

[0095] For example, the first three bits of the control signal corresponding to the clock signal can be set to form a control instruction. The control instruction can indicate the type of the control signal in the signal frame, such as a reset instruction, a start instruction, a mute instruction, etc. The remaining control signals describe the control operation that the control device needs to perform on the controlled device. For example, when the control instruction indicates that the type of the control signal in the signal frame is a monitoring instruction, the remaining control signals are used to indicate the specific content that the controlled device needs to monitor.

[0096] At the same time, the control signal and the data signal can be input alternately. For example, the control signal can be input first, then the data signal, and then the control signal, and this input method can be repeated so that the control signal and the data signal are alternately input in the signal frame.

[0097] After determining the bit position, the control device 501 sends a signal frame and a clock signal to at least one controlled device 502 . The clock signal instructs the at least one controlled device 502 to parse the signal frame according to the start signal edge.

[0098] The controlled device 502 includes a second audio interface 504, which is used to receive the signal frame and clock signal sent by the control device 501, determine the starting signal edge of the signal frame according to the bit position of the clock signal, and parse the signal frame according to the starting signal edge to obtain a control signal and a data signal, wherein the starting signal edge when the signal frame is a control signal is opposite to the starting signal edge when the signal frame is a data signal.

[0099] The schematic diagram of the equipment control system communication is as follows Figure 7 As shown, the first audio interface 503 and the second audio interface 504 may include a clock line and a data line, wherein the clock line may include a frame clock line and a bit clock line, and the data line may include a control device data line and a controlled device data line. The control device data line is used to control the device 501 to transmit a signal to the controlled device 502. When the control instruction is a monitoring instruction, the controlled device 502 can feedback a signal to the control device 501 according to the controlled device data line.

[0100] In the embodiment of the present application, by configuring a portion of the control signal to form a control instruction, and using the remaining portion of the control signal to transmit the control information to the controlled device 502, the register in the controlled device 502 can be replaced. When performing the same control operation on different controlled devices 502, there is no need to send different instructions, thereby improving the control efficiency of the device. By alternately inputting the control signal and the data signal in the signal frame, the signal quantity of the transmitted control signal can be guaranteed, thereby enabling the timely transmission of the control signal. In addition, because the bit position corresponding to the starting signal edge of the signal frame can be determined by the clock signal, the signal frame can be flexibly configured, increasing the adaptability of the signal frame to various communication protocols.

[0101] It should be noted that the information interaction, execution process, etc. between the control device 501 and the controlled device 502 in the above-mentioned device control system are based on the same concept as the aforementioned device control method embodiment. The specific content can be found in the description of the aforementioned device control method embodiment and will not be repeated here.
