[0062] Please see Figure 1 , Figure 1 The schematic diagram illustrates the structure of a gateway device provided in some embodiments of the present invention.
[0063] like Figure 1As shown, the gateway device 10 includes a device housing 11, a gateway main circuit 12, and an interaction integration module 13, with the gateway main circuit 12 and the interaction integration module 13 installed inside the device housing 11.
[0064] Specifically, the gateway main circuit 12 includes a gateway controller 121, a wired communication circuit 122 and a wireless communication circuit 123. The gateway controller 121 is electrically connected to the wired communication circuit 122 and the wireless communication circuit 123 respectively. The gateway controller 121 is provided with a first UART interface 1211.
[0065] The interactive integration module 13 includes a power supply circuit 131, a main control chip 132, a voice processing circuit 133, and an infrared processing circuit 134. The power supply circuit 131 is electrically connected to the main control chip 132, the voice processing circuit 133, and the infrared processing circuit 134. The main control chip 132 is electrically connected to the voice processing circuit 133 and the infrared processing circuit 134. The main control chip 132 is provided with a second UART interface 1321. The main control chip 132 is electrically connected to the gateway controller 121 through the second UART interface 1321 and the first UART interface 1211.
[0066] In some embodiments, the interactive integration module 13 further includes a key processing unit ( Figure 1 (Not shown in the image), the button processing unit directly uses physical buttons or touch buttons to trigger input to control the operation of the voice processing circuit 133, such as mute, volume up / down, microphone on, and microphone off. The button processing unit is designed to assist the voice processing circuit 133. In some specific business scenarios, button functions can be used to operate voice functions, such as on / off, volume up / down, and mute. After detecting external button input, the button processing unit generates button values, which are then sent to the main control chip 132 to schedule the voice processing circuit 133 for processing, achieving the effect of button-controlled voice functionality.
[0067] The main control chip 132 is the core component of the interactive integration module 13. It is responsible for processing the function instructions of all other components, handling the operation and scheduling of voice, infrared, button, and UART interface functions, and also managing memory, storage, loading drivers, running the operating system and application functions. The main control chip 132 integrates a CPU, memory unit, storage unit, and necessary input / output interfaces, including at least a UART interface (i.e., a second UART interface), an IR interface, an audio input interface SPI, a USB interface, and an audio output interface I2S.
[0068] In some embodiments, please refer to Figure 2 The main control chip 132 adopts such as Figure 2The communication chip U4 shown is connected to the voice processing circuit 133 through pins 4-7 (i.e., the first communication interface 101). The communication chip U4 can also be connected to the voice processing circuit 133 through pins 13 and 14 (i.e., the second communication interface 102). The communication chip U4 can be used to transmit control information or commands, voice signals and infrared signals, etc.
[0069] Specifically, pin 1 of communication chip U4 is grounded; pin 2 is connected to the first terminal of fuse FB, the first terminal of first capacitor C1, the first terminal of second capacitor C2, and the first terminal of first resistor R1; the second terminal of fuse FB is connected to power supply VCC; the second terminals of first capacitor C1 and second capacitor C2 are both grounded; pin 3 of communication chip U4 is connected to the second terminal of first resistor R1 and the first terminal of third capacitor C3, with the second terminal of third capacitor C3 grounded; pin 16 of communication chip U4 is connected to the first terminal of second resistor R2, with the second terminal of second resistor R2 grounded; and pin 26 of communication chip U4 is connected to the first terminal of third resistor R3, with the second terminal of third resistor R3 grounded.
[0070] In some embodiments, the power supply circuit 131 employs a DC / DC (direct current to direct current) circuit, and its conversion result mainly depends on the operating voltage of the main control chip 132. Additionally, the input power of the power supply circuit 131 must be at least 7.5W (5V*1.5A).
[0071] The interactive integration module 13 is an integrated hardware circuit unit that integrates functions such as voice acquisition, voice playback, and infrared control. Its external interfaces include a voice interface, an infrared interface, and a UART communication interface (i.e., a second UART interface). The voice interface includes a voice acquisition unit and a voice playback unit. The voice acquisition unit uses microphone elements, which can be added or removed according to business scenario requirements. The voice playback unit uses a speaker or loudspeaker element. This invention adopts a dual-channel output design, which can be designed as mono or multi-channel output according to actual business scenario requirements. The audio signal data acquired by the voice acquisition unit and the echoed voice signal data played by the voice playback unit are processed by the voice processing circuit 133 to filter out the true voice signal input data, and then transmitted through the main control chip 132 via the second UART interface. The audio data played by the voice playback unit is also received by the main control chip 132 through the second UART interface, processed by the voice processing circuit 133, and then played as audio signal data.
[0072] As a communication interface for interacting with control devices and smart devices (such as home appliances), the infrared interface is mainly controlled by the infrared processing circuit, which can both output and receive infrared code data.
[0073] The second UART interface serves as a direct channel for transmitting voice signal data and infrared control data, acting as a bridge for interaction with the gateway controller 121. The second UART interface operates in TX / RX full-duplex mode, requiring support for a baud rate of at least 1 Mbps. Primarily responsible for processing and transmitting voice and infrared data, the second UART interface possesses high-speed data processing and transmission capabilities. Employing a multi-level buffering mechanism and collaborating with the main control chip 132, the second UART interface effectively processes high-speed data, achieving zero latency and non-blocking, thus meeting the requirements for high-speed audio data transmission. In terms of audio data transmission, the UART interface achieves both reliability and high efficiency.
[0074] The audio data volume is relatively large, requiring the implementation of a data producer-consumer queue model. For the audio data received by the main control chip 132 via the second UART interface, a two-level buffer mechanism is used. The received raw data is stored in the first-level producer buffer queue. Consumers retrieve buffered data one by one, parse it according to the protocol, and store it in the second-level producer buffer queue. The second-level consumers then retrieve the buffered data and hand it over to the main control chip 132 for distribution and processing. The audio input data processed by the main control chip 132 uses a first-level buffer mechanism, storing the data in the output queue. After consumers retrieve the data, it is sent out via the second UART interface scheduled by the main control chip 132. The infrared data volume is relatively small, mainly involving the uploading of infrared received data and the downloading of infrared control data, which can be handled using an audio data processing model (i.e., a producer-consumer queue model).
[0075] Gateway controller 121 serves as the control core of gateway device 10, enabling functions such as voice control, device control, and infrared control. Voice control includes cloud server voice content playback, local voice playback on gateway device 10, and recording command uploading via interactive integration module 13.
[0076] The device control module is responsible for the smart devices (such as home appliances, etc.) downstream of the gateway device 10 that are directly connected to the gateway device 10 via wired communication circuit 122 or wireless communication circuit 123. The control commands for the smart devices include voice control commands transmitted through the human-machine voice interface via the interaction integration module 13. Of course, the voice control commands need to be uploaded by the gateway device 10 to the cloud server, and after the smart device control commands are successfully parsed, they are then sent to the corresponding specific smart devices.
[0077] Infrared control commands are instruction codes transmitted from gateway device 10 to interactive integration module 13 via the first UART interface. These infrared control command codes can be input via a human-machine voice interface, uploaded by gateway device 10, and parsed by the cloud server; alternatively, they can be infrared command codes carried by gateway device 10 itself and directly issued by the cloud server.
[0078] The gateway main circuit 12 is connected to the interaction integration module 13 and is used to transmit control signals (including voice signals and infrared signals) to the interaction integration module 13 to realize the control function of the gateway device 10. In some embodiments, the gateway device 10 communicates with smart devices (such as home appliances, home devices, etc.) through a wired communication circuit 122 or a wireless communication circuit 123, and the user controls the smart devices through the gateway device 10.
[0079] The gateway device provided in this embodiment integrates voice and infrared control functions, making the control methods of smart devices more extensive and convenient, more adaptable to diverse application scenarios, improving the convenience of smart device control, and enhancing the user experience.
[0080] Please see Figure 3 , Figure 3 The schematic diagram illustrates the circuit structure of the voice processing circuit in some embodiments of this utility model.
[0081] In some embodiments, the voice processing circuit 133 includes: a voice acquisition circuit 1331, a voice input processing circuit 1332, a voice output processing circuit 1333, and a speaker 1334. The voice input processing circuit 1332 is electrically connected to the voice acquisition circuit 1331 and the main control chip 132, respectively, and the voice output processing circuit 1333 is electrically connected to the main control chip 132 and the speaker 1334, respectively.
[0082] Specifically, the voice acquisition circuit 1331 acquires voice signals and transmits them to the voice input processing circuit 1332. The voice input processing circuit 1332 processes the voice signals to obtain the target voice and transmits it to the main control chip 132, which then transmits it to the voice output processing circuit 1333. The voice output processing circuit 1333 outputs the target voice to the speaker 1334. The speaker 1334 plays the target voice output by the voice output processing circuit 1333.
[0083] In some embodiments, the voice acquisition circuit 1331 may be any one or more of a dynamic microphone, a condenser microphone, and an array microphone, or may be any other suitable device or component.
[0084] In some embodiments, the voice input processing circuit 1332 is specifically used to perform a series of voice signal processing operations on the acquired voice signal, such as sensing, amplification, filtering, denoising, noise reduction, analog-to-digital conversion, cancellation, and encoding. The voice output processing circuit 1333 is specifically used to perform a series of voice data processing operations on the target voice data, such as decoding, digital-to-analog conversion, gain adjustment, and amplification.
[0085] The voice input processing circuit 1332 is used to analyze and convert the acquired voice signal data. After external voice is captured by the microphone, the voice is a series of continuous analog electrical signals. These analog signals need to be amplified, filtered, and denoised to convert them into digital electrical signals, resulting in machine-recognizable audio data. This digital audio data is then formatted into frames (e.g., PCM encoding). The main control chip 132 uses a second UART interface to send this audio data out for recognition and processing by the gateway device 10 or higher-level devices (e.g., cloud servers). It should be noted that the main control chip 132 can also recognize some specific audio input data, a technology known as offline voice recognition. Offline voice recognition requires professional voice training and can enhance the utilization value of voice processing, meeting the needs of more application scenarios.
[0086] The voice output processing circuit 1333 decodes audio format data (such as PCM encoded data), converting digital audio data into analog audio data. The analog audio data is then amplified and output to a speaker or loudspeaker for playback. To meet the needs of different application scenarios, the output audio data can also be tuned to make it more saturated and smoother.
[0087] In some embodiments, please refer to Figure 5 , Figure 5 The schematic diagram shows the specific circuit structure of some circuits in the speech processing circuit.
[0088] like Figure 5As shown, the voice output processing circuit 1333 includes a second capacitor C9, a third capacitor C10, a fourth capacitor C11, a fifth capacitor C12, a sixth capacitor C13, a first inductor L1, a first inductor L2, a voice input processing chip U14, a first resistor R7, a second resistor R8, a third resistor R9, a fourth resistor R10, a fifth resistor R11, a sixth resistor R12, and a first capacitor C14.

The second terminals of the second resistor R8, the third resistor R9, and the fourth resistor R10 are connected to the voice input processing chip U14, respectively. Test points TP13 and TP8 are respectively located at the second terminals of the third resistor R9 and the fourth resistor R10. The second terminal of the second resistor R8 is also connected to the first terminal of the first resistor R7, which is grounded. Test point TP9 is located at the second terminal of the second resistor R8 (i.e., the first terminal of the first resistor R7). The second terminals of the fifth resistor R11 and the sixth resistor R12 are both grounded. The first terminal of the first capacitor C14 is connected to the voice input processing chip U14, and the second terminal of the first capacitor C14 is grounded. The first terminals of the first inductor L1 and the first terminals of the first inductor L2 are connected to the voice input processing chip U14. The second terminal of the first inductor L1 is connected to the first terminals of the second capacitor C9, the fifth capacitor C12, and the sixth capacitor C13. The second terminal of the second capacitor C9 is connected to the second terminal of the first inductor L2, the first terminal of the third capacitor C10, and the negative terminal of the speaker 1334. The second terminals of the third capacitor C10, the fifth capacitor C12, and the sixth capacitor C13 are all grounded. The second terminal of the first inductor L2 is also connected to the first terminal of the third capacitor C10 and the first terminal of the fourth capacitor C11. The second terminal of the fourth capacitor C11 is grounded.
[0089] Please see Figure 4 , Figure 4 The diagram shows a schematic diagram of the speech processing circuit in some other embodiments of the present invention.
[0090] In some embodiments, the voice processing circuit 133 further includes a voice acquisition circuit 1335, which is electrically connected to the voice input processing circuit 1332 and the voice output processing circuit 1333, respectively.
[0091] Specifically, the voice echo acquisition circuit 1335 is used to acquire the target voice output by the voice output processing circuit 1333 and transmit the acquired target voice to the voice input processing circuit 1332 to perform echo cancellation operation.
[0092] In some embodiments, the voice back-acquisition circuit 1335 is specifically used to acquire the processed target voice data output by the voice output processing circuit 1333. The voice back-acquisition circuit 1335 transmits the target voice data to the voice input processing circuit 1332 for processing. Its main function is echo cancellation. The voice back-acquisition circuit 1335 is an essential processing circuit when voice input and voice output exist simultaneously. In addition, the processed playback audio data output by the voice output processing circuit 1333 is used as audio input data. After being back-acquired by the voice back-acquisition circuit 1335, the influence of the playback audio data on the voice input acquisition is eliminated. The voice back-acquisition circuit 1335 mainly employs echo cancellation, noise suppression, and automatic gain control techniques to achieve this.
[0093] Please see Figure 5 In some embodiments, the voice feedback circuit 1335 includes a seventh capacitor C1, an eighth capacitor C2, a ninth capacitor C3, a tenth capacitor C4, an eleventh capacitor C5, a twelfth capacitor C6, a thirteenth capacitor C7, a fourteenth capacitor C8, a seventh resistor R1, an eighth resistor R2, a ninth resistor R3, a tenth resistor R4, an eleventh resistor R5, and a twelfth resistor R6.

[0096] Specifically, the infrared receiving circuit 1341 is used to receive infrared signals sent by control devices (such as remote controls, smartphones, etc.), and the infrared driving circuit 1343 is used to be controlled by the main control chip 132, that is, to receive control signals or instructions from the main control chip 132 and drive the infrared transmitting circuit 1342 to transmit infrared signals.
[0097] In some embodiments, the infrared processing circuit 134 further includes: an infrared control circuit ( Figure 6-8 (Not shown in the image), the infrared control circuit is a unit module used to ensure the correct execution of infrared codes. It operates on a 38kHz carrier frequency, meeting the control requirements of home appliances and furniture. Infrared signal output is achieved by emitting infrared signals through infrared tubes. Depending on the specific business scenario, one or more infrared tubes can be designed to meet the need for comprehensive spatial control. Infrared signal input uses infrared receivers. Depending on the specific business scenario, one or more infrared receivers can be designed for comprehensive infrared data reception and processing, resulting in wider infrared signal reception coverage and meeting usage requirements.
[0098] The infrared processing circuit 134 is responsible for the output and input of infrared coded data. When infrared coded data is output, it is presented in a certain format (e.g., NEC) and then output to the infrared transmitter after passing through a carrier wave (e.g., PWM modulation). When infrared coded data is input, it receives external infrared code segments through an infrared receiver, which can directly convert them into infrared coded data (e.g., NEC). This input infrared coded data is used by the main control chip 132 for scheduling. The main control chip 132 sends the data to the gateway device 10 or transmits it to the cloud server for processing via the second UART interface.
[0099] It is worth noting that when outputting infrared encoded data, the infrared receiver can also receive the transmitted infrared encoded data. To reduce the impact of the output infrared encoded data, the data processed by the infrared input is compared with the data processed by the infrared output. If the comparison results are consistent, the input infrared encoded data is discarded. The principle for comparing the consistency of infrared input and output data is: within the allowable error range, the infrared encoded data can be identical. The allowable error range includes, for example, a rule of 500 microseconds for header information and 200 microseconds for data encoding information. Of course, those skilled in the art can adjust the allowable error range according to the sensitivity of the infrared transmitter and infrared receiver.
