[0033] As Figure 1 The utility model discloses an offline voice recognition panel with infrared repeating function, including panel body, electronic circuit board set up in the panel body,

[0034] The electronic circuit board is integrated with microprocessor, voice recognition module and infrared emission module,

[0035] The voice recognition module and the infrared emission module all are connected with the microprocessor, and the voice recognition module is used to receive the voice instruction of user input and is converted into electric signal;The microprocessor is used to get the user instruction according to the electric signal sent by the voice recognition module, and sends the user instruction to the infrared emission module;The infrared emission module is used to emit the infrared control signal corresponding to the user instruction to target household appliance according to the user instruction.

[0036] Among them, the voice recognition module adopts advanced voice recognition algorithm, which can accurately identify the user's voice instruction. When the user issues a voice instruction, the microphone receives the sound signal and converts it into an electrical signal to transmit to the voice recognition module. The voice recognition module processes the electrical signal, extracts the voice features, and matches them with the pre-stored voice instruction template to identify the user's instruction intent.

[0037] Among them, the microprocessor receives the instruction intent transmitted by the voice recognition module, generates a corresponding control signal according to the instruction intent, and transmits the control signal to the infrared emission module. For example, if the user issues a "turn on the TV" voice instruction, the microprocessor identifies the instruction intent and generates a corresponding infrared control signal to control the infrared emission module to emit an opening signal to the TV.

[0038] It should be noted that an offline voice recognition panel with infrared forwarding function includes a panel body, a voice recognition module, a microprocessor, an infrared emission module, and a power module. The voice recognition module is used to receive the user's voice instruction and convert it into an electrical signal to transmit to the microprocessor. The microprocessor processes the received electrical signal, identifies the user's instruction intent, and controls the infrared emission module to emit corresponding infrared signals according to the instruction intent. The infrared emission module is used to emit infrared control signals to home appliances. The power module is used to provide power for the entire voice recognition panel. The panel body is provided with a microphone hole, an indicator light, and a button. The microphone hole is used to receive the user's voice instruction. The indicator light is used to display the working state of the voice recognition panel. The button is used to manually control some functions of the voice recognition panel.

[0039] Among them, the offline voice recognition panel with infrared forwarding function is usually used for smart home control, hotel management or other scenarios that require remote voice control. This panel combines voice recognition technology and infrared communication function, and can realize voice recognition, infrared forwarding, multi-functionality and intelligent connection function. Voice recognition: receive and analyze the user's voice instruction through the built-in microphone; Infrared forwarding: convert the recognized command into an infrared signal to control compatible devices (such as TV, air conditioner, etc.); Multi-functionality: in addition to voice control, physical buttons can also be used for operation; Intelligent connection: can be integrated with smart home system, supporting remote control and automatic scene setting.

[0040] Further, voice collection and conversion: when the user issues a voice instruction, the voice enters the voice recognition panel through the microphone hole on the panel body. The microphone converts the received sound signal into an electrical signal, which contains the acoustic feature information of the user's voice.

[0041] Voice recognition processing: The voice recognition module receives the electrical signals transmitted by the microphone and processes them using pre-stored voice recognition algorithms. First, the electrical signals are pre-processed through filtering, amplification, etc. to improve signal quality. Then, voice features such as voiceprint features and phoneme features are extracted. These features are matched with pre-stored instruction templates in the voice recognition module, which are voice feature patterns corresponding to various home appliance control operations (such as "turn on the TV" and "turn off the air conditioner"). Through feature matching algorithms, the voice recognition module identifies the user's instruction intent and sends the electrical signals containing instruction intent information to the microprocessor.

[0042] Instruction processing and infrared signal generation: After receiving the electrical signals from the voice recognition module, the microprocessor analyzes and processes the instruction intent information. The microprocessor has a control code mapping relationship for home appliances stored internally, and according to the identified instruction intent, it queries the corresponding infrared control code. Then, according to the requirements of the infrared communication protocol, it generates the corresponding infrared control signal. For example, if the instruction intent is to turn on the TV, the microprocessor will find and generate the corresponding infrared control signal for turning on the TV.

[0043] Infrared signal forwarding: The microprocessor sends the generated infrared control signal to the infrared emission module. The high-power infrared emission tube in the infrared emission module converts the electrical signal into an infrared light signal upon receiving the control signal and emits it towards the target home appliance. The emission angle and distance of the infrared emission module can be adjusted according to actual needs to ensure that the infrared signal can be accurately received by the target home appliance. After receiving the infrared signal, the home appliance performs the corresponding operation according to the control instructions contained in the infrared signal, such as turning on, turning off, adjusting volume or temperature, etc.

[0044] Status indication and manual control: During the entire working process, the indicator light on the panel body displays according to the working state of the voice recognition panel. For example, when the voice recognition panel is in standby state, the indicator light displays one color; when a voice instruction is received and being processed, it displays another color; when the infrared signal is successfully emitted, it displays a third color, etc. At the same time, the keys on the panel body can be used to manually control some functions of the voice recognition panel, such as power switch, reset, etc., providing a backup control means when the voice recognition function fails or the user wants to manually operate.

[0045] In this embodiment, the offline voice recognition panel does not need to be connected to the network, all voice instructions are stored inside the offline voice recognition panel, and the offline voice recognition panel supports Bluetooth mesh networking, which can control room lighting, curtains, etc. through voice recognition, and control room air conditioners, televisions, etc. through infrared forwarding.
