Technical Field

This patent belongs to the artificial intelligence field, designs an off-line intelligence voice switch circuit for the realization is through the load switch work within the speech control off-line 150W, does not receive the access restriction of internet, uses awakening word and operation vocabulary and is used for intelligent control instruction, and realizes artificial intelligence control's demand.

Background

The artificial intelligence field is a key field of development of the 21 st century, and particularly in the field of intelligent home furnishing, an intelligent sound box released by internet companies such as Temple of Temple, Baidu Xiaodu and the like is used as artificial intelligence control equipment of the intelligent home furnishing, so that a mode of voice convenient control is realized. However, the technology is based on internet access to realize information transfer, an algorithm is rooted on a cloud platform, and intelligent control can be realized only by transferring control information to terminal equipment after calculation through the cloud platform. However, in the application fields or areas where the network signal is poor, the network speed is slow, and no network exists, people cannot enjoy the convenience and the technological sense brought by artificial intelligence. Therefore, the off-line voice control switch circuit which can be accessed without depending on the internet is designed into a fixed switch circuit module to meet the basic experience and convenient use of people on artificial intelligence inside the algorithm root and the main control chip.

SUMMERY OF THE UTILITY MODEL

The intelligent voice control circuit is characterized in that an artificial intelligent circuit capable of carrying out voice intelligent control on a power switch can be carried out without internet access, so that the intelligent voice control requirements under the conditions of poor network signals, slow network speed and no network are met, the circuit uses YQ1210F2 or an equivalent platform and a voice processor chip above as a main control chip, an algorithm is rooted in the main control chip for operation, high-definition full-omnidirectional band sound pickup is carried out through a silicon microphone, voice information is obtained and then sent to the main control chip for operation management, an output instruction controls an optical relay to carry out switching operation, the maximum power of the optical relay is allowed to be 150W, the load requirement within 150W can be met, the YQ1210F2 chip has higher requirements on a working power supply, the interference is avoided, the safety isolation of the circuit is needed, the universal switching power supply is adopted to carry out AC110 39220V power supply change, the power supply is provided for the LDO 3.6V output power supply to the YQ 1210V, the power supply is provided for the LDO 3.6V, the power supply is provided for the EMC 6V switch, the LDO 1210V switch, the power supply, the voice output voltage is not exceed the voltage output of the voltage stabilizing power supply, the voice output of the voice output module, the voice output module is not exceeds the voice output voltage of the voice output module, the.

The main flow of voice control is shown in fig. 2, according to the principle mode, the system only needs a power supply to supply power to the voice circuit and the main control circuit, the voice circuit transmits signals to the main control circuit, the main control circuit performs operation to recognize voice signals when not connected to a network, a control instruction is given to control the switch circuit to perform an intelligent switch function of power switch work, network interconnection is not needed, and off-line voice intelligent control can be achieved without internet support such as a cloud platform.

According to the principle mode of fig. 1, the pickup module is implemented by selecting a high-definition full-frequency pickup MEMS microphone, the detailed structure of which is shown in fig. 3, the MEMS microphone is selected by using the latest ECM-like microphone, similar to the ZTS6618 microphone devices, and the circuit structure needs to consider a current limiting and filtering system.

The voice main control chip needs to use the LDO for voltage stabilization and provides stable 3.6V power supply, and the voice main control chip is characterized in that the 3.6V voltage stabilization power supply can ensure that the fluctuation influence and interference of voltage are reduced to the minimum so as not to influence the stability of system operation.

The voltage-stabilizing power supply, the main control circuit and the relay switch output detailed structure of the main control unit are shown in fig. 4, and the voice main control chip selects YQ1210F2 or equivalent platforms and above and writes an offline voice algorithm into the chip. After the system is powered on, the switch is automatically turned on to light, meanwhile, similar wake-up words such as a wake-up word 'light good' or 'brilliant good' are set for the voice main control module, and after a buzzing prompt is given, a power supply turning-off voice is spoken, the system automatically outputs an instruction to control the relay switch to turn off a circuit; after the system is awakened again, the voice of turning on the power supply is spoken, and then the system automatically outputs an instruction to control the relay switch to turn on the circuit. And the like to circularly work.
