Abstract

The present invention provides an intelligent sound control obstacle avoidance dolly based on a single-chip microcomputer and a control method thereof. The intelligent sound control obstacle avoidancedolly is formed by a dolly main controller and a sound control remote control. The sound control remote control receives an instruction emitted by an operator, performs corresponding identification,displays a speech identification result through a LCD display circuit, and sends the speech identification result to the dolly main controller through a wireless receiving and dispatching module. Thedolly main controller receives an instruction sent by the sound control remote control through the wireless receiving and dispatching module, corresponding operation is executed after determination, corresponding prompting is performed through a speech play module, a related instruction is sent to the sound control remote control through the wireless receiving and dispatching module, and the soundcontrol remote control controls a LCD display circuit to perform display of corresponding prompting information. The problems are solved that a traditional method is not high in control precision, easy to generate false action and misoperation, the intelligence degree is higher, interaction with the operator is achieved through speech and character display modes to allow the operator to enjoy happiness brought by the music when the operator performs cycle racing.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and relates to an intelligent sound-activated obstacle avoidance car based on a single-chip microcomputer. Application of children's educational smart toys. Background technique [0002] Speech recognition technology is a technology that enables machines to convert speech into corresponding text or commands through recognition and understanding. With the rapid development of electronics and information technology, speech recognition is widely used in various fields. Voice control system is one of the common application areas, such as industrial control, voice dialing system, smart home appliances, voice-activated smart toys, etc. [0003] In the traditional voice control system, the voice signal is collected by the sound sensor, and then the sound is encoded by AD conversion and a dedicated voice chip, and the sound model is stored in the externally expanded flash chip. When the ex...
