In this paper, a personal local area network in which automobile users can voice control the automobile is built inside the automobile. By combining voice recognition technology with wireless technology, an intelligent car system with voice recognition function is designed by using single chip microcomputer SPCE061A and personal wireless LAN intelligent network SOC chip CC2530. The system overcomes the defects that the traditional single chip microcomputer chip is in the car body, far away from the sound source and high noise. The single chip microcomputer and the coordinator in the intelligent network form the remote controller, and the nodes of the intelligent network form the transmitting equipment. The voice information is recognized in SPCE061A, translated into control commands, and sent to the terminal equipment through the intelligent network, Realize the control of trolley direction and speed.
