基于口令识别的无线控制系统的设计

Wireless Control System Design Based on Speech Password Design

文章将口令识别与无线通信、机器人控制相结合,实现了基于口令识别的智能车无线控制系统。该系统包含接收和识别口令的主机,发送指令和接收指令的通信模块以及带有特定功能的智能车。主机识别口令后,以无线传送方式将指令发送给智能车,智能车按指令实现相应功能。主机和智能车都基于嵌入式系统。主机硬件电路由三星S3C6410处理器和外围电路组成,口令识别部分采用连续隐马尔科夫模型算法。实验表明,该系统有良好的稳定性和实用性。

A robot wireless control system,which combines speech password recognition,wireless communication and robot control,is proposed.The system has three blocks,the host,which receives and recognizes the speech password,the communication block,which is responsible for the command sending and receiving,and the robot with special functions.The host sends the command after receiving and recognizing the speech password.Then,robot acts according to the command.For the practical use,both the host and robot are embedded systems.The host hardware contains the kernel S3C6410 processor and its peripherals.Speech password recognition algorithm is based on CDHMM（continuous density hidden Markov model）.The experiments show that the system is stable and has good applicability.
