双通道嵌入式数字伺服控制板设计研究

Design Study of the Double Channel Embedded Digital Servo Control Board

将双通道的伺服控制功能集成在一块计算机通用接口板上,同时将所有参数设计为数字调节模式,构成可拼组式数字伺服控制系统。以微型计算机为伺服控制系统主控机,每块板采用一片80C196实现两通道的数字伺服控制功能,同时具有各种故障检测功能,提高伺服控制系统的硬件利用率,现场拼组、使用灵活方便。

On the circuit board, which has a gen-eral-purpose interface bus, two servo-control channels are integrated, and the digital mode is designed for adjust-ment of all the parameters. Thus, using this kind of board, the difference digital servo-control systems can be formed.A microcomputer is used to form a control system. The board uses a piece of 80C196 to actualize the digital servo-control function of double channels, which can provide the functions of detecting various malfunctions. The board improves the hardware efficiency of the servo-control system, and can be formed in the field. The digital servo-control system is agile, credible and con-venient.
