摘要
文章介绍了一种四通道数字伺服控制器的系统设计和实现方案;针对研制任务中高通信波特率和多路控制的要求,设计了以XC164为主控制芯片,基于JS71175型485协议处理器的高速同步485总线通信的多通道伺服控制器,该控制器在提高了同步485通信速率的同时可以实现四路伺服机构的控制、伺服机构动作的锁定及解除锁定,具有体积小、功率大、集成度高特点;实验结果表明,在保证通信稳定的前提下,通信波特率可达2 Mbit/s,总功率可达1 600 W,满足任务要求。
A four -channel servo controller designing and realizing scheme for guided missiles is provided in this paper. According to high communication rate and multi -channel servo control requirements to the research task, the servo controller is designed base on 485 protocol processor of JS71175 and XC164 as main control chip, this controller improve synchronization 485 bus communication rate, meanwhile, real-ize for -channel servo mechanism control and lock or unlock servo mechanism action, have the characteristics of small volume, high power and high integration. The tests indicate that, under the premise of stable communication, communication rate up to 2Mbit/s, total power up to 1 600 w,and satisfies the task needs.
