- 摘要:
- 为了解决以往液体火箭发动机试车测控系统数据总线带宽及可靠性低,实时性、系统维护性及拓展性差等问题,首次建立了基于工业控制总线CAN总线和CANopen应用层运动控制子协议的综合测控系统,并且针对以往基于RS—422串口数据总线的“点对点”结构数据通讯速率低、可靠性低、维护性差的缺点,构建“一主多从”式节点可拓展的组网式总线拓扑结构。经过X型液氧煤油火箭发动机试车验证,证明该系统已实现高可靠、长距离、高实时的数据通讯和高精度伺服控制,实现了完整的CANopen运动控制协议软件驱动层设计。利用该发动机综合测控系统的研制方法与思路,可在未来的发动机测控系统中实现多节点、智能化伺服控制,为新一代液体火箭发动机智能化控制器和测控系统的研制提供新思路。
- Abstract:
- In order to solve the problems of past liquid rocket engine trial system such as low bandwidth,low reliability and real-time performance,poor system maintainability and expansibility,a integrated measurement and control system was established,which is based on industrial control bus CAN bus and CANopen motion control sub-protocol in application layer the first time,and contraposing the past RS422 serial data bus's "peer-to-peer" structure disadvantages such as low data communication rate,low reliability,poor maintenance.A node scalable "one master many slave" mode data bus topology structure was established.This integrated control system was verified by X type liquid oxygen kerosene rocket engine trial to achieve high reliability,long distance,high real-time performance data communication and high precision servo control,and a complete CANopen motion control sub-protocol driver layer software was designed.Using this liquid rocket engine trial's integrated measurement and control system can achieve multi-mode and intelligent servo control in future engine measurement and control system,which provides a neoteric method for a new generation of liquid rocket engine intelligent contoller and control system research.
