中文摘要:

      针对某型航空发动机的性能测试需求，设计了基于CAN总线的上下位机实时测控系统，该系统综合应用了总线测试、虚拟仪器和实时操作系统等技术。针对CAN总线通信存在网络数据丢包问题，提出了基于缓冲器的数据包丢失补偿器的算法。经实践证明，该系统运行稳定可靠、实时性强、测控精度高，达到了预期的设计指标要求。

英文摘要:

      According to performance testing requirements of an aeroengine，a real-time measurement and control system of the host and lower computer is designed based on CAN.The system integrates many advanced technologies，such as bus test，virtual instruments and real-time operating system.In view of the data loss problem of CAN communication network，a data packet loss compensation algorithm is proposed based on buffer.The application results show that the system is stable and reliable，real-time，and has high precision in measurement and control，and achieves the desired design requirements.
