摘要：

动中通在保持实时稳定对星、跟踪过程中，针对天线控制器ACU难以满足算法开发、故障诊断、便捷调试、可视化界面等问题，设计一款动中通控制系统软件。软件以LabWindows/CVI为平台，针对软件高速采集数据要求，提出响应的控制策略，通过多线程技术与数据保护机制，使用线程池和Timer控件定时判断、开启数据采集线程和绘图线程，提升软件数据采集速率；使用线程安全队列技术保护共享数据；利用工具包SQL Toolkit开发卫星数据库等。测试结果表明：软件能够可靠准确地完成通信、数据处理任务，绘图功能流畅快速，为系统工作的监控、调试以及故障诊断提供充分的技术支撑。

Abstract: When keeping real-time aiming and tracking of SOTM, a kind of SOTM control system software was designed according to the problems that it is difficult for antenna controller ACU to meet the requirements of algorithm development, fault diagnosis, convenience commissioning and visual interface. The software was designed based on LabWindows/CVI platform, and response control strategies were proposed according to the high-speed data acquisition requirements. By utilizing multithreading technology and data protection mechanism, thread pool and Timer controls were used to judge and start data acquisition thread and drawing thread on time to raise data acquisition velocity of the software. Besides, thread-safe queue technology was used to protect shared data and SQL Toolkit was used to develop satellite database. The test results show that the software can reliably and accurately fulfill communication and data processing tasks, and the drawing function is smooth and fast, which provides sufficient technical support for monitoring, commissioning and fault diagnosis of the system.
