雷达状态监测系统数据传输技术的实现

Realization of data transmission for radar fault detection and diagnosis system

雷达状态监测与诊断系统必须具有对雷达进行数据采集与特征提取、实时监测、功能检查、故障显示及故障隔离等功能,而各功能的协同合作,监测点与主控机间的信息交换均需经数据传输这一重要环节,针对此提出一种在功能模块内部采用较为成熟便捷的USB方式,而在主机与各从机之间采用无线传输方式的解决方案,进一步解决了雷达监测与诊断系统中数据吞吐量大、冗余空间小、电路改造复杂等问题,并提高了系统的可靠性及可扩展性,增强了动态环境的适应性。

Radar fault detection and diagnosis system should have the whole function from data acquisition, character abstraction, real-time monitoring, functional check, data processing and transmission to fault display and analysis, fault location and isolation, etc. All the functions＇ cooperation and the communication between detection points and host depend on the data transmission. This paper presents a method, which employs USB at the inner parts of the whole system, while between the slaver and the host employs wireless communication. This method solves problems of big data handling capacity, little redundant space, and complex circuit reform; improves the reliability, expendability of the whole system and further more enhances the adaptability of dynamic environments.
