摘要
针对原有遥测数据传输模式的缺陷,构建了新型统一的数据模型。系统采用数据库技术来存储遥测数据处理全过程所需配置信息,从遥测数据库中读取系统所需信息,根据遥测帧格式信息,对接收到的遥测原始数据进行验证并组帧;随后挑点解算需要处理的遥测参数。依据该数据库模型来重新设计遥测数据传输系统的软件架构,通过优化系统架构、减少了软件维护工作量,使软件系统具有较强的通用性和扩展性。系统在新型火箭飞行测控任务中得到了很好的应用。
According to the defects in the original telemetry data transmission mode, a new unified data model is constructed. The system utilizes the database technology to store the required configuration information of the whole telemetry data processing, reads sys- tem information needed from the telemetry database, verifies and frames the received original telemetry data, then picks out and calcu- lates telemetry parameters that need processing. The software frame of the telemetry data transmission system is redesigned according to the database model. The software maintenance work is reduced by optimizing the system framework, which makes the software system have strong universality and scalability. The system has been applied successfully in the new rocket flight control tasks.
