摘要
基于Pushlet架构,设计了一个浏览器/服务器(B/S)模式的航天器在轨实时监测报警系统。该系统采用"发布/订阅"机制,客户端需要首先订阅在服务器端的某个主题,服务器端则接收订阅并进行注册,同时实时接收航天器在轨遥测数据并进行判读,通过持久HTTP连接向监测客户端实时推送异常判读结果,实现航天器在轨运行状态的实时监测和报警功能。测试结果表明,文章提出的系统具有实时性强、效率高和稳定性好的优点。
Based on Pushlet structure, a real-time monitoring and alarming system of browser/ server（B/S） mode for spacecraft in-orbit is proposed, which adopts the ＂publish/subscription＂ mechanism. Firstly, the client subscribes to a subject from the serve; secondly, the server ac- cepts and registers the subscription, and receives and interprets the real-time telemetry data from spacecraft. With the persistent HTTP link, the alarming information of telemetry parameters is published by the server and pushed to clients in time. Testing results show that the system has high real-time, efficiency and stability performances.
