基于BOA服务器的同步数据采集管理系统设计
|
摘要
针对目前风电机组管理中存在的监测数据获取和查看不便等问题,提出了一种基于B/S架构的嵌入式八通道同步数据采集配置管理系统。系统采用以ARM232为主控板的核心处理器,以Linux嵌入式系统为运行平台并搭建了Boa服务器;系统通过CGI接口技术实现了客户端与服务器端的数据交互,并采用Ajax进行异步数据传输、以JSON格式作为数据交互格式。同时在登录成功之后使用Session机制保存登录状态并实现超时退出功能,保证了系统准确、高效、安全的运行。经测试,该系统在运行时占用内存资源少,能够实现在页面整体无刷新的条件下对数据进行更新,运行稳定。
To solve the problems in the management of wind power units, such as the difficulty in obtaining and viewing monitoring data, an embedded eight-channel synchronous data acquisition and configuration management system is proposed based on B/S architecture. The system adopts ARM232 as the core processor of the main control board, and the Linux embedded system as the running platform to build the Boa server. The client and the server data interaction is achieved through the CGI interface technology, using the Ajax asynchronous data transmission, and the data of JSON as interactive format. At the same time, after successful login, the Session mechanism can save state and implement timeout exit function, and ensure the system operation at an accurate, efficient and safe state. Test shows the system occupies less memory resources at runtime, and can update the data in the condition of no whole-page refresh with stable operation.
