|
摘要
针对校园中现有用电管理系统的存在的缺陷与弊端,提出了一种基于B/S架构的嵌入式远程用电管理系统的解决方案;系统以ARM-CORTEX-A8为主控板的核心处理器,Linux操作系统为应用程序的运行环境,同时在Linux系统中搭建了嵌入式BOA服务器;系统中使用html语言完成系统与用户的交互页面,并通过CGI技术实现了浏览器与嵌入式服务器的数据交互;为不改变原有建筑电力布线,系统终端采用zigbee无线网络实现远程的用电监控,从而实现远程用电管理系统;为使系统运行效率高,主进程中使用多线程技术完成系统中各任务,系统中使用数据共享内存的方式完成各进程间的数据通信,使用消息队列实现客户端对系统终端设备的控制,系统中通过sqlite3数据库完成所有历史数据的记载;通过系统实验测试,该系统可以正确响应用户需求以及满足校园内所设置的合理用电申请的远程用电管理要求,在安全、节约用电的同时有最大程度的方便了校园内非常规工作需求。
Aiming at the shortcomings and drawbacks of the existing power management system in campus,a solution of embedded remote electricity management system based on B/S architecture is proposed.The system uses ARM-CORTEX-A8 as the core processor of the main control board and the Linux operating system as the running environment of the application program.At the same time,the embedded BOA server is built in the Linux system.The system uses the html language to complete the system and user interaction pages,and through the CGI technology to achieve the browser and embedded server data interaction.In order not to change the original building power wiring,the system uses ZigBee wireless network terminal to achieve remote power monitoring,remote power management system is designer.In order to make the system run efficiently,the main process uses multithreading technology to complete the tasks in the system.The system uses data shared memory to complete the data communication between the processes.The message queue is used to realize the control of the system terminal equipment.Through the Sqlite3 database to complete all the historical data records.Through the system test,the system can correctly respond to user needs and to meet the campus set by the rational use of electricity applications for remote power management requirements in the safe and save electricity at the same time have the greatest degree of convenience to the campus of the unconventional work requirements.
