随着嵌入式技术的发展,如何让用户通过浏览器访问嵌入式系统中内置Web 服务器,以获取系统信息成为嵌入式系统设计的一个热点。web服务不但操作方便,而且可以实现对现场的远程监控, 甚至可以向监控设备发送指令,因此Web 服务在嵌入式系统中的实现具有重要的作用,由于嵌入式系统要求代码简练,执行效率高,性能稳定可靠等,因此选择合适的Web服务器显得尤为重要。本设计采用一款单任务的嵌入式Web 服务器Boa. 对Boa web服务器特点,如何搭建以及注意事项等进行了讨论, 在此基础上编写了后台cgi服务程序,对嵌入式设备中传感器采集到的数据通过网络和浏览器传递给用户,以使用户了解嵌入式设备的工作状态和采集到的信息。
With the development of embeded technology, how to permit the users to visit the built-in web server in the embeded system so as to obtain the system information has become a hot point of embeded system designing. With the features of convenient operation,remote control toward the work field and even sending orders to the monitoring equipment, the web server plays an important role in the realization of embeded system. Because the embeded system demands a simple code with a high executive efficiency and stable performance, users have to be cuatious enough to choose suitable web server. The design has adopted the embeded system Boa with simple task, and discussed the features of Boa web server, how to set up and some instructions that need to be noted,and meanwhile, on which base, compiled backgrounding cgi service procedure,transmitted the users the datas collected by the sensors in embeded equipments through the website and explorer. In this way, users can have a clear understanding of working conditions of embeded equipment and datas collected.
请大家说明的详细些,大小写,句式,时态哪里有错误都说明白点,谢谢大家了,最好有专业人员帮忙,兄弟急求!
