摘　　要：为实现嵌入式Internet环境下的非标设备的网络化和智能化管理,提出并研究了Internet非标设备接入服务器Webit2 0的体系结构及实现技术·Webit2 0是在嵌入式实时操作系统的基础上,对传统的TCP/IP协议栈进行了约简,通过约简后的thinTCP/IP实现了嵌入式Web服务器的功能,使Internet非标设备具备了Web功能·同时,在应用中增加了SNMP和SMTP协议,实现了对设备的网络化管理·使管理者可以不受时空限制,通过Internet利用Web浏览器对设备的'行为'进行远程监控、实时管理、智能报警及下载驱动程序等操作,为实现工业设备的信息化管理和智能家居提供了可能性和技术上的支持·The architecture of non-PC devices' Internet access server-Webit 2.0 is proposed and implemented to realize the networked and intellectualized management of non-PC devices in the embedded Internet environment. Webit 2.0 simplifies the conventional TCP/IP protocol stack based on embedded real-time operating system, and realizes the function of embedded Web server in non-PC devices. Furthermore, SNMP and SMTP protocols are added to Webit 2.0, thus implementing the network management in non-PC devices so as to enable remote users to access transparently the devices over Internet with Web browser and accomplish such operations as device monitoring, real-time management, emergency alarm and download the device driver. Webit 2.0 can therefore provide the possibility and technical assistance for the implementation of information management of industrial equipment and intelligent home systems.
