| In this thesis, key technology of monitoring and control systems based on embedded Internet technology was deeply researched. Based on embedded Internet technology, a remote monitoring and control system with basic functions was developed, which was composed of an embedded gateway and several data acquisition cards. Through the embedded gateway, 8/16 bit equipment could be accessed by Internet.Based on ARM7TDMI core, S3C4510B integrated many peripheral devices. The hardware platform of the embedded gateway was developed by taking S3C4510B as the core. Key technology of embedded gateways was introduced in detail.The characteristics and key technology of uClinux was deeply researched and analyzed. In the light of particularity of the hardware platform of the embedded gateway, μClinux was embedded into the hardware platform. On the basis of μClinux, the basic functions of embedded gateway were realized.Embedded Internet technology will change the architecture of monitoring and control systems, enhance the system's expansibility and reduce the cost. Taking the designed remote monitoring and control system as an example, this paper presented the design thinking, method and key technologies when using embedded Internet technology. Finally, the test result showed the validity of the research.
