This paper presents the new structure integrated data acquisition system and intelligent control system on agricultural facilities, in order to promote the information-based and intelligent level of comprehensive agricultural zone and to improve the production efficiency and effectiveness. The system included of agricultural intelligent frequency conversion irrigation function, and automatic control function of greenhouse combined with the sensor nodes, wireless transmission network and sensor configuration, data collection system. The system developed in greenhouse practical application has received the good effect in Tianjin. Due to realized the real-time data automatic acquisition of greenhouse environment parameters and biological information, the farmer achieved good economic and ecological benefits, and the great significance to the development of modern agricultural information-based and intelligent. Keywords-the Internet of Things; facility agriculture; intelligent control; system design and implementationI.

Abstract-In the basis of empirical research, the viewpoint that is about the old theory of teaching contents and weak experiment teaching in China's universities is proposed. This leads to the phenomenon that the standard of information graduates is not suited to the development of software industry. The data of teaching satisfaction about the software engineering comes from questionnaires of 100 software professionals who have graduated from colleges for 3～5 years in Tianjin. The conclusion that software testing and experimental teaching should be strengthened in the proportion of teaching curriculum is got through the principal components analysis and quaternary graph. It points out a direction for the development of "Software engineering" curriculum.
