Introduction In the course of using the civil engineering structure and bridge structure, due to fatigue, damage, sudden disaster, these structures will be damaged endanger human lives.
In the late 1980s, researchers of civil engineering in Japan started to develop smart materials that can sense and control.
In the United States in 1993, smart materials on the civil engineering and plants of smart structure were opened.
It is very significant for smart concrete to monitor strain of major civil engineering infrastructure, assess damage non-destructive, repair timely and reduce the impact of typhoons and earthquakes and so on.

For this, this paper takes agricultural engineering information system as the object, analyzes the agricultural engineering information system by SWOT analysis method.
SWOT Analysis of Agriculture Engineering Information System Strengths.
At present, in order to improve our country informatization system, the country has full implementation in information resources development engineering, information infrastructure, information engineering, electronic commerce engineering, information product engineering.
Scendly, the engineering of agricultural information compartmentalization is the internal threats of agriculture engineering information system construction.
The government should strive to create a suitable environmental, in which information service subject can form and develop, such as speeding up the agricultural information engineering system reform and innovation, to encourage and support various non-profit specializing in agriculture and rural information consulting services and intermediary organizations and civil society development, to change the single pattern which government as the main body of agricultural information engineering system, finally the development of agricultural information service industrialization and agricultural information service socialization can be realize.
