Introduction Civil engineering, a professional engineering discipline, deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings [1-3].
It includes several sub-disciplines, e.g. environmental engineering, geotechnical engineering, Geophysics, Geodesy, Control engineering, structural engineering, biomechanics, nanotechnology, transportation engineering, earth science, atmospheric sciences, forensic engineering, municipal or urban engineering, water resources engineering, materials engineering, coastal engineering, surveying, and construction engineering [4-6].
In most countries, a Bachelor's degree in engineering represents the first step towards professional certification, and then the engineer must satisfy a range of requirements (including work experience and exam requirements) before being certified [8].
General civil engineers work closely with surveyors and specialized civil engineers so that they could fit and serve fixed projects within their given site, community and terrain by designing grading, drainage, pavement, water supply, sewer service, electric and communications supply, and land divisions.

Select measure points and experiment instruments Select five kinds of underlay in the test area: floor tile, grassland, concrete ground, permeable brick ground and water.
From the professional software Image Processor Pro II, we can read the bright temperature on the infrared image.
Then analyze the correlation between the two kinds of temperature of floor tile, grassland, concrete ground, permeable brick ground and water.
Fig. 13 The linear relationship between the two kinds of temperature of water Fig. 13 shows that the linear equation to the water is: Ta = 0.9965 Ts - 0.6392
The two kinds of temperature of water have a high-grade linear correlation.

Er Mao Qing tea production technology and green tea are basically the same, the main use of mechanical part for rolling process.In the individual farmers and small processing factory is mainly manual kneading.But in the subsequent 40 years, tea production technology is no big improvement, until now production enterprises has been in accordance with the traditional method of producing Pu'er tea, because tea production technology on the staff of production experience and professional level has a very high demand, and Pu'er tea fermentation process exist in health conditions difference, unstable quality, productivity is low problem, all these have a serious impact on the tea industry health, continuously, stable development.
Sensor instead of the thermometer, hygrometer and tea water oven method analysis, equipped with monitoring software, process parameter display timely and accurately, variable artificial measurement automatic measurement, labor saving; ( 2) the workshop environment artificial controllable.
Not affected by seasons, so that different batches of Pu'er tea quality tends to be stable; ( 3) control of water temperature control automation. ( 4) turning more accurate.
Tea Machinery Standardization Compared to other varieties of tea machinery, tea industry machinery research started late, Pu'er tea processing professional equipment lack of a unified technical standards.
