The Study on Methods of Reading Data with Digital Levels
LI Jin-hui · Microelectronics & Computer · 2005
Digital levels has been admitted by a great deal virtues because of its speedy measure, high precision and easy operation. It has been frequently used by many high precision domains and departments such as geodetic survey, large-scale engineering construction, industrial installation, crustal diastrophic monitor and science research. Digital water level is still in testing and researching stage in our country. In this paper, the design plan of how to read data automatically with digital levels is given and the system of measure is achieved. The design of the image of coded level ruler detection and means of read data are accomplished. It is proved reliable and reasonable by experimentation.
