Chunlong Ma, Jianguo Li, Shuhan Yu · 2011
This essay aims at solving the problems such as low efficiency, high-error rates and inadequate real-time data acquisitions when using a portable soil electrical conductivity meter. Based on the theory of multi-sensor data fusion, a new method of measurement of soil electrical conductivity is given, with which soil electrical conductivity can be measured with the single sensor fusion algorithm of batch estimation combining with the method of adaptive weighted fusion. At the same time, a hardware system that achieves the algorithm is designed, and the soil electrical conductivity can be collected in real time by the hardware system. Thus, the problems can be solved by using the new measurement method. Innovation point of the essay is the method that the soil electrical conductivity can measured by the single sensor fusion algorithm of batch estimation combining with the method of adaptive weighted fusion.
