Taking Mianyuan River Basin as case study, the co-seismic landslides were detected automatically using decision-making tree method on ALOS satellite imagery post the 2008 Wenchuan earthquake. These landslides cover an area of 48.5km2. The distribution of landslides was dominated by the seismogenic fault. Furthermore, the lithology determined the type of landslides. Shallow disrupted falls were mainly...
A microcontroller based on alarm device is developed for detecting a combine working station preventing crop conveying pipeline blocked by excessive feed-in quantity so as to avoid driving belt or driving wheel being damaged. An Atmel 89C2051 single chip microcontroller is employed as the core of the device to make the system simple in structure and small in size. Using Hall effect tachometric transducers...
Agriculture-Greenhouses temperature and humidity monitoring system is introduced in order to reduce labor, increase to production efficiency, achieve to precise control of temperature and humidity in this paper. It depends on PID control technology, each node uses Siemens S7-224 as a master machine, and temperature sensor LM35 to detect the temperature of soil and air, and humidity sensor SHT15 to...
