Around practicability,reliability and economy,the applicability of CAN bus in field irrigation was analyzed in this paper.Also,an autocontrol water saving irrigation system based CAN bus was constructed.By now,the design and development of main software and hardware have been completed.关键词: water...
pipe network of micro-irrigation project is summarized,too.Superficial suggestions for the application of computer tools in the design of irrigation pipe network optimization and its prospect are put forward.Some problems needing to be solved urgently for the future network optimization design are ...
Some limitations of GMs are their high computational demands, poor calibration and a complex design that precludes a thorough assessment of output uncertainties25,26. These drawbacks are amplified by uncertainties in crop types, growing seasons, agrarian practices, irrigated areas and local soil and ...
System hardware and software A prototype irrigation controller operated on AC 220 power was designed to autonomously control irrigation events based on the preset soil water status. The controller primarily consisted of a main board and three interface modules, i.e. input, output, and communication ...
Laboratory investigations were made in order to get a design for the Trummu Weir which would give maxi- mum coefficient of discharge, and the falls to be constructed on the canals have been exhaustively studied. At the River Research Station at Malikpur a model was made of the Rivers Chenab...
