Yuan Hong-yin · Journal of Agricultural Mechanization Research · 2007
This paper designed timing system of seed-metering device laboratory table in order to use seed-metering device laboratory table to design seed-metering device of precision seeding machine. First introduces component of frequency conversion timing system of seed-metering device laboratory table. Then bases on the agreement of serial communication between a computer and a transducer, uses the Microsoft communication control of VC++ and VC++ 6.0 to design the control program of frequency conversion timing system of seed-metering device laboratory table, this control program can realize serial communication between a computer and a transducer. This system has many merits: convenient operating, many methods of timing, strong security and anti-jamming, etc. It can meet the need of adjusting speed real-time of seed-metering device laboratory table.
