Summary: | Malaysia stands as a world's pertinent producer of palm oil, rubber and
cocoa. An increase in food imports coupled with limited agricultural workers have
driven the need for the development of integrated system for agriculture database to
manage the country's limited resources. The development of a database on power
and energy demand of various agricultural field operations is a prime concern for an
economical management of input resources for agricultural production.
A complete tractor instrumentation and data acquisition system was
developed and installed on a Massey Ferguson 3060 agricultural tractor for power
and energy demand mapping of the agricultural field operations in Malaysia. The
built-in instrumentation system is able to measure and display infonnation on engine
speed, PTO speed, forward speed, drive wheel slippage, acres worked, fuel
consumption per hour, fuel consumption per hectare, flied capacity, cost factor, fuel
consumed, fuel remaining, and distance. The developed data acquisition system is
able to measure and monitor horizontal pull at the tractor drawbar point, torques at
both tractor rear drive wheels, torque at the tractor PTO output, and the horizontal
and vertical forces on the implement at the 3-point hitch. Static calibration tests on all the designed transducers for the required measurements showed excellent
linearity (i.e., correlation coefficients closed to 0.99). The field trials demonstrated
that the datalogger and associated transducers were able to function successfully
without giving problems under the harsh field environments. The stored data in the
memory card of the datalogger from the field trials was able to be down loaded into
the hard disk of the host computer at the laboratory for post processing. |
