Abstract:
The laser leveling technology has a series of important advantages
over the classic technology: high precision, substantial diminution of the
tracing effort, reduced on site implementation effort of the leveling project,
reduced number of crosses which has significant implications in the time ,
fuel and labor effort consumption and the soil subsidence grade. In
principle, control and actuation of the operating parts are achieved trough
the following components: the laser equipment (emitter and receiver sensor),
electronic tracing and actuation module and
the proportional electro
hydraulic system.
The results of our research consist in: setting a configuration for the
laser control system on two groups of components: basic, which is valid for
all hydraulic drive leveling machines and specific, which differs according to
the mobility of the operating parts (scoops and blades); making an option for
a leveling machine, in order to mount on this one the specific laser control
system; making the hydraulic drive system of this machine compatible with
the specific laser control system.
Research activities will be carried on as follows: mounting the laser
control equipment on a tractor grader; laying out the project for leveling the
agricultural land which on tests will be carried; indoor tests on the laser
equipment, under conditions of simulating the real behaviour on a machine;
outdoor tests, under real operating conditions, on the leveling machine
equipped with the laser system; quality analysis on the leveling work
performed and functionality of the system.
Research will not be directed towards designing and developing laser
components, electronic or hydraulic ones, and specific to all leveling
machines, which already have their top providers on a world level. It will
aim to integrate these components within a modular system designed for use
in agriculture and meant to raise efficiency of water consumption on
agricultural lands.
