METHOD AND APPARATUS FOR CONTROLLING THE LINEAR MOVEMENT OF AN AERIAL WORK PLATFORM

WIPO Patent Application WO/2012/153958

A3

The present invention relates to a method and apparatus for controlling the linear movement of an aerial work platform, which enable easy operation in terms of ergonomics. More particularly, the present invention relates to a method and apparatus, which involve receiving, from an operator, an operating command for a rectangular coordinate system that is familiar to humans, converting the inputted operating command into a control command for a spherical coordinate system, and outputting the converted command to an apparatus for driving an aerial work platform so as to enable the operation of the aerial work platform. The control method according to the present invention is a method for controlling an aerial work platform that includes a boom, one end of which is connected to the position corresponding to the zero point of a three-dimensional coordinate system, and the length, derricking angle, and turning angle of which are adjustable; and a platform, which is connected to the other end of the boom and which is rotatable in the left and right directions, wherein coordinates of the target point of the platform are obtained and the aerial work platform is controlled on the basis of the information obtained by converting the coordinates of the target point into spherical coordinates in a rectangular coordinate system in which the x-axis and y-axis rotate, according to the rotational angle of the platform, about a z-axis serving as a rotational axis.
