Method and apparatus for the automatic guidance of the machines, in particular of a machine for laying elements of the drainage

摘要

Process and apparatus for the automatic guidance of an earthmoving machine, according to arrangements planimetric and of the profiles altimetric determines. / p & & p & according to the present process is recorded at prior, in the form, 1984, and on a movable magnetic support s, the set of clinical planimetric and altimetric of the work for carrying out, with reference to the points of repere and has a plane of reference. It is then placed in the field of the fixed beacons 9 intended materialize on the spot the points of repere chosen so that the laser beam rotating, to define the plane of reference desired. As regards the earthmoving machine 11, a guide, it comprises a module for controlling a microprocessor able to read the instructions recorded on the magnetic support used, and therefore two guiding modules: one for the guidance planimetric of the vehicle, and the other for the guidance altimeter of the tool 13 of the excavation of this vehicle. However, these two control modules are able to act respectively on the control of the direction of the device 11 and on the system for controlling the position in height of the tool 13, and this, with reference to the fixed beacons 9 of repere and to the plane defined by the laser beam. / p & & p & this process and this equipment can be used for guiding an earthmoving machine, such as a machine for ensuring the positioning of elements of the drainage in the ground of a terrain.
