A production system for a forestry application comprising a server and a wireless production network, configured to be connected to forest machines and vehicles, at least one forestry harvester vehicle and one forwarder vehicle, the vehicles having a wireless data connection to the production system server and network, having a positioning system, identify the type of processed logs, measure the amount of processed logs, measure the lengths of processed logs, measure the quality of the processes logs, visually record the vehicle surroundings, process the recorded images to identify objects, store them, and send them via the production network, the vehicles having a display so that the vehicle operator may compare images with different time stamps, the system adapted to visualize changes between the images based on the identified objects and time stamps, so that the vehicle operator may identify tracks, objects, logs, log piles during visually impaired conditions.

Production system and method for forestry application

The disclosure relates to a method for controlling the crane of a working machine by using boom tip control, in which method the crane comprises at least two booms connected to the working machine and each other in an articulated manner, which booms are moved in relation to the working machine and to each other by means of actuators controlled by a control system of the working machine, and in which method the direction and speed of motion of the head of the crane, controlled by the driver applying controls in the working machine, is implemented by applying speeds of the different booms of the crane. In the method according to the disclosure the speeds of different booms of the crane are determined automatically on the basis of at least one of the following factors: positions of the different booms of the crane in relation to the extreme position of their range of motion; the maximum speed of the head of the crane achieved by the crane; maximum force achieved by the crane; location of the head of the crane in relation to the working machine; location of surrounding obstacles in relation to the crane. The disclosure also relates to a system for controlling the head of the crane of a working machine by boom tip control.

Method and system for controlling the crane of a working machine by using boom tip control

A system and a method for controlling a tool pivotably mounted to an articulated boom connected to a work machine having a control unit. The solution: 1) determining the direction a predetermined point of the boom or the tool is moving to, i.e. the moving direction, and 2) controlling orientation of the tool as a function of one or several predetermined dependencies, the predetermined dependencies defining at least the orientation of the tool in relation to the moving direction. According to an example the work machine is a forest machine.
