A data collection device for work machines collects data from a component mounted on a work machine. The data collection device includes a collection unit that collects the data from the component via a vehicle-mounted network, and a conversion unit that generates a unified data object by converting the collected data into a predetermined format, and a data transmission unit that transmits the unified data object to the outside.

There are provided a position calculator that determines a position of working equipment included in a work machine, a display that displays a route image corresponding to a route through which the working equipment moves, and a display processor that causes, on the basis of a position of the route and a position of the working equipment determined by the position calculator, the display to display the route image corresponding to a portion of the route that is shielded by the working equipment with a predetermined position serving as a viewpoint in a form different from the route image corresponding to a portion of the route that is not shielded by the working equipment.

The application relates to a method for an automatic movement of a working device that comprises a control and at least two components movable independently of one another by means of a respective one actuator controllable by the control. The control has a learning mode and a work through mode, wherein the working device is automatically traveled from a first position into a second position by a corresponding control of the actuators in the work through mode. In the learning mode, the control detects data relating to the individual movements of the components during a movement of the working device and stores them, with the control of the actuators taking place during the automatic movement on the basis of these data in the work through mode. A parameter of the automatic movement is settable by the operator. The application further relates to a working device carrying out of the method application.

An excavator attachment is attached to a rotating platform of an excavator. A display unit visually displays a predicted stability indicating stability of the posture of the excavator after the excavator is manipulated.

The invention relates to a work machine and a method for monitoring a control system at a work machine (1a). According to the method, in-parameters (32, 34, 36, 38) are obtained in the form of signals from the control system, wherein the control system generates actual values on one or more out-parameters (42, 44) in the form of signals based on said in-parameters. A characteristic of the invention is that a digital flow of data, comprising both said in-parameters and out-parameters via a control bus (5a, 5b), is addressed to a RAM buffer memory (3b,3c), which is included in a personal computer (3a) onboard the work machine, which buffer memory in FIFO mode writes a data file (id:1.1-id1:n) of a predetermined size, which is saved in a non-volatile data support memory (3d).

The invention relates to civil engineering underground equipment comprising at least one work element for ground work, at least two actuation units, at least one measuring device for determining at least one current actuation parameter for each actuation unit, and a controller which is designed for controlling the actuation units, wherein the controller is connected to the measuring devices and, in order to prevent a tipping of the civil engineering underground equipment, is designed to limit a further actuation of the actuation unit or to display to an operator that the limit actuation parameter has been reached and/or the limit actuation parameter, on the basis of previously calculated limit actuation parameters for the actuation units which define exactly one permissible operating range, when a limit actuation parameter of at least one actuation unit is reached. It is intended for at least two different individual operating ranges to be stored in the controller, wherein each individual operating range comprises a different set of limit actuation parameters for the actuation units, and for the controller to be able to determine a combined permissible operating range.

A controller outputs a first velocity (first limiting velocity) as a limiting velocity for a boom cylinder when a boom lowering operation amount is smaller than a first operation amount, and outputs a second velocity when the boom lowering operation amount is equal to or larger than the first operation amount. The first velocity is set to decrease according to a decrease in a target surface distance. The second velocity is defined by a weighted average of the first velocity and a third velocity (second limiting velocity) set to change according to one of the target surface distance and the boom lowering operation amount of the operation device, and is set such that an increase in the boom lowering operation amount reduces a weight for the first velocity while increasing a weight for the third velocity.

A control unit of a temperature measurement system for a road construction machine; the control unit having access to a database, a plurality of specification data sets stored on the database, each of the plurality of specification data sets being assigned to a local region and including a temperature measurement specification and/or a temperature measurement report specification; including a data set selector and a data analyzer. The data set selector is configured to select a respective specification data set from the plurality based on position information for the road construction machine, the position information pointing to the respective local region. The data analyzer is connected to a temperature sensor and configured to analyze raw data received from the temperature sensor taking into account the selected temperature measurement specification and/or to output a local specific temperature report based on analyzed raw data taking into account the selected temperature measurement report specification.

The present invention relates to a system for determining the mass of a payload moved by a working device of a machine, comprising: a lifting-gear element that is movable along a path and is designed to move the working device; a sensor system that is designed to provide a plurality of machine-status signals which indicate a status of the machine; a force sensor system that is designed to provide a lifting-force signal that indicates a force on the lifting-gear element; and a control device that is designed: to use system parameters for load determination that originate from pre-configured CAD data, preferably CAD data that has been pre-configured at the factory, and/or from continuous calibration of system parameters; to carry out calibration using the pre-configured parameters as initialisation if unsatisfactory results are achieved; to carry out the calibration in an unloaded state, i.e. when the working device is empty, with automatically predefined stimulation trajectories being used for the machine or instructions being provided to the operator for stimulating the parameters; to log the system statuses using the sensor and to carry out a system identification of this information; and to determine a mass of the payload on the basis of identified and/or pre-configured system parameters and system statuses, preferably on the basis of a position, a speed, an acceleration of the lifting-gear element and/or a force or torque on the lifting-gear element.

The invention is based on controlling operations of an earthmoving machine controllable by the operator by using only one to four controllers and at least one displaying means for displaying controls selectable and controllable by the one to four controllers. The selections and controls of the operations for controlling the earthmoving machine may be transmitted to the control unit both by wire and wirelessly. Thus, the one to four controllers are operable both attached and detached. Further, the control system is arranged to determine the location of the one to four controllers with respect to the earthmoving machine.
