Abstract:
The present invention relates to a method for arranging automatic control of a mobile mining machine equipped with a bucket. The method comprises generating a general-purpose bucket emptying model that defines at least the path of the bucket of the mining machine for emptying it. The bucket emptying model is stored on a memory means. The bucket emptying model is fetched from the memory means in response to a need to define emptying the bucket for the route. At least data defining the path of the bucket in the fetched bucket emptying model are appended to the path data for use in the automatic control of the mining machine.
Abstract:
The present invention relates to defining a model used for automatic control of a mobile mining machine (1), wherein the model is defined of a production area environment and/or route of the mining machine (1) in the production area in a computer-aided manner with a model definition application. The definition of said model is arranged as a route definition process comprising several steps that are executed in a predefined order. This means defining (51) according to predefined step-wise definitions the actions allowed in the current step of the model definition process; displaying (52) to the user,information defined to be displayed for the current step according to predefined stepwise definitions;executing (53) automatically at least some of the functions related said model definition step according to the predefined stepwise definitions;and allowing (52) a user to select only actions allowed in said step and to move only according to the predefined order to an allowed model definition process step.

Abstract:
The present invention relates to a method of determining routes for arranging automatic control of a mobile mining machine. A return route is determined computer-aidedly for the mining machine on the basis of data concerning a route taught by driving by executing, by a data processing device configured for generating return routes, at least the following steps: determining a route identifier for the return route, determining as route points of the return route at least some of the route points of the drive route in a reverse order,wherein when determining route point data of the return route on the basis of the route point data of the drive route, deleting additional control data associated with one or more route points of the drive route,and storing the data determining the return route to be used for automatically controlling the mining machine.
Abstract:
A method for controlling loading material to a bucket (106) of a work machine (100) from a stack of material (204) is disclosed. The method comprises selecting a control profile to be used as a basic control profile comprising indications for positions of at least one of the bucket (106) and the boom (104) of the work machine (100) as a function of a distance travelled by the work machine with reference to a reference location; obtaining information of a distance travelled by the work machine (100) while loading material to the bucket (106); examining at least one condition regarding the work machine (100) during loading; and determining, on the basis of the examined condition, whether another position than indicated by the selected control profile is to be used for at least one of the bucket and the boom. If it is determined that another position than indicated by the selected control profile is to be used for at least one of the bucket and the boom, the method further comprises selecting said another position. There is also disclosed an apparatus, a computer program product, and a work machine.
Abstract:
The present invention relates to a method for defining an environment model and route for the purpose of arranging automatic control of a mobile mining machine.In the method, an initialisation point is defined for the definition of the environment model in a first area. Data for the environment model are defined on the basis of first location data, when driving the mining machine from the first area to a second area, the first location data being relative to said initialisation point. Data for route points of the route are defined by using at least some of the environment model data and second location data obtained when driving the mining machine between the second and first areas, the second location data being relative to said initialisation point. The data defining the route are stored for use in automatically controlling the mining machine.
Abstract:
According to an example aspect of the present invention, there is provided a method, comprising: detecting (310) a trigger for speed scale setting for a vehicle (20) autonomously operating at an underground worksite (1) and executing a drive order, defining (320) a speed scale for the vehicle on the basis of traffic flow of vehicles at the work site, transmitting (330) a speed scale control message to the vehicle during execution of the drive order, the speed scale control message comprising a speed scale information element indicative of the speed scale, and transmitting (350), in response to detecting (340) trigger for speed scale cancellation on the basis of updated traffic flow information, a speed scale cancel control message to the vehicle executing the drive order, wherein the speed scale cancel control message indicates cancellation of the speed scale.
Abstract:
According to an example aspect of the present invention, there is provided a method for a zone passage control system for an underground worksite comprising a plurality of operation zones for autonomously operating mobile vehicle operations, comprising: associating a first passage control unit with a first zone and a second zone, detecting state parameter information of the first zone and the second zone, merging the first zone and the second zone into a fusion zone on the basis of the state parameter information of the first zone and the second zone, and adapting the zone passage control system to allow a first autonomously operating mobile vehicle to pass the first passage control unit in the fusion zone without interrupting operation of a second autonomously operating mobile vehicle in the first zone and/or the second zone.
Abstract:
A system (13) for zone passage control for a zone (OZ23, OZ4, OZ5, OZ6, OZ9) of an autonomously operating mobile object (9) comprises at least a set of detection units (14a, 14b, 14c, 14d, 14e, 14f) to detect at least one mobile object (9, 10) entering and/or exiting the zone, a set of identification units (15a, 15b, 15c, 15d, 15e, 5f) to identify the mobile object (9, 10) entering and/or exiting the zone, and a central controller (19) being arranged in operational connection with the set of the detection units and with the set of the identification units. An admissibility level (AL) for a mobile object (9, 10) to enter the zone is determined and a control signal (CS) to stop at least one autonomously operating mobile object (9) existing in the zone is provided in response to the determined admissibility level being negative for the mobile object (9, 0) entered the zone.
