The present invention provides a control system for controlling a loading machine comprising a work machine with a bucket, the control system comprising a controller. The controller calculates a traction force of the loading machine during excavation work in which the bucket is used to excavate an object of excavation. The controller acquires a bucket angle indicating the angle of the bucket relative to the horizontal plane during the excavation work. The controller calculates the weight of an excavated matter, that is, the object of excavation held in the bucket, on the basis of the traction force, the bucket angle, and bucket data indicating the shape and dimensions of the bucket.

INFORMATION ACQUISITION SYSTEM AND INFORMATION ACQUISITION METHOD
In the present invention, information relating to a work machine is acquired more accurately, with simple work. The information acquisition system comprises: a hydraulic excavator (100); a target unit (40); a position measurement unit (50); and an information acquisition unit (60). The hydraulic excavator (100) includes a swivel body (3) and a work machine (2) which is movable relative to the swivel body (3). The target unit (40) is attached to the work machine (2). The position measurement unit (50) discretely measures, a plurality of times, the position of the target unit (40), which moves as the work machine (2) moves relative to the swivel body (3). The information acquisition unit (60) acquires information relating to the hydraulic excavator (100) from the measurement results for the position of the target unit (40).
This monitoring system for an operating machine includes a measurement data acquisition unit for acquiring measurement data of the ground with which a rotation member of the operating machine is in contact and on which the operating machine runs by rotation of the rotation member, a boulder stone determination unit for determining the presence or absence of a boulder stone on the ground in the measurement data, and a warning control unit for allowing an output device to output a warning on the basis of the presence or absence of a boulder stone on the ground in the direction in which the rotation member moves.
This monitoring system for a work machine comprises: a first imaging device provided on the work machine, which captures an image of an implement of the work machine, and which has a first angle of view; a second imaging device provided on the work machine, which captures an image of a ground surface on which the work machine travels, and which has a second angle of view wider than the first angle of view; a damage determination unit that determines whether the implement has damage on the basis of the image data captured by the first imaging device; and a boulder determination unit that determines whether there is a boulder on the ground surface on the basis of the image data captured by the second imaging device.
A hydraulic shovel (1) comprises a shovel main body (2), a detection unit (4), and a controller (3). The shovel main body (2) has a traveling body (11) and a pivoting body (12). The pivoting body (12) has a work implement (15) and can pivot in relation to the traveling body (11). The detection unit (4) detects the position of the work implement (15). When the pivoting body (12) has been caused to pivot and it is determined that the work implement (15) will interfere with an imaginary wall (W) set at a predetermined position from the shovel main body (2) on the basis of the position of the work implement (15), the controller (3) changes the orientation of the work implement (15) so as to not interfere with the imaginary wall (W).
A controller (110) of a crawler (1) performs control for reducing the amount of hydraulic oil supplied from a hydraulic pressure supply unit (100) to a swivel motor (80) when driving an angle cylinder (8) and a lift cylinder (9) in a situation in which the swivel motor (80) is being rotated.
This processing machine comprises: a tool for machining a workpiece; and a depth camera which is installed such that the workpiece lies within an image capturing range thereof, and which captures an image of the depth of a subject. A position measuring unit calculates a three-dimensional position of a surface of the workpiece on the basis of the depth image captured by the depth camera. A positioning unit calculates a three-dimensional position of a target shape of the workpiece when the workpiece and the target shape are superimposed, on the basis of three-dimensional data representing the target shape and the three-dimensional position of the workpiece. A depth-of-cut determining unit determines a depth of cut at each of a plurality of points on the surface of the workpiece on the basis of a difference, in a sight line direction, between the three-dimensional position of the surface of the workpiece when the workpiece is viewed from a predetermined viewpoint, and the three-dimensional position of the surface of the target shape. The tool control unit causes the tool to move on the basis of the determined depth of cut.
