Abstract
A method of determining a payload mass, the method comprising receiving rope data indicative of the rope force from the rope force sensor, receive position data indicative of the current shovel position from the one or more position sensors, determine a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and provide the payload mass to a display device associated with the mining shovel.
Claims30
A mining shovel comprising:
- a base;
- a handle rotationally coupled to the base;
- a bucket coupled to the handle;
- a rope force sensor configured to indicate a rope force on a rope supporting the bucket and the handle;
- one or more position sensors configured to indicate a current shovel position;
- and
- a controller including an electronic processor and a memory, the controller coupled to the rope force sensor and to the one or more position sensors, the controller configured to:
- receive rope data indicative of the rope force from the rope force sensor,
- receive position data indicative of the current shovel position from the one or more position sensors,
- determine a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and
- provide the payload mass to a display device associated with the mining shovel.
A method of determining a payload mass for a mining shovel, the method comprising:
- receiving, at an electronic processor, rope data from a rope force sensor indicative of a rope force on a rope supporting a bucket and a handle of the mining shovel,
- receiving, at the electronic processor, position data from one or more position sensors indicative of a current shovel position of the mining shovel,
- determining a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and
- providing the payload mass to a display device associated with the mining shovel.
A control system for a mining machine having a base, a handle rotationally coupled to the base, a bucket coupled to the handle, a rope force sensor configured to indicate a rope force on a rope supporting the bucket and the handle, one or more position sensors configured to indicate a current shovel position, the control system comprising:
- an electronic controller including an electronic processor and a memory, the electronic controller coupled to the rope force sensor and to the one or more position sensors, the controller configured to:
- receive rope data indicative of the rope force from the rope force sensor,
- receive position data indicative of the current shovel position from the one or more position sensors,
- determine a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and
- provide the payload mass to a display device associated with the mining shovel.
