Abstract
Example embodiments provide an apparatus for monitoring a rock drilling rig. The apparatus may be configured to determine a support pattern of the rock drilling rig and a total centre of gravity of the rock drilling rig. The rock drilling rig may be monitored based on a position of the total centre of gravity with respect to the support pattern. An apparatus, a method, and a computer program are also disclosed.
Claims14
An apparatus for monitoring a rock drilling rig including a plurality of structural components, the apparatus comprising:
- at least one processor;
- and
- at least one memory comprising instructions, which, when executed by the at least one processor, cause the apparatus to:
- receive information on positions of the plurality of structural components of the rock drilling rig in relation to each other;
- receive mass properties of the plurality of structural components;
- determine a local centre of gravity of the plurality of structural components;
- determine a total centre of gravity of the rock drilling rig based on the local centre of gravity of the plurality of structural components, the mass properties of the plurality of structural components and information on positions of the plurality of structural components of the rock drilling rig in relation to each other;
- receive information on ground support members supporting the rock drilling rig, the information comprising at least positions of the ground support members;
- compute a support pattern of the rock drilling rig based on the information on the ground support members supporting the rock drilling rig;
- determine information on stability of the rock drilling rig based on a position of the total centre of gravity with respect to the support pattern;
- detect a risk of instability based on the information on stability of the rock drilling rig;
- cause the rock drilling rig to at least one of limit velocity or stop when the risk of instability is detected;
- and
- output data on the stability of the rock drilling rig.
