发明名称 Detecting sump depth of a miner
摘要 Systems and methods for operating a mining machine. One system includes a controller, a stationary object, and a radar device. The radar device transmits radio waves toward the stationary object and detects reflections of the radio waves. The controller obtains timing information regarding the radio waves and the reflections. Based on the timing information, the controller is configured to determine a first distance between the radar device and the stationary object before sumping the mining machine into material and a second distance between the radar device and the stationary object after sumping the mining machine into the material. The controller is also configured to determine a sump depth of the mining machine based on the first distance and the second distance, compare the determined sump depth to a predetermined sump depth, and perform at least one automatic action when the determined sump depth does not satisfy the predetermined sump depth.

主权项 1. A system for operating a mining machine, the system comprising: at least one controller configured to obtain first reflection data from at least one radar device,determine, based on the first reflection data, a first distance between a point of reference and a stationary object before sumping the mining machine into material,obtain second reflection data from the at least one radar device,determine, based on the second reflection data, a second distance between a point of reference and the stationary object after sumping the mining machine into the material,determine a sump depth of the mining machine based on the first distance and the second distance, andperform at least one automatic action when the determined sump depth does not satisfy at least one predetermined sump depth.
