Latest Patents

One of Nakayama's latest patents is an excavation control system for hydraulic excavators. This system includes a global coordinate computing device, a prediction correcting part, a cutting edge position data generating part, and a designed terrain data generating part. The global coordinate computing device generates revolving unit orientation data that indicates the orientation of a revolving unit. The prediction correcting part generates corrected revolving unit orientation data by predictively correcting the revolving unit orientation data based on a delay time and revolve angle speed data. The cutting edge position data generating part generates cutting edge position data that indicates the position of a cutting edge based on reference position data, the revolving unit orientation data, and the corrected revolving unit orientation data. Additionally, the designed terrain data generating part generates designed terrain data based on the cutting edge position data and stereoscopic designed terrain data.

Another notable patent is a working machine management system. This system enables users sharing the same working machine to mutually monitor the usage state by each user. The server receives user IDs, working time, engine cooling water temperature, and current position detected in the working machine through a satellite communication network. It calculates the usage time, usage location, load amount, and usage proportion for each user. The server sends warnings to user terminals when the usage time or location is not as planned, or the load amount is excessive. It also allocates maintenance costs of the working machine automatically between users according to their usage proportions.
