Solution Overview

Problem

Conventional systems for monitoring refuse container fill levels provide limited optimization for waste collection routes, as they rely on simple fill level measurements and cannot accurately predict when containers will reach specific fill levels, leading to inefficient resource allocation and unnecessary emptying or refilling.

Innovation Solution

A device and system that utilize level sensors to determine current fill levels, transmit data to a control center, and analyze fill rates to predict future fill levels, allowing for more precise optimization of collection schedules and resource allocation, including the use of historical data, seasonal, and environmental parameters.

1Device complexity

If conventional systems use simple fill level measurements to determine when containers need emptying, then the system complexity is low, but the route planning optimization is limited and trucks may still make unnecessary trips

Engineering Contradiction:

AI summary

The device (3) has a level sensor (4) which determines the current filling level of the material (6). A telecommunication unit transfers the determined filling level data to the control center. A filling rate analysis unit detects and/or determines the fill rate parameter, by which the filling rate analysis unit creates the predicted filling parameters. The filling parameters are transferred to the control unit through the communication unit. An independent claim is included for system for monitoring filling level of material treated to empty or to collection point in container.
