AI Technical Summary

Technical Problem

Existing vacuum toilet systems in double-decker vehicles are unreliable as a malfunction in one toilet can shut down both toilets due to shared drainage, despite a potential leak in only one toilet's pipe.

Method used

A control device is used to detect air leaks in separate lines from each toilet bowl to individual isolation valves, allowing the functioning line to remain operational by isolating the faulty line.

Benefits of technology

The system ensures reliable operation by identifying and isolating the source of air leaks, maintaining functionality of one toilet even if the other is malfunctioning, thus enhancing system reliability and efficiency.
