AI Technical Summary

Technical Problem

After the disinfectant evaporates, the sensors in hospital toilets cannot distinguish the smell of disinfectant from the smell of feces or urine, resulting in the inability to trigger the cleaning call in a timely manner and poor call effectiveness.

Method used

A multi-sensor fusion system is adopted to analyze the time-series data of the status changes of the door magnetic sensor and the flushing sensor, and combine them with ventilation and environmental data to generate a dynamic pollution situation field, identify pollution focus and generate cleaning urgency, and finally generate a cleaning call command.

Benefits of technology

In the complex environment of disinfectant evaporation, accurately sensing the hygiene status of toilets can improve the accuracy and reliability of cleaning calls and optimize the efficiency of cleaning resource allocation.

Abstract

The present application relates to the field of calling technology, and discloses a toilet cleaning precise calling system and method based on multi-sensor fusion, which comprises an analysis unit, an attenuation unit, a diffusion unit, a global analysis unit, a pollution unit and a cleaning calling unit. The technical solution breaks through the limitation of traditional odor sensor relying on odor judgment, calculates the global attenuation coefficient by combining the behavior mode of the toilet event and the pollution load value, dynamically analyzes the diffusion law of pollutants, can avoid the interference of disinfectant, dynamically adjusts the stable confirmation time length and the state recovery time length, prevents the pollution from triggering the calling system temporarily, avoids the calling system not being withdrawn in time after the pollution is relieved, solves the calling failure problem caused by disinfectant covering up the odor in the hospital toilet, and improves the timeliness and accuracy of the cleaning calling response.
