AI Technical Summary

Technical Problem

When the existing drain data recording device detects liquids in absorbent materials or items containing absorbent materials, the power consumption is high, resulting in a shortened battery life and it is difficult to effectively manage the use and replacement of absorbent items.

Method used

A drain data recording device is designed, including a connector and a data processor connected to a sensor array, which consists of a plurality of sensor areas, which is configured to store acquisition information and read out the information of the sensor area during the acquisition cycle to determine the filling state. If the sensor area indicates a fill state above the threshold, the acquisition information is changed to reduce the number of read sensor areas and save energy.

Benefits of technology

By optimizing the acquisition information and changing the acquisition cycle, the power consumption of the excretion data recording device is effectively reduced, the battery life is extended, and the management efficiency of the filling state of absorbent items is improved.

Abstract

An excretion data recording device comprising a connector to a sensor array comprising a plurality of sensor regions arranged to sense a fill state of an absorbent material in the vicinity of a corresponding one of the sensor regions, and a data processor, the data processor is configured to store acquisition information indicating at least one of the sensor regions to be read out during an acquisition period; reading out the at least one sensor region indicated by the acquisition information during the acquisition period and via a connector while the sensor array is connected to determine whether the read-out sensor region indicates a higher-than-threshold fill state of the absorbent material in the vicinity of the read-out sensor region, and if the read-out sensor region indicates a higher-than-threshold fill state of the absorbent material in the vicinity of the read-out sensor region, reading out the at least one sensor region during the acquisition period and via a connector. And if it is determined that the read-out sensor region indicates a fill state above a threshold, altering the acquisition information such that it indicates that a previously read-out sensor region is not read out during a subsequent acquisition cycle.
