Abstract

Sposób detekcji obecności i aktywności osoby korzystającej z kąpieli w wannie, która wykonana jest z materiału dielektrycznego charakteryzuje się tym, że wykorzystuje relację składowej urojonej do rzeczywistej w pomiarze impedancji elektrycznej techniką dwu lub czteroelektrodową, przy użyciu wymuszenia prądem przemiennym o częstotliwościach z zakresu do 200kHz, oraz pomiar poziomu kąpieli. W wannie (4) wypełnionej wodą umieszcza się co najmniej dwie zespolone elektrody (11) poniżej poziomu wody. Każda z elektrod wykonana jest w układzie koncentrycznym, przy czym każda jest złożona z elektrody zewnętrznej i elektrody wewnętrznej rozdzielonych warstwą dielektryka, po czym stosuje się różne częstotliwości sygnału pomiarowego, które analizuje się przy pomocy mikrokontrolera lub mikroprocesora, w którym zaimplementowane są w formie programów komputerowych algorytmy detekcji obecności i aktywności osoby w wannie z wodą oraz algorytmy oceny zagrożenia zdrowia lub życia. Układ stanowi realizację sposobu według wynalazku.The method of detecting the presence and activity of a person using a bath tub, which is made of dielectric material, is characterized by the fact that it uses the imaginary to real relationship in the measurement of electrical impedance using the two or four-electrode technique, using AC forcing with frequencies in the range up to 200kHz, and measuring the level of the bath. In the tub (4) filled with water, at least two combined electrodes (11) are placed below the water level. Each of the electrodes is made in a concentric system, each consisting of an external electrode and an internal electrode separated by a dielectric layer, after which different measurement signal frequencies are used, which are analyzed using a microcontroller or microprocessor, in which they are implemented in the form of computer programs algorithms for detecting the presence and activity of a person in a tub of water, and algorithms for assessing health or life threat. The system implements the method according to the invention.
