Abstract

Postupak za bežičnu detekciju prisustva ljudi korišćenjem inkrementalnog određivanja baznih komponenti snaga radio signala i rasplinute logike, koji se odvija u zatvorenom prostoru 150 u okruženju bežične senzorske mreže sa N bežičnih čvor-senzora koji razmenjuju poruke bežičnom vezom 208, 370 između sebe, pri čemu postupak uključuje fazu 209 formiranja i obrade matrice snaga primljenih radio signala za dati vremenski interval karakterisan time da navedeno inkrementalno određivanje baznih komponenti snaga radio signala u fazi (209) uključuje korak (400) prikupljanja odbiraka snage radio signala sa svakog čvora (110, 120, 130, 140), korak (410) određivanja prve bazne komponente navedene matrice snaga primljenih radio signala pri čemu se zatim u koraku (420) računa srednja vrednost (443) i standardna devijacija (442) nakon čega se u koraku (441) formiraju dve ulazne veličine za Mamdani regulator rasplinutog zaključivanja, gde je prva ulazna veličina srednja vrednost (443) niza najznačajnijih baznih komponenti, a druga ulazna veličina je standardna devijacija (442) niza najznačajnijih baznih komponenti nad istim vremenskim intervalom i gde je konačna detekcija prisustva osobe u koraku (451) izlaz iz Mamdani mehanizma zaključivanja, takav da predstavlja signal (433) sa kontinualnim opsegom vrednosti od „0", koja odgovara situaciji kada je prostorija (150) prazna, ili signal (434) sa vrednosti „1" kada je detektovano prisustvo osobe.Prijava sadrži još 1 nezavisan i 7 zavisnih patentana zahteva.A method for wirelessly detecting human presence using incremental determination of the base components of radio signal strengths and fuzzy logic, which takes place indoors 150 in a wireless sensor network environment with N wireless node sensors exchanging messages wirelessly 208, 370 among themselves, the method includes a phase 209 of forming and processing a matrix of received radio signals for a given time interval, characterized in that said incremental determination of the base components of the radio signal strength in phase (209) includes the step (400) of collecting radio signal power deductions from each node (110, 120, 130 , 140), step (410) of determining the first base component of said matrix of received radio signals, in which step (420) then calculates the mean (443) and standard deviation (442) after which two inputs are formed in step (441). sizes for the Mamdani fuzzy inference controller, where the first input size is the mean boil the second input magnitude is the standard deviation (442) of the series of significant components over the same time interval and where the final detection of the presence of a person in step (451) is the output of the Mamdani inference mechanism such as to represent a signal ( 433) with a continuous value range of "0" corresponding to the situation when the room (150) is empty, or signal (434) with the value "1" when the presence of a person is detected. The application contains 1 more independent and 7 dependent patent claims.
