  1. 1. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Teodor Renman; Charlie Ringström; [2023]
    Keywords : Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Abstract : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. READ MORE
