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

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Sammanfattning : 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. LÄS MER

  3. 2. Floor Guide for Sliding Doors

    Master-uppsats, Lunds universitet/Innovation

    Författare :Elin Friberg; Jennie Walfridson; [2020]
    Nyckelord :Product development; Assa Abloy; floor guide; friction; noise; Technology and Engineering;

    Sammanfattning : This Master Thesis, executed in collaboration with Assa Abloy Entrance Systems, addresses issues and desirable features with the currently used floor guide, and several final concepts, in terms of short-term and mid-term solutions, are presented after following the product development process. The floor guide's main purpose is to keep the door leaves of an automatic sliding door running smoothly on correct track without causing any noise. LÄS MER

  4. 3. Investigation of friction drive for night closing door

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära

    Författare :Sissela Svärd; [2020]
    Nyckelord :Hertzian Contact Pressure; Rolling Friction; Finite Element Analysis; Fatigue; Material; Technology and Engineering;

    Sammanfattning : ASSA Abloy Entrance Systems design and manufacture automatic sliding-, swingand revolving doors. A regular revolving door is often equipped with night closing doors on the outside, which are used to close the entrance when, for example, the store or workplace is closed for the evening. LÄS MER

  5. 4. Automatic Belt Tension Device

    Master-uppsats, Lunds universitet/Innovation

    Författare :Simon Önnered; [2020]
    Nyckelord :Belt tension; timing belt; sliding doors; problem analysis; eccentric; ASSA ABLOY; Technology and Engineering;

    Sammanfattning : In this master’s thesis, the development of a new belt tensioning solution, for use in ASSA ABLOY's sliding doors is treated. As a starting point for the work, ASSA ABLOY’s current belt tension solution has been used as a reference. LÄS MER

  7. 5. Options for Mechanical Hold Force for Sliding Doors

    Master-uppsats, Lunds universitet/Innovation

    Författare :Mikaela Albertsson; Jens Thieme Almkvist; [2019]
    Nyckelord :Sliding doors; Mechanical force; Product development; Ulrich Eppinger; Prototyping; Technology and Engineering;

    Sammanfattning : ASSA ABLOY’s automatic sliding doors today have a constant hold force applied whenever the doors are closed. The force is adjustable between 0-60 N and is generated by a motor. In this project it has been investigated whether it is possible to install a mechanical alternative to this hold force instead. LÄS MER
