Remotely Addressable Buttons with Can-Bus Data Path in Elevator Applications

Abstract

CAN-Bus and its derivatives are widely used in many applications. In this study, CAN-Bus communication has been specifically developed for elevator buttons. Traditional elevator buttons have numerous cables to communicate with the control panel. However, buttons only help us call the elevator. Old-type buttons in high-rise buildings have a large number of cables. A large number of cables frequently cause malfunctions. CAN-Bus is a solution to reduce the number of cables. In contrast, faulty buttons based on CAN-Bus communication are irreparable due to software programming. This study presents a new button style that can be dynamically readdressed remotely and locally. Reducing the number of buttons provides significant efficiency in sales and profitability in the market. Data transmission based on the CAN-Bus also offers convenience in addressing and interactive solutions. In case of a malfunction, easy access to the button, reduced wiring, energy transmission on high floors, and cost savings are achieved. This system aims to design a low-cost and modular system that communicates via the CAN Bus, displaying information from multiple data sources (speed, temperature, fault codes, etc.) on a dot matrix display in real-time. Furthermore, CAN Bus communication dot matrix indicators provide ease of use in elevator systems for floor information, direction, error messages, and faults and current status occurring in the systems. It provides data transmission to passengers both inside and outside the cabin.
