Desenvolvimento de hardware e firmware para dispositivo PIck-to-Light

Abstract

The modernization of logistics, driven by the need for efficiency and precision, has led to the development of innovative technologies to optimize storage and picking processes. In this context, PtL emerges as a solution, providing real time visual instructions to operators during order picking, reducing errors, and increasing delivery speed. This technology uses light signals to guide operators in collecting items, offering accurate information about products and quantities required. This work presents the development of a PtL device to optimize the picking process in logistics warehouses. The research addressed the implementation of hardware and firmware compatible with PtL technology, using optical sensors and buttons as mechanisms for detecting item collection. Communication between devices was carried out via the Modbus RTU protocol over a RS-485 network, with a segmented network approach to minimize conflicts. The results obtained demonstrate the feasibility of the developed PtL system in optimizing the picking process. The combination of suitable hardware, firmware, and communication protocols allowed the creation of a solution for industrial environments. The study presents some limitations, such as testing at only two hardware points and the use of a Python environment to simulate the control software. Additionally, item collection detection was implemented using three different techniques, which may be the subject of future research to optimize the choice of the best approach.
