Abstract
The purpose of this paper is to propose a modern and efficient solution for controlling and analysing RS-485 communication networks, overcoming the limitations of traditional methods. In high-voltage systems, isolating RS-485 nodes is essential to protect both circuits and human operators from high voltages and transient phenomena. Conventional solutions, such as high-speed optocouplers and transformers, are effective but require numerous external components, resulting in bulky devices with high production costs. The proposed solution introduces a rechargeable, battery-powered control device operated wirelessly via a smartphone or laptop. This ensures complete isolation for the operator while simplifying the system’s design.
Compared to traditional galvanic isolation methods, this solution significantly reduces production costs and device size, with the total size being comparable to a computer mouse. It offers a cost-effective, compact, and future-ready alternative for industrial applications requiring efficient communication and safety in high-voltage environments. Additionally, the integration of IoT technology enhances functionality by enabling remote monitoring, real-time control, and data analysis. This IoT-driven approach supports predictive maintenance and scalability, making it ideal for modern industrial and automation systems.
