Design and Simulation of Structural-Functional and Electrical Schematics of an Acoustic-Enabled Diagnostic Controller

This paper presents the design and modeling of structural-functional and electrical circuits of a diagnostic system (controller) equipped with an acoustic feedback function. The proposed system is intended for medical equipment, particularly hemodialysis devices, to improve the efficiency and responsiveness of diagnostic processes.

The system architecture is based on a microcontroller platform and provides real-time processing of data obtained from analog and digital sensors, visual indication, and generation of acoustic notifications. The paper describes the functional structure of the controller, operating modes, electrical schematic design, and simulation modeling performed in the PROTEUS environment.

Simulation results confirm the functional reliability of the proposed solution and demonstrate its practical applicability in medical diagnostic systems.
