The matrix field-forming system of the Relaxmag magnetic therapy complex contains 48 intelligent, unified cell modules, each with four independently controlled inductor-electromagnets. During setup, technical testing, and repair of the cell modules, operational monitoring of their performance and automated verification of the accuracy of setting and regulating the key biotropic parameters of the generated magnetic fields, such as magnetic induction, various time characteristics, and phase relationships, are required. Since ready-made, compact, and multi-channel solutions for such technical means are currently unavailable, their development is necessary.

Objective – to demonstrate the feasibility of implementing a compact four-channel magnetovisor, which monitors dynamic magnetic fields simultaneously emitted by four independent inductors of the Relaxmag chronomagnetotherapy cell module for monitoring and verifying their proper functioning.

A compact automated magnetovisor prototype based on three-component Hall sensors, an I²C bus multiplexer, and a microprocessor module was developed, manufactured, and tested. It monitors the proper operation of the magnetically emitting cell module of the Relaxmag chronomagnetotherapy system. The magnetovisor prototype board is structurally compatible with the board and dimensions of the cell module. The software is implemented in the Arduino IDE (for the microcontroller) and LabVIEW 2016 (for recording and visualizing magnetic fields on a personal computer). Field tests of the magnetovisor with a real cell module confirmed the correct recording of bipolar pulsed magnetic fields with specified amplitude, time, and phase parameters, simultaneously emitted by the cell module's four inductors.

The magnetovisor is planned for implementation at the Kasimov Instrument Plant, the manufacturer of the Relaxmag complex, to improve automation of cell module function monitoring, debugging, adjustment, and configuration.
