Method of device diagnostics, operating status logging and configuration changes

Abstract

The aim of this research is to design a suitable design for a diagnostic device that will periodically monitor and record selected quantities in the device. The diagnostic equipment must be as flexible as possible, as the design will be applicable to all output electronic equipment of this project. This means that the diagnostic design can be applied to all control units, add-on modules or turnstile controllers. Each checked element contains different quantities that are valid for correct diagnostics. Therefore, there is a desire for a uniform design that can be customized based on the device. The data itself should include the exact time and date the measurement occurred. This information should be kept for several years for back diagnosis. Furthermore, the data should be stored primarily on the device with the possibility to transfer it to the PC via the given interface. Baseline states should be available directly on the device for immediate status. This information will be displayed via a small integrated display directly on the PCB. The data itself should be stored on a medium that retains the information even when the power supply is interrupted. The diagnostic part itself should be equipped with a backup battery, which will be functional even after the failure of the primary power supply for possible failure diagnosis. The design should consist of a microcomputer that will record events that can be updated with firmware to accommodate the board's needs. A simple program that visualizes the data for easier diagnostics will be needed to view the recorded data more easily. © 2019, Danube Adria Association for Automation and Manufacturing, DAAAM.
