NSTU Creates a Device for ’Smart Diagnostics’ of Electrical Equipment

Unlike analogues, it not only signals a malfunction but also determines its cause.

The Department of Radio Engineering and Electronics of Novosibirsk State Technical University (NSTU) was reported to have developed prototypes of the innovative digital device for diagnosing DC power converters both in use and in production. The commissioner for the research is Aeroelektromash, a manufacturer of electrical equipment for aviation and space engineering.

The novel smart remote control is compatible with all built-in power supply systems of household and industrial appliances based on static converters, reports the Press Office of NSTU. The device does not require skilled personnel to maintain it, as, contrary to existing diagnostic systems, the converters are monitored and troubleshot automatically.

While designing the device, we decided to implement an intelligent control system straight away. Thereby we improved user experience and expanded the service functions of our solution. By having done so, we enabled an average person without professional engineering qualification to check the converter units step-by-step and thus solve the problem on their own. Our smart remote significantly simplifies and speeds up the diagnostic process; hence, the reduced cost of manufacturing and operating converters," says Dmitry Shtein, the project supervisor, senior lecturer at the Department of Electronics and Electrical Engineering, Deputy Director of the Institute of Power Electronics at NSTU.

Timely detection and accurate determination of the failure cause early on in some cases allow avoiding costly repairs. The tester's work stems from the exchange of digital and analogue signals between the analyser itself and the testable device. NSTU's researchers have developed special analysing programs to process the response signals the diagnostic device receives.

Let us remind that a group of scientists from Tomsk Polytechnic University, joined by their colleagues from Japan-based Gifu University, have developed and successfully tested an ultra-small Teflon antenna for next-generation 5G telecom networks.
