W pracy zaprezentowano przykładowe zastosowanie urządzenia WiViD do diagnostyki stanu maszyn. Pokazano, iż urządzenie to wykorzystuje moduł komunikacji bezprzewodowej do akwizycji sygnału z pomiarów. Przedstawiono skuteczność zastosowania wbudowanych funkcji pomiarowych w systemie WiVID do diagnostyki stanu technicznego sprężarki śrubowej i przekładni zębatej oraz wykazano, że uniwersalne funkcje pomiarowe w systemie WIVID umożliwiają opracowanie indywidualnych metod diagnostyki maszyn złożonych.
In the paper exemplary applications of the WiViD device to machine diagnostics are described. The basic working element of the system is a wireless, multi-channel measurement card placed in the ergonomic housing (resistant to any damage). The measurement head allows for making measurements of vibrations in three directions (mutually perpendicular), within a very wide band of frequency (0.4Hz -20kHz). The scope of the application can be even wider due to the possibility of connecting an external multi-purpose gauge of CLPS type which could be i.e.: gauge of vibrations, gauge of forces, microphone as well as connecting the signal of phase indicator. All measurements are taken in a synchronous way. Additionally, the device may serve as a mini thermo-vision camera. The thermal view/pictures can be presented by means of point resolution 16x4, for the temperature range -50 C to 300 C. The second element of the system consists of a Smartphone or a tablet working under control of the operational system Android version 4.x. The specialized software gathers (collects, stores) measurement information in the mobile data base and after processing, the adequate data are presented on the screen in a clear and concise form. The program integrates the tool kit (procedures) for an evaluation of technical state of machine elements as for example: bearings or elements of the system of drive transmission. In the paper some examples of application of the afore described device to diagnostics of compressors and gears are shown. For the evaluation of the technical state of a gear – during its exploitation - the adequate procedure was prepared. The procedure consists in determination of the thresholds of statistical point estimates of the vibration signal measured on the housings of bearings for a particular gear. Moreover, the evaluation procedure of the overall technical state based on the afore determined thresholds - was formulated. Own software applications dedicated to the measurement analysis of the technical state of the machine were written. The original expert system (worked out by the authors) was prepared. It supports the assessment of the state of the device. - Źródło:
