Transform your smartphone or tablet into a tool for machine condition assessment and diagnostics. mVIDIA is a program designed not only to meet the needs of experienced diagnosticians but also to help newcomers delve into the intricacies of predictive maintenance. Developed in collaboration with diagnosticians, the comprehensive set of analyses and intuitive user interface enables maintenance teams to perform their daily tasks with exceptional efficiency.
The program is compatible with all Alitec devices equipped with a WiFi interface. It is complemented by the VIDIA software installed on PC-class computers. mVIDIA is part of a predictive maintenance system that uses wireless measuring devices and vibration sensors. The latest techniques and software tools have transformed smartphones into diagnostic tools with functionalities, computational power, and analysis presentation capabilities that far exceed other market solutions. The program operates on the Android operating system, receiving vibration signals from measuring devices equipped with a WiFi interface. All our devices are equipped with this feature, including portable ones with an integrated three-axis accelerometer and a simple thermal camera (WiViD), wireless vibration sensors (CL@VE, mVIBE), and stationary devices (DiBOX, HEV-i, SiBOX, COBAD). The wireless connection allows measurements in risky areas and data collection during alarm situations on the memory cards of stationary devices.
You perform only one measurement on an mVIDIA-compatible machine for all analyses defined on it. Its parameters correspond the needs of each analysis, which means spending only a few seconds at the examined component. Even if you forget to define an appropriate diagnostic parameter, you will not have to return to the do it again. The mobile database, along with the plant structure, stores the original time courses. This unique approach allows full use of analyses added even after the measurements are completed. Threshold level analyses can compare results with declared alarm thresholds. Alarm information propagates through the location tree, indicating the path to the damaged components. The type of analysis, its parameters, and threshold values are defined by standards determining the criteria for assessing the technical condition of machines and their components. For selected types of machines, wizards have been prepared that, based on existing standards and considering machine parameters, automatically create a set of analyses assessing their overall technical condition. If no appropriate regulations exist for the examined machine, you can set the alarm thresholds yourself. mVIDIA has a built-in statistical trend analysis module using the 3Σ method to analyze changes in selected parameter values over time. All you need is confidence that during the selected period, the machine was in good technical condition and no critical events occurred.
With the mVIDIA program, you can analyze the vibration signal of machines operating in intermittent cycles. You can trigger the measurement manually or automatically (by setting). After recording a time course lasting a maximum of 32 seconds, it is possible to extract and fully analyze a fragment of it. For users employing their own vibration signal analysis methods, the program offers the option to save the measurement or analysis result to a text file.
mVIDIA works with the VIDIA software designed for installation on PC-class computers in a client-server configuration. Data can be uploaded to the database locally or sent to the server directly after the measurement, using a GSM network connection. The same database stores information from stationary systems.
