Açıklama
50 years of measurement and assessment of strips means extensive experience in the visualisation and analysis of the data. Our visualisation and evaluation software is therefore specially tailored to the needs of strip assessment, for long strips and with a high measurement point density. It offers numerous editing and evaluation modes configured specially for the demands of strip production.
Vollmer offers two basic products:
- VGraph: The comprehensive software for the recording and visualisation of the measurement data with statistical data evaluation and a wide array of options
- VRecoS: The system for the visualisation and recording of data which essentially replaces the paper plotters previously used
The Office option with both products allows later evaluation and editing of the data on other computers in the customer’s works.
VGraph
VGraph is the software package for the recording and visualisation of data with extensive statistical data evaluation options. It synchronously records up to 16 measurement values – for example thickness, width and speed of the strip, rolling force or strip tension – on a production line, stores them and evaluates them statistically.
VGraph
With statistical functions such as histograms, Cp and CpK values and error lists, VGraph provides valuable decision aids for the evaluation and further use of the coil produced.
The diagnostic instruments allow optimisation of the rolling process and the line engineering. The optional FFT analysis detects periodic fluctuations in the strip thickness.
VGraph meets the needs of day-to-day strip production. One example: Random lengths of strip at the leading and trailing ends (drop-off) can be suppressed – even subsequently – in the statistical evaluations.
The data are recorded in real-time – according to length or time – with a variable scanning rate from 1 ms upwards. The display of the measured values can be configured and scaled with a wide range of options. The documentation, such as the quality protocols of the coils produced, can also be variably adapted.
The signals are recorded using a data collector belonging to the scope of supply. Its electronics with input and output modules is designed for installation in switch cabinets or desks in interference-proof 24 Volt top-hat (DIN) rail technology. It transmits the data via a network cable to the Windows recording computer which can be supplied by Vollmer or by the customer.
As an option, Vollmer also offers the Office version of VGraph which allows the data to be accessed from other computers.
VRecoS
In addition to the strip speed, VRecoS also records up to three further tracks, such as the rolling force or the strip thickness at the ingoing and outgoing ends of the mill. The measurement protocols can be stored, printed out and distributed by e-mail.
The measured values can be recorded as a function of both length and time. The recording frequency can be set with a scanning rate of 2.5 ms.
