Danfoss is a project, which is made for analogue signal analysis that comes from the measuring instrument. It measures the hole diameter of engine stators, which are produced in this factory, very precisely.
The system is installed on five stations. Each station has a PC, which is enclosed in an industrial housing. These computers contain series M cards, which are produced by National Instruments and have 16 bit accuracy. This means that we get a very precise interpretation of the analogue signals. Systems enable arrangement of measuring results into groups, which are defined in advance by the person placing the order. This is done in a way that they adjust to settings with the help of calibers. Calibers are made very precisely and are put on the calibration board, which is detected by digital outputs by the measuring system. All measuring results are stored in files, which are also accessible from the central system. This means that the measurements in the entire production are completely transparent and can all stations be analyzed on one computer.
Besides saving measuring results in files on local computers, the system enables overview of results on user interfaces, where the current measurements are shown as graphs and as numbers that are visible to the operator in the production line. All systems are very robust and operate 24 hours per day and are also made in a way that an upgrade of the systems is very simple. It is upgradeable with the help of modules, which we add in the programming language LabView, which is made by National Instruments.
