Virtuální systém pro měření charakteristiky chladicí trysky

Abstract

This bachelor thesis deals with the design of a virtual system for measuring characteristics of the cooling nozzles in the selected development tool LabVIEW. Through created application, flow rate is measured by the Comac cal flow 38 industrial flowmeter, pressure is measured using a Keller pressure gauge and and weight is measured by the digital Ken scale. Motion of the robotic arm with the cooling nozzle is controlled and the cooling nozzle is opened and closed. Cooling nozzles are used in secondary cooling for continuous casting of steel. All these devices except digital scale are connected to the computer's measurement card. Digital scale Kern communicates via the serial interface that is created by the USB/RS232 interface converter. Entire measurement of the nozzle characteristic is performed in automated mode. On the front panel, LEDs indicate the states in which the robot is located, and user only chooses the option to save the data to the file and the opening time of the nozzle. At the end of the application, a 3D graph with results of the measurement of the nozzle characteristic is plotted.
