Design and implementation of 1.2m wind tunnel measurement and control system based on PROFINET and VXI bus

In order to solve the flaw of measure and control system in the 1.2m×1.2m wind Tunnel, a new generation of measurement and control system is researched and developed, the paper accounts the technique reform scheme, Mainly design a new system based on PLC and fieldbus technology, using PROFINET communication and VXI system construct the wind tunnel measurement and control system, form a function dispersion, command, centralized open distributed system based on the fieldbus. and defines implementary condition and solved technique in detail, explains commissioning and application condition, finally the main conclusions drawn. the test results demonstrate that this system is good, The new measurement and control system not only improves the automation level of the 1.2 meter wind tunnel test, but also improves the safety and efficiency of the wind tunnel, and the wind tunnel test capability is improved as a whole.
