Aero-engine exhaust electrostatic monitoring system based on PXI

Based on the principle and status analysis of aero-engine electrostatic monitoring technology, an aero-engine exhaust electrostatic monitoring system with PXI bus was designed, in addition, hardware platform and software modules design were discussed in detail. Taking PXI computer as system core and combined with NI Labview, the reliability ,flexibility and automaticity to this system are greatly enhanced, from which system cost is reduced accordingly. In actual test, particles produced by fault in aero-engine exhaust can be detected efficiently, resulting in good application effect and wide application foreground.
