Choosing of input signals means from contactless sensors in the personal computer in real time at the definition of fluctuation parameters of gas-turbine engines blades

摘要

In the article are considered 4 essentially of different way to input signals from analog sensors in a PC, the advantages and disadvantages that ways. The features to input signals with reference to the task of parameters determination gas-turbine blades vibration are described. The way permitting to execute input 4 signals from sensors in a PC in real time simultaneously by means 2 sound cards with reference to the solving task by an optimum way is offered.
