The Development Of A Detecting System For The Electric Operator Of Helicopter Based On Virtual Instrument

The research of virtual instrument detecting system about the electric operator is introduced in this paper.This system overcomes the defects of low automation, low detecting precision , the high impacting of human elements and uses the technology of electron, sensor, single-chip computer and computer software to complete the detection for the electric operator and landing light automaticly.This system can be composed with three parts-the hardware, the software and the working table. The working shelf can be designed for fixing and positioning according to the space structure of the mechanics. This shelf achieves the dynamic simulation of working environment and habitus. The displacement measure can be obtained by the precise sensor and the circuit of adjusting.The mensurement accuracy is about 0.02mm. This value is 0.008% of the full range in this system. The break force, locking force and break moment can be loaded automaticly and adjusted freely by closed loop control system. The mensurement accuracy is about 1N and also achieves 0.4% of full range. The technology of separated electricity can be used to solve the controlling and driving of the loading light and measure the high-current. The software of this system solve the problems of saving, measuring method and improve the nature for the antijamming by human. Meanwhile the technology of multi-threading can be used to realize the concurrent processing and improve the ability of real-time.This paper discussed the integral design scheme of this system and mainly introduced the measuring method of the parameter, the design of the circuit. The design methodology of the procedure son-module has been introduced in software.At the present time, this system has been identified by the relative department of measurement and has been used for half a year. It is said that all kinds of parameters are...
