Research Of On-line Detecting System For Enameled Wire Based On Embedded Linux

It is necessary for enameled wire to check up during production. It is a trend to use the on-line flaw detecting system as a quality control method for enameled wire,but the research and application about this field is barren in our country currently. This paper is devoted to solve this problem. Firstly, this paper introduces the importance of the on-line flaw detecting system for enameled wire, and studies in this field all over the world. Based on analyzing principle of DC high-volt electric field detecting method for enameled wire's continuous coat, this paper discusses the impact to high-volt while enameled wire in the sensor with differern position, and atmosphere condition's impact as well. For detecting different specification enameled wire,this paper also discusses the selection of high-volt and leak electric current and well controlling methods. Expect for detecting method for enameled wire continuous coat,it also explains the method of measuring enameled wire's diameter and detecting particle on enameled wire surface.That is CCD and jiggle switch.According with the request of detecting&controlling system, this paper also discusses system software designing and realizing with VC++ based on PC. After these, considering reducing cost,it brings forward a method based on embedded system to realize detecting.Embedded system has inherent excellence in multi-task and real-time. Further,embedded system hardware is convenient to integrate with enameled wire detection equipment.After explaining the concept of embedded system and the virtue of linux as embedded operating system, this paper discusses the constructing of software and hardware platforms application program's realizing to fulfill on-line flaw detecting for enameled wire.The analysis of the impact to high-volt of enameled wire in the sensor with differern position and atmosphere condition selection of high-volt and leak electric current for detecting different specification enameled wire are innovations of this paper, Adopting embedded system to realize detection for enameled wire is the other.A sample system is made during the research process and the experiment effect is satisfied.
