基于DSP的电弧式弓网离线检测系统

DSP Based Arc Detection System for Dewirement between Pantograph and Catenary

利用电气化铁路中弓网离线电弧的光谱特性,设计了一种应用紫外传感器和DSP技术相结合的检测系统,实现了对弓网电弧的非接触检测,从而得到准确的弓网离线情况,并且对系统的硬件及软件进行了设计,最后对系统仍需完善的部分进行了总结。

In order to acquire exact contact loss informations between the pantograph and the overhead line in the electrified railway,this paper designs a measurement system based on UV-phototube and DSP to detect whether the pantograph contact lose from the contact. What＇more,the hardware and software designs of system is detailedly axplained,at last,this paper summarizes the significant designs during the course of reseach and development.
