动圈式检波器芯体极性的一种智能测试方法

A Intelligent Method to Test the Polarity of Moving-coil Detector Core

动圈式检波器在其制造过程中存在芯体极性反接的情况,必须对每一个检波器芯体进行极性校验。介绍了一种对动圈式检波器芯体极性的智能测试方法,利用单片机驱动气缸作为检波器的激励信号,同时采集芯体输出电压值来判断检波器芯体极性,有效避免了检波器芯体极性测试受人为因素干扰而造成的判断失误。该方法是搭建检波器自动化生产线的重要一环,具有易于实现、成本低、准确性高的优点。

The phenomenon of the inversed grafting on the polarity of moving-coil detector core usually occurs when producing moving-coil detector.As a result,every core of detector needs polarity test.In this paper,an intelligent method is introduced for the polarity testing of moving-coil detector core.We applied the air cylinder driven by single chip as the activating signal of detector and utilized the output voltage value of detector core to determine the core polarity.In this way,we can avoid the user bias when testing the polarity of detector core.Polarity test is a significant step when we create the automatic production line.Our method can provide an easy-implemented,low-cost and high-accurate way to achieve polarity test.
