具有电磁波检测功能的晃眼防护装置
摘要：
本发明涉及具有电磁波检测功能的晃眼防护装置，为解决以往一字形形态在特定方向发生误操作的问题，由2个以上线圈组成电磁波探测装置，拓宽了纵向和横向的测定空间，从而能够准确探测电磁波。本发明特征是包括：光学检测装置、电磁波探测装置、电磁波检测装置、用户界面、主控制装置、以及透光控制装置；其中，光学检测装置检测焊接或切割作业中产生的弧光；电磁波探测装置通过2个以上线圈探测焊接或切割作业中产生的电磁波；电磁波检测装置将通过电磁波探测装置输入的共振信号与可变设定的基准值进行比较；用户界面包括选择或表示上述光学检测装置及电磁波检测装置中某一个的显示装置；主控制装置在光学检测装置检测到弧光时向电磁波检测装置发出电磁波检测装置启动信号，监测从电磁波检测装置输出后输入的电磁波信号变化，并输出监测结果；透光控制装置根据主控制装置的输出信号控制晃眼防护板的透光率。
摘要（英）：

An anti-glare eye protection apparatus includes an anti-glare eye protection plate, an optical detector, an electromagnetic wave sensor, an electromagnetic wave detector, a user interface, a main controller, and a light transmittance controller. The electromagnetic wave sensor senses an electromagnetic wave generated by a welding or cutting torch using at least two coils. The electromagnetic wavedetector compares a signal received through the electromagnetic wave sensor with a reference value. The user interface includes a display for selecting or displaying one of the optical and electromagnetic wave detectors. The main controller applies an electromagnetic wave detector activation signal to the electromagnetic wave detector as the optical detector starts optical detection and monitors changes in a received electromagnetic wave signal based on output of the electromagnetic wave detector. The light transmittance controller controls change in light transmittance of the eye protection plate according to a signal output from the main controller.
