Line state testing method and line state testing device

The invention discloses a line state test method and a line state test device. The line state test method comprises the following steps: transmitting an electromagnetic signal to an area where a target line is located; determining whether the target line outputs a voltage signal, wherein the voltage signal is generated by the target line based on electromagnetic signal induction; determining that the target line is conducted under the condition that the target line outputs the voltage signal; and under the condition that the target line does not output the voltage signal, determining that the target line is not conducted. According to the line state test method, the problem that the operation is inconvenient when the on-off test is carried out on the line with one closed end in the prior art is solved. 本发明公开了一种线路状态测试方法及线路状态测试装置，线路状态测试方法包括：向目标线路所在的区域发射电磁信号；确定目标线路是否输出电压信号，电压信号由目标线路基于电磁信号感应产生；在目标线路输出电压信号的情况下，确定目标线路导通；在目标线路未输出电压信号的情况下，确定目标线路未导通。本发明的线路状态测试方法解决了现有技术中对一端封闭的线路进行通断测试时操作不方便的问题。
