Line detection system for household distribution box

The invention discloses a line detection system for a household distribution box. The line detection system comprises a detection control circuit and single-path gating switches; the single-path gating switches selectively switch on or switch off operation control; the detection control circuit is connected with a household electric meter wiring power grid; the single-path gating switches are connected with the household power grid lines of each household electric meter; and the single-path gating switches are provided with receiving and detecting signal alarm modules. The output end of the detection control circuit emits control signals so as to control the wire outgoing connectors of detected household electric meters of the household distribution box through the single-path gating switches, and therefore, selective switching-on or switching-off control on the detected household electric meters can be realized through the single-path gating switches. The line detection system of the invention is used for de
