Abstract

The invention discloses a low-voltage-user power transmission line series detection system. The system comprises a host and a slave machine. The host is installed at a total power transmission line and inputs a detection signal to a room power transmission line. The slave machine sends a room identification signal to be detected to the host. When the slave machine is installed at the power transmission line of the room to be detected, the host detects a detection signal change of a corresponding power transmission line and the host determines whether series is generated according to whether an identification signal of the power transmission line corresponds to a room identification signal. The invention also discloses a series detection method. The host inputs the detection signal to the power transmission line of the room from a low-voltage-user total power transmission line. The slave machine sends the room identification signal of the low voltage user to be detected to the host. The identification signal of the power transmission line where the detection signal changes is compared to the room identification signal sent by the slave machine so as to determine the series. The system and the method in the invention possess advantages that operation is simple and the detection is rapid and accurate.
