Low-voltage line monitoring method and system applied to low-voltage junction box

The invention discloses a low-voltage line monitoring method and system applied to a low-voltage junction box, and relates to the technical field of low-voltage line monitoring. In response to a received low-voltage line monitoring request, the low-voltage junction box and a low-voltage line corresponding to the low-voltage line monitoring request are determined, and working condition data of the low-voltage line are obtained through the low-voltage junction box; generating a first monitoring result according to a comparison result of temperature data in the working condition data and a preset standard temperature threshold value, calculating terminal load impedance of the low-voltage line through the working condition data, generating a second monitoring result according to a comparison result of the terminal load impedance and a preset standard impedance threshold value, and monitoring the low-voltage line based on the first monitoring result and the second monitoring result. And determining monitoring info
