A method for phase detection of street lights

Abstract

The invention relates to the field of intelligent streetlamps, in particular to a streetlamp phase detecting method. The method includes: an integrated controller detects the zero crossing point of the A phase of a three-phase power supply circuit; the integrated controller transmits a phase detecting data frame to the single-lamp controller of each first-level streetlamp node so as to detect and collect the phase where the single-lamp controller of each first-level streetlamp node is located; the integrated controller transmits a phase detecting data frame to the single-lamp controller of each second-level streetlamp node so as to detect and collect the phase where the single-lamp controller of each second-level streetlamp node is located; ...; the integrated controller transmits a phase detecting data frame to the single-lamp controller of each N-level streetlamp node so as to detect and collect the phase where the single-lamp controller of each N-level streetlamp node is located. By the streetlamp phase detecting method widely applicable to streetlamp intelligent management, the phase where each streetlamp in a streetlamp network is located can be automatically detected.

Description

technical field [0001] The invention relates to the field of intelligent street lamps, in particular to a phase detection method for street lamps. Background technique [0002] During the installation of street lamps, the installers need to ensure that the street lamps can be evenly distributed in each phase of the three-phase power supply line, otherwise it will cause adverse consequences such as reduced power consumption efficiency and uneven illumination of street lamps. Contents of the invention [0003] In order to solve the technical problem that the street lamp management system automatically detects the phase of each street lamp, the present invention proposes a street lamp phase detection method, which includes the following steps: [0004] S1, the centralized controller detects the zero-crossing point of phase A in the three-phase power supply line; the single-lamp controller detects the zero-crossing point of the power supply phase where it is located; [0005]...
