Embodiment 1

[0017] Such as figure 2 As shown, the street lamp phase detection method of the present invention includes the following steps:

[0018] 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;

[0019] S2, when phase A occurs from positive to negative zero crossing, the centralized controller sends a phase detection data frame to the single lamp controllers of all first-level street lamp nodes to detect and collect the data of all first-level street lamp nodes under the jurisdiction of the centralized controller The phase where the single lamp controller is located; in the present invention, the node where the single lamp controller directly communicates with the centralized controller is called a first-level node. The node where the single lamp controller can communicate with the centralized controller is called a ...

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]...
