Intelligent road lamp controller

Abstract

The invention relates to an intelligent street lamp controller, belonging to the technical field of the electrical control equipment. The invention aims at providing an intelligent street lamp controller which can automatically control the turning-on and the turning-off time of street lamps, gradually reduce the voltage and supply power to the street lamps in accordance with the lighting requirements at night, and can gradually reduce the number of the street lamps for lighting without affecting the normal lighting at night. The invention has the technical proposal as follows: a plurality of autotransformer series windings respectively and periodically controlled by a zero line AC contactor and a multiplex street lamp AC contactor which can periodically cut the power supply of the multiplex street lamps are provided to meet the requirement of the lighting of the street lamps under the lowest voltage and the practical requirement of the lighting of the street lamps at night; the autotransformer series windings and the multiplex street lamp AC contactor are adjusted and controlled by a programmable controller and a time controller; therefore, the street lamps can be periodically and automatically turned on and off, and the autotransformer can gradually reduce the voltage and supply power to the street lamps to gradually reduce the number of the street lamps for lighting; the invention can reduce the power energy by 20 percent to 60 percent, and has obvious power-saving effect.

Description

technical field [0001] The invention relates to an intelligent street lamp controller, which belongs to the technical field of power control equipment. Background technique [0002] With the development of urban road lighting and landscape lighting, the issue of power consumption has been paid more and more attention by governments at all levels. Many cities are facing the situation of power shortage, and often adopt the control method of turning off the lights at intervals or at midnight for street lighting. Accidents and induced crimes occur. There are also some cities that use methods such as saving motors, reactive power compensators, and electronic ballasts to save energy. Although they can also achieve a certain energy-saving effect, they cannot stabilize the voltage on the lighting fixtures, and at the same time generate harmonic interference, which reduces the lamps. service life, increased maintenance costs. The control method is mainly to install a timer in the ...

AI Technical Summary

Problems solved by technology

However, some landscape lights are usually turned on and off by manual control. Due to the lack of flexible control methods, it is difficult to give full play to their due performance.

These methods can neither adjust the time of turning on and off the lights in time, nor can they reflect the operation of the lighting facilities in time, and the failure rate is high and maintenance is difficult.

Moreover, with the continuous development of the city, the control range is getting larger and larger, and the current control method cannot reflect the operation of the lighting facilities in time, making the maintenance work very passive.

Faults during operation can only be discovered by waiting for the inspectors to arrive at the scene, or passively waiting for calls from citizens, so it is difficult to repair them in time
