Intelligent and energy-saving streetlamp controller and control method

Abstract

The invention relates to an intelligent and energy-saving streetlamp controller and a control method. The intelligent and energy-saving streetlamp controller comprises a controller power supply switch as well as a singlechip, a D / A (Digital to Analogue) converter, a trigger and a thyristor master controller which are respectively connected with the controller power supply switch and electrically connected with each other sequentially, and a conversion switch is further arranged between the trigger and the thyristor master controller. The power supply switch is electrically connected with a main circuit. The thyristor master controller comprises a first thyristor and a second thyristor which are antiparallel and connected in series in the main circuit. The intelligent and energy-saving streetlamp controller prolongs the service lives of a contactor and a tube, reduces the maintenance amount and has the energy-saving effect.

Description

technical field [0001] The invention belongs to the technical field of electrical control, in particular to a street lamp control device and a method for controlling the street lamp. Background technique [0002] The existing street lamp control device, according to the changing law of the four seasons of the year, uses the longitude and latitude algorithm to calculate the sunrise and sunset time, and fine-tune the switching time. Automatically adjust the opening time in cloudy or sunny conditions to meet the needs of pedestrians. The grid power frequency voltage is used for power supply, and the contactor is used to control the on-off of the power supply. The contactor is closed and the street lamp is turned on, and the contactor is turned off and the street lamp is extinguished. The main circuit is connected in series with the inductance coil, and the electromagnetic adjustment technology is used to adjust the inductance to realize the purpose of adjusting the voltage of ...

AI Technical Summary

Problems solved by technology

[0004] (1) The contactor is used for on-off during the opening and closing process, so the arc of the main circuit is large, the service life of the contactor is short, and the maintenance amount is large

[0005] (2) The inductance of the main circuit series connection is limited. During the on-off process of the contactor, the voltage at both ends of the street lamp changes from zero to a fixed value, and the preheating and cooling process of the lamp tube is short, so the life of the lamp tube is shortened.

[0006] (3) The inductance of the series connection of the main circuit is limited, and the voltage adjustment at both ends of the street lamp is limited. Especially after the grid voltage rises at night, there are few pedestrians, and the illumination of the street lamp needs to be reduced accordingly. However, the current street lamp control device cannot achieve this. function, while the power consumption of street lamps is proportional to the square of the voltage, so the energy saving effect is poor

[0007] (4) The inductance connected in series in the main circuit has its own loss, which wastes non-ferrous metals
