LED street lamp system with intelligent remote control

Abstract

The present invention discloses an LED street lamp system with intelligent remote control. The system comprises LED street lamps, single lamp controllers arranged on the LED street lamp, a centralized controller which controls each of the single lamp controllers, and a control center which controls the centralized controller. Each of the single lamp controllers comprises a power supply, a current and voltage acquisition circuit, a switch circuit, a PWM modulation circuit and a first PLC unit. The output end of the current and voltage acquisition circuit and the output end of the switch circuit are connected to the input end of the first PLC unit. The output end of the first PLC unit is connected to the input end of the PWM modulation circuit. The power supply supplies power to the above modules. The centralized controller comprises an MCU micro processing unit, a storage unit, a wireless communication unit, a second PLC unit and a power supply. The storage unit, the wireless communication unit and the second PLC unit are electrically connected to the MCU micro processing unit, and the power supply supplies power to the above modules. The first PLC unit is electrically connected to the second PLC unit. The centralized controller is connected to the computer of the control center through the wireless communication unit.

Description

technical field [0001] The invention belongs to the technical field of electric equipment monitoring, and in particular relates to a remote intelligently controlled LED street lamp system. Background technique [0002] With the development of urban lighting and the need for energy saving and emission reduction, LED is developing rapidly as a new type of lighting source. LED street lamps have the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lamps have become the best choice for energy-saving renovation. At the same time, with the large-scale application of LED street lamps, new requirements are put forward for the information management of urban lighting. At present, most cities use a monitoring system based on GPRS communication technology. This monitoring system can control the opening and closing of lighting distribution cabinets and data collection in the city, and can giv...

AI Technical Summary

Problems solved by technology

[0003]1) Single lamp monitoring cannot be performed, and remote intelligent dimming and detection of LED street lamps cannot be realized;

[0004]2) The communication method is single, mainly using GPRS communication, which cannot integrate 3G and PLC communication;

[0006]4) The maintenance of lamps is troublesome, and all power switches of the entire distribution box are required for maintenance, resulting in waste and dangerous operation;

[0007]5) In addition, when the power line is maliciously damaged or fails to supply power for some reason, the entire street light line cannot be used, which brings inconvenience to people's travel
