A remote control method and device for led street lamps

Abstract

An embodiment of the invention discloses a method and a device for remotely controlling an LED streetlamp. The streetlamp is remotely controlled in a communication-free manner by using a high-voltage direct-current power supply for driving the streetlamp as a signal source, the service life of the device can be greatly prolonged, and reliability of the device can be greatly improved. The method includes the steps: initializing a system; regulating voltage signals according to preset regulating rules; starting analog-digital conversion and serial timing sampling for the voltage signals; acquiring serial timing sampling results after completing serial timing sampling; respectively averaging the timing sampling results corresponding to gears to serve as a gear reference value; starting a next time of analog-digital conversion; and judging whether reference sampling time comes or not when completing analog-digital conversion, comparing analog-digital conversion results with the gear reference value to obtain comparison results and refreshing a duty ratio according to the comparison results if the reference sampling time comes, and reading the analog-digital conversion results and starting a next time of analog-digital conversion if not.

Description

technical field [0001] Embodiments of the present invention relate to the field of road lighting, and in particular to a method and device for remote control of LED street lamps. Background technique [0002] Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. High-pressure sodium lamps emit 360 degrees of light. The disadvantage of large light loss has caused a huge waste of energy. Compared with traditional street lights, LED street lights not only have the characteristics of good chromaticity, maintenance-free and long life, but more importantly, they are more energy-efficient than traditional street lights. This is especially important today when energy supply contradictions are increasingly prominent. [0003] There are two main control methods for existing LED street lamps. One is the single-lamp control method, that is, each LED street lamp controller only controls one LED street lamp, and the LED street...

Problems solved by technology

[0003] There are two main control methods for existing LED street lamps. One is the single-lamp control method, that is, each LED street lamp controller only controls one LED street lamp, and the LED street lamps need to be controlled one by one during work. In the case of a large number of street lamps, the control and detection of LED street lamps will become cumbersome and error-prone. At the same time, it will consume a lot of manpower and material resources, resulting in serious waste.

[0004] The other is to control a single LED street lamp or the entire LED street lamp group through wireless communication control. Compared with the first method, this method can control the entire LED street lamp system more conveniently and directly, but due to this method It is necessary to install a wireless communication module in the LED street light system, which will make the LED street light system even larger, and this control method is relatively complicated and has low reliability
