[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

[0032] see figure 1 , the first embodiment of the LED street lamp control method in the embodiment of the present invention includes:
[0033] 101. Initialize the single-chip microcomputer;
[0034] Before controlling the LED street lamp, the single-chip microcomputer can be initialized. The above-mentioned initialization operation of the single-chip microcomputer can be to initialize the registers, timers and input and output ports in the single-chip microcomputer. It should be noted that the initialization operation of the single-chip microcomputer is not limited to the initialization of the registers, timers and input and output ports in the single-chip microcomputer described above, and may also include initialization operations required by other connection functions, which are not limited here.
[0035] 102. Load the preset limit reference value of each gear;
[0036] After the microcontroller is initialized, the limit reference values of each gear can be loaded. The ...

An LED street lamp control method and an apparatus use a high voltage direct current power supply for driving a street lamp as a signal source to implement remote control of the street lamp without communication, while greatly prolonging service life of the apparatus and improves reliability thereof. The method in embodiments of the present invention comprises: initializing a single chip computer; loading a preset limit reference value for each gear; initializing an analog-to-digital conversion module and a PWM module; enabling analog-to-digital conversion for a voltage signal; when the analog-to-digital conversion for the voltage signal is complete, reading an analog-to-digital conversion result, and comparing the analog-to-digital conversion result with the limit reference value for each gear to obtain a comparison result; and refreshing a duty ratio according to the comparison result. The method and the apparatus in the embodiments of the present invention use a high voltage direct current power supply for driving a street lamp as a signal source to implement remote control of the street lamp without communication, while greatly prolonging service life of the apparatus and improves reliability thereof.
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 controlling 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 lamps, LED street lamps not only have the characteristics of good chromaticity, maintenance-free and long life, but also more energy-saving than traditional street lamps, which is especially important in today's increasingly prominent energy supply contradiction. [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 on...
