Fig. 1 is a schematic diagram of the basic structure of an intelligent street lamp energy-saving control system based on a single-chip microcomputer of the present invention.

Detailed ways

Please refer to Fig. 1, the intelligent street lamp energy-saving control system based on a single-chip microcomputer of the present invention includes at least: a light-controlled timing switch, an environmental variable measurement device, a wireless signal transceiver circuit, a single-chip microcomputer control circuit, a voltage regulating circuit, and a high-pressure sodium lamp.

The light-controlled timing switch is connected with each street lamp to be controlled, and is used for controlling the illuminance of the street lamp to be controlled, turning on and off of the street lamp to be controlled, and the like.

The environmental variable measuring device is arranged on the road section where each street lamp to be controlled is located, and is used to measure various environmental parameters of the road section where each street lamp to be controlled is located, such as the intensity of sound signal, light intensity, including sunlight intensity, illumination light intensity, etc. Therefore, the environmental variable measuring device may include: a volume sensor, a light sensor, and the like. Through the measurement of the volume sensor, it can sense whether there is a vehicle passing by at night, so as to control the luminous intensity of the street lamp, etc.

The wireless signal transmitting circuit is connected with the environmental variable measuring device, for example, with each volume sensor and light sensor, and is used for wirelessly transmitting the environmental parameters sensed by each volume sensor and light sensor after being processed. In this embodiment, it works in a wide working voltage range of 3-12V, and even when the voltage amplitude changes, its transmission frequency can basically remain unchanged.

The wireless signal receiving circuit is used to receive the data sent by the wireless signal transmitting circuit, because the wireless signal receiving circuit works with the wireless transmitting circuit, so its receiving frequency is consistent with the transmitting frequency of the wireless transmitting circuit.

The single-chip microcomputer control circuit is connected with the wireless signal receiving circuit, which is equipped with a cooling fan (not shown). In this embodiment, an 8051 single-chip microcomputer control circuit can be used to control the entire system.

The voltage regulating circuit is connected with the single-chip microcomputer control circuit and the light-controlled timing switch, and is used to adjust the output voltage according to the control signal output by the single-chip microcomputer control circuit, and then control the dimming value of the light-controlled timing switch, so that the street lamp to be controlled emits corresponding intensity of light.

In addition, if a sodium lamp to be controlled is set on the road section to be controlled, it can also be controlled by the voltage regulating circuit.

The working process of the above-mentioned intelligent street lamp energy-saving control system based on single-chip microcomputer is as follows:

1. In the case of making full use of natural light, turn on the main switch of the road section, that is, the light-controlled timing switch, and each volume sensor, light sensor, etc. send the sound signal and light intensity signal sensed to the wireless transmission circuit, and the wireless transmission circuit transmits it to the wireless transmission circuit. The receiving circuit is sent to the single-chip control circuit by the wireless receiving circuit, and the data input by the single-chip control circuit is used to manage the light intensity of different environments at different times reasonably. On the premise of meeting the illumination requirements and lighting quality, the corresponding voltage regulation value is output to the voltage regulation circuit, so as to control the switch of the street lamp.

2. The single-chip microcomputer control circuit intelligently adjusts the voltage-regulating circuit to control each individual street lamp to maintain a strong illumination during busy hours. When it is close to midnight, it starts to automatically adjust the light. When there are few cars and people in the middle of the night, it automatically adjusts the light according to the driving conditions of the vehicle. If there is no car passing by, the street lights are relatively dim. When a car comes, the street lights in front of it will change from dark to bright, and those street lights will automatically dim when the car passes by. It not only meets the lighting needs, but also saves a lot of electricity.

3. Obtain the corresponding illuminance adjustment rate by measuring the "time-vehicle (person)" statistical law of urban road vehicles and pedestrians, and design the control program of the single-chip microcomputer based on this. According to the illuminance adjustment rate, start from a certain moment to adjust The voltage circuit dynamically adjusts the street lamp input voltage smoothly.

4. According to the lighting principle of high-pressure sodium lamps and road lighting requirements, the optimal voltage value, current, power and overall energy-saving effect of street lamps are measured when they are in a power-saving state.

To sum up, the energy-saving control of intelligent street lights based on single-chip microcomputer of the present utility model can not only automatically turn on and off the main switch of street lights according to the morning and evening of local sunrise and sunset, the actual brightness of cloudy or sunny days; The lights are intelligently controlled. For example, when there is no car passing by in the middle of the night, the street lights are relatively dark. When the car drives, the street lights in front of it will change from dark to bright, and the street lights in front of the car will be dimmed automatically. According to the actual situation of lighting, the dynamic and intelligent management of street lamp voltage and illuminance is realized, and finally the input electric power of street lamps and the actual illuminance requirements are optimally matched. Moreover, the street lamp energy-saving system controlled by this single-chip microcomputer can not only save electric energy, but also stabilize the supply voltage and prolong the service life of street lamps, thereby achieving energy saving in a double sense. The utility model can be widely used in energy-saving control fields such as road and tunnel lighting, building lighting, etc., and intelligent control fields based on various dimming and voltage regulation.
