First of all, the design of solar street lamp controller needs to consider the following aspects:
1. light sensor: the light sensor is used to detect the light intensity of the surrounding environment and control the brightness of the street lamp according to the change of light intensity. Commonly used optical sensors include photoresistors and photodiodes.
2. Control circuit: The control circuit is the core part of the solar street lamp controller, which controls the brightness of the street lamp according to the signal of the light sensor. The control circuit can be realized by single chip microcomputer or logic gate circuit.
3. Battery and charging circuit: The solar street lamp controller needs a battery to store the electric energy generated by solar energy for night use. At the same time, it is necessary to design a charging circuit to convert solar energy into electric energy and store it in the battery.
4. brightness level circuit: the brightness level circuit is used to adjust the brightness of the street lamp according to the change of light intensity. The brightness can be adjusted by changing the current or changing the voltage.
Secondly, the realization of solar street lamp controller needs the following steps:
1. Hardware design: According to the above design requirements, select appropriate lighting sensor, control circuit, battery and charging circuit, and carry out circuit connection and layout design.
2. Software programming: If single-chip microcomputer is used as the control circuit, software programming is needed to write the control algorithm and brightness level program. The program can control the brightness of the street lamp according to the signal of the light sensor, and realize the control of charging and discharging.
3. Debugging and testing: After the hardware design and software programming are completed, debugging and testing are needed to ensure the normal operation of the solar street lamp controller. We can observe whether the brightness of street lamps can be adjusted automatically by simulating the change of light intensity.
Finally, the design and implementation data of solar street lamp controller can be obtained through the following ways:
1. online search: you can find a lot of information about the design and implementation of solar street lamp controller on the internet, including design principle, circuit diagram, program code, etc.
2. Professional books: Books about electronic design and solar energy applications usually contain information about the design and implementation of solar street lamp controllers, which can be obtained by reading relevant books.
3. Academic papers: Some academic journals and conferences may have research results of solar street lamp controllers, and relevant materials can be obtained by consulting academic papers.
In a word, the design and implementation of solar street lamp controller need to consider the light sensor, control circuit, battery and charging circuit. , and relevant information can be obtained through online search, professional books, academic papers, etc.
