Design and implementation data of solar street light controller

The solar street light controller is a street lamp control device that uses solar power generation, which can automatically adjust the brightness of the street lamp according to the light intensity to achieve the purpose of energy conservation and environmental protection. The following will introduce the design and implementation materials of the solar street light controller.

First of all, the design of the solar street light 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 light according to the change of light intensity. Commonly used light sensors include photoresistors, photodiodes, etc.

2.Control circuit: The control circuit is the core part of the solar street light controller, which controls the brightness of the street light according to the signal of the light sensor. The control circuit can be implemented by single-chip microcomputer or logic gate circuit.

3.Battery and charging circuit: Solar street light controllers require batteries to store the electricity generated by solar power for use at night. At the same time, charging circuits need to be designed to convert solar energy into electricity and store it in batteries.

4.Brightness adjustment circuit: The brightness adjustment circuit is used to adjust the brightness of street lights according to the change of light intensity. The brightness can be adjusted by changing the current or changing the voltage.

First, the wiring method:

1. After connecting the battery, the indicator light of the controller is in a flowing state. (The positive and negative poles are reversed, and the controller does not work).

2. After connecting the load, press the "Adjust" button three times in a row to adjust the time and the load will be on. (The load cannot be short-circuited, otherwise the controller will be damaged).

3. The load is not lit, please check the load, or measure the battery voltage.

4. After connecting the photocell, the load is off, indicating that the photocell is normal, otherwise, please check the photocell.

2. After resetting, enter the startup state. There are two ways to get into normal operation:

After a delay of 60 minutes, it will automatically enter the normal state, and the time is the timing time for the controller to remember the factory test, which is generally 15 hours.

Press the control button three times in a row to force it into the normal state, and press the adjustment button to adjust the timing time.

3. Time adjustment:

1. After connecting the battery, light source and photocell according to the above method, press the reset button, the controller is in a state of running water, press the "adjust" button three times in a row, and start to adjust the timing time, 1h light means that the timing is 1 hour and 2h is bright means that the timing is two hours 1H + 2H is on at the same time, which means that the timing is 3 hours. When it is bright at 4h, it means that the timer is 4 hours. 1h+4h simultaneous lighting means 5 hours, and 2h+4h simultaneous lighting means 6 hours.

1h+2h+4h means 7 hours ......When 1h+2h+4h+8h is fully bright, the system is timed for 15 hours.

KD2412—II LED status indication indicator:

Start-up state: All LEDs form a running water lamp.

Idle status: The green LED is solid and the LED 8421 shows the set time.

Charging phase: red LED flashing, LED 8421 shows set time.

Lighting status: Green LED flashing, LED 8421 shows set time.

Test phase: If everything is in order, the green light is always on.

If the battery is undervoltaged, the red light is always on.

The photocell has no voltage and the yellow light is always on.

Note: The wiring method should be wired according to the diagram marked on the controller. Otherwise the controller does not work.

To solar controller details. You can find our solar controller manufacturer! There is everything.

1. Adjustment steps. Press the button for more than 3s and the digital tube starts to flash, the system enters the adjustment mode, release the button, every time you press the key, the digital tube number will change to a number, until the digital tube displays the number against the number corresponding to the mode selected by the user from the table, and wait for the digital tube to stop flashing or press the button again for more than 3s to complete the setting.

2. Pure electric mode. In the absence of sunlight, the light intensity, in accordance with the set parameters to start the controller delay the start signal after 10 minutes of open load, the load begins to work; After 10 minutes, when the sun rises the controller starts the delay light intensity blocking, the blockade acknowledges the signal output, and the load containment works.

3. Optical fiber + control mode. The guidance process is the same as that of pure electric, the work is set at a time, when the load is automatically blocked, set at a time of 1-14 hours.

4. Manual mode. In this mode, the user can control the load with the button of opening and blocking, regardless of day or night. This mode is used in some special load environments or debugging.

5. Debugging mode. It is used for system debugging, the correctness of the system installation has been checked, when the optical signal blocks the load, the optical signal load is open, and the installation and debugging are convenient.

6. Normally open mode. It takes 24 hours to maintain the output state of the electrical load, and this mode is suitable for the power supply load.

The solar street light controller is a device used to control the work of the solar street light, which can automatically adjust the brightness and switching time of the street light according to the light intensity. Debugging the controller is a very important step when installing a solar street light, and the commissioning process of the solar street light controller will be introduced below.

First of all, you need to check whether the wiring of the solar street light controller is correct. Make sure that the connection between the controller and the solar panels, street light poles, and batteries is correct. If the wiring is incorrect, it may cause the controller to not work properly.

Next, you need to adjust the parameters of the solar street light controller. The solar street light controller often has multiple parameters, such as brightness threshold, delay time, etc. According to the actual situation, adjusting these parameters can make the street lights work more intelligently under different lighting conditions.

For example, the brightness threshold can be adjusted based on the output voltage of the solar panel to ensure that the street lights work properly at night.

During the commissioning process, it is also necessary to pay attention to observe the working status of the solar street lights. You can judge whether the controller is working properly by observing the brightness of the street light and the switching time. If the street light does not turn on properly at night or the brightness is unstable, it may be that the parameters of the controller are not set correctly or the controller itself is faulty.

In addition, commissioning can also be carried out by manually controlling the solar street light controller. By manually controlling the switch, you can observe the brightness change of the street lamp, as well as the speed at which the controller responds to the light intensity. If the manual control is not working properly, it is possible that the controller itself is faulty and needs to be repaired or replaced.

Finally, after the commissioning is completed, the solar street light controller needs to be tested. By simulating different lighting conditions, the working state of the street lamp can be observed to ensure that the controller can work normally in different environments.

In a word, the debugging of the solar street light controller is an important step to ensure the normal operation of the solar street light. By wiring correctly, adjusting parameters, observing the operating status and performing tests, it is ensured that the controller can intelligently control the brightness and switching time of the street lights according to the light intensity.
