Design and fabrication of street light controllers 50

A street light controller is a device used to control street lights, which is able to automatically adjust the brightness and switch of street lights according to the situation when it is dark and bright. The following will introduce the design and production of street light controllers.

First of all, the design of the street light controller needs to consider the following aspects:

1.Photosensitive elements: Street light controllers need to use photosensitive elements to sense the brightness of the surrounding environment. Commonly used photosensitive elements include photoresistors, photodiodes, etc. Based on the output signal of the photosensitive element, it is possible to determine the situation when it is dark and bright.

2.Control circuit: The control circuit is the core part of the street lamp controller, which can control the brightness and switch of the street lamp according to the output signal of the photosensitive element. The control circuit can be implemented using a microcontroller or a logic gate circuit.

3.Power circuit: The street light controller needs a stable power supply to supply power. You can choose to use AC power supply or DC power supply, and choose the appropriate power supply circuit according to the actual situation.

4.Output interface: The street light controller needs to have an output interface to connect to the street light. You can choose to use relays or transistors to control the switch of the street light, and you also need to consider the brightness adjustment interface of the street light.

When making a street light controller, you can follow the steps below:

1.Select the appropriate photosensitive element and connect it to the control circuit. According to the output signal of the photosensitive element, the working state of the control circuit is adjusted.

2.Design a control circuit to control the brightness and switching of street lights according to the output signal of the photosensitive element. This can be achieved using either a microcontroller or a logic gate.

3.Design the power supply circuit and choose the right power supply circuit to supply power. Choose AC power supply or DC power supply according to the actual situation.

4.Design the output interface and choose the appropriate relay or transistor to control the switch of the street light. At the same time, it is also necessary to consider the brightness adjustment interface of the street lamp.

5.Layout and soldering of circuits are carried out to connect the individual components according to the design.

6.Debugging and testing of the circuit to ensure that the street light controller can work properly.

7.Install the street light controller in a suitable location and connect it to the street light.

Through the above steps, you can complete the design and production of the street light controller. The street light controller can automatically adjust the brightness and switch of the street light according to the dark and bright situation, improving the energy efficiency and service life of the street light, and also saving energy.

The design and production of the street lamp controller is an original copy When will it be delivered?

The principle of street lamp controller: the street lamp controller integrates electromagnetic technology, intelligent control technology and data control technology, and intelligently adjusts it in a controllable and gentle way, so that the output voltage is stable between the set rated value range, and the street lamp controller realizes the ideal combination of the working current and brightness requirements of the public lighting system, so as to achieve the purpose of saving electricity and optimizing power supply, and the rate of the street lamp controller can be as high as 20%-40%, and the protection of the power system can extend its life by 3-4 times. The street lamp controller mainly uses imported components, and rarely uses active components, through the perfect quality control in the production process, to ensure a very high product safety, so as to ensure that the user unit to provide more safe, reliable and better performance of the product service.

The type of street lamp controller, there are two types of street lamp controller, indoor type: installed at the lower end of the indoor lighting control cabinet; Outdoor type: It can be installed according to user requirements, placed in a stainless steel cabinet, and the protection level is IP54.

At present, the brands of domestic street lamp controller production are: lamp network street lamp controller, street lamp remote controller, lamp network street lamp centralized power saver, intelligent street lamp special power saver; special energy-saving control cabinet for street lamps; Street lamp astronomical controller, astronomical clock, celestial clock, intelligent street lamp energy-saving control cabinet, street lamp power-saving control cabinet, street lamp power-saving and a series of street lamp controllers; And through the testing and certification of the National Quality Inspection Center, in line with the national electricity requirements. ET2, KQ-LD1 intelligent street lamp controller adopts the most advanced computer control technology abroad, uses the operation law of the sun and the earth and the relationship between the longitude and latitude of the earth and sunrise and sunset, and calculates the sunrise and sunset time according to the law of change of the four seasons and the longitude and latitude algorithm.

This product has the function of fine-tuning the switching time and midnight control, so as to adapt to the needs of different geographical environments; It is the best time controller for street lights, neon lights, advertising light boxes, monitoring and other equipment, which can effectively save resource consumption and reduce waste.

It's very simple, just use the street lamp clock control of Dandong San'an Company to control it.

The working principle is: use the AC contactor to control the switch of the main power supply phase line of the street lamp, and use the bell control to control the suction and disconnection of the AC contactor.

The specific operation process is as follows:

1. Separate a live wire from the power supply to access the fire inlet terminal of the clock controller, and the clock controller generally has two or three fire wire terminals connected to the corresponding AC contactor, and the neutral line is shared.

2. Set the time and latitude and longitude of the clock control.

3. Set the power transmission time and power off time of each fire terminal of the clock control. In general, the power transmission time of each fire terminal is always the same, and the power failure time is different.

Working method: When the power transmission time is reached, the clock control begins to send power to the AC contactor, and after the AC contactor is energized, the main power supply phase line of the street lamp is connected and the light is on.

When the power-off time of a certain road fire of the clock controller is reached, the road is out of fire and the power is off, the corresponding AC contactor is disconnected, and the phase line of the street lamp corresponding to the AC contactor is de-energized, and the lamp is extinguished.

I want to use a solution to make the street lights automatically turn on all at a certain time period I set, and only light up a certain phase line at a certain time period. The cost is not too high, please know the guidance.
