Intelligent Lighting Energy Saving System Design

With the development of modern industry, people's demand for energy is increasing, and non-renewable energy is gradually being exhausted. However, in daily life, people's waste of electric energy is very serious. The lights cannot adjust the brightness by themselves when there is sufficient light in the room or corridor, and the power cannot be turned off by itself during the day or when there is no one there, resulting in serious waste of electric energy and further increasing the energy burden. Aiming at the shortcomings of the traditional lighting system, this paper designs a set of intelligent lighting energy-saving system that automatically adjusts the lighting brightness according to the light intensity of the room or corridor, and automatically cuts off the power during the day or when there is no one. To achieve the purpose of energy saving, it aims to provide people with more efficient and humanized practical needs.

1. Brief introduction of intelligent lighting energy saving system

(1) System components: The intelligent lighting energy-saving system is composed of a central control system and a peripheral execution system. The central control system uses an 8-bit single-chip microcomputer. This type of single-chip microcomputer has the advantages of strong stability, fast data processing speed, and relatively low price. suitable for application in this system. The peripheral execution system is composed of ADC0832 module, photosensitive sensor, pyroelectric infrared sensor, relay, new energy-saving lamp and so on. The two systems work closely together, and each module complements each other, so that it can better realize the function of intelligently adjusting the brightness of the light and switching it on and off in real time according to the light intensity of the surrounding environment and personnel information, reducing the waste of electric energy and reducing the energy burden.

2) ADC0832 module: ADC0832 module adopts 8-bit resolution, dual-channel A/D conversion chip, its input and output levels are compatible with TTL/CMOS, when using 5V power supply, the input voltage can be between 0~5V, It meets the voltage requirements of single-chip microcomputer and intelligent lighting energy-saving system. The chip conversion time of this module is only 32μs, and it has double data output function, which can be used as the data verification of this module, which can effectively reduce data errors. The module also has the characteristics of small size, fast conversion speed and strong stability, and is an important part of the intelligent lighting energy-saving system.

3) Photosensitive sensor: This system uses a sensitive photoresistive sensor. This sensor has the advantages of good waveform, strong driving ability, and high sensitivity to light. It is also equipped with an adjustable potentiometer to adjust the brightness of the detected light. When the ambient light brightness does not reach the set value, the DO terminal outputs a high level, and if it exceeds the set value, it outputs a low level, and the DO output terminal is directly connected to the single-chip microcomputer to detect the light brightness in real time through the single-chip microcomputer and drive the relay module to form a light-controlled switch that intelligently adjusts the brightness of the light in real time.

4) Human body infrared sensing module: The D-SUN PIR human body infrared sensing module used in this system has the characteristics of high sensitivity, strong reliability, ultra-low power consumption, and ultra-low voltage working mode. This module can automatically sense human body information. When a person enters the sensing range, it outputs a high level, and when the person leaves the sensing range, it automatically delays turning off the high level and outputs a low level, which is convenient for docking with various circuits. The flat signal is transmitted to the single-chip microcomputer, which can enable the single-chip microcomputer to implement intelligent detection of surrounding human body information. Photosensitive control can be set so that the module does not sense human body information during the day or when the light is strong, avoiding the waste of electric energy. It is the core component module of the peripheral execution system.

2. Working principle and performance analysis of intelligent lighting energy-saving system

The intelligent lighting energy-saving system is composed of 8-bit single-chip microcomputer as the main control system, and the peripheral system is composed of ADC0832 module, photosensitive sensor, D-SUN PIR human body infrared sensor module, relay, new energy-saving lamp and so on. There are photosensitive sensors and pyroelectric infrared sensors around the lamp base, which can detect the light of the surrounding environment and personnel information. The photosensitive sensors and pyroelectric infrared sensors transmit the signals to the single-chip microcomputer, which is processed by the single-chip microcomputer STC12C5A60S2 to realize real-time adjustment of light brightness and Opening and closing. When the indoor light becomes weak, it will cause the resistance of the photoresistor to increase. ADC0832 collects the analog signal and converts it into a digital signal, and transmits the signal to the STC12C5A60S2 control system of the single-chip microcomputer. Control the size of the output voltage to intelligently adjust the brightness of the light. In addition, the pyroelectric infrared sensor detects the infrared rays emitted by the human body in the room. When no signal is detected, the single-chip microcomputer judges that there is no one in the state, and the control relay automatically turns off the switch of the energy-saving lamp, thereby realizing the intelligent control of the switch on and off of the lamp. Moreover, this product can realize the function of self-locking when the power is off, so as to prevent the energy-saving lamps from being damaged by a sudden power call after a power outage.

This product can realize the intelligent control of lighting, realize low emission while saving energy, and meet the new requirements of today's society for green, energy-saving, and low-carbon life. It can realize automatic intelligent sensing of the information of the human body and the surrounding environment. When a person enters the sensing range, it outputs a high level, and when the person leaves the sensing range, it automatically turns off the high level with a delay and outputs a low level. Photosensitive control can be set so that the module does not sense human body information during the day or when the light is strong, which reduces the impact of the environment on the product.
