Relay control lighting intelligent lighting system circuit design

　Traditional indoor lighting control for the simple control of the wall switch mode, completely controlled by the people, because the awareness of energy saving into the room, all the lights are free to open, resulting in energy waste. The device through the intelligent processor analysis and then determine the light switch power * finally open or not, effectively avoiding the actual classroom power that is bright and the occurrence of the situation. The design is mainly to complete the indoor lighting automatic adjustment function. By the light-sensitive resistor for the collection of light intensity, and by the characteristics of photoresistors get the corresponding analog signal, MSC51 by SCM, SCM SCM after receiving the signal to make the appropriate treatment, given the control signal to control the relay connected Whether or not, in order to achieve the intelligent control of light. This design in ensuring the effective lighting intensity of the mediation, the reasonable control of the number of lamps, thus achieving the purpose of energy saving.

Solve the indoor public lighting waste of energy problems. Light-sensitive resistor from the collection of light intensity signal, the digital signal is converted to the single-chip analysis and judgment processing, and then by the relay control lighting circuit, * final decision light power on or not, thus saving power. Innovation, the photosensitive resistance of the indoor light sensitized integrated microcontroller control, change the traditional control mode, a reasonable control of the number of lights. The key point is the signal acquisition and MCS-51 logic decision part. The device is analyzed by the intelligent processor gives the control signal, different from the traditional lighting control mode. Traditional indoor lighting control for the simple control of the wall switch mode, completely controlled by the people, because the awareness of energy saving into the room, all the lights are free to open, resulting in energy waste. In addition, the use of photosensitive resistance for real-time light intensity signal acquisition, come to real-time light intensity. The user of the device only needs to turn on the power as usual. * Whether the power of the light can be turned on finally depends on the control signal given by the intelligent processor, and the whole process is automatically completed by the intelligent controller. * Big three advantages 1, energy-saving 2, low cost 3, automatically adjust the intensity of the light line This device is suitable for indoor lighting similar to the classroom classroom environment. At present classroom lighting control is entirely determined by the human mind, leading to a serious waste of energy. Due to the low cost of this equipment, simple wiring connection and transformation, easy to popularize and application, the economic benefits are considerable.
