Photocoupler

The traditional indoor lighting control is a simple control mode of the wall switch, which is completely controlled by people. Because of the lack of energy-saving awareness of the personnel entering the room, all the lights are turned on at will, resulting in waste of energy. The device is analyzed and processed by the intelligent processor to determine whether the light switch power supply is finally turned on or not, effectively avoiding the occurrence of power-on and bright inside the actual classroom. This design is mainly to complete the automatic adjustment function of indoor lighting. The light intensity is collected by the photoresistor, and the corresponding analog signal quantity is obtained by the characteristics of the photoresistor. The MSC51 single-chip microcomputer and the MSC51 single-chip microcomputer process the corresponding signals after receiving the signal, giving the control signal and controlling the relay to be connected. Whether or not to achieve intelligent control of the light. This design achieves the purpose of energy saving by reasonably controlling the number of lamps under the mediation of effective illumination intensity.

Solve the problem of electric energy waste in indoor public lighting. The light intensity signal is collected by the photoresistor, and the digital signal is converted to the single chip analysis and judgment processing, and then the relay controls the lighting and lighting circuit to finally determine whether the lighting power is turned on or off, thereby saving energy. In terms of innovation, the photoresistor is integrated with the single-chip microcomputer to control the indoor light, change the traditional control mode, and reasonably control the number of lights. The key points are the acquisition of the signal and the MCS-51 logic decision. The device is analyzed by an intelligent processor to give a control signal, which is different from the traditional lighting control mode. The traditional indoor lighting control is a simple control mode of the wall switch, which is completely controlled by people. Because of the lack of energy-saving awareness of the personnel entering the room, all the lights are turned on at will, resulting in waste of energy. In addition, a real-time light intensity signal is acquired by using a photoresistor to obtain real-time light intensity. The user of the device only needs to turn on the power according to the usual habits. Finally, whether the power of the lamp can be turned on depends on the control signal given by the intelligent processor, and the whole process is automatically completed by the intelligent controller. The three biggest advantages 1, energy saving 2, low cost 3, automatic completion of the adjustment of the intensity of the lamp line This device is suitable for indoor lighting environment similar to the school classroom. At present, the lighting control of the classroom is completely determined by the human mind, resulting in a serious waste of electrical energy. Due to the low cost of the equipment, the connection and transformation of the line is simple, easy to promote and apply, and the economic benefits are considerable.
