Fuzzy control-based solar intelligent lighting system and control method thereof

The invention provides a fuzzy control-based solar intelligent lighting system and a control method thereof. The lighting system comprises the steps as follows: (1) a power supply system has the characteristic of adaptive switching control, namely the system can select a lead storage battery for supplying electricity to an LED lighting lamp array according to the voltage or current condition of the lead storage battery in a power supply circuit; when the lead storage battery does not meet a power supply voltage, a network supply system is automatically selected to supply electricity; and (2) the LED lighting lamp array has the characteristic of fuzzy control, namely the system can control the number of LED lighting lamps, which are turned on, of the LED lighting lamp array according to the indoor actual brightness. According to the control method of the lighting system provided by the invention, according to comparison of brightness requirement parameters corresponding to a gear selected by a user and actual brightness parameters, a controller carries out calculation processing on these data and sends out a command to the LED lighting lamp array according to the calculation result; and adaptive adjustment for a lighting device is achieved by a fuzzy control rule on the lighting device.
