Wireless Photovoltaic LED Landscape Light Group Control Method Based on Multi-Rule Weighting

To realize intelligent, efficient, and energy-saving control of landscape light groups, a wireless photovoltaic light emitting diode (LED) landscape light group control method based on multi-rule weighting is proposed. Sensors are used to collect environmental data of each photovoltaic LED landscape light and transmit it to the microcontroller through the Zigbee wireless communication network. The microcontroller generates a group control scene lighting rule library based on the lighting elements of each landscape light to determine the actual illumination and expected illumination of each photovoltaic LED landscape light. The illumination error is used as the input of the multi-rule weighted fuzzy proportional-integral-derivative (PID) method. The fuzzy controller sets the variable weight membership as the control criterion, and the fuzzy reasoning rules of the landscape light group control are weighted and input into the PID controller. According to the output of the PID controller, the dimming circuit of the landscape light is controlled, and the output power of each landscape light is dynamically adjusted to realize the control of the wireless photovoltaic LED landscape light group. The experimental results show that the brightness of the landscape light changes significantly when the wireless photovoltaic LED landscape light group is controlled by this method, and the energy saving rate of the landscape light energy consumption under different lighting scenes is higher than 50 %.
