Temperature-self-adaptation greenhouse illumination intelligent control system and control method

The invention relates to a temperature-self-adaptation greenhouse illumination intelligent control system and a control method thereof. The system comprises an upper computer, a main control terminal, a Zigbee host node, n Zigbee light supplement control nodes, a Zigbee sunshade control node and n Zigbee monitoring nodes. The upper computer is in communication with the main control terminal through a network. The Zigbee light supplement control nodes are connected with a PWM driving module. The output end of the PWM driving module is connected with a light supplement lamp. The Zigbee monitoring nodes are connected with a single preprocessing circuit which is connected with an illumination sensor and a temperature sensor. The Zigbee sunshade control node controls a sunshade roller shutter machine to work through the driving module. The temperature-self-adaptation greenhouse illumination intelligent control system and the control method are based on the optimal output-investment ratio, and intelligent and accurate control over a greenhouse illumination environment is achieved.
