Abstract: In order to promote the modern management of greenhouse in North China, and to make the facility horticulture develop towards high yield and high efficiency, the intelligent control system was established based on ZigBee. To meet the needs of the control of agricultural greenhouse facilities, the system was produced by Jennic wireless microcontroller JN5139 as the control core, and the wireless sensor network was composed of sensor nodes and ZigBee wireless intelligent terminal. The system realized the real-time collection, monitoring, display, warning and control of the greenhouse environmental factors (including air temperature, humidity, light intensity, CO2 concentration and soil pH value), and could provide the historical data of greenhouse environmental factors. In order to make the results more accurate, the sensor data sequence was smoothed three times on the nodes, then the smoothed data was sent to the gateway, and the linear regression analysis of data were carried out. The system basically met the needs of wireless, intelligent and precise modern facilities horticulture. The results showed that the greenhouse intelligent control system had the characteristics of stable and simple operation, and the results were accurate, which could effectively improve the management efficiency of the solar greenhouse, and had a good application prospect.

Key words: solar greenhouse, intelligent control, ZigBee, environmental factor, JN5139, three exponential smoothing
