Abstract:

With the development of computer and biological sciences and information technology, the Internet of things (IOT) technology has been successfully applied to agricultural fields. Twenty-first Centuries is the times that science and technology are rapidly developed. The realization of agricultural modernization and integrated management is the urgently problem needed to be solved for modern agricultural technology. In this background, this paper puts forwards the key technology and existing problems of sunlight greenhouse complex system and intelligent IOT control system through the study of identified collecting and processing process of sunlight greenhouse temperature multi-nodes big system. The paper builds parameters mathematical model for the IOT bearing capacity from four aspects, such as, the occupied bandwidth, delay characteristics of the network, packet loss rate and power consumption, and uses MCU signal amplification system and a signal sensor to jointly control the temperature effect of sunlight greenhouse. Eventually, it finds that the occupied bandwidth of intelligent system has reached 35kb, the highest network delay has reached 20s, and the maximum of packet loss rate has reached 2.5%, which proves that the IOT characteristics of intelligent systems have more controlling complexity than that of the local system.
