Design Of Intelligent Monitoring System For Greenhouse Based On CC1101

Greenhouse planting is suitable for such areas as growing seedlings, anti-season vegetables planting and flower culture, etc. But traditional greenhouse planting technology is so backward and inefficient that it can not meet the needs for the development of the modern agriculture. Due to the shortage of many environment parameters in greenhouse for fanners, it is very common for the production of the crops to decrease. By using an efficient and reliable monitoring system, the agricultural production efficiency can be improved and the risks can be reduced.Wireless data transmission based intelligent control system not only breaks through many limits of the wired data transmission system caused by environmental factors, but also reflects the real-time spot transmission message precisely. It has simple system architecture and can network the system at anytime according to the spot environment.In order to improve the efficiency of the agricultural production and increase profits, we design an intelligent greenhouse climate monitoring system based on radio frequency communication. This system uses technologies in computer, micro controller, sensor and radio frequency to collect spot data; meanwhile, the upper computer also stores and prints the message. Intelligent monitoring system based on radio frequency communication can be applied to the regulations of the modern greenhouses to maintain the greenhouse climate in the state which is best for the growth of vegetables to improve the efficiency and production. The system uses level3topological structure and is composed of sensor tag, node control circuit, host control circuit and upper computer. The sensor tag is temperature sensor DS18B20, all the sensor tags are distributed evenly in the greenhouse. The sensor tag can deliver the monitored real-time temperature message to the node control circuit. The node control circuit uses MSP430F149to process the received message and deliver it to the host control circuit by the wireless module CC1101, and then compares the spot temperature with the threshold value to monitor and adjust the greenhouse. In this paper, we put forward some measures to optimize the system. By monitoring some environmental factors like temperature, humidity, illumination intensity and the density of CO2, we can improve the production efficiency, greatly reduce labor intensity, and increase the economy profit for the farmers, so the system has a broad perspective.Modern wireless technology is mainly used in two areas, wireless short range network and wireless local area network. The advantage for the usage of the intelligent wireless data collecting system in greenhouses can be embodied in its low power consumption and high precision. In this paper, we put forward some optimizing measures in the premise of realizing the functions of the wireless communication system to broaden the perspective of the system. By investigating the vegetable planting canopy in rural areas, we conclude the current situation and future of the intelligent vegetable canopy in rural areas. Modern intelligent greenhouse planting canopy can cultivate the environment best the growth for the crops. The messages to be detected are temperature, humidity, illumination intensity and the density of CO2, etc. Manual data collecting by fuel thermometer is a waste of time and energy, and can not boost the informatization, and is not good for the large scale planting for farmers. So the popularization of the intelligent vegetable canopy not only improves the production efficiency, greatly reduces labor intensity, increases the economy profit for the fanners, but also conforms to the policy from the Party Central Committee which is to promote agriculture by applying scientific and technological advances.
