Design Of Greenhouse Data Acquisition System Based On ZigBee Wireless Sensor Network

China is the largest developing country in the world and has made great progress in many areas.With the continuous development of China's economy and science and technology,the era of intelligence and information technology is getting closer and closer to us.At the same time,China is also a large agricultural country with a large population.How to obtain real-time and accurate crop growth information and improve crop production efficiency more efficiently has become a hot topic in China's agricultural development.Modern information technology is unimpeded and developed,providing excellent channels for agricultural development.In order to promote agricultural output value,we must accelerate the pace of agricultural informatization and combine agricultural production with information technology.From the perspective of agricultural economy,the production of agricultural greenhouses is mainly to provide people with fruits and vegetables against the season,greatly promoting the economic development.However,agricultural greenhouses have high requirements for the growth environment of crops.In order to obtain more accurate growth environment information of crops,we apply the wireless sensor network to the work of greenhouses data collection.Based on the wireless sensor network and ZigBee technology as the main means of implementation,this paper constructs a set of intelligent and efficient greenhouse data monitoring system.This system can monitor the crop growth information in the greenhouse in real time,accurately and efficiently,which greatly reduces the manpower input and power consumption.Based on practical problems,this paper built a ZigBee wireless sensor network-based greenhouse data acquisition system.It studied the problems of power consumption optimization,stability and data acquisition algorithm processing of the system one by one and based on technical solutions.First of all,the stability of the system is the key and the first major problem to be solved,because it is the first premise to ensure the safe and stable operation of the whole system.This topic is solved from the perspective of hardware from the two parts of the system power supply stability and communication stability.Secondly,the power consumption of the system is solved from two aspects: hardware timer setting sleep time and software algorithmprocessing data to reduce power consumption.Last,this topic research important part of the sensor nodes to the system data collected by kalman filtering algorithm for processing,after using a particle filter to optimize the PID controller algorithm to optimize data processing error,further improve the precision of the collected data,after processing,the data is accurate and correct at the same time,almost all the noise and interference is eliminated,effectively reduce the data transmission to the system,the loss of system channel is unimpeded to ensure the stability of the data and information transmission(ZigBee communication stability).After the optimization system of low power consumption,good stability and high degree of automation,to built a kind of crops in greenhouse intelligent and efficient,real-time accurate growth environment,agricultural workers can be controlled by PC terminal and mobile terminal for real-time monitoring of crop growth status and through the various parameters of the corresponding control equipment to implement the accurate adjustment,precision agriculture in our country,the intelligent was preliminarily realized.Figure [74] Reference [65] chart [10]...
