Design And Implementation Of Integrated Management And Control System For Facility Agriculture Based On Data Fusion

Facility agriculture is an important way to realize precision agriculture.Its basic principle is an intelligent agriculture mode to realize efficient production of animals and plants by adjusting and controlling the environmental parameters of animals and plants.It has the advantages of high intelligence,alleviating obstacles of soil continuous cropping,energy saving,water saving,fertilizer saving,accurately perceiving the information of animal and plant growth environment,and so on.It can reduce the human cost and improve the efficiency of agriculture.It is of positive significance to improve the production efficiency of animals and plants and ensure the supply of high-quality agricultural products.At present,the development level of facility agriculture industry in China is uneven,and has not yet formed a complete industrial chain.The lack of effective integration and distribution of existing facilities and technologies has led to the development of facility agriculture industry in China staying at a low level for a long time.In addition,the core equipment used to perceive and integrate the characteristics of animal and plant growth environment has long relied on imports,which has greatly restricted the sound development of facility agriculture industry in China.In this context,this paper proposes a multi-sensor data fusion-based information perception and fusion algorithm for plant and animal growth environment,and develops the corresponding management and control system.The integrated management and control system of facility agriculture based on multi-sensor data fusion is divided into upper computer subsystem and lower computer subsystem according to demand.Among them,the host computer subsystem,using SSH framework and SQL Server 2012 database,choosing workflow technology as the main technology,using multi-sensor data fusion technology and wireless sensor network technology,realizes the perception and fusion of environmental information of animal and plant growth,thus maximizing the efficiency of animal and plant growth.The test shows that the system has good interface friendliness.The lower computer subsystem uses STM32F103RBT6 as the main control chip,equipped with maintenance-free high-precision power supply module,wireless communication module,sensor cluster module of animal and plant growth environment information acquisition,and adopts multi-sensor data fusion algorithm to realize orderly storage and transmission of multi-type animal and plant growth environment information.In addition,the system has a human-computer interaction button module,which can realize the setting of system time,transmission cycle and other parameters,so that it can be more widely adapted to various facilities for agricultural applications.The system is tested in a certain area in East China.The experimental results show that the system works stably,has strong robustness,and the data transmission of multi-type sensors is orderly.It can effectively monitor and control the information of animal and plant growth environment in facility agriculture,and has positive significance for promoting the healthy development of facility agriculture in China.
