Research On Pasture Grazing System Based On Digital Twin Technology

In recent years,the main problem facing the economic development of animal husbandry and the stability of grassland ecosystem is that grassland resources have been greatly degraded due to long-term overgrazing.At present,most of the monitoring and research work on grassland grazing only focus on simple location services such as displaying the real-time location of grazing herds and querying the previous grazing records.Obviously,this can not meet the development of modern animal husbandry.Modern animal husbandry requires comprehensive grassland ecological health,and then real-time,scientific and effective intelligent monitoring of grazing.As a new technology,digital twin technology can realize the interactive fusion between data.this paper innovatively combines digital twin technology with grassland grazing monitoring,studies and designs a grassland grazing monitoring system with digital twin as the core technology,and verifies the feasibility of the system through experiments.Firstly,combined with the digital twin concept and grassland grazing related theories,this paper designs the overall scheme of grassland grazing monitoring system based on digital twin technology.Then,according to the overall scheme,the data interaction between physical grassland and twin grassland is designed and studied,and the information interaction between physical grassland and digital grassland is realized;Then the virtual reality technology is used to carry out three-dimensional visual modeling of grassland grazing scene,and a twin grassland is constructed,which can not only form a mapping relationship with the physical grassland,but also has good visual effect,and supports the function of human-computer interaction.Then,for grassland grazing path planning,a grazing path planning mechanism based on digital twin technology is proposed,and the grassland twin map model is established based on the grid method.At the same time,through the optimization and simulation test of the traditional A* algorithm,it is proved that the performance of the optimized A* algorithm has been greatly improved,the planned path turning points are reduced,and can well meet the actual needs of grassland grazing path real-time planning.In order to verify the feasibility of this model and grazing path planning method,using Unity3 D virtual reality technology and taking MAODENG pasture in Xilinhot City,Xilin Gol League,Inner Mongolia as the experimental point,this paper develops a grassland grazing monitoring system based on digital twin technology,and realizes the comprehensive intelligent monitoring of the whole grassland grazing process by demonstrating the function of the system.The grassland grazing system based on digital twin technology studied in this paper combines remote sensing,wireless data transmission and other technologies.By constructing twin grassland in virtual space,grassland grazing monitoring will not be limited by objective conditions such as space,time and climate.By objectively making scientific and efficient grazing path planning decisions for grassland grazing,it can effectively improve the technical ability and management level of grassland staff,It is of great significance in helping herdsmen make rational and effective use of grassland for grazing and protecting grassland ecology from damage.
