Design And Implementation Of Smart Ranch Monitoring Platform Based On LoRa Technology

China is a large animal husbandry country,and the proportion of animal husbandry is rising.As the main "battlefield" of animal husbandry,the development of animal husbandry must pay attention to the modernization of animal husbandry.In this article,taking dairy farm as an example,Adoption Wireless communications Technology combined with modern pasture management,To realize the comprehensive development of intelligent technology in pasture,improve the fine breeding environment of pasture.According to the development of intelligent pasture and wireless communication technology at home and abroad,thisarticle points out the deficiency of existing pasture monitoring,and puts forward the overall scheme of intelligent pasture monitoring platform based on LoRa technology.The program should realize the functional requirements of behavior identification,estrus monitoring,environment monitoring and identification of cows in pasture.First of all,an improved K-means algorithm based on KNN algorithm is determined to realize the cow’s behavior recognition by demand analysis,and the cow’s oestrus behavior monitoring is realized by Fast clustering algorithm of subsequence segment based on structure similarity.And further determine the wireless transmission module with SX1278 as the core to realize data transmission and networking functions.At the same time,EM4305 is used as the core to design a set of cow identification module based on RFID,which can accurately collect the basic information of cow.Data acquisition is accomplished by using SHT10、MPU6050 sensors,And through the design of the corresponding data acquisition and LoRa data transmission programs,the function of system information transmission is completed.Finally,combining with the hardware design and the recognition algorithm,the upper computer "intelligent pasture monitoring platform management system" based on C/S(client/server)architecture is developed.Through the combination of software and hardware and the design of recognition algorithm,the intelligent ranch monitoring platform realizes the modernization of ranch construction and improves the information level of breeding environment.This platform has got rid of the shortcomings of the traditional pasture,such as low efficiency,less monitoring function,complex operating environment and so on.It has a bright future.
