Research On Agricultural Products Cold Chain Logistics Monitoring System Based On Internet Of Things

With the improvement of people's living standard,the quality of agricultural products has become an increasingly concerned living problem in recent years.How to ensure the freshness and quality of agricultural products in the process of logistics transportation is related to the quality of people's life and the development of agricultural economy.At present,there are some problems in the monitoring process of agricultural products cold chain logistics transportation environment,such as low informatization degree of monitoring process,unscientific monitoring,single monitoring project,and partial monitoring area.Aiming at the problems existing in the monitoring process of the cold chain logistics of agricultural products mentioned above,this paper proposes a monitoring system and solution for the cold chain logistics of agricultural products based on the Internet of things,which is used to realize scientific and information monitoring of the cold chain logistics of agricultural products and improve the quality of agricultural products in the cold chain logistics process.This paper firstly analyzes the current situation and problems of cold chain logistics of agricultural products and the research status at home and abroad.According to the current situation,existing problems and research trends,the overall design scheme of monitoring system of cold chain logistics of agricultural products based on Internet of things is developed.According to the design scheme,this paper analyzes and designs the agricultural products cold chain logistics information collection system,agricultural products cold chain logistics vehicle-mounted monitoring platform,and agricultural products cold chain logistics monitoring system.Combining with the actual situation of cold chain logistics of agricultural products,this paper uses wireless sensor network technology to design the agricultural products cold chain logistics information collection system,and constructs a wireless sensor network for cold chain logistics of agricultural products.Embedded technology is used to design the on-board monitoring platform of cold chain logistics of agricultural products,which is used for the staff of cold chain logistics of agricultural products to observe the compartment environment and give warning.Use desktop applications under the Windows operating system development and design technology,GIS geographic information system in the Baidu map API technology,database programming and management technology to design of agricultural products cold chain logistics monitoring system,remote monitoring of agricultural products cold chain logistics realize computer terminals,vehicle location positioning,and data query view,etc.Finally,this paper carries out tests and experiments on the agricultural products cold chain logistics monitoring system based on the Internet of things to improve the deficiencies and improve the system.In this paper,design of agricultural products cold chain logistics monitoring system based on Internet of things in the experiment results show that the system can stable and highly efficient scientific and effective agricultural cold chain logistics process of collecting data and monitoring work,convenient staff management of the agricultural products cold chain logistics process,improve the freshness in the process of cold chain logistics of agricultural products and quality,achieve expected experimental goal.
