摘　　要：针对设施温室环境数据采集及传输的特点,分别对现有数据存储技术及无线传输技术进行对比分析,最终采用FRAM存储和处理滞留数据,具有低功耗、长寿命、防篡改等特点;采用NB-IOT技术搭建远距离无线传输路径,以其强连接、高覆盖的特点提高数据与指令传输过程中的可靠性,与传统技术相比成本更低;同时设计了具有低功耗特性的MSP430FR5x芯片作为系统核心,采用C++ Builder和Mysql设计了服务器守护监听程序。经测试,系统能够有效适应农业智慧生产条件下低频率、小数据量的传输要求,有效降低功耗的同时确保了数据传输的连贯性。In view of the characteristics of environmental data collection and transmission for facility greenhouse,the author compared and analyzed the existing data storage technology and the wireless transmission technology,and finally adopted FRAM to store and process the retained data,because FRAM was characterized by low power consumption,long life and tamper-proof.NB-IOT technology was adopted to build long-distance wireless transmission path,which had the characteristics of strong connection,high coverage and lower cost,and could improve the reliability of data and instruction transmission process.At the same time,MSP430FR5x chip with low power consumption was designed as the core of the system.C++ Builder and Mysql were used to design the server daemon monitor program.Through testing,this system could effectively adapt to the transmission requirements of low frequency and small data amount under the conditions of agricultural intelligent production,and could effectively reduce the power consumption and ensure the consistency of data transmission.
