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, MSP430 FR5 x 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.
