Research on Smart Household Appliance System Based on NB-IoT and Cloud Platform

In this paper, a smart household appliance system based on NB-IoT technology and OceanConnect cloud platform is designed. The system mainly takes BC-95 as NB-IoT module and MSP430 as MCU to build the hardware system, combined with OceanConnect cloud platform to implement smart household appliance verification system. The system can realize communication between NB-IoT device and cloud platform based on CoAP protocol: device collects data and reports it to the cloud platform, and the cloud platform sends commands to the device. The test results show that the verification system can realize the communication between NB-IoT device and cloud platform, satisfying design requirements.
