Abstract: In order to solve the test data transmission problem in the home appliance testing room, the scheme of remote monitoring of home appliance test parameters is designed. In this design, the test data of the EUT is collected by the wireless module and reported to the cloud via the NB-IoT network. Users can monitor the test data and running status of EUT through the web interface anytime, anywhere. NB-IoT network has the characteristics of wide coverage, low power consumption, low cost, large connection, low data rate, etc., which is very suitable for laboratories with strong shielding, good sealing and inconvenient network routing. The application data processing service in the cloud is provided by Zen Cloud IoT Platform, an industrial public cloud service platform in the field of smart appliances. The designed scheme has been verified by actual application and can realize the function set previously.

Key words: NB-IoT, Remote data monitoring, Zen cloud IoT Platform
