This paper designs an intelligent kitchen lampblack machine control system based on Alibaba IOT Cloud Platform,which can control the lampblack machine by accessing Alibaba IOT Cloud Platform through home WiFi. The intermediate device,which connects Alibaba IOT Cloud Platform with the lampblack machine, is developed by IOT embedded modules using WM-NBM-09A chip and STM32F100BV chip as the core. The communication channel is established with the wireless router. The lampblack machine instructions of on-off, wind speed, status and height are controlled by the monitoring data of the main control panel.Test result shows that the control system based on Alibaba IOT Cloud Platform is outstanding in automation, sensitivity and cooking fume purification handling.
