Design of Multi-network Data Acquisition System Based on Cloud Platform

This paper describes the construction of the multi-network data acquisition system monitored by cloud platform. The system takes STM32F4 as the system control core platform. In the Intranet mode, data collection is carried out through a variety of network methods, including ZigBee network, Nrf24L01 radio frequency network, bluetooth network, etc. The data collected by each network is received and sent to the core platform through the receiving end. After the data is processed by STM32F4, all data are uniformly sent from the WIFI module to the cloud for data storage. Users can monitor the data through mobile phones and PCS. In multi-network data networking, sensor nodes are more flexible in addition and deletion, the network layout can be adapted to local conditions according to actual needs, and the external output of data is all achieved through the TCP/IP protocol to achieve the integration of multiple networks. Through the actual measurement, the data monitoring through cloud platform is realized, with high real-time data update and stable transmission.
