Abstract:Based on the STM32 processor, a general gateway with the self-configuration function is designed, which can realize data communication and conversion of different protocol interfaces between the sensor network layer and the server in data center. Firstly, the gateway collects energy consumption data in target building through RS485 field bus. And then, stores the data into SD card in the form of XML format. Finally, it transmits the data to server by TCP protocol. The results of practical project reveal that the gateway is reliable and steady, and meets the requirements of the data acquirement and data transmission of internet of building energy system.
