Information Acquisition Structure of Internet of Things Based on Intelligent Gateway between ZigBee and Ethernet

As a short-range wireless communication protocol technology, ZigBee has been widely used in industry, agriculture and other fields. An efficient gateway for IoT (Internet of things)between ZigBee and Ethernet based on STM32 is proposed in this paper. The system hardware was composed of STM32F407, ZigBee coordinator and acquisition module. The system software is established under uVersion Keil5 environment and the user interface is built by C and HTML, which realizes the data visualization based on Ethernet port and serial port. In order to capture relevant data from acquisition module, the reliable data access processing and protocol analysis should be completed. This intelligent gateway effectively established the communication between the network port and serial port, and the Internet of Things construction is realized.
