To satisfy the demand of Hulun Lake watershed environmental big data collection, and to solve the incompatible problem of different manufacturers protocols, a data acquisition gateway was designed based on the Constrained Application Protocol （CoAP）. This study discussed the basic principle and implementation method of CoAP in detail and gave the overall design, the hardware and the software design of each part. Furtherly, the study gave the detail design of hardware which is based on the STM32 microprocessor and software design which is based on the open-source operating system RT-Thread. The experimental result shows that, the design is feasible and it has the characteristics of high transmission efficiency and better compatibility.
