A Network Adapter for Computing Process Node in Decentralized Building Automation System

Based on the STM32 processor, a network adapter is designed, which can realize data communication and protocol conversion between sensor and computing process node (CPN) in group intelligent projects. The adapter needs to be configured firstly, to know the communication parameters of the sensor and the corresponding storage location in the CPN. After that, the adapter begins to collect data, convert the message format, and send data to the CPN periodically. The results of practical project reveal that the proposed adapter is reliable and steady.
