Abstract
A low-power, long-range chain buoy monitoring network based on LoRa technology is designed for marine environment monitoring with characteristics of continuity and wide area. Firstly, the overall architecture of the marine environment monitoring network is constructed, two communication mechanisms are designed, namely timed reporting and downlink control, and are designed from both hardware and software perspectives. By analyzing the different parameters of LoRa, the best compromise was determined in terms of communication distance, power consumption and number of network nodes. Experiments show that the transmission performance of the buoy network is reliable and stable in LoRa chain networking mode, the transmitting current of a single node in networking state is less than 150mA, the packet loss rate is less than 1% in normal mode, and the distance between nodes can reach 1000m, which can meet the functional requirements of marine monitoring buoys.
