针对地质灾害监测传感器的采集数据具有数据波动变化慢的特点,提出了基于增量数据传输的通信协议。前端监测点仅在各传感器的数据发生变化时,向监测管理中心传输数据变化量,从而实现单个用户机负载更多传感器的数据通信。最后,详细设计了该协议框架下的通信帧结构和类型,以及各类帧的交互方式。 For the data collected by geological disaster monitoring sensors, the data fluctuates slowly, and a communication protocol based on incremental data transmission is proposed. The front-end monitoring point transmits the data variation to the monitoring management center only when the data of each sensor changes, so as to realize the data communication of more sensors loaded by a single user machine. Finally, the structure and type of communication frame under the framework of the protocol are designed in detail, and the interaction modes of various frames are designed.
