摘要
本文基于Mina设计并实现了物联网通信中间件系统,对物联网应用平台发过来的控制指令进行解析包装,统一发送给不同的控制设备;同时,接收物联网终端数据,对海量的传感数据进行预处理,最后通过统一接口将数据传输到物联网应用平台.本文依据物联网传感器的数据特点设计了标准数据传输协议,并使用Cumulative Protocol Decoder类高效地处理了Mina的断包、粘包问题,实现了高性能的消息并发处理和可靠的异步数据传输,使数据的传输和处理更加高效,提高了整个物联网系统的通信效率.
The IoT communication middleware system was designed and implemented based on Mina in this paper. The control commands sent by the IoT application platform was analyzed and wraped. And then it will be sent to different control devices. The massive sensing data sent form the IoT terminal is received and preprocessing meantime. Finally,the sensing data will be transfered to the IoT application platform through a unified interface. A standard data transmission protocol was designed based on the data characteristics of the IoT sensor,and the CumulativeProtocolDecoder class is used to efficiently handle Mina's packet break and sticky packets in this paper. High-performance message concurrency processing and reliable asynchronous data transmission has been implemented. The data transmission and processing got more efficient,and the communication efficiency of the entire IoT system has been improved.
