【摘 要】我国从2009年“感知中国”行动启动以来,物联网产业得到飞速发展,大量物联网新技术、新产品应用到各行各业。物联网软网关作为将传统和下一代设备引入物联网的关键要素,把分散在不同位置、不同应用感知设备通过网络连接在一起,实现不同制造商设备间的通信。论文分析了实现物联网软网关接入的主要技术、业务场景,旨在研究一种能同时支持不同感知设备、多种接入协议,具备高并发、高可用能力的通用物联网软网关的实现方法。
【Abstract】Since China launched the action of "Experience China" in 2009, the internet of things industry has developed rapidly, and a large number of new technologies and products of the internet of things have been applied to all walks of life. As the key element of introducing traditional and next-generation devices into the internet of things, internet of things soft gateway connects devices scattered in different locations and with different application sensing through the network to realize the communication between devices of different manufacturers. This paper analyzes the main technologies and business scenarios for realizing the access of the internet of things soft gateway, aiming to study a realization method of general internet of things soft gateway which can support different sensing devices and multiple access protocols at the same time, and has high concurrency and high availability capabilities.

1 引言
互联网技术实际是物联网技术的基础,而物联网是基于互联网技术发展和延伸出的一种新技术,物联网是将标准工业设备、射频识别(RFID)、激光扫描器、红外感应器、摄像头、全球定位系统等信息传感设备,按约定协议进行通信,以实现智能识别、数据采集、定位、跟踪、监控和管理的一种网络技术。而构建物联网的核心就是物联网软网关,就像驾车经过停车场出入口道闸,一个网络与另一个网络通信,也必须经过一个关口,这个关口就是网关,网关又称协定转换器或网间连接器,按特定需求设计的网关大多仅作为网络协议的转换器,在应用需求变动时需对网关做很大的变动才能适应新的应用场景,这使得物联网大规模应用困难重重。鉴于此,本文提出了一种物联网软网关实现思路,具有一定的通用性与适应性。……
