摘要
物联网将会是未来很长一段时间内 IT 产业的发展趋势,数字整合的需求日
益增长,对作为感知层核心组成元素的传感器的开放性和互操作性提出了越来越
高的要求。本文就传感器接口标准化所将涉及的关键技术问题进行了比较深入的
探讨,主要内容如下:
1)调研分析了物联网发展战略及现有的传感器接口/网络的标准体系,明确传感
器接口标准化体系设计的目标,在此基础上提出了传感器接口标准化设计的总体
模型;
2)基于软硬分离的模块化原则,将传感器接口标准分解为信号接口与数据接口。
信号接口以传感器的输出信号类型为分类依据,对传感器的输出信号及其接线方
式等做出规范说明;数据接口分为两方面,一个是传感器节点的数据描述,比如
模拟输出传感器接入相应的标准化接口模块构成一个传感器节点,另一个是传感
器的数据描述,对数据接口进行了建模并给出了部分模板;
3)基于信号接口标准给出了标准化接口模块的硬件设计,并实际设计实现了电
流型、电压型以及数字IO 型模块,给出了相应的硬件选型以及电路设计与实现;
进行了标准化接口模块的软件设计,说明了详细的固件代码设计。除传统串口外,
提供以太网接口,嵌入 UDP 协议,提供后期开发的便利接口;
4)初步探讨了标准体系的应用场景,从底层硬件到上层开发平台。

Abstract
The of things will be the trend of IT industry development
trends in the long term. Growing demand for digital convergence asks for
higer requirements for the openness and interoperability of sensors,
which is the core element of perception level. The thesis will discuss
the key issues of standardization of the sensor interface, which involves
the following aspects:
1) The thesis analyzes the development strategy and the standard system
of the existing sensor interface / network standards, specify the design
goals of sensor interface standardization system, put forward the overall
design of sensor interface standard model on this basis;
2) Based on the principle of hard and soft modular separation, the sensor
interface standard is divided into signal interface and data interface.
The signal interface uses the sensor's output signal as the classification
basis and gives a regulated statement for the output signal of sensor and
its wiring;the data interface is divided into two aspects, one is the
description of the data of sensor nodes, such as access to the
corresponding analog output sensors from the standardized interface
module, the other is the description of sensor data, gives
