"Sensor Web中的快速传感器过程建模和注册"是一项针对Sensor Web领域的重要研究论文。Sensor Web是一种基于互联网的传感器网络系统，其核心任务之一是实现传感器的集中管理和信息共享。在这个背景下，论文的作者Xian'ge Xie、Xuefeng Liu、Jianhua Mao、Jingjing Fan和Fenxiao Ye来自上海大学通信与信息工程学院，他们提出了一个用户导向的快速传感器过程建模和注册方法。该方法首先深入分析了由Open Geospatial Consortium (OGC)制定的SensorML标准中的传感器描述概念模型。SensorML是一个用于描述和共享传感器信息的标准框架，它包含了识别（Identification）、能力（Capabilities）和联系（Contact）等关键元素。作者将描述传感器所需的所有信息划分为三个类别：必要元素、可选元素和每个类别内的元素格式，以便于标准化和简化操作。在这个模型中，所有同类别的信息被设计成统一的形式，降低了用户的输入负担。用户只需按照特定流程填写这些预设的表单，如传感器的标识符、测量功能、数据传输方式等，然后将这些表单提交给服务器。服务器接收到这些信息后，利用SensorML标准将其转化为XML格式，从而完成传感器的注册和模型构建。这个快速建模和注册方法的优势在于提高了效率，降低了用户学习和使用的复杂度，并且有助于Sensor Web平台更好地理解和管理大规模的传感器网络。通过标准化的过程，可以确保不同传感器之间的互操作性，促进信息的无缝集成和共享，进而推动Sensor Web技术在环境监测、物联网、智慧城市等领域的发展。这项研究对于优化Sensor Web的架构管理，提升数据处理和共享能力具有重要意义，为未来传感器网络的高效运营和应用提供了理论支持和技术路径。

Abstract—Sensor modeling and registration is the basis of

sensor centralized management and sensor information

sharing in Sensor Web. According to the SensorML standard

developed by OGC, this paper proposes a user-oriented fast

sensor process modeling and sensor registration method based

on the in-depth analysis of the SensorML conceptual model of

sensor description. With this method, all the information

required to describe the sensor will be divided into three

categories with defining the necessary elements, optional

elements and element format for each category: Identification,

Capabilities and Contact. Then the same category of

information will be presented in the same form. Users only

need to fill in these forms according to the process, and then

complete the sensor modeling process by submitting these

forms to the server. Finally, the server receives the

information to generate XML formatted sensor information

models of the SensorML standard. Users could complete the

sensor registration with these models. In order to verify the

feasibility of this method, this paper designs and realizes a fast

sensor modeling and sensor registration online system based

on the SensorML standard of version 1.0.1, and registers an in

situ sensor to Sensor Observation Service(SOS) successfully by

this system.

I. INTRODUCTION

With the development and popularization of Internet of

things (IOT), the sensors are increasingly integrated into our

daily life and work. It is estimated that by 2020, the amount

of Internet access sensors will reach 50 billion [1]. At

present, because of the differences in the hardware and

software, Sensor Networks composed of a plurality of

sensors in different fields still could not have a good

combination of data sharing, which creates the phenomenon

of "islands of information". In this era of big data, the

presence of "islands of information” is not conducive to

allocating sensor data efficiently and sharing data. To

eliminate the differences in the hardware and software of

Sensor Network, NASA proposed Sensor Web, the

combination of Sensor Network and the Internet platform,

built by the network technology, Service Oriented

Architecture (SOA) and Sensor Network. Users could have

the access to Sensor Network by utilizing standardized

protocols and packaged application interfaces through the

Internet. By this way, they could request services, subscribe

to news and receive notifications through multiple platform

services. To further normalize the discovery, access and use

sensor information through the Internet, build a

"plug-and-play" Web-based sensor network standard

platform, interoperate with multi-source heterogeneous

sensor and share data, Open Geospatial Consortium (OGC)

proposed the Sensor Web Enablement (SWE) framework in

2005, which has been widely recognized by the industry and

has became the de facto industry standard [2,4].In Sensor

Web, the basis of sharing sensor observation information is

the sensor modeling and sensor registration [7]. To make

this step forward, OGC proposed the Sensor Model

Language (SensorML) in SWE [8]. This is an information

standard for providing the related sensors information and

establishing the sensor information models. With this

standard all the physical platforms and logical algorithms of

the sensors would be expressed in the Process model or the

ProcessChain model [5]. The SensorML standard defines the

XML Scheme coding structure of the models. A sensor

model complied with SensorML standards is a document of

XML format that conforms to the Schema XML coding

structure. Sensor Web could register the sensors by

analyzing these documents. Although XML is plain-text

storage independent of the hardware and software which can

guarantee the data sharing and transmission between the

system and the software that is not compatible, it is not easy

for an ordinary user to build a SensorML document of XML

format and register the sensor to SOS use it. The scheme of

this paper is complied by SensorML coding standards, but

shielding the specific bottom implementation of sensor

model documentation. This scheme divides the sensor

modeling into several processes and constructs an online

user interface of fast sensor process for modeling and

registration, realizes a system of user-oriented fast sensor

process modeling and registration by forms.

II. CONCEPTUAL MODEL OF SENSOR DESCRIPTION IN

SENSORML

In order to manage centralized and use the multi-source

sensor observation information, OGC proposed the

SensorML standard. SensorML defines two types of data:

simple data and complex data, these two types of data can be

used to describe sensor related properties and sensor

interfaces. The related properties contain location, time, data

encoding, phenomenon, observation properties, input and

output, etc. It provides the information basis for describing

the sensor and processing the sensor data, which are

encapsulated in the Process and ProcessChain of the sensor

model as the basic information of sensor.

The Process and the ProcessChain are the core models of

SensorML. In SensorML, all of the components will be

modeled as Processes, in which the inputs, outputs, and
