Recently platform for how to build things, we had targeted discussions and exchanges, essentially unity of thinking, reached the following understanding.
First, the construction of Things platform is currently a major opportunity! Second spring lies not only in things their own development, more importantly, is a national strategic decision, a major task of things as a new infrastructure, its follow-up to the national economy has a significant spillover effect.
Second, the Internet of Things platform is the key to the current wisdom of urban construction, is the top priority. After exploring smart city after another to always have to act as a vanguard in the new urbanization process, especially in the important task of information technology. And no systematic start from the city full sensory hard to build a high level of urban management and support system. We also called the city lifeline system, like human limbs and facial features, to fully coordinate the development.
Third, networking platform and big data platform indivisible, will form a unified whole. Past experience, big data platform for building more prominent building data processing and data centers. The Internet of Things platform level as the latest new four-tier structure of things, becoming intermediate links, connecting link. In many cases, the Internet of Things platform by people simply interpreted as data acquisition, so that only see the surface, no in-depth understanding of what things?
Fourth, the establishment of a large city than just data office for operation and management of big data, more importantly, the city's comprehensive system for the full range of operations and services. This requires from the most basic sense, wear, office, with different security, clothes and other six dimensions to rethink the wisdom of urban design and development and the future, particularly all-round integration of urban and urban lifeline systems of the brain.
Fifth, the data come from the big things? What is the nature and characteristics? Existing large data from more people-oriented phase of the Internet, and things of big data will be explosive growth hundred thousand times, which for the human experience, it will be a new experience!
We have to think of things big data!
1. polymorphism and heterogeneous data
Collecting data in a variety of sensors, and each type of sensor use in different applications there are different systems. Clearly, these various sensor structures, different performance, which acquires the data structures vary. In RFID systems, there are a plurality of RFID tags, various reader; the M2M system microcomputer computing device is shaped shape ×××. Their data structure can not follow a uniform pattern.
物联网中的数据有文本数据，也有图像、音频、视频等多媒体数据。有静态数据，也有动态数据（如波形）。数据的多态性、感知模型的异构性导致了数据的异构性。物联网的应用模式和架构互不相同，缺乏可批量应用的系统方法，这是数据多态性和异构性的根本原因。显然，系统的功能越复杂，传感器节点、RFID标签种类越多，其异构性问题也将越突出。这种异构性加剧了数据处理和软件开发的难度。
2. 数据的海量性
物联网往往是由若干个无线识别的物体彼此连接和结合形成的动态网络。一个中型超市的商品数量动辄数百万乃至数千万件。在一个超市RFID系统中，假定有1000万件商品都需要跟踪，每天读取10次，每次100个字节，每天的数据量就达10GB，每年将达3650GB。在生态监测等实时监控领域，无线传感网需记录多个节点的多媒体信息，数据量更大的惊人，每天可达1TB以上。
此外，在一些应急处理的实施监控系统系统中，数据是以流（stream）的形式实时、高速、源源不断地产生的，这愈发加剧了数据的海量性。
3. 数据的时效性
被感知的事物的状态可能是瞬息万变的。因此不管WSN还是RFID系统，物联网的数据采集工作是随时进行的，每隔一定周期向服务器发送一次数据，数据更新很快，历史数据只用于记录事务的发展进程虽可以备份，但因其海量性不可能长期保存。只有新数据才能反映系统所感知的“物”的现有状态，所以系统的反应速度或者响应时间是系统可靠性和实用性的关键。
这要求物联网的软件数据处理系统必须具有足够的运行速度，否则可能得出错误的结论甚至造成巨大损失。
4. 数据传输的难题
对于WSN而言，国内物联网应用研究表明文本型数据易传难感，多媒体数据易感难传；在出现数据传输故障时，很难判定是网络中断还是软件故障；理想化的系统模型假设因其忽略了WSN运行过程中伴随的各种不确定的、动态的环境因素往往难以实地应用！
面对以上现实中的问题和困难，如何有效解决物联网平台建设，特别是物联网大数据的海量处理问题将是下一阶段的重点和难点！
Of course, more solutions than problems! Through in-depth research, we will summarize past experience and relevant cases at home and abroad to inspect. Since things as the goal of the new infrastructure is established, then the next project believe that the second half will be a big wave of Things platform waiting for your participation!
Things will be the future of the world, let's meet 19-21 November 2019, similar to 2019 (Third) Global Assembly of things - looking thinker!
