Be alert to the island effect not to let the Internet of Things evolve into a "thing show" The Internet of Things is like a galloping train. Since the loud whistle in 2009, local governments, scientific research institutes, enterprises, and industry users have scrambled to board this train. The development of the Internet of Things has a very important role and significance for China's role and strength in the future world economy. Planning, standards, and supportive policies are coming in one after another. Where will this train of things go? The development speed of the Internet of Things is unexpected. All links in the industry chain are running and equipped, fearing backwardness, and always looking around in the process of rushing forward, trying to find a clearer direction for the Internet of Things. Queries followed: Is the Internet of Things a show? The Internet of Things is not a "thing show" The boss of a supermarket in a county tried to meet a VC, claiming that his supermarket is the Internet of Things, hoping to get investment and promote his "supermarket + software" model. His argument is that all the goods can be scanned, and the information can be entered into a small management program he bought at any time, and passed to the county information service station, even the villagers can always know the stock situation, so he is very confident that he already has " The hype concept of "Internet of Things". This is just a joke, but it is enough to prove that the concept of the Internet of Things is like a big sucker, and it is attracting the real and fake Internet of Things projects. No wonder some people question whether the Internet of Things is a show? The Internet of Things has a very wide scope and involves all aspects. But so far, there is not a very accurate concept and definition. Different people interpret the Internet of Things from different perspectives from different starting points. To this end, on January 15th, the "Computer World" newspaper invited government, enterprises, industry users, and scientific research institutes representatives to gather together to discuss the Internet of Things, and strive to use different perspectives to analyze the Internet of Things. Internet of Things "Local Area" Network "The Internet of Things is not a show, but an inevitable result of the development of information technology to a certain stage. In the end, what the Internet of Things is, the relevant departments will give a relatively objective definition in the near future." Zhao Zhuang, the deputy director of the research center, believes that "the definition should be narrowly defined, otherwise the Internet of Things will cover too much." The Internet of Things cannot be defined "blindly like the elephant" and described from a certain angle or an application. None of the Internet of Things is comprehensive and accurate. Many cities across the country are already demonstrating or constructing IoT projects. However, the IoT is not just as simple as adding a “perception†or “Internet of Things†in front of the city name. Each region has different characteristics and should have its own personality. The development of the Internet of Things, and planning should focus on the long-term, it should not be anxious. And no matter what the final definition of the Internet of Things will be, broad or narrow, or just like the beginning of the development of the Internet, it will not pursue a strict definition at all. From the scope of application alone, in fact, the current Internet of Things applications have been scattered In various fields, these applications are only closed-loop applications, which can only be regarded as a node of the Internet of Things, but it does not mean that the Internet of Things is all. The railway RFID oligarch Yuan Wanggu has already made its mark in the tide of the Internet of Things, and it can also be seen that the railway transportation industry is the first wave of applications for the Internet of Things. Railway number identification is the largest application market of UHF RFID technology in China. The Ministry of Railways has invested a total of nearly 1 billion yuan. At present, the company has installed electronic tags on 400,000 railway trucks nationwide, and installed more than 3,000 RFID reader systems on 80,000 kilometers of railway lines. In 2010, large-scale railway construction will continue, and a large number of high-speed railways, passenger dedicated lines, and freight passages will be built. "The railway system has long been using RFID technology, and the unique characteristics of commodities can be identified through RFID tags, so that the goods can be tracked in all links of transportation, so that the cargo owner can grasp in real time which links of commodities are in transportation." Ministry of Railways Information Center Zhu Guang Guang said, "RFID technology is an application of the Internet of Things, which has played a very important role in increasing the throughput of distribution centers, shortening the operation process, and reducing operating costs." In industries closely related to the Internet of Things, first, there is an urgent need, and second, there must be strong capital. Sensors have a long history of application in the power industry, and the scope of application is also relatively wide. Commonly used are Street Lamp wireless control, remote meter reading, etc. From the current perspective, they can all be regarded as an application form of the Internet of Things. Grid companies use sensor networks, Internet of Things and other technologies to timely obtain power system operation information from various aspects such as power load, strengthen power load forecasting, improve power grid operating efficiency, and achieve reliable power supply. In addition to electricity and railways, the "awareness" of the agricultural field has long existed. Wu Huarui, director of the Software Engineering Department of the Beijing Agricultural Information Technology Research Center, said: "The Internet of Things has great application prospects in the agricultural field. For example, in large-scale farmland, orchards, etc. In terms of production, it is necessary to collect the temperature, humidity, light, rainfall, and organic matter content, temperature and humidity, heavy metal content, and PH value of the agricultural small environment for real-time transmission and use. For scientific fertilization and irrigation operations, It is a very important and meaningful subject. In the circulation of fresh agricultural products, the temperature of the storage and transportation environment and the moisture of the agricultural products need to be controlled. Excessive environmental temperature may cause the rot of a large number of agricultural products, and insufficient moisture will affect the quality. Another type of application with typical significance is factory-based healthy breeding operations, which require dynamic monitoring and control of livestock and poultry and aquaculture environments through the Internet of Things technology. " From this point of view, the Internet of Things is not "empty", and some industries with more in-depth information applications have already adopted the Internet of Things technology. Prevent new islands of IoT The application of the Internet of Things is scattered in various industries. From August last year to now, all regions are also vigorously planning the layout of the Internet of Things project, but this will inevitably bring another hidden danger, that is: in standards, technology, policies, etc. In a very clear situation, the rapid construction of the Internet of Things may cause new information islands. On the other hand, existing information technology platforms can support IoT single-point or closed-loop applications, but if there are 10 trillion or more terminal services entering this network in the future, the existing platforms may no longer be sufficient to support this scale Application, you need to make adjustments from the entire technical framework. Beijing will promote the “Perceived Beijing†demonstration project this year, using the Internet of Things technology to carry out application demonstrations in the three major areas of society, enterprises and government. For example, in terms of railway freight logistics, there is such a problem. Because the details of the regulations are not uniform, the containers on the railway may not be able to read the information when they arrive at the port, and the containers on the railway may not be able to exchange information because of the inconsistency of the label specifications. . "Although the type and size of the container itself have international standards, but to meet the information exchange system of the Internet of Things, all interfaces and communication protocols need to have national standards and need to be refined." Zhu Guang said. From closed loop to open loop, from a single node to a platform, it also needs the support and encouragement of the government. The Beijing Municipal Commission of Economy and Information Technology will promote the "Information Benefits to People" and other action plans this year, using the Internet of Things technology for pilot applications in the fields of health care, environmental meteorological monitoring, and agricultural monitoring. Gao Shunwei, Director of the Planning Department of the Information Resource Management Center of the Beijing Municipal Commission of Economy and Information Technology, said: "Government applications are also a relatively important direction in the application of the Internet of Things. The platform and other foundations, together with other shared support functions for IoT applications, should be able to be competent for the basic platform facilities of IoT applications in the government area. " Security cannot be ignored The extension of the Internet of Things from the information world to the physical world may bring a series of security issues. It uses radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners, and other information sensing equipment to connect any item to the network according to the agreed protocol, and exchanges and communicates information to achieve intelligent identification, Positioning, tracking, monitoring and management. From this analysis, there are many nodes vulnerable to security attacks in the entire link of the Internet of Things. Taking the power industry as an example, although wireless sensor technology has been widely used, it is still just a start. Some experts believe that: "Because power is a basic industry related to international livelihood, it is the foundation of the national economic foundation. Electricity security is a fundamental premise. Any application of technology must be guaranteed by security. Security problems cannot be solved, and no one dares to use them or use them. "To some extent, the Internet of Things has developed the largest The obstacle may still be the security of the Internet of Things. Strengthening the research on the Internet of Things security and exploring the establishment of a demonstration of the Internet of Things security application is an urgent matter that is related to the success or failure of the Internet of Things application. Li Ziqing, director of the Research Center for Biometrics and Security Technology, Institute of Automation, Chinese Academy of Sciences, said: "When it comes to security issues, there is also privacy security, because the Internet of Things will deal with people in addition to connecting objects, such as health sensors and video surveillance. The device will more or less involve people ’s privacy, but regarding privacy protection, China has no corresponding standard policy. " At the sensor layer, network layer and application layer of the Internet of Things, the security threats faced will only be more, not less than those in the Internet. However, it is not possible to choke on food because of safety, and an active protection strategy should be adopted as soon as possible.
