1. What is the Internet of Things?
The Internet of Things is not only the interconnection of networks and objects, enterprises, people and everything, but also the business and application of information technology. It is the use of communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people and things together in a new way, forming a connection between people and things, things and things, and realizing informatization, remote management control and intelligence network of.
Second, what is the use of the Internet of Things?
The Internet of Things is everywhere and at all times, bringing perfect convenience to human beings. An internationally unified Internet of Things standard will promote the explosive growth of the Internet of Things. When tens of billions of items are connected into a network, the resulting IoT Networked big data applications will be unimaginable.
1. In public places, countless "things" are exchanging data and constantly "reminding" and recording.
2. At home, all kinds of electrical appliances, ranging from switches and plugs to TVs and washing machines, will communicate with each other and automatically prepare the daily needs of you and your family.
3. On the road, unmanned driving will become the norm. You can free up your hands to send and receive emails and make phone calls, and the car will take you to your destination by itself.
4. In the office, conference calls are outdated, and the mobile phone will automatically display the holographic image of the person you need to contact; the coffee machine will remind you that the coffee beans are about to run out; the refrigerator will tell you that the milk and yogurt are about to expire.
5. In the warehouse, the goods in and out of the warehouse are automatically recorded, and the inventory count is completed with one click.
6. On the way home, the vacated kitchen refrigerator will automatically order the required meat, eggs, vegetables and fruits, and notify you to go directly to the supermarket to pay and pick up the goods.
3. The Internet of Things is the Internet of Everything
In this huge network, if an item does not have an identification code that conforms to the rules, it cannot interact with other items. OID is the Internet of Things meta-identification determined by the three major international organizations. After an item is assigned an OID, it is equivalent to receiving it in A passport to the world of the Internet of Things has the right and convenience to interact with other items marked with OID.
4. What does the Internet of Things rely on to achieve interconnection?
In order to enable the interconnection of various "local Internet of Things" and even individual items, a super protocol that is compatible with various coding and standard protocols and can be seamlessly integrated with the Internet is needed to unify the network. Scientists have developed A kind of identification called Open Object Identifier or OID. This is a protocol standard rule and coding method for global compliance. It is jointly promulgated and implemented by ISO (International Standards Organization), ITU (International Telecommunication Union) and IEC (National Electrotechnical Organization). It is currently used by 208 countries and regions around the world. adopted by the region.
5. What is the difference between IoT OID and Internet domain name?
1. The leading organization is different, and the OID of the Internet of Things is uniformly assigned by the international standard organization that participates in the world. Each country manages its own territory, and they can communicate with each other. The security mechanism is higher than the Internet domain name, with both a high degree of autonomy and global interoperability. China is the biggest supporter and user of the whole system.
2. The form of expression is different. The OID node and length of the Internet of Things are not limited. Theoretically speaking, it can be defined to every grain of sand in the sea.
3. Terminals are different. IoT OID defines item terminals (whether physical or virtual), while Internet domain names define computer terminals.
6. What is the relationship between OID and the Internet of Things, blockchain, and big data?
The Internet of Things is a big concept. OID, blockchain, and big data are all small concepts. OID, blockchain, big data, and the Internet of Things all have a great relationship. OID is an item identification, and it is a dependent relationship with the Internet of Things. , With the Internet of Things, it is necessary for OID to exist. As mentioned above, the OID is the identity of the item. If the company that manufactures the item wants to have the item with an ID, first of all, the company itself must first obtain the ID of the Internet of Things, that is, the OID. In terms of specific operations, it is called registering the OID. Since the OID is registered , you need a system and method to resolve OID. This is the relationship between the so-called OID technology and the Internet of Things. OID uses IoT technology to connect all aspects of the domain.
7. How to identify OID, trace the source, and prevent counterfeiting?
The reshaping of the industrial chain structure by the OID system is very obvious, changing the long linear value chain of "upstream-midstream-downstream" in most traditional industries; with the development of the information industry, big data can truly monitor user behavior Analysis, so as to feed back to the upstream, is conducive to the adjustment of industrial structure and the digital transformation of the real industry. Divided into four levels in technology application
(1) Perception layer: data collection (generate management data, production data, inflow and outflow data, etc.);
(2) Communication layer: data upload (real-time recording);
(3) Storage layer: data cloud storage;
(4) Application layer: various applications (sales data, market preference data, consumer behavior data, etc.).
It can be seen from this that as long as OID has applications, it will inevitably form big data, from item production data, circulation data, sales data, consumption behavior, preference data, all will enter the storage layer (public cloud, private cloud and other clouds) , forming massive data, so various big data will be generated through OID applications. Without OID applications, there will be no accurate big data in the Internet of Things society. Of course, big data is also inseparable from the popularization of various business forms of the Internet of Things. OID makes it impossible to tamper with any original record data, which is advantageous for anti-counterfeiting and traceability of products. At the same time, the data gathered by OID is not only undisclosed, but also highly confidential. This is obviously different from the blockchain. OID focuses more on the overall regulatory needs.
