The application fields of IoT mainly include logistics, průmyslová výroba, přeprava, zdravotní péče, personal and social fields, intelligent environment (home, office, factory), atd.

IoT architecture and implementation technologies at all levels

Architectures

IoT architectures are typically divided into three or four layers. The three-layer architecture consists of a network layer, aplikační vrstva, and sensor layer from bottom to top. The four layers of architecture from bottom to top are the platform tool layer, sensor layer, network connection layer, and application service layer. The difference between layer 3 and layer 4 architecture is that Layer 4 divides the “aplikační vrstva” of layer 3 into “platform tool layer” a “application service layer”, and makes a more detailed distinction between software applications.

The sensing layer

Addressing resources

The implementation of the Internet of Things requires that each object connected to the Internet of things be assigned a unique identity or address. After the IoT is connected to the Internet, it is estimated that a large number of IP addresses are needed. V současné době, the mainstream IPv4 address space is limited, so the objects in the Internet of Things tend to use the next-generation Internet Protocol (IPv6) to provide enough address space.

Network layer

There are a variety of networking technologies for the Internet of Things to choose from, which can be divided into short-range wireless, medium-range wireless, long-distance wireless, and wired technologies according to the effective transmission distance:

Short-range wireless communication

Bluetooth Mesh Networking – Standardizes mesh networking using Bluetooth technology, increasing the number of nodes and providing a standardized application layer.

Wi-Fi – Using visible light for increased bandwidth. is a wireless communication technology similar to the Wi-Fi standard.

NFC — A communication protocol that enables two electronic devices to communicate within 4 cm of each other.

RFID – Technology that uses electromagnetic fields to access data in Radio frequency identification (RFID) značky.

Wi-Fi – A wireless LAN technology based on the IEEE 802.11 Standard.

ZigBee – A personal network communication protocol based on IEEE 802.15.4 Standard, featuring low power consumption, low data rate, a nízkou cenou.

Z-wave – A wireless communication protocol primarily used in smart homes and security applications.

Mid-range wireless communication

5G – a new generation of mobile communications technology that provides reduced latency, high data rates, large-scale device connectivity, energy savings, and increased system capacity.

LONG-RANGE WIRELESS COMMUNICATION

LPWAN – Provides Low data rate and remote communication, reducing Power consumption and transmission cost. Available LPWAN technologies and protocols include NB-IoT using licensed bands, LoRa, Sigfox, Beztíže, Random Phase Multiple Access (RPMA), AND IEEE 802.11ah using unlicensed bands.

Very Small Aperture Terminal (VSAT) – communication technology transmitted through satellites using a Small dish antenna.

Wired

Ethernet – A technology based on the IEEE 802.11 standard that can be connected to a hub or network switch using twisted-pair cables and optical fibers.

PLC — Communication technology that transmits data and power by cable, with standards such as G.Hn and HomePlug.

Application layer

The application layer can be subdivided into “application service layer” a “platform tool layer” in the four-layer architecture of the IoT. The platform tool layer is the software platform of the bottom layer, which serves as the interface between the network layer and application service layer to support various software applications. The “platform-tools layer” includes big data, blockchain, software-defined networks, software-defined storage, software-defined data centers, secure communications, anti-virus software, artificial intelligence-related (např., zpracování přirozeného jazyka, hluboké učení, speech recognition, pattern recognition, computer vision…) And so on; The application service layer directly presents the original data for different application requirements, or through value-added processing, provides users with a human-machine interface, or the corresponding hardware/software target to get the desired information. Can be categorized as an “application services layer” including VR/AR, HCI, service-oriented architecture, sustainable development-related (life cycle assessment, úspora energie, carbon footprint…) And so on.

In the application layer, applications are usually written in multiple programming languages, using HTTPS and OAuth protocols. Use various forms of database systems on the back end of the platform, such as time-series data or back-end data storage systems (Cassandra, PostgreSQL, atd.).

Most IoT systems are built on cloud computing, kde jsou k dispozici systémy řazení událostí a zasílání zpráv, které zvládnou komunikaci na všech úrovních. Někteří odborníci klasifikují tyto tři vrstvy v průmyslovém internetu věcí (IIoT) jako okraj, plošina, a podnikání, které jsou propojeny přes sousední sítě, přístupové sítě, a servisní sítě, respektive.

3. Jaké jsou způsoby nasazení aplikací IoT

Nasazení IoT zahrnuje

1. Soukromý IoT, která poskytuje služby v rámci jedné organizace;

2. Internet veřejných věcí, Poskytování služeb veřejnosti nebo velkým skupinám uživatelů na internetu;

3. Komunitní internet věcí;

4. Mix networking.

Mezi režimy nasazení IoT patří:

Soukromý IoT

Služby poskytované v rámci jedné organizace může implementovat a udržovat organizace nebo třetí strana pověřená organizací. Řídicí inženýrská síť je chráněna autorským právem, mainly in the internal network of the organization, but also outside the organization.

Public IoT

Internet-based services to the public or large user groups are typically operated by an organization (nebo, to a lesser extent, a third party entrusted by it).

Community IoT

To provide services to a group of institutions (např., various commissions under a city government: transportation bureau, environmental protection bureau, public security Bureau, urban management Bureau, atd.) or an associated “společenství”. The operation and maintenance may be coordinated by two or more organizations, mainly on the Intranet and network.

Hybrid IoT

It is a combination of two or more of the above IoT, but with a unified operation entity behind it.

What technologies are being used for IoT deployment

When looking for the right solution, it is important to provide options because each use case has different connection requirements. Early adopters of the Internet of Things have used cellular, Bluetooth, and Wi-Fi connectivity, especially in use cases that require ultra-high reliability, extremely high availability, and low latency. Each solution will play a key role in determining the best deployment of iot networks.

5G

Zatímco 5G offers data rates, lower latency, higher capacity, and a core network of software designs, it also has a short-range across the mmWave spectrum, can be costly to deploy, and comes with a complex ecosystem.

Wi-Fi

The benefits of taking advantage of Wi-Fi include simplified cost-efficient deployment, can be seen as a strong alternative to 5G, and offers open roaming. nicméně, Wi-Fi offers limited coverage, limited security, and high energy consumption.

Bluetooth

The advantages of deploying Bluetooth include low cost, ease of deployment, and no hardware required to take advantage of the technology. nicméně, it has the characteristics of short-range, nízká šířka pásma, and short connection time.

LoRa

LoRa works well in use cases requiring low battery consumption and remote capabilities can be deployed in a cost-effective manner and provide an open business model for both public and private deployments. nicméně, this technique is not ideal when use cases require high data rates or applications that require low latency.

LPWAN is suitable for remote and low power consumption

For use cases that require remote and low-power connections, LPWAN is the best choice. The technology can be deployed at sea, in space, and on land, allowing sensors to transmit information wirelessly over a wide area without much effort. Internet of thing solutions with remote, low-power capabilities provide connectivity for traditional internet of things applications and incredible bandwidth for critical infrastructure across a variety of use cases worldwide

World’s top 10 Aplikace internetu věcí

The top 10 IoT applications are equipment monitoring, machine and infrastructure maintenance, logistics and tracking, container environment, machine management inventory, network data for marketing, identification of dangerous websites, driverless trucks, WAN monitoring, and GPS data aggregation.

Ten applications:

Equipment monitoring

Things like monitoring or adjusting a building’s thermostat can be done remotely, even to save energy and simplify maintenance procedures. The beauty of this IoT application is that it’s easy to implement, easy to tease out performance benchmarks, and get needed improvements.

Machinery and infrastructure maintenance

Sensors can be placed on infrastructure materials and equipment, such as railway tracks, to monitor the condition of these components and raise an alarm while something goes wrong with them. Some urban traffic authorities have already adopted this IoT technology to proactively maintain faults before they occur.

Logistics and tracking

The transportation industry now attaches sensors to moving trucks and individual parts that are being transported. The central system tracks these shipments from the start to the end. Doing so prevents theft in remote locations and keeps the corporate supply chain on track because management can clearly see where the vehicle is (and should be) at any point in time.

Container environment

Also in the logistics and transportation industry, kontejnery přepravující zboží podléhající rychlé zkáze jsou monitorovány z hlediska okolních podmínek, a senzory spustí alarm, pokud jsou mimo rozsah teploty nebo vlhkosti. navíc, senzor spustí alarm při porušení těsnění nebo narušení nádoby. Tyto informace jsou zasílány přímo těm, kdo rozhodují, prostřednictvím centrálního systému v reálném čase, aby bylo možné situaci napravit, i když je zboží v tranzitu po celém světě.

Inventář řízení strojů

Přenosné obchody a samoobslužné prodejní automaty, které nabízejí spotřebitelům různé položky, mohou nyní odesílat automatické upozornění na doplnění, když konkrétní položky poklesnou pod úroveň objednávek. To šetří peníze maloobchodníkům, protože potřebují, aby terénní pracovníci doplnili zásoby, když je to potřeba.

Webová data se používají pro marketing

Companies can choose to use their own analytics to track customer behavior online, or they can outsource the task to a marketing firm with a reputation in the field. In site navigation mode, visitors to and from your site, the types of devices they use, and other relevant data about visitors can be aggregated to get a fuller picture. The combination of transaction data and IoT data will enrich your marketing analytics and forecasts, which can be implemented quickly.

Identifying dangerous Websites

Security services offered by commercial companies allow network administrators to track Internet site visits, track machine-to-machine communications from corporate computers, and uncover IT addresses and “dangerous” websites regularly visited by corporate computers. Practice reduces the risk of malware and malware on your network.

Driverless truck

In remote areas with no road infrastructure and harsh weather conditions, companies in the gas and oil extraction industry are using driverless trucks that can be remotely communicated and controlled.

WAN monitoring

Businesses can well monitor and modify their network traffic, but when that traffic is routed through a wide area network or the Internet, it sometimes seems to be out of their control. Routers at the edges of offices in different locations around the world now show a significantly different quality of service, depending on whether the office is in Singapore or Rio de Janeiro.

GPS data aggregation

GPS data aggregation is one of the most popular data collection methods for the Internet of Things. Businesses like it because it lets them count weather data, graphical data, infrastructure data, demographic data, and any type of data that can be pinpointed to a specific geographic location.

5. Principles for IoT application developers

IoT projects should follow four important principles

Security is central to every solution, and the Internet of Things is no exception. Here are four guidelines integrators should follow to ensure IoT projekty are as secure as possible.

Equipment safety is of paramount importance

IoT devices are the most vulnerable part of IoT networks because they typically use simple processors and operating systems that may not support advanced security features. They are also the largest in terms of the number of units and the diversity of products and manufacturers. That makes IoT řešení that protect billions of devices potentially complicated.

To make matters worse, IoT devices lie outside the boundaries of traditional networks and are often installed and managed by non-IT organizations in open and unprotected places such as farmland, parkovací místa, and factory floors.

“One particular IoT device may be secure, but another may be vulnerable,” explains Benson Chan, senior partner at Strategy of Things. With billions of IoT devices expected to be deployed in the coming years, hackers are increasingly focusing on this area.”

Protect network Security

The one thing all IoT devices have in common is an Internet connection, without which they’re really just “things.” Proto, networks connecting IoT devices must be protected by traditional end-security tools such as antivirus and anti-malware, firewalls, and intrusion prevention and detection systems.

Know your device

Device authentication is critical to network protection. If an unauthorized device is detected, the operation must be automatically started. “This operation may include disconnecting devices, blocking traffic and notifying administrators,” Benson Chan noted. The first step in securing an enterprise network should be to isolate it from the Internet of Things network so that internet-related vulnerabilities have no chance of infecting other systems.

Automated IoT device management

Managing IoT zařízení is complicated by the sheer number of devices to focus on. But continuous management is necessary because each device has its own weaknesses. “To use IoT device management and automation tools, the more IoT devices in the network, the more difficult it is to manage,” Advises Benson Chan. The use of automated tools simplifies the administration process, reduces errors and missing devices, and ensures that all operations are applied consistently across all devices.

At a minimum, management means setting appropriately strict security levels prior to deployment, regularly checking and updating firmware, and working hard to apply security patches.

Iot security practices and tools are evolving, and checking systems regularly is the only way to keep devices on a distributed network secure.

6. Frequently asked questions about the Internet of Things applications

Intellectual Property

In the process of productization of Technologie internetu věcí, China has been lacking in the mastery of some key technologies, so the product level cannot be improved and the price cannot be lowered. Nedostatek nezávislých vlastnických práv pro klíčové technologie, jako je RFID, je jedním z klíčových faktorů omezujících rozvoj internetu věcí v Číně..

Technická norma

V současnosti, průmyslová technologie postrádá především následující dva aspekty standardů: standardizace rozhraní; Standardizace datového modelu Čína sice založila RFID průmyslovou alianci již v listopadu 2005, ve stejnou dobu, Čínská radiofrekvenční identifikace (RFID) V následujícím roce byla vydána bílá kniha o technologické politice, poukazuje na to, že bychom se měli zaměřit na výzkum a vývoj základní technologie RFID, vyvinout technické normy v souladu s čínskými národními podmínkami Ale teď, můžeme zjistit, že RFID průmysl v Číně je stále nepořádek technologie síla se zvyšuje, ale technický standard, ale také jako zrcadlo měsíce Je jako Čína 3 g standardní, pro zájmy všech aspektů, Konečně, čínské 3 g se třemi různými standardy internetu věcí konečně jak, můžeme jen čekat na čas, aby nám řekl odpověď.

Průmyslový řetězec

Ve srovnání s americkým domácím dokonalým stupněm průmyslového řetězce internetu věcí, jsou velké mezery I když současní domácí tři velcí operátoři a ZTE, Výrobci tohoto druhu systémového vybavení společnosti Huawei jsou na světové úrovni, ale v jiných částech relativně chybí průmysl internetu věcí nezbytně potřebují dodavatelé čipů řešení systému snímání zařízení pro výrobce navazujících a navazujících výrobců, jako jsou mobilní operátoři, aby spolupracovali, Proto, za účelem rozvoje internetu věcí v Číně, there is still a lot of work to be done in terms of the system, such as strengthening the cooperation between competent departments of radio, television, telecommunications and transportation industries, jointly promoting the establishment of information and inteligentní dopravní systém and speeding up the integration process of telecommunications network, broadcasting power grid and Internet The cooperation of the industrial chain needs to take into account the interests of all parties, and the popularization of the Internet of Things is still quite long under the background of the interest mechanism and business model of all parties not yet formed.

Industry collaboration

IoT application field is very wide, with many great and cross-industry applications, but these industries points belong to different government functional departments, to develop the Internet of things the sensing technology-based information application, in the process of industrialization, must strengthen the industry department in charge of coordination and interaction with an open mind on work together to break the department of industry areas Only by promoting resource sharing and strengthening institutional optimization and reform, can the smooth development of the Internet of Things industry be effectively guaranteed.

Profit model

Iot into perception, sítí, and application of three levels, on every level, there are so many choices that will go to exploit market, so in the process of the construction of ecological environment in the future, the business model is the key For any of the information industry revolution, the emergence of a new type and the business profit model is the inevitable result of the development of mature, but it is so far It is not reflected in the development of the Internet of Things, and no industry can uniformly lead the development of the IoT. V současnosti, some economic benefits directly brought by the development of the Internet of Things are mainly concentrated in the electronic components related to the Internet of Things. It will take a long time to see the opportunities that huge data flows will bring to network operators and the impact they will have on downstream industries such as logistics and retail.

Use Cost

IoT industry is the need to connect objects and things to better control and manage This characteristic determines its hair Exhibition will bring along with the economic development and social needs and create more applications So, in the Internet of things sensing technology promotion at the beginning of the period, single function, the problems of high price is hard to avoid Because, electronic tags, reading and writing equipment is expensive, so it is difficult to form Into a large-scale application.

And because there is no large-scale applications, electronic tag and the cost of the read/write device will remain not reached the expected cost is high, there are no large-scale applications, and no large-scale applications, the problem of the high cost of more difficulty solving how to process the user in terms of cost of early barriers became the primary problem of open this a slice of the market So the cost has not been down to you can And the development of the Internet of Things will be limited.

Safety problem

In the Internet of things, the construction of the sensor network for RFID tags embedded in advance any items which are closely linked with the people can see people on the concept of life all around him, it seems, are still not very can accept items including yourself all the time is in a state of being monitored, this led directly to the embedded tags are bound to make personal privacy issues are violated. Proto, the privacy of the owner of the signature is a key issue for the promotion of Technologie RFID and the Internet of Things. And if the government cooperates with large foreign enterprises in this respect, how to ensure that business information and state secrets will not be leaked is also crucial So, at this point, the development of the Internet of Things is not just a technical issue, but more likely involves political, legal and national security issues.
