IoT Applications

Category : 其他, 技术相关

According to Gartner, Inc. (a technology research and advisory corporation), there will be nearly 20.8 billion devices on the Internet of things by 2020. ABI Research estimates that more than 30 billion devices will be wirelessly connected to the Internet of things by 2020. As per a 2014 survey and study done by Pew Research Internet Project, a large majority of the technology experts and engaged Internet users who responded—83 percent—agreed with the notion that the Internet/Cloud of Things, embedded and wearable computing (and the corresponding dynamic systems) will have widespread and beneficial effects by 2025. As such, it is clear that the IoT will consist of a very large number of devices being connected to the Internet. In an active move to accommodate new and emerging technological innovation, the UK Government, in their 2015 budget, allocated £40,000,000 towards research into the Internet of things. The former British Chancellor of the Exchequer George Osborne, posited that the Internet of things is the next stage of the information revolution and referenced the inter-connectivity of everything from urban transport to medical devices to household appliances.

Integration with the Internet implies that devices will use an IP address as a unique identifier. However, due to thelimited address space of IPv4 (which allows for 4.3 billion unique addresses), objects in the IoT will have to use IPv6to accommodate the extremely large address space required. Objects in the IoT will not only be devices with sensory capabilities, but also provide actuation capabilities (e.g., bulbs or locks controlled over the Internet). To a large extent, the future of the Internet of things will not be possible without the support of IPv6; and consequently the global adoption of IPv6 in the coming years will be critical for the successful development of the IoT in the future.

The ability to network embedded devices with limited CPU, memory and power resources means that IoT finds applications in nearly every field. Such systems could be in charge of collecting information in settings ranging from natural ecosystems to buildings and factories, thereby finding applications in fields of environmental sensing and urban planning.

On the other hand, IoT systems could also be responsible for performing actions, not just sensing things. Intelligent shopping systems, for example, could monitor specific users’ purchasing habits in a store by tracking their specific mobile phones. These users could then be provided with special offers on their favorite products, or even location of items that they need, which their fridge has automatically conveyed to the phone. Additional examples of sensing and actuating are reflected in applications that deal with heat, electricity and energy management, as well as cruise-assisting transportation systems. Other applications that the Internet of things can provide is enabling extended home security features and home automation. The concept of an “Internet of living things” has been proposed to describe networks of biological sensorsthat could use cloud-based analyses to allow users to study DNA or other molecules.

However, the application of the IoT is not only restricted to these areas. Other specialized use cases of the IoT may also exist. An overview of some of the most prominent application areas is provided here. Based on the application domain, IoT products can be classified broadly into five different categories: smart wearable, smart home, smart city, smart environment, and smart enterprise. The IoT products and solutions in each of these markets have different characteristics.

 

Differences between industrial class and SOHO class for Router / Modem

Category : 其他, 技术相关

As we know, the devices mainly cover three classes, that is SOHO class, Industrial class and Military class.  Each class has its own application requirement. The SOHO class modem and router don’t meet the requirements of the industrial environment and standard entirely because of it is designed for office automation. Mainly differences are the below,

1. Control
The SOHO class is simple design for internet use. People no need control it very often.
The industrial class is designed mainly for industry applications. People need control it quite often, even 7*24 hours.

2. Stable, reliable and robust
SOHO class features are simply. It is mainly used for internet surfing, which is installed in house. People can check and assist it in time. With cost requirement, SOHO class design and development will not care too much for the stability and reliability. The industrial class cares the stability and reliability very much because it’s mainly installed under people’ touch. In another world, it should be working for 7*24 hours without people assist. So the industrial class must have good reliability, recoverability, and maintainability in the production environment at the same time. It is a guarantee that it will not lead the collapse of applications, operating system even the network when any component failure occurs in a network system.

3. The security issues
Lots of fields exist inflammable, explosive or toxic gases inevitably in the process of industrial production, and there must have some certain explosion-proof technology for the intelligent devices and communication equipment which can ensure the safety of industrial field. It is much more practical to add explosion-proof and explosion-proof measures in the Ethernet system under the condition of current technology, namely the ignition energy which caused by the devices problem will not leak through increasing explosion-proof measures to the Ethernet field devices, which can ensure the safety of running system. For those dangerous situation where is no strict safety requirements, you can not consider complex explosion-proof measures.

The network safety of industrial system is another security issue must be considered at the industrial Ethernet applications. Industrial Ethernet can make the traditional three layers of the network system, namely, information management layer, process monitoring layer and field equipment layer, an organic whole, which make the faster data transfer, higher real-time and it can integrate with the Internet seamlessly, it realizes data sharing and improves the operational efficiency of the factory. But there is a series of network security problems at the same time, industrial network may under the threat of virus infection, hackers and illegal operation.

4. The vehicle power supply issues
The vehicle power supply refers to the cable connected to the field devices not only to transmit data signals, but also provide equipment working power supply on-site. The Ethernet hasn’t considered this issue from the design at the beginning, while there are a lot of bus power supply requirements on the industrial site. Because of the above problems, the ordinary commercial Ethernet cannot be applied to the control of industrial field directly. And the industrial Ethernet is produced to solve these problems.

 

5. Features and performance
The industrial class owns much more features and SOHO class, such as connection alive monitor and keeping, Dual Sim connection, multi-line redundancy, GPS, Serial ports, VPN networks, high gain and special antenna replacement, etc.

Traffic Data Acquisition Application
Traffic Data Acquisition is among one important tasks in ITS. All the on-line or historical data are vital for the design and planning for the traffic management strategy. The traffic data acquisition device normal consists of two parts: the sensor and the controller. The controller links with the central through wire-line connection and send back the data collected from the sensor. However, installation of the wire-line relates to huge engineering efforts and the maintenance of fixed lines has always been difficult. There will be more problems to get wire-line connection in remote areas. When

the communication line goes down, data is lost unless a data Logger is further installed.

In this application, wireless module links with the Traffic Data Acquisition device using RS485 interface. The raw data from the detector is further analyzed by the data protocol analysis mechanism provided by the wireless module and sorted data is transmitted to the central Traffic Control Centre through GPRS network and Internet in TCP/IP packet. Data can be temporarily stored in the memory buffer when GPRS is disconnected. From the system integrator”s point of view, all the integration on the terminal wireless

connection is achieved by the plug & play of wireless module and no change is necessary on the original detecting device. And only simple application is required at the central to access the terminal data. The total system implementation is accomplished within 3 weeks.

A Quick Understanding of FTP/SFTP/FTPS/TFTP

Category : 伊林思产品FAQ, 其他, 技术相关

File Transfer Protocol (FTP)

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files from a server to a client using the Client–server model on a computer network.

FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server. FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS). SSH File Transfer Protocol (SFTP) is sometimes also used instead; it is technologically different.

 

SSH File Transfer Protocol(SFTP)

The SSH file transfer protocol (chronologically the second of the two protocols abbreviated SFTP) transfers files and has a similar command set for users, but uses the Secure Shell protocol (SSH) to transfer files. Unlike FTP, it encrypts both commands and data, preventing passwords and sensitive information from being transmitted openly over the network. It cannot interoperate with FTP software.

In computing, the SSH File Transfer Protocol (also Secure File Transfer Protocol, or SFTP) is a network protocol that provides file access, file transfer, and file management over any reliable data stream. It was designed by the Internet Engineering Task Force (IETF) as an extension of the Secure Shell protocol (SSH) version 2.0 to provide secure file transfer capabilities. The IETF Internet Draft states that, even though this protocol is described in the context of the SSH-2 protocol, it could be used in a number of different applications, such as secure file transfer over Transport Layer Security (TLS) and transfer of management information in VPN applications.

This protocol assumes that it is run over a secure channel, such as SSH, that the server has already authenticated the client, and that the identity of the client user is available to the protocol.

Simple File Transfer Protocol

Simple File Transfer Protocol (the first protocol abbreviated SFTP), as defined by RFC 913, was proposed as an (unsecured) file transfer protocol with a level of complexity intermediate between TFTP and FTP. It was never widely accepted on the Internet, and is now assigned Historic status by the IETF. It runs through port 115, and often receives the initialism of SFTP. It has a command set of 11 commands and support three types of data transmission: ASCII, binary and continuous. For systems with a word size that is a multiple of 8 bits, the implementation of binary and continuous is the same. The protocol also supports login with user ID and password, hierarchical folders and file management (including rename, delete, upload, download, download with overwrite, and download with append).

FTPS

Explicit FTPS is an extension to the FTP standard that allows clients to request FTP sessions to be encrypted. This is done by sending the “AUTH TLS” command. The server has the option of allowing or denying connections that do not request TLS. This protocol extension is defined in RFC 4217. Implicit FTPS is an outdated standard for FTP that required the use of a SSL or TLS connection. It was specified to use different ports than plain FTP.

Trivial File Transfer Protocol(TFTP)

Trivial File Transfer Protocol (TFTP) is a simple, lock-step FTP that allows a client to get a file from or put a file onto a remote host. One of its primary uses is in the early stages of booting from a local area network, because TFTP is very simple to implement. TFTP lacks security and most of the advanced features offered by more robust file transfer protocols such as File Transfer Protocol. TFTP was first standardized in 1981 and the current specification for the protocol can be found in RFC 1350.

Orange Business Services has won a three-year contract with Sensile Technologies for M2M connectivity, including 25,000 SIM cards, to support its two remote monitoring products worldwide: NETRIS®2 and GASLink®

Headquartered in Morges, Switzerland, Sensile Technologies is a pioneer in the internet of things (IoT) market. Specifically, it is a leading provider of solutions for the remote monitoring of tanks and meters in the oil and gas industry. Sensile Technologies monitors more than 60,000 tanks in industrial and business facilities across 60 countries, via a global network of highly-qualified technicians and local partners.

Up to now, Sensile Technologies used 2G compatible devices to power its telemetry solutions. The contract with Orange Business Services extends this to cover 3G/4G devices, which future-proofs the solutions against 2G network shutdown and ensures seamless global coverage.

Sensile Technologies’ telemetry solutions, GASLink® and NETRIS®2, play a key role in the monitoring process. They are installed directly in the oil or propane tank and regularly send tank level measurements via the GSM network to the cloud, where the data is automatically processed.

The up-to-date tank level data allows oil and propane merchants – and their haulers – to arrange deliveries automatically via planning tools. They get data directly in their enterprise resource planning (ERP) system from Sensile Technologies’ Oil Link cloud solution to trigger deliveries automatically. In addition, their customers can get access on smartphones to monitor consumption.

Thanks to the optimization of deliveries based on live data, merchants and haulers can lower their logistics costs by at least 25 percent, without the risk of customers running dry. In addition to mitigating the risk of running out of fuel, customers are also able to access a detailed visualization and analysis of their logistics, enabling them to adapt their processes to reduce their costs further.

“Leading oil and propane companies rely on our autonomous, robust, and easy to install systems. We have more than 60,000 in place on tanks in over 60 countries. Orange Business Services has proven itself as a reliable partner with the global footprint we need for our business. Their competitive flat-fee pricing was convincing as well,” said Jean-Marc Uehlinger, Operational Director, Sensile Technologies.

“With its telemetry solutions Sensile Technologies is helping drive the latest revolution in industry. In Industry 4.0 every part of the enterprise and each phase of the manufacturing cycle will be connected. The internet of things (IoT) and M2M play a key part in this revolution, and we manage 10 million connected objects for our customers worldwide, including over 7 million active SIM cards,” Anne-Sophie Lotgering, senior vice president Europe, Russia & CIS, Orange Business Services.

GASLink® and NETRIS®2 are the result of 15 years’ experience from Sensile Technologies in the development and production of autonomous telemetry equipment. In addition to using the 2G (SMS) network to transmit data, NETRIS®2 can also use 3G or 4G, as well as create a short-distance radio frequency connection, which functions in every location.

PPPoE–Point-to-point protocol over Ethernet

Category : 其他, 技术相关

The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating PPP frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packet sover the DSL connection to the ISP’s IP network, and from there to the rest of the Internet. A 2005 networking book noted that “Most DSL providers use PPPoE, which provides authentication, encryption, and compression.” Typical use of PPPoE involves leveraging the PPP facilities for authenticating the user with a username and password, predominately via the PAP protocol and less often via CHAP.

On the customer-premises equipment, PPPoE may be implemented either in a unified residential gateway device that handles both DSL modem and IP routing functions or in the case of a simple DSL modem (without routing support), PPPoE may be handled behind it on a separate Ethernet-only router or even directly on a user’s computer. (Support for PPPoE is present in most operating systems, ranging from Windows XP, Linux to Mac OS X.) More recently, some GPON-based (instead of DSL-based) residential gateways also use PPPoE, although the status of PPPoE in the GPON standards is marginal.

PPPoE was developed by UUNET, Redback Networks (now Ericsson) and RouterWare (now Wind River Systems) and is available as an informational RFC 2516.

In the world of DSL, PPPoE was commonly understood to be running on top of ATM (or DSL) as the underlying transport, although no such limitation exists in the PPPoE protocol itself. Other usage scenarios are sometimes distinguished by tacking as a suffix another underlying transport. For example, PPPoEoE, when the transport is Ethernet itself, as in the case of Metro Ethernet networks. (In this notation, the original use of PPPoE would be labeled PPPoEoA, although it should not be confused with PPPoA, which is a different encapsulation protocol.)

PPPoE has been described in some books as a “layer 2.5″ protocol, in some rudimentary sense similar to MPLS because it can be used to distinguish different IP flows sharing an Ethernet infrastructure, although the lack of PPPoE switches making routing decision based on PPPoE headers limits applicability in that respect.

Nokia #India announces #5G #IoT for #SmartCities

Category : 其他, 技术相关

The Finnish company showcased more than 60 different use-cases of these technologies at its annual Innovation Day in Bengaluru, including those that are already live and ready for use as well as ones that aren’t live yet.

Nokia’s research and development office in Bengaluru, which has around 5,000 employees, creates solutions for both its Indian and international markets. Its new IoT range, though, will focus more on Indian clients, especially governments.

“5G and IoT are going to be the future trends that we see in the marketplace. While from an India standpoint it’s still an early stage for 5G to happen, IoT is taking a bit of a step forward in terms of adoption here,” Randeep Raina, chief technology officer for Nokia India said in an interview on Wednesday.

“There are certain initiatives led by the government right now in the form of digital India and smart city programs. IoT could be one of the enablers to make cities a bit safer and smarter. It’s with that intent that we’d put a theme out here on this innovation day,” he said.

The three main solutions, or use-cases, showcased by the company on Wednesday were video analytics of real-time city surveillance, a public safety service that can be deployed at railroad crossings and a smart parking service.

Based on real-time city surveillance via cameras deployed at various public locations Nokia’s IoT solution will be able to provide clients – mostly governments and policing authorities – with data analysis. The analysis includes everything from identifying anomalies, such as incorrect pedestrian crossings, to tracking traffic patterns.

Its public safety solution uses sensors, beacons and cameras and is aimed at keeping pedestrians from straying across the path of oncoming trains at railroad crossings. This service will both warn people crossing railroads on foot of an oncoming train as well as alert the authorities and issue notice of a fine in case people cross even after receiving a warning. The warning messages will appear on any device using any service provider and are not app-based, i.e. the user will not need to install an app to see the messages.

Nokia’s smart parking solution will target organized parking lots that can use it to fully automate the process – from identifying a car on entry and guiding the driver to free parking spots through an app, to recording the number of hours a car is parked at the lot and bill payment online via the app.

Roughly two months ago, auto components supplier Bosch Ltd also launched solutions targeted at creating smart cities, including a smart parking service that will help commuters find space in crowded areas. The German company has other similar solutions that are, again, aimed at assisting traffic policing and citizen safety and security systems.
