Cyber Millenium

As the basis for communication in the IEC 61850 standard the MMS protocol (manufacturing Messaging specification) for classic client-server communication used WebServices. In addition the proposal was submitted already, to include Web services communication protocol in the standard. Thus, Internet access come as a low-cost alternative in question. WebServices are already a recognized standard (W3C Consortium) and there is a uniform interface description by Web Services Description Language (WSDL). Development and test tools are already available. Opposite the IEC61850 via MMS, WebServices have a lower resource requirements in the control center because there are no permanent connections to build. WebServices of less are also complex, because without ISO/OSI protocols, as well as without ASN. 1 can be used.

It is possible even without third-party (licenses) to integrate in the telecontrol and control technology. Having to build any permanent connection alarm concepts the advantage of WebServices is also with a solution-related Disadvantage of powers. New methods must be found for the rapid transmission of fault information from the DEA. A solution proven in a field test, we present here as Alarm Server “. The concept is necessary because by the cyclic polling of DEA in the minute or every hour fault messages may not can be quickly transferred enough to the control center. Target is the fast forwarding of interfering signals without additional resource requirements in the network control center. The reporting provided for in the IEC 61850 standard is not suitable for this, since it requires a persistent connection to the control centre to the individual DEA. For this reason, the control room itself offers an IEC61850 Server service (alarm-server).

As pending to do this is to integrate a WebService client in the telecontrol gateway of the DEA. A malfunction in a DEA occurs now, she acts as IEC61850 client and uses the WebService Protocol to transmit the fault message to the control center. Communication gateway ACOS 700 in the test in a field test with about a hundred micro 80,0 is the fitness Equipment of communication gateways and the solution on the basis of Web services based on the IEC61850 standard in Germany tested. The fuel cells or even micro 80,0 serve the heating of detached houses and also power supply. The communication gateway ACOS 700 provides the interfaces for maximum of ten energy, gas and heat meters, based on the usual in the counter being M-bus as a wireline solution or wireless MBus, interfaces to the DEA. In addition, the gateway to electric I/O modules for additional information can be added. The remote data can be transferred via Ethernet (for example via DSL, Powerline) or via an internal GPRS module. In addition, the device has over a serial RS232 interface, allowing more peripheral devices can be connected. The focus of the test the suitability of the equipment and the simple integration of the solution into the network control system of multiple energy providers, the network control systems are different Manufacturers operate. Additional properties arising from the usage in private households and the demand after minimal effort for installation and putting into operation, are also in the focus of the field trial. Costs this procedure offers optimized device technology a viable technical solution for the transfer of monitoring and control information between DEA and network control systems of from different manufacturers. To use with the concept, the transmission protocol IEC 61850 via WebServices, opens up the chance for communication, commissioning and integration in the network control technology to keep costs to a minimum.

UHF technology for RFID media for personal identification and in the Auto-ID sector ultimately should depend on all of our needs and technology meet the people. Always interesting to make various reviews and comparisons. Not unfounded anyway, quite high expectations for the UHF technology in the RFID field, which also always again be reformulated. In the identification industry in general look they currently so heavily on logistics in the sense of warehousing and goods control and what medium is possible in the long term in the trade at the article level. Here is a market that can well be occupied by UHF in width. To do that, turns out contactless solutions of the past, that standardization is necessary. Terms such as EPC Gen2, not expert enough to know that he has arrived in the world of products. Specially textiles some interesting things are been pushed on in the last year.

In addition to the “boring” economic considerations there are physical properties in can decide whether the use fits a technology to the problem to be solved and if there is a use case. UHF is just better suited for bridging large distances such as in shipping gates. The pallet identification projects exist at the moment but really high frequency such as UHF solutions side by side. When pilots turned out but also, that several “new” tag simply still too sensitive and to build a more complex antenna configuration for HF prefer. But the good handling of metal and an improved anti-collision but much more use cases for UHF are open, develop.

A quantitative comparison of UHF/RF in the entire market not at the moment in my opinion hardly, also helps in growth rates. Because they are just the projects in the area of ticketing and e-passport, which even longer contribute to large revenues in the HF range and continue to reset. Here, there was a significant increase in the last 2 to 3 years. Many more applications are accessible by HF and just work so that the sales here even could be increased fivefold in the 3-year period. It is already strong and happy the man who would like to see RFID as a whole pushed especially. Somehow fits the current situation for especially UHF but in the theoretical model, because after the hype a consolidation phase should come soon for the first time before device into normal waters, which creates a permanent market and then later step can expand it, also about Auto-ID also. Some even say, you will never reach the market penetration as the traditional RF technologies. Would there be careful and comparing not apples with pears. Without then here offer a vast area fear to take up, tracking, tagging, or certificates of authenticity in our consumerist world. Networking objects of everyday needs required Identmerkmale (vilified by the term “Internet of things”), which should also be thanks to RFID labelling. All mass applications where potentially UHF participate in May and is to a large extent. More research to be an alternative in the vicinity, and these different markets radiate yes even against each other. Correctly is sure that on security-related proximity solutions such as in the area of smart card there is a wide and stable basis for HF, but also companies should address more UHF technology. One must be a prophet so if you want to claim that both RFID technologies will have a longer existence side by side and a topic so, what one well and can move like a year to some omissions.
