Their preparation is entrusted to

16、 technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International

17、 Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each tec

18、hnical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Pub

19、lications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their na

20、tional and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to

21、 be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Commi

22、ttees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to

23、 the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication.

30、vised edition, or amended. A bilingual version of this publication may be issued at a later date. 62055-51 IEC:2007(E) 5 INTRODUCTION The IEC 62055 series covers payment systems, encompassing the customer information systems, point of sales systems, token carriers, payment meters and the respective

31、interfaces that exist between these entities. At the time of preparation of this part, IEC 62055 comprised the following parts, under the general title Electricity metering Payment systems: Part 21: Framework for standardization Part 31: Particular requirements Static payment meters for active energ

32、y (classes 1 and 2) Part 41: Standard transfer specification Application layer protocol for one-way token carrier systems Part 51: Standard transfer specification Physical layer protocol for one-way numeric and magnetic card token carriers Part 52: Standard transfer specification Physical layer prot

33、ocol for a two-way virtual token carrier for direct local connection The Part 4x series specifies application layer protocols and the Part 5x series specifies physical layer protocols. The standard transfer specification (STS) is a secure message protocol that allows information to be carried betwee

34、n point-of-sale (POS) equipment and payment meters and caters for several message types such as credit, configuration control, display, and test instructions. It further specifies devices and codes of practice that allow for the secure management (generation, storage, retrieval and transportation) o

35、f cryptographic keys used within the system. The national electricity utility in South Africa (Eskom) first developed and published the STS in 1993 and transferred ownership to the STS Association in 1998 for management and further development. Prior to the development of the STS a variety of propri

36、etary payment meters and POS equipment had been developed, which were, however, not compatible with each other. This gave rise to a definite need among the major users to move towards standardized solutions in addressing operational problems experienced where various types of payment meter and POS e

37、quipment had to be operated simultaneously. An STS was developed that would allow for the application and inter-operability of payment meters and POS equipment from multiple manufacturers in a payment metering installation. The TokenCarrier is the physical device or medium used to transport the info

38、rmation from the vending system to the payment meter. Two types of token carriers are specified in this part of IEC 62055, a magnetic card and a numeric token carrier, which have been approved by the STS Association. New token carriers can be proposed as new work items through the National Committee

39、s or through the STS Association. Although the main implementation of the STS is in the electricity supply industry, it inherently provides for the management of other utility services like water and gas. Future revisions of the STS may allow for other token carrier technologies like smart cards and

40、 memory keys with two-way functionality and to cater for a real-time clock and complex tariffs in the payment meter. The STS Association has established a D-type liaison with working group 15 of IEC TC 13 for the development of standards within the scope of the STS and is thus responsible for the ma

41、intenance of any such IEC standards that might be developed as a result of this liaison. The STS Association is also registered with the IEC as a Registration Authority for providing maintenance services in support of the STS (see Clause C.1 of IEC 62055-41 for more information). 6 62055-51 IEC:2007

42、(E) ELECTRICITY METERING PAYMENT SYSTEMS Part 51: Standard transfer specification (STS) Physical layer protocol for one-way numeric and magnetic card token carriers 1 Scope This part of IEC 62055 specifies a physical layer protocol of the standard transfer specification (STS) for transferring units

43、of credit and other management information between a point-of-sale (POS) system and an STS-compliant electricity payment meter. It specifies encoding of token data onto token carriers in the physical layer protocol at the POS for various TokenCarrierTypes such as numeric and magnetic cards; decoding

44、 of token data from token carriers in the physical layer protocol at the payment meter for various TokenCarrierTypes such as numeric and magnetic cards. It is intended for use by manufacturers of payment meters that have to accept tokens that comply with the STS, and also by manufacturers of POS sys

45、tems that have to produce STS- compliant tokens, and should be read in conjunction with IEC 62055-41. NOTE 1 Although developed for payment systems for electricity, the standard also covers tokens used in other utility services, such as water and gas. NOTE 2 STS-compliant products are required to co

46、mply with selective parts of this International Standard only, which should be the subject of the purchase contract (see Annex A). 2 Normative references The following referenced documents are indispensable for the application of this document.
