28、 62055-31:2005 INTRODUCTION Payment meters are used in situations where the supply of electrical energy to the load may be interrupted or its restoration enabled under the control of the payment meter in relation to a payment tariff agreed between the customer and the supplier. The payment meter is

29、part of a system that uses token carriers to pass payment information as tokens between a vending network and the payment meters that include the meter accounting process. The functions of a payment meter are to measure electrical energy consumed and to decrement the available credit value in accord

30、ance with the metered consumption, and possibly in accordance with the passing of time. This available credit value is incremented as the result of payments made to the electricity supplier, and the meter accounting process continuously calculates the balance of available credit held by the customer

31、 When the available credit value has been decremented to a predetermined value that is related to the payment mode in use, a switch is used to interrupt the supply to the customers load. However, additional features may be present in the payment meter, which prevent or delay the opening of the swit

32、ch, or limit further consumption to a low load level. Such “social” features may include the provision of an emergency credit facility, the possibility of operation in a fixed-payment mode, and the inhibiting of interruptions for certain periods of time. In return for the payment (usually in cash) a

33、nd depending on the particular type of system, the customer may be issued with a single-use token on a disposable token carrier for the equivalent value, or a reusable token carrier may be credited with that value, or the token may be transmitted directly to the meter via a communications network (a

34、 so-called virtual token carrier). “One-way” and “two-way” data transfer systems may be used, and the token carriers may be: physical devices such as smart cards, or other electronic devices, or magnetic cards; virtual token carriers where the token information is transferred by a remote communicati

35、ons system; or numeric token carriers where sequences of digits are issued on a paper receipt and entered via a keypad on the meter. IEC 62051 provides some details of payment metering terminology in Clause 17. Licensed Copy: Wang Bin, na, Tue Apr 25 02:01:05 BST 2006, Uncontrolled Copy, (c) BSIEN 6

36、2055-31:2005 6 ELECTRICITY METERING PAYMENT SYSTEMS Part 31: Particular requirements Static payment meters for active energy (classes 1 and 2) 1 Scope This part of IEC 62055 applies to newly manufactured, static watt-hour payment meters of accuracy classes 1 and 2 for direct connection, for the meas

37、urement of alternating current electrical energy consumption of a frequency in the range 45 Hz to 65 Hz that include a load switch for the purpose of interruption or restoration of the electricity supply to the load in accordance with the current value of the available credit maintained in the payme

38、nt meter. It does not apply to static watt-hour payment meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems). It applies to payment meters for indoor application only, where the payment meter shall be mounted as for normal ser

39、vice (i.e. together with a specified matching socket where applicable). Payment meters are implementations where all the main functional elements are incorporated in a single enclosure, together with any specified matching socket. There are also multi-part installations where the various main functi

40、onal elements, such as the measuring element, the user interface unit, token carrier interface, and the load switch are implemented in more than one enclosure, involving additional interfaces. This part of IEC 62055 does not apply to multi-part payment metering installations. Functional requirements

41、 that apply to payment meters are also defined in this part of IEC 62055, and include informative basic functional requirements and tests for the prepayment mode of operation in Annex A. Allowances are made for the relatively wide range of features, options, alternatives, and implementations that ma

42、y be found in practice. The diverse nature and functionality of payment meters prevent the comprehensive specification of detailed test methods for all of these requirements. However, in this case, the requirements are stated in such a way that tests can then be formulated to respect and validate th

43、e specific functionality of the payment meter being tested. This part of IEC 62055 does not cover specific functionality or performance requirements for safety, circuit protection, isolation or similar purposes that may be specified through reference to other specifications or standards. This part o

44、f IEC 62055 does not cover software requirements. Software requirements for basic energy meter metrology are under consideration for the IEC 62059 series of standards, and in other organisations. This part of IEC 62055 covers type-testing requirements only. For acceptance testing, the concepts given

45、 in IEC 61358 may be used as a basic guideline. Dependability aspects are addressed in the IEC 62059 series of standards. This part of IEC 62055 does not cover conformity tests and system compliance tests that may be required in connection with legal or other requirements of some markets. Licensed C
