13.7 Payment_Meter付费表
Payment meters should be specified in terms of the definitions for processes, functions, data elements and interfaces indicated in this technical report. This will cater for all possible variants of single- or multi-part installations. Numerous combinations and variations have already been implemented and new ones will follow in the future.
付费表技术报告中的处理、功能、数据单元和接口的定义来制定规范。应该适合多种可能，独立设备或附用设备。大量的结合和变化已经执行，新的今后也将制定。
Payment meters should conform to the minimum relevant functional requirements for payment meters given in IEC 62055-31.
付费表计应该遵循 IEC62055-31 中给出的最少相关功能需求。
For ease of reference a functional block diagram of a single-part payment meter installation is given in Figure 6, indicating the core functions (see 13.7.1 to 13.7.5) and the support functions (not discussed in further detail).
图六给出了独立付费电表的功能方框图，指出了核心功能（见 13.7.1 到 13.7.5）和支持功能（没有进一步详细讨论）。

It must be noted that a particular component in a payment meter may embody one or more of
these functions and conversely a particular function may be deployed in a combination of
components. There is, therefore, no specific rule to describe the relationship between a function
and an object, which may be: one to one, one to many or many to one.
应注意在付费电表中一个特定的部件可能会用于实现一个或多个功能，反之，一个特定的功能会涉及到很多部件。这样，没有一个明确的规则来描述功能和部件之间的关系，其关系可能是一对一、一对多或多对一。
Functions are linked together by processes in order to achieve a particular result. A particular
macro process may even be comprised of smaller processes or a mix of smaller processes and
functions.
功能是用过程链接在一起的，用于实现一个特定的结果。一个特定的宏过程甚至可能由更小的过程或一组更小的过程和功能组成。
From this perspective the diagram in Figure 7 depicts the core functions and essentially indicates the core processes that are active in a payment meter. The subclauses following give more details on each of these function classes.
图7描述了核心功能，指出了实现付费电表的核心过程。下面的条款对这些功能给出了更详细的描述。
The Charge function and the Credit function are shown in Figure 7 as being separated for the sake of clarity, whereas they are actually sub-class functions of the Accounting function.
Charge功能和Credit功能在图7中是独立的两个功能，这样是为了更清楚，实际上它们是Accounting功能的子功能。
With reference to Figure 7, the generic payment meter application process thus employs the
generic processes 1 to 10 as shown in Table16 below.
根据图7，一般付费电表应用过程包含下表中的过程1到过程10。
