34、s communications capabilities. The following sections detail the variations of functional complexity that are likely to make up smart meters or may form part of a smart metering system. The table below details some of the possible aims and methods that may form part of a smart meter. Table 1 Aims an

35、d methods for smart meters Aim Means Possible methods Reduction of costs for meter reading (in case frequent meter reading is obliged) Remote meter reading Minimum one way communication from meter Reduction of complaints improved quality of meter reading Remote meter reading Minimum one way communic

40、that required by the MID2). It is worth noting the quotations from MID Annex 1, “Essential Requirements“ that are contained in Annex A of this document. It can be argued that prepayment meters that provide data back to the suppliers IT systems via a token are Smart. To try to clarify the different t

41、ypes of meter that are available, different categories are defined below. 3.3 Basic meter with output of pulses or data 3.3.1 General A basic meter with output can be part of a smart (AMR) system. It may be possible for this system to meet the recommendations of ESCO. 3.3.2 Pulse output The basic me

42、ter may have an integrated or a remotely equipped pulse output or a data output. The pulse is widely used as a method of providing data from a meter. The meter emits a pulse each time a fixed volume is measured. The pulse value outputs are marked as 1 imp m (or dm) or 1 m (or dm) imp. The most widel

43、y used method for pulse output is to use a magnet in one of the least significant wheels in the index. A reed switch is commonly used to detect the passage of the magnet. 3.3.3 Data output Data outputs can be provided through serial interfaces. Data outputs should provide information on meter readin

44、gs, meter identification and meter status. The index value (as read on the meter) is provided by the data output. Data outputs can be built-in or provided by add-on to an existing meter. Depending on the interface used, data encryption and access control has to be considered. Guidance on data output

45、s is detailed in WELMEC Software Guides 7.1 and 7.2. 2) Please note that meters with pre-MID approvals will also usually meet this recommendation. PD CEN/TR 16061:2010CEN/TR 16061:2010 (E) 10 3.4 AMR meter An Automatic Meter Reading (AMR) meter can form part of a smart metering system. An AMR-equipp

46、ed meter can provide data to an IT system. In its simplest form, it provides a current meter read without physical access to the meter. A number of technologies exist that can be used to collect and transfer the data from inductive pad, where a meter reader needs to physically connect a reading devi

47、ce to a component connected to the meter, through walk-by and drive-by systems, to fixed wired or wireless networks with star or mesh topologies. An AMR system can be built based on a basic meter with pulse or data output. An AMR meter may or may not log data, and provide information about events3)a

48、nd its status when it transmits data. While it is possible for an AMR Meter to be truly one way, broadcasting data either continuously or at pre-set intervals, most systems are at least 1,5 way (which report when stimulated), and many are two way, and give answers to specific questions. 3.5 Prepayment meter Prepayment, or “pay as you go“, meters allow customers to make advanced payment for energy4). In their simplest form, a mechanical token (or coin) is used to allow the valve within the meter to be opened until a measured quantity of gas has been consumed. State of the art prepa
