Introduction

As technology advances, economic development and the continuous improvement of people's energy management requirements, community (buildings and residential areas) metering (water, Electricity, gas and heat) of the Collecting and remote management technology into the rapid development stage, the emergence of the first to use various types of communication technology, involving various A variety of products and technical solutions in the field of metrology. Product manufacturing side and the user side is eager to these products or systems to follow uniform standard. Thus, since 1999, the International Electrotechnical Commission have published the IEC 62056 "Data exchange for meter reading, tariff and load control" Series of standards; the development of the country with reference to their published content GB/T 19882 "automatic meter reading system" series of standards. GB/T 19882 is open System, a good solution to the interconnectivity and interoperability requirements, the standard system is divided into several independent part of the development, which will help The continuous development of the standard itself. Contents of this scientific method and GB/T 19882 are both "Collecting Community Energy Metering System Specification" national standard Prospective development provides a good reference. At the same time, for obvious reasons, community energy metering and automatic meter reading system meter reading system has many similar or common content, In reality the product will be in demand interconnection, "Collecting community energy metering system Norms" and should be considered with the GB/T 19882 "from Coordinated move meter reading system ". GB/T 26831 It is in the above context developed to recognize this background understanding of GB/T 26831 to develop ideas and understanding Standard content are beneficial. GB/T 26831 contains two aspects of community energy metering Collecting system application management and the underlying communications. Managing Application Surface, the main contents of COSEM (Energy metering package specification), the use of object identity and instrument interface object model methods, and thus description Said a dedicated application layer for measuring instruments and remote meter reading. It relates to the underlying communications include twisted pair baseband bus system (M-BUS) and regulate the short-range wireless communication system, two physical layer, data link layer. GB/T 26831.6 multiple link layer and application layer can be used. Typically, using GB/T 26831.3 (M-Bus) dedicated DLMS based application layer in the application layer or GB/T 26831.1 described. GB/T 26831.1 outlined meter communication system, which also contains further definitions. Collecting Community Energy Metering System Specification Part 6. Local Bus

1 Scope

This section GB/T 26831 requirements, a battery-powered single-copy reading device ( "master") and a single instrument or group of instruments (most Communications read or copy copy local meter reading system, mostly 5) between ( "Local Bus") physical layer parameters. "Master" can temporarily or Perseverance directly connected to the instrument (ie. local copy to read), but also the total length of the fixed-line or via a small bus connection meter (maximum cable 50m, namely. a local copy of a remote reading). About instrument communication systems and remote meter reading copy of general statements, see GB/T 26831.1.

Physical layer and link layer

3 physical layer specifications

Local bus is a variant of the M-Bus bus. Its application is limited to small devices (in line with GB/T 26831.2-2012 Appendix E.6.1 The E-type Minibus device), and for the pure battery-powered device optimized master. Typically, the copy read by the frequency meter constraints. this Bus does not support instruments to take power from the bus. Note that this instrument interfaces and comply with GB/T 26831.2-2012 the M-Bus master is not Compatible. To facilitate instrument power management, master should be turned on bus power not exceeding 10s time before starting any communication instruments (ie. Sent into the master reference state), see Table 2 in the "master label status before communication duration." Note. Appendix A circuit diagram is a possible solution to achieve this interface. The instrument has a local bus interface should meet the requirements of Table 1. Table 1 meter requirements Parameter Minimum Maximum No damage to the instrument voltage > ± 50V - Ground insulation > 1MΩ - Meter mark state receives a voltage> ± (UAM-1V) < ± 15V Meter space state receives a voltage 0V < (UAM-3V) Send current meter mark state (IBM) 0.5mA = 1LUL (LUL.
