Introduction
As technology advances, economic development and the continuous improvement of people's energy management requirements, community (building and residence) energy demand
(Water, electricity, gas, heat) Collecting and remote management technology into the rapid development stage, the emergence of the first to use various types of communication technology, involving
A variety of products and technology solutions for each 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. This standard is an open system,
It solves the interconnectivity and interoperability requirements. The standard system is divided into several independent part of the development, which is conducive to standard
Itself evolving. This scientific method and the content of the standards are "community energy metering system specification Collecting" national standards mentioned
For 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 there are products demand interconnection, "Collecting community energy metering system Norms" and should be considered with the GB/T 19882 "from
Coordinated move meter reading system ".
The standard system is in the above context developed to recognize this background for understanding the development of ideas and understanding of the standards within this standard
Yung are beneficial.
The standard system includes two aspects of community energy metering Collecting system application management and the underlying communications. In the application management,
The main content is COSEM (Energy metering package specification), the use of object identity and instrument interface object model methods, and thus described
Measuring instruments for remote meter reading and a dedicated application layer. In terms of the underlying communication relates twisted pair baseband (M-BUS) and a short distance without
Line two physical layer, data link layer specification.
In EN1434-3.1997 ( "M-BUS"), with respect to heat meters for the first time introduced based on bus interface physical layer and link layer, twisted pair
Parameters. This section is EN1434-3.1997 part of the update, it is compatible and complement each other. It also includes other measured media
(Water, gas and heat allocation table), the master of communication and the development of newer technologies. Note EN1434-3.1997 also includes other through
Communication technologies.
It can be applied in different application layers, especially the EN13757-3 application layer.
Collecting Community Energy Metering System Specification
Part 2. Physical layer and link layer
1 Scope
This section provides the instrument communication system parameters M-BUS bus interface physical layer and link layer based on twisted pair.
This section applies to heat meters, heat cost allocators, water and gas meter.
General description of the part of the instrument communication systems and remote meter reading, see GB/T 26831.1.
Note. This section also applies to other instruments (such as power meter), sensors and actuators.

4 Physical layer description
4.1 Overview
Figure 1 shows the main electrical physical layer concept. the transmission of information from the host to the station by a voltage level change achieved. use
A (high) voltage level static voltage Umark (idle, typically 36V) and a typical value lower than Umark 12V (at least
12V) dynamic voltage value (space state) for data transmission. High voltage change width increase from the host to the anti-noise station direction
Interference. Minimum voltage needed, can provide continuous power to a remote section of all slaves. Electrical signal transmission through
Pressure changes rather than absolute voltage level to withstand large voltage due to the installation of the cable wire resistance caused by fall. All slaves are connected to the constant current
