Foreword

GB/T 26831 "Community Energy Metering Recycling System Specification" consists of the following six parts.

- Part 1. Data exchange;

- Part 2. physical and link layers;

- Part 3. Dedicated application layer;

- Part 4. Wireless reading of instruments;

- Part 5. Wireless relay;

- Part 6. Local bus.

This part is part 4 of GB/T 26831.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

With the scientific and technological progress, economic development and people's energy management requirements continue to improve, the community (construction and residential area) measurement (water, Electricity, gas, heat) remote copy and management of technology applications into the rapid development stage, the emergence of a number of use of various types of communication technology, involving each Measurement of a variety of products and technical solutions. Product manufacturers and users are eager to see these products or systems to be unified standard.

Thus, since 1999, the International Electrotechnical Commission has issued the IEC 62056 "meter reading, rate and load control data exchange" Series of standards; domestic reference to its content issued a GB/T 19882 "automatic meter reading system" series of standards. The standard is an open system, A good solution to the interconnection and interoperability requirements. The standard system is divided into relatively independent parts to develop, which is conducive to the standard Its own continuous development. This scientific method and the contents of the standard are GB/T 26831 "community energy metering system regulations" system Will provide a good reference.

At the same time, due to obvious reasons, the community energy metering system and automatic meter reading system has many similar or common content, The reality of the product also has the needs of interconnection, GB/T 26831 "community energy metering system specifications" to consider and GB/T 19882 "automatic meter reading system" coordination.

GB/T 26831 It is in the above background to develop, understand this background to understand GB/T 26831 the development of ideas and understanding Standard content is useful.

GB/T 26831 contains the contents of the application management and the underlying communication in the community energy metering system. In the application management side Surface, the main content is COSEM (energy measurement supporting norms), the use of instrumentation object identification and interface object method to establish a model, and further A dedicated application layer for meter and remote meter reading. In the case of the underlying communication, a twisted pair baseband (M-BUS) and a short pitch are included From the wireless two physical layer, the link layer specification.

1 Scope

This part of GB/T 26831 specifies the parameter requirements for the physical and link layers of the remote wireless meter system.

This part applies to the use of free license 433MHz ~ 434MHz wireless civilian band and 470MHz ~ 510MHz measurement frequency Segment of the "short distance device" (SRD), covering portable devices, mobile devices and fixed equipment.

Since there is a broad definition, this section can be used for different application layers.
