--- Replace IEC 62497-1:2010 (see 4.3.8.2, 4.3.8.3) with the normative reference GB/T 32350.1-2015 to adapt to our the technical conditions of the country increase operability.

The following editorial changes were made to this document.

--- Deleted the VIN European format description (see 3.1.21 Note 1 of IEC 62888-1:2018);

--- Deleted the CPID European format description (see 4.2.5.2 Note 1 of IEC 62888-1:2018);

--- Changed the safety guide description, changing "European country related guidelines EN50155, EN45545-2 and EN45545-5" to "Refer to relevant fire protection requirements of EN45545-2" (see Note 2 of 4.2.6.4, Note 1 of 4.2.6.4 of IEC 62888-1:2018).

Introduction

Energy efficiency is essential to meet the challenges of supporting energy policies, protecting the environment and conserving natural resources.

Energy efficiency, especially the standardization of overall energy efficiency of rail transit vehicles, has attracted great attention from the rail transit industry, and relevant standards are being gradually formulated.

The main contents include the definition and boundary of energy efficiency, influencing factors, test methods, etc. GB/T 44639 "Electric Vehicles for Rail Transit" the Energy Measurement System is designed to standardize the process of acquiring train power data and ensure the reliability of the data. It consists of six parts.

--- Part 1: General. The purpose is to specify the system-level requirements of the energy measurement system and to implement one or more General requirements for equipment with multiple functions.

--- Part 2: Electric energy measurement. The purpose is to specify the requirements for electric energy measurement functions for measuring the electric energy consumed and regenerated by traction units, and Requirements for the voltage measurement function, current measurement function and energy calculation function that make up the energy measurement function.

--- Part 3: Data processing. The purpose is to specify the data processing system and ground data collection service in the electric energy measurement system requirements.

--- Part 4: Communications. The purpose is to specify the requirements for on-board data communication services and vehicle-to-ground communication services of the energy measurement system.

These communication services enable data to be transferred between functions within the energy measurement system, between the energy measurement system and other on-board units, and between data Handles exchanges between the system and ground servers.

--- Part 5: Conformance test. The purpose is to specify the consistency test of new energy measurement systems installed on traction units Arrangements, and conformance testing procedures for replacement of equipment and auxiliary components.

--- Part 6: Requirements other than billing. The purpose is to clarify the requirements for energy consumption benchmark testing, daily energy consumption monitoring, and technology research and development.

Able to measure the specific requirements of the system.

The functional structure, main sub-functions and data flow of the train power measurement system are shown in Figure 1.
