Scope: This standard specifies the architecture, basic data definition requirements, data collection requirements, data transmission requirements, information management system construction, functions and security requirements of energy consumption monitoring systems for public institutions. This standard is applicable to the establishment and reconstruction of energy consumption monitoring systems by public institutions.

Introduction

Analysis of the core framework of the standard

This standard constructs a three-level subsystem architecture: on-site measurement and monitoring subsystem, data acquisition subsystem and information management subsystem. Among them, the measurement instruments must meet the accuracy requirements of GB17167, and the data collector must support 32+ device access and have a storage capacity of 256MB.

Comparative analysis of key indicators

Dimensions	Basic indicators	Energy efficiency indicators
Monitoring objects	15 types of energy consumption	29 economic and technical indicators
Data collection	1min-1h adjustable cycle	Sub-item measurement error ≤2%
Transmission security	MD5/SHA encryption	GB/T 22239 Level 3 protection

Typical Implementation Case

A provincial government agency used multi-function electricity meter + ultrasonic water meter to build a monitoring network and achieved data aggregation through the Modbus protocol. After the system is implemented:

Lighting electricity consumption decreased by 27% year-on-year
Air-conditioning system energy efficiency increased by 33%
Data collection completeness rate reached 99.92%

Technology evolution trend

The standard innovatively introduces the ISO/IEC/IEEE18880 ubiquitous green community protocol, supporting:

Multi-protocol compatibility (Zigbee/6LowPAN/BLE)
Tree-like control object model
TRAP event-driven mechanism

Implementation suggestions

Phase 1:Complete the transformation of measuring instruments according to Clause 4.3.1, and the coverage rate of key energy-consuming equipment must reach 100%

Phase 2: Deploy data collectors according to Appendix B to ensure that electromagnetic compatibility complies with GB/T 17626 series requirements

Phase 3: Establish an energy-saving closed loop based on 8.2.7 energy control strategy, paying special attention to the management of special power consumption scenarios
