Project Implementation

项目实施

The implementation of this project follows a systematic path of "Top-Level Design - Pilot Verification - Network-Wide Promotion", advanced in a structured manner as follows:

1.System Construction and Standard Development Phase

First, focusing on the core challenges of energy consumption management in Chengdu Metro’s ultra-large network and the core requirements for green development, a cross-departmental (inter-unit) special team was established. The team conducted full-chain energy consumption audits and data analysis on 12 categories and 37 types of key electrical equipment, formulated the Energy Conservation Plan for Each Station, and developed differentiated and operable phased measures. These efforts provide an institutional basis for refined energy conservation management at the network level. Meanwhile, to address the current issue of inappropriate temperature in metro stations, in accordance with the group’s internal deployment for smart station construction, research on the "Dynamic Human Thermal Comfort Standard Adapted to Chengdu’s Environment" and research on AI-enabled smart stations were launched.

本项目实施遵循“顶层设计——试点验证——线网推广”的路径，系统性推进：

一、体系构建与标准研制阶段：首先，聚焦成都地铁超大线网能耗管理的核心挑战与绿色发展的核心要求，组建跨部门（单位）专项团队，对12类37种主要用电设备进行全链路能耗审计与数据分析，形成《节能一站一策》，制定差异化的、可操作的分阶段措施，为线网级精细化节能管理提供制度依据。同时，针对目前地铁车站温度不适宜的现实问题，落实集团内部智慧化车站建设的部署安排，启动“适应成都环境的人体动态热舒适度标准”研究和AI智慧车站研究。

2.Sample Selection and Technical Breakthrough Phase

Dayuan Station and Wuhouci Station were selected as pilots to build benchmark samples of green low-carbon stations and smart stations respectively.

Dayuan Station (Green Low-Carbon Model): Guided by the goal of meeting citizens’ comfortable temperature range, precise adjustments were made to the station’s ventilation and air conditioning system. The key strategies include: reducing the operating frequency of fans in the main ventilation system, implementing the energy-saving mode for main system ventilation, adjusting the "micro-positive pressure" of supply and exhaust air volume in the main system, optimizing the outlet temperature of chilled water, and defining the activation conditions for the cooling source system.

Wuhouci Station (AI Smart Benchmark): Driven by scenario-specific needs, and based on 30 smart application requirements of the metro (including automatic station opening/closing, intelligent construction supervision, services for passengers with special needs, detection of abnormal passenger behaviors, and digital emergency plans), the station accurately identified business pain points and restructured traditional business processes. With the digital and intelligent base as the core support platform for the project, technologies such as cloud computing, the Internet of Things (IoT), big data, and artificial intelligence were integrated to provide strong data support and intelligent analysis capabilities for station operations.

二、样本选择与技术攻坚阶段：选取大源站和武侯祠站作为试点，打造绿色低碳与智慧车站样本标杆。

大源站（绿色低碳样板）：以市民舒适温度区间为思路，对车站通风空调进行精调，主要策略是降低大系统风机运行频率、执行大系统通风节能模式、调整大系统送排风量“微正压”、调整冷冻水出水温度、限定冷源系统开启条件等。

武侯祠站（AI智慧标杆）：以场景化需求为导向，结合地铁包含自动开关站、智能施工监管、特殊乘客服务、乘客异常行为感知及数字应急预案等30项智慧应用需求，精准识别业务痛点，重构传统业务流程。以数智底座作为项目核心支撑平台，融合云计算、物联网、大数据和人工智能等技术，为车站运营提供强大的数据支撑与智能分析能力。

3、Ecological Integration and Network-Wide Promotion Phase

In line with the actual situation of Chengdu Rail Transit, the "Rail + Public Transport + Active Transport" green travel system was proposed as a strategic initiative. While continuing to tap potential in energy conservation and emission reduction, and advancing technological innovation for quality and efficiency improvement, the "Green Network Weaving Initiative" was simultaneously carried out to actively cultivate a green travel culture. Efforts were made to convert technological advantages into citizens’ travel habits, and the hierarchical management and control measures were promoted across the entire metro network.

三、生态融合与线网推广阶段：结合成都轨道交通实际，战略提出“轨道+公交+慢行”绿色出行体系，在持续深入挖潜节能减排、提质增效的科技创新过程中，同步开展绿色织网行动，积极培育绿色出行文化，将技术优势转化为市民的出行习惯，并在全线网推广分级管控措施。

Project Impact & Sustainability

项目影响力、可推广性与可持续性

Project Influence:The "Rail+Public Transport+Active Transport" green travel structure will enhance the synergy of the city’s green and low-carbon transportation network, helping Chengdu build itself into an international comprehensive transportation hub city. Metro AI smart stations represent an important practice in the construction of "Smart Rongcheng" (Chengdu’s smart city initiative), providing a model for the intelligent operation and management of rail transit in cities with ultra-large-scale transit networks. Hierarchical energy conservation management and refined equipment governance will significantly reduce the operational energy consumption of Chengdu Metro’s ultra-large network, establishing a benchmark for green development in the industry. Research on human thermal comfort regarding station temperatures can simultaneously promote the dual improvement of low-carbon standards and passenger experience, enhancing citizens’ sense of identification with green travel and their sense of well-being.

Promotability & Sustainability: The project covers multi-dimensional innovations in "technology-management-service". Technical solutions such as the hierarchical energy conservation model and the AI intelligent agent platform will have the potential to be adapted to urban rail transit systems of different scales. The human thermal comfort standards and green travel system have regional expansion potential, which can provide references for cities in the same climate zone. The project as a whole will be applied in a wider range of practices, operating in the long term and adapting to future energy policies and technological development trends.
