It includes “digital technology, intelligent construction,” “accurate and flexible, intelligent service,” and “panoramic management and control, intelligent operation, and maintenance,” and has formed the whole life cycle technical framework of “intelligent construction, intelligent service, intelligent management, and operation and maintenance.”

1. Introduction

Chongqing East Railway Station is one of the five main stations of Chongqing Railway. It is an important strategic support for Chongqing to integrate into the joint construction of the “Belt and Road,” an important strategic support for accelerating the construction of an inland opening highland, and also an open gateway for Chongqing to consolidate itself in the west, interact with the east, integrate in ASEAN, and connect Asia and Europe. We proposed to build the Chongqing East Railway Station with high quality based on the core concept of “internationalization, greenization, intelligence, and human culture.” Therefore, the “intelligent” technical guidelines of Chongqing East Railway Station building and supporting hub area were compiled [1, 2].

2.2. Compilation System

With the concept of “full life cycle, all-round coordination, and full-function coverage,” this guideline is compiled taking the concept of “internationalization, greenization, intelligence, and human culture” proposed in the “Chongqing City Overall Improvement Action Plan” as the core and comprehensively coordinates the four modernization systems. Combining the stages of the design, construction, and operation and maintenance of the East Railway Station building and the hub area, the whole process is considered. The guidelines are goal-oriented, put forward targeted technical strategies, adopt matrix network analysis methods, clarify specific qualitative and quantitative guidance and control elements, and realize a guideline index system for full-functional object coverage.

Taking the demand model as the starting point and basis, the system model is constructed to organize the relationship, and finally, the physical model is used for material realization (Figure 1). And, organically integrate the transportation hub station with the “railway brain” of the high-speed rail intelligent technology system to build a smart East Station that embodies efficiency and sharing.

5.4.4. Big Data Acquisition Control and Analysis Application

The operation of various electromechanical equipment should be optimized through big data acquisition control and system integration technology control to realize intelligent and energy-saving buildings. In addition, big data analysis applications can be carried out in aspects such as face verification, monitoring management, safety prevention, accident rescue, and dispatching and command [20].

5.5. Smart Energy Management Operation and Maintenance

5.5.1. Achieve Smart Energy Management Platform

It is advisable to adopt an intelligent IoT framework to apply big data, cloud computing, artificial intelligence, machine learning, remote operation and maintenance, and other technologies to the energy management of the East Railway Station to build data collection, edge computing, reverse control, data analysis, and strategy optimization, strategy issuance, and energy forecasting functions. Finally, through the execution and control of energy-saving strategies, big data mining and modeling, and remote analysis and guidance by an expert team, an integrated platform for energy control, management, and operation and maintenance of Chongqing East Railway Station is realized, and energy utilization efficiency and intelligence level are comprehensively improved. [21].

5.5.2. Forming an Information-Based New Energy System

Internet thinking and technology should be used to transform traditional energy sources, to achieve horizontal multisource complementation and vertical “source-network-load-storage” coordination to form a new energy system such as electric energy, solar energy, and geothermal energy with a high degree of information integration at Chongqing East Railway Station.

5.5.3. Smart Grid and Electric Vehicle Management

Apply smart grid and manage electric vehicles in Chongqing East Railway Station. Smart grids can access energy data and provide new pricing plans to improve energy efficiency. Electric vehicles acting as power storage equipment can provide emergency power for the East Station.

5.5.4. Self-Regulating Energy Management System of Blockchain Technology

With the BS-EMS node as the physical foundation and the energy quota as the digital medium, it provides a solution for mutual trust between smart devices. It is advisable to establish a trustworthy energy value network for each node in the energy management system and realize the independent regulation of the energy system. Within 10–30 minutes, BS-EMS should allocate energy quotas for 3–5 energy consumption cycles to energy-consuming nodes to maintain network fault tolerance.

6. Conclusion

This paper expounds the research conclusion of “intelligent” technology guidance for railway transportation hub station. At the same time, the planning principles, control points, and design methods of design, construction, operation, and maintenance are found. In the future, it is necessary to conduct qualitative and quantitative research on the intelligent technology of transportation hub [22].
