Chongqing Jiangtiao Line Dual Current System Vehicle
The dual current system vehicle of Chongqing Jiangtiao Line is based on the existing mature As type vehicle, and the car body, front end, coupler, gangway, interior decoration, auxiliary, lighting, passenger compartment electrical, passenger information and other parts refer to the latest technical scheme of Chongqing As type vehicle; Bogie, traction, high voltage, braking, network, door, air conditioning and other systems are improved on the original basis to meet the requirements of high speed level. Based on the technical support of the first dual current system A-type urban vehicle in China, the basic principle and some components of the AC-DC switching system of the dual current system A-type urban vehicle platform are used for reference, and the fault and rescue conditions after the failure of AC-DC switching are demonstrated, and the specific solutions are put forward. The dual current system vehicle with Chongqing Jiangtiao Line has the following characteristics: ① it is equipped with two power supply systems of AC and DC; ② automatic AC/DC switching without stopping or lowering the bow; ③ it is interconnected and interoperable; ④ it is safe, reliable, intelligent, advanced, comfortable and environmentally friendly. The 1:10 vehicle model site is 10 meters long and 1 meter wide, with a load of 100 kilograms.
Intelligent Inspection Robot System for Chongqing Jiangtiao Line Urban Rail Vehicles
The intelligent inspection robot system (in kind) for Chongqing Jiangtiao Line Urban Rail Vehicles and the intelligent train inspection integrated detection system for urban rail vehicles have been applied in the field of Chongqing Jiangtiao Line. The system adopts cutting-edge technologies such as intelligent robot technology, SLAM autonomous navigation technology, multi-degree-of-freedom flexible cooperative manipulator control technology, high-definition optical imaging technology, parallel structured light three-dimensional imaging technology, image pattern recognition technology and AI deep learning algorithm to accurately image the key maintenance points of train inspection under the vehicle and intelligently judge the abnormal state of key components under the vehicle.
The site needs to provide a demonstration site for robots, with an area of about 3 square meters, length, width and height: 2m * 1.5 m * 3m; there is an AC220V charging power supply near the booth. Weighing 400 kg

To build a bridge and link of "four networks integration" and create a multi-level rail transit network with clear levels, precise functions, and reasonable layout, under the firm leadership of the Chongqing Municipal Committee, the Municipal Government, and the Municipal SASASAC, and with the strong support of the relevant departments at the municipal level. Chongqing City Transportation Development & Investment Railway Group fully docks with the national comprehensive three-dimensional transportation network planning outline, Chengdu-Chongqing economic circle multi-level rail transit planning, Chongqing comprehensive three-dimensional transportation network planning outline, Chongqing comprehensive transportation "14th Five-Year Plan" and Chongqing urban rail transit construction "14th Five-Year Plan", and optimizes and adjusts the Group's development plan in time, planning ahead and taking the initiative. Based on the "trinity" development pattern of network construction, intelligent operation, and diversified operation, the integrated urban express network system of "urban (suburban) railway+urban rail express line" is planned and laid out in advance, that is, the four "two vertical and two horizontal" urban railways connecting the central urban area, 260 kilometers of urban rail, express line and 11 lines “one ring and ten shots”, and 1,161 kilometers of urban (suburban) railways in the new area of the main city have carried out the exploration of diversified investment and financing modes. The first set of express line standard systems and dual current system technical specifications in China have been issued. A digital construction and management platform based on BIM technology has been built, which has consolidated the foundation of high-quality development of the Group, promoted the urban express line industry into the "fast lane", and stepped onto a new starting point of becoming bigger and stronger and creating brilliance again.

BIM (Building information modeling) technology is an information integration and management technology based on three-dimensional building model, which can realize the informatization and visualization management of engineering objects in various stages of rail transit construction, realize the transformation from two-dimensional drawings to three-dimensional models, reduce engineering changes and improve engineering predictability. At the same time, the information in the design and construction stages is seamlessly used in the operation and maintenance management to improve the management level of the whole life cycle of the project, ensure the construction period, reduce costs, reduce waste, and maximize the benefits of asset operation.

Since April 2018, the main leaders of the Chongqing Railway Group have personally deployed and planned to explore the application of digital construction management based on BIM. Based on the technical policy of "unified leadership, unified planning, unified standards, unified resources, and unified management", and following the technical standards of "advanced, mature, economic, applicable, and reliable", a digital construction and management plan for the whole life cycle of express line network based on BIM with the goal of the operation has been formulated, and BIM technology has been compiled and issued. Strengthen the digital dynamic management of project progress, investment, safety, quality, and other aspects, establish the BIM + construction and management application collaboration center of the express line, gather the strength of all participating units, and comprehensively promote the visual project management based on BIM, the information management of land acquisition, demolition and pipeline relocation based on GIS technology, and the safety based on intelligent site construction. Continuously improve the quality and management level of urban express line construction, and strive to explore the application path of BIM application + enterprise informatization + GIS (geographic information system) in the whole life cycle of the project.
