9moon22to24on the 16th, the 16th international transportation technology and equipment exhibition, hosted by the ministry of transport, was held in beijing shougang park. the theme of this exhibition was to create“people enjoy their journey and goods flow freely”a beautiful vision. when visiting the exhibition, the reporter found that new technologies including the online coupling and uncoupling system for subway cars, shared electric bicycles, and lane-level pilot functions will make green travel more environmentally friendly and easy.

after the opening of line 3,4、8mixed running of trains

what does a "smart subway" look like? in the "green transportation and energy transformation exhibition area", a series of leading smart subway technologies were described in detail to the audience.

"with the advancement of large-scale and networked rail transit operations, we are facing new challenges of mismatched transport capacity and transportation capacity, and the limitations of traditional fixed train formations are becoming apparent," said wang xiaoyong, general manager of casco's urban rail product center.3line 1 will be the first to apply flexible marshaling technology in a fully automatic line. it can realize unmanned operation of the whole process of train coupling and uncoupling in multiple scenarios such as vehicle bases, mainline return lines and parking lines, and station platforms according to passenger flow characteristics or emergency needs.2configuration switching is completed within minutes.

based on this technology,3after the completion and opening of line 1,4section grouping,8the ability of "mixed running" of section-marshaled trains can maintain a small interval between runs during off-peak hours, reducing passengers' waiting time on the platform, improving the quality of operational services while achieving energy conservation and emission reduction.

shared electric bicycles make riding easier

green travel can also be labor-saving. at the didi booth, a new shared electric-assisted bicycle attracted the attention of many visitors. although it is powered by electricity, it is much lighter than ordinary electric bicycles in appearance. its battery is "hidden" in the diagonal beam, and a helmet is placed in the basket. riders can use the helmet by scanning the code to unlock it.

“this shared electric bicycle, which debutedEM2.0equipped with lightweight batteries and power sensors, it can accurately sense the rider's pedaling force and frequency, and activate the intelligent power system to assist riding. after the user pedals three circles, the electric power will automatically intervene, making the user's riding easier and more labor-saving. "didi qingju's industrial design expert chen qing introduced that the vehicle is also equipped with front hydraulic shock absorbers and one-piece die-cast wheels, which can greatly improve riding comfort and stability. at the same time, the electric power bicycle has a range of35for every kilometer, the operating company will set up its own charging cabinet, and the operation and maintenance personnel will charge the vehicles in a timely manner.

lane-level navigation puts drivers in the fast lane

at this transportation exhibition, amap launched the world's first lane-level navigation function on a map platform, providing car owners with faster lane recommendations.

it is reported that the biggest feature of lane-level pilot is that it realizes“beyond visual range”perception, can see farther than the naked eye, and is not limited by physical components such as sensors.“penetrate”surrounding vehicles, help users“see”the function is currently gradually covering highways and urban expressways in cities across the country, including beijing.

at the same time, amap has launched a satellite distress call function for users who may be traveling, hiking or exploring in areas without signals, roads or even uninhabited areas. when users enter a roadless area, amap will prompt them to record their footprints throughout the journey, and when returning, they can choose to return along the original route. if they encounter danger on the way, the satellite distress call function can also send out effective distress messages with precise positioning, so that rescue forces can know the exact location and trajectory of the rescuer, greatly improving rescue efficiency. whether there is a network signal or not, the satellite distress call function has covered it.
