Southern Network News (Reporter/Zhang Shuang) makes bus travel smarter and more convenient, leading the future Nansha smart bus command center to adopt Weichuang reverse COB display control system.
Smart bus life
"It takes 15 minutes to get to Hengli subway station from Jiaomen subway station, which is very comfortable!" Passengers of the Nansha G5 road driverless bus have praised it.
G5 road driverless bus is very "smart", such as vehicle-road coordination, just like giving way will "talk", telling the vehicle around the road conditions, including dangerous road section reminders, intersection collision warnings, etc. This information is also displayed in real time on the COB screen of the nansha "smart bus supervision service platform and demonstration line project" command center, and the staff of the center can intervene according to the actual situation to avoid traffic accidents, congestion and other issues.

Demonstration area
Nansha District, the sub-center of Guangzhou City and the Geographical Geometry Center of the Guangdong-Hong Kong-Macao Greater Bay Area, is the "Intelligent Traffic Management Vehicle Networking Demonstration Zone" approved by the Ministry of Communications. In the "Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area", it is also proposed to build an intelligent network demonstration zone and actively serve the construction of an autonomous driving and intelligent transportation demonstration zone.
To this end, in 2021, Nansha District officially launched the "Smart Bus Supervision Service Platform and Demonstration Line Project", which includes a smart bus supervision platform, a smart bus command center, etc., and establishes a smart transportation system with "people-vehicle-road-cloud" collaboration by relying on a new generation of information technology such as big data, artificial intelligence, and vehicle-road collaboration.
Intelligent bus display control system
On the command center of the "Smart Bus Supervision Service Platform and Demonstration Line Project" with an area of 18.4 square meters, the information of 5 bus companies, 814 vehicles, departure completion rate and driving trajectory collected in real time in Nansha District is displayed on a rolling basis, and information interconnection is carried out with staff seats and vehicle terminals.
"Smart Bus Supervision Service Platform and Demonstration Line Project" vertically opens up all levels of the public, enterprises and governments, horizontally realizes business synergy with the competent departments of the transportation industry, builds 7 major applications of vehicle-road collaboration, customized bus, safety management, bus supervision, bus optimization, public service and bus payment, and gathers massive amounts of information in the middle office, this COB display control system needs to have a strong display and transmission control capability to smoothly present this information.
The project adopts Vitron's leading flip-mount COB display control system, which has been running efficiently for more than 9 months after its official opening in July 2021.
Upside-down COB suitable for the Nansha climate
Nansha is located at the mouth of the Pearl River, which is the passage to the sea in Guangzhou, with high temperature, rain and humidity. The flip COB display unit is suitable for this environment in the southern coast, this is because the flip COB has no electrode bonding wire, chip-level packaging, and the surface of the screen body is covered by epoxy resin, which can effectively eliminate erosion such as water vapor and salt spray, and the protection level reaches IP54. Therefore, Hong Kong International Airport, which has a similar climatic environment to Nansha, also adopts The Veron Flip COB Display Control System.

Multiple security guarantees
The smart bus project involves the safety of citizens' lives and property and belongs to the critical information infrastructure, so the project is designed for security protection according to the third level of network security protection. The signal processing of this upside-down COB display control system adopts an embedded pure hardware architecture to effectively eliminate computer virus infestation. The system has the function of automatic service recovery, which can automatically restore the signal status at the end of maintenance, and supports automatically providing fault information alarms for all hardware equipment.
Adapt to smart transportation applications
Weichuang multi-screen processor system processing speed is fast, for each signal dynamically assigned dedicated high-speed transmission channel, RGB signal display speed of 60 frames / second, full-screen refresh speed of less than 0.5 seconds, which enables the driving screen of smart bus vehicles to smoothly hd display, to meet the smart bus daily monitoring, scheduling command and major activities to ensure the synchronous display of the signal window in the scene.
Future-proof open upgrades
The project requires that the current and future vehicle-road collaboration equipment, intelligent network applications and other systems can be open and compatible with each other, and the openness of the COB display control system of Weichuang upside down makes the display control system better integrate with the systems and equipment of the project.
The software and hardware such as "customized bus" and "transportation facilities" in the project will be continuously upgraded in the future, and the display control system has a secondary development interface to meet the new application requirements of project development.
Weichuang has accumulated rich application experience and technology in the field of smart highway transportation, and implemented many influential projects, including Quanxia Expressway, Xinbo Expressway, Beijing-Zhang Expressway, Hebei Traffic Emergency Command Center and Ningbo Bus, etc., to help users realize traffic command, scheduling and decision-making informatization.
Nansha smart bus has unfolded a brilliant scene for us, with the command platform as the brain, all kinds of display control equipment as the eye, and the smart road as the hand... Each element continuously realizes iteration in coordinated operation, and builds a smart transportation system for people to travel conveniently.
