COB LED ultra-high-definition + curved large screen lights up a rail transit

Recently, the large LED ultra-high-definition display screen in the rail transit center was officially put into use. Its unique curved design perfectly integrates the utilization of space and the smoothness of the picture, and complements each other.

In recent years, major cities in China have vigorously promoted the construction of urban rail transit. However, the types of information generated in the life cycle of urban rail transit are complex, diverse, huge in quantity, information loss, poor or untimely information communication, and the ubiquitous phenomenon of “information fragments and information islands”, etc., to a large extent Restricted the efficiency of construction management. However, the existing information management methods generally can only play the role of auxiliary management, and cannot achieve a fundamental improvement in management level.

LED ultra-high-definition large screens use multiple sets of COB LED display systems, using COB integrated packaging technology, with high reliability (extremely low out-of-box dead pixel rate, long trouble-free use time), high contrast, high color gamut, high Refresh rate and other technical advantages. This rail transit large screen adopts a unique curved design, which perfectly presents a smoother, faster, and more colorful display effect, and provides ultra-high-definition display services.

In addition, the COB ultra-high-definition visualization system can also build a digital command and control center for urban rail transit, display important information such as driving, power, environmental control, automatic fare collection, video images, and operation organization in real time, and fully control the operating status of the rail transit system.

According to user needs, it is displayed in different regions:

Area 1 is mainly based on the comprehensive summary information of line network traffic, electricity, passenger flow, video, major events, etc. It can display ATS information of multiple lines at the same time, and can switch to the emergency display screen if necessary, such as line traffic involving emergency events , traction power supply, distribution of emergency facilities, etc. It is necessary to realize the calling of different modes and scene screens.

In area 2, the network video surveillance screen mainly monitors operation video surveillance information and public security video surveillance information. Dispatchers need to monitor the station, passenger flow in the car, and passengers getting on and off the bus in real time to ensure safe, fast, and punctual operation; In the event of an emergency (such as fire, anti-terrorism, natural disasters, etc.), real-time images of the scene are provided to relevant personnel to facilitate on-site rescue and passenger guidance.

Area 3 focuses on the network power dispatching splicing display to display professional systems, such as: environmental control system, power supply system, disaster prevention system, main control system, etc. The emergency command display area is mainly composed of lines involving emergency events, traction power supply, distribution of emergency facilities, etc., and other display areas are required to provide real-time image information on the scene of emergencies.

Information Sharing

Unified access and scheduling of CCTV multi-channel video signals, RGB signals, computer information, digital streaming media and other information. In normal business applications, each display screen will independently display its main scheduling and monitoring information; when it comes to emergency handling, each group of splicing display screens needs to flexibly schedule and display information according to different scenarios.

Scene display

All kinds of different large screens need to display related video information in multiple modes, and can adjust the display status and display mode in different situations such as monitoring mode, emergency mode, and visiting mode in multiple places. Including arbitrary adjustments to signal source size, position, and layer status.

Overall application environment

Command requires real-time signal display and fast switching, and requires large-screen display subsystems with good stability, good reliability, good maintainability, good support, high testability, high safety, strong environmental adaptability, and strong electromagnetic compatibility. The entire system should be able to access monitoring information such as professional systems, depots, police stations, train monitoring, etc., to achieve interconnection among various regions. The monitoring platform of multiple control centers can be integrated in the dispatching command hall to monitor the monitoring screens, traffic dispatching information, main control system information, etc. in various places, so as to realize the centralized allocation of resources.
