Construction background
As an important part of urban public transportation, urban rail transit bears the problems of interconnection among urban centers and a large number of travel demands. With the accelerated development of urbanization and motorization in China, urban rail transit suffers from traffic congestion. Vigorously developing public transportation and forming a comprehensive urban transportation system with rail transit as the core are the most effective means to solve traffic congestion in cities. Meanwhile, the unified dispatching, operation and maintenance management of metro by the command center are facing huge challenges. Original single management mode of operation is no longer adapt to the new situation, different line through the interchange station and contact line, all lines in the wire mesh weaving into a net, interrelated and inseparable, make the operation management can no longer be limited to this line, and then according to the line between unrelated single management way already can't satisfy to the need of network operation stages, must set up a network management institutions, global online network level overall plan as a whole to consider each line operation management, improving the rail transit network operation management level and efficiency, guarantee of the rail transit network operation safety and strengthen the emergency disposal ability, Improve the overall service level of rail transit network.



The construction of the target
Multi-category video information needs to be displayed on the big screen of the command center, and high-resolution visualized images of the integrated command and power dispatching platform of the wire network system platform need to be displayed. ATS original double vision image, CCTV video platform monitoring video signal; The seat collaboration system pushes image signals, ACC and data center visual images and other signals for access.
Through the seat cooperation system, the man-machine separation of the seat terminal computer in the scheduling hall and the integration of the keyboard and mouse can be realized, and the flexible seat and information sharing and pushing can be realized, as well as the support of the dispatcher. Optimize the environment of the dispatching hall, reduce the electromagnetic radiation and noise, and set the terminal hosts in the professional room to reduce the system failure rate. The KVM collaborative management system needs to display and call the ATS, SCADA, ATS parking lot/depot, CCTV, AFC, GIS/GPS information and plan system information. The main functions are as follows:
1. Aggregation and integration of the whole platform, sharing, interaction and collaboration between the system information data servers and workstations
2. The command seat can operate different application systems or information platforms at the same time to realize resource sharing and arbitrary allocation according to its own authority
3. The seats can cooperate with each other, including single screen, multi-screen and cross-department cooperation, and the required resources can be pushed to the seats during operation
4. Large screen comparison and analysis of various information or data synchronously or asynchronously, the display system has no black screen switching, and has the ability of fast screen switching
5. The system has good usability and emergency mechanism, humanized, operable, convenient user interface and emergency plan
6. Ensure the security of data and the stability of the system, without equipment downtime, and can work 7 x24 hours

Husion solution
HUSION ELECTRONICS KVM collaborative management platform for digital visualization breaks the single structure of each system existing in the previous construction, supports multi-user multi-level permission and multi-operating system application, and provides a highly integrated, humanized and intelligent management platform for the core of command and scheduling.
Lake, electronic professional digital visual collaboration management platform, KVM solution across a network, across different systems, applications, cross-sectoral, many kinds of data application, how to make the operator to "fast, at the same time, compare" handle multiple different data application, at the same time to realize the information interaction between the operator (content, intercom, information) and collaboration related affairs. Can synthesize all kinds of image resources, application resources, data resources in accordance with the prescribed collaborative process and seat control authority for unified management, operation, scheduling, shorten the response time, improve the overall response capacity.
Considering the KVM rail transit command center/operators stability of collaborative management platform is the key of the project construction, so the design of the system USES lake, double link terminals, double network transmission system, the hot standby system structure of double server, realize the collaborative management platform KVM double backup protection, any single point terminal, network, server failure will not affect the normal use of the system, the system robustness is extremely high.

System function
?Visual KVM collaborative management platform can realize the hot key mode of seat staff using a set of local keyboard.
?Push the data information that needs to be put into the display terminal to the big screen or other cooperative seats with one key to realize data collaborative processing and collaboration Multi-network integration, cross-network operation, integrated EMCS, CCTV, SIG, FCS, TEL/ALARM and so on for the business system, numerous and varied functions, lack of centralized seat management system for unified monitoring, command scheduling. By collecting the video, audio, key and mouse of different network segment computers, the KVM collaboration system realizes the takeover of the computer and completely sets aside the limitation of network segment
?Operating across systems, convenient for different operators free scheduling from different operating systems (Windows, Android, MAC, Linux, Unix, Kylin) business platform data content.
?Seat across the multi-screen operation, to achieve one person multi-machine efficient data management, analysis, comparison, real-time operation of multiple sets of data business system, to achieve a set of keyboard, mouse seamless across different screens;
?Seat authority management, the operator account as the center to achieve permission distribution, content push access, audio and video interaction, can be through the hierarchical user management mode, the corresponding administrator to set different access and management authority.

Plan advantage
1. Full light and heat preparation
Fiber KVM cooperative management platform has a perfect redundancy backup mechanism. All input nodes, output nodes, transmission links and servers can adopt dual optical thermal backup/dual network thermal backup and power supply thermal backup. It greatly improves the disaster tolerance of the system to ensure that the system can run normally even in the face of various emergency failures
2. Visual scheduling
Full video preview, large screen echo, drag and drop screen, bring good operation experience; The operation is visible, the node status can be inquired, the peripheral equipment "vital signs" can be presented, the system management is convenient, reduce the maintenance cost
Open interfaces
4K uhd resolution signal, no black screen switching, fast screen switching ability, support various signals, including interfaces such as dvi-i, dvi-d, VGA, HDMI, SDI, 3g-sdi, DP and so on. The system should support multiple resolutions, including VGA, XGA, 720P, 1080P, 2K, 4K.
4. Man-machine separation
The operator is separated from the server and unified management of the server ensures data security, saves command space, reduces environmental heat, improves office command environment, and realizes centralized management of local maintenance, remote control and remote operation of the computer room
5. Group management
Business/operation/command hall monitoring operation seat according to the online business structure, different business island, function island grouping management, combined with authority management, orderly organization of online business, not only to achieve effective data sharing, and properly avoid data leakage
