Preface

Maintaining efficient rail operation at highest levels of customer satisfaction are important benchmarks for modern railways working in a competitive market. Many rail operational areas are already well covered through with dedicated telecommunication solutions such as eWBB, Passenger Information Systems and railway multi-service bearer networks. Huawei’s Video surveillance solution for Railways is a further area where Huawei helps railways to achieve their operational targets. Digital video surveillance provides direct access to information relevant to supervise and adapt ongoing railway operation. Automatic processing of this information can be used to provide decision criteria for traffic scheduling, advanced passenger and crowd management inside stations and on platforms. Modern video analysis tools access these video streams and can automatically provide supportive information relevant to disaster prevention, access control for passenger and freight services on board and to ground based staff.

Based upon more than 20 years’ of experience in the information and communication field and more than 10 years of experience with Railway communication solutions Huawei today offers a comprehensive range of communication solutions specifically designed for Railways. Huawei railway intelligent security video monitoring allows long-range, large-scale, multi-level linkage architectures thanks to its intelligent, high-definition, high-reliability hardware design.

Railway Security in Mind

Public rail transport is one of the most important transport modes to counter congestion and pollution from the road or aviation sector. Ensuring passenger and cargo transport is running smoothly safety relevant communication systems have already been put in place in most railways. However, these system provide very little information about the situation of passenger and cargo using the train. To ensure security of passengers and cargo other measures are taken such as security staff, fencing and access control to secure locations. Such measures are efficient but costly to maintain. Huawei’s Video Surveillance solution provides a cost efficient solution ensuring security of passengers and cargo.

Typical Railway Video Surveillance solutions require large-scale, long-distance, multi-service scenarios. Most commercial of the shelf Video Surveillance solutions are designed to cope with typical SOHO or home use environment. Taking security seriously geographical redundant control centers with multi user and hierarchical rights management are required to control, monitor and access video storage facilities. For this reason Huawei’s Video Surveillance Solution makes use of our scalable Data Solution based on our Cloud Computing architecture.

Besides the specific rail demands on size and architecture Railway use requires high-definition video streams for scene playback, post incident investigation and data collection. Our intelligent analysis platform allows retrieving of large scale video data for automated video analysis and support implementation of an alarm and early warning systems for Control Centre Staff. Huawei’s Video Surveillance Solution are designed to cope with stringent demands on transmission, processing and storage of high-definition videos.

Digital video processing with its intuitive, easy storage, retrieval and sharing features, has become an important part of the railway video surveillance solution. Authorized staff can access remote monitoring through control centre terminals or mobile devices. The location of the control centre or the creation of a number of geographically redundant control centre are design features that can easily be achieved with Huawei’s versatile Video Surveillance Solution. Our Intelligent modular video processing software performs a large number of data analysis on user defined locations in order to improve overall efficiency of the security staff. Key benefits of Huawei’s Video Surveillance Solution are:

• Multi-department unified access and information sharing user accounts
• Multi-level management situation specific resources allocation
• Multi-service unified management
• Intelligent analysis: identification, counting automated alarms
• Video playback and post incident analysis
• Opening interface architecture to integrate existing surveillance infrastructure
• Emergency incident support: Making decisions quickly and handling emergencies efficiently thanks to information obtained from video sources

Huawei Intelligent Railway Security Video Surveillance Solution

Huawei Intelligent Railway security video surveillance system requires underlying broadband wireline or wireless data networks. The system supports real-time monitoring; video storage; video retrieval, playback, PTZ camera control and many more basic and advanced functionalities. All these functions require a network architecture that is designed taking into account strong demand of video processing to the bearer network as depicted in Figure 1 below.

Front-end

The front end system is mainly composed of the individual cameras and the associated access system.

In the Stations:

Solution Highlights：

• H.264 video encoding and decoding for High stream playback, low-stream storage;
• Intelligent analyzing software in application layer allows processing of HD streams to further improve precision of detection algorithms.

In Sections:

Video surveillance systems are used in Tunnels, Bridges, railway level crossings, platforms and other “hot-spots”. A vast variety of cameras can be deployed depending specific requirements of their location i.e. infrared, adjustable focal points, long distance zoom and maximum scope monitoring. High anti-seismic, anti-shock, dustproof and rain-proof features allow all-weather monitoring 24/7. Software features such as contrast ratio; automatic multicolor to black and white during night as well as other correction algorithms are supported.

On the Train:

Establishing real time Video surveillance on board the train is one of the most challenging scenarios in the railway environment. Thanks to Huawei’s eWBB solution the bridge between train based and ground based Video Surveillance infrastructure can be established using state of the art capabilities of Huawei’s in-house LTE technology. Typical mounting points for Video Surveillance equipment are forward and rear looking cameras within the locomotive as well as cameras inside the passenger carriages or drivers cab. In railway carriages and inside the cab, “fisheye” or wide-angle domes are widely used; hidden high-speed HD Cameras are preferred to monitor entrance areas for people counting and for baggage areas. Anti-seismic、anti-shock characteristics ensures given camera reliability throughout their lifetime.

Solution Highlights：

• eWBB transfers real time video streams from train to ground;
• Wide choice of camera and lens types for various on board scenarios;
• Versatile on-board off board data storage facilities and synchronization mechanisms to minimize impact to train to ground communication.
