Solid foundation-mobile vehicle monitoring application analysis (1)

From the perspective of operators, video surveillance has grown into China Telecom important value-added service for China Telecom to integrated information provider has laid a solid foundation.

At the same time, in domestic mobile value-added business multi development environment, the monitor itself toward mobile, intelligent direction. Vehicle monitoring products are the in-vehicle mobile monitor business applications. China Telecom's vehicle monitoring products based on the "global eye" platform and EV-DO (cdma20001x) wireless network, through the in-vehicle mobile acquisition video and other information, remote video browsing, remote control and other features that meet the customer's remote video viewing, remote emergency command needs to "global eye" application customers with anytime, anywhere wireless video surveillance services.

Vehicle-mounted Mobile monitor composition

Vehicle monitoring architecture by vehicle terminal, transport network and monitoring centres and three layers of on-line-consolidated supervision system, provides vehicle theft, robbery, driving route monitoring, in-vehicle exterior wireless transmission of video images in real-time, incident command for rapid response, call functions, to solve an existing vehicle dynamics management issues.

Vehicle monitoring using vehicle-mounted video servers installed, add 3 to 4 cameras.

Video server through EDGE/cdma20001x/Wi-Fi network, monitoring center to vehicles within the images for real-time monitoring and transmission, and adopt a dual stream technology, local video with D1 resolution, network transmission using CIF/QVGA/QCIF resolution, realized the local code storage and remote storage.

Vehicle monitoring system of the main components include: in-vehicle terminal (in-car video server), the monitoring center, transmission networks, etc.

1. vehicle Terminal

In-vehicle terminal is vehicle monitoring and management system of the front-end device, usually the secret to install in a variety of vehicles, vehicle terminal equipment mainly consists of in-car video server, LCD touch screen, external camera, call handles, car alarm and other external devices.

Vehicle-mounted video servers capture audio and video signal and compressed into a digital stream, such as wireless network transmission cdma20001x to user monitoring center, remote monitoring, emergency command.

Vehicle-mounted video servers need dual stream simultaneous encoding, including local independent video stream and net chuanma stream.

Users need to extract the video surveillance data can be used in two ways: first, through vehicle terminal USB port, the second is through EV-DO (cdma20001x, Wi-Fi) remote access.

2. Control Center

The monitoring center is the core of the dispatching system, remote Visual command and control management platform for all site traffic monitoring audio video interactive command, monitoring center electronic maps can display the location of vehicles and, through the intuitive wireless network monitor settings for vehicles, for example by configuring the head, you can remote control car front camera.

At the same time to achieve the monitoring center on controllable range of vehicles in real time, centralized, intuitive monitoring and dispatching, and 110, 119 command center linkage to the timely dispatch Police Department intelligence when it arrived at the scene, guarantee the efficiency of emergency treatment.

3. transport networks

And fixed with a wired network monitoring, on-board monitoring can only rely on the wireless network, China Telecom Mobile network is suitable for wide-area wireless networks, audio and video data transmission network.
