The matrix transform dialysis surveillance devices modular design direction (1)

Recently, the world of great digital surveillance equipment universal modular structure design for patents issued by the State intellectual property office.

The patent in order to achieve the functionality inside the matrix modules and flexible combination, providing advanced solutions to expand the matrix application areas, a more unified structure of regulated products, it is the first in the industry.

The domestic market status

Security system depending on customer needs and technology implementations, broken down into a number of functional modules, including: audio and video switching, front-end cloud lens control and alarm acquisition linkage, digital video storage, network transmission, access control management and forwarding of data transfer, etc.

Each functional module after years of development, has become a separate industries and product lines. In the video surveillance for the control of the core of a typical security project, involves the application of specific products like: video matrix, the audio matrix, DVR, network video server, alarm signal processor, the access controller, etc. Each device for different functions, up to a different role to meet the needs of users relatively independent, so the design into different functional boards and hardware structure, chassis size specifications and appearance of the craft also varies. This situation continued for decades, but in IT technology changing and an all-encompassing an increasingly competitive environment, security enterprise doing product strategy planning, could face two problems: first, the focus on industry solution, how to integrate a number of different categories of products, to provide users with high integration level/use convenient/operation/maintenance of efficient integration product/system; second, in response to price competition, must implement cost compression and quality control of industrial requirements. The original market demand slow times, Security Enterprise head is offering more low production of each product corresponds to an even multiple hardware structure, resulting in a variety of equipment card chassis and are not common, there is no guarantee that a unified procurement volume production and quality inspection. The modular structure of the design as the most effective means is profoundly affects monitoring products manufacture and market trends.

Matrix as compared to the typical design of a modular structure, fully embodies the concept of initial ideas.

Its initial appeal more than two points: one is the result of the monitoring system for video sites will increase as the system expansion, while for the protection of user investment considerations must requirements matrix input/output according to actual requirements of any combination of extension; the second is due to the monitoring system for 7 x 24 hours of continuous work, in order to reduce the appearance of various kinds of failures on system downtime and achieve rapid on-site maintenance, you must request the matrix function cards modular. Thus, the matrix of hardware components typically include: rackmount chassis, bus back Board, CPU control unit, power supply module, video input module, video output module and character overlay module, switch module, loss detection module, data buffering module card, simply because each manufacturer's design principle, is the distinction and character. But the bus system alarm host while the system structure is different, but in terms of implementation, is divided into alarm host, bus driver modules, 8 zone expansion modules, single/dual zone input module and alarm output module, etc.

Technology development and reform of

But careful analysis shows that even the matrix such earlier realization modular structure design of the product, there is also a larger limitations, such as each feature card can only be placed on the back panel fixed slot combinations cannot be flexible and have a video input and output modules support extensions for system extensions add new functionality.

As the video surveillance system point capacity and coverage of fast lifting, video surveillance and alarm review of linkage of surging, and audio and video information network-shared with the increasing popularity and customer facing system expansion card installation of complex difficulties, deployment and maintenance costs, the demand for new features to meet the upgrade.

To address this challenge, the world undertaking in 2007 in the industry's first proposed universal module structure design idea, creatively developed MSIP platform technology, this advanced technology has been ported to intelligent network matrices, multiservice optical transceiver, network video server and multiple industries and product lines.

Its core idea is the audio/video input/output, OSD, full cross switch management, optical receiver transmitter, alarm input/output, network video codec, access control management and other functional modules in accordance with the standard protocol unified hardware interface and the underlying protocol stack, the standard rack-mountable chassis embedded rail hopper Assembly to universal bus back panel. The various functional modules according to uniform standards to encode property category in accordance with the actual demand for flexible matching, built into the universal bus any slot backplane, card number location does not have to address to limit, the system automatically scans run fast on the line after recognition, future customers can extend upgrade maintenance of various functional modules, system deployment cost reduction of at least 20%. Installation easier and faster, more stable production quality.
