Application of HD network monitoring in the field of intelligent building

In the rapidly developing information age, the degree of building intelligence has gradually increased with the development of science and technology. Nowadays, the networked video surveillance system is more powerful for the creation of intelligent buildings. It not only facilitates the docking of the various subsystems of the intelligent building, but also provides remote real-time monitoring of multiple places in the building, greatly reducing the redundancy of personnel in the previous building management. At the same time, the use of high-definition network video surveillance systems for intelligent building monitoring systems is becoming more and more popular. The high-definition network video surveillance system has the characteristics of high picture quality, accuracy, real-time and rich information content. As a comprehensive system with strong prevention capabilities, it provides both the management of the safety of the building environment and the integration of various systems in the intelligent building. Technical Support.

How the intelligent building HD network system is set up in the actual project, and what functions does it have? The following is a detailed analysis of the Jin Sanli HD network overall solution adopted by IWC Shanghai Data Center as an example:

1. Project requirements and system composition

The GDC Shanghai data center is different from the ordinary building group, which requires efficient management of infrastructure, reducing operating costs and improving the availability of data centers. Therefore, the project has designed two sets of monitoring systems, one set is for security monitoring. It mainly implements 24-hour comprehensive non-blind spot monitoring on the corridors, stairs, elevator halls, elevator cars and perimeters of the building complex; one set is equipment Monitoring, mainly for 24 hours of all-round monitoring of key infrastructure such as power distribution, UPS, battery packs, generators, precision air conditioning, temperature and humidity, water leakage, and new fan sets. The front ends of the two systems use high-definition 720P / 1.3 million pixel high-definition network cameras, and the back-end uses an advanced and flexible E-NVS embedded network monitoring and management platform to manage storage and forwarding, and then displays and browses on the TV wall through the HD video decoding server. To facilitate later management, the system software sets the system to a large-scale network video surveillance system composed of general control and sub-control. The two systems can operate independently and be managed together. The following is the overall system architecture diagram:

In the system design of the monitoring center, it has set up a set of 69 high-definition video walls composed of 46-inch ultra-narrow splicing screens and 19 high-definition decoding servers, which realizes the functions of browsing, round robining, combining and other arbitrary pictures. Among them, the Jin Sanli ST-CM4670-I4 LCD splicing screen adopts the original dynamic super-resolution technology, which can make the low-pixel images clearly reproduced in the full HD display, and the high-definition images are more high-definition; 6.7mm; with single-screen multi-channel signal, full-screen one-channel signal and any combination display mode. With the cooperation of the Jinsanli HD decoding server, it can output VGA signals and achieve up to 9 images of high-definition image decoding and split output (when a single VGA output), it can also achieve two VGA output and 5 images per VGA port High-definition image decoding and output. At the same time, with the cooperation of the front-end collection and perception layer, the entire monitoring center can truly achieve high-definition monitoring images. The front-end acquisition and perception layer is composed of 720P, 1080P network high-definition high-speed spherical cameras, high-definition infrared network cameras, and high-definition network gun-shaped cameras. They are all encoded using the standard H.264 compression method and support dual stream. Users can choose different video streams for transmission, storage and browsing according to their needs. In addition, Jin Sanli Network HD Camera can provide SDK development kit for secondary development to achieve more functions. And all the network high-definition cameras in the front end can adapt to various network environments to transmit high-quality images, such as LAN, WIFI, 3G, etc. In the alarm function, the front-end network HD camera can support a variety of alarm linkage, including sound and light alarm, information prompt, automatic video capture, Email sending function, etc.

Second, the system platform function

Jinsanli embedded center service platform includes three functional modules: access service module, forwarding service module and recording service module. Among them, the access service is responsible for the registration access and signaling control of users and devices in the entire domain system; the forwarding service is responsible for handling the load distribution of streaming media; the recording service is responsible for the central network storage and on-demand service of the front-end video. With its unique design, Jinsanli video surveillance system has the following functional characteristics.

Dual stream function

The dual stream is to solve the problem that the bit rate can only be set according to the minimum requirements when storing and accessing network video by different users. Jin Sanli's digital products support dual stream of front-end equipment and dual stream of central platform. Can adapt to different network environments for video browsing and storage requirements. Users can choose high-definition picture quality or low bit rate during real-time browsing or storage according to their own needs. Both methods can be used at the same time. Which one to choose depends on network bandwidth and storage capacity. System management.

Disk management

Jinsanli Embedded Platform Server can use RAID for hard disk management (16 bays). A single machine can support up to 16 SATA hard disks and has a hot spare function. At the same time, two hard disks are damaged and data will not be lost.
