Site briefing: This is a wireless monitoring system of mining, the environment is more complex system.

3,4,5 3 Video camera In the mining pit bottom, and the monitoring center can not achieve line of sight.

1,2 camera number and the monitoring center can achieve line of sight.

6,7,8,9 camera through the cable connected to the manner and monitoring center.

3,4,5 and 2 ball machine to achieve line of sight.

1 camera most 3 km away from the monitoring center.

System requirements: -Camera 1-9 can all transfer to the monitoring center, and to control Head Rotation.

D1 image quality requirements Can save half of the image.

Solution: 6,7,8,9 four point four of D1 through a Video Server Connected to the monitoring center, the purpose and the rest of points in a compatible, able to control the software in a 9 camera.

Three cameras as 3,4,5 and the monitoring center can not be visual Bottom, but can and 2 video cameras, we use a bit of the four-point solution to point the camera at the 2nd Department set base station, monitoring center set to a remote site. No.

1,2-camera through the roof of another bridge base station receiver.

Monitoring center roof with a 12dbi omni antenna and a 14dbi antenna, 1 camera with 24dbi directional antenna, 2 points, and 14dbi antenna with 12dbi.

1-5 control points using the server + bridge + video + camera transmission antenna.

Tested, 11M wireless bridge, 3 km away on the 1st control point of the effective bandwidth of 5.8Mbps.

(Customer project is still in use more than nine months without trouble.)

I. System Overview Mine Video Surveillance , Mine monitoring, wireless monitoring mining, coal wireless video surveillance, remote monitoring system mines, coal mines as one of high-risk industries, Security Production is always top priority. As the coal mining areas complex, underground operations from the ground, terrain, poor environment, so prone to accidents, work on underground mine safety video surveillance is an important part of the production. However, a number of coal used in the current video surveillance systems are basically the early analog (CCTV) or number ( DVR ) Monitoring, performance and stability is not high, difficult to maintain, can not be achieved more control centers and multi-level monitoring and management, not suitable for the current authorities of the coal mine safety production supervision and management requirements. As the network Technology And computer technology, based on TCP / IP protocol of the IP network is widely spread application. The completion of high-speed broadband backbone and regional rapid development of high-speed access systems, and promote a variety of IP-based video communication applications. Therefore, the introduction of coal mine safety monitoring system of modern network video surveillance system has become a trend. Another wireless network video surveillance system for remote monitoring provides new ideas and more room to achieve a point-based streaming media , multipoint, multi-to-multipoint multicast remote real-time coding (radio) and monitoring, remote control camera functions

Wireless network video surveillance system for remote monitoring to provide a new and wider concept of space and streaming media-based point to point, multipoint, multi-to-multipoint multicast remote real-time encoding (radio) and monitoring, remote control camera functions. Wireless video surveillance system has a powerful user management features, good compatibility, easy scalability, distributed management and many other advantages, can fully replace traditional analog CCTV systems and digital DVR systems, and more, more within the industry to create and inspire a new application model.

System Overview 2, system Front-end (monitoring points): Camera (explosion-proof camera), video server (which can be accessed cameras, smoke system, infrared alarm system, methane detection system, audio, etc.). If you need wireless transmission, but also select the Wireless Bridge.

Back end (control center): a computer server. If wireless, wireless bridge need to set up. For TV wall control is required decoder.

3, the system works: Front-end server to use video cameras, infrared alarm, smoke detector, etc. into a digital signal, based on TCP / IP transmission control protocol in the network. This can be achieved as long as there is network connectivity remote monitoring. Coal-based regional network development

incomplete, need set up their own network. Optical fiber or microwave can be used to build the net. As the fiber cost is too high, it is recommended to build the net using wireless bridges.

Back through the computer monitor directly to the various points of the site conditions, by increasing the voice gateway can implement and monitor real-time phone fax contact point! If you need the TV on the wall, given the increase in decoder can!

4, the system summary:

The system is a simple networking program, usually only need to add the video server and wireless bridges can transform the existing analog network. Will not result in waste of the original network.
