One, the background information

With the enrichment of highway construction, more and more people choose long-distance bus travel. But on a long-distance bus, such as theft, robbery incidents also emerge in endlessly. In order to strengthen the safety management, on the long distance bus passenger's life and property security, the need to establish a set of perfect remote video monitoring system.

Some car drivers on the other hand, in order to get an extra ticket revenue, often after a bus stop halfway on violations \"pick up\", cause disorder in the administration of long-distance bus station, a large number of capital outflow, but also safe hidden trouble caused by the overload, serious damage to the passengers' rights and interests. In order to prevent this from happening, the long-distance bus station is on car transport to strengthen supervision. But because car mobility, leading to can't timely grasp the transportation condition.

In also make full use of the wireless network is not affected by time and space of the properties, the influence of long-distance transportation supervision system is established.

Wireless video monitoring solution by 3 g data network transmission video monitoring information, without laying cable network, can quickly and easily in all kinds of need of place to deploy digital camera equipment, set up new video monitoring system or extensions to the existing video surveillance system, has the very strong flexibility and expandability. Video data transmitted through 3 g wireless network, can provide high quality video monitoring, and monitoring is more extensive.

Second, the demand analysis

According to each point of the specific conditions of the () on every car, at the point () on each car to install the corresponding cameras (optional with yuntai camera), used in the real-time video signal point to point. Yuntai can be controlled by the control center of computer user level on the camera for 360 degrees, 90 degrees vertically and zoom control.

Monitoring management center should be able to receive the monitory point (per vehicle) by 3 g network transmission of video information, has the video server in dispatching center, which is responsible for management of each car video collection terminals, and video services for LAN monitoring terminal.

Monitoring management center is responsible for receiving the monitory point through the 3 g network transmission of video information, control center can monitor

Display the field image information of point to point, and digital video, user login management, coordination control signal, video

Data can be deposited in the storage server at the same time, video storage, retrieval, playback, backup, restore, etc. Monitoring personnel can access the server from your computer query playback video footage.

Scene back to the video image is converted into digital signal is stored on the hard disk video recorder, can be convenient to realize data storage,

Update, query, backup, provide the basis for traffic violation processing law enforcement work.

Three, the system function

1. The system has good scalability, with the increase of monitory point, as long as you increase the front-end equipment.

2. The user can through the monitoring center TV wall or computer client round jump cuts, real-time monitoring for 24 hours on end.

3. The system has the monitoring, video recording, playback, transport and function of backup, SD card storage device support the front

4. Smart phones can be used, the client and the TV wall in a variety of ways to browse the front video image point to point.

5. Support the front-end yuntai control.

6. Support two-way voice intercom.

7. Perfect system log management functions

Characteristics of the equipment

1. TVS1300 3 g wireless video server support 9 v - 25 v wide dynamic power supply

2. Adopt the efficient H264 / AVC encoding, high compression rate and image quality is good, single card can support D1

3. The optimized design of channel dynamic adjustment technology, network transmission error correction technology, under the limited bandwidth to ensure the fluency of the video data transmission

4. Support multiple link binding technology, support 3 g wireless module 2-4 road, can significantly enhance the transmission bandwidth of wireless network, in multiple bundling, used the multi-channel automatic balance coordination of transmission technology, to maximize the use of transmission bandwidth

5. Wireless transmission delay is small, the average delay is less than 3 seconds

6. Support the double stream coding, wireless transmission and local video using two independent code flow, maximum saving wireless network bandwidth
