More than 10 km wireless monitoring system along the railway line

Posted on

1.1 Construction Description
For the safety and management of a railway section, a high-definition monitoring system was constructed to meet scientific and efficient management.
1.2 Project Description
Due to the requirements of the project, six monitoring points for video transmission are being implemented. Therefore, the following plans have been designed for this project:
Solution: 6 monitoring points, 1 and 3 respectively have 4 2 million network high-definition cameras, 2, 4, 5, and 6 respectively have 2 million high-definition network cameras, and 6 monitoring points on the video The monitoring signal is transmitted to the monitoring center via a wireless bridge.
The distance from 1 to 7 is 10.9 km, the distance from 2 to 7 is 9.3 km, the distance from 3 to 7 is 7.6 km, the distance from 4 to 7 is 5.8 km, the distance from 5 to 7 is 3 km, and the distance from 6 to 7 is 1.5 km .
According to the distance from the monitoring point to the 7 monitoring center, the scheme is as follows:
The transmitting end:
1,2,3 points respectively mounted an integrated antenna LA-5825 outdoor wireless bridge as the transmitting end (point of each camera are aggregated to the point of the switch, then the switch and bridge connections, Send video signals to 7 monitoring centers.)
4,5,6 points respectively mounted an integrated antenna LA-5839 outdoor wireless bridge as the transmitting end (point of each camera are aggregated to the point of the switch, then the switch and bridge connections, Send video signals to 7 monitoring centers.)
Receiving end:
1 monitoring point with a LA-5825 receiver in the 7 monitoring center one-on-one reception;
The 2 and 3 monitoring points use a LA-5825 as the receiver to transmit data in a two-shot mode.
The monitoring points 4, 5, and 6 are received by a single LA-5839, and transmitted in a three-in-one manner.
The last 7 monitoring center 3 receivers are imported together into the equipment room switch to connect the monitoring host and display on the wall.
Note: The wireless bridge and camera are connected via a network cable.
The network connection extension is shown in the figure below:
