1、project background
The project is a
wireless monitoring project for Beijing Shidu Scenic Spot.
Shidu Scenic Area is located in the southwest of Fangshan District,
Beijing. It is the only large-scale karst karst landform in northern China.
Shidu Scenic Area is China's national AAAA scenic spot and China National
Geopark. On September 17, 2006, UNESCO officially approved and awarded the
China Fangshan World Geopark. The successful application of the park has added
a science-based world geopark to Beijing, which has made Beijing the first
capital city in the world to have a “world geological park”.
There are eight parks in Fangshan World Geopark, among which Shidu is the core
park of the eight parks, Shidu Park. In order to better manage the scenic spot
and ensure the safety of tourists, it was decided to install a wireless
monitoring system in the Shidu Scenic Area.
According to the actual environment, it is seamlessly built on the basis
of the original transmission system, and it is economical, convenient and
beautiful. Therefore, it is decided to adopt a wireless video surveillance
system. In this project, Feng Runda mainly acts as a transmission equipment
provider for wireless monitoring systems, providing high-quality,
high-performance wireless bridge equipment to ensure the smooth completion of
wireless monitoring systems.
2、project needs
In order to build
a wireless monitoring system with clear picture, high early warning, strong
controllability, and timely command and dispatch, the following requirements
must be met:
1. Ensure that the network is
connected to monitoring points distributed in various areas to monitor
real-time in and around the surrounding areas of Shidu Scenic Area;
2, effectively avoid the same
frequency or other interference sources to ensure that the transmission picture
is clearly visible;
3, easy to install and install,
shorten the project construction cycle as much as possible, improve safety
warning;
4, effectively resisting the
intrusion of outdoor bad weather, ensuring stable and smooth network
transmission;
5, to facilitate the system's later
expansion and maintenance management;
三,solution design
According to the customer's demand, the
monitoring picture is clear and the transmission is stable. Fengrunda decided
to use the RD-S400CPE outdoor wireless bridge as the transmission backbone
device in the wireless transmission network. The bridge is waterproof,
sun-proof, lightning-proof, and built-in modules, eliminating the need for
cumbersome power wiring.
According to the monitoring scope and the
distribution of monitoring points, 40 pairs of RD-S400CPE bridges are used and
installed in various areas around the Shidu Scenic Area. One-to-one, one
receiving video signals from the surveillance camera. The other sends the video
signal to the monitoring center.
Through the display screen of the
monitoring center, the manager can monitor the situation inside and around the
Shidu scenic spot in real time to ensure the safe and orderly management of the
scenic spot.

4、equipment on-site installation
The construction personnel need to install the
surveillance camera and the transmitting wireless bridge at the front end, then
install the receiving wireless bridge in the monitoring center of the back end,
connect the NVR and the monitor, and complete the hardware installation of the
whole system.
The installation of the whole system
is very simple, saving a lot of manpower, material resources and time cost. The
control of each image in the back-end monitoring room is very simple, which is
beneficial to optimize management.
During the installation, you need to
pay attention to determine the location of the monitoring center. Try not to block
the transmitting end and the receiving end as much as possible. After the
installation is complete, you need to configure a valid IP address and perform
calibration and debugging.

5、Five, solution
features
1. The whole transmission scheme design and the
selected wireless bridge equipment are convenient, beautiful and efficient, and
are compatible with the project environment and project requirements.
2. The wireless transmission system
has low investment cost and high scalability, and can be realized only by
adding front-end equipment, transmitting end and receiving end bridge.
3. Through the construction of the
wireless monitoring system, the urgent task of the safety monitoring of the
Shidu scenic spot was successfully solved, which provided convenience for the
later management.
