The
Provincial Transportation Center organized the Liaoning provincial
highway engineering emergency exercise in Xinmin City to follow
principles of safety first, precaution crucial, and comprehensive
management. Shenyang – Zhang Liao River bridge and lead line project is
also carried out in this city. Liu Yanxin, deputy director of the
center, is the general director of the exercise. And emergency, fire,
and medical departments were participated in and observed this exercise.
This
exercise was sponsored by the provincial development center and
undertaken by China Railway Nineteenth Bureau Group Co. The length of
this event was about 80 minutes, covering a wide area with more than 100
participants and a complex site environment. The exercise focused on
falling objects, injury, and landslide buried accidents and was
conducted in several places such as the main venue, the first and second
scenes.
At 85 meters from the stage is the main
venue. The cameraman needed to move to have multi-angle shootings for
the speech spoken by the commander-in-chief and the reporter. The
wounded rescue exercise what injuries from falling objects were the
first scene set up sixty meters away from the stage. And the organizer
requires the entire rescue process details to be recorded, so the
cameraman needs to move freely to shoot. Five hundred meters away from
the stage, for the second scene of the collapse buried exercise, due to
various dilapidated buildings, large machinery, and equipment to block,
the non-line-of-sight transmission performance and long-distance
transmission requirements of the wireless video transmission system are
relatively high.
To
meet the needs of this emergency exercise, the organizer decided to use
the Thunder X2 and the Swift800 Pro from CVW after comparing the
performance of other brands’ products.
For the deployment of the scheme, there
are three-camera shooting positions in the main venue. Two fixed
shooting positions are separately placed on the left and right sides of
the main venue to shoot panoramic views. A camera with a Thunder X2
transmitter was used to move freely and shoot the commander-in-chief and
the speaker’s speech.

The first scene has two camera positions: a fixed fiber-optic position to shoot the panorama of falling objects and a camera with a CVW Swift800 Pro transmitter as a mobile position (for the mobile shooting of the whole rescue process).
Swift800 PRO was placed in the first scene
The
second scene was covered by various dilapidated buildings and sizeable
mechanical equipment. The organizer used the Thunder X2 with two DJI
drones to shoot. Because the Thunder X2 has strong wall-through and
anti-interference capabilities that can still achieve stable
transmission in complex non-visual distance scenes. This solution could
effectively solve the problems of long-distance transmission, as the
wireless signal had to pass through many obstacles such as dilapidated
buildings and large machinery and equipment.

Swift800
Pro and Thunder X2 receivers were connected to the switch console with
SDI cables, and the backstage staff edited the received video and
live-streamed it online. Throughout the 80 minutes of the Liaoning
Provincial Highway Engineering Emergency Comprehensive Emergency
Response Exercise, the video transmission signal of the Swift800 Pro and
Thunder X2 always maintained a stable and smooth effect, guaranteeing
the smooth conduct of this emergency response exercise.
When
the exercise was ended, the organizer thought highly of the performance
from Thunder X2 and Swift800 Pro. In particular, the Thunder X2, the
king of wall-through performance, can still achieve stable transmission
in an environment with many obstacles, such as dilapidated buildings and
sizeable mechanical equipment. The Thunder X2 also featured
long-distance transmission, excellent anti-interference immunity, and
other performance, widely used in a variety of complex environments.
This exercise improved the emergency plan system and linkage coordination mechanism in engineering emergencies. It improved the emergency response capability of the emergency rescue team in the face of the province’s highway engineering emergencies.
