[China Instrument Network Instrument R&D] On March 7th, Guangdong Shenzhen's new-generation dual-polarization weather radar was built and put into operation. It is an important milestone for the development of the meteorological industry in Shenzhen. It is of great significance for Shenzhen to take the lead in modernizing the meteorological system and enhances the meteorological warning. The forecast and meteorological service levels also provide strong technical support for Shenzhen's disaster prevention and reduction, emergency protection and government decision-making.
In 2013, the Shenzhen Public Safety White Paper was issued, which clearly required the establishment of a new generation of dual-polarization weather radar in Shenzhen. In order to implement the “Shenzhen Public Safety White Paper†task, under the strong support of Shenzhen Municipal Party Committee and the municipal government and related departments, the Shenzhen Meteorological Bureau started the project site selection, planning, design, demonstration and other work in early 2014, and it has undergone a radar station site selection. , Application for construction land, radar station design, application of radar frequency, electromagnetic environment test, aviation clearance height test, application for radar station, application for detection of environment, etc. After a series of preliminary work, November 16, 2016 Municipal Party Committee and Government, China Major leaders of the Bureau of Meteorology and the Guangdong Meteorological Bureau jointly announced that Shenzhen’s new-generation dual-polarization weather radar project has officially started construction. At present, the project infrastructure part is being organized and implemented by the Shenzhen Construction and Public Works Department. The construction period is two years, and the infrastructure part is undergoing the final closing. The radar equipment is being produced, installed and commissioned by the China Meteorological Administration Beijing Minsight Radar Co., Ltd. Put into formal operation on March 7.
The design concept of the new-generation dual-polarization weather radar project in Shenzhen is a round of moon and three clouds, of which three are open landscape platforms, and the distance looks like three clouds floating in the mountains. The radar tower and necessary architectural elements are shaped like hanging. A round moon in forest tip. In the construction process, we always adhere to the principle of co-construction, sharing, and sharing. With the strong support and cooperation of Bao'an District Government, Bao'an Broadcasting Group, Shenzhen Airport and other units, the radar station's transportation, power supply, water supply, communications and data sharing The smooth development of other aspects of the construction work has effectively guaranteed the progress and quality of the project.
The new-generation dual-polarization weather radar site in Shenzhen is located at the Yingyu Lake, south of Fenghuang Mountain in Bao'an District, Shenzhen. It is about 6 kilometers from the Pearl River Estuary. It is an important observation base for monitoring severe weather such as typhoon, rainstorm, and hail, becoming a Shenzhen city. The "New Horizon" to monitor severe weather.
The new generation of dual-polarization radar in Shenzhen is the first domestic weather radar with a resolution of 125 meters. From the factory test and field test results of the radar equipment organized by the China Atmospheric Research Center for Atmospheric Data, the radar has excellent performance indicators. In domestic domestic dual-polarization radars, the radar will effectively enhance Shenzhen's ability and precision in monitoring severe weather when it is put into use. The resolution of detection will be increased from 1 km to 125 meters in the original single-polarization radar, which will effectively identify the phase and size of rain particles. Not only can we estimate the rainfall more accurately, but we can also distinguish the types of precipitation.
The radar adopts a dual channel technology in China to meet the national network of weather radars in the South China region. After the network is deployed, it extends the weather radar detection range to nearly 2,000 kilometers to the north; it also meets the weather radar network in Shenzhen, Hong Kong, and Macao. It is required to realize the networked radar and imported radar network puzzles in the Mainland to provide basic support for the fine monitoring of typhoons, rainstorms, and strong convection in the Guangdong, Hong Kong and Macau Bay Area.

Online Inspection System
DNDT series industrial online inspection radiography
system usually applies with leading C-arm structure, it always transmits
workpiece into lead room by table roller, and also can connects with workpiece
production line to be flow inspection, with cooperation between X-ray and
industrial TV, users can view real time inspection images directly, which can
easier judge appearance and type of failure, then finish saving and processing
for the picture to improve its definition.
As most important part of radiography system-image
intensifier/flat panel detector, we applies with products which manufactures by
famous France Thales/Pelkinelmer, varian company, it not only has advantages of
high resolution and low noise, but also with characteristic of big dynamic
range which can offer reliable image information for users.
Electrical controlling unit is an intelligent controlling
system which with core of PLC, it matches with servo driver and rotation coder
which can finish relative inspection procedure and collects images by manual/
semi-auto modes after diameter alignment of different workpiece models.
