Inland China’s Henan Province has been badly hit by torrential rains and floods since mid-July, killing at least 302 people and affecting a total of 14.53 million people (data updated Aug. 2). The heavy rains in Zhengzhou, the capital of Henan Province, exceeded the record hourly rainfall.

Significant assistance from sectors, agencies and individuals across society has been delivered punctually and with determination, and a coherent effort has been made in the work of flood control, victim rescue and disaster recovery in various forces.

Among these forces, which play an indispensable role and serve as a strong shoulder, consists of a number of modern technological products. Enabled by science and technology, it is shown that the precision of weather monitoring, the timeliness of emergency aid and the safety of human lives at stake are guaranteed more than ever.

State-of-the-art technology, warriors on the front lines

Operating satellites in orbit provide observation data for meteorological services.

With the continual downpour and large-scale flooding, it is a Herculean task to determine the extent and extent of the flooding in a limited amount of time through man-made inspections.

Shortly after the flood, the Fengyun series satellites developed by the China Aerospace Science and Technology Corporation (CASC) were used to collect space-based observation data for real-time situation analysis and subsequent disaster assessment.

The FY-4B satellite, which was launched two months ago and is currently in the test phase, was activated in high-frequency fast imaging mode in order to constantly monitor precipitation patterns and trends.

In addition, the Gaofen series satellites including GF-3 and GF-6 have also provided the necessary services to the Department of Emergency Management and the local rescue teams in checking the local conditions and adjusting the relief work.

In addition to transporting supplies and disinfesting epidemics, unmanned aerial vehicles (UAVs) could also be used for lighting and communication. Damaged by the floods, water and electricity connections were cut off in many residential areas and the water supply system in Zhengzhou City urgently needed to be repaired.

As a breakthrough for 300-meter aerial work, the Tianshu A8 docking drone was used immediately to take over a 24-hour service for video monitoring and electric lighting to support the pool cleaning process on the night of July 22nd.

Meanwhile, the Wing Loong 2H unmanned aircraft, a new “face” that was officially unveiled in May of this year and is a high-ranking “expert” in emergency communications, productively coordinated the restoration of the 50 square meter cellular network.

Improved human-technology interactions

Smart devices and human strengths work together for maximum effectiveness.

The surface rescue robot Dolphin-1, an intelligent lifeboat that can carry two or three adults and reach three meters per second with no load, was transported to the flood-hit areas and operated with a remote control over water, so that the rescuers can quickly and stretch exactly on the victims.

At the end of July 22nd, another type of intelligent equipment – a floating emergency bridge – of various shapes was installed overnight to move 1,400 people trapped in Xinxiang City.

It is reportedly one of the most groundbreaking water rescue devices developed by China State Shipbuilding Corporation Limited (CSSC) that can be used to cope with the ever-changing conditions and ensure the relocation of the affected people, hence called “the.” known lifesaving bridge. “

An online document shared by millions of internet users shows social solidarity in cyberspace.

A university student originally from Henan Province took the very first step to create an online spreadsheet and gather information for rescuers and victims.

Minutes later, a few “strangers” added their requests, detailed the locations, or volunteered to classify and verify the information. Hours later, it had forged a transmission chain and attracted tens of internet users from across the country to take part in the race against the clock.

By the 24th hour after its creation, this document had been updated to the 270th version with more than 2.5 million views and countless reposts.

From a small collection of rescue claims to a giant platform connecting multipurpose and multipurpose resources, their only goal – saving lives and fighting the flood – has shown the world that technology is for social good.

Advancement of technologies that witness the development of China

The flow of history will never be forgotten when the flood disaster occurred in 1998, when thousands of soldiers carried countless sandbags on their backs and fended off the rubble with their bodies.

A heart-wrenching flood disaster once again put China to the test today. Only this time, the mass mass strategy was replaced by the consolidation of people and technology, which better helped Henan Province to overcome difficulties.

The technology not only supports poverty alleviation, green development and civil infrastructure, but also supports social and economic advancement, not to mention its immense contribution to fighting the COVID-19 pandemic as China successfully isolates the world’s first virus strain and does viral genome sequencing completed, formulated and administered a billion doses of vaccine and exported nearly half of its production to serve over 100 countries.

It has demonstrated a great sense of security and stability across the country, and has confirmed the impregnable cohesion of the Chinese nation in its tireless efforts to meet all the challenges ahead. And this torch of cohesion has been carried on from generation to generation for over five millennia.

Over the past seven decades, China has attached great importance and determination to scientific and technological innovation from a strategic and long-term perspective.

It is encouraging to note that China has achieved notable achievements such as manned spaceflight, deep-sea submersible, high-speed rail, super hybrid rice, artemisinin, 5G, and countless world-famous achievements.

Announced in March this year, the 14th Five-Year Plan highlights a comprehensive roadmap for technological advances to reach new heights.

The inexhaustible momentum China has put into technological innovation anchors its irreplaceable strengths in leading global technical cooperation, which will further help the world economy and multilateral governance sail into a more promising, prosperous and common future for all of humanity.
