According to domestic media reports, at the Luoyang-Gree China Intelligent Manufacturing Summit Forum on August 1, Gree Electric’s Dong Mingzhu said that companies should have higher-end R&D centers in China, and Gree’s 15,000 R&D personnel do not have a foreigner or A returnee.

　　 Dong Mingzhu said that the money we make as a business is not placed in our pockets, but rather willing to take it out, cultivate our own team, and cultivate outstanding R&D personnel.

"I remember every time I went to a company at that time, everyone said that I had introduced the most advanced equipment in the world. I also said where my talents come from, and some people said which country the R&D center is located in. Just advanced."

　　 Dong Mingzhu said frankly that he is different from what others think. I think we should have a higher-end R&D center, which is in China. Therefore, all of Gree Electric's 15 research institutes are in Zhuhai, and none of them are abroad. None of our 15,000 R&D personnel is a foreigner, nor is there a returnee.

　　 It is worth mentioning that Dong Mingzhu, chairman and president of Gree Electric, said in an interview that no company now dares to advertise "one kilowatt per night". This statement is actually a secret change.

　　 Dong Mingzhu said that now some of the more than 1,000 cheap air conditioners are sold to renters, because they do not live for rent, so they are the cheapest to buy. But when the tenants live in, they are unlucky, not only the electricity bill is very expensive, but also the noise is very loud.

　　 Regarding the previous corporate propaganda of "one kilowatt-hour of electricity", they actually changed the concept. The actual situation is that the ambient temperature is constantly changing, and the air conditioner needs to be adjusted according to temperature changes. And often shutting down and restarting is the most power-consuming, this process may require one or two kilowatt-hours of electricity. Gree's air conditioner cannot be said to be "one kilowatt per night", but it should be no problem to save half of the electricity.

The completion and opening ceremony of the Beidou-3 global satellite navigation system was held in Beijing on the morning of July 31.
It was learned on July 29 that the 55th Beidou satellite navigation system (Beidou-3 geostationary orbit satellite) has completed in-orbit testing and network access evaluation, and has officially entered the network recently, using the ranging code number 61 to provide positioning and navigation timing. service. The satellite was developed by the China Academy of Space Technology and launched at the Xichang Satellite Launch Center on June 23, 2020.

Big Dipper has five abilities

The short message communication function is a "unique skill"

The Beidou satellite navigation system is an important space infrastructure independently constructed and operated by my country. It is also the largest complex space system with the largest scale, the widest coverage and the highest service performance requirements in my country so far.

Speaking of Beidou, the first reaction of many people is "navigation and positioning." Real-time navigation and fast positioning are the most basic functions of a satellite navigation system. In addition, Beidou also has three characteristic functions: precise timing, position reporting and short message communication.

"The Beidou satellite itself is a time service system in our country." Lu Xiaochun, deputy director of the National Time Service Center of the Chinese Academy of Sciences, said that the accuracy of the satellite-borne rubidium atomic clock on the Beidou-3 satellite is at the international leading level, reaching 5/10 billionths of a second per day. At present, this function has been widely used in communication, power, financial and other systems.

The position report function is closely related to the characteristics of Beidou's "active positioning". Active positioning is a major innovation of China's Beidou. It uses radio measurement technology and two geosynchronous orbit satellites to work together. It can not only answer the user "Where am I", but also tell related parties who follow the user's whereabouts "Where are you". Widely used in search and rescue, fishery and other fields, it is a "clairvoyance" to ensure people's livelihood safety.

The short message communication function is the "unique skill" of the Beidou system. Navigation satellites and communication satellites are two types of satellites, but Beidou navigation satellites have additional communication functions. Wang Bo, deputy secretary-general of the China Satellite Navigation and Positioning Association, said that Beidou users can not only know their location through the terminal, but also tell others about their situation through short messages. This function is essential in areas where there is no network coverage such as deserts, oceans, deep mountains, and forests, or when disasters occur and communications are blocked.

In the Beidou No. 3 system, the ability of short message communication has been significantly improved. The ability to send information has increased from 120 Chinese characters at a time to 1,200 Chinese characters. It is widely used in many fields such as ocean fishing, rescue and disaster relief, and global search and rescue.

Benefit domestic services to the world

It is understood that the "Beidou" industrial chain is mainly concentrated in the user segment of the Beidou system, which is divided into three major links: upstream basic components, midstream terminals, and downstream operation services. Among them, the upstream basic components are mainly chips, boards, antennas and other basic components; midstream terminals mainly refer to navigation and positioning devices that can receive "Beidou" signals; downstream operation services mainly refer to government and enterprise users, industry users, Service providers and mass consumers provide various basic services such as positioning, navigation, timing, and short message communication based on "Beidou".

From providing services for the Asia-Pacific region to providing services for the world, Beidou's global networking not only means that Beidou has a wider service coverage, but also benefits the entire industry chain. Related industry chain products have an additional support system. These products The user experience, stability, and reliability of the device will be greatly improved, especially in the chip and terminal industries.

The efforts of Beidou's entire industrial chain benefit both domestically and globally. "In 2019, Beidou's overseas application cooperation and trade exchanges will become more frequent. Domestic Beidou basic products have been exported to more than 120 countries and regions. Based on Beidou's land right confirmation, precision agriculture, smart construction, smart ports, etc., it has been in ASEAN, South Asia, and Eastern Europe. , West Asia, Africa and other places have been successfully applied." Yu Xiancheng said.

Applications are only limited by imagination

The signal is on the horizon and applied around.

From clothing, food, housing, transportation to water, electricity, gas, and heat, from agriculture, forestry and fishery to disaster relief and mitigation... Beidou satellite navigation system is deeply integrated into social life and penetrates into all aspects of economic and social development.

Which way is smoother when driving on the road? How long does it take for the bus to arrive at the station for public transportation? How can I find a bike quickly when sharing a ride? No matter what mode of transportation you choose, you cannot do without the Beidou satellite navigation system.

The transportation industry is one of the largest users of Beidou satellite navigation systems. Beidou system is widely used in key transportation process monitoring, highway infrastructure safety monitoring, port high-precision real-time dispatch monitoring and other fields.

According to the "White Paper" data, as of the end of 2019, there were more than 6.5 million operating vehicles, 40,000 express and postal vehicles, about 80,000 buses in 36 cities, more than 3,200 inland navigation facilities, and more than 2,900 maritime navigation facilities in China. The Beidou system has been applied to the facilities, and the world's largest dynamic monitoring system for operating vehicles has been built.

When agriculture meets Beidou, planting is more labor-saving, seedling emergence is more worry-free, and labor productivity is greatly improved. In the farmland of Dashetai Town, Uradqian Banner, Bayannaoer City, Inner Mongolia Autonomous Region, unmanned planters are changing from "rare" to "common". Based on the Beidou positioning function, the planter operates on its own along a preset route. With this precise and scientific method, the seeding deviation per kilometer does not exceed 2 cm, and the seedling emergence rate per acre can increase by 10%.

When disaster warning meets Beidou, people are safer and property is guaranteed. Not long ago, in Leijiashan, Shimen County, Hunan Province, thanks to the "Beidou Satellite High-precision Earth Disaster Monitoring and Early Warning System", a timely warning was issued. Villagers located in the landslide-risk area were moved in time without any casualties. Through 24-hour real-time monitoring of the deformation and displacement of mountains, reservoirs, and rivers, Beidou provides early warning of possible landslides, subsidence, cracks, reservoir distress, and river water level surges to protect lives and reduce losses.

On the special battlefield, Beidou also responded quickly and played as sharply as possible. At the beginning of 2020, a battle against the new crown pneumonia epidemic was fought in the land of China. Vulcan Mountain and Leishen Mountain Hospitals rose on the ground. It was Beidou that achieved high-precision positioning and accurate mapping of complex terrain and landforms. The "location-finding" online drone platform can realize the precision spraying of drones and other epidemic prevention operations. It is also Beidou that provides high-precision data for it; material transportation vehicles are monitored and controlled in real time, and intelligent robots quickly send medical supplies from various places. The support system behind the hospital quarantine area is Beidou...

The Beidou system collides with new technologies such as 5G mobile communications, blockchain, Internet of Things, and artificial intelligence to build an emerging industrial ecological chain with Beidou space-time information as the main content, and promote changes in production and lifestyles and continuous innovation of business models. Create huge economic and social benefits.

In the future, Beidou has unlimited possibilities. Just as Academician Sun Jiadong, the first chief designer of the Beidou satellite navigation system, once said, “The application of Beidou is only limited by human imagination.”

　　Huawei British spokesman Edward Brewster said:

　　 This decision is disappointing and is bad news for all mobile phone users in the UK. This may cause the UK to fall into the slow lane of digital development, increase consumer spending on communications, and deepen the digital divide. This move will not only "enhance" it, but it will reduce Britain's development level. We urge the government to reconsider this decision. We are confident that the new US regulatory measures will not affect the resilience and safety of the products we provide to the UK.

　　 Unfortunately, Huawei’s future development in the UK is politicized. This move stems from US trade policy, not security issues. Over the past 20 years, Huawei has focused on building better network connections in the UK. As a responsible enterprise, we will continue to support our customers as always.

　　 We will carefully examine the impact of today's (14th) statement on our future UK business and communicate with the UK government to clarify how we will continue to help the UK build better network connections.
