"I’m Cha Qiongfang, one of the first aid Hubei players in Shanghai. During more than two months of aid to Hubei, I saw that every medical staff was selfless and fearless, never giving up, racing against time with medical kindness and fighting against the virus, and no matter how tired or bitter they were, they didn’t complain or retreat. I saw the patients tortured by the virus, with the care and encouragement of medical care and patients, fighting death with strong perseverance until they took a step and walked towards the sun with a smile. I saw volunteers selfless dedication, do their best, risk being infected, and send thoughtful services to people in need. I have seen continuous support and care from the party, the government and all walks of life. "

On the last day of the 2020 Shanghai Book Fair, the English version of Diary of Doctor Cha’s Aid to Hubei was launched in Shanghai Jiaotong University. Talking about the origin of this book, Dr. Cha Qiongfang said, "What I saw, heard and thought always moved and inspired me. With my immature but true brushstrokes, I recorded what I saw in my eyes and felt in my heart, so that I can always remember this history and reassure everyone who cares about the frontline anti-epidemic … What I want to do is to pass it on and let everyone discover the truth, goodness and beauty behind the story. "

The Diary of Doctor Cha’s Aid to Hubei is edited by Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine, written by Dr. Cha Qiongfang, the first batch of medical aid team members in Shanghai and the respiratory department of Renji Hospital, and published by Shanghai Jiaotong University Press. It is the first officially published anti-epidemic diary experienced by doctors who aid Hubei in China. From New Year’s Eve to March 31st, there were 67 doctor’s diaries, spanning 68 days of aid to Hubei, which is the most complete anti-epidemic diary published at present. The Diary of Doctor Cha’s Aid to Hubei reveals the code of China’s rapid control of the epidemic, and reproduces the bounden duty, kindness and courage of China people in the face of disasters and dangers under the correct leadership of the Communist Party of China (CPC), and builds a powerful Chinese power with this selfless and fearless spirit. The book has been loved by readers since it was officially published on April 20, and has been reprinted again and again in just four months.

Li Fang, president of Shanghai Jiaotong University Press, said that after the Chinese version of the book was first published, many internationally renowned publishing houses came to discuss cooperation. At present, copyright has been exported in nine languages, including the English version. After many evaluations, naturalogic Publishing House, a leading Canadian academic publisher in the fields of science, technology and medicine, was finally selected for the English version, with very rich academic resources and professional team. The English translation was completed by Professor Ye Xingguo, President of Shanghai Foreign Languages Society.

Xu Jiong, deputy director of the Propaganda Department of Shanghai Municipal Committee and director of the Municipal Press and Publication Bureau, said that the Diary of Doctor Cha’s Aid to Hubei recorded the protection of life by the most beautiful retrograde people and vividly demonstrated the value pursuit of life first. The release of the English version will make China’s anti-epidemic story widely spread around the world, and make due contributions to the ultimate control of pneumonia in Covid-19.

"The publishing industry has truly recorded the pioneers who fought against the epidemic and made selfless contributions, and strived to write a series of anti-epidemic poems with one heart and one mind, which condensed the majestic anti-epidemic forces and bred a great anti-epidemic spirit." Wang Weiheng, a second-class researcher in the Library Department of Publicity Department of the Communist Party of China Publishing Bureau, said that the Diary of Doctor Cha’s Aid to Hubei, which was selected as the topic list of key publications to be published in Publicity Department of the Communist Party of China in 2020, is such a good book that demonstrates the power of example and shows the great spirit of fighting the epidemic. I hope that the publication in more languages can provide overseas readers with a window to understand the real experience of Dr. China in fighting the COVID-19 epidemic and provide valuable China experience for the global fight against the epidemic.

Liu Jianguo, executive vice-chairman and secretary-general of China Publishing Association, commented that Diary of Doctor Cha’s Aid to Hubei has a unique perspective and stands out among many anti-epidemic books, which is the result of years’ deep cultivation in thematic publishing by Jiaotong University Press. Gu Feng, deputy secretary of the Party Committee of Shanghai Jiaotong University, said that Shanghai Jiaotong University supported the publishing house to carefully plan and publish a number of publications that vigorously promoted the spirit of anti-epidemic and popularized the scientific knowledge of epidemic prevention and control, and exported them to influential overseas publishing houses. "To build a world-class university, we must not only achieve a leap in teaching and scientific research, but also strive to be first-class in spreading scientific knowledge and competing for the right to speak internationally."

"It has been more than four months since I returned to Shanghai, and my work has already been on the right track. Outpatient service, ward, consultation, teaching … "Cha Qiongfang said," What is needed now is to continue to do a good job in epidemic prevention and control during the process of returning to work and production. The experience of fighting the epidemic in Wuhan has greatly inspired my future life. I will bring generate’s fighting spirit and dedication to my future work to better serve patients. "

"Pass on China’s anti-epidemic experience and anti-epidemic spirit to the world, and let the world see the’ road map’ of China’s war and epidemic, and the strength of the people of China to unite as one, overcome difficulties together, and build a tower." Dr. Cha expressed special gratitude to readers at home and abroad for their support and love for this book. The launching ceremony was hosted by Shanghai Press and Publication Bureau and Shanghai Jiaotong University, and was undertaken by Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine and Shanghai Jiaotong University Press.

On the evening of January 29th, Zotye Automobile Co., Ltd. (Zotye Automobile, 000980.SZ) issued a performance forecast, and it is estimated that the net profit attributable to shareholders of listed companies will be 750-900 million yuan in 2023, compared with 910 million yuan in the same period last year, which narrowed the year-on-year loss. In 2023, the company’s vehicle business is still recovering, and the sales volume is small. At the same time, the company plans to make provision for asset impairment and bad debts totaling about 300 million yuan to 400 million yuan, so the overall performance is still at a loss.

Fan Zhendong and Malone were replaced by Liang Jingkun and Wang Chuqin in the Asian Cup list published by ITTF. This arrangement is considered that Guoping is training these two players to prepare for the Paris Olympic Games. However, there are also many people who think that Fan Zhendong and Ma Longming should not walk Liang Jingkun and Wang Chuqin in this way. However, there are also difficulties. Liu Guoliang was forced to do nothing, and the German media revealed the reasons.

At Chengdu World Table Tennis Championships, Qin Zhijian gave all five players a chance to play, but Liang Jingkun and Lin Gaoyuan only played in the group stage to feel the atmosphere of the competition. After entering the knockout round, Qin Zhijian always insisted on using the lineup of Fan Zhendong, Malone and Wang Chuqin. Even though Wang Chuqin and Fan Zhendong lost to Zhang Benzhihe in the semi-final, Qin Zhijian didn’t adjust the lineup, and finally won the championship with these three people.

After the World Table Tennis Championships, the entry list of the Asian Cup was confirmed, Liang Jingkun and Wang Chuqin got the opportunity to participate, and Fan Zhendong and Malone, the top two players in the world, were replaced. Fan Zhendong and Malone don’t seem to need the opportunity of the Asian Cup to prove themselves, but the quota of Liang Jingkun and Wang Chuqin is really not convincing. In particular, Liang Jingkun was in the whirlpool outside the court recently, and his finalist also caused a lot of controversy.

A few days ago, German media issued a document in evaluating the World Table Tennis Championships, pointing out that China might not be able to cope with the situation of lacking two superstars at the same time. German media specifically pointed out that Fan Zhendong and Malone have been the guarantors of the success of national table tennis for many years. In contrast, the German team won the runner-up of the men’s team under the leadership of Qiu Party in the absence of three main players, Bohr, Ocharov and Francesca, and completed the replacement problem that should have been solved at the Paris Olympic Games.

German media actually pointed out a problem of Guoping, that is, besides Fan Zhendong and Malone, we don’t have a third stable and reassuring point. As you can imagine, if our team of Lin Gaoyuan, Liang Jingkun and Wang Chuqin sent in the final of the World Table Tennis Championships, I’m afraid they may not be able to beat the German team, but more likely they will be eliminated by the Japanese team in the semi-finals. Therefore, Liu Guoliang let Liang Jingkun and Wang Chuqin participate in the Asian Cup, which was also forced by the situation. He had to exercise these two people in this way.

The national table tennis men’s team has no other way to go now. One of Liang Jingkun and Wang Chuqin must be forced out to make them grow into stronger players. Whether Malone can participate in the Paris Olympic Games is very variable. One of the national table tennis players must be able to join hands with Fan Zhendong to challenge the Olympic champion, which is one reason why Liu Guoliang must walk Liang Jingkun and Wang Chuqin to participate, forcing them to make progress.

There is no doubt that smart factories are the core of the future manufacturing industry. But what exactly is a smart factory, what technology makes it work, and what makes it "smart"?

In short, smart factories are manufacturing facilities that rely heavily on digital technology to improve efficiency and productivity. This means integrating 3D printers, collaborative robots, 5G, artificial intelligence, SERP, cloud computing, edge computing and so on into the manufacturing process.

Looking at the Solution Theater of Smart Factory Expo from the 2021 event.Book free tickets for Smart Factory Expo..

With so many cutting-edge technologies, smart factories can run with speed, accuracy and flexibility that traditional factories can’t match. As the world increasingly relies on digital manufacturing processes, smart factories will only become more common–and more important.

Of course, there is no "magic bullet" when it comes to creating smart factories. On the contrary, numerous emerging technologies have gathered together, bringing the manufacturing industry into a new era. Here, we focus on some key technologies that are indispensable to realize this vision.

Understand the technologies used in smart factories.

3D printing

A smart factory is incomplete without a few 3D printers. These multifunctional machines can use digital design as a guide to manufacture parts and products from scratch. As they can produce items on demand, they are very suitable for prototyping, small batch manufacturing and even customized orders.

3D printing or additive manufacturing gives the technology an appropriate name and is creating a brand-new world for design engineers. It is very suitable for quickly creating functional prototypes and highly detailed end-use parts, and it opens the door to complex geometric structures that cannot be realized by any other means. Far from being a one-size-fits-all technology, 3D printing uses a variety of processes, technologies and materials, including stereo lithography, selective laser sintering, multi-jet fusion, multi-jet, fused deposition molding (FDM), vacuum casting and direct metal laser sintering, all of which can be used to quickly build parts within the scope of plastics and metals.

3D printing can help reshape the future of manufacturing and design. In the modern world, customers demand a higher level of product personalization and customization. Therefore, 3D printing can become a differentiation factor for manufacturers to plan their supply chain strategies. If you can quickly print the exact parts you need on demand, then why do you need to store a large number of complete parts and assemblies, which will reduce the demand for spare parts?

Cooperative robot

Cooperative robot or cooperative robot is another key component of intelligent factory. These physical multifunctional machines are designed to work with humans, making them ideal for tasks such as packaging and assembly. And because of its user-friendly interface, cooperative robots can be easily trained to perform new tasks as required.

Unlike traditional robots, collaborative robots can be deployed in a few weeks, so they can save money quickly. For manufacturers, other advantages of collaborative robots are that they are easy to set up and program, and flexible enough to move around the factory.

Collaborative robots have the potential to take over 3D jobs-dirty, dangerous and boring-many of which are still done by humans. By cooperating with collaborative robots, employees can focus their time on more fulfilling roles and reduce the time spent on ordinary roles, thus improving their overall happiness. This includes getting rid of night shift, which, as we all know, will have adverse effects on workers’ health.

5G

5G is the next generation wireless technology, which will completely change the manufacturing industry. This is because smart factories rely heavily on data, and 5G will provide the high-speed, low-latency connection needed to quickly and efficiently transmit large amounts of data.

5G can provide solutions to the biggest challenges of manufacturing industry, from achieving net zero and attracting future talents to maximizing uptime and accelerating product development. Next-generation mobile connectivity provides almost unlimited capabilities, and it is possible to completely change every stage of manufacturing operations. With so many potential applications, manufacturing is one of the industries that is expected to benefit most from the arrival of 5G.

It is about ten times faster than 5G and 4G, and the peak speed can reach more than 1gbps (gigabits per second). Moreover, unlike previous generations, 5G is not just an upgraded communication network. It was built from the ground up to provide a better user experience, support new deployment models and provide new services.

artificial intelligence

Artificial intelligence (AI) is another area where smart factories lead the trend. Artificial intelligence can be used for tasks such as predictive maintenance, quality control and material handling. With the continuous development of artificial intelligence technology, smart factories will only become more efficient and effective.

Artificial intelligence will see the combination of data collected from sensors, machines and people, and then apply it to algorithms aimed at optimizing operations or realizing lights-out manufacturing. Although we are still a long way from realizing this scenario, in many other use cases, manufacturers are rapidly adopting artificial intelligence and spanning the value chain of the whole industry. Use cases revolve around workplace safety, machine/building management, machine vision and network security.

Combining AI/ML with other technologies such as sensors, machines and human input will significantly improve operations and may lead to new forms of industry innovation and productivity.

Smart factory workshops are usually equipped with SERP system, which stands for "self-repair and error prevention". These systems use sensors to detect errors in real time, and then take corrective measures to prevent errors from happening again. This helps to reduce waste, improve quality and keep the production line running smoothly.

Enterprise resource planning (ERP)

In industries such as manufacturing where efficiency is king, ERP can change the rules of the game. ERP behavior is a method to centrally manage all aspects of facility operations and processes, and allows unprecedented visibility, coordination and management in different processes that make up manufacturing business-ultimately improving operational efficiency.

Considering the numerous processes that must happen every day to keep the facility running, ERP and manufacturing are natural partners. ERP can not only help inventory management, supply chain, maintenance and quality assurance, but also make these processes communicate with each other.

cloud computing

Cloud computing is a must for smart factories. This is because cloud-based systems provide the scalability and flexibility that smart factories need to keep agile. In addition, they can help reduce costs by eliminating the need for on-site hardware and software.

By providing computing services such as server, storage, database, network, software, analysis and intelligence on the Internet (or cloud), manufacturers can realize faster innovation, flexible resources and economies of scale. Cloud services usually adopt a pay-per-use model to help companies reduce operating costs, run infrastructure more efficiently, and expand as business needs change.

Besides cost and speed, other advantages of cloud services include the ability to deliver the right amount of IT resources from the right geographical location when needed; No need for complex on-site infrastructure, such as "shelving and stacking", hardware setup, software patching and other time-consuming IT management chores; Of course, improve reliability and security. In addition, many cloud computing services run on the global network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware.

Edge calculation

Edge computing is another important part of the smart factory problem. Edge computing systems are designed to process data locally rather than send it to the cloud, thus bringing enterprise applications closer to data sources such as IoT devices or local edge servers. This helps to shorten response time and reduce latency, which is essential for manufacturing applications. This approach to data from the source can bring powerful business advantages, such as faster insight, faster response time and better bandwidth availability.

Fundamentally, the data is processed and analyzed closer to the creation point. Edge computing can help unlock the potential of large amounts of data created by more powerful connected devices. This enhanced analytical capability in edge devices can drive innovation, improve quality and value, and provide near real-time insight and predictive analysis.

Digital twinning

VR Digital Twinning Demonstrated in AMRC Digital Operating Room

Digital twinning is essentially an auxiliary system of production facilities, which uses integrated simulation model to quickly find solutions when problems occur.

These simulations enable operators to get a glimpse of the core of physical assets, to determine the ideal operation workflow, and to quickly find clear options by using the current data flow to help system operators make decisions; There is no time and cost involved in testing theories in the real world.

These highly complex virtual models act as exact counterparts (or twins) of physical "things". Sensors connected to physical assets collect data that can be mapped to virtual models. Operators who view digital twins can see important information about the performance of physical things in the real world.

Digital twinning is an important tool, which can help engineers and operators understand not only the performance of products, but also their future performance. By analyzing the data from the connected sensors and combining with other information sources, we can make an accurate prediction.

Conclusion:

As you can see, many things need to be done to build a smart factory. But with the help of these cutting-edge technologies, intelligent factories can run with speed, accuracy and flexibility that traditional factories can’t match. As the world increasingly relies on digital manufacturing processes, smart factories will only become more common–and more important.

Good-looking slums thousands of people, interesting souls, one? What jokes, good-looking pocket interesting soul, I have to! But just like I bought a mobile phone, I am very tangled, oh, I like it, but I can only choose one. This time, PAMU Z 1, in addition to supporting active noise reduction, battery life, or the first support for replacement of the girdle, the true wireless Bluetooth headset. Colorful color matching makes this headset have more "personality."

This time I got the default as the blue version, three-stage stitching and very viable color matching, very suitable for young people. Moreover, the entire headphones are treated with fine sand, which is less likely to contam with fingerprints and oil compared to bright surface treatment.

There is a transparent PAMU label on the right side of the headset, and the white light is lit when the headset charging and charging the charging, which is equivalent to the charging reminder function.

PAMU Z1 still supports the wireless charging Bluetooth headset, and then in conjunction with the price of its true wireless noise-saving headset, it is considered a conscience.

At the bottom of the Type-C charge, see the Type-C interface is popular, and the true wireless Bluetooth headset is generally started, I am very happy as a digital enthusiast. Almost all devices around me are Ype-C interface, and take a Type=C to charge.

To look at the headphones body, PAMU Z1 is an in-ear noise-saving headset, and the three-stage color matching of the charging box. The position of Pamu logo relies on the touch area, and a variety of touch shortcuts can be selected, in the PAMU APP. You can modify the shortcut operation. As for this flat appearance, it is still like a long-term look like AirPods, and there is no problem with the radish vegetables. It is not a problem, and a wide range of sports is also There is no problem.

There are 3 earplugs in the package accessories, TYPE-C chargeline and storage bags are different. This storage bag is the material of leather, not like other equivalents, overall texture will be much better.

The appearance, which was mainly attracted to me. The mainly detachable waist seal design, as well as this day blue is really beautiful, very good. Other ways to get the textured texture is also very comfortable, others are very square, there is nothing special.

The PAMU Z1 employs a 10 mM titanium composite diaphragm unit, and the unit resistance is 32Ω, coupled with six EQ sound captured in the app, and the overall performance is normal. Supports SBC and AAC regular audio encoding.

In order to better test the sound quality performance of PAMU Z1, I chose the two songs of Tsai Qin and "Hotel California", and close all EQ sound effects in the app, with the default mode for testing. Selecting these two songs because Cai Qin’s "ferry" is very suitable for testing high and low frequency and vocal performance. Cai Qin’s voice is really beautiful, "Hotel California" is very much specifically, you can test dynamic range, musical instrument positioning and Sound field performance. Also selected 192.0 kHz original source, you can see that the file size is relatively large, minimizing the impact of the sound source on the sound quality test.

The first is "ferry", the people of Pamu Z1 show unexpectedly, the Cai Qin voice is very full, PAMU Z1 has made the Cai Qin’s voice, but it is a pity that the low frequency is not enough; then "Hotel California" The dynamic range performance is good, the sound is clear, but there is a small problem, the whole sound area is not enough, it feels a bit flat.

However, as a real wireless noise reduction Bluetooth headset, I think there is no nice, after all, a 1999 fruit headset is also white. But I still emphasize that the sound quality is very metaphor, and the understanding of music varies from person to person. It is recommended that you can go online or buy a pair of earphones really hear.

Pama app experience, EQ sound, low latency, OTA upgrade firmware, personalized buttons set, etc., this is the mainstream. There are still quite a few places for setting adjustments.

Finally, it is the end of life, and the official claims to turn on noise reduction mode, single-line is 6 hours.

Test conditions: Headphone full power start test The number of middle numbers.

After the measurement, the renewal time after the noise reduction mode is opened, and the time is very close to the official declaration time. In the case of volume and weight control, such a battery life is generally satisfied. The life of the true wireless Bluetooth headset is very important consideration, which is more important than the sound quality.

Summary: As a truthless wireless active noise reduction Bluetooth headset, I think I really have no picky, he almost gives you the price of this price, and the entire battery life of Pamu Z1 is It is also possible to satisfy everyday use. If you are a user who is not enough, you may feel that there is no need to put too much money in your headphones, pursue a good use, then Pamu Z1 is a good choice.

You can see that I am praise this headset, because it is so ugly? Of course, it also has some problems but when I think it only needs more than 300, I have the highest 40DB noise reduction depth, Bluetooth 5.2, and IPX4 dustproof waterproof, enough sound quality and good look, I think there is nothing good. picky. Why is it so strict for all things? It is a very reasonable thing to get out of price.
