Many people may have seen it in science fiction movies. Driverless cars are soaring in the sky. Today, this scene has already been realized in half, and the era of unmanned driving is approaching.
On July 5 of this year, at the Baidu AI Developer Conference, Baidu CEO Li Yanhong was riding a Baidu and Bosch together to develop a self-driving car based on Apollo technology on the way to and from the venue. This is Baidu's attempt to combine artificial intelligence, maps, and big data. Of course, there are still some imperfections in the process of driving. However, these can be improved through future technological innovations.

In addition, China’s unmanned subway has been opened in the HKSAR at the end of the 13th. It is reported that as the company’s first unmanned project to operate in the Hong Kong market with the highest international technical requirements, it has successfully developed the product. It is of great significance for CRRC to develop the domestic and international unmanned metro vehicle market, and has also created favorable conditions for CRRC's future entry into the international market.

This group of driverless trains is composed of 3 sections and the maximum number of passengers is 1,500. The appearance is similar to that of an ordinary subway. There is no cab. This kind of new car will not require the intervention of drivers and crew members, and can automatically wake up the train. Automatic departure from the station, up and down the slope, accurate stop at the station, automatic opening and closing the door and other operations.
Of course, unmanned driving technology is not the first of its kind in China. As early as the 1970s, developed countries such as the United States, Britain, and Germany began to conduct research on driverless cars and achieved major breakthroughs in terms of practicality and feasibility. China began researching driverless cars only since the 1980s, and it was first developed by the National University of Defense Technology in 1992 to successfully develop the first truly unmanned vehicle.
In the United States, Google has also started this project long ago. In 2005, they used their own unmanned cars to take part in the second Grand Challenge competition organized by the US Department of Defense Advanced Research Projects Agency (DARPA). The car traveled more than 132 miles (212.43 kilometers) in the desert. ), so it won a $2 million prize from the Pentagon.

Although China's unmanned equipment started late, it has now completely caught up. Apart from unmanned vehicles, unmanned subways, and unmanned buses (chicken trains), they have achieved good results. Recently, they are preparing to build unmanned high-speed trains. .
According to He Huawu, academician of the Chinese Academy of Engineering, deputy chairman of the China Association of Science and Technology, and special technical consultant of the General Manager of the China Railway Corporation (referred to as China Railway Group), China is testing and verifying unmanned high-speed trains.
At the 14th China International Modernization Railway Technology and Equipment Exhibition held on October 26th, He Wuhua stated that at present, China’s high-speed rail has already taken the lead in the world, as a “China’s standard EMU train with independent intellectual property rightsâ€. "There is 84% ​​of the important standards for Chinese standards. The next step is to drive the high-speed rail unmanned."
Compared to driverless cars and unmanned subways, the environment faced by driverless high-speed rails is more complex, and the mileage is longer. It also has to face the sudden extreme environment at high speeds. He Wuhua also said that China's unmanned high-speed train can achieve "unmanned driving, someone on duty," from the current people-oriented, into a machine-based, so that high-speed rail operation is more secure and punctual.
In addition to China, Australia also uses unmanned railway technology. Driverless railways will reduce labor costs and increase operational efficiency. According to a French media report in June this year, TGV, a high-speed railway line operated by the French State Railway Administration's SNCF, plans to begin testing unmanned trains in 2019. These trains are equipped with sensors for detecting obstacles, detecting and judging dangers at any time, and carrying out emergency braking. At the same time, drivers on the trains will still be equipped with guards to cope with emergencies.
China's driverless technology has become more and more mature. In the world, it has already reached the forefront of most countries. The rapid development of driverless technology has also further improved our industrial standards and artificial intelligence.
Maybe in the near future, everyone will not need a driver's license. If they buy a car, they can use the unmanned technology to get on the road and traffic accidents will be greatly reduced. By then, it will be a further step away from the great rejuvenation of our country.
Nd Ce Yag is a yellow crystal. (Nd, Ce): YAG laser rod is by far the most ideal laser working material for solid-state lasers. It has high efficiency (20% to 30% higher than Nd: YAG efficiency) and low threshold , Anti-ultraviolet radiation and other characteristics. Nd Ce Yag is widely used in laser rangefinders, laser-induced military lasers, laser welding machines and other industrial applications, as well as laser medical, beauty and other fields.
