Super Copy of Great Power Technology

"We don't use 3G mobile phone network. For this live broadcast promotion, we specially applied for permission to use the satellite network, modified a RV, and installed a satellite communication antenna on the roof. With the satellite network, the live broadcast effect is still good Guaranteed." A staff member in charge of logistics introduced, pointing to the white mushroom-head satellite antenna on a RV.

"Well, it's poverty that limits my imagination. If you use a satellite network for live broadcast, the bandwidth will definitely be no problem, but the delay may be higher, but as long as you reduce the interaction with netizens, it won't be a big problem."

Satellite communication is not a high-end technology. As early as the end of the last century, a communication company in China developed an Iridium satellite phone, which can make satellite phone calls anywhere in the world. However, the communication cost is too high and has not become popular. The time has come to 2012. After several rounds of updates and iterations of satellite communication technology, it is not difficult to use satellites for network data transmission. The problem is that the cost is too high and ordinary people cannot afford it.

Next, the staff member took Fu Xiaoyi to familiarize himself with the photography equipment and prepare for the afternoon shooting and live broadcast. And Fu Xiaoyi lives up to expectations. He is very proficient in operating the camera, and the materials he shoots casually are also quite skillful. Moreover, he can also operate a computer, understand the use of editing software, and can perform simple video editing and processing. Fu Xiaoyi, who was regarded by everyone as uneducated and unskilled, was also a talented person, but what he was good at was not learning or mechanics, but photography. Asking him to guard the gate of the security team was like a secret.

The maintenance work of all vehicles was completed at 11 o'clock in the morning. Then all the fuel vehicles were filled with oil and the trams were fully charged. Finally, a batch of food ingredients, snacks and beverages and mineral water were purchased and placed in the automobile factory. For everyone to use on the go. At this point, all preparations have been completed, and we are just waiting for all team members to be in place before we can set off.

After having lunch in the cafeteria, Qiao Ruida and Du Qingqing took a short rest and rushed to the test track. They gathered more than 30 team members, drove a dozen large and small vehicles, and set off in a mighty manner.

In a Roadster sports car in the middle of the motorcade, Qiao Ruida was driving while talking to the camera, "Dear viewers in the live broadcast room, good afternoon, everyone, I am Qiao Ruida. Maybe some friends who follow the automotive industry have already seen I have heard some news that our Ruida Automobile Factory, a subsidiary of Ruida Technology, will soon launch two new energy vehicles, one of which is MINIEV, and the other is the Roadster sports car I am driving now, which uses a four-wheel drive system. The on-wheel torque reaches a terrifying 10000 Nm, acceleration from 2.1 to 0 kilometers in 400 seconds, acceleration from 8.8 to 400 meters in 1000 seconds, a top speed of over kilometers per hour, and a cruising range of over kilometers.”

While Qiao Ruida was introducing, she motioned to Fu Xiaoyi, who was sitting in the passenger seat, to point the camera at the center console of the car and let the netizens in the live broadcast room take a look at the interior, instrumentation and vehicle systems of the Roadster sports car.

At this time, Du Qingqing, who was sitting in the back seat of the car, operating a laptop and responsible for pushing live streams and monitoring comments from netizens in the live broadcast room, suppressed his excitement and whispered: "The number of people online in our official live broadcast room, It has exceeded 100 million, and there are more than 50 on the YY live broadcast platform, and the number is still growing rapidly. "

At present, the domestic online live broadcast industry has just emerged, and YY Live Broadcast, as the first crab-eating platform, has only been established for four years. Due to limited network bandwidth, YY only did voice live broadcasts in the past few years. It was not until earlier this year that a camera was added and it was converted to video live broadcasts. In order to promote the live broadcast of this new car winter test, the company's publicity department specifically contacted the YY live broadcast platform, paid a fee of 20, and opened an exclusive live broadcast room. Of course, YY has been a live broadcast platform for a short period of time, and its hardware and bandwidth are not very powerful. The number of viewers it can carry is very limited, and 100 million is the limit. In order to meet the requests of more netizens to watch the live broadcast, Reda Technology has specially set up a live broadcast room on the official website. In this live broadcast room, viewers can post comments, leave messages, and send free flowers and applause, but there are no paid gifts or rewards. The account and password used to log in to the live broadcast room are interchangeable with Reda Pass and Reda Mall members. . With the support of Reda Technology's server cluster and unlimited bandwidth, Reda Technology's official live broadcast room can accommodate tens of millions of netizens watching the live broadcast at the same time, which is no big deal.

In order to improve the publicity effect, a few days before the live broadcast, people from the publicity department began to invest a large amount of money in advertising on the Internet to build momentum for today's live broadcast. The personal Weibo accounts of Ruida Technology and Qiao Ruida also released relevant information about the new car winter test live broadcast, and gave links to the official live broadcast room. As the domestic mobile phone manufacturer with the largest product sales, Ruida Technology is still very popular on Weibo, with more than 500 million followers. Thanks to the aura of the richest man, Qiao Ruida's personal Weibo account has become even more exaggerated. The number of fans has already exceeded 1800 million, reaching million, making him the number one person on Weibo. With the promotion and diversion of these two major Weibo accounts, it is not surprising that there are millions of netizens watching the live broadcast online.

Qiao Ruida controlled the car and turned on the automatic driving system of the Roadster sports car. Then he freed up one hand, took out his mobile phone, opened the official website of Ruida Technology, and then projected the phone screen onto the car screen and started browsing the live broadcast room. The comments and messages inside.

"Finally we see the richest man, Qiao, come and get rich."

"Classmate Qiao, are you bragging? A domestic car can accelerate from 0-100 in 2.1 seconds. Why don't I believe it?"

“+1 if you don’t believe it, I have driven a lot of sports cars. Million-level sports cars such as Porsche 911 and Lamborghini Da Niu can hardly accelerate from 3 kilometers to 2.5 kilometers in more than 2.1 seconds. Some tens of millions of supercars can reach kilometers. Acceleration of seconds is the top. Ruida Automobile has no background, and it is the first time to make a sports car. It can accelerate to kilometers in seconds. It is simply a fantasy. I don’t believe it anyway.”

"I see that you have never driven a new energy vehicle. Let me tell you that in the initial stage of the car, the torque of the motor is very strong, the acceleration is very fierce, and the feeling of pushing the back is very strong. It can be anywhere from 2.1 to years old. Wan's mid-range electric car can easily accelerate from kilometers to kilometers in three seconds. At high speeds, the performance of the motor is not as powerful as that of a gasoline-powered car. It is really possible to accelerate to kilometers per hour at . "Oh, what a big central control screen. It can display driving status, map navigation, and can also listen to music, watch videos, and provide simple entertainment. This is comparable to traditional fuel. The car smells better.”

"Have you just noticed that there seems to be some text information displayed on the front windshield? Is that a heads-up display? It looks so advanced?"

"Hey, have any of you seen clearly how the mobile phone screen is projected onto the central control screen? It seems that you are holding the back of the Ritar second-generation mobile phone and leaning against the central control screen, and the mobile phone screen is projected onto it. Okay. magic."

"Hey, hey, hey, classmate Qiao, you are driving, where are your eyes looking? Are you looking at the comments in the live broadcast room?"

"Yes, Richest Man Qiao, you must pay attention to driving safety, otherwise, tomorrow's newspaper headlines will be about your car accident."

Seeing the last two messages, Qiao Ruida couldn't help but smile knowingly and said: "Thank you for your concern, but you don't need to worry about driving safety. This Roadster sports car is equipped with at least an LV3 level autonomous driving system. After it is turned on, it can handle normal road conditions. It is more than adequate for driving work. As for the performance of this Roadster sports car, there is no doubt that the actual measured data is definitely better than the parameters and will not be worse than the parameters. After the team arrives in Mohe, a comprehensive review of the two new cars will be carried out. Performance tests include acceleration to 200 kilometers, acceleration to kilometers, shortest stopping distance, elk test, etc. You will know for yourself whether the performance parameters of the Roadster sports car are false.

I saw a friend asking how the screen of the mobile phone was projected onto the screen of the car. This is actually an ecological interconnection between our Reda mobile phone and the Reda car machine. It can be controlled by the mobile phone or NFC sensor to project the screen of the mobile phone onto the car screen. Even on the car screen, you can operate your phone, turn on the phone's camera, access the photo album, use the phone's signal to make calls, surf the Internet and other functions. As for the interesting linkage functions that can be realized, you can buy a Reda mobile phone and a Roadster sports car to explore on your own.

Oh, I seem to have forgotten to introduce to you the destination of our trip. Our fleet is currently rushing to Mohe City, the northernmost tip of mainland my country, where we will conduct winter cold resistance tests on two new cars. Car winter testing is mainly to verify the car's low-temperature starting ability in extremely cold weather, its handling performance and safety performance on ice and snow roads, to ensure that the vehicle can drive stably in harsh weather conditions. The main test items include startup test, insulation test, brake test, suspension system test, drive system test, etc.

As pure electric cars, Roadster and MINIEV both use lithium batteries as energy storage mechanisms and motors as power systems. As we all know, lithium batteries, whether lithium iron phosphate or ternary lithium, suffer from attenuation of storage capacity, reduced discharge capacity, and slower charging speed in severe cold weather in winter. Therefore, in this winter test of new cars, we will also test the degradation of battery life in severe cold weather and the changes in charging curves.

Okay, next, let’s conduct a battery life test under normal temperatures. The current state of our Roadster sports car is that it is fully loaded with four people, the air conditioning is turned off, the driving mode is high performance, and the energy recovery is the lowest. The CLTC standard cruising range of our Roadster sports car is 1050 kilometers, and the battery is 750v, 150kwh. Before setting off, we were fully charged. The current meter shows that the cruising range is 1100 kilometers. After setting off from the Ruida Automobile Factory, the running mileage is now 15 kilometers. Please keep this data in mind. During the journey, we will report the changes in the performance cruising range and the actual mileage at any time. Let's take a look at whether the cruising range of this Roadster sports car can reach the nominal 1000 kilometers. How much water does the 1100 kilometers of cruising range shown on the meter have?

Ruida Automobile Factory is located in my hometown, Decheng City. The route we are taking now is to start from Decheng City, take the Changshen Expressway, pass through the Jishuang Expressway, transfer to Shuangnen Expressway, and finally pass the G111 National Highway to reach the mainland of my country. Mohe City in the north. With a total driving range of 2300 kilometers, the Roadster I drove needed to be charged at least three times before it could reach the distance. As for MINIEV, another new energy vehicle developed by our company, it focuses on low price and has a cruising range of only 311 kilometers. I won’t show it here to show off. Now those MINIEV test vehicles are on the truck, enjoying the consignment service.

Okay, now we have reached the highway intersection and get on the highway immediately. Well, the road conditions on the highway are good. After coming up, the bumps are obviously reduced a lot, and the speed can be increased appropriately. Let's set it at 100 kilometers/hour. Friends who have driven a gas car must have a deep understanding of the changes in fuel consumption. Normally, when a gas car is driving at low speeds, and when commuting within the city, the fuel consumption is relatively high, reaching more than 10 gas per kilometers, which is common. . When running on the highway, fuel consumption will be much lower. It is common to consume five or six liters, or seven or eight liters per kilometers. This is because gasoline and diesel engines can maintain the highest combustion efficiency, the highest fuel conversion rate, and the most fuel economy only at high speeds. At low engine speeds, fuel combustion is insufficient, the conversion efficiency is relatively low, and fuel consumption is very high.

Our electric vehicles are exactly the opposite of traditional fuel vehicles. The faster they go, the more electricity they consume, and the slower they go, the more energy they save. In other words, it is most cost-effective to drive an electric car to commute, commute to get off work, and pick up children in the city. It is not impossible to pay four or five yuan per 950 kilometers of electricity. When running at high speeds, the cruising range of our Roadster sports car will be greatly reduced. The electricity bill per 100 kilometers will also be higher, reaching seven or eight yuan or even more than ten yuan, which is normal, but this is also much lower than the driving cost of a fuel vehicle. Please take a look at the remaining cruising range displayed on the central control screen. It has been reduced to kilometers. This is the result of the vehicle speed increasing to kilometers per hour. "

As the live broadcast continues, the number of people in the live broadcast room continues to increase. The number of people in the official live broadcast room is heading towards 200 million. The barrage has already covered the screen so densely that if the display of barrage is not disabled, you won’t even be able to see any live broadcast images. As a last resort, Du Qingqing modified the rules for posting barrages in the official live broadcast room, stipulating that the interval between posting two barrages for each user must exceed 30 minutes, and the situation became better.
