Canada in December is already icy and snowy, the lowest temperature in Montreal can reach below minus 30 degrees, and on the other side of the ocean, Hong Kong is located in the subtropics, the temperature is much warmer than Canada, although Hong Kong in December is a little cold, but you only need to wear a coat to get it, unlike in Canada, wrapped up and down like zongzi.

Ling Shizhe has a deeper understanding of high-latitude and low-latitude regions, when he got on the plane from Canada, he wore a thick winter coat and cotton pants, and after getting off the plane in Hong Kong, he had to take off the winter night cotton pants and change into a single coat.

The advantage of owning a private jet is that you can adjust your departure time according to the time difference between the two places and the flight hours of the aircraft, so that when you reach Hong Kong, it is exactly at night, so that the adjustment of the time difference is in tune with the person's biological clock.

Back at Repulse Bay Villa, it was already 10 o'clock in the evening, and after more than ten hours on the plane, Ling Shizhe was already tired, did not speak, cooked a bowl of somen noodles with his own hands, took a bath in the bathroom, and went to bed, and snored after a while.

At half past six the next morning, the biological clock woke him up, opened the curtains and the morning sun shone in, Ling Shizhe took a deep breath, the refreshing air walked around in his lungs and then exhaled, feeling that the whole person was refreshed.

Well, it's a good day, and it should be a good sign.

Hong Kong people are very superstitious, everything has to talk about feng shui, although I know that this is a typical speculative psychology at work, but after living in Hong Kong for a long time, Ling Shizhe will be somewhat affected.

Today, he is going to cut the ribbon for the opening of Hong Kong's first MTR, Kwun Tong to Shek Kip Mei, and the Governor MacLehose will also be there to cut the ribbon, so he can't get up too late and must be there before the Governor comes.

After running around the villa twice, after doing radio gymnastics, I was already sweating profusely, I changed out of my morning training clothes, went to the bathroom to take a shower, and changed into a suit worn on formal occasions. After breakfast, the time had already pointed to half past eight.

After reading today's newspaper, at nine o'clock, Ling Shizhe got in the car and drove towards Kwun Tong.

It was already 10 a.m. when I arrived at Kwun Tong MTR Station. After Ling Shizhe got out of the car, he found that it was already crowded with people, so Lin Wencong separated the crowd and took Ling Shizhe to the rest area.

After another fifteen minutes, Hong Kong Governor MacLehose came, and at this time, Ling Shizhe signaled that Lin Wencong's ceremony began.

The DL-026 metro bus is painted in beige and dark sea blue. The front of the car is engraved with the eye-catching red and white Ambrera umbrella logo, the passenger car slowly drove to the platform, after reaching the designated position, the deafening firecracker sound suddenly sounded, Hong Kong Governor MacLehose, Hong Kong Financial Secretary Jin Delong (a ghost old man), MTR Corporation CEO Lin Wencong, Ambrera Transportation Equipment Manufacturing Company CEO Navalli, Ambrera Vice President and Hong Kong General Manager Andy. Grove and Ling Shizhe picked up scissors and cut the red silk hanging several meters long at the port of the carriage.

Ling Shizhe almost didn't have fun looking at the lively scene in front of him. Lin Wencong did all this, it is too similar to the set of the mainland, but it is a pity that it is a bit for the blind to see, he did not expect that Hong Kong Governor MacLehose did not even say a word when he came, and directly entered the ribbon-cutting ceremony, and as soon as the ribbon-cutting was finished, he waved to everyone and first stepped into the subway car.

This kind of ritual, which is completely different from the mainland, made him unable to adapt to it for a while. But it doesn't matter, seeing that everyone's faces are used to it, he just follows suit.

When everyone got into the train, it was half past ten. The train started and slowly drove out of the platform.

After the bus drove for a while, the Governor turned his head, looked at Ling Shizhe beside him and said, "Ling, I feel a little different from the bus I used to sit in. ”

Ling Shizhe smiled: "That's different? ”

"It's very quiet." MacLehose said.

"That's right, Mr. Governor, the noise of this train is very small." Navalli, who was sitting across from him, said: "This is our latest subway bus. The vehicle adopts a split power layout, focusing on low noise, low energy consumption, high reliability and high maintainability. The motor of the bus is the latest low-noise permanent magnet DC brushless motor developed by our Ambrera company, which not only has low noise, but also has very low energy consumption, less than half of the ordinary subway motor. In addition, the bus also adopts our company's latest development of the train digital power management system, so that the energy consumption of the bus has been reduced by half on this basis, and we have adopted a new type of soundproof doors and windows, which is why you feel very little noise. ”

"Nice bus." MacLehose praised.

Navali spoke again, and continued to promote to MacLehose that the DL-026 subway bus adopts those advanced technologies, how energy-saving, how durable, and how convenient maintenance and repair are.

Obviously, Navali is a very good salesman, he understands the customer's heart, under his skillful publicity, the people around not only do not feel bored, but also listen to it with relish, everyone has a great interest in this train, especially the surrounding reporters are even more excited, Navali pops out of the mouth of the professional vocabulary they don't understand, but it doesn't matter, as long as they feel that this passenger car is very advanced, very tall on the line, as long as these reporters have this concept in their hearts, They themselves will help you get the word out in the newspapers.

But as a veteran politician, MacLehose is obviously not so easy to fool, he patiently listened to Navali talk a lot, and said: "With so many new technologies, buses must be very expensive, right?" ”

"It's not expensive at all. The price of a passenger car is only 20% higher than that of a regular bus. Navali said proudly, "So I'll take you to the cab to see it first." ”

Coming to the cab, MacLehose was shocked, this ...... It's just too sci-fi, the whole cab is like the cockpit of the advanced passenger plane of later generations, and there are five CTR gray displays neatly arranged in front of the train driver, which displays all the running data of the train, and these data have also been visualized and processed by technology, so that the train driver can understand and understand at a glance.

And the operation of the train is also very simple, the fly-by-wire control system, greatly reduces the burden of the train driver, the general subway passenger car needs two drivers, and this passenger car only needs one driver to OK.

MacLehose is really moved now, he still knows a little about the subway, such an advanced subway bus is really only 20% more expensive than ordinary subway buses in terms of price, then in the international subway bus market, the competitiveness of this bus is not a little bit.

He attended the ribbon-cutting of the new Underground bus in London in July, and he remembers well that there was not as much new technology on the bus as it was. But the price is several times that of an ordinary subway bus, but what about this bus? The new technology is obviously a lot higher than London's new Underground, but it's so affordable that it will certainly be favored by some Underground operators. By then, Ambrera will definitely be rich again.

The so-called visualization technology comes from the big data traffic of the network in later generations, and in the network era of later generations, the large amount of data generated by a wide variety of information sources is far beyond the ability of the human brain to analyze and interpret this data, because the vast majority of people are not professionals. For computers, they will only use them, so in order to facilitate people's use, big data visualization technology came into being.

Alibaba, Tencent, and Amazon are the leaders of visualization technology!

As long as the construction of the basic data platform is completed, and the data indicator system is standardized, uniformly defined, and dimensionally distinguished, it is very convenient to carry out standardized configurable data report design and intuitive visual output design. This includes multiple data categories such as behavior, revenue, performance, quality, and more.

If there is no visualization technology, then the bill list we see now is no different from the consumption bills of commercial banks and credit cards - that is, it is obscure and difficult to understand!

And with visualization technology, all the complicated and boring data, through the computer classification and sorting, has been most people can understand the way, intuitive display in front of people's eyes, people only need to look at it, to know what is the speed of the bus, whether the motor temperature is in the normal range and so on. What is the rotational speed, whether all the doors have been closed, etc., all the data during the operation of the train are intuitively displayed on the display.

Of course. Subject to the computer hardware technology of this era, Ling Shizhe made this set of visualization a lot simpler than later generations, but the basic principle is still the same, the bus operation data displayed on the display screen should be basically there, the only difference is that the display screen of later generations uses a color LCD screen. And the monochrome CTR display used in this train of buses, and the image displayed is a bit rough, not as refined as later generations.

But even such a crude visualization technology is shocking enough in the eyes of people in this era.

Product and operation analysis, based on the data platform and visualization, conducts various analyses on existing user behavior and revenue data, and outputs daily, weekly, monthly, and various special analysis reports. Like what. User portraits are also a common data analysis method, including users, such as gender, age, behavior, income, hobbies, consumption behavior, online behavior, channel preferences, behavioral preferences, life trajectory and location, etc., reflecting various characteristics of users to achieve a comprehensive understanding of users. Targeted for the purpose of providing users with personalized services, etc.

Refined operation platform. The refined operation platform built on the basis of data is mainly for user segmentation. Segmentation of goods and services, personalized recommendation of goods and services through the combination optimization of multiple recommendation algorithms. In addition, there is a product data operation system built for different product life cycles and user life cycles.

There are a lot of data products, data products in the broad sense. For example, Tencent's Guangdiantong and carrier pigeons; Alibaba's data cube, Taobao intelligence, Taobao index, in the cloud; Baidu's Baidu Forecast, Baidu Statistics, Baidu Index, Baidu Sinan, Baidu Actuarial Science, etc.

Finally, strategic analysis and decision-making, which is similar to many traditional strategic analysis and business analysis methodologies, the biggest difference is that the data comes from the big data of the Internet.

The above are the basis for the operation of visualization technology, the simple visualization system applied on the train, naturally can not escape the above several basic technology platforms, in order to realize it, Ling Shizhe used the United States 1553 data bus.

In the eighties, the traditional automation is moving towards the intelligent automation with integrated circuits as the core, in the process of this transformation, the network bus connecting the various branch systems has become very important, in the later generations, small to automobiles, home appliances, large to aircraft and ships, the electrical components that control their various classification functions are connected together through the built-in system bus to form a complete whole.

If intelligence is compared to a person, then the sensing component is the nerve endings of human beings, and people use it to sense things in the outside world, whether this thing is solid or liquid, cold or hot. They all perceive the world through nerve endings, and computers are like human brains, but in order for the brain to sense the outside world, a nerve wire is needed to connect the two, and if the wire is broken. The brain doesn't react to anything outside, and the 1553 data bus is this nerve.

At the beginning of the absolute development of the engine digital control system, Ling Shizhe wanted to get out the 1553 data bus of the United States, but after a period of time, Ling Shizhe gave up.

Why? Because of the 1553 data bus. Although it is the most basic thing in the IC industry, it is something that can only be made by relying on the power of the whole country and long-term accumulation, and ordinary people can't make it at all.

Fortunately, the 1553 bus in the United States has begun research and development in the 60s, and in 1971 the results were produced and made public, otherwise Ling Shizhe wanted to achieve primary digital control and management in the 70s, and he could only hehe.

When he first got on the train, MacLehose just thought of the DL-026 as an ordinary subway bus, but now he has circled around the entire carriage. It was discovered that this new light rail train was not simple at all - the whole train was automated.

The automation of the whole train is divided into two parts, one part is to make a fuss about the degree of luxury that is relatively easy to achieve, such as the automatic door of the train and the automatic sensor lights installed on the roof, etc., the real power is the invisible automation of the whole train monitoring system and the whole train control system, if you don't come to the cab to see it, MacLehose will not know, this is a fully chip light rail train.

"Ling, how did you achieve this?" The shock that this light rail train brought to MacLehose's psychology was not ordinary, so he very much wanted to know how Ling Shizhe did it, although he knew that the questions raised might involve other people's technical secrets. But for some reason he just wanted to know.

"Sensing components, 1553 two-way data transmission bus, trip computer ECU, comprehensive analysis computer, electronic controller system, and several related software, is the automation solution for the whole bus, and the cost of this solution is very low." Of course, Ling Shizhe would not tell the other party the core secret. But what he confided was enough for the other party to understand.

Since the day the republic was founded, it has been strictly blockaded by Western countries, even after Batumi was abolished, and with the increase of the national and economic strength of the republic, the technological blockade of Western countries has become more and more severe.

In this case, the republic wants to achieve four modernizations. You're on your own.

The semiconductor industry of the Republic is not a little bit behind the Western countries, but a gap of several decades, and it is conceivable how difficult it is to achieve industrial automation in this extremely unfavorable situation.

It is in this extremely unfavorable situation that the scientists of the Republic have not only realized industrial automation by virtue of the technology that has lagged behind the West for many years, but also the comprehensive technical level is not much worse than that of the Western countries, and the cost is also very low.

The phased array radar and advanced digital flight cockpit of the Republic are the most typical representatives!

After a long period of exploration, the Republic has come up with a set of self-contained industrial digital system solutions, which are stable and reliable, have good compatibility, strong adaptability to extreme environments, strong anti-interference ability, and outstanding performance, and more importantly, its cost is as low as the cabbage sold in the market.

Ling Shizhe has been engaged in this work for a long time in his previous life, so he is no stranger to this digital system solution of the Republic, which is also the fundamental reason why he dares to pile so many new technologies on the train, not only outstanding performance, but also quite low cost.

MacLehose went to London to see the new light rail train, which is available on the Toronto subway in Canada, and Ling Shizhe also went to see it himself.

After reading it, Ling Shizhe was very disappointed, this light rail train is the latest product developed by the French TGV company. How so? In Ling Shizhe's opinion, this thing is simply a scum, his automation is only a little better than the DBme bus in East Germany, but the complex structure and high manufacturing cost make this kind of bus extremely difficult in terms of maintenance and maintenance.

The DL-026 does not have this problem, it uses the automation solution of the Republic of the future, whether it is in terms of performance, reliability, price, and economy.

Ling Shizhe is full of great hope for this light rail train, as long as it passes the actual operation test of the Hong Kong subway, I believe that orders will continue to fly, so that Ling Shizhe counts the money and counts the cramps. (To be continued.) )
