Countercurrent 1982

"Very good." Duan Yun nodded in satisfaction upon hearing this.In fact, regarding the current construction of the heavy truck base in Shenyang, Duan Yun has been closely involved. Almost every week, Duan Yun can receive the progress of the base construction from Shenyang, including the construction of the foundation.

How deep the wall is, how much the wall has been completed, and even how many bricks were used, all will be reported to Duan Yun in detail in the form of a report.It can be said that in the current Tianyin Group, in addition to the construction of the e-commerce logistics network, the heavy truck base in Shenyang is the largest project invested by the group company, because it is related to the next few years or even ten years.

There is no room for any mistakes in the layout of the industry.Fortunately, the person in charge here, Chen Qiao, is quite capable. Faced with such a large project, Chen Qiao performed with all his heart and responsibility. He lived up to Duan Yun's expectations for him. His daily work schedule was full. research
The development center is either at the construction site of the heavy truck base, and at night, he has to come out to entertain for the company and unite with Tianyin Group's dozens of automobile industry-related affiliates in Shenyang.

Generally speaking, Duan Yun is very satisfied with the current development of Shenyang's automobile industry, and some aspects have brought unexpected surprises to Duan Yun.

In fact, Duan Yun came to Shenyang this time. Apart from visiting the construction of the heavy truck base, he also has another important purpose, which is to test drive a sedan newly developed by the Shenyang Automobile R&D Center.Tianyin Group has always been at the forefront of automobile research and development in China. In the early years, through the introduction of Volvo production lines and equipment, it mastered some cutting-edge automobile technologies in developed countries in Europe and the United States. Later, through cooperation with SAIC, it absorbed After assimilating the technology of some gearboxes and other components of Volkswagen, and after accumulating related technologies to a certain extent, Duan Yun finally started his own curve overtaking plan.

It took more than 10 years for the whole process from imitation to transcendence.In fact, compared with the automobile industry in developed countries, China's automobile industry as a whole is still relatively backward. This is also inevitable. After all, Europe and the United States have experienced more than a century of development before today's automobile technology
It is almost impossible for domestically-produced cars to achieve a comprehensive lead in technology for decades.However, Tianyin Group has created a miracle in this respect. After more than 10 years of accumulation, Tianyin Group's machining level has reached the top level in China, and its electronics and machining technology are even comparable to

Of course, there is still a gap of about 3 to 5 years between the mainstream level of the United States and the world's top level, but in the field of civilian automobile production, it is enough.

In addition, compared with other domestic auto companies, Tianyin Group has another huge advantage in entering the auto industry, that is, their electronic hardware and software technology.In fact, before the 90s, except for some top luxury brands, ordinary civilian cars rarely had electronic components. The most common electronic components were car recorders, instruments and various buttons.
Mechanically, the Japanese invented the car CD later, but in general, cars of that era used very few electronic components.Another point is that in that era, the reason why cars rarely used electronic components was due to cost considerations on the one hand, and because electronic components were far less stable than mechanical components. Under the influence of various extreme environments, electronic components are easily damaged and malfunction, so almost all manufacturers try to avoid using electronic components in cars to reduce the incidence of failure...

But with the development of the times, users have more and more requirements for the functions of the car, and at this time the electronic technology is getting more and more advanced, and the development is getting faster and faster, so there are more and more electronic components on the car, and by

It has gradually become the standard equipment of modern cars.In later generations, the automotive electronic control system is mainly divided into electronic control units, sensors and actuators. The electronic control unit is the brain of the automotive electronic control system. It synthesizes the electrical signals input by each sensor and the feedback electrical signals of some actuators. Analysis and processing, the sensor provides a reference voltage, and then outputs a control signal to the actuator. The core of the electronic control unit is a microprocessor, which usually uses a single

Chip machine, its functions are easy to expand, and its control precision is high.Four years ago, Tianyin Group was already developing the single-chip microcomputer of this electronic control unit. At present, it has made a sample. After two years of continuous upgrading and improvement, the current vehicle control unit has been compared.

Mature, and the next step, Duan Yun plans to install this system on new cars.In fact, in terms of performance, the core chip used by this single-chip CPU is only equivalent to the level of 286 chips, but this is enough for vehicle-mounted systems, and the most important thing for this type of vehicle-mounted single-chip microcomputer is to operate in extreme environments.
In addition, the optimization of the software does not require high chip performance, so it does not need the most cutting-edge chip technology, Tianyin Group can completely achieve large-scale self-production.In addition to the electronic control unit, the automotive sensor is also a crucial part. The sensor is the clairvoyance and ear of the automotive electronic control system.

The theoretical parameters are converted into electrical signals and sent to the electronic control unit, so as to realize human-computer interaction, so that the driver can know all aspects of the vehicle at the first time.

These electronic sensors are divided into many types, such as pulse sensor potential, potentiometer sensors, thermistor sensors, and contact switch sensors.In Shenyang's Automobile R&D Center, there is a special project team responsible for the development of various sensors for automobiles. At the beginning, it did encounter some difficulties, but since the end of last year, the project team has achieved

A series of major breakthroughs have been made, and a series of automotive sensors with independent intellectual property rights have been developed, and international patents have been registered.

In addition to these electronic sensors, Telling Group's other major breakthrough in the automotive field is the development of vehicle navigation systems.Many years ago, Duan Yun has always attached great importance to the research and development of car navigation systems. At the beginning, he cooperated with Volvo and jointly developed a car navigation system based on GPS system. However, this product is limited by GPS. The civilian positioning accuracy of open navigation is not high, and the error can even reach tens of meters or even tens of meters. In addition, this car navigation system is expensive, so it cannot be put into large-scale use at all.
