Following Chen Yanrui's feelings, everyone seems to have entered that era, even if they are excellent university professors, their material life is not necessarily comparable to that of an ordinary worker, and faith was the only thing that supported them. But as each year passes, beliefs may also tend to disintegrate.

"With the introduction of more microcomputers, various universities and research units have also carried out research and development work on microcomputer protection, but unfortunately, we are struggling, the English operation interface, the new programming language, we all need to learn, and the microcomputer is so expensive, we just got a model, the United States has been updated!"

"Originally, I had a second chance to engage in microcomputer protection in school, but it happened that other projects were pressed, coupled with the original teaching task, and I am older, it is more difficult to learn microcomputers, so this matter was shelved, I believe that Professor Li Minghe has the same troubles as me. ”

Chen Yanrui said, throwing a friendly smile at the professor not far away.

"Microcomputer, microcomputer. Li Minghe finally spoke slightly, his voice was a little hoarse, "This is what young people should do, instead of us occupying that baby with reading glasses and a finger of Zen, it is better to give them precious time on the machine, I am typing that little keyboard now, I can't see clearly." ”

After another friendly laugh, Chen Yanrui continued: "In this way, I missed another opportunity, and spent another four or five years, and in the blink of an eye, it has been the nineties, through Guò Professor Chang in the same college, I had the opportunity to contact Hengdian, and got to know Xiang Xiaofei Xiang Zong, during that time, she came to the school every day to block me, and hoped that I could participate in Hengdian's microcomputer project." ”

"This time, Mr. Xiang didn't intend to give me the time and space to hesitate, forcing me to have nowhere to hide, plus the preparation of Hengdian is really sufficient, when facing this opportunity for the third time. I finally took this step. Chen Yanrui said and looked at the prototype in front of him, "So, with the efforts of Chang Jiang and our entire project team, the EPR-866A model was finally born, which is not only a product." It is also the protection of China's microcomputer from scratch, I implore you to use the most professional eyes to examine it, the most demanding way to assess it. ”

After speaking, Chen Yanrui got up and bowed slightly to everyone on and off the stage: "Thank you for being here and witnessing the protection of my country's first real microcomputer." ”

The applause rang out, no one thought that this old professor, who was still teaching at the university more than half a year ago, could complete the opening remarks in such an emotional way, if this device could really run steadily, then everyone underestimated the historical significance of this appraisal meeting in advance.

"Is he really a professor, is he from the acting department?" Hua Changqing in the audience was full of ridicule. "If you have this time, you might as well introduce the parameters clearly. ”

Zhang Yifu was noncommittal, he didn't feel that Lao Chen was performing, and the slight tremor in the old professor's voice showed the excitement in his heart.

Chen Yanrui especially boasted about the laboratory table, which has reached the world-class level in terms of speed, sensitivity, reliability and safety.

In this product identification, it is impossible to disassemble the device to see, and all discussions must be based on the test report of the Electric Power Research Institute. When this report was sent to everyone, everyone found out that Chen Yanrui was not half exaggerated.

This time, the Electric Power Research Institute carried out the dynamic model test and type test of 866A respectively. The dynamic model test is the dynamic simulation test of the power system, which tests the functions, technical indicators and credibility of the device, while the type test is biased towards the hardware of the device, considering whether the process standard is enough or not, under the specified environmental conditions, such as temperature, atmospheric pressure, vibration, etc. Does its work remain stable...... In fact, the type test is only needed before the final production, but in the end, the method is still exhausted and the electric power research institute is entrusted to carry out the test evaluation, because Hengdian is full of confidence in the dynamic model test results, since the test must solve all problems in one go.

The people present are all engaged in professional technology, so they are naturally more concerned about the results of the dynamic model test.

The dynamic model test was also divided into three levels. The test is carried out on the transmission lines of 500KV, 220KV and 110KV, which basically covers the three most standard voltage levels of China's power grid at this time. Transient beyond more than 10 categories, in a variety of wiring methods and transmission environments, 866A has undergone thousands of test investigations, in a harsh and complex environment, whether it can respond to all faults and abnormalities, how long the reaction time, these two indicators will be the most important test results.

In addition, it is worth mentioning that, unlike the digital simulation test environment built by Hengdian itself, the test of the Electric Power Research Institute is a physical dynamic model test, which is driven by real current and voltage, rather than a digital signal, which undoubtedly also actually tests the performance of the product A/D conversion.

Get dozens of pages of test reports, everyone has to double first, this professional report has many charts, but also contains a lot of incomprehensible recording charts, the real text description is very little, completely for professionals to see.

In half a minute, Jia Luansong on Zhang Yifu's right was still forcibly understanding, and Hua Changqing on the left had hurriedly turned more than a dozen pages, and he couldn't stop muttering "um" and "ah" in his mouth.

Before the conversation started on the stage, Hua Changqing's face was already full of incredulous expressions, and he turned his head and said: "Yifu, I believe in the authority of the Electric Power Research Institute, but are you sure that this device was not brought back from abroad and re-labeled?"

"What do I want to buy at twice the price and sell at half the price?" said Zhang Yifu.

"I've seen quite a few of these academic scammers. Hua Changqing clenched the test report, and did not want to believe these numbers in his heart, although it was just a relatively simple microcomputer circuit protection, but it could be made from scratch in such a short period of time, he did not believe that a person could do it without relying on external forces.

"Hehe, you can think I'm an academic liar. Zhang Yifu pouted at Chen Yanrui in front of the stage, "But what about him? Do you think Professor Chen is cheating? Brother Hua, you are also a graduate of the Electric Academy, right?"

"......" Hua Changqing was speechless, and then he remembered that the nominal main researcher was Chen Yanrui, damn this kid is too smart, with such a Shifo town, no one dares to question Hengdian.

This is the Institute of Electrical Engineering, not the Society of Electrical Science, emphasizing the word engineering, and the people who come are all engineers, and the only thing they believe in is the results of the experiment, not the fanciful theory. (To be continued......)
