Following Chen Yanrui's emotions, everyone seems to have entered that era. Even an outstanding university professor may not be as good as an ordinary worker in material life. Belief was the only thing that supported them. But as a dull past year by year, belief may also tend to collapse.

"With the introduction of more microcomputers, various colleges and research institutions have also started research and development of microcomputer protection. Unfortunately, we are struggling. We all need to learn the operation interface in all English and the brand new programming language. Microcomputers are so expensive. As soon as we got a model, the United States has been updated!"

"Originally, I had a second chance to do microcomputer protection at school, but other projects happened to be suppressed. Coupled with the original teaching tasks, I was older and it was difficult to learn microcomputer, so this matter was put on hold. I believe Professor Li Ming and I have the same troubles as me."

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

"Microphone, microcomputer." Li Minghe finally spoke slightly, his voice a little hoarse, "This is what young people should do. Instead of occupying the baby with reading glasses, it is better to give them the precious time to board the computer. I can't even see clearly when I typed that little keyboard now."

After another friendly laughter, Chen Yanrui continued: "In this way, I missed another opportunity, and spent another four or five years. In the blink of an eye, it was already the 1990s. Through Professor Chang, who was also in the college, I had the opportunity to contact Hengdian and met Mr. Xiang Xiaofei. During that time, she came to the school every day to block me, hoping that I could participate in Hengdian's microcomputer project."

"This time, Mr. Xiang did not intend to give me time and space hesitation, forcing me to have nowhere to hide. In addition, the preparations for the Continuous Electric were sufficient. When facing this opportunity for the third time, I finally took this step." Chen Yanrui said as he looked at the prototype in front of him, "So, with the efforts of me, Chang Jiang, and our entire project team, the epr-866a model was finally born. This is not only a product, but also a microcomputer protection from my country. I urge everyone to examine it with the most professional perspective and evaluate it in the most demanding way."

After saying that, Chen Yanrui stood up and bowed slightly to everyone on and off the stage: "Thank you for being there and witnessing the protection of our country's first real microcomputer."

Applause rang out, and no one expected that the old professor who was teaching at the university more than half a year ago could complete his opening remarks in such an emotional way. If this device could really operate stably, then everyone underestimated the historical significance of this appraisal meeting in advance.

"Is he really a professor? Is he from the performance department?" Hua Changqing in the audience was full of teasing. "It's better to introduce the parameters clearly if you have this time."

Zhang Yifu didn't agree, he didn't think Lao Chen was performing. The slight trembling in the old professor's voice showed his inner excitement.

The following time begins a routine introduction. Functional summary and technical parameter range are read one by one. Chen Yanrui especially boasted about the laboratory performance, and its speed, sensitivity, reliability and safety have reached the world's first-class level.

It is impossible for everyone to take apart the device for this product identification. All discussions must be based on the experimental report of the Academy of Electrical Sciences. When this report was posted to everyone, everyone discovered that Chen Yanrui had no exaggerated elements.

This time, the Academy of Electrical Sciences conducted dynamic mode tests and type tests on 866a, namely dynamic simulation tests of the power system, testing the various functions, technical indicators and credibility of the device. The type tests are biased towards the device hardware, considering whether the process standards are sufficient, and whether the work remains stable under specified environmental conditions, such as temperature, atmospheric pressure, vibration, etc.... In fact, the type tests are only needed before the final production, but in the end, they still used all methods to entrust the Academy of Electrical Sciences to conduct an experiment and evaluation. The reason is that the Chang Electrical Sciences is full of confidence in the results of the dynamic mode test. Since you want to test, you have to solve all problems in one breath.

Everyone present is engaged in professional technology, so they are naturally more concerned about the results of the mold-moving test.

This dynamic mode test is also divided into three levels, respectively, on transmission lines of 500kv, 220kv and 110kv. This also basically covers the three most standard voltage levels of my country's power grid at this time. The specific test items include more than ten categories such as action time measurement, metallic failures inside and outside the zone, transient transient transcendence, etc. In various wiring methods and transmission environments, 866a has undergone thousands of tests. In the harsh and complex environment, whether it can react to all fault abnormalities and how long is the reaction time? These two indicators will be the most important test results.

It is also worth mentioning that unlike the digital simulation test environment built by HangDen itself, the test of the Academy of Electrical Sciences is a physical dynamic mode test, which uses real current and voltage to drive, rather than digital signals, which undoubtedly actually tests the performance of the product a/d conversion.

After getting dozens of pages of test report, everyone has to double it first. This professional report has many charts and contains many difficult-to-understand recordings. There are very few real text narratives, which are 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 already flipped through more than a dozen pages, and couldn't help but murmur like "Yeah" or "ah".

Before the chat started on the stage, Hua Changqing's face was filled with incredible expressions, and he turned around and said, "Yao, I believe in the authority of the Academy of Electrical Sciences, but are you sure that this device was not brought back from abroad and posted a sign again?"

"What am I trying to do? Buy it at twice the price, and then sell it at half the price?" Zhang Yifu was both amused and sarcastic.

"I have seen many such academic scammers." Hua Changqing held the test report tightly, unwilling to believe these data from the bottom of his heart. Although it was just a relatively simple microcomputer line protection, he did not believe that a person could do it without relying on external forces.

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

"..." Hua Changqing was speechless, and then he remembered that the nominal main researcher was Chen Yanrui. This kid was so smart. No one dared to question Hengdian with such a Shifo.
