"A set of large-scale air-conditioning equipment and sprinkler irrigation equipment, the investment is not smaller than that of a planting greenhouse, your courage is not small!" Li Xuan smiled at Chen Tao, who was beside him. @頂@点@小@说,

It was under Li Xuan's instructions that the Oriental Research Institute installed a computerized control system for Chen Tao in one step, instead of the rudimentary temperature alarm device he had originally planned.

The real power of AIPC-100 calculations is when the computer receives the number of jù sent back by the temperature sensor and finds that the temperature in the greenhouse exceeds 25 degrees Celsius. The computer program will automatically turn on the air conditioning equipment to cool the greenhouse. Similarly, the computer will automatically sprinkle the roses in the entire greenhouse at a fixed time every day according to the program set by the administrator in advance.

This was an ordinary technology on the street 30 years later, but in 1982, it was already a great high-tech. In order to achieve this ability, it is natural that Chen Tao, the owner of the greenhouse, needs to invest in the purchase of corresponding air conditioning and sprinkler irrigation equipment.

"My wife and I used to travel to Malaysia and found the rose garden there to be very beautiful. Hong Kong consumes a lot of roses every year, but it does not have its own flower planting industry, so it needs to import a large number of roses every year. I think it's an opportunity and I'm ready to give it a try!"

Chen Tao began to talk about his entrepreneurial history, "I have collected information and found that the summer in Hong Kong is too hot, which is not conducive to the growth of roses, and it is easier to control the quality of flowers only by adopting greenhouse farming!

Originally, my father did not approve of me continuing to expand my investment, but my grandfather agreed. He said, Mr. Li, since you are willing to provide advanced technical support. There's no reason not to give it a go!"

The Oriental Research Institute's acceptance of Chen Tao's automation transformation project of the planting greenhouse is naturally for the sake of Chen Xinli's face. Otherwise, how could the Oriental Research Institute be interested in taking on such a small project. In order to achieve temperature control and irrigation automation. Dongfang Software has also developed a special application applet.

If the Chen family is unwilling to invest, Li Xuan will not need to spend these troubles. Just ask someone to get him a temperature alarm. But Chen Xinli's courage is still enough, and Chen Taotong guò gu�

In this case, Li Xuan is also willing to spend some energy to make this project a model project, as a business card for the future promotion of AIPC-100 industrial control computers in Hong Kong. AIPC-100 is a general-purpose industrial control computer, suitable for the automated production needs of many factories, and the scope of application is not limited to such a small temperature-controlled greenhouse.

"I may need a larger number of roses for my May wedding. If you can supply it here, I don't need to import it from abroad!" Li Xuan said, this was the main purpose of his visit today.

"Li Sheng, how much do you need? If it doesn't exceed 100,000 flowers, I can eat it here!" Chen Tao didn't say yes in a big bite, but asked cautiously.

"100,000 flowers should be enough, tomorrow I will call someone to come and contact you, whether it is enough or not, I will give priority to purchasing from you!" Li Xuan said with a smile, "Hong Kong's flower market is not small, if you do well, you can also grow other higher value-added flowers in the future." Like Phalaenopsis and the like. The Chinese New Year's Eve flower market in Victoria Park is popular every year!"

"Brother, in addition to red roses, there are also white roses and yellow roses here!" Li Ying held a bouquet of roses and walked over in a slightly surprised tone.

She picked out all the red roses in her hand and handed them to Li Xuan. I only have white roses left: "These are for you to please your second sister-in-law!"

Li Xuan chuckled and took the rose. The flower language of red roses is passion and true love, and the flower language of white roses is pure and innocent.

There were two people when they came, and three people when they went back. Zheng Chengyi also returned to the Sylàn Building of the Sha Tin Oriental Research Institute with Li Xuan. Today can be said to be the first practical application and debugging of AIPC-100 computer, and Zheng Chengyi specially came to the scene to have a look.

"After the AIPC-100 was launched. The follow-up development of various functional modules should also follow immediately!" Li Xuan said.

The AIPC-100 industrial computer has up to 6 external card slots, which can be configured with different external components to achieve various functions. For example, install a number of jù capture cards. It can strengthen the computer's data collection and analysis capabilities, so that the AIPC-100 computer can be more widely used in industrial testing, real room analysis and other fields.

Zheng Chengyi nodded, he is the general person in charge of the industrial control project. In addition to the completed AIPC-100 computer, the Oriental Research Institute is also developing products such as industrial control single-board computers, preparing to form a rich and completed product library for users to choose.

"The East-Unix operating system developed by Dongfang Software Company is still easy to use!" Li Xuan asked.

The AIPC-100 industrial computer does not use the East-DOS operating system like the previous ABC series computers, but adopts the new East-Unix operating system. Dongfang Electronics had already obtained the UNIX development license from the Bell Yàn room in 1980 to develop its own UNIX version of the operating system.

For ordinary people, the only computer operating system they usually come into contact with is the Windows series of Microsoft's Great Demon King. In the enterprise market, Windows Server has not been able to dominate the world as much as it has in the PC space, and its main competitor is UNIX.

The UNIX operating system was developed in the late sixties by two researchers in the Bell Yàn room, and gradually spread after being rewritten in C in 1973. At that time, the Bell Solid Room didn't take the operating system too seriously.

As a result, the source code of UNIX spread rapidly, and in 1979, when the Bell Sil Yàn Room began to realize its commercial value, it was impossible to gather it together for fine commercial development because the source code had long been scattered.

As a result, the Bell Shi yàn room simply broke the jar and broke it, and adopted the model of external authorization, and the research institute used it for free. A license fee is required for enterprise use. Li Xuan obtained the development authorization of the UNIX system from the Bell Shi Yàn room early.

His idea from the beginning was clear: the personal-level operating system would adopt East-DOS. Make the software as easy to use and feature-rich as possible. Enterprise-level products that require higher stability and security use the more concise and stable UNIX system.

UNIX from its birth to the gradual start of commercial use. There are almost 10 years of "raising in the depths of the boudoir". It was during this long period of time that the Bell Room and other scientific research institutions and universities continued to make argumentative revisions to the UNIX system.

By the time Unix is commercially developed, the system has been very complete, which is also the fundamental reason why Unix has firmly controlled the enterprise market with high requirements for stability and security for a long time. Naturally, it is impossible for other commercial software to spend such a long time looking for bugs, and it is inevitable that a lot of holes and patches will be left in the software.

For example, the later Microsoft Windows system has been sprayed since its birth, and there are as many loopholes as a sieve. It's not that Microsoft's developers are too technical, it's the entire Windows system. There are tens of millions of lines of code. Finding bugs is a huge undertaking, and Microsoft can't afford to spend years fixing them.

The east-dos system developed by Dongfang Software Company before also has a million lines of code, and Li Xuan is also unlikely to spend too much time looking for system vulnerabilities, but will choose to solve the vulnerabilities by adding patches when they are discovered.

"This east-unix set is pretty good, but the interface adoption seems to be biased towards ucb-unix?" asked Zheng Chengyi.

Li Xuan nodded and said, "East-Unix of Dongfang Software is developed by the American R&D center, and most of the members of the development team are masters recruited by the company from the University of Berkeley (UCB)!"

The Berkeley version of the Unix system, in addition to the official version of the Bell Yàn room. The most influential version. For this reason, the Bell Syàn room also sued the University of Berkeley on the pretext of infringement, trying to block this version through legal means.

"We at Berkeley are indeed Crouching Tiger, Hidden Dragon!" Zheng Chengyi said proudly.

Only then did Li Xuan remember that the alumnus in front of him was an alumnus of Berkeley University, and he was naturally full of pride when he talked about his alma mater.

The shortage of software development talent in Hong Kong is a very real dilemma. It was not easy to assemble an R&D team to develop the East-DOS system. UNIX is an existing system, which is not the same as developing a new system.

Developing East-DOS was like drawing on a blank sheet of paper, so you didn't have to worry too much. And develop a new version of UNIX. It's like dancing with shackles and requires a deep understanding of UNIX. Hong Kong does not have the talent to do so. After the continuous expansion of Dongfang Software's U.S. R&D center, the number of engineers has increased to more than that of the Hong Kong headquarters.

Responsible for the follow-up development of the East-DOS operating system and East-dbase library software. and the development of the new East-Unix operating system, while the Hong Kong headquarters is mainly responsible for the subsequent development of the Office series of office software.

Once the operating system forms a market monopoly, its importance is far from being comparable to other application software, and Li Xuan's division of labor with Dongfang Software Company can be regarded as a rainy day. It will give some people more peace of mind and reduce their excuses for future attacks on Oriental Software. And in Li Xuan's plan, Dongfang Software will go to NASDAQ to be listed in the future.

Compared with AIPC industrial computers, another user of the East-Unix system, the workstation computer of Aikang, is also under intense research and development. Another name for a workstation is a server, and it's more powerful than a regular personal computer.

The most famous workstation computer on the market today is the Apollo Computer Company, which uses the Motorola MC68000 processor.

The performance of ERM-1 developed by the Oriental Research Institute was a little rudimentary, so Li Xuan did not plan to use the ERM architecture to build a workstation computer, but set his sights on the MIPS architecture jointly developed by the Oriental Research Institute and Professor Hennessy of Stanford University.
