The future society can be called 3A society. The so-called "3A" means factory automation, office automation and home automation.
Office work is inseparable from drafting manuscripts, delivering official documents, calculating data, analyzing charts and storing files. Dealing with these daily chores is often time-consuming and laborious, which is far from meeting the needs of collecting, analyzing and storing information quickly in the future society. Office automation is the use of computers to complete the above work.
In the future office, the staff will work in front of the computer terminal screen. Communications, credit and accounting are all done by computers. Writing, with a light pen, can "write" words and "draw" pictures on the screen, and can be modified at any time. It is very convenient to draft documents and design drawings with a light pen. Writing documents and materials, using a dictation typewriter, can directly convert people's speeches into words without typing. To collect and sort out materials and documents, you can use a "reading" machine, you can scan documents and photos optically, and store the "read" content digitally, which is very convenient for reference.
Office automation can not only improve work efficiency and reduce errors, but also bring about changes in office methods. Modern equipment makes it impossible for all employees to work in the same office building. Some workers can work at home or other places, as long as the computers they use are integrated into the overall computer office system. Therefore, the office location and working hours of the staff will be more flexible.
Although the computer into the office has many advantages, there are also some unsatisfactory places. In some computerized offices, people have been worried about their health. Because of working in front of the computer terminal screen for a long time every day, symptoms such as headache and decreased vision often bother the staff, and high tension can also lead to other diseases. Therefore, improving office conditions, such as lighting, ventilation and heating, has attracted more attention.
City square building
This is a building controlled and managed by an electronic computer. As soon as people enter the room, the windows will automatically open and the indoor light will automatically adjust, so no matter which seat you sit in, you will feel comfortable and soft. The temperature of the whole building can be adjusted to make the four seasons pleasant, so it is called intelligent building.
The intelligent building can be used as a teaching building or an office building with high degree of automation. If it is used as a classroom, the class time is closed and guests are not received; If it is an office building, the visitor only needs to enter the name of the company or department he wants to visit on a typewriter-like machine, and a soft voice will tell him which elevator to take and which floor to go to. When tourists enter the elevator, the elevator will start automatically. At this time, the display screen in the elevator is broadcasting today's weather forecast and important news at home and abroad. After a while, a soft voice will remind him what floor it is. When visitors came to the company reception room on this floor, it was still dark inside. Just as he pushed the door and walked in, the room suddenly lit up, and the air conditioner would blow hot air or cold air due to different seasons.
In intelligent buildings, optical cables made of optical glass fibers crisscross, forming a computer-centered communication network. The classroom or office is equipped with TV communication equipment for TV teaching or work contact. The TV here is bidirectional. Teachers can sit in the office and give lectures to all classes. Students can see the teacher on the TV screen, and the teacher can also see the students in each classroom and hear their questions, just like face-to-face teaching. In such an office building, the company manager can grasp the progress of each department without leaving the office; If necessary, you can also attend international conferences in the TV conference room. Staff use word processors, data processors and personal computers to handle daily business, which greatly improves office efficiency.
Intelligent office building is an electronic building, with the building as the "body" and computers and electronic equipment as the brain and nerves, forming a "flesh and blood" building. Whether students and staff are absent or late or leave early, electronic equipment will automatically check attendance; The salaries of teachers and staff will be paid automatically. More interestingly, intelligent buildings also use negative ions to adjust the surrounding environment. Trees are evergreen all the year round, birds are singing and flowers are fragrant, and buildings are bathed in sunshine, which makes people relaxed and happy.
Universe factory
There are already many factories on the earth, so why build factories in the universe? Because most factories on the earth use coal and oil as energy, the exhaust gas and waste discharged will seriously pollute the environment and pose a threat to human survival. The energy used in the space factory is solar energy, which has no pollution to the environment. Solar energy is inexhaustible cheap energy, so building a factory in the universe has high economic and social benefits.
On the other hand, space has conditions such as weightlessness, high vacuum, ultra-clean and extreme temperature. This special space environment is necessary for the production of some special items, and the earth cannot provide such a good production environment. For example, rockets need wear-resistant lead-aluminum alloy, but due to the gravity of the earth, when melting these two metals, lead always sinks to the bottom. After cooling, it is not a uniform alloy block, but a layered cake. It will be much more convenient to produce this alloy in the cosmic factory. Because everything loses weight there, the two metals will not delaminate because of their different specific gravity. According to statistics, about 400 kinds of alloys that cannot be made on the ground can be made in space factories.
Organisms and drugs can also be made in space factories. In space, some cells grow very fast and can be easily separated. 19921June14th, China conducted a biological experiment with recoverable satellites, and cultivated an anticancer organism-asparagus, which proved China's achievements in aerospace pharmacy.
Happily, the raw materials needed for space factory processing are not completely dependent on the earth, because the moon and many asteroids have almost all the raw materials needed for space processing.
It can be predicted that in the near future, the space shuttle will fly frequently in space, and the "rare treasures" and "panacea" produced by No.1 Aerospace Factory will be continuously sent to the world family for the benefit of mankind.
