My 1982

() In a office of the 16th floor of the loyalty research base, Li Zhongxin and the Jie Hongtu stand together, listening to the Lin Xueliang, which is studying the study of one-dimensional code equipment, pointing to the projection inside the projector. Explanation.

This team of Lin Xueliang is a representative person of the international students in computer technology. It is also one of the representative characters of international students studying in the United States.

Among the previous years, the students sponsored studying abroad have chosen faith companies after returning to China abroad. They grate on the money to study abroad, and the opportunities bring to them.

To put it bluntly, there are many reasons to work to the faith company. First, the treatment of religious researchers will be almost the best in China. No matter from the work environment or other aspects, it has exceeded other research institutions. .

Therefore, after the young people like Lin Dynasty came from overseas, they have entered the work of the faithful research base.

After these people came to the work of the faithful research base, they found that they were very good here, far more than other places, so they communicated with their classmates and those around them, more and more research The elite continues to join the faithful research base, which is also an important reason for the first two large-scale research bases after the first 20 high-rise buildings just build the first 20 high-rise buildings.

The four or five people under Lin Xueliang's hand are almost specializing in computer technology. They are also the elite talents in this area, and they are allocated to Lin Xueliang's one-dimensional code team.

Lin Xueliang did not think that they made this thing so soon.

Through Lin Xueliang's explanation, Li Zhongxin also understood some things about a word of one.

Bar code card! To put it bluntly, the barcode recorded by a set of rules, empty and its corresponding characters, and the common bar code symbols are printed by black strips and white air, when light is irradiated onto bar code symbols, black strips and white Empty has a strong contrast, so that the different reflectance of the light is used to read information.

One-dimensional code is often used, and the barcodes on the daily products outside the foreign product are one-dimensional code. Its information is small, and only one code can be stored, and the data in the computer network is in this code.

The bar code card is simple, and the ordinary bar code is required to print or copy, the cost is low, but its imaging equipment is relatively expensive.

Different from the magnetic card and IC cards, information in the barcode card cannot be rewritten, in addition, the security performance is poor, the standard is not unified, which limits its application.

The information loaded by the bar code is a number, a letter, these numbers, and the letter is sided by a standard encoded by a standard code.

This time, Lin Xueliang mainly studied is to read equipment, according to Lin Xueliang's statement, under normal circumstances, the price of a cheapest reading equipment is required to buy a few thousand yuan or even tens of thousands of yuan. The renminbi, and through their efforts to study the applicable equipment for Chinese, if the flowers produced, the cost is not more than 3,000 yuan.

As long as they have these impaired equipment to put into production, then the loyalty company's chain supermarkets and integrated malls, etc., will save a lot of overhead.

The most important point is that it will greatly improve the speed, so that the salesperson and the cashier are more relaxed.

Lin Xueliang is very clear. Their current reading equipment is actually a bar code scanner or a bar code reader, which is a device for reading the information included in the barcode.

The structure of the bar code scanner is usually the following sections: light source, receiving device, photoelectric conversion component, decoding circuit, computer interface.

The basic working principle of the scanner is that the light emitted by the light source is irradiated onto the bar code symbol. The light reflected is imaged on the photoelectric converter, and the codon is interpreted as a digital signal that the computer can directly accept.

The faith company now fully has the ability to start independent production, and now it is necessary to let the leaders of the faith company see the practical performance of this thing cannot meet the requirements.

Li Zhongxin passed Lin Xueliang's demonstration, soon there were countless people.

Others don't say, the scanks that Li Zhongxin asked by Li Zhongxin in the supermarket in this and the municipality of the market, nothing more than the latter market is much different than the latter market, and only recognition One-dimensional code, that is, the function of supermarkets or other barcodes, and there is no way to ratio at the same time.

But! Li Zhongxin knows that this is already a huge progress. If you do this well, you will have a lot of the two-dimensional code and the two-dimensional interpreter.

Li Zhongxin is clear, and a large supermarket is used to manually enter the number of each item. So the long dragon rushed in front of the supermarket's cashier station will bring you an irritated shopping experience.

It's a small saying that people will definitely reduce the purchase of items to the supermarket queue, and they can directly lead to a decline in consumption levels.

The most important thing is that this barcode scan code technology will not only be used in the supermarket in the future, but also in many industries, among which faithful companies should use this technology.

Li Zhongxin felt that this barcode scan industry technology will be widely used in many fields and industries, such as retail industries, manufacturing, logistics, medical, warehousing, and even security, and so on.

The foreground of bar code scanners will be inexhaustible, as this is fully in line with the pace of modern society, people need to use the shortest time to make the most convenient thing, will also be a general trend.

"Professor Lin, when can this barcode scanner be started?" Li Zhongxin gave a slightly, and then asked.

"This mass production will be very fast, the light source, receiving device, photoelectric conversion component, decoding circuit, computer interface! Only the receiving device and photoelectric conversion components need to be produced, and the beautiful shell is relatively simple. As long as it is the company wants to invest quickly, it will be fast, and it is possible to make a finished product for about one month.

Just put more money, if this is no problem, then you can make a product one month. "Lin Xiangliang first respectfully gave Li Zhongxin, and then looked at Li Zhongxin seriously said.
