Chapter 1938 Punch Machine

Feng Nuo is currently reading a post on the BBS: "If there is another wormhole, will you go back?".

This is a menstrual post on the BBS, but in the past few years not only have fewer and fewer people have gone to the BBS, but the number of times on the BBS has also decreased, and the number of replies to this post has also decreased.Ten days and a half months can't produce a new reply.Of course, this is not unrelated to the overall cooling of BBS.The enthusiasm of the veterans for the BBS has dropped significantly, let alone upvoting posts, there are very few people who open posts.

The grand occasion in the past when a post of "senator's power" could build up thousands of floors is gone.Firstly, the elders are busy with affairs and have no time to gossip on the BBS, and secondly, everyone is becoming more and more famous and powerful, so it would be "lost of identity" to gossip on the BBS.As a result, proposals, memorandums, notifications... these official documents with various titles have replaced online discussions.

Because Feng Nuo manages the computer room and also serves as the BBS administrator, he has to go up to have a look from time to time.Maintain the database of the forum.Will also check to see if there are new posts under this post, but he never speaks on it.In fact, until a few months ago, he felt that his answer was "yes".But he will never say it out - other people's replies may be just gossip or venting dissatisfaction, and he must never show the slightest "wavering of the revolutionary will."

I stared at the BBS for a while, thinking about what answer I would give now.For the first time in the past few months, he felt his connection with the world. He connected in series, held meetings, checked information all night, and reviewed college textbooks that he had forgotten about [-]% or [-]%. Mouth, this is a sense of fullness that never existed in the old time and space.

"It turns out that this group of guys with red faces feel like this!"

A rumbling sound in his stomach interrupted his thoughts, and he turned his gaze to the materials on the table.With the deepening of the computer project, his desk became more and more messy, full of documents pouring in from all directions.

Fonno felt exhausted just going through them all—there were so many things to coordinate, and he now fully understood why the mentor was "not doing his job" all day long.

It's a pity that I don't have any graduate students to drive...

The first report was a trial report of the hole puncher.The punching machine has been in use for a few weeks, and is currently carrying out pilot census work in Lingao and Qiongshan, where the grassroots conditions are relatively good.

Of course, the results of the census cannot just be stored on the punched card, which is not sure whether it is reliable.The census results of each street or commune are unified and "punched".Although the material strength of the punching machine is insufficient, the damage rate is high, the quality of the cards is poor, and the training time of the naturalized civilian staff is short, the rate of discarded cards in practice was once more than half, but the entire census work has been basically completed.In order to cooperate with the follow-up tabulation machine development work, the "resident population registration form" and statistical results of several streets were transferred to facilitate proofreading and verification.All the materials were moved from the Ministry of People's Livelihood and temporarily piled up in a warehouse of the General Machinery Factory.

The card feeding and transmission system of the card has been developed now. Under the condition of manual control in the laboratory, the current card feeding and the traditional system have been able to read cards one by one, send them to the processing unit at a uniform speed, stop accepting processing, and send out processing. After the card and a series of processes.Only limited by the quality of the card, the transmission speed is still very slow, and occasionally there will be paper jams and other phenomena.This system is the public basic system for the development of subsequent tabulation machines, sorting machines, and duplicating machines.The so-called sorting machine is to drive different card sending mechanisms to send cards to different card pockets according to the punching information read in multiple processing units connected in series.The so-called copying machine is two sets of transmission-processing systems, one of which is responsible for reading the punching information of punched cards, and the other set of processing units is used to punch holes in the same positions for new cards.The tabulating machine/accounting machine performs basic statistics after the processing unit reads the card and relies on programmable wiring holes and even control cards to perform digital-character conversion operations.

This part has little to do with the power source, but more about the design and development of the mechanical structure. If the electric method is used, the transmission will be more stable and the card feeding accuracy will be higher.Of course, electricity is also a prerequisite for automatic control by relays based on punched cards. The design of an electromechanical control system is much simpler than that of a purely mechanical control system. Feng Nuo was reluctant to ask others to help.

The next step of the research team is the development of the tabulation machine. The tabulation machine is roughly divided into two functions, one is data statistics and calculation, and the other is the output structure.Needless to say, data statistics and calculations, the word "calculation" of mechanical computers falls on it, and it is a subject that must be won; the output structure involves another big project, the Chinese typewriter system.The mechanical port once imitated a Chinese typewriter, and the result was limited better than the hand-cranked computer project, and it was basically usable.Moreover, because they could not solve the problems of typing efficiency and memorizing tables, Chinese typewriters in the old time and space were not popular. Except for necessary official documents and printed materials such as books and newspapers, they were not more convenient than handwritten mimeographs in ordinary occasions, and they were far from being compared with English typewriters.

However, the automatic typewriter system is still very attractive. Not only does it save the difficulty of manually memorizing word tables, but if the automatic control system passes the test, the efficiency of picking up characters will also be greatly improved.Feng Nuo even took advantage of the vacancy of the management computing center to re-optimize the arrangement of the character list in the dial.The Chinese coding scheme adopted some time ago is the area code arranged according to the pinyin, and the type arrangement of the Chinese typewriter is mainly classified according to the radicals, which are arranged for the convenience of people's memory.However, automatic typewriters do not have this necessity, as long as the type is arranged with the goal of "minimizing the expected average moving distance of the fuselage in the quotation process".Therefore, Feng Nuo calculated the transition probability between commonly used words based on the massive corpus extracted from the data center, and built a huge Markov model. After two or three months of solving in the computing center, he came up with An optimized dial scheme, Feng Nuo estimates that this scheme is 30% to 50% more efficient than the dial used in the old time and space. Of course, it is completely impossible to pick up characters manually.

Feng Nuo excitedly took the plan to the Chinese typewriter project team to sell his idea and asked for cooperation, but the fire was quickly poured out by a pot of cold water. At present or in the foreseeable future, they have no intention of electrifying or automating Chinese typewriters. These people generously introduced a lot of relevant materials and experiences to him, and showed him the models and prototypes.However, Feng Nuo's plan must rely on the complex wiring structure to convert the location code into dial coordinates, and then calculate the moving distance of the fuselage based on the current coordinates, and drive the motor accurately to achieve the goal. Although Feng Nuo does not understand electromechanical, he also knows this The position of the thing on the technology tree cannot be achieved within a few years.

After this setback, the research team organized several discussions on the Chinese output agency, and finally decided that it was too difficult, so they decided to postpone the development and focus on the function of card information statistics.At most, simply implement an automatic digital printing function as an output mechanism.

The statistical function of the card can be divided into two schemes. One is to make several accumulators based on the advantages of the electromagnetic storage mechanism over the purely mechanical storage mechanism; the other is to use the mechanical storage mechanism of the hand computer, and the relay is only used for automatic control.More complicated calculations are completed through the combination of multiple sorting machines/accounting machines.

Of course, Feng Nuo is inclined towards the first solution, and it is difficult to ignore the advantages of simpler implementation of mechanical storage at this stage.However, no matter which solution is used, the electromagnetic control system cannot be bypassed.The veterans of the research team have their own problems. Although Faraday and others are more suitable for the development of relays than themselves professionally, it is okay for a few people to hold a meeting to come up with ideas, but there is no time for the main research. The veterans of the power port Right now, I'm focusing on building generators, motors and other high-power systems, and relays aren't on the schedule yet.If Feng Nuo wanted to quickly advance this project, he had to tackle this technical difficulty by himself.

There was a stiff knock on the office door.

"Come in."

At this moment, Feng Nuo noticed that Feng Shan came in, with dark circles around her eyes, and asked, "An extra class in the morning?"

He remembered that Fangcaodi had no classes scheduled this morning.

"Temporarily added courses." Feng Shan said.

This kind of thing is very common, and the class schedule of Fangcaodi belongs to the type of the four major firms.But Feng Nuo felt a little doubt in his heart, he felt that Feng Shan seemed to be hiding something.The thought passed in a flash.Because he suddenly noticed that his maid was wearing the uniform issued by the general office for the secretary of life, commonly known as "maid uniform". Because of her part-time teaching in Fangcao, Feng Shan hardly wore "maid uniform".How did you come up with the idea of ​​wearing this today?

Unlike many maids who like to wear this uniform to show off their "different" status, Feng Shan does not like to wear a maid uniform, and even has some resistance.Feng Nuo generally doesn't force her to wear whatever she likes, and he's not a maid.

The reason should not be that there are too many dirty clothes that have not been washed and changed-the service agency has laundry service, Feng Nuo is very considerate of Feng Shan's busyness and hard work, and many clumsy jobs are outsourced to the service agency.

But he didn't have the time to delve into it: "I need to clean up the sanitation at home. I'm very busy recently, so I can't take care of it at all."
