Feng Shan's face became even redder. Although she could only partially understand the teacher's words, she also roughly understood the meaning. Moreover, she was also keenly aware of the other meaning in the teacher's last words, so she swallowed back the last question she wanted to ask - she had already got the answer.
Originally, she wanted to explain the connection and interactions between herself and her junior, but now that she thought about it, it was no longer necessary. The confusion and nervousness that I was feeling at first let go, and I suddenly felt that the world is so vast. She took a step back and bowed deeply:
"I have no problem! I'm going to sort out the household registration materials for the classification machine test again!"
The next day, Li Janai arrived at the workshop warehouse early, intending to find out the household registration information that his friend asked him to check yesterday. But when she saw stacks of neatly arranged household registration information forms, she was dumbfounded—in the past, these materials were arranged according to the name of the commune and the head of the household, and the cards of the whole family were all together. But now it has changed. It has been sorted according to place of origin and occupation. Next to each stack is carefully written information such as place of origin, occupation, number of people... and other information.
There are household registration information for more than 10,000 people in parts of Lingao and Qiongshan counties. Where can I find the household registration of Lin Guanghui's family in Calais Commune?
At this time, Feng Shan walked in sleepily, and Li Janai quickly asked: "Mr. Xiao Feng, why have the order of these forms... changed?"
"Oh, today we are going to test the prototype of the sorting machine. The teacher said that in addition to classifying the cards by household registration location and surname, they will also use two types of information: place of origin and occupation to classify the cards. Because the number of people in each commune and the number of people with each surname have been counted before. Okay, so yesterday he asked Qian Yuzhi to reorganize the household registration information and prepare it to verify today's classification results. Last night...yawn...I checked the number of sheets in each stack again...check Until midnight..."
"Ah, by the way, you want to check on that family today." Feng Shan thought about it.
"Yeah. That idiot Qian Yuzhi... didn't even say a word to me."
As she said that, Li Janai suddenly remembered that she had drunk a lot yesterday, took a nap when she got home, and then stayed in her room at night to sort out and record some of the information she heard during the day. She did not meet Qian Yuzhi in the next room. . When she woke up in the morning, she also found a thermos bottle and two potato cakes at the door, with a note Qian Yuzhi left for her last night sandwiched between them.
"What should we do?" Li Janai was a little anxious.
"..." Before Feng Shan had time to answer, she saw Feng Nuo walking in in a hurry.
"Good morning, teacher." The two said in unison.
Feng Nuo said casually, "Okay." Then he immediately said, "Have these materials been sorted out? Move to the outside quickly, the prototype of the sorting machine will be installed soon."
After saying that, he walked out again.
The two people looked at each other and had to start moving their household registration information out.
"Let's talk to the teacher during the test later and check it with a machine. There should be no problem." Feng Shan said quietly.
Several naturalized migrant workers were busy around the components on the ground. Feng Nuo and several senior members of the research team stood aside to give instructions and chat.
"I still think it should be designed as a turntable, with a large 10-grid turntable. There are several baskets on the turntable. When the sorting machine senses which hole, it will turn the turntable to the corresponding basket and throw the cards in." A veteran explain. "Now your design is equivalent to 10 card reading systems connected in series. Each system is connected to only one relay. The ones with perforations are pushed horizontally into the card pockets on the side, and the ones without perforations continue to go. In this way, each card reading unit only needs To check whether one of the 800 holes is perforated is too inefficient."
"I remember that the tabulation machine reads one card per second," someone else said.
"Well, it will take a little longer, maybe a few seconds. The card reading device this time uses a newly designed structure by Dr. Zhong, and it is estimated that it can be controlled within 1 second."
"That's still too slow. It takes 10 seconds to sort one card."
"Old Liang, you forgot again. I explained it to you last time. When the first card is transferred to the second set of card reading institutions, the second card can be transferred to the first set of card reading institutions. In fact, Still 1 second per card."
"Oh, oh, right."
"The speed is pretty good, still more than 3,000 pictures per hour."
"There's no need to look too fast. What if the relay still can't adapt." Sun Li glanced at Qian Yuzhi who was installing the relay.
"It's no problem this time. We have improved the design of the relay during this time." Feng Nuo said quickly.
"When will the new winding machine arrive? There are always some problems with current equipment winding 0.1mm wire." He asked Sun Li again.
"About another week." Sun Li replied.
The standard parts factory recently produced 0.1mm diameter copper wire, and the electronic equipment workshop immediately produced a batch of enameled wires based on it. The effect is still very good, the size of some control relays has been significantly reduced, and the response is more sensitive.
"What material is used for the digital wheel of the counter?" Dr. Zhong asked. Each card pocket of the sorting machine is equipped with a linked counter, which is not troublesome anyway. The principle is the same as that of the tabulation machine.
"High carbon steel," someone answered.
"The wheel used in the counter does not require very good materials. In the current design, this digital wheel has no mechanical contact with the upper and lower stages, only electrical contact. We can make it into a module that can be quickly replaced. If it breaks Just pull it out and replace it with a good one. This makes maintenance easier and saves expensive materials." Dr. Zhong began to promote his modular idea again.
"However, the pin is the heaviest-loaded part in the counter. It needs to frequently rub against the ratchet teeth and requires a material with higher hardness." He added.
"Well, I'll give it a try next time. But there was something wrong with the design last time. The Y-shaped fork left at the wrong angle, which would cause the ratchet to move back, so that the other pin could not meet the punching surface."
"Oh, it's no problem this time. I increased the distance between the pins to ensure a reliable 'unlocking' position. In addition, the angle of the ratchet punching surface has also been corrected."
…
"Old Feng, you still haven't designed multi-condition classification. Are you a bit conservative? Tabulating machines and classification machines can only perform statistics and classification on a certain column of the card."
"Who says there is no improvement? There is still improvement. It can support up to 10 condition classifications." Feng Nuo replied with a hint of pride.
"Huh? How did you do it? Didn't you see any corresponding structure?"
"Although each card reading system only has one card reading contact roller, it can only read one hole at a time. However, the position of this contact roller is adjustable and can be adjusted to align with different columns and rows respectively. I read each card A control relay is added upstream of the card feeding relay. There is a switch on it, which can be activated or not activated. In this way, it is equivalent to inverting the relay that controls the card feeding mechanism. I can choose to send out all punched cards, or There is an option to send all cards that are not punched.”
"Then, for the second set of card sending mechanisms, I will change to another hole to check, and then send out all the cards that do not meet the conditions. By analogy, in the end, what is left are the cards that meet multiple conditions at the same time that I want."
"Well... this is too simple. First of all, you can't solve the problem of 'or' condition, because you have already sent out all the cards that do not meet the condition in the first card bag, right? Between all the conditions The relationship is all 'and'; secondly, the card you want is picked out, but the order of the original card library is completely messed up, and it is actually sorted randomly." Dr. Zhong said with a frown.
However, although this method was very crude, everyone still found the idea quite interesting, and the discussion was very lively for a while.
After a while, the machine was installed and running normally after being powered on, and the workers left. The elders half discussed and half chatted for a while, and then gradually dispersed - the day had just begun, and everyone had a lot to do. In the end, only four people from the electronic equipment workshop were left.
"Let's start testing," Vonn said. "Bring the card over, first..."
"Teacher..." Li Janai raised her hand, and then she told her about looking for household registration information.
Feng Nuo became interested, and it would be good to give it a try with a specific example.
"What's the name of the head of the household?" he asked.
"Lin Guanghui. From Calais Commune."
"The Calais commune is 1001014——"
In the area code table formulated by the Ministry of People's Livelihood, it is similar to the old time and space, except that 7 digits are used to represent the area. The top 3 are at the "provincial" level, 100 is Hainan, 101 is Taiwan, 102 is Jeju Island... This is the current direct jurisdiction of the Senate. 110-199 are reserved for the mainland, 200-219 are reserved for North Korea, 220-249 are reserved for Japan, 250-269 are reserved for Indochina, and 270-299 are reserved for the Nanyang Islands. The remaining numbers have not yet been assigned. If the site becomes too large in the future, you can also add one person at the front to solve the problem.
After that, there are counties/districts below the provincial level. In Hainan, 10 is Lingao, 11 is Sanya Yulin, 12 is Sanya Tiandu, 13 is Qiongshan, 14 is Chengmai...and the last one is the commune, in Lingao , 11 is Bairen Commune, 12 is Bobu Commune, 13 is Nanbao Commune, 14 is Calais Commune...
Actually there are 10 more. The 6th to 7th digits of the household registration address represent the commune/village, but all county-affiliated communes are numbered starting from 11. And '10' means that this person is a member of the senator's family who has lived here for a long time: the senator himself, spouse, children, other family members, life secretary or servant, etc.
"This time we only have part of the household registration data of Lingao and Qiongshan, so the first card reading position excludes cards whose fifth digit is not 0, which distinguishes Lingao and Qiongshan, and the second card reading position excludes cards whose seventh digit is not 4. This singled out the Calais Commune," Von Noau explained.
"The head of the household is named Lin, and Lin's location code is——"
"3354." Li Janai quickly replied.
"Well, then use the 3rd to 6th card reading positions to select the card with the last name of the household head 3354. Use the 7th to 10th reading positions to filter the last character of the household head's name. Is it Hui?"
"Yes, the location code is 2752."
