Found a portable radio in Baotou, and the use of the radio in the railway command, is Baotou to Mihai a huge surprise, I thought it would be very difficult, maybe in a series of stumbles, in order to gradually absorb the experience of Baotou, reduce the time difference between each train, the emergence of radio, give him great hope, can be directly connected with the train things have been made, but also can be so small, although the basic concept is difficult to understand, can not leave the distance of 25 kilometers, However, along the railway, it is the place where the most base stations are arranged and the most dense, at least, it can be easily used along the railway.

The first batch of real yàn, officially carried out, 12 trains equipped with radios, set off in turn, at the beginning, because conservative, or kept at about 40 minutes, under the command of dispatching, gradually shortening the safety distance, Mihai's subordinates, basically, are all dispatching talents, very familiar with the scheduling of trains, but the radio command is still a preliminary contact, Rao is so, the radio also showed excellent performance.

After the use of the radio, in the position is not in place, with the help of skilled drivers, plus some special arrangements, barely to achieve the accuracy of about 3-4 kilometers of the position to determine, the dispatcher in the gradual attempt, even the shortest limit reached less than 8 minutes interval, and finally determined the best interval, Baotou's departure interval, immediately improved, from the original every 40 minutes, reduced to 28 minutes a shift, and he expected a slight gap, but already very good. In this way, the carrying capacity of the entire Baotou railway transportation has been greatly increased, at least more than 4 times, and the total transportation volume has reached a huge number of tens of millions of tons, which can basically give full play to most of the capacity of the heavy rail railway, and is close to the average interval level of the United States.

In backward China, where there are not a large number of signal lights and all kinds of skilled train drivers, who can reach the average level of the United States, radio has played a huge role in it, and radio has brought great benefits, but it has also brought a huge problem, the problem of the practical use of radio. This problem also arose that Mihai had not considered at all, because in order to ensure the timeliness of radio transmission, the number jù is always reported, and the distance and calculation results converted into the number jù require a lot of calculations. In order to complete it faster, to reach the theoretical limit of 20 minutes, or even shorter, or even 8 minutes, the calculation speed must be fast and accurate, which is very important for railway scheduling.

New problems, bring new thinking, after all, Mihai is an expert in this area, even if it is a new problem, but also based on experience, a preliminary estimate, according to his estimates, can be achieved in the shortest time, if the result is obtained, without affecting the overall scheduling, the entire operating range, will be reduced by half, this is in the original 28 minutes, halved, 14 minutes interval, in the current world, the previous 8-minute limit, is a small probability problem, in the United States even the shortest reached three minutesBut that's extremely dangerous, what the railway needs is a steady dìng and an effective interval, 14 minutes is a god-like number, a railway, can be used as 2, or even 3 railways, such an efficiency, a single achievement, is crazy.

Mihai made a slight calculation, and finally formed a report and handed it to Yang Yuanzhao, the requirements of the whole report are very simple, it is a report invited by personnel, this time, it is not a railway professional, it is a large number of calculators, not any mathematicians or mathematics professors, but people who have received a certain amount of mathematics education, at least to reach the junior high school education in the United States.

This is very easy to achieve, with the Western-style education that China has developed for so many years, there are at least hundreds of thousands of people who meet this requirement nationwide, and even Baotou has been able to cultivate thousands of such qualified talents in the past year or two.

There is no other reason, Mihai needs too much, the number of 20,000 people, so that Yang Yuanzhao was stunned, although such a number, Baotou can make up a little, but this is not the solution to the problem, just 1500 kilometers, a total of three 4500 kilometers of railway lines, it takes 20,000 people, in the future, when Baotou's railway, up to 30,000 kilometers, 100,000 kilometers, or even more, this personnel requirement will increase to what kind of Cheng dù, Yang Yuanzhao can't think about it, This will not solve the problem at all.

Mihai looked at Yang Yuanzhao and frowned, and asked with some puzzlement: "Chairman Yang, is there any difficulty, there are not so many people in China, this is troublesome, and you have to recruit from the United States?" ”

"It's so difficult that it's just that such personnel, how to arrange, what to do in the future, continue to increase manpower?" Yang Yuanzhao couldn't take care of it anymore, and pointed out the problem to the point.

Mihai was stunned, he really didn't think so deeply, he just according to the current situation of 20,000 people, with such 20,000 people, he can easily increase the interval between train departures, from the current 28 minutes to 14 minutes, or even within the journey, which is a big increase for Baotou's railway capacity.

Yang Yuanzhao's reminder was very timely, almost instantly, the experienced Mihai thought of the current situation faced by Baotou, yes, the Baotou railway is encountering problems, which are a combination of several problems, the rapid construction of the railway, and the increasing freight pressure in Baotou, as well as the problem of normal play of the role of the railway, these problems are combined.

In Mihai's view, the genius idea of road construction machinery makes Mihai believe that Baotou has a strong ability to build railways, if it is not for the government's consideration, Baotou goes all out to build, 20,000 a year, or even 40,000, it may not be impossible, you know, Baotou is doing everything is 3 together, so 40,000 kilometers of railway, but more than 13,000 kilometers, at most Baotou and several surrounding provinces, connected together.

There are more railways, more scheduling, the difficulty of calculation will rise geometrically, not to mention the construction speed of 40,000 kilometers, the construction speed of 10,000 kilometers, in less than 5 years, it will make the increase in personnel incomprehensible, more than 500,000 people calculate countless numbers jù, to schedule the railway, which is a big problem for any calculation, the error rate, the difficulty of scheduling, including some basic management, which will make him completely big.

Mihai's face suddenly turned pale, this road is destined to be impassable, do you want to give up, at most, use radio command and determination, as a special job, but in this way, there is really a waste of radio function, what should I do, do I want to give up?

Looking at Mihai's embarrassed appearance, Yang Yuanzhao felt the same way, the calculation before the computer was almost devastating, the railway in Baotou was in the ascendant, the operation of this railway, the busy course, and the future generations could not be compared, Yang Yuanzhao could not and could not eat a fat man, and directly copied the busy course of the railway in the later generations, but it was not difficult to solve this problem, he hesitated for a moment, and asked: "Is the computer useful?" ”

"Computers? What is a punch card computer? Mihai thought for a moment, then said.

In this era, there is no computer, to be exact, there is no electronic computer, the West generally uses the traditional mechanical computer, which is on the basis of gears, and the mechanical computer is researched, the blue giant IBM is relying on this, undertook the task of the American census, and it took only 6 weeks to complete the census that took more than 10 years to complete, which also made the computer appear in the field of vision of most people, and the Pacific Railroad also has a computer, but it is less used. Because this kind of thing is more expensive.

"Does Chairman Yang have the channel to get a large number of punch card computers, if he can get 100 units, basically the total mileage of the railway is within 60,000 kilometers, there is no need to worry about scheduling, I am confident that the running section of the train will be reduced to less than 15 minutes!" Mihai said in surprise.

Punch card computer, this Yang Yuanzhao has never considered it, but Harpy as a technical reserve to consult, the United States is very dead, basically want to import, it is impossible, unless there is some technical and military exchange, the price of each unit is as high as 300,000 US dollars, this is 300,000 US dollars at the beginning of the 20th century, if you want 100 units, it is 30 million, isn't this another steel plant, Yang Yuanzhao of course will not put the money here, he pondered for a while, and asked: " Can you tell me what formula is needed to calculate these numbers, maybe I can help. ”

"That's it!" Mihai couldn't think of what Yang Yuanzhao was going to do, the train schedule, if you want to implement it perfectly, in addition to real-time monitoring, flexible scheduling, it requires a lot of calculations, it is impossible for everyone to be proficient in mathematics, any decimal point error, will make the operation a disaster, there are countermeasures, real-time monitoring, you can find problems early, perfect radio, you can communicate with the train, real-time guidance, which is already a level higher than the scheduling of the Pacific Railway, The flying order that is still stored in the station to transmit information, without this fast, radio is really a good thing, if there is a way to solve the problem of calculation, maybe this will not have to be canceled.

Mihai wrote down a few formulas almost without hesitation, Yang Yuanzhao took them and looked at them, they were all simple mathematical formulas, not very complicated, and could be completed with only a traditional function calculator, he had a bottom in his heart, and said: "Okay, leave it to me, at most tomorrow, I will bring something over, can you see if it works!" ”

After Yang Yuanzhao finished speaking, he left, leaving a confused Mihai, but there was still a glimmer of hope in his heart, perhaps, President Yang could really solve it. R1152
