"This stinky boy!"

Li Er couldn't laugh or cry, such an important matter, Yang Qiao actually arranged for a craftsman, or a slave craftsman to be responsible for conveying, professor, really, really, I can't say.

"Holy Lord, you see?"

The Ministry of Industry Shangshu looked at Li Er cautiously on the side.

He has to be careful, there are so many things on this railway, is it true that the people he arranged are not responsible, so he can only be cautious.

"Well, okay, just according to that kid's request, put the project you don't think the imperial court needs to be responsible for, give it to auction, no matter what family, as long as the workshop is around Chang'an, yes, it's best, it's better to set up this workshop in the industrial zone demarcated by that kid."

This is a new industrial zone outside the new city, which is about to open, and this opening is quite simple, only roads, and there are no other conditions.

"Okay, Holy Lord, then, the minister will go and arrange it."

"Remember, this, don't do anything again, and what is there to teach the professor, just start from this city, just right, what the kid said, the railways in this city, there is no need for telephone poles for the time being, this electric pole directly uses the support rod of the compound road, and let me take a look, whether this signal is easy to use, or not good, but don't be that kid bragging."

Li Er, it's not that Yang Qiao is bragging, but he is knocking on the book of the Ministry of Works, this, what he can be responsible for, actually asked him to change the personnel again, you said, the person you change, if you have the ability, it will be successful, it seems that there is not even a thing of a half bottle dangling, you say, if you don't knock on who you beat, if it weren't for looking at you, you are still more capable, even you, I would have changed it a long time ago.

Actually, Li Er is knocking on the book of the Ministry of Work, why is Yang Qiao not knocking on Li Er, and some officials related to this, this professional thing, especially related to technology, naturally needs professional personnel to do it, but, Yang Qiao said it so dryly, is it useful, to use a witty saying, called, I tell you now, you are not impressed, only after a bloody lesson, this impression will be deep, but, some people, even if they die, will not recognize their mistakes, such people, Just don't educate it.

I don't know when, under the re-road in Chang'an City, there are rows of shelves, on the shelves are porcelain pots, and above, there are iron wires one by one, but, according to Yang Qiao, this is temporary, this, after all, it is a signal line, and there is a line reserved for future communication, and, here, it should be regarded as the signal command center of Datang, whether it is the signal of each station, as well as the reserved line, it is very important, when the time comes, if what multi-strand cable is manufactured, Yang Qiao is ready, Bury the cable in the ground, so that you are not afraid of any damage to the line.

Moreover, this kind of primitive communication has an advantage, that is, it requires manpower to transfer, as long as a few more centers are erected, once a certain line is destroyed, then, it can be transferred from another place.

In short, this idea is beautiful, and it depends on whether it can be realized, that is, Li Er's leadership ability.

"Boy, is this what you call the Signal Console?"

"Well, Holy Lord, as long as you press this button, this traffic signal will be officially activated."

"Traffic signals?"

Li Er heard a new term again.

"Well, yes, Shengshang, this is what I studied with General Qin, because this is a new thing, mainly to regulate people's walking traffic, especially now, with trains, horse-drawn trains, and four-wheeled carriages, as well as horses in the city, as well as the avoidance of pedestrians, pedestrians to trains, running carriages, and the signal system formed by standardized traffic rules, coupled with the unique traffic signal system on the railway, collectively referred to as traffic signals, and, in the city, it is a traffic signal that is mixed with all traffic."

"Well, no, why do pedestrians avoid trains and carriages, and why do they avoid pedestrians? What's the difference? ”

"It's different, naturally there is, Saint, you also understand, it's the pedestrian's avoidance of the train and the carriage, this, the train, the carriage are all inertia, that is to say, when you meet a pedestrian, it is not that you can stop when you stop, so, this, it is the pedestrian who needs to avoid, pay attention to the light signal, as well as the traffic before and after, and avoid pedestrians, mainly the knight avoids pedestrians, because, riding a horse alone, as long as it is not a startling horse, it is easy to pull the horse away, and, in the city, this horse cannot run at high speed, This is the avoidance of pedestrians. ”

Yang Qiao only gave Li Er a slight explanation.

"Shengshang, if you want to know more about the details, here is General Qin's post, which has explanations for each item, but this, the Shengshang can understand or not, because this rule needs to be approved by a specific department, and it does not need to go through the Shengshang."

"Don't need my approval?"

"This is just a trial, one is on this section of the road, and the other is on the railway, so the surface is still very small, if it succeeds, then another story."

"Well, well, just press it like that, what's going to happen?"

"Nothing will happen, it's just that the trial place will be lit up with red lights, and then, at each intersection, as well as the railway station, the lights will be changed in order, and there will be light and bell signal indications."

"Okay, let's start it, albeit on a trial basis."

As he spoke, Li Er pressed a red button in front of him.

This is also an emergency button, if there is an accident, or an accident or something, someone will press this button, so that almost all traffic will be interrupted, but it is also a temporary assumption, and the specific content will be slowly improved.

"Okay, it should be their business next, right?"

Li Er looked at some people on the side, he knew that these people had been trained for a long time, but he didn't know what the training was, but what was waiting in this place, naturally, was related to the so-called traffic signal.

"Well, yes, Shengshang, because it is a trial trial, so, there are more people, and this signal is also a little more complicated, and in the future, it will be slowly simplified, okay, you can take up your post now."

"Okay."

"Don't look at me, here, there is no need to ask for instructions, according to this kid, the place of work, the workers just need to do their jobs well."

Li Er waved his hand very generously, these people had already greeted him when he came in.

"Okay, the signalman is in place, the signal observer is in place, the signal commander is in place......"

As one by one, the men quickly began their movements.

"The signal comes from the No. 1 intersection, there are more pedestrians on the left and right, and there are fewer pedestrians before and after, then, yellow lights on the left and right, then turn green, and the red lights ...... before and after"

"Let's go, boy, follow me to the scene to have a look, it's much better than looking at these little lights here, so many lights, I'm dazzled."

This is the benefit of having electricity, in the room, you can command, and, along the way, as long as you arrange an inspector, for example, under this compound road in Chang'an City, as long as one, or two inspectors will become, and then, at each intersection, there will be a staff on duty, this, in fact, no matter what era, this important intersection is indispensable to people, and, in Yang Qiao's previous life, this personnel is used more.

However, because it is not automatic control, this intersection needs to have a feedback signal, so the personnel on duty at this intersection, in addition to holding the flag to command, will also press some specific signal buttons on the side of the control booth according to the situation.

"Holy Lord, you see, that's the role of traffic signals, this carriage, and pedestrians, all walk in order, or follow the signal, stop at the red light, go at the green light, and, at this time, people don't know, the officer on duty at the intersection is explaining on the side."

"Everyone, everyone, it's not me stopping you, what about you, in the future, you have to learn to look at the lights in front of you, you see, the lights in front of you are red now, just let you stop, let this go in the left and right directions first."

"Why let them go first, and not let us go?"

……

This mess, it seems, this explanation will have to be explained for a while.

"And the Holy One, look over there, yes, there is another accident, this kind of accident seems to happen often in the city."

In the distance, I saw a group of people surrounding the intersection on the other side, and some Wuhou were standing on the side talking something.
