"Your Majesty, wait for me, wait for me."
As soon as Qin Mu left the Jianjia Palace, he saw Yun Qiaoer holding up her skirt and running towards her while shouting.
Tsk tsk, this is the wild girl. Which concubine in the palace dares to jump and run like this? Yun Qiaoer trotted up to Qin Mu, panting, but looking at him with shining eyes: "Your Majesty, you want to Are you leaving the palace? Take me there. Take me there."
Qin Mu looked at the four maids following her. They were probably trained with Qiao'er. They were all calm and breathless, like martial arts masters who were hiding their secrets.
"Girl, why are you here to join in the fun?"
Yun Qiaoer looked at him naively and said nothing, but those eyes that could speak, looking forward and looking forward, made everything clear.
Qin Mu thought about it and turned right out of the Meridian Gate to go to the Internal Supervision and Research and Development Department. He said, "You can only watch, and you are not allowed to cause trouble."
"Yeah." Yun Qiaoer nodded happily.
As soon as Qin Mu turned around, she immediately pulled Han Zanzhou aside and asked in a low voice: "Eunuch Han, what was your name just now? What is your Majesty going to do now?"
Han Zan replied with a smile on his face: "Hui Xiang Concubine, the Internal Control Research and Development Department has just developed a telegraph machine. This slave is here to report the good news to Your Majesty."
"Telegraph? What is this? What is the use of this, Your Majesty?"
Han Zan explained the functions of the telegraph machine to Yun Qiaoer in detail on Monday. After hearing this, Yun Qiaoer happily chased after Qin Mu, like a little oriole, just in front and behind, and chirped: "Your Majesty, this time is fine, if you visit Xijing in the future, if you don't take me with you, I will send you a telegram every day, um, I want to ask if you have had breakfast, and then if you have lunch..."
Qin Mu gently flicked her forehead, laughed and said, "Do you still want to ask me if I have gone to the toilet?"
"whee... ... .."
Qin Mu came to the Internal Control Research and Development Department and didn't listen to anything. He first went to see the transmitter and receiver with his own eyes. He had never seen this thing before, so he imagined it to be more complicated;
When I saw the result, I couldn't help but want to laugh. It was nothing, just an iron rod and a circle of copper wire. Adding some bits and pieces, it's not worth much. Is this the legendary tallest ticker
As for the transmitter, not to mention, in fact, as long as you are smart, you don't need any transmitter at all in principle. Just connect and disconnect the power cord... and repeat this, and you can send the message.
"this one?"
"Your Majesty. Yes, this is the ticker. Weichen and others are improving the belt runner so that the runner can automatically rotate at a constant speed when the ticker is ticked. In addition, Weichen has thought about it, but this runner is still quite troublesome. If the conditions are not met, you can not use this wheel.
Just put an iron nail cap or something on this piece of iron. When sending a signal, the circuit is connected and current flows through the electromagnet. Generating a magnetic field will attract the iron sheets above. When the patch collides with the magnet, a "click" sound will be made.
Release the button, the current disappears, the iron piece bounces back, collides with the iron nail cap above, and makes another "snap" sound. As long as the telegraph is placed in a relatively quiet room, the "tick" and "tap" sound intervals between the two collisions of the iron plates can be used to distinguish long or short tones, thereby achieving the purpose of accurately sending and receiving telegrams. . "
Qin Mu listened and nodded frequently. He was still concerned about the transmission distance. He immediately said: "What is the longest transmission distance at present? What are the problems with the power provided by the existing batteries?"
Huang Sheng quickly put away his smile and replied cautiously: "Your Majesty, the R&D Department currently does not have much copper wire in stock, so it is too late to measure the distance. However, Weichen has tested repeatedly and the power consumption when sending the signal should not be large."
Qin Mu shook his head and said: "Although I don't understand it very well, I feel that this does not seem to be the same. Just because it consumes less power does not mean that its transmission distance must be far. Theoretically, the resistance of iron, copper and other metals should be the same different;
The longer the line, the greater the resistance produced. The greater the resistance, the smaller the magnetic force generated by the transmitter when the power is turned on, until the magnetic force cannot attract the iron sheet above. Come down. "
"Your Majesty is right."
Don't say anything, let the experiments speak for themselves. Qin Mu immediately said to Han Zanzhou: "Old Han, you will immediately allocate a sum of money to purchase copper wire and iron wire. You must experiment with both to see how effective they are in transferring?"
"Yes, Your Majesty."
Qin Mu watched Huang Sheng perform the process of sending a message on the spot again. He watched it with gusto, not to mention Yun Qiaoer, whose sharp eyes were staring at the small iron plate of the message receiver rising and falling;
Looking at her like that, she was probably already planning to make one for fun. After the telegram was sent, she turned to Qin Mu to see how he compared the telegrams.
Qin Mu was no longer as excited as when Han Zanzhou went to report the good news. After all, he had used the mobile phone before, and seeing how crude the transmitter was, he really didn't like it, so he could treat the matter calmly.
But Yun Qiaoer was different. The transmitter was not only simple, but the password comparison was also easy to understand at a glance. Qin Mu saw her eyes getting brighter and brighter. He patted the back of her head and said, "Girl, what are you thinking about?"
"Your Majesty, I also want to make a few of this transmitter, is that okay?"
"What are you doing?"
"Pretend it in the palace."
"Huh?" Qin Mu couldn't help but glare at her. This girl's idea was very strange. Could it be that she wanted to pull two wires from her bedroom to the dragon chair in the Jinluan Palace? If nothing happened, she would send a report and ask: Your Majesty, are you? There won’t be one next time? Your Majesty, are you in a hurry to urinate... Well, you were the only one who couldn't think of it anyway. "Nonsense!"
"Hehe... Your Majesty, it's fun, and it doesn't cost much. I can just use my own private money to do it."
Qin Mu laughed and let her go. If you don't let her play with it, I'm afraid she won't be able to sleep tonight.
Han Zanzhou's work efficiency was certainly not bad. Starting from the next day, he found a large amount of copper wires and iron wires and began to set up wires in front of the Army Academy outside;
There is no shortage of idle people in the city of Nanjing. A large number of nefarious people caught wind of the incident and came to watch. Some even rushed to help dig out wooden poles for burial in order to get "first-hand information."
Qin Mu also ordered Liu Meng to mobilize two thousand troops to help set up the wires. The wires were pulled over here and the wooden poles were buried there. The progress was rapid.
Huang Sheng went home last night, took a shower, put on a brand new official robe, and sat under a parasol in front of the Army Academy. There was a table in front of him, a transmitter on the table, and a battery next to it.
At first, he tried to send a report every five miles when the wire was set up. It was very good. There was no difference at five miles, ten miles, or fifteen miles, but he almost exhausted the horses that reported the news.
At the end of the day, the wires were stretched out for fifty or sixty miles, and the effect of sending and receiving reports was not affected at this distance. This made Huang Sheng more and more excited. He really wanted to set up the wires farther overnight.
In the Great Qin Palace, Yun Qiaoer only took half an hour to set up the wires from her bedroom to Qin Mu's Qianqing Palace.
She was having so much fun that Xiao Mingyue jumped up and down with her behind her, her face turned red, and she even forgot to feed her precious pet giant panda.
Momo Ruoruo and other palace maids in the palace were also vying to see what was going on, and it was very lively.
After setting up the wires, Yun Qiaoer made up a set of passwords, and then played with Momo Ruoruo by sending messages and guessing riddles, which was a great time.
Qin Mu was too lazy to care about her, so this girl just wanted to be fresh. Life in the harem was actually quite boring, so why not let them have some fun.
At dusk, he received a report from outside the palace that the wire rack had been out for sixty or seventy miles and had no impact. Qin Mu felt a lot more at ease. He suddenly remembered that he had seen a movie before and seemed to have seen an old-fashioned transmitter. What is practical is just a pair of large batteries as thick as an arm.
Today's large storage batteries have 120 volts of electricity, which means that even if they are thousands of miles apart, they may not be affected much. If this is the case, it will be of great help to control the Western Regions, Siberia and other places. So, Qin Mu is full of expectations
In the next ten days, the wires were stretched out for 800 miles and were still in normal use. This incident suddenly became a hot topic on the streets of Nanjing. However, people did not call it telegraph, and I don’t know who gave it a nickname, Qianli. Sound transmission.
