The batteries used on Ding Chen's truck are the ones that Ye Tianlong removed from the maintenance truck, and in terms of performance, they are definitely much better than those batteries that Ding Chen pulled back from the mountain.This shows how much hope he has for this truck.But after sending the first wounded back to the apartment, he was in a hurry to pick up the rest, and it was too late to recharge, so he had to directly replace it with another set of old batteries.This is also the benefit of modified cars, there is no stereotype, you can change it as much as you want.If the truck's battery box is closed, he can't really fit it in with a different type of battery, now he just has to put the new battery in the compartment.It is for this reason that the assault car driven by Driver Hao and another person does not have this kind of treatment, and can only honestly wait for charging.The biggest difference between battery vehicles and fuel vehicles is here, no matter how good the performance of the battery is, fast charging technology is the main factor restricting the continuous use of electric vehicles.In addition to replacing the battery, another job that Ding Chen needs to do is to rewrite the FM decoding program of the radio station according to the encoding scheme given by Su Ying.There are so many bands of radio communication, and it is easy to be monitored, so some people later developed a frequency-hopping radio station and jumped back in several different frequency bands, so that theoretically, it became very difficult for the enemy to crack the monitoring.In particular, digital communication means can make the decomposed communication packets be transmitted in out of order, in this case, it is almost impossible to successfully monitor without getting the other party's frequency hopping feature code.Normally, frequency hopping codes are randomly solidified, but in order to use them flexibly, there are also people who carry plaintext feature codes with them and temporarily use radio special software to generate codes.This is the kind of thing that Su Ying took out now.To be honest, when Ding Chen told Su Ying that there was a long-wave radio station in his apartment, Su Ying's surprised look clearly confirmed what Driver Hao said.Obviously, in this day and age, long-wave radio is indeed a very feared item.After watching Su Ying call out the model of the radio station in the small restaurant, Ding Chen couldn't help but complain: "Since this kind of play is very uncommon, why can you and Driver Hao recognize it" Su Ying glanced at him, then turned her attention back to the radio, and said absentmindedly: "Let's talk about this matter later, I need to study how to modify its encoding instructions." ”"If you believe me."
Ding Chen said stupidly: "I can do this for you." ”So in Su Ying's stunned gaze, he returned to the power supply car and skillfully compiled the frequency hopping coded text she gave into a data file in the on-board computer, and then imported it into the radio station of the small restaurant.Radio F4415 can store 64 different frequency hopping codes and listen to 16 channels at the same time, which means that it can use 16 channels of frequency hopping communication at the same time in the most complex cases, which is why it is strictly controlled.But in fact, the simultaneous use of more than four channels of frequency hopping will already bring great trouble to reception and transmission, will seriously slow down the decoding speed, interfere with the synchronization rate, transmit a large amount of data and the communication signal is unstable, and even the front voice data will be decoded very later.So in the case of a low level of secrecy, no one will use more than four channels at the same time.The frequency-hopping encryption code used by Ding Chen in the apartment is that only four channels are used, so Carlo can listen to the radio under the condition of ensuring normal communicationIf Ding Chen uses all sixteen channels, then the radio station has no room to listen to the radio.Su Ying was smart enough to guess the source of this radio station when she saw it, but it seemed that she was not surprised that Ye Tianlong was running around with such a radio station, but was curious about Ding Chen's ability to skillfully use the on-board computer.Anyone who has ever used a computer knows that when human-computer interaction, many shortcut keys can be used to speed up the operation, which is also the difference between novices and veterans.Because under normal circumstances, in order to ensure the correctness of the operation, the operation procedure does not recommend the use of shortcut keys, which requires the operator to take the initiative to explore.Su Ying noticed that Ding Chen's operation method was not formal, so he obviously did not receive training to operate FF4415 normally, but his operation speed was very fast, and he may even exceed most formally trained operators, the reason for this phenomenon was that Ding Chen was very familiar with the operating system, so he could switch between various functional software very quickly.This is a very surprising place, if Ding Chen comes from a gathering area that has been abandoned, then this gathering area should at least have a machine similar to the on-board computer of the power supply car, and there must be electricity, and more importantly, the people in this place can allow Ding Chen to fiddle with the computer like a toy, so Ding Chen can develop so many informal but convenient operation methods.To be honest, with such conditions that it can still be abandoned, Su Ying feels that it is really not easy to do it to this point.Of course, I am more interested in Ding Chen's birthplace.It's just a pity that neither of them has time to ask about what interests them now.So when Ding Chen swiped the data packet for the radio station, she had to say sourly beside her: "It looks like I don't need to convince you to install the radio station." ”Ding Chen glanced at her, "Do you plan to install this kind of radio station too?"
"It's not so advanced." ”Su Ying said: "Of course, I guess if Ye Tianlong comes back and wants to take back this radio station, we may be able to transfer the same one." ”Ding Chen was stunned for a moment and asked, "Isn't this kind of radio station regulated?"
"You already knew that it was Driver Hao who told you" Su Ying said, and then she immediately made a judgment, "It was Driver Hao who told you, otherwise you wouldn't have placed it in such a conspicuous place." ”She looked at Ding Chen, shook her head and said, "I can only say that you are lucky, God will help you." ”Looking at Ding Chen's puzzled look, Su Ying shook her head, "I'll do the rest, you go pick up Cheng Bin and them, bring more water, many people are dehydrated." ”Su Ying seemed to be familiar with the operation of the radio station, and she was obviously much more proficient than Ding Chen when debugging the radio station.So Ding Chen left with a stomach full of doubts.The size of Cheng Bin's caravan was not as large as Ye Tianlong's, and Su Ying took some people with him when he transported the refugees back, further reducing the size of the caravan.Later, they lost some of their men in the battle, so there were not many people under Cheng Bin at this time, but they took the entire gathering area with them to transfer, even if some people were scattered on the road, the remaining number was close to a hundred.So Ding Chen ran twice in a row, and didn't pick everyone back until dark, and on the last trip, two assault trucks charged with 80% power were also dispatched, which almost used up all the power in the apartment.Considering that the sun has set and the solar panels are not working at night, don't expect the three cars to charge tonight.This made Ding Chen very uneasy, so he planned to go to the river to charge the water truck after the water consumption peak in the apartment at night.Because the apartment had a bunch of wounded and filled the second floor.So Dr.
Li and the caravan's accompanying doctors were very busy, and Ye Dai was also called out to help.But even so, people continue to die.Ding Chen picked people up and went to the second floor to help, and heard Dr.
Li complain: "Without medicine, you can't do anything." ”The caravan's doctor was also sweating profusely.The members of the caravan all have identification tags with information such as blood type and age, and they are a little better when they are treated.The people in the gathering area didn't know that there was such a thing as a blood type, and even if there was a blood transfusion on the spot, they had to be matched first, and the three of them were busy.Moreover, the caravan's medicines were lost, the apartment was not well stocked, and after a few surgeries, the stock was exhausted, and the two doctors could only stare at each other.Ding Chen frowned and said, "I'll go to the old city to have a look." ”Ye Tianlong left the wounded in the old city, and there should be some medicine.Ye Dai shook his head and said: "It's useless, Ye Tianlong couldn't have imagined that there would be so many wounded, it was impossible to bring so many medicines out, and the old city must be poorer." ”At this time, I suddenly heard Su Ying shouting downstairs: "Come out and light a fire with me." ”Ding Chen was stunned for a moment, and said in his heart that this woman was crazy What is wrong with him He poked his head out of the window, just in time to see Su Ying standing in front of the building and shouting: "Light a fire, there will be an airdrop in ten minutes, hurry up, don't look like a woman." ”Ding Chen and Ye Dai glanced at each other, and they both felt that there was something wrong with the woman downstairs, could she be a man againaa2705221,,; mobile phone reading,
