Lin Zhiyue rubbed his sore eyes, forced himself to stay awake, and without taking a rest, plunged into the next stage of work without stopping.
She knew very well that the research and development of the navigation system had reached a critical point and any slackness could lead to failure.
She first placed the satellite signal receiving module, signal processing chip, display screen and other components on the workbench in order, and like a carefully planned chess player, she repeatedly deduced the best connection plan in her mind.
Then, she picked up the thin wire and started making connections with her solid knowledge of circuits and rich practical experience.
The direction of each wire has been carefully considered. She must ensure the stability of the line connection while avoiding signal interference caused by cluttered lines.
During the connection process, she was fully focused, her eyes fixed on the operating part, and her slender fingers flexibly moved between the various components, accurately soldering the wires to the corresponding interfaces. Every soldering point was round and full, perfect.
After completing the hardware connection, Lin Zhiyue immediately sat down in front of the computer and began to write the control program.
This is an extremely complex and brain-burning task that requires converting the various functions of the navigation system into precise code instructions.
She opened the programming software, and the screen was instantly filled with dense codes.
Her fingers tapped quickly on the keyboard, and her mind was like a high-speed machine, constantly conceiving, writing, and debugging.
During the writing process, she encountered many difficulties, such as how to optimize the algorithm to improve navigation accuracy, and how to achieve compatibility of the system with different car models.
But she did not back down and revised the code again and again.
Every time she solved a problem, she was one step closer to success, and the determination in her eyes grew stronger.
With constant modification and debugging, the program code gradually took shape, and Lin Zhiyue conducted the first system integration with great anticipation.
When she pressed the run button, the components of the entire navigation system began to work together, and data and instructions flashed across the screen. However, reality dealt her a heavy blow.
System error messages kept popping up, and the map positioning data on the display screen jumped wildly with no regularity at all, which was very different from the expected accurate navigation picture.
Lin Zhiyue took a deep breath and forced herself to calm down. She knew that panicking at the moment would be useless.
She quickly switched to debugging mode, carefully checking each code module and the hardware connection lines line by line.
As the investigation deepened, she found that some program codes had logical conflicts when interacting with hardware, resulting in chaotic signal transmission.
In order to solve this problem, she reorganized the operating logic of the entire system and carried out large-scale refactoring of the code.
This meant she had to overturn some of the code she had previously written and rethink and write more complex algorithms.
In the process of refactoring the code, Lin Zhiyue encountered unprecedented challenges.
The optimization of some algorithms requires a solid mathematical foundation and a deep understanding of navigation principles.
After working hard for several days and nights, she finally completed the code reconstruction.
When the system was debugged again, the map positioning data no longer jumped wildly and basically stabilized, but there were still some slight deviations.
Lin Zhiyue was not deterred by this small problem. She focused on the compatibility between the satellite signal receiving module and the program.
She carefully studied the transmission protocol of satellite signals and adjusted the signal analysis algorithm in the program to enable the system to more accurately identify and process satellite signals.
After countless parameter adjustments and tests, the accuracy of the navigation system finally reached the expected standard.
However, Lin Zhiyue was not satisfied with this. She thought of the differences in electronic systems and hardware layouts among different models of cars. In order to achieve the wide applicability of the navigation system, she began a lengthy compatibility test.
She installed and debugged cars one by one on various makes and models.
During the test, she found that the power supply voltage of some models was unstable, which would affect the normal operation of the navigation system;
Some car models have complex internal electromagnetic environments, which seriously interfere with satellite signals.
To address these problems, Lin Zhiyue designed a series of hardware protection circuits and software anti-interference algorithms.
After unremitting efforts, Lin Zhiyue finally created a navigation system with complete functions, high accuracy and strong compatibility.
When she installed this navigation system, which embodied countless efforts, on an ordinary car, started the vehicle, and the navigation screen clearly displayed the vehicle's location and surrounding map, accurately guiding the direction forward, tears of excitement flashed in her eyes.
At this moment, all the fatigue and hardship turned into the joy of success. She knew that she had not only created a technological miracle, but also brought about tremendous changes in the mode of travel in this era.
Lin Zhiyue drove the car that he had put so much effort into and parked it steadily downstairs of Director Song's office.
After she got off the car, she walked briskly and confidently towards the factory director's office.
As soon as he entered the office, Lin Zhiyue's face was filled with a proud smile, and he said, "Director Song, I have modified the car! Why don't you go down and try it? This time I put a lot of effort into it. Not only did I modify the engine and increase the speed a lot, I also added a super cool thing - a navigation system."
When Director Song heard the word "navigation system", he looked puzzled and asked, "What is a navigation system?"
Lin Zhiyue patiently explained: "Director Song, to put it simply, this navigation system is like having a live map with you at all times.
In the past, when we drove to unfamiliar places, we had to rely on paper maps and look at them to find the way, which was very troublesome and easy to get lost.
But with this navigation system, it's different! It can receive satellite signals to determine the location of our car in real time, and then plan the best route according to the destination you set.
Along the way, it will give you voice prompts about when to turn and how far you are to arrive, just like having a professional guide by your side to show you the way.
From now on, whether you are on a long-distance business trip or visiting an unfamiliar place in the city, you don’t have to worry about getting lost. It is convenient and efficient! ”
Director Song listened to Lin Zhiyue's description with surprise and curiosity in his eyes. He stood up and said impatiently, "Is it really that magical? We must see it for ourselves!"
Having said that, he and Lin Zhiyue quickly walked downstairs and came to the modified car.
Lin Zhiyue opened the car door skillfully and invited Director Song to get in.
Director Song sat in the driver's seat and looked around at the newly installed navigation device in the car. The small screen and simple operating interface made him wonder: could this small thing really be so useful?
Lin Zhiyue saw Director Song's doubts. She sat in the passenger seat and patiently explained, "Director Song, look here. This is the navigation switch."
As she spoke, she lightly pressed the switch, and the screen lit up instantly, showing a clear map interface and accurately locating their current location. "Now, let's set a destination and go to our partner in the next city."
Lin Zhiyue continued speaking as he operated.
