Magnetic tapes can also record video, just at specific points in time. It's perfectly normal for Japanese soldiers to watch some pornography on the train.
This time, instead of disassembling it, he picked up an older, non-GPS navigation system and powered it on for testing.
Let's study the functions first. After all, it's technology from eight or nine years ago. Let's see how others have become world leaders in the field of navigation.
As someone ahead of his time, Xing Baohua felt a little embarrassed that he couldn't figure out the Japanese navigation system in the lab. He tried to explain it, but most of it was beyond his understanding, so he called the foreign trade department and asked someone who spoke Japanese to come and translate it.
The instruction manual is quite thick and difficult to translate, but for the sake of the work and experimentation, it must be translated no matter how thick it is.
When Xing Baohua returned to the hardware team, he saw that some team members were disassembling a monitor. It was a five-inch CRT monitor, commonly known as a fluorescent screen monitor.
It can be viewed as a five-inch TV. Xing Baohua even said he was wondering why he would take it apart.
He stopped himself from speaking, because by disassembling the screen, he could see that there was something inside the transparent section.
After handling it myself, I picked it up and looked inside. I saw a semi-transparent piece of paper or plastic that had a slightly greenish sheen.
Xing Baohua guessed it was made of plastic, then shook his head, saying that once the machine was turned on, the temperature inside would be very high, and the plastic would shrink into a lump.
It's difficult to remove the contents from a pre-formed fluorescent screen; the only solution is to break it open. However, the lab has cutting equipment, which saves the trouble of breaking it open.
When Xing Baohua took out the contents, he was quite surprised and had to admire the technical team for managing to fit two inches of transparent glass inside the screen. On the glass, there were tiny lines and tiny characters.
Instantly, Xing Baohua understood that this was using internal projection technology to magnify the map on the fluorescent screen.
When Xing Baohua tested it with electricity, he thought it was a data map. This Japanese version can't be considered an electronic version; it should be classified as a mechanical version.
So how do we achieve location and movement?
Three days later, after integrating the research on the disassembled parts and the user manual, it became clear that this was not a purely electronic navigation system at all, but a mechanical navigation system. The only electronic component was the electronic gyroscope.
Honda's electronic gyroscope navigation device looks very complex and technologically advanced, which makes Xing Baohua admire its forward-thinking nature. However, once you understand how it works and its principles, it is incredibly simple.
Take that semi-transparent map, for example. When the car moves, it manually determines its current position by comparing a series of data input from the car and the instruments inside the system with its origin.
I've used several Z-axis and Y-axis adjustments to get the destination, but it's not precise; it only provides a general range. After the car is started and powered on, it adds a flashing dot.
Yes, this flashing dot represents your car.
Once this point is combined with the map overlay on the display, you can drive away.
The role of the electronic gyroscope in this navigation system is to stabilize the light spot on the fluorescent screen.
After all, the lines on the map represent roads. When there is a bump or a turn, the time point will drift and not be on that line, making it difficult for the driver to judge how they went from a good road to another road.
This is to prevent the light spots from moving around randomly on the map.
So what is the helium gas used for? The working principle is very simple: it is circulated in a helium cylinder using two wires.
When a car is driving straight, helium gas evenly impacts the two wires, keeping them at the same temperature. When the vehicle turns, the flow of helium deviates, creating a temperature difference between the two wires. The onboard computer detects this difference and translates it into directional information. This is what is marked on the map after a turn.
This non-GPS system, except for the electronic gyroscope, has some upgrade potential, making the entire system useless. In other words, Xing Baohua lost at least $700,000.
As for the new navigation, it is the same as the old version except for the core components, but the map mode has changed.
Instead of carving small maps on a piece of glass, they used magnetic tape to store the maps.
Fortunately, it wasn't a pornographic film. Xing Baohua was genuinely worried that it might turn into a two-person movie during the function testing. Thankfully, it was all electronic data.
To be honest, the new navigation system still has a bit of an electronic feel to it.
But it's still far behind. At least 1.4 million of the 1.5 million investment is wasted. The remaining amount is just the patent for the electronic gyroscope, which is only worth about 50,000 US dollars. Anyway, Xing Baohua can't use it here; he can only upgrade it.
Only then did Xing Baohua realize what non-GPS meant. Oh dear, isn't this just the offline version?
When Xing Baohua was working on maps in Hong Kong, he also used offline mode. Although the principles were different, the working conditions were the same.
The dots on the HK map are not generated by electronic gyroscopes and helium, but by base station signals, which are much more advanced than Honda's, but they are not as expensive as Honda's complete set!
The complete set of equipment costs over seven thousand US dollars on the market. How much does Xing Baohua sell it for, including the tablet?
That's true. Car accessories are incredibly expensive. Getting a navigation system or computer replaced at a 4S dealership can easily cost several thousand dollars, and sometimes even tens of thousands.
We'll sell this for 1.5 million to learn a lesson. Anyway, we've already bought the patent for the electronic gyroscope, so we'll develop based on that. Of course, we won't be using helium. Only the Japanese would dare to imagine this and use it in electronic products.
Indeed, the Japanese have put a lot of effort into the chemical industry. Take hydrogen energy, for example; they were the first in the world to develop and promote it.
Many experts say this product is great, but Xing Baohua knows it's a trap.
