Help all mankind

"Professor Ridoff said that this is a temporary emergency solution and does not guarantee a success. The final plan is still under development.

So don’t expect too much from today’s test results. Failure is common for engineers."

After arriving at the company the next day, Guigui, who was very unconfident, poured cold water on everyone to avoid making a fool of himself.

At the same time, it is also a step down for himself and Cliff.

Looking at the handmade wooden box in front of the table, Guigui couldn't imagine that this thing could solve their current problem.

There are two samples sent by post. One has been taken apart and placed on the table for everyone to analyze the working principle.

After dismantling this mysterious wooden box yesterday, Liang Shicheng studied for several hours, but still no progress, so he had to look forward to the actual test session the next day.

Open the box, the structure of the entire device is at a glance. The main body is an old-fashioned hand-painted circuit board, which is full of electronic components, but they look very old, just some of the most basic three-pin transistors.

The circuit board does not contain any integrated circuit chips, except that there are only some resistors, transformers and other devices. In short, the circuit composition is very simple.

Judging from the solder joints, there are obvious manual traces, like a hurried work.

Probably to prevent the originals from detaching due to virtual soldering, these large transistors were also marked with white glue and stuck to the motherboard full of temporary flying wires.

Except for the circuit part, there is only a convex lens left in the box, and some gears appear to be used to store data.

According to Liang Shicheng's statistics, the number of transistors on the entire motherboard is less than 50, and even the most basic adder functions in modern computer integrated circuits are impossible to achieve.

Although the overall physical structure is very simple, to find out how it works, Liang Shicheng has become a heavenly book.

The idea of ​​this thing can not be found in the knowledge he has learned. Although the knowledge of the university's analog circuit course can still be remembered, the device in this box is so simple that it cannot be used to process digital signals, let alone programming.

Although things are crude, Liang Shicheng has a sense of awe for it.

Now the wooden box was opened and placed in front of everyone.

"What else can this pile of resistance wires be used for besides heating?" a colleague half mocked.

Although Guigui is not a specialized science and engineering department, she knows a little bit about these things. When she was a child, she had disassembled Digimon A simple function.

But the wooden box is too straightforward. There is not even a chip. In Guigui's impression, this circuit should be used for warm water bags.

Guigui couldn't believe it. This was a device that Ridolf made with care to solve the problem. She suspected that Ridolf had sent the wrong thing.

But in fact, Ridov did not pay too much attention to it. After reading the folder provided by Liang Shicheng, he spent a few minutes carefully studying the issue, and then he made a comment.

"What does this question have to do with artificial intelligence? Do people nowadays like to mention artificial intelligence so casually?"

Then I entered a place where old parts were piled up, took out the needed parts one by one from the box, and soldered them on two circuit boards that I didn't know where to remove them.

Then I put the things on a counter and went to work on other things.

Looking back at the company, another colleague who has some insights sighed,

"The computer that uses gears to store data should be some years old. I hope it will work without delay."

Liang Shicheng picked up another wooden box and walked to the garage with a few people to start the experiment.

The wooden box has only three exposed parts from the outside. A large hole may be a camera, an indicator light, and an open-air AA battery.

But thinking back to the structure inside, the possibility that the big hole is a camera is extremely low.

The working method of the box is very simple, and it is explained with a few icons engraved on the box. The big hole needs to be checked and aligned with the driving direction of the car. After the battery is connected, when the indicator light is on, it means that the device has recognized that it has encountered The big truck should slow down.

Everyone made preparations as required, and then manually drove an experimental vehicle on the road. In order to find a large truck, Liang Shicheng ordered to find a toll station nearby and enter the highway.

At the same time he made a phone call to a stranger.

The experimental vehicle drove a certain distance and finally saw the first big truck. At first, the wooden box did not respond. Liang Shicheng continued to order to narrow the distance to the big truck.

This time, the indicator light turned on quietly, and when everyone saw it, they let go of their doubts and began to study the device with peace of mind.

After some groping by the driver, he found that he does not need to be very close to the truck. As long as the direction of the body is facing the truck, the indicator light will naturally light up. In other words, it will only collide if you continue to step on the accelerator. Circumstance, the alarm will be triggered.

Otherwise, in other cases, the wooden box is very honest, allowing big trucks to pass by.

At this moment, after looking at the rearview mirror and answering a phone call, Liang Shicheng warned that the good show started. First, let the driver deliberately slow down and let a special truck behind him overtake.

This truck was hired by Liang Shicheng with money in the morning and has been on standby. Its body is also painted with a special pattern.

It was another camouflage camouflage obtained from Professor Frank, but at the same time there were a few large lines written on the back of the box.

"A compatriot got close by mistake."

Liang Shicheng explained the situation a little bit, and then asked the driver to be more careful, and pointed the direction of the body toward the truck.

Faced with this situation, the wooden box kept the warning light on all the way.

By the time the experiment came to this point, it has been proved that the performance of Ridov's sample was very successful. After all, this is just a sample. It doesn't matter if it is simple, the important thing is the working principle.

For the sake of safety, the whole test process did not use unmanned driving, but it is enough to show the reliability of the wooden box.

Next, after the hardware team has figured out its principle, it is reduced and simplified, and then manufactured using modern technology, and the circuit of the warning light is connected to the driverless system, and then the program can be slightly modified.

Although Ridoff’s solution does not help the unmanned driving system to evade in front of the truck, as long as the program is set to brake immediately once the warning light circuit is turned on, safety accidents can also be avoided.

After all, it is extremely rare for a large truck to hide in front of an unmanned driving system.

Liang Shicheng sat in the car and sent all the current confusion to Professor Frank. So far he still has no idea about the working principle of the wooden box. A few minutes later, he received a reply.

"Have you heard of an animal called a rattlesnake?"
