"Positive pressure pipeline, then this is likely to be a differential pressure transportation pipeline."

Absolutely professional in the field of engineering equipment, Xiaohella quickly reminisced about the differential pressure transportation pipes commonly used in space docks according to the positive pressure mechanism.

This is a way to reduce the number of components, reduce the volume of pipes, and improve the use of space.

The composition mode of the differential pressure transportation pipeline is to use the pressure difference inside the pipeline to push the inner cavity transportation bridge, which can reduce a large number of power structures, as long as the channel as a whole has good air tightness.

For space units such as spacedocks and starships, the design of structural airtightness has always been an extremely important part, so the differential pressure transportation pipeline with various advantages is generally the first choice for high-speed material transportation inside space facilities.

"Sister, if the differential pressure transport pipe, the internal positive pressure will not be low, if the pressure relief work is carried out rashly, how to deal with the high-speed transportation bridge in the inner cavity?"

"Let me think about ......"

At this time, the White Snake assumed the role of decision-maker, while the Green Snake took on the role of technical consultant as a professional engineer, and the two worked together to release the computing power of the body and began to think.

Since it is a differential pressure transport pipeline, if they first perform the pressure relief operation at the outlet end, it will be difficult to handle the transport bridge equipment at the inlet end.

Because they do not know the airtight measures at the rear end of the inner cavity transport bridge, the worst possibility is that when they touch the bridge fixing mechanism, they will be directly shot back by the high-pressure driven transport bridge, resulting in damage to the body.

However, this speculation is based on the fact that the airtight facilities in the rear range have failed for a long time, and the transport bridge may not wait for the double snakes to enter, and the transport bridge will be directly photographed.

Although there must be an emergency deceleration mechanism at the outlet end of such a way, it is really hard to say whether those devices can work normally after hundreds of thousands of years.

However, according to the preservation of Kunlun relics and equipment seen so far, White Snake believes that the probability of failure of these equipment should not be high, because Kunlun's material science and technology are too advanced, coupled with such an excellent inert gas protection environment, it is not possible for each device to maintain good working condition for hundreds of thousands of years.

"Hela, you find the outlet section pressure relief valve first, this time you can't use a rough demolition method, which is not conducive to our next actions."

Since the basic logic of this exit safety door is consistent with the basic logic of federal mechanical engineering, it must have a manual opening mode under the condition of energy supply, which is an inevitable safety redundancy technology.

It is the best choice to use the normal operation of the differential pressure channel structure to open this safety door, if the air tightness is invalidated by demolition means, the subsequent air pressure balance problem will be quite tricky.

The demolition method that has been used before is because compared to the outside world, the outer layer of defense through which the double snake passes belongs to the low-pressure area, and it is enough to do a good job of airtight protection at the entrance of the second-level defense layer, and the isolation door that has been demolished and restored all the way can also play a role in maintaining air pressure safety.

The White Snake has completely determined that the Kunlun Ruins are the space unit facilities of an unknown civilization, and along the way, a large number of airtight gates, multiple self-discipline maintenance machine maintenance rooms, and obvious blocked outer structure, all show that the internal structure design concept is to meet the needs of space missions, and the design concept of the surface base in general is completely different from the space unit because of the existence of star gravity.

The neat and orderly internal environment, if it weren't for the data provided by gravity to the accelerometer of the twin snakes, they would basically not be able to distinguish between the top and the bottom, coupled with the perfect airtight measures, with the volume of the current ruins, the white snake could determine the name of its Kunlun spacedock.

And the safety verification logic of the space facility is that they can open the operation space of this typical vane safety door normally.

"According to the safety logic of space facilities, the sub-module system should be in an open state of authority when the line energy supply and safety data link are lost, as long as the control panel is found and the backup energy supply interface is connected, the normal operation of this differential pressure transportation channel should be restored."

Hella quickly gave a professional analysis of the safety logic, because the environment of the space facility and the surface facility are different, and the safety logic of the two subsystems is completely opposite.

Security measures at surface bases are generally locked when the primary link is lost, while space facility subsystems are open to permissions.

The logic behind it is because the security logic of the ground base is to take security as the first goal, and the loss of the main signal link indicates that the base host has suffered a serious accident, and in this case, for the sake of base security, this channel must be automatically locked.

The space facilities are different, the safety logic of the space environment should be considered for the survival of personnel, and it is generally a modular design for structural redundancy, so that the space dock can still operate normally as long as the core structure is not damaged when it is damaged.

In these areas that are lost, the permission verification mechanism such as the channel will not retain the local permission data, and this important permission verification must be handed over to the permission security host at the core of the facility by the data link, and the permission data will not be stored on the secondary host of the distributed security verification network, because if the distributed security host of each module stores the permission data locally, then the data transmission between the hosts may be hijacked and deciphered. Or a third party can gain access to permission data by hacking into the secondary security host of the space dock module that has been lost.

A typical example is the Federation's flagship-class warship, the core security host of this type of space unit has the authority identification code and security verification program of the entire fleet level inside, if the enemy obtains the fleet module structure through damage and extracts local data from the secondary security host, the security verification of the entire fleet will be threatened.

The above is the consideration of authority security, and from the perspective of personnel preservation, in the case of the loss of security host link in this kind of channel, the overall module loses the main energy supply, and if the authority is automatically locked, the escape of internal personnel is a big problem.

Therefore, the logical choice in this case must be an open state of authority without verification, and the internal personnel unit needs to conveniently open the passage to escape before the backup energy is exhausted, or wait for friendly rescue inside the hull.

The open permission state is sufficient to meet the needs of both needs, and the internal personnel can open the area where the original permission is insufficient, and the rescue volume can also use the emergency energy interface to supply energy to similar channels for opening operations, so as to rescue the internal personnel.

The current Kunlun spacedock is very much in line with this emergency state of detachment from the core, without any energy and communication connections, and the subsystems at all levels are in a normal automatic shutdown state, according to the safety logic, the permissions should be open by default, which gives the two snakes the possibility of opening the current differential pressure channel safety door normally.

Hela, under Roselle's guidance, quickly opened a covered panel near the security door, inside which was clearly an energy supply interface and a mechanical switch structure.

Mechanical structure has always been synonymous with reliability and stability, and the reliability of low processing difficulty and high stability attributes runs through the history of scientific and technological development.

This is to talk about the characteristics of scientific and technological development, the development of technology is accompanied by the elimination and coverage process of backward technology, but this is relative to the functional requirements.

If the current technology has met the functional requirements, the subsequent development will generally only carry out relevant optimizations, unless the functional requirements change, and rarely change the use of the technology.

For example, the easiest way for object A to drag object B is to tie a rope to both of them.

In the absence of other requirements, this rope is the best way to link, then what needs to be optimized is only the physical properties of the rope itself, as well as the connection method, and the easiest way to cut this rope is a pair of scissors.

"Rope", "interface", "scissors" can be extended to represent a certain means of application, according to different functional requirements to represent different specific technologies.

For example, communication needs, the communication cable or wireless channel is this "rope", and the latter is generally used when the advantages of the wireless channel are greater than the wired link.

Both an alloy knife and a laser cutter have "scissors" properties, but if they are only used to cut apples, it is estimated that only some boring humans will choose to use a laser cutter.

The logic behind these theories is that technology is to serve needs, and there is no need for a type of demand to use more advanced application techniques that are beyond the scope.

Is the civilization behind the Kunlun spacedock high-tech? As far as the internal materials seen by the twin snakes, the autonomous robots, are indeed very high.

Advanced civilization means a more accurate and efficient use of resources, and it does not mean that high-end technology must be used everywhere to show the advantages of science and technology.

In addition to the metamorphosis physical properties that need to meet the support tasks, the general wall covering is made of lightweight polymer composite materials that can be easily broken by the green snake, and the requirements for wall covering materials do not need strength themselves.

Isn't there a better technology than differential pressure transport? There must be, the electromagnetic transportation channel is very mature even if it is Federation, but the unavoidable properties of additional magnetic ring power supply equipment and magnetic field interference inside the channel are obviously not applicable in some transportation scenarios of the space dock.

Moreover, differential pressure transportation makes use of the airtight structure inside Kunlun itself, which reduces the space occupied by the equipment, and it may be more convenient and faster to transport the specified materials, which is enough to meet the needs of the task, and there is no need to use other more advanced channel technology.

If such short-distance directional transportation adopts the space jump technology that only science fiction can have, then the civilization behind the Kunlun spacedock can only be said to be very science fiction, and the twin snakes are estimated to not be able to enter at all.

After verifying the safety logic idea, the next work is very clear, return to the link terminal between the devices, synchronize the data with the AI host, let HELLA manufacture the cable that meets the corresponding emergency power supply interface, and then drag it to the automatic distribution center to link the safety door to see if the differential pressure channel can work normally.

If you're lucky, maybe just press the emergency switch, and the passage will be up and running, and the twin snakes can take the transport bridge directly to the inner ring facility of the Kunlun spacedock.

If she doesn't forgive, she will gnaw on the difficult bone of the passage security door.
