The new high-tech doors of the modern era are very user-friendly. In order to fully show its humanity, I will introduce it carefully here.

It's annoying that everyone has forgotten their keys when they go out, because it means you may have to wait outside the door for most of the day, possibly climbing over the courtyard wall to get in. You can't go into your own house, do you think it's a very hot thing? High-tech doors solve this problem very well.

Just like regular doors, high-tech doors can be opened with a key.

When the owner forgets to bring the key, the security system in the door will activate the sound recognition system, and make a judgment based on the owner's pre-recorded voice: whether it is the owner outside the door. Of course, voice recognition has its limitations, for example, after a person has a cold, the voice will change, at this time the security system will not recognize you, it will recognize you as a stranger, and warn you.

When the voice recognition system fails to let you pass the identity verification, you can also use a third method of unlocking, which is face recognition. The face collection system in the hidden part will make a judgment based on the collected face information, and if the collected face information is consistent with the pre-stored face information, the door will automatically open and welcome you with a very warm voice. It cannot be ruled out that the man or the hostess will have plastic surgery for some need; After plastic surgery, the facial information will change, so it is destined to be stopped at the door and "sigh".

But don't worry, you still have one magic weapon that you haven't come out, and that is fingerprints.

Each person's fingerprint is unique in the world, and no one can imitate a fingerprint like a counterfeit key; In addition, fingerprints will not be lost like a key, after all, it grows on a person's body, and it is not easy to lose it even if you want to. Therefore, when the above methods fail to open the door, the fingerprint recognition system will solve the problem with full authority.

Of course, if even the fingerprint recognition system can't confirm your identity, it can only be said that the security door is malfunctioning, at this time you only have two ways to choose, one is to smash the high-tech door to a pulp, still install the ordinary security door, and the other is to find a lock company.

This is a general home door, which is not suitable for our hotel. The hotel is a relatively public occasion and has functions that are more in line with the requirements of the public.

Like most hotel doors, the high-tech door is glass-like and transparent, and it should be noted that it is not made of carbon. From a distance, this door is no different from an ordinary glass door, but in essence, within the range of 10 meters and 180 degrees in front of the door, the collection function of the door is distributed everywhere, which means that there is an invisible door within the range of 10 meters and 180 degrees in front of it.

This invisible door has several powerful functions.

One is the purification function. When people walk into the hotel from the outside, they will inevitably carry some germs brought by public places, and when guests pass through the invisible door, it will automatically generate the corresponding germ buster according to the relevant information and release it to achieve the purpose of eliminating them. Of course, these generated substances are all released in the form of gases and do not affect the mood of the guests. It is worth mentioning that the germ database in the invisible door is connected to the world's largest and most complete "Hanyu virus and germ database", which is updated every half hour, and its ability to isolate virus germs can be said to be super strong.

The second is the beautification function. This beautification simply refers to the beautification of body odor and body fragrance. Regardless of whether the guests who come to the hotel are ordinary people or dignitaries, when passing through the invisible door, it will attach an aroma with improving functions to you according to your mood, so that you can dine in a more comfortable feeling. The invisible door's parameters to know the mood of visitors come from the numerical control center - hidden in the door frame, which stores all kinds of information. For example, what is the facial expression when you are happy, what is the heart rate in general, the flickering frequency of the pupils, the normality of the posture, and so on. These are dead bars that are prone to error, and more reliable information comes from the analysis of human brain electrodes, which distinguish between good and bad moods according to the fluctuations of the electrodes. These are done invisibly and within three seconds before the guest enters the door, including analyzing the information and releasing the aroma.

The most valuable is the third bell function, the health monitoring function. Within a few seconds of passing through the invisible door, the invisible door will make a comprehensive assessment of the visitor's health status based on the secretion of sweat and the exhaust air exhaled, so as to make corresponding dietary recommendations. For example, when the invisible door detects that the blood lipids of the visitors are high, the guests will be advised to eat less foods with high fat content; For example, when the weight of the visitor is much higher than the average weight, the system will prompt the guest to eat more low-calorie food or increase the amount of exercise...... This information will be fed back to the guest's seat – there is a place like a monitor on the seat, which I will explain in my diary later – so that the guest can use it as a reference when ordering.

After eating, guests often forget to bring things with them, such as satchels, clothes, etc. This is a hassle, as there is a half-chance that you won't be able to get it back after losing it. The use of sliding doors greatly reduces the occurrence of this situation. When a guest leaves their seat, a chair or sofa or dining table will send a message about what the guest has forgotten to the invisible door, and a reminder will be sent when the guest passes through the invisible door. Of course, the same hint will be given by the chair or sofa or the dining table before. This will be described in the diary later.
