Description

Intelligent passenger control device based on microwave imaging technology

Technical Field

The utility model relates to the field of artificial intelligence, in particular to an intelligent passenger control method and device based on a microwave imaging technology.

Background

With the continuous improvement of living standard of people, the demands of traveling and going out are continuously improved, and the hotel industry is always in an increasing situation. But the homogenization is serious, and the competition is strong and the problems and challenges facing the hotel industry. The intelligent transformation of hotels is an important trend of hotel development, on one hand, the living experience of residents can be improved, the competitiveness and the profit capability of the hotels are enhanced, on the other hand, the internet of things technology and the intelligent technology are introduced, hotel resources (such as energy consumption, personnel cost and the like) can be saved, and the operation cost of the hotels is reduced.

The current hotel intelligent system, namely 'intelligent' is a hotel intelligent guest control system which is manufactured based on a natural semantic recognition technology and combined with an internet of things technology, and guests control facilities in a guest room, such as lights, curtains, televisions, air conditioners and the like, through active awakening and active instructions. This approach can be somewhat convenient for guests to control the facilities of the guest room, but all instructions require the guest to issue actively, either by voice or by small programs. In some situations, the requirements of the client cannot be well met, for example, the client cannot recognize the accent problem, for example, the client cannot speak loudly or the client cannot speak or is inconvenient, and the like in some situations, so that the current perception of the client is not good enough and intelligent. While the current mature scheme is performed by a camera in view of actively monitoring the status of guests, relying on a perception system with motion capture and gesture recording functions, in hotel and home scenarios, the sensitivity of the client to privacy results in the inability to deploy the camera. And therefore can only be performed by other, non-imaging, motion capture mechanisms.
