AI Technical Summary

Benefits of technology

This patented technology improves an accurate way for controllers (such as Air Conditioner) that recognize how many peoples are inside buildings by analyzing image-based measurements like temperature and humidity levels collected during regular hours throughout their daylight cycles. By doing this, they can make better decisions about whether to turn off lights when there're no one around them or instead keep warm while still providing comfortable living conditions within these spaces.

Problems solved by technology

The technical problem addressed in this patented text relates to improving indoor environments' efficiency while minimizing energy wastage due to constantly changing occupancy levels based on realistic needs. This requires accurate monitoring over large areas where multiple individuals may be located simultaneously without sacrificing comfort level during peak hours when they require high volumes of clean outside air.

Abstract

The invention discloses an air conditioner and fresh air system predictive control method and system based on the indoor number of people. The control method comprises the following steps that a current indoor image and current indoor carbon dioxide concentration data are collected; according to the current indoor image and/or the current indoor carbon dioxide concentration data, the indoor numberof people is recognized; according to the current indoor carbon dioxide concentration data and the current indoor number of people, the temperature change amount and the carbon dioxide concentrationchange amount after the first preset duration are predicted; and the air conditioner and/or the fresh air system is adjusted according to the temperature change amount and the carbon dioxide concentration change amount. According to the control method, the indoor number of people can be accurately recognized according to the indoor image and/or the indoor carbon dioxide concentration data, and theair conditioner and/or the fresh air system can be accurately adjusted according to the indoor number of people, so that the accuracy of the number identification of people is effectively improved, then the accuracy of predictive control of the air conditioner and the fresh air system is improved, and the effects of being simple and easy to realize are achieved.
