The mode of operation of the equipment to reduce the unnecessary energy consumption in the area. And the state of human body activity in the space - relative to the degree of change of the output voltage signal of the pyroelectric human infrared sensor is proportional, the level of human activity is like the increase or decrease of the change in the space month b, based on This kind of physical property, according to the human body's active state, according to the pyroelectric type human body infrared sensing signal, the degree of change of the voltage signal of 14 201024736 is constructed to construct a kinetic energy change model, and the human activity of the model is analyzed and judged by monitoring and calculation. In this way, it is possible to break through the dual-judgment function of the low-cost pyroelectric human infrared sensor, which can only judge the presence and absence of the human body, and then upgrade to the ability to detect the multi-human activity state. When applied to an air conditioner, it can be used to control the power of the air conditioner without increasing the cost. Therefore, the patent application is proposed to seek the patent right. The structural features and embodiments of the present invention have been The detailed disclosure can fully demonstrate the progressiveness of the invention in terms of its purpose and efficacy. With the use value of the industry, and for the unprecedented use on the market, according to the spirit of the patent law, the present invention fully meets the requirements of the invention patent. Only the above is only the preferred implementation of the present invention. The scope of the invention is not limited by the scope of the invention, and all the changes and modifications made in accordance with the scope of the patent application of the present invention should still fall within the scope of the patent application of the present invention.
