Therefore, a method capable of recording the environment undergoing a change process is needed to develop an intelligent data acquisition system of the internet of things, which is carried by people for data acquisition.
According to incomplete statistics, about 80% of an adult spends indoors every day, and the quality of indoor environment is very important to physical and psychological health of people and is also closely related to behavior regulation of people. Currently, the evaluation of indoor environment quality is based on the current environmental quality standard. For example: the newly revised indoor air quality standard (GB/T18883-. However, almost all of the regulatory standards that govern indoor environment construction design consider a person as a "passive recipient of the environment," ignoring the person's active environmental conditioning behavior, while considering reaching a certain indoor environment state point as an ideal state. For these index limit regulations, such as "how appropriate indoor air temperature in winter? "derived from international recognition of" regarding comfort as a 'product', requiring service by an air conditioning system ". The index value is mostly from empirical evaluation, and also includes consideration of factors such as energy and economy. However, relevant researches indicate that the indoor environment requirement of people has the characteristics of dynamic property, periodic change, influence by individual environment adaptability and regional culture background and the like, and meanwhile, the adaptability of people to the environment and the environmental preference greatly influence the requirement.
