Building ventilation method based on Internet of Things and fresh air system

Abstract

The embodiment of the invention provides a building ventilation method based on the Internet of Things and a fresh air system. The building ventilation method comprises the steps that air quality sensing equipment is set in a building according to a preset space distance, and air quality in the building is collected in real time and sent to a control center; geographic positions and action speedsof a user are collected by a user end of the building at preset time intervals, and sent to the control center; by using a building-user two-dimensional coupling use trend analysis method, the building ventilation mode is dynamically adjusted according to the trend that the user enters the building, and the building ventilation is completed before the user reaches the building; when the user enters the building, the building enters a continuous mute ventilation mode; and when the user leaves the building, the building ventilation is stopped. According to the building ventilation method based on the Internet of Things and the fresh air system, the ventilation efficiency is improved and the ventilation energy is saved by combining the technology of the Internet of Things and the actual ventilation characteristics.

Description

technical field [0001] The present application relates to the field of Internet of Things and ventilation control, in particular to a building ventilation method and fresh air system based on the Internet of Things. Background technique [0002] The Internet of Things, also known as the sensor network, refers to connecting any item with the Internet for information exchange and communication through radio frequency identification, infrared sensors, global positioning systems, laser scanners and other information sensing devices according to the agreed agreement. A network that realizes intelligent identification, positioning, tracking, monitoring and management. In the traditional building ventilation method based on the Internet of Things, the data collected by the sensor is generally sent to the user for control. On the one hand, the user determines the time and efficiency of the ventilation control, which has low accuracy and wastes energy; On the one hand, the real-time...
