Design Of Fresh Air Monitoring System Based On Internet Of Things

The fresh air system is based on the use of special equipment in the interior of the building to supply fresh air to the interior,and discharge the original indoor air to the outside.In the process of air supply and exhaust,the special equipment is used for filtering,disinfection,sterilization,oxygenation and preheating.Through the continuous generation of modern fresh air flow,the indoor air quality has been effectively improved,which not only meets the needs of indoor fresh air ventilation,but also reduces the impact of outdoor haze air pollution on human body,as well as the harm of indoor decoration slow-release harmful gas to human body in confined indoor space.However,the existing fresh air system mainly has requirements on fresh air volume and other parameters,and there is still a lot of room for improvement in indoor air quality data acquisition,integrated control of air supply equipment,energy saving and consumption reduction of equipment.This paper studies the current situation and existing problems of the fresh air monitoring system,and puts forward the overall framework and design scheme of the fresh air monitoring system based on the Internet of things.The central controller chip,node sensor and control module,transmission network module in the design of fresh air monitoring system are selected.According to the actual demand analysis of the design control system,the wireless and mj-ethernet01 wired intelligent monitoring network system based on esp-wroom-02 d is determined to adopt STM32 single chip microcomputer as the core of the central controller,seven in one air quality detection sensor as the data acquisition.This paper designs a new wind system based on the Internet of things control,including hardware controller circuit,network communication circuit,sensor acquisition and output control hardware circuit and supporting software control design,The integrated control mode enhances the work efficiency of the fresh air system,while greatly reducing energy consumption,and maintains the original comfort and various functions of the fresh air system.At the same time,it also has corresponding development and application in the remote cloud monitoring function and mobile real-time human-computer interaction function.
