Problems solved by technology

The formaldehyde release rate of different panel furniture is different. At present, formaldehyde monitoring is carried out by randomly or evenly arranging multiple formaldehyde monitors in the house to monitor the room, which increases the number of formaldehyde monitors. At the same time, due to the influence of airflow velocity, indoor temperature and humidity The concentration of formaldehyde will affect the monitoring data and reduce the monitoring accuracy. At the same time, if the formaldehyde monitor is continuously used for monitoring, it will not only reduce the service life of the formaldehyde monitor, but also increase energy consumption and increase the cost. Therefore, there is an urgent need for an indoor formaldehyde monitor. Concentration distribution and monitoring system to solve the above problems

Embodiment

[0019] Example: such as figure 1 As shown, an indoor formaldehyde concentration distribution and monitoring system, including an environmental simulation system and a formaldehyde monitoring module, a gateway and a data processor;

[0020] The environmental simulation system includes a server and a node monitoring module. The server has built-in Airpak software, which can analyze the airflow distribution of the pre-established physical model. The node monitoring module includes a humidity sensor, a temperature sensor and an airflow sensor. The outdoor interconnected position monitors the indoor air flow. The humidity sensor, temperature sensor and airflow sensor are all connected to the gateway, and the data is fed back to the data processor through the gateway. The data processor is connected to the server and feeds the data back to the server.

[0021] Among them, Airpak software has a variety of built-in models for direct selection, including turbulence models, forced conve...

Abstract

The invention discloses an indoor formaldehyde concentration distribution and monitoring system. The system comprises an environment simulation system, a formaldehyde monitoring module, a gateway anda data processor; the node monitoring module is used for monitoring indoor temperature, humidity and airflow flowing data, and transmitting the data to a server; the server performs simulation according to the actual physical model of the house through built-in Airpak software, therefore, the indoor speed vector and the air age are analyzed for obtaining the gas flow concentration distribution; based on the gas flow concentration distribution, the formaldehyde concentration distribution is judged; a user can conveniently and directionally arrange monitoring points at a simulation position withrelatively high formaldehyde concentration; the number of monitoring points is reduced, the monitoring efficiency and accuracy are improved, the formaldehyde sensor can be controlled to be turned onand turned off according to an Airpak software simulation result through the effect of the control switch, energy consumption and contact cost are reduced, and use is more convenient and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of indoor formaldehyde monitoring, in particular to an indoor formaldehyde concentration distribution and monitoring system. Background technique [0002] Formaldehyde is a widely used basic chemical raw material. It is commonly used in the production of resins, plastics, paints, explosives and fuels in industry. At the same time, formaldehyde is also a protein coagulant. In some cases, it will irritate the eyes, nose and respiratory system. Living in a high concentration of formaldehyde for a long time will damage the kidneys, liver and digestive system of the human body. In severe cases, it may cause leukemia and cancer. Formaldehyde can also cause children to grow slowly. The release cycle of formaldehyde in decoration materials can reach 3-15 years. The formaldehyde release rate of different panel furniture is different. At present, formaldehyde monitoring is carried out by randomly or evenly arranging ...
