Monitoring, tracing and early warning regulation and control system and method for virus transmission in a building

Abstract

The invention relates to a monitoring, tracing and early warning regulation and control system and method for virus transmission in a building. Indoor and outdoor environment parameters of a buildingcan be monitored in real time, physiological indexes of a human body are obtained in real time, the health state of the human body is judged, and the moving track and the droplet propagation track ofeach person are obtained, so that suspected infected persons and people in close contact with the suspected infected persons are timely and accurately recognized, and meanwhile response measures are taken for the suspected infected persons and people in close contact with the suspected infected persons. Besides, the propagation risk of the current indoor environment can be evaluated, the indoor environment is ventilated and purified according to the propagation risk evaluation result, the suspected infected person and the local area of the close contact person are effectively ventilated and purified, and the propagation risk is reduced. Building indoor environment parameters, human body health characteristics and virus transmission risk assessment are combined, the building indoor environment state can be accurately judged, suspected infected persons and people in close contact with the suspected infected persons can be recognized in real time, and overall ventilation purification andlocal purification treatment on the indoor environment are achieved.

Description

Technical field [0001] The invention relates to the field of virus transmission monitoring, traceability and early warning regulation, and in particular to a system and method for monitoring, tracing and early warning regulation of virus transmission in buildings. Background technique [0002] At present, building control mostly takes the environmental threshold set by the user as the control target, and considers the entire room according to the lumped parameter method. With the emergence of the new crown pneumonia epidemic, this user-set control method that ignores local environmental parameters is difficult to meet the epidemic prevention control the target. Generally speaking, there are the following problems: [0003] First, the method for the user to set the control target has a single target parameter, and the optimization target is unreasonable. Physical quantities such as temperature and carbon dioxide concentration are often used as control parameters of HVAC equipment....

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a system and method for monitoring, traceability and early warning control of virus transmission in buildings, which overcomes the problem of using the environmental threshold set by the user as the control target in the prior art and considering the indoor environment according to the lumped parameter method. The parameters are difficult to reflect the risk of virus transmission, and it is difficult to control the indoor environment to meet the goal of epidemic prevention and control; the indoor environment monitoring method is single, and it is difficult to judge the movement trajectory of the virus source and the transmission route of pollutants; the monitoring and control using the lumped parameter method is the whole The parameters of the control unit ignore the local environment, thereby underestimating the risk of exposure to the virus. At the same time, a new technology combining environmental monitoring in the building and identifying human health characteristics is adopted to realize the monitoring, traceability, early warning and regulation of virus transmission in the building.
