System and method for managing facilities

A method for managing facilities, the method comprising the steps of:

• detecting an acoustic event in a compartment of a facility;
• extracting a respiratory disease symptom of a user in the facility from the detected acoustic event;
• assessing at least one of intensity, frequency, and duration of the respiratory disease symptom of the user to determine a severity of the symptom;
• assessing a ventilation status of the facility indicated by a concentration of carbon dioxide;
• generating infection risk information associated with an infection risk of a next user expected to use the facility from the severity of the symptom and the ventilation status of the facility;
• transmitting the infection risk information to at least one of an external user terminal, the external server, and a third party via a network;
• and
• transmitting instruction to improve the ventilation status of the facility to at least one of the external server, the facility terminal, the external user terminal, and the third party via the network based on the infection risk information, and
• wherein the transmitting the instruction comprises transmitting the instruction when the severity of the symptom is high while the infection risk is low.

A system for managing facilities, the system comprising

• an acoustic event detector including an acoustic sensor for detecting an acoustic event in a compartment of a facility,
• a facility terminal electrically connected to the acoustic event detector, and
• an external server communicating with the facility terminal via a network,
• wherein at least one of the facility terminal and the external server comprises a processor,
• the processor is configured to implement the steps of:
• extracting a respiratory disease symptom of a user in the facility from the detected acoustic event;
• assessing at least one of intensity, frequency, and duration of the respiratory disease symptom of the user to determine a severity of the symptom;
• assessing a ventilation status of the facility indicated by a concentration of carbon dioxide;
• generating infection risk information associated with an infection risk of a next user expected to use the facility from the severity of the symptom and the ventilation status of the facility;
• and
• transmitting the infection risk information to at least one of an external user terminal, the external server, and a third party via the network, and
• the processor is configured to change a frequency of the transmitting the infection risk information in accordance with the infection risk.
