Design of Intelligent Control System for Negative Pressure Isolation Ward

In the early days of the new crown epidemic, many medical staff were infected while treating patients, and if negative pressure isolation wards were used, it could effectively reduce the possibility of medical staff being infected in large numbers. Starting from the particularity of the negative pressure isolation ward, this project completes the design of the intelligent control system of the negative pressure isolation ward with reference to the environmental indicators formulated by the state. The system uses the embedded system to collect and process the environmental data of the negative pressure isolation ward, and combines the Internet of Things wireless communication technology to transmit the relevant information to the host computer for realtime display through wireless means; The system can automatically control and adjust the equipment in the ward according to the air pressure data, temperature and humidity data of different areas of the negative pressure isolation ward detected in real time; The system alerts when it detects that the environment has changed abnormally and exceeded the threshold set by the system.
