Negative pressure control method and device for isolation ward, storage medium and isolation ward

Abstract

The embodiment of the present invention discloses a negative pressure control method and device for an isolation ward, a storage medium, and the isolation ward. When the main exhaust device is operating normally, the first static pressure value in the isolation ward detected by the differential pressure sensor is obtained; according to The first static pressure value and the target negative pressure value adjust the fan speed of the main exhaust device; when a failure of the main exhaust device is detected, the standby exhaust device is started, and after the standby exhaust device starts normally, the Acquiring the second static pressure value; adjusting the fan speed of the backup exhaust device according to the second static pressure value and the target negative pressure value. By setting the differential pressure sensor, the main exhaust device and the backup exhaust device, the negative pressure value in the isolation ward can be kept at the target negative pressure value, ensuring that the negative pressure value in the isolation ward is stable, and making the main exhaust device appear In the event of a failure, the ability to use a backup exhaust enhances the reliability of the isolation ward.

Description

technical field [0001] The invention relates to the technical field of negative pressure control, in particular to a negative pressure control method and device for an isolation ward, a storage medium and the isolation ward. Background technique [0002] Patients with respiratory infection or other infectious diseases need to be treated in isolation wards. Negative pressure isolation technology is usually used in isolation wards, which means that the internal and external spaces of the ward are kept in a negative pressure state, so as not to make the ward Contamination control inside leaks to outside. [0003] However, there is still the situation that the negative pressure in the space inside the isolation ward is unstable, resulting in the leakage of the polluted gas inside the isolation ward to the outside, and there is also the problem that the exhaust fan fails and the entire isolation ward cannot be used, and the reliability is low. Contents of the invention [0004...

Problems solved by technology

[0003] However, there is still the situation that the negative pressure in the space inside the isolation ward is unstable, causing the polluted gas inside the isolation ward to leak to the outside, and there is also the problem that the exhaust fan fails to make the entire isolation ward unusable, and the reliability is low.
