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

Abstract

The embodiment of the invention discloses a negative pressure control method and device, a storage medium, and an isolation ward. The isolation ward includes an exhaust device and a differential pressure sensor, which can obtain the first static pressure value in the isolation ward detected by the differential pressure sensor in real time. , according to the first static pressure value and the preset target negative pressure value, determine the fan speed adjustment value required for the negative pressure value in the isolation ward to reach the target negative pressure value, and adjust the fan speed of the exhaust device according to the fan speed adjustment value The wind speed is adjusted so that the negative pressure value in the isolation ward remains at the target negative pressure value. By setting the differential pressure sensor, the first static pressure value in the isolation ward can be effectively measured, and the fan speed of the exhaust device can be adjusted according to the first static pressure value and the target negative pressure value, so that the The negative pressure value is kept at the target negative pressure value, effectively maintaining the stability of the negative pressure value.

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, a storage medium and an 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 are still situations where the negative pressure in the interior space of the isolation ward is unstable, resulting in the leakage of the polluted gas inside the isolation ward to the outside. Contents of the invention [0004] Based on this, it is necessary to address the above problems and propose a negative pressure control method and device, a storage medium and an isol...
