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 comprises an exhausting device and a pressure difference sensor. A first static pressure value detected by the pressure difference sensor in the isolation ward can be obtained in real time. According to the first static pressure value and a preset target negative pressure value, a negative pressure value in the isolation ward is determined to reach a fan wind speed adjusting value needed by the target negative pressure value. The wind speed of a fan of the exhausting device is adjusted according to the fan wind speed adjusting value, and thus the negative pressure value in the isolation ward is kept at the target negative pressure value. By arranging the pressure difference sensor, the first static pressure value in the isolation ward can be effectively measured, the fan wind speed of the exhausting fan is adjusted according to the first static pressure value and the target negative pressure value, thus the negative pressure value in the isolation ward can be kept at the target negative pressure value, and the stability of the negativepressure value is effectively maintained.

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...
