This invention discloses a precise differential pressure control system and method for clean areas in pharmaceutical production workshops, including a supply fan, an exhaust fan, a return air volume detection device, an air volume control valve, a differential pressure gauge, a gas flow meter, an angle sensor, and a monitoring module. The monitoring module stores a preset pressure range and a preset adjustment time for each clean area. When the monitoring module detects that the actual pressure value of the clean area is outside the preset pressure range, it generates a corresponding control command based on the magnitude of the deviation and the preset adjustment time. The control module receives the control command and adjusts the speed of the exhaust fan and the opening of the air volume control valve accordingly. This invention achieves intelligent adjustment of clean room pressure by controlling the air volume of the clean room through the monitoring module. Furthermore, the monitoring module can intelligently adjust the speed of the exhaust fan according to the actual pressure, thereby achieving rapid adjustment of the negative pressure clean room pressure.
