Abstract

The invention discloses a field measurement device for a positive-pressure forced draught blower. The device is characterized by comprising an air pressure measurement module, a micro-controller module, a display module and a control output module. The air pressure measurement module, the display module and the control output module are connected to the micro-controller module. The air pressure measurement module comprises a sensor power supply circuit, a sensor U and a signal amplification circuit, wherein the sensor power supply circuit, the sensor U and the signal amplification circuit are sequentially connected together. The sensor power supply circuit comprises a voltage conversion circuit and a current source circuit. Compared with the prior art, during the air pressure measurement process, the stability is better and the precision is higher. Meanwhile, the safety of the working field is ensured.

Description

technical field [0001] The invention relates to the technical field of air pressure measurement of a positive pressure blower, in particular to an air pressure measurement of a positive pressure blower. Background technique [0002] Positive pressure blower is the blower pointing to the air supply in the escape corridor. It sends the outdoor wind pressure into the room. When a fire breaks out in a building, a large amount of smoke, carbon monoxide and other toxic gases will be produced and the line of sight will be blocked, and the positive pressure blower will be used to supply the high-rise building front room, shared front room, elevator front room, smoke-proof stairwell, closed basement, and underground refuge. Wait for the air supply from the escape fire stairs, so that the indoor smoke cannot reach the stairs, creating conditions for people to escape. [0003] The positive pressure blower needs to accurately monitor and control the space pressure difference. The exis...
