Abstract
The invention relates to a testing method of a blower fan state measurement and control system. The testing method comprises a step 1 that a differential pressure sensor, a static pressure sensor, and a torque sensor output detected data to a PC data acquisition card; a step 2 that the PC data acquisition card acquires atmospheric pressure, temperature, and humidity; a step 3 that the PC data acquisition card is integrated with a computer and outputs acquired data parameters to the computer and the computer computes data and draws a performance curve; a step 4 that the computer outputs a control signal after processing the data, the control signal sends information to a frequency converter via the PC data acquisition card, and the frequency converter outputs signal frequency in order to achieve automatic regulation and control of the rotating speed of a blower fan; and a step 5 that after the frequency of the frequency converter is changed, change information is output to the computer via the PC data acquisition card. The testing method is convenient system operation, and capable of automatically acquiring and processing information signals, automatically drawing the performance curve, preventing man-made reading and computing errors, improving testing precision, and achieving automatic adjustment of the rotating speed of the blower fan.
