The invention relates to a boiler ventilation test data on-line acquisition system and an analysis and processing method. The analysis and processing method includes the following steps that: differential pressure, pressure, and temperature in a plurality of test pipelines of a boiler are acquired in real time through field acquisition components; the signals are sent to a data processing center;the data processing center performs calculation so as to obtain air volume, air speed, air speed deviation and the air volume correction coefficient of a total pipeline connected with four test pipelines; and a field test adjustment actuator receives a test instruction issued by the data processing center and then adjusts the air volume in the test pipelines until measurement under 0 to 100% workconditions is completed, so that pipeline performance curves under the corresponding working conditions can be obtained, and a corresponding control model is established according to the pipeline performance curves, and accura
