Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a multi-protocol adaptive data acquisition device for ship air flow field measurement. Background technique [0002] At present, in the field of quantitative measurement of the air flow field at the stern of a ship, Western countries mainly adopt single-sensor measurement. The sensor is directly connected to the host computer. While the host computer receives the sensor data for collection, it uses multiple host computers to perform other synchronous data that needs to be measured. Data collection, data fusion and analysis after measurement, such as figure 1 Shown is the single-sensor measurement technique implementation structure, as figure 2 The implementation method of the single-sensor measurement technology is shown, including: (1) by arranging N wind speed sensors, attitude sensors, motion sensors, etc., and using multiple host computers to simultaneously collect...
