Description

technical field [0001] The invention relates to the field of integrated monitoring of wind power generation systems, and is a vertical axis wind power generation test device based on distributed detection and data judgment. Background technique [0002] "In order to develop equipment, testing must go first." Small and medium-sized wind power generation equipment is inseparable from verification and testing in the process from design, trial production to production and maintenance. However, due to the natural particularity of wind energy utilization, the data collection process based on manual and wired transmission methods is extremely inconvenient, whether it is the wind tunnel test in the early stage of research and development, or the on-site operation monitoring of the prototype or product.

Problems solved by technology

However, due to the natural particularity of wind energy utilization, the data collection process based on manual and wired transmission methods is extremely inconvenient, whether it is the wind tunnel test in the early stage of research and development, or the on-site operation monitoring of the prototype or product.

[0003] The distributed multi-sensor connection process of the wind power generation system based on the wired transmission method is extremely cumbersome and complicated, and the labor intensity of the testers is high

Testing in the narrow space of the wind tunnel will also cause distortion of the local wind field due to the different routing methods of the wires, which will affect the test accuracy, and even cause the winding of the rotating shaft due to the falling of the wires, resulting in serious accidents

At the wind power operation site, due to the harsh geographical and meteorological conditions for the installation of the unit, such as high ground and roofs in the suburbs or urban areas, long-term manual data collection is extremely inconvenient, and excessively long wires will also cause serious damage.
