Problems solved by technology

However, with the installation and operation of more and more megawatt-level wind turbines, vicious accidents such as wind turbine down towers also occur
The cause of the accident is partly because of the stress or structural damage on the fan tower due to improper operation during the process of entering and leaving the warehouse, transportation process or hoisting process of the fan tower; During the installation of the tower, there was a position shift, which resulted in the inclination of the wind turbine tower; the other part was that the wind tower had been operating under harsh conditions for a long time, and there were sudden changes in stress at the welds of the wind turbine tower, and the failure of bolted joints, etc. , eventually leading to the occurrence of tower collapse accidents
However, at present, a large number of researchers focus on the monitoring of the operating status of the wind turbine tower, ignoring the importance of the health status monitoring of the wind turbine tower before it is put into operation, which is important for the reliable operation of the wind turbine tower.

Abstract

The invention relates to a fan tower full life cycle state monitoring system, the fan tower full life cycle state monitoring system comprises a sensing layer, a transmission layer and an application layer, the sensing layer is composed of three acquisition units including a first acquisition unit, a second acquisition unit and a third acquisition unit, and each acquisition unit is composed of four acquisition nodes; the transmission layer is composed of an internet-of-things relay gateway, and the application layer is composed of a front-end display page, a database and a control module. The state monitoring system for the whole life cycle of the distributed fan tower drum has the functions of health state self-checking, state tracing, environment perception, air awakening and safety early warning, the limitation of monitoring the running state of the fan tower drum in the wind power field is broken through, the fan tower drum is loaded, transported, unloaded, hoisted and then installed and operated, and the whole life cycle of the distributed fan tower drum is monitored. The state monitoring of the whole life cycle also realizes the guidance function for the transportation and hoisting work of the fan tower.

Description

technical field [0001] The invention relates to a state monitoring system for the whole life cycle of a doubly-fed asynchronous fan tower. [0002] technical background [0003] With the rapid development of society, the shortage of traditional energy has become very serious. As a clean renewable energy, wind energy is widely used because of its abundant reserves and wide distribution. However, with the installation and operation of more and more megawatt-level wind power generating units, vicious accidents such as wind turbine down towers also occur. The cause of the accident is partly because of the stress or structural damage on the fan tower due to improper operation during the process of entering and leaving the warehouse, transportation process or hoisting process of the fan tower; During the installation of the tower, there was a position shift, which resulted in the inclination of the wind turbine tower; the other part was that the wind tower had been operating unde...
