Wireless sensor placement method for wind-induced bridge vibration monitoring

The invention provides a wireless sensor placement method for wind-induced bridge vibration monitoring. The method comprises the following steps of: firstly simulating a wind field on the basis of a bridge finite element model and a standard wind spectrum, and carrying out calculation to obtain a wind-induced bridge vibration response by adoption of a wind-induced bridge vibration response time domain calculation method; calculating a contribution degree, for the wind-induced bridge vibration, of each selectable measurement point, drawing a contribution degree curve of each selectable measurement point, and arranging wireless sensors by taking peak points and valley points of the contribute degree curves as key measurement points; and further uniformly arranging relay measurement points as few as possible between the key measurement points and between the key measurement points and a data aggregation node of a data processing center, so as to realize the wireless sensor placement of wind-induced bridge vibrat
