The invention relates to a wireless vibration sensor optimized layout method for structure monitoring, which comprises the following steps of: firstly, calculating to obtain a real modal matrix of a monitored structure, then, establishing a wireless vibration sensor layout scheme evaluation function which simultaneously considers data validity and energy utilization rate, and on the basis, utilizing an improved firefly algorithm to evaluate the layout scheme of the wireless vibration sensor. The optimal layout scheme is searched and solved by adopting a movement strategy in which elastic movement, jumping movement and directional movement are coordinated, the calculation speed is high, the result quality is high, and a position which can best represent the vibration characteristics of the structure can be preferably selected from hundreds of selectable measuring points of the structure to carry out wireless vibration sensor layout; according to the invention, not only can the sensor be ensured to collect the
