Method and system for calculating positions of distributed monitoring sensors in timber structure building

The invention discloses a method and a system for calculating positions of monitoring sensors arranged in a timber structure building. The method comprises the following steps: constructing an analysis model; the analysis model is corrected according to the tenon pulling data, load influence analysis under the dead load working condition is conducted, and if the relative displacement of the wood component is larger than a corresponding preset relative displacement threshold value, the position of a displacement sensor is set; the analysis model is corrected according to the compression deformation data, the inclination deformation data and the cracking data, stress analysis is carried out under the working conditions of dead load and uniform load of the whole roof truss, and if the stress of the wood component is larger than a corresponding preset stress threshold value, the position of a stress sensor is set; the position where the crack sensor is to be arranged is the crack existing in the detection result;
