Method and system for monitoring settlement of house foundation

The invention discloses a house foundation settlement monitoring method and system, and the method comprises the steps: obtaining a first height drop amount of a first sensor node in a preset time period and a second height drop amount of a second sensor node in the preset time period, determining a first monitoring line corresponding to a target sensor node according to a first difference value between the first height drop amount and the height drop amount of the target sensor node, and determining a second monitoring line corresponding to the target sensor node according to a second difference value between the second height drop amount and the height drop amount of the target sensor node; and taking an intersection point of the first monitoring line and the second monitoring line as a foundation settlement point, and generating coordinate information of the foundation settlement point. Accurate settlement information can be provided for settlement of the house foundation, so that subsequent maintenance by
