The utility model relates to the technical field of foundation monitoring. The monitoring system is used for monitoring equipment foundation settlement and inclination. The system comprises at least one data acquisition unit, a control unit, a storage unit, a communication unit and a monitoring terminal, wherein the data acquisition unit comprises an angle sensor and a laser ranging sensor, and the control unit is in communication connection with the monitoring terminal through the communication unit, initializes the data acquisition unit according to initialization information and an alarm threshold sent by the monitoring terminal and feeds back an initialization result and alarm information to the monitoring terminal. The device is reasonable and compact in structure; the control unit judges whether the substation equipment settlement distance data and the equipment inclination data acquired by the data acquisition unit in real time reach alarm conditions or not according to set alarm thresholds; and alarm information is sent to a worker and an upper computer in real time, so that maintenance personnel can master equipment conditions and timely discover and process the equipmentwhen the equipment is inclined due to settlement, and the method has the characteristics of safety, labor saving, simplicity, convenience and high efficiency.
