Building tower crane arm tip monitoring method and system based on satellite positioning

The invention discloses a building tower crane arm tip monitoring method and system based on satellite positioning. The system comprises: a monitoring parameter obtaining unit, which is used for obtaining north coordinates and east coordinates of all monitoring epochs measured by a monitoring station at an arm tip of a building tower crane; the horizontal arm length determining unit is used for determining the horizontal length of the tower arm of the building tower crane according to the north coordinate and the east coordinate of each monitoring epoch obtained by the monitoring parameter obtaining unit; the horizontal arm length deviation value determining unit is used for determining the horizontal arm length deviation value; and the early warning unit is used for giving an early warning prompt when the horizontal arm length deviation value is greater than an early warning threshold value. 本发明公开了基于卫星定位的建筑塔机臂尖监测方法和系统。该系统包括：监测参数获取单元，用于获取建筑塔机臂尖处的监测站测得的各监测历元的北向坐标、东向坐标；水平臂长确定单元，用于根据所述监测参数获取单元获得的各监测历元的北向坐标、东向坐标，
