Railway bridge formwork collapse safety monitoring method

The invention provides a railway bridge template collapse safety monitoring method, which comprises the following steps: measuring an original point position of a position where a monitoring terminal module is located; measuring a current position where a vertical rod reaches after displacement in a monitoring time interval t; receiving, by a remote computer, data monitored by the monitoring terminal module; gathering the feature vector of the monitoring point and feature vectors of n adjacent monitoring points to form a vector group; calculating a vector modulus Ha of the monitoring point and a mobile early warning threshold [H] to carry out early warning judgment, and judging whether an alarm is given or not after statistics is carried out on the proportions of the vector moduli of all the monitoring points greater than the early warning threshold. When the vector modulus is larger than the alarm threshold value, the remote central computer sends an instruction to the alarm module, the alarm module sends an
