The invention discloses a single-station real-time deformation monitoring method and monitoring system based on Beidou short messages, and the method comprises the steps: carrying out the networking with each monitoring station as a slave node and a data center as a main node, distributing a precise satellite clock and an orbit product obtained by the main node through Beidou short messages to each monitoring point, and carrying out the real-time deformation monitoring of each monitoring station; therefore, the communication cost among the monitoring points is reduced, the monitoring cost is reduced, and a real-time GNSS high-precision deformation monitoring solution under an open sea and offshore civil facility monitoring application scene without network coverage is realized; the receiver carries out PPP calculation on the basis of the received high-frequency satellite clock, so that the centimeter-level deformation monitoring requirement, even better than the centimeter-level deformation monitoring require
