We propose a new model-independent strategy to calibrate the distance relation of Type Ia supernovae (SNe) and to probe the intrinsic properties of SNe Ia, especially the absolute magnitude $M_B$, based on strong lensing observations in the upcoming LSST era. The strongly lensed quasars can provide the Time Delay Distances (TDDs) and the Angular Diameter Distances (ADDs) to the lens galaxies, which can model-independently anchor the SNe Ia at cosmological distances and may in turn solve the Hubble constant issues locally related with Cepheids. We simulated 55 high-quality lens samples with $5\%$ uncertainties for the two kinds of lensing distances basing on future observation conditions. For the time delay distances and the angular diameter distances as the calibration standards, the calibrated $1\sigma$ uncertainties of $M_{B}$ are 0.1 and 0.03, respectively. Besides, we also consider an evolving distance relation, for example, caused by the cosmic opacity. In this case, the $1\sigma$ uncertainties of $M_B$ obtained by TDDs and ADDs are 0.12 and 0.08, respectively.
