The invention provides an automatic infusion monitoring method and system based on weight monitoring, and relates to the technical field of medical instruments. The method specifically comprises the following steps that the weight of liquid medicine of an infusion system is collected at the time interval of delta t, the infusion flow speed Vi is calculated, and the acceleration Xi m/s2 in the horizontal direction and the acceleration Yi m/s2 in the vertical direction of the infusion system are collected; presetting a first acceleration limit value J m/s2, a second acceleration limit value K m/s2, a maximum flow velocity Vmax and a minimum flow velocity Vmin; the average infusion flow velocity Vaverage in the buffer time period is calculated, the average infusion flow velocity Vaverage is compared with Vmax and Vmin, and the flow velocity is controlled to be reduced to a preset range or increased to the preset range; if a plurality of continuous V are all 0 on average, the infusion tube is locked, and an alarm
