An intravenous drip monitoring system that includes a storage module, an operation interface, a weighting module and a processing module is provided. The processing module is configured to perform the steps outlined below. (A) A monitoring-initialization signal is received. (B) A loaded weight is measured by a weighting module. (C) The loaded weight is assigned to be an initial weight and a current weight respectively when the loaded weight is smaller than a cleared weight. (D) An alarm weight is calculated such that when the alarm weight is not larger than a predetermined minimum alarm weight, the predetermined minimum alarm weight is assigned to be the alarm weight. (E) The loaded weight is measured by the weighting module and the loaded weight is assigned to be the current weight. (F) When the current weight is not smaller than the alarm weight, the step (E) is performed. (G) When the current weight is smaller than the alarm weight and is not smaller than the cleared weight, an alarm module generates an alarm signal and the step (E) is performed. (H) When the current weight is smaller than the cleared weight, a calibration is performed on the weighting module to reset the weighting module to zero and the step (C) is performed.一種點滴監測系統,包含:儲存模組、操作介面、測重模組及處理模組。處理模組配置以:(A)接收起始監測訊號;(B)量測承載重量;(C)承載重量小於清空重量時,使承載重量為起始及當下重量;(D)計算的警報重量不大於預設最小警報重量時,使警報重量等於預設最小警報重量;(E)測重模組量測承載重量做為當下重量;(F)當下重量不小於警報重量時,進行步驟(E);(G)當下重量小於警報重量、不小於清空重量時,警報模組產生警報訊號,進行步驟(E);(H)當下重量小於清空重量時,歸零校正測重模組,進行步驟(C)。1‧‧‧點滴監測系統100‧‧‧操作介面100A-100D‧‧‧按鍵101‧‧‧起始監測訊號102‧‧‧測重模組103‧‧‧結束監測訊號104‧‧‧儲存模組105‧‧‧暫停監測訊號106‧‧‧警報模組107‧‧‧回復監測訊號108‧‧‧處理模組109‧‧‧設定監測訊號130‧‧‧應用程式151‧‧‧承載重量152‧‧‧清空重量153‧‧‧未清空警報訊號154‧‧‧起始重量155‧‧‧當下重量156‧‧‧警報重量157‧‧‧點滴袋重量158‧‧‧臨界重量159‧‧‧最小警報重量160‧‧‧警報訊號
