The invention discloses an intelligent urine volume measuring system based on ultrasound, and belongs to the technical field of medical apparatuses and instruments. When the intelligent urine volume measuring system based on the ultrasound is adopted, the urine volume of a patient can be accurately recorded, manual participation is not needed in the measuring process, safety and reliability are achieved, and medical care quality and medical care efficiency can be effectively improved. The intelligent urine volume measuring system based on the ultrasound comprises ultrasound receiving and transmitting units, a control unit and a container for containing urine, wherein the container for containing the urine is of a central symmetry structure, four or more ultrasound receiving and transmitting units are symmetrically arranged on the top of the container along the center of the container, and each ultrasound receiving and transmitting unit is connected with the control unit; when the volume of the urine in the container needs to be measured, the ultrasound receiving and transmitting units arranged on the top of the container are started to send transmitting waves out, the transmitting waves return to form reflected waves after reaching the liquid surface, and the reflected waves are received by the ultrasound receiving and transmitting units; the control unit obtains the time interval between the time when the ultrasound receiving and transmitting units send the transmitting waves out and the time when the ultrasound receiving and transmitting units receive the reflected waves through measurement, and the volume of the urine in the container can be further obtained.
