With the development of technology, the development of medical devices is also very rapid. Like traditional Chinese medicine and the pulse has been rarely used now, the hospital most of the use of advanced technology, such as the sick most of the use of injections or intravenous drip infusion on the human body, but the infusion technique is not so advanced, people need the care of drip system, sometimes to a personal monitoring for many people, sometimes not even time to drop monitoring system, which leads to the occurrence of accidents, so the design idea is to design a timely monitoring system and a device without dropping speed of liquid is very necessary. The design of the system is to drop speed detection, this system can be very good for every bit of the detection and control, is a good solution to the frequent infusion process of the accident, the dropping speed is displayed on the LCD screen display. And the design of the systems speed control can be set by the button, the infusion speed control is completely automatic. Of course, this improved communication system can also be used for multiple systems, can through wireless communication, that is to say the data transmission between a master and slave control by a host to control. Once detected when there is no liquid drip or abnormal when the alarm from the station is to use a light emitting diode and a buzzer to achieve, and transmit the alarm signal through the serial transmission to the master station, through sound and light alarm monitoring software and buzzer. Drip controller MCU control system of this design, using 8051 single-chip mi
