Since there are many flaws in traditional blood fractionation method, such as a complicated operation, the results are not accurate, and non-standard information recording, etc. The low-cost blood fractionation machine has good research significance. This paper proposes a low-cost control system of automatic blood fractionation machine to solve these problems. Up to more than one hundred of automatic blood fractionation machines can work together through CAN network connections, and all these machines can be centralized control by a PC. The control system of this machine is designed based on C8051F040 MCU, a kind of SOC with many AD interfaces, DA interfaces, digital IO interfaces, etc. For the scalability and flexibility of the system, each sub-process of blood fractionation is realized by a sub-program, and the whole fractionation process can be flexibly programmed by users for special demand. The software of the control system uses a modular design method, propoes four states to realize workflow control. In order to meet the requirements of blood bank blood fractionation requirements, the process of blood fractionation is accurate, precise, and standard, the records of every produced blood component bag is very detailed, and can be easily traceable.This system can produce the blood components meeting to the management standard of the Blood Bank, and has been shown adaptable in various blood bag systems.
