英文摘要：

Micro-injection pump is the conventional apparatus used in the organization of medical treatment and health protection. Aiming at developing an automated liquid delivery system ~vith perfect performance and high precision, which can control multiple pump injection of acceleration and deceleration real-timely with computer. Using Microsoft Visual C＋＋ 6.0 development tools to design a PC monitoring software for automated processing. The hardware used a combination of ARM and FPGA, gave full play to the superior logic timing sequence function of FPGA and parallel processing advantage. The stepping motor subdivision control is used to improve injection precision, and the multiple sensors are applied to detect the state of the injection pump for successfully implementing the intelligent precision injection and the injector protection.
