摘　　要：微量注射泵是广泛应用于医疗、生物工程、基因工程、化学工程及环境工程等领域的一种数字化、智能化的精密仪器;为了提高微量注射泵的加注精度和加注效率,文章设计通过上位机及同步控制板可以同时控制多台精密微量注射泵工作;由上位机设置加注模式及工作参数,通过串口下载到多台注射泵,同步板控制多台注射泵同时精确加注;实验结果表明,每台注射泵的加注精度满足要求,系统抗干扰能力强,性能稳定,工作效率显著提高。Micro--injection pump is a digital, intelligent instrument widely used in such areas as medical, biological engineering, genetic engineering, chemical engineering, environmental engineering. In order to improve filling accuracy and efficiency of the micro-- injection pump, this design can control a plurality of injection pump simultaneously by epigynous computer and synchronous control board. Filling mode and working parameters are set by the epigynous computer, and then downloaded to every injection pump through the serial port, the synchronous board controls injection pumps to fill accurately and simultaneously. The experiment proved that filling precision of each injec- tion pump meet the requirements and the system has strong anti--interference ability and stable performance, the work efficiency of system is improved significantly.
