多单片机在放射性试剂分装仪中的应用

Application of Multi-singlechip Based on Radioative Reagent Diluting and Dividing System

放射性试剂分装仪通过液晶显示器和键盘实现人机交互,5个高精度的步进电机实现吸液臂的三维定位和大小针筒吸液量的控制。在整个分装系统中共用到了6片单片机,所有单片机通过串行口连接成一个相互协作的系统,实现了医用放射性试剂的高精度、零污染分装和稀释。

The radioactive reagent diluting and dividing system exchanges information with human by using LCD screen and keyboard. Five high precision step-motors are used to make the mechanical arm with two injectors moving to three-dimentional location, and control the inhaleation volume of the two injectors. There are six singlechips in this system. All of the singlechips are united to a cooperative system by serial-bus. Thie system can be used to divide and dilute the radioactive reagent with high precision and no contamination.
