摘　　要：针对传统CT教学实验仪使用不便与技术落后的现状,开发了以P89V51RD2单片机为核心完成数据采集、运动控制及USB通信等功能的新一代增强型CT教学实验仪。该仪器除具有完善的CT功能外,还能完成四个相关的辐射物理实验。讨论了仪器的设计与实现方法,给出了其主要硬件电路和软件结构。实际应用表明,该仪器在性价比、使用方便性和可靠性等方面均有明显优势。Conventional CT teaching experimental instrument is used inconveniently, and its design technique is behindhand. A new generation CT teaching experimental instrument is developed using P89V51RD2 microcontroller to accomplish data acquisition, motion control and USB communication. As an enhanced type, the instrument not only has primary CT function and high quality image, but also can help to do four related radiation experiments. It discusses the method of design and implementation of the instrument, and gives out its main hardware circuit and software structure. Practical applications show that it is more stable in performance, lower in cost, more convenient in use and higher in dependability.
