摘　　要：介绍了一种利用光电倍增管作为探测器的光栅扫描式单通道分光测色仪的单片机电路设计和利用C语言程序直接对串口芯片的寄存器进行读取操作的数据采集技术。给出了仪器中的下位机(8051单片机)和上位机(PC机)的软件设计思想。实验测得的结果证实了该仪器具有很高的测量精度。The construction and function of the correlative circuit, the data collection technology to read data directly from register in COM by using C language for one type of single-channel spectrophotometer, which has a grating scanner and uses a photomultiplier as detector, are detailed. The program flow diagram on single-chip and personal computer is provided. The experiment results show that the instrument is qualified for color measuring.
