摘　　要：单色仪是通过光栅的转动将不同波长的单色光从复色光中分离出来的重要光学仪器。本文对自动光栅单色仪嵌入式控制系统进行研究,根据光栅衍射理论及公式,提出单色仪的硬件系统和软件实现。在单色仪中使用USB接口来实现上下位机的通讯,下位单片机按照上位PC机的指令通过电机来控制光路系统并且采集信号,上位PC机对上传的采集信号数据进行分析处理。本研究课题已取得很好的经济效益。Concolorous apparatus is an inlportant optic apparatus, which can distinguish concolorous light from mulriple light by the running of grating. The realizafion of hardware and software of the concolorous apparatus is raised under the diffraction theory and formula, based on the research of the embedded control system of automatic grating concolorous apparatus. USB was used to reahze the communication of the upper computer and the single chip machine in concolorous apparatus. The hgbt-path system is coutrolled through the motor by the single chip machine under the order of the upper computer. Signals are also collected this way, and then are analyzed by the upper computer. This subject has been proved to be very economical.
