介绍了一种体积小(180mm×120mm×100mm)、重量轻(2.0kg)、功耗低(10.8W)并适合于在空间应用的紫外可见光谱仪.同时提出一种将紫外可见光谱仪连接到空间生物舱总控器上的接口方案.利用该方案设计的接口电路,成功地将紫外可见光谱仪中的光谱数据传送到空间生物舱的总控器上,使得地面监控人员能够直观地看到紫外可见光谱仪的测量数据.介绍了紫外可见光谱仪与空间生物舱中总控器接口的通信协议和接口结构,通过RS232接口从光谱仪中获取光谱测量数据,通过CAN2.0B接口将光谱数据传送给空间生物舱的总控制器,进而给出系统测试结果.
A small size (180mm × 120mm × 100mm), light weight (2.0kg), low power consumption (10.8W) and suitable for the application in space UV visible spectrometer is introduced.At the same time the UV visible spectrometer is connected to the space Interface scheme on the main controller of the biological tank The interface circuit designed by this scheme was successfully used to transmit the spectral data of the UV-Vis spectrometer to the master controller of the space biological tank so as to enable the ground monitoring personnel to visually see the UV-visible The measurement data of the spectrometer is introduced.The communication protocol and interface structure of the interface of the UV-visible spectrometer and the total controller in the space biology cabin are introduced, the spectrum measurement data is obtained from the spectrometer through the RS232 interface, and the spectral data is transmitted to the space biology cabin through the CAN2.0B interface Of the total controller, and then give the system test results.
