Electronic interface of a mini-type ultraviolet-visible spectrometer

A kind of Ultraviolet and Visible Light Optical Spectrum Instrument (UVLOSI) is introduced. This facility is characterized with light weight, small volume and low power consumption, which is suitable to be utilized in space. Meanwhile, an interface scheme for connecting the UVLOSI with space biologic capsule control system is presented. Following this scheme, an interface circuit is designed, and the data of the UVLOSI is successfully transferred to the center controller in space biologic capsule. Using this method, the measurement data of the UVLOSI in the system control panel can be directly observed. The interface communication protocol (RS232) between the UVLOSI and the interface circuit is presented. After that, the interface communication protocol (CAN2.0B) between space biologic capsule control system and the interface circuit is described. At last, measurement results of the UVLOSI are given.
