摘要

为满足航天仪器对陀螺系统小型化的需求，设计了一种基于L3G4200D的三轴数字陀螺信号采集系统。C8051F040单片机作为本系统的核心控制器。微控制器通过I2C总线读取MEMS陀螺仪数据，然后通过RS232总线将数据传递给上位机进行处理。最后，对系统误差进行了分析。测试结果表明，该系统体积小、重量轻、可靠性高。这种仪器可以在太空中广泛使用。

Design of Gyroscope Signed Acquisition System in Space Instrument Based on L3G400D

To meet needs of Space instruments for gyro system miniaturization, we design a 3-axis digital gyro signal acquisition system, based on L3G4200D. C8051F040 micro controller acts as the core controller in this system. The micro controller reads the MEMS gyroscope data through the I2C bus, and then passes the data through the RS232 bus to the host computer for processing. Finally, this paper analyzed errors of the system. The test result shows that the system has a small size, light weight, high reliability. This instrument can be widely used in space.
