程控IMU整机老化系统研究

Aging Table of Program-control IMU

在分析IMU整机老化系统的需求的基础上,划分了系统模块,采用计算机并口和ISA接口设计了IMU整机老化系统,其中并口用来实现多IMU同时老化,ISA接口实现IMU输出数据测量,而控制台程序实现IMU通道选择和数据记录。联机运行证明该老化系统工作稳定、可靠。

According to the demands of aging table of IMU that are analyzed in the paper, the modules are partitioned. The aging table of IMU is developed, in which the parallel port and ISA port of personal computer are employed at same time. The parallel port is used to connect several IMUs to personal computer, and the ISA port is applied to measure the output datum of IMU. Software is designed to select one IMU from several IMUs to measure, record and print. It also provides a Chinese interface to user. The aging table of IMU has already passed testing, and the results suggest that it can work stably and efficiently.
