航天包装箱用便携式数据采集仪的实现

Implementation of the Portable Data Collector for Aerospace Packaging Boxes

针对目前航天器储运包装箱的实际需求,以ARM9处理器与嵌入式Linux操作系统为基础,设计开发了一款便携式数据采集记录设备。给出了系统的整体设计方案、结构框图、模数转换硬件电路以及基于Linux操作系统下模数转换芯片的驱动程序设计。整个系统硬件体积小、功耗低、运行稳定、携带便利。试验表明,系统满足航天储运包装箱提出的多通道实时数据采集、记录、传输、处理及显示等功能。

In accordance with the actual demands for aerospace storage and transportation boxes,with ARM9 processor and embedded Linux operating system as the basis,the portable data collecting and logging device has been developed. The overall design scheme,structural block diagram,hardware circuit of A / D conversion and the design of driver program for A / D conversion chip under Linux operating system of the system are given. The system hardware features compact,low power consumption,stable operation,and easy to carry. The tests show that the system satisfies the functions of multi-channel online real time data collection,record,transmission,processing and display that are requested for aerospace storage and transportation boxes.
