高原型航空地面电源数据采集系统设计

摘要

为了采集航空地面电源在高原环境下的运行状态参数,给出了一种基于S3C2440的高原型地面电源数据采集系统硬件和软件设计方案.系统通过应用S3C2440处理器控制多路模拟开关,利用分时复用技术将地面电源多路传感器数据送入数据采集卡.将所获得的数据存储到可移动存储设备中.为了方便用户与系统之间的交互,还提供了生成报表、存档、打印输出等功能.系统分析软件能够直观地观察特征参数的详细情况,通过编程实现对实验结果数据的复现,运行曲线显示、数据表格显示.%To acquire operating state data of ground power supply for aviation in plateau environment,this paper gave a design scheme of data acquisition system for plateau ground power supply of hardware and softwarc based on S3C2440.The system processes data with S3C2440 to control multi-channel analog switches and time division multiplex access to transmit data of multi-channel sensors of ground power supply into data acquisition card.Acquired data can be stored on portable storage device.To facilitate the interaction between user and system,it also provides many functions,such as report generation,archiving,print output,etc.System analysis software can make the details of the characteristic parameters be observed directly by reproducing the data of the experimental results,displaying the running curves and showing data tables.
