Design and Implementation of Wind Data Acquisition System Based on MX1601B-R

摘要:

为了满足MX1601B-R数采设备在风洞中进行数据采集的功能需求，基于MX1601B-R设计了一个风洞数据采集系统。本文首先从系统的结构组成以及工作原理对系统进行了分析。其次，对系统的数据采集硬件设备以及设计平台进行了概述。随后，详细的给出了本系统的设计思路，并从设备扫描连接、模块参数设置、零点显示、数据监控、数据采集以及数据查看与分析等方面对系统进行了模块化设计。最后，使用本系统对某风洞的温度排架进行数据采集与分析，并对系统进行功能验证。验证结果表明，本系统能够有效的对风洞吹风试验数据进行零点显示、数据监控、同步采集、多样化显示以及数据分析等，同时，系统的采集启动时间误差优于0.01s。由此，可以说明该系统界面简洁、功能齐全并且采集响应快，能够满足风洞吹风试验的数据采集需求。

Abstract:

In order to meet the functional requirements of MX1601B-R data acquisition equipment for data acquisition in wind tunnel, a wind tunnel data acquisition system was designed based on MX1601B-R. This paper firstly analyzes the system from its structure and working principle. Secondly, the hardware and the design platform of the system are summarized. Then, the design idea of the system is given in detail, and the modular design of the system is carried out from the aspects of equipment scanning connection, module parameter setting, zero point display, data monitoring, data collection and data viewing and analysis. Finally, the system is used to collect and analyze the data of the temperature rack in a wind tunnel, and to verify the function of the system. The verification results show that the system can effectively display, monitor, collect, display and analyze wind tunnel test data. Meanwhile, the start time error of the system is better than 0.01s. Thus, it can be explained that the system has simple interface, complete functions and quick collection response, which can meet the data collection requirements of wind tunnel test.
