【摘要】：数据采集技术广泛应用于医疗、军工、遥感遥测等领域,传感技术和无线通信技术的进步更是推进了数据采集技术的发展。在飞行器的测量控制系统中的数据采集系统所采集的参量信息对飞行器的研制以及飞行试验至关重要,然而,随着飞行器的发展,数据采集系统需要采集的参量的种类和数量越来越多,而且感知这些参量信息的大量传感器分布于飞行器的各个位置,在这种条件下,传统的有线数据传输方式已不能满足要求,针对这一问题,本论文设计了基于WIFI的数据采集无线传输系统。设计的数据采集无线传输系统可用于采集分布于飞行器不同位置的传感器所感知的参量信息,并将数据无线传送至上游中心程序器以供后续数据处理。系统以无线传感器网络技术为基础、无线局域网技术为辅助实现数据的采集及无线传输;系统中的传感器节点以CC3200为主控芯片,获取传感器所感知的参量信息,并对参量数据进行数据编帧和无线发送。设计时为了验证数据在无线传输过程中的正确性,本系统利用PC机接收并分析数据。本文首先阐述了本课题的研究背景、意义以及相关领域的国内外研究现状和发展趋势,然后简单介绍了系统的相关理论基础,并在相关理论的基础上提出了数据采集无线传输系统的总体设计方案,而后在系统的组成结构、硬件电路、软件代码、测试等方面做了详细介绍。实验测试结果表明,设计的数据采集无线传输系统可实现对分布于被监测区域中的批量传感器所感知的参量信息的无线获取,数据在无线传输过程中不丢数;系统具有灵活性高、无线数据传输可靠性好、节省空间等特点,满足实际应用需求。
[Abstract]:Data acquisition technology is widely used in the fields of medical treatment, military industry, remote sensing and telemetry. The progress of sensor technology and wireless communication technology has promoted the development of data acquisition technology. The parameter information collected by the data acquisition system in the measurement and control system of the aircraft is very important to the development of the aircraft and the flight test. However, with the development of the aircraft, The data acquisition system needs to collect more and more kinds and numbers of parameters, and a large number of sensors that perceive the information of these parameters are distributed in every position of the aircraft. The traditional wired data transmission mode can not meet the requirement. In order to solve this problem, this paper designs a data acquisition wireless transmission system based on WIFI. The designed data acquisition wireless transmission system can be used to collect the parameter information perceived by sensors distributed in different positions of the aircraft and transmit the data wirelessly to the upstream central program for subsequent data processing. The system is based on wireless sensor network technology, WLAN technology is used to assist data acquisition and wireless transmission, sensor nodes in the system use CC3200 as the main control chip to obtain the parameter information perceived by the sensor. And the parameter data frame and wireless transmission. In order to verify the correctness of data in wireless transmission, the system uses PC to receive and analyze the data. This paper first describes the research background, significance, research status and development trends in related fields, and then briefly introduces the relevant theoretical basis of the system. On the basis of relevant theories, the overall design scheme of data acquisition wireless transmission system is put forward, and then the system structure, hardware circuit, software code, test and so on are introduced in detail. The experimental results show that the data acquisition wireless transmission system can realize the wireless acquisition of the parameter information perceived by the batch sensors distributed in the monitored area, and the data is not lost during the wireless transmission. The system has the characteristics of high flexibility, good reliability of wireless data transmission and space saving.
