【摘要】：随着科技日益进步,无线测量系统被运用到各个领域。传统的有线测量因其通信距离有限、易受地理等环境影响,且需要在偏远的地区建设时成本太高等硬性短板而越来越不能满足日渐增长的远程传输需要,远程无线测量成为一个新的发展方向。它可以克服距离上的限制,能够实时采集、查看数据。本文利用已经成熟丰富的网络资源及高性价比的ARM Cortex-M3系列的一款芯片STM32F103,结合优秀的虚拟仪器集成环境软件LabVIEW,研究并设计了一种能够远程采集数据、实时查看数据的多参数无线测量系统,使得无线测量更加方便、快捷,对于无线测量领域在今后的研究与发展有一定的指导意义。本文基于STM32F103RCT主控芯片设计了一个多测量点无线测量系统。建立了由数据转换、控制模块(STM32F103RCT)、传输模块(SIM900A)以及总观测点组成的系统。数据转换模块主要利用STM32内部ADC进行数据转换,控制模块主要负责控制数据传输模块,数据传输模块主要负责通过GPRS无线传输把数据发送给接收终端并通过LabVIEW实时显示。根据无线测量系统的功能要求,设计了系统的硬件电路,并基于硬件电路设计了相应的软件程序,同时运用LabVIEW的G语言完成了多通道数据程序框图及前面板,并完成了系统的软硬件测试。测试结果表明,系统能够实现数据的准确无线传输,系统最终实现了数据在LabVIEW前面板上的实时直观监测,整个系统运行效果良好,达到了课题的设计要求。
[Abstract]:With the development of science and technology, wireless measurement system has been applied to various fields. Because of its limited communication distance, vulnerable to geographical and other environmental impacts, and the need to build in remote areas with too high cost and rigid boards, traditional wired measurements are becoming more and more unable to meet the growing demand for long-distance transmission. Remote wireless measurement has become a new direction of development. It can overcome the limitation of distance and can collect and view data in real time. In this paper, we study and design a kind of remote data acquisition based on the mature and abundant network resources and the high performance and price ratio ARM Cortex-M3 series chip STM32F103, combined with the excellent virtual instrument integration environment software LabVIEW,. Multi-parameter wireless measurement system, which can view the data in real time, makes wireless measurement more convenient and faster. It has some guiding significance for the future research and development of wireless measurement field. In this paper, a multi-point wireless measurement system based on STM32F103RCT master chip is designed. The system is composed of data conversion, control module (STM32F103RCT), transmission module (SIM900A) and general observation point. The data conversion module mainly uses the STM32 internal ADC to carry on the data conversion, the control module is mainly responsible for controlling the data transmission module, the data transmission module is mainly responsible for sending the data to the receiving terminal through the GPRS wireless transmission and displaying the data through LabVIEW in real time. According to the functional requirements of the wireless measurement system, the hardware circuit of the system is designed, and the corresponding software program is designed based on the hardware circuit. At the same time, the multi-channel data program block diagram and front panel are completed by using the G language of LabVIEW. The software and hardware of the system are tested. The test results show that the system can realize the accurate wireless transmission of data, the system finally realizes the real-time visual monitoring of the data on the front panel of LabVIEW, and the whole system runs well and meets the design requirements of the project.
