[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.
