摘要:
为了解决有线通讯在遥控遥测、小区传呼、工业数据采集、无线遥控系统等领域中受到的制约,本文提出了基于STM32F103单片机控制nRF2401射频芯片的高速数据无线传输方案。本方案以STM32单片机为核心,采用nRF2401射频芯片,构建一种稳定可靠的无线通讯方案;同时,在监测端模块配有控制器局域网络(controller area network,CAN)、RS485以及串口通讯(serial communication)3种通信方式,而且在PC端通过通用串行总线(universal serial bus,USB)可实现即插即用、热拔插以及点对点无线传输功能,并通过串口助手工具进行测试。测试结果表明,传输速率最高可达到1 Mbit/s,在空旷场地内,保证有效距离在100米以上,且传输准确无误,说明该设计可以实现可靠稳定的无线传输,且传输速率高。该研究有效解决了有线通讯存在的弊端,与传统无线传输相比提高了传输速率和距离,增强了传输的可靠性和稳定性。
Abstract:
In order to solve the restriction of wired communication in the fields of remote control telemetry, cell paging, industrial data acquisition and wireless remote control system, this paper presents a high-speed data wireless transmission scheme based on stm32f103 single chip microcomputer to control nRF2401 RF chip. This scheme takes STM32 single chip microcomputer as the core, uses nRF2401 RF chip to construct a stable and reliable wireless communication scheme, at the same time, the monitoring end module is equipped with controller local area network (Controller region Network,can), RS485 and serial communication (serial Communication) 3 modes of communication, as well as plug-and-play, hot-swappable, and Point-to-point wireless transmission via universal Serial bus at the PC end, and are tested with serial assistant tools. The test results show that the transmission rate can reach up to 1mbit/s, in the open field, to ensure the effective distance of more than 100 meters, and the transmission is accurate, which shows that the design can achieve reliable and stable wireless transmission, and the transmission rate is high. This research effectively solves the drawbacks of wired communication, improves the transmission rate and distance compared with the traditional wireless transmission, and enhances the reliability and stability of the transmission.
