摘要: 针对传统中远距离通信系统的精度不高、传输数据不稳定、实时性差等缺点,文中提出了一种基于STM32单片机和RS485总线网络的无线中远程通信系统的方案。STM32低功耗、高性能,且接口丰富,适合便携式通信领域。利用STM32的标准通信接口实现了基于MODBUS协议的RS485总线和NRF24L01无线接收芯片的无线远程通信系统设计。经多次试验数据分析,系统传输出错率约为0.015,且系统的可靠性、稳定性均得到了大幅提升。

Abstract: The paper presents a wireless telecommunications system design based on the STM32 MCU and RS485 bus network to address the low accuracy,poor real-time performance and unstable data transmission of traditional telecommunication systems.The low-power high-performance STM32 offers rich interfaces for portable communications.The standard communication interfaces of STM32 are used to achieve a wireless telecommunications system based on the RS485 bus and the MODBUS protocol NRF24L01 wireless receiver chip.Experiments show that the error rate is about 0.015 with greatly improved reliability and stability.

Key words: STM32;communications systems;NRF24L01
