基于STM32无线数据采集单元的设计

摘要

In monitoring and control systems, for the front-end parameter acquisition part design requirements, design a kind of multi-parameter acquisition unit which is based on STM32F030(using the ARM Cortex-M0 inner core), the unit can gather and store the temperature, humidity and atmospheric pressure data, it can realize the wireless transmission depending on NRF24L01. The unit include keys and LCD, which is easy to view the current parameter data. By choosing cost-effective digital sensors simplifies the circuit structure and reduce the hardware cost, and through rational software program design to further reduce the power consumption of the system. After testing the unit can work stably, and achieve the designing functions. The unit also has the advantage of be apt to transplant, it can be used in many fields, such as environment monitoring,industry data detection and intelligent control system.%针对监测控制系统中对前端参数采集部分的设计需求，设计了基于STM32F030（采用ARM Cortex－M0内核）处理器的多参数采集单元，采集单元可完成温湿度、气压等参数数据的采集和存储并通过无线模块NRF24L01实现数据的无线收发；单元配有按键及液晶显示器，便于查看当前参数数据。通过选取性价比高的数字传感器简化了电路结构并降低硬件成本，通过合理的软件程序设计进一步降低系统的功耗。经测试单元工作稳定，可实现参数的采集传输等功能。同时，采集单元方便移植，可应用于环境监测，工业数据检测，智能温室等监控系统中。
