通用型无线数据监测模型设计

摘要

For the problem that most existing wireless data monitoring schemes are based on professional fields, have different data requirements, processing methods, safety standards, and high cost of development and application, the paper proposed a design scheme of universal wireless data monitoring model, and introduced overall design of the model and implementation of key technologies. The model uses STC89C52RC as master chip; adopts universal integrated wireless transmission module to transmit and receive data through radio frequency chip nRF24L01; bus module uses RS232 serial data communication method. The test results show that the power of data monitoring module of scene node and the regional dataset module are 8.58 mW and 29.7 mW, transceiver distance of the model is longer than 30 m, which is able to complete reliable and stable wireless data communication.%针对现有无线数据监测方案大多基于各专业领域,数据需求、处理方法和安全标准各异,开发应用成本较高等问题,提出了一种通用型无线数据监测模型设计方案,介绍了模型的总体设计及关键技术实现.该模型采用STC89C52RC作为主控芯片；采用通用集成型无线传输模块,通过射频芯片nRF24L01实现数据的发射和接收；总线模块采用RS232串口数据通信方式.测试结果显示,该模型中现场节点数据监测模块功率为8.58 mW,区域数据集中模块功率为29.7 mW,模型收发距离大于30 m,能够完成可靠、稳定的无线数据通信.
