摘要
因基于蓝牙和WIFI技术的监测网方案具有通信距离短、抗干扰差的缺点,提出了一种基于LoRa和蓝牙的智慧医院监测网方案;该方案以各类蓝牙无线传感器、蓝牙模块、LoRa模块、无线传感设备、数据中继器、LoRa网关为核心,采用星型结构,建立了兼顾多种采集和监测需求的监测网。介绍了系统整体组成结构、LoRa无线传感设备和数据中继器软硬件设计,实现了医院中相关数据的采集和监测,最后测试了系统的功能和性能;测试结果表明该方案具有通信距离长、抗干扰能力强的特点。
Because the monitoring network scheme based on Bluetooth and WIFI technology has the shortcomings of short communication distance and poor anti-interference, a scheme of intelligent hospital monitoring network based on LoRa and Bluetooth is proposed. The core of the scheme is various Bluetooth wireless sensors, Bluetooth modules, LoRa modules, wireless sensor devices, data repeaters and LoRa gateways.The monitoring network is designed with star network, which is compatible with various collecting and monitoring requirements. The overall structure of the system, the software and hardware design of LoRa wireless sensor equipment and data relay are introduced. Acquisition and monitoring of relevant data in hospitals are realized. Finally, the function and performance of the system are tested. The test results show that the scheme has the characteristics of long communication distance and strong anti-interference ability.
