摘要
为实现对多个实验室环境的实时监测、自动警报、自动记录等功能,设计了一种多实验室环境无线监测系统,介绍了系统的工作模块、软件工作流程、无线通讯策略及上位机监测系统。系统由STC89C52、DHT22温湿度传感器、nRF24L01+构成环境监测节点,由STC12C5A6、nRF24L01+、SD存储卡、LCD12864构成环境监测终端,通过串口连接到基于LabVIEW的上位机数据库系统。实际应用表明,该系统能实时采集、显示、记录多实验室环境数据,具有可靠性好、操作方便等特点。
In order to realize the functions of real time monitoring environment, automatic warning and automatic recording, this paper proposed a wireless monitoring system for multi-experimental environment. It described the operating model, software working flow, wireless communicate strategy and the monitoring system on PC. The STC89C52, temperature and humidity sensor DHT22, and nRF24L01＋ were included in the environment monitoring node. The monitoring terminal includes STC12C5A6, nRF24L01＋, SD storage and LCD12864, and connected to the computer database system via serial port. It proved that the system could acquisition, show and record multi-experimental environment data in real time. And it＇s reliable and easy to use.
