摘要
为了促进对燃气井的统一检测管理,确保井中燃气管道的安全以及减少管道日常检查中人力物力的消耗,设计了一种基于窄带物联网的低功耗燃气井实时监测系统。该系统实现了对燃气井中泄漏的可燃气体浓度、温湿度、井盖状态的实时监测,利用NB-IoT技术将检测到的信息无线传输到云端平台,以及将相关数据集中存储管理,并在应用端实时显示。由于燃气井中的工作环境比较恶劣,温湿度变化对可燃气体传感器正常工作会产生干扰,因此系统采取了一种校正方法来补偿环境因素对可燃气体传感器测量结果的影响。实验结果表明该系统具有低功耗、使用寿命长、运行稳定等特点,实现了对燃气井中泄漏的可燃气体浓度等数据的实时监测。
In order to promote the unified detection and management of gas wells,ensure the safety of the gas pipeline in the well and reduce the consumption of manpower and material resources in the daily inspection,a low power consumption gas well real⁃time monitoring system was designed based on narrowband Internet of Things.The system realized the real⁃time monitoring of combustible gas leakage concentration,temperature,humidity and well covers status,and transmitted the detected information to the cloud platform wirelessly by NB-IOT technology,as well as centralized storage of relevant data,and real⁃time display on the application side.Due to the bad working environment in gas well,the change of temperature and humidity can cause interference to the normal operation of combustible gas sensor,the system adopted a correction method to compensate the influence of environ⁃mental factors on the measurement results of combustible gas sensor.The experimental results show that the system has the charac⁃teristics of low power consumption,long service life and stable operation,realizing the real⁃time monitoring of combustible gas leakage concentration in gas wells.
