摘要
目前设计的井下监测系统在受到外界干扰的状态下容易出现电压崩溃现象,数据丢失率难以达到用户要求。为此,基于NB-IoT无线远程通信技术设计了一种井下监测系统。监测系统的硬件包括控制模块、NB-IoT通信模块、传感器模块与井盖报警模块,同时使用液位传感器、压力传感器、甲烷传感器与三轴加速度传感器组成传感器模块,实现数据传感,再利用NB-IoT通信模块提高通信能力。由控制程序初始化、报警信息发送、实时定位与导航实现软件操作流程。实验结果表明,该文系统在受到外界干扰下,能够很好地控制电压波动,监控过程不会出现电压崩溃现象,当电压为0.48 V时,监测系统数据丢失率就可以达到0,保证井下监测效果。
The currently designed downhole monitoring system is prone to voltage collapse under the condition of external interference,and the data loss rate is difficult to meet user requirements.For this reason,a downhole monitoring system is designed based on NB-IoT wireless remote communication technology.The hardware of the monitoring system includes control module,NB-IoT communication module,sensor module and manhole cover alarm module.At the same time,the sensor module is composed of liquid level sensor,pressure sensor,methane sensor and three-axis acceleration sensor to realize data sensing,and then use NB-IoT communication module improves communication capability.The software operation process is realized by the initialization of the control program,the sending of alarm information,and the real-time positioning and navigation.The experimental results show that the system in this paper can well control voltage fluctuations under external interference,and there will be no voltage collapse in the monitoring process.When the voltage is 0.48 V,the data loss rate of the monitoring system can reach 0,ensuring the downhole monitoring effect.
