| Abstract: | We developed an optical fiber sensing technology based gas drainage pipeline human body safety monitoring system with spectrum absorption and fiber Bragg grating technology. The system can perform realtime monitoring for such key parameters within the pipe as methane, oxygen, temperature and pressure. The system can also compensate methane concentration based on temperature and pressure, measurement accuracy improvement of 7% and 11% after compensation. Scenario experimental results show that the system can achieve safety monitoring for gas drainage pipeline. |
