Why OFS Early Warning Platform?Since the sensor head dos not have any active electrical components, it is intrinsically safe when used in the hazard environment such as coal mines ；OFS based monitoring network is capable to monitor the conditions of mine roof, electrical and mechanical equipments and detect rock burst, hazard gas, fire, flood, etc；OFS system addresses the constraints of multi-location and multi-parameter online monitoring issues;
1313
Advantages of OFS Early Warning Platform
Intrinsic Safety: data collection and transmission can be fully achieved through the fiber which is intrinsic safe; Multi location and multi parameter: The on-line remote monitoring at multi locations (over a few kilometers) and with multi parameters can be achieved with an optical fiber network. Multi-functional: one fiber-optic sensor may probe a variety of gases, such as CO, O2 and CH4 etc; Intelligent decision-making: the mine disaster is often caused by geology change, mining vibration, ventilation or support movement. By monitoring all these parameters in an integrated optic fiber intelligent sensor system, it is easier to identify the possible hazard before it occurred, hence enhance the disaster forecast through the early warning system.
