Abstract
The invention provides an intelligent optical cable with self-sensing function, belonging to the technical field of optical cables, comprising an optical cable, a sheath arranged on the surface of the optical cable, and a wrapping layer arranged outside the sheath, the sheath and the wrapping layer A monitoring module is arranged between them, and the monitoring module includes a sensor component, a microcontroller connected to the sensor component, a power supply and a display connected to the microcontroller. In the present invention, the optical cable itself is intelligently transformed, and the wrapping layer is embedded with intelligent sensors such as temperature, humidity, and smoke. At the same time, specific environmental parameters such as the length of the optical cable, ambient temperature, humidity, and smoke concentration can be intelligently displayed and transmitted. In this way, the operation and maintenance personnel can carry out convenient on-site monitoring and remote monitoring, discover environmental abnormalities in time, and eliminate defects in time, which solves the inconvenience caused by manual inspections.
Description
technical field [0001] The invention relates to the technical field of optical cables, in particular to an intelligent optical cable with self-sensing function. Background technique [0002] Optical fiber, referred to as optical fiber, is a light transmission tool that achieves the principle of total reflection of light in fibers made of glass or plastic. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. In the existing cities, suburbs or counties, the buried, overhead, or optical cables laid in concealed coverings will only be passively discovered and dealt with by the operation and maintenance personnel after the core is broken or broken, and the reason is often the location of the optical cable. The temperature of the space is too high or too low, the soil of the space is destroyed, and...
