In addition, underground and building interior rescue workers are communicated with an external on-site command part by means of radio stations, and the underground and building interior conditions are complex, so that radio waves are shielded and interfered, the communication effect is poor and the communication is unstable. In order to ensure smooth communication, communication lines such as optical cables, communication cables and the like are paved, and under the application, a fire-fighting and life-saving illumination line with a communication function is urgently needed.
