“…Domestic scholars have carried out risk assessment of cable tunnel. Ding conducted a basic study on the initial model of cable tunnel fire and established a heat transfer model at the initial stage of fire, which can predict the temperature distribution characteristics in different fire scenarios 4 . Zhang proposed a fire safety evaluation index system suitable for urban power cable tunnel, and first used the analytic hierarchy process to evaluate the fire safety of an urban cable tunnel 5 .…”

Laying power cables in existing tunnels can not only save land resources, but also improve the utilization rate of urban space. At the same time, it also has important practical significance for expanding the construction and development space of urban power grid. Therefore, in order to assess the safety risk level of cables laid in the built tunnels, the safety risk assessment index system of laying cables using existing tunnels is established, which contains 19 evaluation indexes, involving 8 sub-systems such as cable tunnel structure, lighting system and power supply system. Finally, the fuzzy analytic hierarchy process (AHP) method is employed to evaluate the safety risk of a power cable laying project in an existing tunnel. The results show that the risk level of laying cable trench in the built tunnel is low, and the feasibility of laying power cable in the built underground traffic tunnel is also proved.

“…Thus, to control and extinguish fire hazards, many types of firefighting equipment have emerged. In the current building fire protection design, fire detections, such as gas or smoke and temperature sensors [1], and fire extinguishing methods, such as automatic sprinkler systems, are commonly adopted [2,3]. Video-based technology or computer vision methods are also used in some firefighting system [4].…”

In view of the many problems in firefighting robots, such as complicated flame positioning, poor environmental adaptability, and difficult installation and debugging, a new firefighting robot design is presented with video full closed-loop feedback to extinguish ground fire in this paper. The firefighting robot consists of a 2-DOF robot, a monocular camera, and a controller. The monocular camera installed on the second link of the robot is utilized to detect and locate ground flames. The robot can dynamically adjust the water landing point to track a flame in real-time through motion control, as the camera is specifically designed with an additional infrared narrowband pass filter and a filter-switching mechanism. An algorithm of detecting and positioning for flame and water landing point is proposed based on image processing and robotic kinematics. Experimental results show that the firefighting robot with video full closed-loop feedback can realize real-time flame detection, location, and sprinkler, and can dynamically track fire location within the monitoring scope. The distance error between fire and the landing point of the water jet can be controlled within a narrow range. Moreover, this firefighting robot is easy to install, debug and have good environment adaptability, and provides efficient and safe solutions for complicated firefighting environment. At the same time, due to its small size and convenient calibration features, this firefighting robot is especially suitable for large space environments.
