Description

Technical Field

[0001] The utility model relates to the technical field of evacuation signs, and in particular to an intelligent tunnel induction evacuation sign. Background Art

[0002] Tunnels are an important part of modern transportation construction. Their closedness and restrictions make escape and evacuation particularly critical in emergency situations, such as fires or traffic accidents. Tunnel induced evacuation signs are safety facilities that came into being in this context. These signs clearly indicate the exit locations, safety facilities and safe areas in the form of graphics, text or symbols, providing clear and direct escape guidance for people in the tunnel. In thick smoke and harsh environments, tunnel induced evacuation signs can quickly guide people to find safe exits and escape routes, greatly improving evacuation efficiency and reducing confusion and stampede accidents. In addition, these signs can also reduce people's panic in emergency situations, help them make correct decisions, and ensure their lives. Therefore, tunnel induced evacuation signs occupy a pivotal position in the tunnel safety management system and are an indispensable part of ensuring the safe evacuation of personnel.

[0003] The design of tunnel evacuation signs follows scientific principles to ensure effectiveness and reliability. Simple and clear symbols, graphics and text are used to ensure that people can understand them quickly. Bright colors, reflective materials and appropriate lighting ensure that they can be clearly identified under various conditions.

[0004] Patent document CN218116209U discloses a tunnel guide sign with both sight guidance and emergency guidance, which is composed of several guide sign units connected along the length direction of the tunnel. The guide sign unit includes a sight guidance plate and an emergency guidance plate. The sight guidance plate and the emergency guidance plate are vertically connected. The sight guidance plate and the emergency guidance plate are respectively covered and installed on the facade and plane of the tunnel inspection road. The sight guidance plate is a plate with a sight guidance mark on the surface, and the emergency guidance plate is a plate with an emergency guidance mark on the surface; the emergency guidance plate of the guide sign is set on the plane of the tunnel inspection road. When people are evacuated in an emergency, it not only plays an emergency guidance function, but also can play a lighting function under the feet of people, thereby improving the evacuation efficiency of people. Several guide sign units of the tunnel guide sign are connected along the length direction of the tunnel, and the continuity of emergency information is good. The sight guidance mark and the emergency guidance mark are combined through the tunnel guide sign to reduce the installation workload.

[0005] As in the prior art of the above patent, the above guidance signs are usually set perpendicular to the side wall of the tunnel, but on curved sections, in order to ensure that drivers can clearly see and understand the guidance signs, they need to be installed at a specific angle. Moreover, even if the appropriate installation angle is determined, the actual installation process of the guidance signs is quite complicated. The internal environment of the tunnel is often limited and special, and the installation requirements are highly precise. Every step from measurement, positioning to fixed installation requires high professional skills and rigorous operating procedures. Utility Model Content
