Abstract

The invention discloses an emergency evacuation guiding system based on UWB. According to the system, an emergency indicating lamp is internally provided with a power line carrier module, the power line carrier module is connected with a power line carrier communication terminal through a carrier signal, the power line carrier module is connected with a UWB base station through a wireless network signal, and the UWB base station is connected with a UWB positioner through a ranging signal. On the basis of an original electrical circuit, the UWB base station based on the UWB technology is used, and the power carrier communication terminal is connected through the power carrier signal, so that the wireless networking function and the real-time communication function of an evacuation indicating lamp are realized, so that an escaper can rapidly, orderly and safely evacuate by carrying the UWB positioner according to a guide route sent by a fire control center and a direction displayed by an emergency evacuation lamp, the escaper is prevented from escaping to a wrong fire source dangerous area, the possibility of losing communication is avoided, and the life safety of people is guaranteed.

Description

technical field [0001] The invention belongs to the field of public security, and in particular relates to a guidance system applied to indoor emergency evacuation. Background technique [0002] When a fire breaks out, the indoor escape personnel will escape according to the direction guidance of the fire evacuation indicator light. In buildings and shopping malls, the evacuation guidance system is an essential fire-fighting facility, which includes a fire control center, evacuation indicator lights and communication signal equipment. [0003] Among them, the evacuation indicator light is generally composed of a lighting control circuit board (composed of voltage transformation, charging, LED control, etc.), a light guide plate, a glass plate, and the like. There are mainly two types of evacuation indicator lights at this stage: [0004] 1. Traditional evacuation indicator light: adopts centralized AC220V power supply, and keeps always on when there is no fire at ordinary ...
