Description

Net-free self-positioning emergency help-seeking relay type bidirectional intelligent emergency indication device and control method Technical Field The invention relates to the technical fields of fire emergency lighting, intelligent evacuation indication, wireless emergency communication and disaster environment detection, in particular to an emergency device and a control method which are independent of an external network and a satellite positioning system, can realize netless self-positioning, relay forwarding of distress signals and bidirectional double-color synchronous guiding, and are suitable for whole-scene emergency escape and personnel search and rescue in building, underground garages, tunnels, mines, field scenic spots and the like. Background In the field of fire emergency lighting and intelligent evacuation indication, the prior art has the following core defects: 1. The system has the advantage of single function, the existing system can only provide unidirectional escape guidance, and can not synchronously guide rescue workers to locate trapped people, so that evacuation and rescue route conflicts frequently occur. For example, in a fire scenario, evacuees and rescue workers may delay rescue opportunities due to the crossing of paths. 2. Network dependence the prior art is highly dependent on external networks and satellite positioning systems. When a disaster occurs, the base station and the network equipment are easy to break down, and the satellite signals are not available in indoor, underground and other scenes, so that the whole system is invalid. 3. The signal transmission limitation is that the distributed relay capability is lacking, the distress signal of the trapped person cannot be effectively transmitted in a netless environment, and the rescue personnel are difficult to accurately position. For example, in mine accidents, traditional help-seeking devices have limited rescue coverage due to signal attenuation. 4. The traditional intelligent evacuation system needs professional manual addressing, networking and debugging, the debugging period of a large project is as long as several days, and the labor cost is extremely high. For example, large-scale commercial complex evacuation system debugging requires a lot of manpower and material resources. 5. The detection and guide separation is that the prior art can not realize the accurate positioning of disaster points and the dynamic linkage of evacuation routes, and is easy to mislead people to enter dangerous areas. For example, after an earthquake, the building partially collapses, and the conventional system cannot update the safety path in real time. The prior art can not form a complete life safety link of self-positioning networking, disaster detection and early warning, dynamic escape guiding, help seeking positioning relay and global situation sensing, and has serious safety dead zones. Disclosure of Invention Technical problem to be solved The invention aims to overcome all defects of the prior art, and provides an emergency indicating device and a control method which do not need a network, satellite positioning, pairing, zero debugging and full scene adaptation, so that self-positioning networking, disaster accurate positioning reporting, SOS distress signal relay forwarding, escape and rescue bidirectional synchronous guiding under a non-network environment are realized, and meanwhile, the dual purposes of daily route guiding and emergency rescue and disaster relief are realized. Technical proposal The core technical scheme of the invention is divided into a method side and a device side: Method side (corresponding claims 1-4) 1.

The technology does not need an external network or satellite signals, has the positioning accuracy of 0.5 meter, and is suitable for complex environments. 2. And in the distributed chain relay technology, distress signals are transmitted to rescue workers or external receiving equipment step by step from the positions of trapped workers through relay transmission among devices. Each device can be used as a relay node to expand the signal coverage range and solve the signal transmission difficulty in the networking environment. 3. The two-way double-color synchronous guiding technology adopts an independently controlled escape guiding lamp set (green) and a rescue guiding lamp set (red) to realize two-way synchronous guiding of escape and rescue. The escape personnel can escape along with the green light, and the rescue personnel can position the trapped personnel through the red light, so that the route collision is avoided. Device side 1.
