Location beacon and fire protection internet of things location system

Abstract

The invention discloses a location beacon and a fire protection internet of things location system. The location beacon is arranged in the position of a fire protection facility and comprises an MCU, a working status indication unit, a communication unit, an RFID unit, a self-checking unit, an environment parameter detection unit and a power supply unit, wherein the working status indication unit, the communication unit, the RFID unit, the self-checking unit, the environment parameter detection unit and the power supply unit are connected with the MCU. The fire protection internet of things location system comprises a fire protection management center, a central management mainframe, a data concentrator, a plurality of individual soldier mobile location terminals and a plurality of the location beacons, wherein the location beacons exchange data with the individual soldier mobile location terminals through the RFID unit, the individual solider mobile location terminals are in communication with the central management mainframe through a network, the communication unit of each location beacon is connected with the central management mainframe through the network and the data concentrator, and the central management mainframe is in remote communication with the fire protection management center through the network. When the location beacons are used in the fire protection network of things system, accurate fire protection facility location information and real-time location information of firemen who are conducting rescuing can be provided.

Description

technical field [0001] The invention belongs to the field of fire-fighting internet of things systems, and in particular relates to a positioning beacon and a fire-fighting internet of things positioning system with the positioning beacon. Background technique [0002] At the scene of fire rescue and rescue, if the firefighters in the fire scene cannot know the exact location of the fire-fighting facilities in time, the rescue work will be delayed, which will easily cause more property losses, and at the same time, the lives of the people to be rescued will be more likely to be endangered. ; If the firefighters cannot keep abreast of their location and the environmental conditions at the location, the situation of the firefighters will not be able to be grasped by other team members and the rescue command center (namely the fire management center) in time, and it is easy to get lost in the fire scene and be in danger. Sometimes, it is difficult to carry out follow-up res...

AI Technical Summary

Problems solved by technology

The system does not specifically involve how to obtain the information needed for fire management and rescue (such as information on fire facilities and personnel), nor does it involve positioning functions and technologies

In addition, there are some positioning solutions, but they are not suitable for the fire-fighting Internet of Things system. For example, the communication signaling of the GSM base station is used for positioning. It can be positioned indoors and outdoors, but the positioning accuracy is generally about 500 meters, and the position deviation is large. ; With the help of the global positioning system (such as GPS) for positioning, the positioning accuracy is about 10 meters, which can barely meet the positioning requirements, but it cannot be positioned within the building, and the inertial positioning algorithm of the global positioning system is used to provide the calculated positioning information, can only accurately calculate the position within a few seconds, the time is a little longer, and the effect is not good; the scheme of assisting positioning with the help of an electronic compass or a mobile 3D gyroscope has a slightly higher accuracy, but requires periodic calculations to update the positioning information , the reliability is not high
