Routing method and communication device for fire rescue network

Abstract

The invention provides a routing method for the fire fighting rescue network and a communication device. The routing method comprises steps that, to-be-transmitted fire fighting data is acquired through a wireless sensing element; a next base station type node and a node type which can receive the fire fighting data are determined, the node type is a fire fighting command vehicle, the node is taken as a target node, and a final routing path from the wireless sensing element to the target node is determined; if the node type is a relay base station, a routing path from the wireless sensing element to the node is recorded, a relay routing path from the node to the fire fighting command vehicle is acquired, and the fire fighting vehicle is taken as the target node to determine the final routing path; through the data transmission method based on a balancing network load, data transmission is carried out according to the final routing path. The communication device comprises the wireless sensing element and wireless coverage and relay equipment which are in mutual wireless communication. Through the method, the optimum routing capable of accomplishing data transmission can be searched among various nodes, and the method further has advantages of rapid transmission speed, high efficiency and high accuracy.

Description

technical field [0001] The invention relates to routing technology, in particular to a routing method and communication device for a fire rescue network. Background technique [0002] With the development of society and economy, the degree of urban modernization continues to increase, the structure of buildings at all levels is complex, and there are many types, the incidence of urban fires and other emergencies is increasing, and the requirements for the modernization and intelligence of fire rescue technology are also increasing. . [0003] The characteristics of fire rescue accidents are: First, the chain of disasters. Small disasters will cause chain disasters, leading to large-scale and major disaster accidents; second, on-site communication cannot be effectively guaranteed, because disasters lead to on-site chaos, communication lines and equipment may be damaged, so that fire rescue command work cannot be carried out smoothly, or The command lags behind; third, the s...

Problems solved by technology

[0005] When using wired communication technology for fire rescue data transmission, it is greatly affected by the environment, the network structure is not flexible enough, it is easy to cause resource waste and cost increase, the wiring is complicated, the communication line is easily damaged, and the maintenance cost of the communication line is high.

[0006] When wireless communication technology is used for fire rescue data transmission, the signal is seriously weakened due to the severe shielding of buildings with reinforced concrete as the main structure, and the signal interference in the environment makes it difficult to transmit to the fire command vehicle

The data to be transmitted includes on-site fire rescue personnel information (location, thermal imaging, heartbeat, etc.) and on-site conditions (smoke, temperature, video, and audio, etc.). WIFI technology and ZigBee technology are also subject to certain influences and restrictions in data transmission, resulting in the data not reaching the target location normally
