Problems solved by technology

This kind of network space positioning technology needs to arrange a large number of network nodes indoors in advance, which is costly and easily affected by the environment. In the event of a fire, the temperature generated by the flame can easily damage the network nodes, thus affecting rescue work.

Embodiment 1

[0041] Please refer to figure 1 Shown, a kind of floor discriminating method, it comprises the following steps:

[0042] 110. Receive trajectory data of an inertial navigator and altitude data of a barometer, where the inertial navigator and the barometer are located at the same location.

[0043] The trajectory data output by the inertial navigator is a point set formed by X, Y, and Z coordinates, and the barometer can output the altitude data of a certain point, that is, the ordinate data. The co-location of the inertial navigator and the barometer means that both are on the same firefighter. Both the inertial navigator and the barometer use fire-fighting special equipment. These devices are not easily affected by the external temperature environment, and are small in size and can be carried by firefighters. The inertial navigator is a rectangular cube, the size of a mobile phone lithium battery, embedded in the design Good special insoles will not cause any additional bur...

Embodiment 2

[0063] Embodiment 2 discloses a floor discrimination device corresponding to the above embodiment, which is the virtual device structure of the above embodiment, please refer to Figure 4 shown, including:

[0064] The receiving module 210 is used to receive the trajectory data of the inertial navigator and the altitude data of the barometer, and the inertial navigator and the barometer are located at the same position;

[0065] A replacement module 220, configured to replace the ordinate in the trajectory data with the altitude data, and define the replaced trajectory data as a running trajectory diagram;

[0066] An acquisition module 230, configured to acquire an inflection point of a floor according to the running track diagram;

[0067] The determining module 240 is configured to determine the position of the target floor according to the initial floor and the number of inflection points.

[0068] Further, both the inertial navigator and the barometer are located on the...

Embodiment 3

[0073] Figure 5 A schematic structural diagram of an electronic device provided in Embodiment 3 of the present invention, such as Figure 5 As shown, the electronic device includes a processor 310, a memory 320, an input device 330, and an output device 340; the number of processors 310 in a computer device may be one or more, Figure 5 Take a processor 310 as an example; the processor 310, memory 320, input device 330 and output device 340 in the electronic device can be connected by bus or other methods, Figure 5 Take connection via bus as an example.

[0074] Memory 320, as a computer-readable storage medium, can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the floor discrimination method in the embodiment of the present invention (for example, the receiving module in the floor discrimination device 210, replacement module 220, acquisition module 230 and determination module 240). Th...

Abstract

The invention discloses a floor judging method, which comprises the following steps: receiving trajectory data of an inertial navigator and altitude data of a barometer, wherein the inertial navigatorand the barometer are positioned at the same position; replacing the longitudinal coordinate in the trajectory data with the altitude data, and defining the replaced trajectory data as a running trajectory chart; obtaining the inflection point of a floor according to the running trajectory chart; and determining the position of a target floor according to an initial floor and the number of the inflection points. The invention also discloses a floor judging device, electronic equipment and a storage medium. According to the invention, firefighters can complete accurate judgment of the floors where the firefighters are located only by the inertial navigator and the barometer, and the floor judging device is simple in structure and convenient to carry.

Description

technical field [0001] The invention relates to the field of fire safety, in particular to a floor discrimination method, device, electronic equipment and storage medium. Background technique [0002] When a fire breaks out in a high-rise building, due to the criss-crossing of various pipelines and lines, the fire smoke will spread rapidly and the firefighters' vision will be limited when participating in the rescue. Once the firefighters get into trouble, the rescue location will be unclear, which will delay the rescue work and cause firefighters Life is threatened, so an algorithm that can locate firefighters on the floor is urgently needed. The existing indoor positioning technology is mainly to build a network topology indoors, and find the nearest network node according to the location of the person, and the location of the node is equivalent to the location of the person. This kind of network space positioning technology needs to arrange a large number of network node...
