Embodiment 1
[0061] figure 1 It is a flowchart of a method for establishing an indoor positioning database provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of establishing an indoor positioning database. This method can be implemented by the indoor positioning database establishing device in the embodiment of the present invention To execute, the device can be implemented in software and / or hardware, such as figure 1 As shown, the method specifically includes the following steps:
[0062] S110. Receive signal source identifiers and signal state information reported by each user equipment in a movement track.
[0063] Wherein, the user equipment may be a mobile phone, or a device such as a tablet computer that can usually move with the user and is capable of sending and receiving wireless signals, which is not limited in this embodiment, and the signal source is a device capable of transmitting wireless signals. Examples include WiFi hotspo...
Embodiment 2
[0100] figure 2 It is a flow chart of a method for establishing an indoor positioning database in Embodiment 2 of the present invention. This embodiment is optimized based on the above embodiment. In this embodiment, the signal source reported by each user equipment in the movement trajectory is received After the identification and signal status information of the user equipment, it also includes: identifying the moving state and moving distance of the user equipment; if the user equipment is in a non-walking state, or the moving distance is less than the first distance threshold, then discard the user equipment report The identification of the signal source and signal status information.
[0101] Thus, by restricting the moving state and moving distance of the user equipment, preliminary screening of the data reported by the user equipment can be realized, and the user equipment is in a non-walking state, or the data whose moving distance is less than the first distance thr...
Embodiment 3
[0113] image 3 It is a flow chart of a method for establishing an indoor positioning database in Embodiment 3 of the present invention. This embodiment is optimized based on the above embodiments. In this embodiment, according to the identification of the signal source and signal status information, The planar map of the target space and the moving distance of the user equipment, the establishment of the wireless signal network model and the training include: determining the geographic coverage of the initial wireless signal network model according to the planar map of the target space; State information, identifying the signal decay trajectory of the signal source; determining the center point in the signal decay trajectory as the preset anchor point, and determining the preset anchor point according to the markers in the target space; establishing each The association relationship between the anchor points is preset to form a wireless signal network model; the wireless sign...
