[0089] For ease of understanding, Figure 4 An example of a localization system applying a pressure-sensing-based indoor occupant marker localization algorithm is given. In the figure, C is the central node, and I, J, K, L, M, and N are indoor positioning nodes.
[0090] Such as figure 1 As shown, the specific implementation steps of the indoor personnel marker positioning algorithm based on pressure perception in this embodiment are as follows:
[0091] Step S1: The indoor positioning system detects whether there is a person in the room according to the current person list record in the room; if there is, go to step S9, otherwise go to step S2.
[0092] Step S2: All the positioning nodes in the room enter the sleep mode, and the nodes perform pressure signal reset processing according to the current collected values of the pressure sensors.
[0093] In this embodiment, since the positioning function is not enabled in the current step, the pressure coordinates obtained by...
