The invention discloses an information processing device, a positioning system, a control method and a readable storage medium, which can be positioned to a correct position. The device includes: a recording unit, an extraction unit and a positioning unit. The recording unit records radio wave intensities of short-range wireless communication between the plurality of first communication devices installed in the area targeted for positioning and the second communication device moving in the area for each time period. The extraction unit extracts a maximum radio wave intensity and radio wave intensities of other first communication devices around a position where the first communication device is installed, from the radio wave intensities recorded in the same time period. The positioning unit locates the position of the second communication device based on the plurality of radio wave intensities extracted by the extraction unit. Further, the positioning unit determines that the second communication device exists at the position where the first communication device with the radio wave strength is installed on the condition that the radio wave intensity extracted by the extraction unit is equal to or greater than a threshold value.
Description
[0001] This application claims that the Japanese application with the filing date of August 19, 2016 and the application number JP2016-161504 is the priority, and the content of the above application is cited, and the content of the priority is deemed to be fully described in this application. technical field [0002] The embodiments of the present invention relate to an information processing device, a positioning system, a control method and a readable storage medium. Background technique [0003] At present, a positioning system using a short-range wireless technology is known. Such a positioning system locates the position of a receiver that has received the annunciator code based on the annunciator code that identifies the annunciator transmitted from the annunciator and the radio wave strength of the transmitted annunciator code. In addition, the positioning system improves the accuracy of the receiver's position by performing positioning based on identification inform...
