MOBILE COMMUNICATION TERMINAL, MANAGEMENT SYSTEM, AND MANAGEMENT METHOD

Title:

MOBILE COMMUNICATION TERMINAL, MANAGEMENT SYSTEM, AND MANAGEMENT METHOD

Document Type and Number:

Japanese Patent JP2017151030

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a management system and a management method capable of improving detection accuracy of the position of a vehicle or a worker.SOLUTION: In a management system 10, the radio wave intensity of a radio access point 100 is detected by a radio wave intensity detection part 303 of a mobile communication terminal 300 mounted on a vehicle 30, and a position P1 of the mobile communication terminal 300 is detected on the basis of the radio wave intensity by a position detection part 304. An acceleration is detected by an acceleration detection part 401 of a mobile communication terminal 400 carried by a worker 40, and an azimuth is detected by an azimuth detection part 402, and the radio wave intensity of the radio access point 100 is detected by a radio wave intensity detection part 403, and a position P2 of the mobile communication terminal 400 is detected on the basis of the acceleration, azimuth and radio wave intensity by a position calculation part 404.SELECTED DRAWING: Figure 1
