Embodiment Construction

[0014] Such as figure 1 As shown, the indoor real-time positioning system of the mobile terminal includes various position sensors, position reference nodes, mobile terminals, a main control server and a display terminal. First, the mobile terminal will determine its approximate position in the area by collecting the surrounding location reference nodes, and use this as the initial coordinates of the mobile terminal, and then the mobile terminal will collect data from sensors such as acceleration sensors, direction sensors, gravity sensors, and electronic compass , used to determine the user's posture, movement direction and movement mode and other information, and at the same time transmit the obtained data to the main control server, the main control server will filter, match and store the data sent by the mobile terminal, and finally The current movement status and position coordinates of the positioning personnel are transmitted to the display terminal for display in real ...

Abstract

The invention relates to a real-time locating system, in particular to an indoor real-time locating system of a mobile terminal. A mobile terminal is firstly used for collecting data of sensors including data of an acceleration sensor, a directional sensor, a gravity sensor and an electronic compass, the position changing information of the mobile terminal is finally determined by comprehensively processing the data collected by the sensors, and then an initial position and comprehensive reference for a subsequent position are determined through the position information data transmitted by received position reference nodes. The data after being processed is transmitted to a main controller, after the received data is filtered and matched by the main controller, the specific position information of the mobile terminal is displayed on a display terminal.

Description

technical field [0001] The invention relates to the fields of wireless communication and RFID real-time positioning, in particular to an indoor real-time positioning system for mobile terminals Background technique [0002] With the development of hardware technology, mobile smart terminals integrate a wealth of location information sensors, such as GPS receivers, acceleration sensors, and gyroscopes. On the other hand, smart mobile terminals have integrated various wireless communication devices, such as wireless cellular network (2G / 3G), wireless local area network (WLAN), and Bluetooth (Bluetooth). With the development of near-field communication technology NFC, mobile smart terminals will also integrate Near Field Communication (NFC) communication devices. With the NFC communication module, the smart terminal can act as RFID and has the function of being able to read RFID. [0003] With abundant position sensors and radio frequency modules, mobile smart terminals can u...
