Problems solved by technology

[0004] The traditional positioning system mainly has the following problems: when the mobile terminal is subject to strong electromagnetic interference, the communication system fails; in the environment where the GPS signal is weak, accurate position information cannot be obtained, and the positioning error is too large; in the case of no GPS signal , there is no other means to obtain its own location information; it can be seen that the positioning of the mobile terminal in the prior art is strongly dependent on the GPS signal, and the positioning error is relatively large

Abstract

The invention relates to a wireless positioning system and method based on multiple mobile terminals. The positioning system comprises a server, a positioning algorithm processing module, a database module and a plurality of mobile terminals provided with communication modules; the plurality of mobile terminals provided with the communication modules form a network, and each mobile terminal sendsthe own information and information of other mobile terminal nodes around to the server at a specific time interval; after receiving the information, the server analyzes the information into a standard format and stores the information in a database module, and then calls the positioning algorithm processing module to process the information, further calculates the position of a target mobile terminal, and returns the position to a user. According to the positioning system disclosed by the invention, when a target communication system is abnormal, the remote positioning of a target can still be realized through the system; and the positioning method uses the revised positioning weight coefficient to calculate the position, so that the adaptability of the positioning algorithm can be realized, the positioning error can be reduced, and the positioning accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless terminal positioning, in particular to a wireless positioning system and method based on multiple mobile terminals. Background technique [0002] Wireless communication is different from wired communication. Wireless mobile positioning refers to the use of measured values ​​such as signal frequency, phase, and propagation time received by a wireless receiver mounted on a mobile terminal to calculate the position of the terminal in a specific coordinate system through a certain algorithm. The problem of wireless mobile positioning has been extensively studied in the past few decades, and positioning research has focused on military target tracking and navigation. Due to the limitations of radio equipment mobility and data processing capabilities, with the development of electronic technology and wireless communication, the research scope and application scenarios of mobile terminal positioning and...
