Abstract

The invention discloses police positioning equipment, method and system, the equipment comprises a satellite positioning module, an inertial positioning module and a processor, the satellite positioning module is used for positioning according to satellite signals; the inertial positioning module is used for positioning according to the positioning coordinates of the satellite positioning module, the acceleration information and the angular velocity rotation information; the processor is used for executing the following steps: acquiring satellite signal intensity detected by the satellite positioning module; judging whether the satellite signals can be normally received according to the signal intensity; if the satellite signals cannot be normally received, acquiring a first coordinate of a navigation coordinate system obtained by calculating according to the satellite signals most recently and current first acceleration information and first angular velocity rotation information detected by the inertial positioning module; obtaining a second coordinate of the navigation coordinate system according to the first coordinate, the first acceleration information and the first angular velocity information; and positioning according to the second coordinate.

Description

technical field [0001] The invention relates to the technical field of police positioning, in particular to a police positioning device, method and system. Background technique [0002] At present, most of the police positioning devices use walkie-talkie positioning or mobile police communication (police PDA) for positioning, but these police positioning devices all use the Global Navigation Satellite System (GNSS) positioning function for positioning. , once entering the tunnel, the satellite signal will naturally be blocked, and the positioning function will not be realized. According to research, in cities with many tunnels and mountainous areas, the location deviation problem of public security and police positioning devices due to signal occlusion is common. development had serious consequences. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a police positioning device, method and system to solve the problem that...
