Abstract

The invention discloses a continuous positioning law enforcement recorder. The recorder comprises a base station positioning module, a GPS module, a mobile communication module and a determination control unit. The mobile communication module is connected with the GPS module and used for receiving real-time data from the GPS module. The real-time data comprises position information and data bits used for representing whether current GPS positioning is effective. The determination control unit is connected with the base station positioning module, is connected with the mobile communication module or the GPS module, is used for determining that the law enforcement recorder is located indoors or outdoors at present according to the data bits, and starts the base station positioning module for indoor positioning when that the law enforcement recorder is located indoors is determined. The positioning way of the recorder achieves seamless switching when intersect movement is carried out indoors and outdoors, the continuous positioning effects are achieved, and great convenience is provided for law enforcement work.

Description

technical field [0001] The invention relates to a single police law enforcement recorder and its positioning technology, in particular to a continuous positioning law enforcement recorder. Background technique [0002] The existing law enforcement recorder uses the GPS module to obtain the longitude and latitude information of the geographic location, and then uploads the location information of the law enforcement personnel to the background server through the GSM2G / 3G module. However, when the law enforcement officers move indoors or where the street buildings are sheltered, the GPS module cannot receive positioning information normally and cannot perform effective positioning. The background staff cannot track and check the current location of the law enforcement officers in time, which brings inconvenience to the police work. . In addition, because the GPS module needs to download satellite ephemeris data for the first time, the first positioning is slow, which affects ...
