Embodiment Construction

[0011] In order to make the present invention more comprehensible, preferred embodiments are described in detail as follows.

[0012] A 4G vehicle-mounted detection and control positioning system of the present invention includes three pseudo-base station devices 1 placed on the vehicle and respectively located in the frequency band of China Unicom network, the frequency band of the mobile network and the frequency band of the telecommunication network. The appearance of the pseudo-base station device 1 is as follows: figure 1 shown. On the one hand, the three pseudo-base station devices 1 are connected to the omnidirectional antenna, and the omnidirectional antenna is placed on both ends of the vehicle roof; on the other hand, the three pseudo-base station devices 1 are connected to the mobile computer. The IMSI number of the mobile phone carried by the suspect, the three pseudo base station devices 1 send signals to the mobile phone corresponding to the set IMSI number throu...

Abstract

The invention provides a 4G vehicle-mounted investigation and control system. The system is characterized in that single-soldier positioning equipment is worn on an investigator; after the rough position of a suspect is acquired via signals of pseudo base station equipment, the investigator wearing the single-soldier positioning equipment enters the rough position and approaches the suspect; and in the approaching process, the single-soldier positioning equipment sends self positioning information to a mobile computer via a wireless network, so that accurate positioning information of the suspect is acquired. By adopting the system, the position of the indoor suspect can be accurately positioned, so that the following investigation can be conveniently developed.

Description

technical field [0001] The invention relates to a system for accurately locating the position of a suspect. Background technique [0002] In criminal investigation work, it is often necessary to locate the location of the criminal suspect, especially the location of the suspect in the room, so as to facilitate the investigation work. So far, the location of the suspect has been manually located, that is, investigators are sent into the room to find the suspect and give an approximate location. The disadvantage of this method is that it can only give the approximate location of the suspect. Contents of the invention [0003] The problem to be solved by the present invention is to obtain the precise indoor location of the criminal suspect. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is to provide a 4G vehicle-mounted detection and control positioning system, which is characterized in that it includes th...
