Vehicle 4G mobile phone control system and method integrating shielding and controlling

Abstract

The invention discloses a vehicle 4G mobile phone control system and method integrating shielding and controlling. The system comprises an analog source board, an analog communication power amplifier,a 4G digital baseband board, a digital communication power amplifier, a hybrid filter combiner, a power amplifier antenna, a master controller and an antenna cradle head; the analog communication power amplifier is respectively connected with the analog source board and the hybrid filter combiner; the digital communication power amplifier is respectively connected with the 4G digital baseband board and the hybrid filter combiner; the power amplifier antenna is arranged on the antenna cradle head and connected with the hybrid filter combiner; and the master controller is respectively connectedwith the analog source board, the analog communication power amplifier, the 4G digital baseband board, the digital communication power amplifier and the antenna cradle head. According to the vehicle4G mobile phone control system integrating shielding and controlling provided by the invention, the advantages of analog shielding and digital shielding are taken into account, and 2+3G direct shielding is adopted; and a shielding frequency point is automatically configured according to a frequency sweeping result on a 4G frequency band, the shielding is precise and the coverage distance is long,and the perfect combination of digital + analog is achieved.

Description

technical field [0001] The invention relates to the technical field of mobile phone signal shielding control, in particular to a vehicle-mounted 4G mobile phone control system and method integrating shielding and control.

Problems solved by technology

With the intelligentization of mobile phones, 4G mobile phones are widely used, and some problems that cannot be ignored have also arisen. In some occasions, 4G mobile phones have become a new means of crime, which has an impact on social harmony and stability.

[0003] Mobile phone signal jammers are mainly used in anti-terrorism, mass incidents, riots, etc. Traditional jammers usually need to increase the power to ensure the shielding of the entire frequency band in order to ensure the coverage of the frequency band and range. For some special areas of selective shielding , that is, open the mobile phones of some personnel and shield all other mobile phones, while traditional jammers cannot meet their needs

[0004] Existing jammers are all installed in a fixed way, such as in prisons or other special occasions, which leads to poor mobility and limited applications. Therefore, there is an urgent need for a vehicle-mounted 4G mobile phone shielding control system
