Embodiment Construction

[0044] In conjunction with the accompanying drawings, the present invention is described in detail, but the scope of protection of the present invention is not limited to the following examples, that is, all simple equivalent changes and modifications made with the patent scope of the present invention and the content of the specification are still patents of the present invention. covered.

[0045] Such as figure 1 It is a schematic diagram of the module structure of the integrated jammer of the present invention.

[0046] The lithium battery provides the voltage and current required for the entire circuit to work. After being fully charged once, the first switch K1, the second switch K2, and the third switch K3 are closed and can work for more than 2 hours.

[0047] The blower control circuit 61 detects whether the first switch K1, the second switch K2, and the third switch K3 are closed. When one or more switches are closed, the blower control circuit 61 makes the blower d...

Abstract

The invention discloses a comprehensive interference unit which comprises four interference frequency bands. Technical indexes of the comprehensive interference unit include that working frequencies of CDMA (code division multiple access) 800, CDMA1X and GSM (global system for communication) 900 modes range from 869MHz to 960MHz; the working frequency of a DCS (data communication system) -1800 mode ranges from 1805MHz to 1880MHz; the working frequency of a GPS (global positioning system) mode ranges from 1565MHz to 1585MHz; and working frequencies of TD-SCDMA (time division-synchronization code division multiple access), CDMA2000 and WCDMA (wideband code division multiple access) modes range from 2010MHz to 2045MHz and from 2110MHz to 2167MHz respectively. The interference unit is mainly used in a personal communication mobile phone and position finder, interferes in downlink data chains in the CDMA800, CDMA1X, CDMA2000, GSM900, DCS-1800, GPS, TD-SCDMA and WCDMA modes, and prevents communication and navigation equipment such as the personal mobile phone and a GPS from being tracked. The comprehensive interference unit forms an electric fence net by a specific electromagnetic spectrum in a small-scale place, the mobile phone cannot be connected with a base station, and information and data cannot be acquired, so that negative effects generated by the mobile phone are eliminated, and a safety protection effect is realized.

Description

technical field [0001] The invention relates to a jammer, in particular to a comprehensive jammer, which is mainly used for communication mobile phones and locators and the like. Background technique [0002] In the information age, with the rapid development of communication technology, mobile phones have become an indispensable and important tool for people's daily work and life. However, the widespread use of mobile phones has also produced some problems that cannot be ignored, and they have become new leaking channels or criminal tools. [0003] At present, there are some mobile communication jammers (such as GSM, CDMA, WCDMA) on the market, which block the voice and SMS services of mobile phones in the area of ​​effect, and prevent the leakage of mobile phones within a specific range. However, they are all large in size, strong in radiation, and inconvenient to carry. At the same time, there are not all kinds of interference mobile phones, and there is no integrated in...
