Embodiment 1

[0043] This embodiment provides a specific area radio signal detection device, please refer to Figure 1-3 , the device includes:

[0044] The signal detection unit is used to detect radio signals in a specific area; the signal detection unit includes a main unit, an auxiliary unit, and is connected with the main unit and the auxiliary unit for signal control and calculation, and distinguishes the area by comparing the strength of the two signals Internal and external controllers, the controllers are synchronously controlling and transmitting data between the main machine and the auxiliary machine;

[0045] The main antenna senses and receives signals from all directions and is connected to the host through a coupler. The main antenna is more than one combined antenna set in the detection area and evenly distributed in the detection area;

[0046] The sub-antenna senses and receives signals from various directions and is connected to the host through a coupler. The sub-antenn...

Embodiment 2

[0062] The present invention provides a specific area radio signal detection method, characterized in that the method comprises:

[0063] The controller simultaneously receives the radio signals of the main machine and the auxiliary machine, and after synchronous analysis, compares the strength of the signals to distinguish between inside and outside the area.

[0064] Optionally, the synchronous acquisition method for synchronously analyzing the host computer and estimation includes: the host computer needs to wait for the auxiliary computer to prepare, and then issue a unified "start scanning" command, and then the main computer and the auxiliary computer simultaneously complete a frame of sampling and stop, and wait for both sides to scan. When you're all done processing and ready to go, continue with Scanning.

[0065] Optionally, the method includes: the signal strength of the main unit is greater than the signal strength of the auxiliary unit, determining that the radio ...

Abstract

The invention discloses a radio signal detection device and method in a specific area. The signal detection unit is used to detect wireless signals in a specific area; Carry out signal control and calculation, and distinguish the controllers inside and outside the area through the comparison of the strength of the two signals. Inductively receive and connect with the host through a coupler, the main antenna is more than one combined antenna set in the detection area and evenly distributed in the detection area. The auxiliary antenna is connected to the auxiliary machine through a coupler by inductively receiving signals from various directions, and the auxiliary antenna is more than one combined antenna set outside the detection area and evenly distributed outside the detection area.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a device and method for detecting radio signals in a specific area. Background technique [0002] The popularity of radio signals meets the requirements of information communication in people's life, but the accompanying security and confidentiality requirements make it particularly important to detect radio signals in specific areas, such as confidential places and examination rooms. How to accurately determine the area boundary is a technical problem to be solved in the present invention. [0003] In the existing technical solutions, GPS satellite positioning technology is adopted, the known spatial positions of more than three satellites are used, and the space distance intersecting method is used to obtain the undetermined points on the ground. However, considering the influence of various errors, in order to meet the positioning accuracy requirements , At least 4 satellites ...
