Problems solved by technology
When the display board is placed on the antenna head, it is far away from the buttons on the main unit. After operating the corresponding buttons, the user needs to look up to see the working status and power adjustment of the detector. This design is not convenient for use.
If the display board is placed on the support rod close to the button, the user's line of sight must not only move with the scanning of the front antenna head, but also stare at the detection results displayed on the support rod during the detection process, which is very inconvenient to operate.

[0049] Schematic frame of the circuit structure of nonlinear node detector figure 1 Used to indicate the constituent elements and functions of these parts. Electronic circuitry is required for the host 2 to contain the non-linear junction detector. The electronic circuit includes a transmitter 21 , a receiver 23 , a control circuit 22 , a duplexer 24 and a second display panel 26 . Host 2 provides the electrical connections and electromagnetic shielding required by the circuitry of the nonlinear junction detector. A group of buttons 25 are installed on the host computer 2, which are used to control the operation of the nonlinear node detector, adjust the transmission power, transmission frequency and so on. The second display panel 26 on the host computer 2 is used to display the current working status and the transmit power of the detector.
[0050] A first display panel 42 is mounted on the antenna head 4 to provide information to the user of the nonlinear node detector, ...

The invention discloses a nonlinear node detector. The detector comprises an antenna head and a host which are connected with each other by a telescopic rod, an antenna and a first display panel are arranged on the antenna head, a duplexer connected with the antenna by the telescopic rod is arranged in the host, and the duplexer is further connected with a transmitter, a receiver and a control circuit separately; the control circuit is further connected with the transmitter, the receiver, an audio device, a key and a second display panel separately; the first display panel is arranged on the head of the antenna, the second display panel is arranged beside the key, and two columns of LED (Light Emitting Diode) lamp posts and two LED discriminative lamps are arranged on the first display panel. The nonlinear node detector separately displays information to be displayed, so that a user can view the detection result while moving along with the antenna head in front. The second display panel added beside the key is used for displaying the working mode and the transmitting power of the detector, so that the user can also view the change of contents displayed on the second display panel when changing the working state of the detector via the key.
Description
technical field [0001] The invention relates to the technical field of security inspection and explosion removal and technical reconnaissance, in particular to a nonlinear node detector. Background technique [0002] Nonlinear junction detectors are used to detect electronic devices containing semiconductor nonlinear junctions. Semiconductor junctions exist in diodes and triodes, which are the basic elements of electronic circuits and are widely used in various electronic devices. Therefore, it is possible to determine whether there is an electronic device by detecting the semiconductor junction. The principle of the nonlinear node detector is to irradiate a nonlinear node with a sufficiently powerful electromagnetic wave, and detect the harmonic signal of the original incident signal radiated by the nonlinear node. The nonlinear node detector is to determine whether there is a nonlinear node by detecting the harmonic component, and judge the type of the nonlinear node acc...
