Description

TECHNICAL FIELD

[0001] The present application relates to the field of detectors, in particular to a foldable nonlinear node detector. BACKGROUND

[0002] With the development of science and technology, the nonlinear node detector has become an important technical tool and is widely used in security search, monitoring and identification, etc. The device uses the nonlinear response characteristics to detect target signals, transmits a specific frequency fundamental wave, receives the harmonic signals generated by the target object, and uses the fuzzy recognition algorithm and self-learning algorithm in the field of artificial intelligence to analyze and process the signals, so as to identify the electronic equipment with nonlinear nodes. This technology plays an important role in related fields with its large detection area, high detection accuracy, etc.

[0003] The existing nonlinear node detector usually transmits a high-frequency fundamental wave of S band to the target area or target object through its detection module, and captures the second and third harmonics generated by the target object. After analysis and processing of these harmonic signals, the harmonic change rule before and after the fundamental wave transmission can be revealed, and the nonlinear node can be effectively identified.

[0004] However, in order to realize comprehensive and accurate detection, the detection module of the nonlinear node detector often needs an auxiliary detection module to make the detection module close to the area to be detected, especially in higher or inaccessible areas. The auxiliary detection module usually includes a telescopic rod so that the detection module can reach a farther distance. Although the telescopic rod is relatively portable, it is inevitable that the length of the telescopic rod after retraction is still relatively long. At the same time, in order to facilitate handheld operation, the shell of the receiving and display module is usually designed in a long strip shape. Therefore, the length of the shell and the telescopic rod is superimposed, making the overall length of the nonlinear node detector too long to be easily carried.

[0005] As an expensive detection device, the nonlinear node detector usually needs to be stored in a box. Due to the length of the detector, a large size box needs to be equipped, which is not conducive to the storage and carrying of the device, and also increases the transportation cost.
