Multifunctional line tracking device

Abstract

The invention provides a multifunctional line tracking device which comprises an emitter and a receiver. The emitter comprises a first center processing module, an alignment decoding module, a first amplifying module, an emission interface module, a first alignment indication circuit, a first processing module, a pulse difference generation module and a pulse counting module. A master frequency signal generated by the first center processing module is amplified through the first amplifying module into an amplified signal which is emitted through a wire connected with the emission interface module; the first alignment indication circuit is connected with the alignment decoding module and the emission interface module, and the first center processing module is connected with the alignment decoding module, the first processing module, the pulse difference generation module and the pulse counting module; the receiver comprises a signal receiving module, a second amplifying module, an analog-digital conversion module, a second center processing module, an audio signal generation module and an indicator, and the signal receiving module, the second amplifying module, the analog-digital conversion module, the second center processing module, the audio signal generation module and the indicator are sequentially connected.

Description

technical field [0001] The invention relates to a multifunctional line hunting device. Background technique [0002] With the rapid development of the network and communication industry, the number of network and communication components has increased geometrically, and the difficulty of wiring has further increased. Cable finders and network testers have become essential tools for finding cables during construction and daily maintenance of various metal lines such as network cables and communication cables. [0003] However, the existing non-contact wire finder has a single function, can only find wires, and cannot judge whether the inner core of the line is connected or disconnected; while the network tester can only test whether the cable is connected or disconnected; and cannot measure the length of the cable , all the results cannot be displayed intuitively; the generator and receiver of the non-contact cable finder both use audio signals, and the receiving part of the...

[0003] However, the existing non-contact wire finder has a single function, can only find wires, and cannot judge whether the inner core of the line is connected or disconnected; while the network tester can only test whether the cable is connected or disconnected; and cannot measure the length of the cable , all the results cannot be displayed intuitively; the generator and receiver of the non-contact cable finder both use audio signals, and the receiving part of the receiver uses metal probe induction to receive, when the cable under test When there are interference sources such as AC220, 50HZ nearby, the receiver has poor anti-interference ability and is very susceptible to interference. The received signal has multiple frequencies, which is very messy, the signal strength is not enough, the sound effect is not good, the sensitivity is not high and the noise is loud , thus increasing the difficulty of the detection work
