A new type of digital network line hunting device and method

Abstract

The invention discloses a novel digital network line-hunting device, which is characterized in that it comprises: simultaneously sending and receiving TCP-IP protocol signals to the target cable, a transmitter for sending the line-hunting signal, and a receiver for receiving the line-hunting signal transmitter; the transmitter includes a hunting signal transmitting module for transmitting the hunting signal, an RJ45 network port, and a port flashing module for driving the network port status indicator light of the switch to flash; the hunting signal transmitting module and the port flashing module are all compatible with the RJ45 Network port connection. The invention also discloses a line hunting method. The invention has reasonable and ingenious structural design and simple structure, and realizes the functions of simultaneously sending amplitude modulation signals and sending and receiving TCP-IP protocol to the target cable by using the same RJ45 port. Prompt sound and flashing pattern form dual positioning dimensions. Using this digital network line hunting device to find lines is accurate, reliable and efficient. The dual positioning dimensions basically eliminate the possibility of misjudgment and greatly improve the efficiency of communication cable repair and maintenance. and quality.

Description

technical field [0001] The invention relates to the technical field of line hunting, in particular to a novel digital network line hunting device and method. Background technique [0002] Existing digital network tracers are composed of a transmitter and a receiver. Its working principle is that the transmitter sends an AM signal to the target cable, the receiver receives and demodulates the modulated signal, and then uses the MCU to judge whether the signal is a valid signal, and if it is, an audio sound is sent through the speaker to prompt the user to find the target cables. [0003] In actual communication cable repair and maintenance applications, it is usually necessary to accurately locate the target cable (faulty line) without interrupting other normal communication lines. However, due to the large number of cables connected to the switch and the high frequency of the hunting signal Crosstalk, so it is difficult to accurately locate the target cable only by the rec...

Problems solved by technology

[0003] In actual communication cable repair and maintenance applications, it is usually necessary to accurately locate the target cable (faulty line) without interrupting other normal communication lines. However, due to the large number of cables connected to the switch and the high frequency of the hunting signal Crosstalk, so it is difficult to accurately locate the target cable only by the receiver sensing the effective signal and emitting a prompt tone. It needs repeated tests and comparisons to sense the cable with the strongest signal, and once the judgment is wrong , Interrupting the normal communication line will cause unnecessary losses to the enterprise or the society, so there is an urgent need for a new type of network line hunting device to fill the gap in the market
