Embodiment Construction

[0033] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0034] Please see attached figure 1 , the invention protects a method for measuring communication cable disconnection and wrong wiring sequence. The method is to use a host computer and an auxiliary remote terminal, connect one end of the cable to be tested to the host computer, and connect the other end of the cable to be tested to the auxiliary remote terminal. , at the host, the positive power supply is connected to one end of the first switch K1 through the voltage dividing resistor Rs, one end of the second switch K2 is grounded, and the auxiliary remote end is provided with access resistance R1~access resistance Rn, where n is greater than or equal to A natural number of 2, one end of the access resistance R1~the access resistance Rn is conn...

Abstract

The invention discloses a communication cable breaking and wrongly connected line sequence measuring method and system. Two different cables are connected by adopting two circuit switches in sequencerespectively; a resistor is connected to each cable; and whether a line is conducted or wrongly connected is judged through the value of a sampling voltage between each connected resistor and a voltage dividing resistor. When the measuring method and system is used for measuring the communication cables, if one of the communication cables is broken, other line sequence measuring results are not affected, and the wire quality can be really reflected; if line sequences are randomly crossed, the results also can be accurately measured; and the whole principle involves resistors and diodes, so that the measuring speed is high, the measuring results are not affected by temperature and humidity, and the stability is high.

Description

technical field [0001] The invention discloses a communication cable measurement method and system, in particular to a communication cable disconnection and wrong wiring sequence measurement method and system, belonging to the technical field of cable fault testing. Background technique [0002] Communication cables usually refer to: network cables (composed of 8-core wires internally), telephone lines (composed of up to 6 core wires internally), coaxial cables (composed of 2-core wires internally), USB cables (4-core wires internally Composition), etc. In addition, there are other forms of cables used for communication, which will not be listed here. In integrated wiring, it is necessary to check whether the produced wires are connected and whether the line sequence is correct. If there is no connection or the line sequence is wrong, it will affect the communication quality and effect if it is light, and will cause communication errors and communication failure if it is ser...
