Portable multi-interface communication cable test device

Abstract

The invention discloses a portable multi-interface communication cable test device. The portable multi-interface communication cable test device comprises a network tester, a signal relay module and amultifunctional interface, wherein the signal relay module and the multifunctional interface are arranged on a relay plugin shell, an output, an input and a control signal of the signal relay moduleare connected with the network tester in a pluggable way by a RJ45 interface on the relay plugin shell, an inner-side signal line of the multifunctional interface is connected with the signal relay module, a light-emitting diode group is further arranged on the relay plugin shell and is matched with each plug, and the numbers of each group of light-emitting diodes are equal to numbers of corresponding plugs or pin numbers of the interfaces. An interface conversion device is matched on the basis of an existing network tester, interfaces M2 and RS232 can be simultaneously matched, the test stepand method of the network tester can be expanded to 2M lines and RS232 cables by matching the interfaces, the test defect of a universal meter is prevented, and reliable and convenient test is performed on the cable.

Description

Technical field: [0001] The invention relates to the field of electric power communication, in particular to a portable multi-interface communication cable testing device. Background technique: [0002] Among the existing business interfaces of the power communication system, the most common ones are 2M coaxial interface, RJ45 interface and RS232 interface. Common 2M coaxial interfaces include BNC and L9, RS232 interfaces include RS232 pin type and hole type, and RJ45 interfaces include T568A or T568B. Some devices use two different interface combinations, such as Cisco equipment. The 2M cable is L9 and RJ-45, etc., which increases the difficulty of testing. [0003] When the multimeter is tested for a long time, the test data is unreliable and the result is not intuitive; the two ends of the cable are generally longer, the interface core is thinner and smaller, and the diameter is generally .5-1MM. Mistakenly touching other wire cores will cause errors in the results, whi...

Common 2M coaxial interfaces include BNC and L9, RS232 interfaces include RS232 pin type and hole type, and RJ45 interfaces include T568A or T568B. Some devices use two different interface combinations, such as Cisco equipment. 2M cables are used for L9 and RJ-45, etc., which increases the difficulty of testing

[0003] When the multimeter is tested for a long time, the test data is unreliable and the result is not intuitive; the two ends of the cable are generally longer, the interface core is thinner and smaller, and the diameter is generally .5-1MM. Mistaking other wire cores will cause errors in the results, and repeated confirmation is required in the actual test
