Embodiment Construction

[0006] The invention includes signal source (1), pulse distributor (2), indicator light A (3), interface A (4), network cable (5), interface B (6), indicator light B (7); signal source ( 1) Generate a pulse signal to the pulse distributor (2), and the pulse distributor (2) outputs to the indicator light A (3) in eight channels, and outputs it in eight channels to Light B (7). The signal source (1) is made of NE555 chip. When the signal source (1) is working normally, an indicator light D0 flashes to indicate that the signal source (1) is working. The pulse distributor (2) uses the chip CD4022B to distribute the input pulses to eight output terminals in turn; the pin 3 of the signal chip NE555 of the signal source (1) is sent to the pin 14 of the chip CD4022B. Indicator light A (3) and indicator light B (7) have eight-way indication, indicator light A (3) includes eight light-emitting diodes D1, D2, D3, D4, D5, D6, D7, D8; indicator light B (7 ) includes eight light-emitting ...

Abstract

The invention relates to an inspection type dual-indicator network cable open circuit and short circuit detector. The detector comprises a signal source (1), a pulse distributor (2), an indicator lampA (3), an interface A (4), a network cable (5), an interface B (6), and an indicator lamp B (7); the signal source (1) generates a pulse signal to be transmitted to the pulse distributor (2), and thepulse distributor (2) divides the signal into eight paths to be output to the indicator lamp A (3), and divides the signal into eight paths to be output to the indicator lamp B (7) through the interface A (4), the network cable (5) and the interface B (6). The indicator A (3) and the indicator B (7) are sequentially turned on at the same time, and the network cable open circuit and short circuitcan be detected.

Description

technical field [0001] The invention relates to the technical fields of electronics, network and communication, in particular to a network cable detection device which uses electronic technology to solve network communication. Background technique [0002] The network must use network cables, which are often easily damaged during use. The existing network cable detection can only detect continuity, but short-circuit network cables are not easy to use. For this reason, a wheel-type double-indicating network cable detection device that can detect both on-off and short-circuit detection is designed. Contents of the invention [0003] In order to solve the problem of open circuit and short circuit of the network cable, a patrol-type double-indicating network cable open circuit and short circuit detector is designed. The invention includes signal source (1), pulse distributor (2), indicator light A (3), interface A (4), network cable (5), interface B (6), indicator light B (7)...
