Split type visualized multi-path signal intelligent detector

Abstract

The invention discloses a split type visualized multi-path signal intelligent detector which comprises a signal detector sending end 5, a signal detector receiving end 6 and a detection socket 7. Thesignal detector sending end 5 comprises a multivibrator 1, a decade counter 2, a power supply 3, a pair of signal cable plugs and multiple LED lamps 4; the multivibrator 1 provides counting pulses forthe decade counter 2; the power supply supplies power to the detection device; the decade counter 2 provides signals for the LED lamps 4; and signal cables to be detected are connected to the detection socket 7. A detection result is visualized and is more visual and clear; the flickering frequency of the LED lamps is adjustable, and use is more human-based; the split design is not limited by theusing distance; a fault occurrence position can be determined intelligently, and convenience is provided for maintenance; and a present loading control system is used, so that test loading is stableand controllable.

Description

technical field [0001] The invention belongs to the technical field of aviation detection. Disclosed is a split-type visualized multi-channel signal intelligent detection device, especially a detection device for efficient and accurate detection of signal cable connection sequence, on-off, and short-circuit in aircraft structural strength tests. Background technique [0002] In the aircraft structural strength test, in the past, the connection sequence, on-off and short-circuit conditions of multi-channel signals such as sensor cables were detected by using a digital multimeter to measure pin by pin at both ends of the signal cable. Since the cable plug is a pin-shaped plug with a dense pin pitch, the contact surface between the digital multimeter measuring pen and it is small, and it is easy to touch other pins during the measurement process, resulting in slow and inaccurate measurement, which affects the detection efficiency. And one signal cable needs to detect as many a...

Problems solved by technology

Since the cable plug is a pin-shaped plug with a dense pin pitch, the contact surface between the digital multimeter measuring pen and it is small, and it is easy to touch other pins during the measurement process, resulting in slow and inaccurate measurement, which affects the detection efficiency

And one signal cable needs to detect as many as dozens of situations, because of the large number of situations, it is easy to miss

However, when the two ends of the cable are far apart, due to the limitation of the length of the digital multimeter measuring pen, it is impossible to measure

If the fault cannot be checked in time, it will have a certain impact on the test
