Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to a long-distance double-wire detection device, a detection method and an electronic device. Background Art

[0002] At present, the connectivity detection of long-distance double-line mainly adopts manual inspection, which directly measures at both ends of the double-line to determine the connectivity of the double-line. Due to the long detection distance of long-distance double-line, manual inspection consumes a lot of manpower, is inefficient, and is easily missed due to bad weather or terrain.

[0003] In order to improve the detection efficiency, the existing technology uses automatic detection equipment to perform long-distance double-line detection, but there are still the following problems:

[0004] 1. In the prior art, the signal transmitter mainly transmits frequency signals, and multiple transponders are arranged at intervals along the duplexed line. After receiving the frequency signal, the transponder triggers the voice signal module, and the signal transmitter determines the connectivity of the duplexed line based on the received voice signal. In this detection method, due to the long length of the duplexed line and the serious signal attenuation between the duplexed lines, the voice signal strength received by the signal transmitter is weak, or even unable to receive the voice signal, resulting in the detection of the duplexed line connectivity error, and in severe cases, even the location of the disconnection cannot be located.

[0005] 2. In the prior art, the signal transmitter mainly transmits the signal, and one of the multiple transponders triggers the voice signal module. The signal transmitter determines the connectivity of the duplex line based on the received voice signal of the transponder. In this detection method, when the disconnection position is close to the transponder, or the duplex line is of poor quality and the signal is severely attenuated, the signal transmitter cannot receive the voice signal of the transponder, resulting in an error in detecting the connectivity of the duplex line. In severe cases, the disconnection position cannot even be located.
