The device, the method, and the electronic device for detecting a cable internal disconnection based on a pulse signal provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and application scenarios thereof.

Example one

Fig. 1 is a schematic structural diagram of a cable internal disconnection detecting device based on a pulse signal according to an embodiment of the present application. As shown in fig. 1, the method specifically includes the following steps:

and the signal sending end 101 is arranged on the cable and used for sending a preset pulse signal to a wire core of the cable.

The signal receiving end 102 is arranged in a first direction and/or a second direction of a signal sending end on the cable, adopts an equidistant arrangement mode and is used for receiving the preset pulse signal transmitted by a wire core of the cable; and identifying whether the signal intensity of the preset pulse signal is within a first range, and if so, performing enhancement processing on the preset pulse signal to enable the preset pulse signal to reach a standard range.

And the data processing module 103 is connected with each signal receiving terminal and is used for performing signal difference identification according to the pulse signals acquired by the signal receiving terminals so as to determine whether the signal difference identification result of the target signal receiving terminal and the previous signal receiving terminal meets a preset condition.

And a position determining module 104, configured to determine, according to the position information of the target signal receiving end, a disconnection position if a preset condition is met.

And the information display module 105 is used for displaying the open circuit position and displaying the ID of the target signal receiving end.

Firstly, the execution scene of the scheme can be a scene of performing fault detection and real-time monitoring on the electric wire and the cable. Specifically, the information acquisition of the outage position information may be performed by an intelligent terminal device, for example, an intelligent terminal, or an internet of things system.

Based on the usage scenario, it can be understood that the execution subject of the application may be the intelligent terminal device or an internet of things system, which is not limited herein.

In this scheme, the signal transmitting end 101 may be a signal transmitting apparatus, and the working principle may be to generate a periodic signal with adjustable repetition frequency. The pulse signal may be a discrete signal having a certain periodicity. The cable may be a wire product for transmitting electrical energy. Generally, the composition of a cable includes one or more cores, and each of the cores has a coating layer, a total protective layer, and an outer jacket. The fiber core is conductive, wherein the material of the wire core mainly comprises a copper core and an aluminum core, and the cross section of the wire core is generally circular, semicircular and fan-shaped. The three-core and four-core low-voltage cables are provided with multi-purpose fan-shaped wire cores. According to different varieties and specifications of the cable, the wire core can be made into a single-stranded entity or a stranded wire core. The twisted wire core is formed by twisting a round single wire and a forming single wire.

In the scheme, the signal sending end is preset on the cable, the laying mode of the cable can be buried underground or erected in the air according to the laying environment according to local conditions. The position of the signal transmitting end is fixed and electrified, and then the signal transmitting end is subjected to relevant configuration, such as waveform, pulse width, repetition period and the like of a selection signal.

In this embodiment, the signal receiving end 102 may be a device for receiving signals. For example, a pulse signal receiver mainly receives a signal in a channel, converts the signal into information having the same physical form as that of the signal during transmission, and captures the signal by a receiving end. The channel refers to a communication channel, and is a medium for signal transmission. The channel is a wireless "frequency band" which is a data signal transmission channel using a wireless channel signal as a transmission medium. The first direction and the second direction may be left and right from the signal transmitter, and the first direction or the second direction may be left or right from the signal transmitter. Specifically, the signal receiving end may be disposed on both sides of the signal transmitting end, or may be disposed on one side of the signal transmitting end. The equidistant spacing may be such that each pulse signal receiver is disposed equidistant on the cable. At this time, the Signal receiver may receive the transmitted pulse Signal and identify the strength of the received pulse Signal, specifically, it may be seen that the value of RSRP (Reference Signal Receiving Power) is usually greater than-85, which is a good Signal, and here, the strength range may also be preset by itself. The first range here may be where the signal is weak but not open, e.g. the first range may be less than-85 but greater than-120. If the range is within this range, the pulse signal can be subjected to signal enhancement processing, for example, an amplifying circuit is provided, and the amplification factor of the operational amplifier is adjusted, so that the ideal signal power can be output.

In this embodiment, the data processing module 103, the target signal receiving end may be a currently received signal, and the signal difference recognition may be comparing characteristics between the currently received signal and a previously received signal. Specifically, the waveforms are compared, that is, waveforms of common pulse signals preset in advance, such as some pulse signals of waveforms of rectangular wave, sawtooth wave, bell wave, spike wave, trapezoidal wave, step wave, and the like. The pulse amplitude refers to the maximum amplitude of the pulse, and the period of the pulse refers to the time length between corresponding points of two adjacent pulses in the periodic pulse. It is determined whether the signal difference is within the trip range by analyzing the received signal difference. The preset condition may be a difference range in the case of abnormal conduction due to disconnection of the cable set in advance. Specifically, the difference between the previous received signal and the current received signal in the process of comparing the parameters is too large, which meets the preset condition, and it can be determined that the cable is broken. For example, if the signal strength fluctuation is set to be 20, the received signal strength of the previous receiving end is 90, and the received signal strength of the receiving end is 50, it is determined that the difference recognition result of the receiving end meets the preset condition.

In the scheme, the data processing module is connected with the signal receiving end, wired connection can be carried out through a circuit, or connection can be established through a preset wireless module in a wireless mode, and limitation is not performed.

In this scheme, the position determining module 104 may be a section of position between the receiving end and the receiving end, specifically, after the difference recognition result is judged to meet the preset condition, which receiving end meets the preset condition is detected, and then the position information is determined, the position information determining module determines the position information that can be fixed when the receiving end is set, and also obtains the position from the original point by multiplying the distance by the number of receiving ends using the signal transmitting end as the original point, or installing a positioning module at the receiving end to obtain the accurate position information.

In this embodiment, the information display module 105 and the receiving end ID (Identity document) are unique numbers of each receiving end, for example, they may be referred to from the signal transmitting end, if the unidirectional signal receiving end may be named as 001, 002, 003, etc., if the bidirectional signal receiving end may be named as 001R and 001L, where R and L refer to directions. This module can show the receiving terminal ID and the position that accord with the preset condition, for example, the signal that 001R received accords with the preset condition, and the information display will show ID:001; position: 40N, 116/E.

On the basis of this embodiment, optionally, the position determining module is specifically configured to:

under the condition of meeting a preset condition, determining the ID of a previous signal receiving end of the target signal receiving end according to the ID of the target signal receiving end;

determining the position information of a target signal receiving end according to the ID of the target signal receiving end, and determining the position information of a previous signal receiving end according to the ID of the previous signal receiving end;

and determining the open circuit position according to the position information of the target signal receiving end and the position information of the previous signal receiving end.

According to the scheme, according to the ID of the target signal receiving end, the ID minus 1 can be used for obtaining the ID information of the previous signal receiving end, the ID of the previous receiving end can be used for obtaining the related position information, and the broken cable segment can be determined according to the two receiving ends.

In this embodiment, a cable internal disconnection detecting apparatus based on a pulse signal is invented, the apparatus including: the signal sending end is arranged on the cable and used for sending a preset pulse signal to a wire core of the cable; the data processing module is connected with each signal receiving end and used for carrying out signal difference identification according to the pulse signals acquired by the signal receiving ends so as to determine whether the signal difference identification result of a target signal receiving end and the previous signal receiving end meets a preset condition or not; the position determining module is used for determining the open circuit position according to the position information of the target signal receiving end under the condition of meeting the preset condition; and the information display module is used for displaying the open circuit position and the ID of the target signal receiving end. Through above-mentioned device can solve among the prior art that manual detection consumes manpower and inefficiency problem, improved detection efficiency.

Example two

Fig. 2 is a schematic structural diagram of a cable internal disconnection detecting apparatus based on a pulse signal according to a second embodiment of the present application. As shown in fig. 2, the method specifically includes the following steps:

and the signal sending end 101 is arranged on the cable and used for sending a preset pulse signal to a wire core of the cable.

The signal receiving end 102 is arranged in a first direction and/or a second direction of a signal sending end on the cable, adopts an equidistant arrangement mode, and is used for receiving the preset pulse signal transmitted by a wire core of the cable; and identifying whether the signal intensity of the preset pulse signal is in a first range, if so, performing enhancement processing on the preset pulse signal so as to enable the preset pulse signal to reach a standard range.

And the data processing module 103 is connected with each signal receiving end and is used for performing signal difference identification according to the pulse signals acquired by the signal receiving ends so as to determine whether the signal difference identification result of the target signal receiving end and the previous signal receiving end meets a preset condition.

And a position determining module 104, configured to determine, according to the position information of the target signal receiving end, a disconnection position when a preset condition is met.

And the information display module 105 is used for displaying the open circuit position and displaying the ID of the target signal receiving end.

The consistency checking module 106 is configured to determine, according to distance information between each signal receiving end and the signal sending end, a standard signal strength of a preset pulse signal received by each signal receiving end, acquire an actually-measured signal strength of each signal receiving end, and determine whether the actually-measured signal strength and the standard signal strength are within a second range; if yes, determining that the consistency check condition is met; and if the actually measured signal intensity of at least one calibration signal receiving end is not in the second range, determining that the calibration signal receiving end does not meet the consistency check condition.

In this scheme, the consistency check module 106, the standard signal strength may be the signal strength received by each receiving end in an ideal state, specifically, the signal strength may be attenuated along with the distance, so the signal strength received by the next receiving end is weaker than that received by the previous receiving end, but each receiving end has a module for enhancing the signal, that is, only the first receiving end has an attenuated signal to the second receiving end, the signal is enhanced to be stable after the subsequent receiving end passes through, for example, the signal strength of 001 is 100, because of the attenuation due to the distance, the signal strength received by 002 is 90, 002 enhances the signal to 100 through its own signal enhancing device and transmits the signal to 003, and the subsequent signal reception should be 90.

The measured signal strength may be the signal strength data actually received by the receiving end, because the external factor signal is always lost, for example, the signal strength of 001 is one hundred, the signal strength of 002 is 85, the signal strength of 003 is 70, and the signal strength of 004 is 88; the second range may be an acceptable fluctuation range of the signal strength, such as between 80 and 100, and in this case, 003 is not in the second range, and then the receiving end 003 does not satisfy the consistency check condition, specifically, it may be a problem of the machine itself or interference caused by the environment.

In this embodiment, the above apparatus is further improved: the consistency checking module 106 is configured to determine, according to distance information between each signal receiving end and the signal sending end, a standard signal strength of a preset pulse signal received by each signal receiving end, acquire an actually-measured signal strength of each signal receiving end, and determine whether the actually-measured signal strength and the standard signal strength are within a second range; if yes, determining that the consistency check condition is met; and if the actually measured signal intensity of at least one calibration signal receiving end is not in the second range, determining that the calibration signal receiving end does not meet the consistency check condition. By adding the consistency check module, the situation that the receiving end is mistakenly judged to be broken due to interference caused by self reasons can be avoided, and the detection device is more reasonable.
