[0002] With the continuous development of science and technology, people's demand for electricity is increasing, and the scale of power cable projects is also expanding rapidly. In the operation of high and low voltage power cable lines, there are many influencing factors in power cables, and some common faults are very likely to occur. It is mainly divided into two aspects: external factors and internal factors. External factors are the impact of damage to cables during the operation of cable lines. The main reasons are human factors and natural factors. The internal factor is mainly the failure of the internal medium to open the circuit. Cable failure has a great impact on the safety of the entire power grid operation process. The emergence of this safety problem not only has a great impact on the convenience of people's daily life, but also causes huge losses to the interests of enterprises.

[0049] In conjunction with the accompanying drawings, the following describes in detail the pulse signal-based cable internal break detection device, method and electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0050] Embodiment 1

[0051] Figure 1 Schematic diagram of the structure of the cable internal break detection device based on pulse signal provided in the first embodiment of the present application. Figure 1 As shown, specifically including the following:

[0052] The signal sending end 101 is arranged on the cable and is used for sending a preset pulse signal to the core of the cable.

[0053] At least one signal receiving end 102 is arranged in the first direction and / or the second direction of the signal sending end on the cable and is arranged in an equidistant manner to receive the preset pulse signal transmitted by the core of the cable; and identify whether the signal strength of the preset pulse signal is within a first range. If so, enhance the preset pulse signal so that the preset pulse signal reaches a standard range.

[0054] The data processing module 103 is connected to each of the signal receiving ends and is used to perform signal difference recognition based on the pulse signal collected by the signal receiving end to determine whether the signal difference recognition result between the target signal receiving end and the previous signal receiving end meets the preset conditions.

[0055] The location determination module 104 is used to determine the disconnection location according to the location information of the target signal receiving end when a preset condition is met.

[0056] The information display module 105 is used to display the disconnection position and the target signal receiving end ID.

[0057] First, the execution scenario of this solution can be a scenario of fault detection and real-time monitoring of wires and cables. Specifically, the acquisition of power outage location information can be performed by a smart terminal device, such as a smart terminal, or an Internet of Things system.

[0058] Based on the above usage scenarios, it can be understood that the executor of the present application can be the smart terminal device or the Internet of Things system, and no excessive limitations are made here.

[0059] In the present solution, the signal transmitting end 101 may be a signal transmitting device, and the working principle may be to generate a periodic signal with an adjustable repetition frequency. The pulse signal may be a discrete signal with a certain periodicity. The cable may be a wire product used to transmit electrical energy. Usually, the composition of the cable includes one or more cores, and each core has a coating, a total protective layer and an outer sheath. The fiber core here functions to conduct electricity, wherein the core is mainly made of copper core and aluminum core, and the cross-sectional shapes are usually circular, semicircular and fan-shaped. Three-core and four-core low-voltage cables mostly use fan-shaped cores. Depending on the different varieties and specifications of the cable, the core can be made into a single-strand entity or a twisted core. The twisted core is formed by twisting a round single wire and a molded single wire.

[0060] In this solution, the signal transmitter is pre-set on the cable. The laying method of the cable is adapted to local conditions. Depending on the laying environment, it can be buried underground or erected in the air. The position of the signal transmitter is fixed and powered on, and then the signal transmitter is configured, such as selecting the waveform, pulse width, repetition period, etc. of the signal.

[0061] In this solution, the signal receiving end 102 can be a device for receiving signals. For example, a pulse signal receiver mainly receives the signal in the channel and converts it into information in the same physical form as when it is sent, and then the receiving end captures the signal. Channel refers to the communication channel and the medium for signal transmission. The channel here is a wireless "frequency band", which is a data signal transmission channel using wireless channel signals as the transmission medium. The first direction and the second direction can be the left and right sides starting from the signal transmitter, and the first direction or the second direction can be the left or right side of the signal transmitter. Specifically, the signal receiving end can be set on both sides of the signal transmitting end at the same time, or on one side of the signal transmitting end. Equal spacing can be to set each pulse signal receiver at an equal distance on the cable. At this time, the signal receiver can receive the transmitted pulse signal and identify the strength of the received pulse signal. Specifically, the value of RSRP (Reference Signal Receiving Power) can be seen. Usually, a signal greater than -85 is a good signal, and the strength range can also be preset here. The first range here can be when the signal is weak but not disconnected, for example, the first range can be less than -85 but greater than -120. If it is within this range, the pulse signal can be enhanced, for example, an amplifier circuit is set, and the amplification factor of the operational amplifier is adjusted to output the ideal signal power.

[0062] In this solution, the data processing module 103, the target signal receiving end can be a device of the current signal receiving end and the previous signal receiving end, and the signal difference recognition can be to compare the characteristics between the current received signal and the previous received signal. Specifically, the comparison waveform is a common pulse signal waveform preset in advance, such as some pulse signals of waveforms such as rectangular wave, sawtooth wave, bell wave, peak wave, trapezoidal wave and step wave. Pulse amplitude refers to the maximum amplitude of the pulse, the period of the pulse, that is, the time length between two adjacent pulse corresponding points in the periodic pulse. By analyzing the difference of the received signals, it is determined whether the signal difference is within the disconnection range. The preset condition can be the difference range under the abnormal conduction caused by the cable disconnection set in advance. Specifically, the difference between the previous received signal and the current received signal is too large in the process of comparing the parameters, and meets the preset conditions, and it can be determined that this section of the cable is disconnected. For example, if the signal strength fluctuation is set between 20, the signal strength received by the previous receiving end is 90, and the signal strength received by this receiving end is 50, it is judged that the difference recognition result of the receiving end meets the preset conditions.

[0063] In this solution, the data processing module is connected to the signal receiving end, which can be a wired connection through a circuit, or a wireless connection can be established by pre-installing a wireless module, and no further restrictions are made here.

[0064] In this solution, the location determination module 104, the location information can be a section of position between the receiving ends. Specifically, after determining that the difference recognition result meets the preset conditions, it will be detected which receiving end meets the preset conditions, and then the location information will be determined. The location information can be fixed when setting the receiving end. It is also through the number of receiving ends with the signal sending end as the origin, and the distance from the origin is obtained by multiplying the spacing. It can also be possible to install a positioning module at the receiving end to obtain accurate location information.

[0065] In this solution, the information display module 105, the receiving end ID (Identity document, ID card identification number), here is a unique number for each receiving end, for example, based on the signal sending end, if the signal receiving end is unidirectional, it can be named 001, 002, 003, etc., if it is a bidirectional signal receiving end, it can be clearly named 001R and 001L, where R and L refer to the direction. This module will display the receiving end ID and position that meet the preset conditions. For example, if the signal received by 001R meets the preset conditions, the information display will show ID: 001; Position: 40°N, 116° / E.

[0066] Based on this embodiment, optionally, the location determination module is specifically used to:

[0067] In the case where a preset condition is met, determining a previous signal receiving end ID of the target signal receiving end according to the target signal receiving end ID;

[0068] Determine the location information of the target signal receiving end according to the target signal receiving end ID, and determine the location information of the previous signal receiving end according to the previous signal receiving end ID;

[0069] The disconnection position is determined according to the position information of the target signal receiving end and the position information of the previous signal receiving end.

[0070] In this scheme, according to the ID of the target signal receiving end, the ID information of the previous signal receiving end can be obtained by subtracting 1 from the ID, and the relevant position information can be obtained using the previous receiving end ID. The broken cable segment can be determined based on the two receiving ends.

[0071] In this embodiment, a device for detecting internal disconnection of a cable based on a pulse signal is invented, and the device includes: a signal transmitting end, which is arranged on the cable and is used to send a preset pulse signal to the core of the cable; a data processing module, which is connected to each of the signal receiving ends and is used to perform signal difference recognition based on the pulse signal collected by the signal receiving end to determine whether the signal difference recognition result between the target signal receiving end and the previous signal receiving end meets the preset conditions; a position determination module, which is used to determine the disconnection position based on the position information of the target signal receiving end when the preset conditions are met; an information display module, which is used to display the disconnection position and the ID of the target signal receiving end. The above device can solve the problems of labor-consuming and inefficient manual detection in the prior art and improve the detection efficiency.

[0072] Embodiment 2

[0073] Figure 2 Schematic diagram of the structure of the cable internal break detection device based on pulse signal provided in the second embodiment of the present application. Figure 2 As shown, specifically including the following:

[0074] The signal sending end 101 is arranged on the cable and is used for sending a preset pulse signal to the core of the cable.

[0075] At least one signal receiving end 102 is arranged in the first direction and / or the second direction of the signal sending end on the cable and is arranged in an equidistant manner to receive the preset pulse signal transmitted by the core of the cable; and identify whether the signal strength of the preset pulse signal is within a first range. If so, enhance the preset pulse signal so that the preset pulse signal reaches a standard range.

[0076] The data processing module 103 is connected to each of the signal receiving ends and is used to perform signal difference recognition based on the pulse signal collected by the signal receiving end to determine whether the signal difference recognition result between the target signal receiving end and the previous signal receiving end meets the preset conditions.

[0077] The location determination module 104 is used to determine the disconnection location according to the location information of the target signal receiving end when a preset condition is met.

[0078] The information display module 105 is used to display the disconnection position and the target signal receiving end ID.

[0079] The consistency check module 106 is used to determine the standard signal strength of the preset pulse signal received by each signal receiving end according to the distance information between each signal receiving end and the signal sending end, and collect the measured signal strength of each signal receiving end to determine whether the measured signal strength and the standard signal strength are within the second range; if so, it is determined that the consistency check condition is met; if there is at least one calibrated signal receiving end whose measured signal strength is not within the second range, it is determined that the calibrated signal receiving end does not meet the consistency check condition.

[0080] In this solution, the consistency check module 106, the standard signal strength can be the signal strength received by each receiving end under ideal conditions. Specifically, because the signal strength will attenuate with the distance, the signal strength received by the latter receiving end is weaker than that of the former receiving end, but each receiving end has a signal enhancement module, that is, only the first receiving end to the second has an attenuated signal, and the subsequent enhanced signal reaches stability. For example, the signal strength of 001 is 100, and it attenuates due to distance. The signal strength received by 002 is 90. 002 enhances the signal to 100 through its own signal enhancement device and transmits it to 003. The subsequent signals received should all be 90.

[0081] The measured signal strength may be the signal strength data actually received by the receiving end. Because the signal is always lost due to external factors, for example, the signal strength of 001 is 100, 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. At this time, 003 in the example is not within the second range, and the 003 receiving end does not meet the consistency check condition. Specifically, it may be a problem with the machine itself or interference caused by the environment.

[0082] In this embodiment, the above device is further improved: the consistency check module 106 is used to determine the standard signal strength of the preset pulse signal received by each of the signal receiving ends according to the distance information between each of the signal receiving ends and the signal sending end, and collect the measured signal strength of each of the signal receiving ends to determine whether the measured signal strength and the standard signal strength are within the second range; if so, it is determined that the consistency check condition is met; if there is at least one calibration signal receiving end whose measured signal strength is not within the second range, it is determined that the calibration signal receiving end does not meet the consistency check condition. By adding a consistency check module, it is possible to avoid interference from the receiving end itself that causes erroneous judgment of the path, making the detection device more reasonable.

[0085] The signal sending end 101 is arranged on the cable and is used for sending a preset pulse signal to the core of the cable.

[0086] At least one signal receiving end 102 is arranged in the first direction and / or the second direction of the signal sending end on the cable and is arranged in an equidistant manner to receive the preset pulse signal transmitted by the core of the cable; and identify whether the signal strength of the preset pulse signal is within a first range. If so, enhance the preset pulse signal so that the preset pulse signal reaches a standard range.

[0087] The data processing module 103 is connected to each of the signal receiving ends and is used to perform signal difference recognition based on the pulse signal collected by the signal receiving end to determine whether the signal difference recognition result between the target signal receiving end and the previous signal receiving end meets the preset conditions.

[0088] The location determination module 104 is used to determine the disconnection location according to the location information of the target signal receiving end when a preset condition is met.

[0089] The information display module 105 is used to display the disconnection position and the target signal receiving end ID.

[0090] A panoramic display module 107, used to generate a panoramic display effect diagram of the cable according to the target signal receiving end ID, the position information of the signal sending end and the position information of each signal receiving end;

[0091] The information display module 105 is also used to receive and display the panoramic display effect diagram.

[0092] In this solution, after determining that the signal strength meets the preset conditions for disconnection, the receiving end ID is displayed and the previous signal end ID is calculated. The panoramic display includes the cable line, the signal transmitter and all receiving ends. The information displayed in the diagram can include the ID and location information of each receiving end. Optionally, the cables between the receiving ends where disconnection is detected will be marked, and if it is a receiving end that does not meet the consistency check, an alarm effect will also be displayed.

[0093] In this embodiment, the above device is improved: the panoramic display module 108 is used to generate a panoramic display effect diagram of the cable according to the target signal receiving end ID, the position information of the signal sending end and the position information of each signal receiving end; the information display module 105 is also used to receive and display the panoramic display effect diagram. Through the panoramic module to visualize the data, it is possible to clearly detect whether the cable is broken. If there is a break, the location information can be quickly determined, further improving efficiency.
