Description

Technical Field

[0001] This application relates to the field of circuit testing, and in particular to a method and related equipment for detecting wiring abnormalities. Background Technology

[0002] There are two types of wiring abnormalities in outdoor communication equipment. One is the issue of excessively thin power cables. This problem can cause intermittent power outages. Specifically, when the equipment is operating at high power, the increased current, coupled with the increased impedance due to the thin cable, leads to a large voltage drop and consequently, a voltage drop below the equipment's normal operating voltage, triggering a power outage. After the power outage, the voltage at the equipment's terminals returns to normal, causing the equipment to restart. This cycle repeats, significantly impacting service operations. The other issue is that excessively thin cables may have a current-carrying capacity less than the equipment's operating current, leading to high-temperature aging and, in severe cases, even a risk of fire.

[0003] Another type of wiring abnormality is that the equipment's grounding wire is not grounded. This means that the equipment's grounding wire has been cut due to theft, or that poor grounding was caused from the beginning due to poor construction. The main impacts are the risk of lightning protection failure or, in certain special cases, the risk of carbonization.

[0004] To address the aforementioned issues, the current main solution is to conduct on-site inspections and manual checks. However, with tens of millions of communication devices on the network, conducting on-site inspections one by one is too costly and inefficient. Summary of the Invention

[0005] This application provides a wiring abnormality detection method and related equipment. Using this application is beneficial to improving the efficiency of wiring abnormality detection and reducing detection costs.

[0006] In a first aspect, embodiments of this application provide a wiring abnormality detection method. This method is applied to a detection device, which is applied to a power supply system. The power supply system further includes a power supply device and multiple electrical devices, with the first poles of the multiple electrical devices connected together. The wiring abnormality detection method includes:

[0007] The testing equipment determines the loop impedance between each electrical device and its power supply in a plurality of electrical devices; the testing equipment determines the first-pole impedance corresponding to each electrical device based on the loop impedance between each electrical device and its power supply; the testing equipment determines whether there are any devices with abnormal wiring based on the multiple first-pole impedances corresponding to the multiple electrical devices.

[0008] Among them, wiring abnormalities include electrical equipment not being grounded and / or the wire diameter of the power line between the electrical equipment and the power supply equipment being less than the wire diameter threshold.

[0009] As can be seen, when the wiring is normal, the first-pole impedances of multiple electrical devices are the same or have small differences. Therefore, in this case, the detection equipment determines whether there are any devices with abnormal wiring based on the multiple first-pole impedances of the multiple electrical devices. In this way, large-scale detection of wiring abnormalities in electrical devices can be achieved, which helps to improve detection efficiency and reduce detection costs.

[0010] In conjunction with the first aspect, in one possible implementation, the second poles of multiple electrical devices are respectively connected to multiple second poles of the power supply equipment via second pole power lines, and the first poles of multiple electrical devices are all connected to the first pole of the power supply equipment via first pole power lines; the first poles of multiple electrical devices are all grounded through their respective grounding terminals, and the grounding terminals of the power supply equipment are connected, and the grounding grids of the multiple electrical devices and the power supply equipment are the same.

[0011] In conjunction with the first aspect, in one possible implementation, the detection device determines whether there are devices with abnormal wiring based on multiple first-pole impedances corresponding to multiple electrical devices, including:

[0012] The detection equipment determines the maximum and minimum values ​​from the multiple first-pole impedances corresponding to multiple electrical devices. If the difference between the maximum and minimum values ​​exceeds the difference threshold, the detection equipment determines that there are devices with abnormal wiring among the multiple electrical devices. If the difference between the maximum and minimum values ​​does not exceed the difference threshold, the detection equipment determines that there are no devices with abnormal wiring among the multiple electrical devices.

[0013] By determining whether the difference between the maximum and minimum values ​​of the multiple first-pole impedances corresponding to multiple electrical devices exceeds a difference threshold, rather than comparing them pairwise, it is possible to determine whether any of the multiple electrical devices have wiring abnormalities. This facilitates the rapid detection of wiring abnormalities in a large number of electrical devices.

[0014] In conjunction with the first aspect, in one possible implementation, the detection device determines the loop impedance between each of a plurality of electrical devices and the power supply device, including:

[0015] The detection equipment acquires the first voltage value, second voltage value, first current value, and second current value of each electrical device. The first voltage value and first current value are the voltage and current values ​​of each electrical device under a first power, and the second voltage value and second current value are the voltage and current values ​​of each electrical device under a second power. The first power and second power are not the same. Based on the first voltage value, second voltage value, first current value, and second current value, the detection equipment calculates the loop impedance between each electrical device and the power supply equipment.

[0016] It can be seen that by calculating the loop impedance between each electrical device and the power supply device using the voltage and current values ​​of each electrical device under two different power levels, the loop impedance between each electrical device and the power supply device can be obtained quickly. This improves the efficiency of determining the first-pole impedance of each user device based on the loop impedance, thereby improving the efficiency of determining whether multiple electrical devices have wiring abnormalities based on the multiple first-pole impedances corresponding to multiple electrical devices.

[0017] In conjunction with the first aspect, in one possible implementation, the detection device determines the first-pole impedance corresponding to each electrical device based on the loop impedance between each electrical device and the power supply device, including:

[0022] Among them, wiring abnormalities include electrical equipment not being grounded and / or the wire diameter of the power line between the electrical equipment and the power supply equipment being less than the wire diameter threshold.

[0023] In conjunction with the first aspect, in one possible implementation, the second poles of multiple electrical devices are respectively connected to multiple second poles of the power supply equipment via second pole power lines, and the first poles of multiple electrical devices are all connected to the first pole of the power supply equipment via first pole power lines; the first poles of multiple electrical devices are all grounded through their respective grounding terminals, and the grounding terminals of the power supply equipment are connected, and the grounding grids of the multiple electrical devices and the power supply equipment are the same.

[0024] In conjunction with the second aspect, in one possible implementation, regarding determining whether multiple electrical devices have wiring abnormalities based on multiple first-pole impedances corresponding to multiple electrical devices, the determining unit is specifically used for:

[0025] The maximum and minimum values ​​are determined from the multiple first-pole impedances corresponding to multiple electrical devices. If the difference between the maximum and minimum values ​​exceeds a threshold, it is determined that there are devices with abnormal wiring among the multiple electrical devices; if the difference between the maximum and minimum values ​​does not exceed the threshold, it is determined that there are no devices with abnormal wiring among the multiple electrical devices.

[0026] In conjunction with the second aspect, in one possible implementation, the computational unit is specifically used for:

[0027] Obtain the first voltage value, second voltage value, first current value, and second current value for each electrical device. The first voltage value and first current value are the voltage and current values ​​of each electrical device under a first power, and the second voltage value and second current value are the voltage and current values ​​of each electrical device under a second power. The first power and second power are not the same. Calculate the loop impedance between each electrical device and the power supply device based on the first voltage value, second voltage value, first current value, and second current value.

[0028] In conjunction with the second aspect, in one possible implementation, regarding determining the first-pole impedance corresponding to each electrical device based on the loop impedance between each electrical device and the power supply device, the determining unit is specifically used for:

[0040] The terms “first,” “second,” “third,” and “fourth,” etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order.

[0041] "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating three possible relationships. For example, A and / or B means: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0042] The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Figure 1 This is a schematic diagram of a system architecture provided for an embodiment of this application. Figure 1 As shown, the system architecture includes a power supply device 110, multiple power-consuming devices 120, and a detection device 130.

[0044] Among them, the power supply equipment 110 is a device used to supply power to the electrical equipment 120. It can be a photovoltaic power supply device, a mains power supply device, a battery storage power supply device, etc. Of course, it can also be other power supply equipment, which is not limited here.

[0045] Equipment 120 can be base stations, macro base stations, micro base stations, relay base stations, etc., and of course, it can be other equipment as well, without limitation here.

[0046] The detection device 130 is a device with processing capabilities, such as a network management device, handheld device, portable device, server, etc. Of course, it can also be other detection devices; no limitation is made here. The detection device 130 can obtain the voltage and current from the electrical device 120.

[0047] for Figure 1 The system architecture shown has issues during actual construction, such as the power cable between electrical equipment 120 and power supply equipment 110 being too thin or the grounding wire of electrical equipment 120 not being grounded. The current main solution to this problem is to manually inspect the equipment during on-site inspections. However, with tens of millions of electrical devices, the economic cost of inspecting each one is too high and the efficiency is low.

[0048] To address the aforementioned problems, this application provides a method for detecting abnormalities in the grounding wire of a device. Figure 1 A system for implementing this method.

[0049] like Figure 1 As shown, the negative terminals of multiple electrical devices 120 are respectively connected to multiple negative terminals of power supply device 110. In one example, the negative voltage of power supply device 110 can be -48V, but other values ​​are also possible and not limited here. The positive terminals of multiple electrical devices 120 are all connected to the positive terminal of power supply device 110, meaning that multiple electrical devices 120 share a single positive terminal. In one possible implementation, the positive terminals of multiple electrical devices 120 are connected to the grounding terminal of power supply device 110, and the grounding terminal of power supply device 110 is grounded. This application will subsequently describe the situation using the grounding of the positive terminals of multiple devices as an example. It is understood that in a specific implementation, the grounded terminal can be either the positive or negative terminal of each device, and this application is not limited thereto.

[0050] See Figure 2 , Figure 2 This is a flowchart illustrating a wiring abnormality detection method provided in an embodiment of this application. The method is applied to... Figure 1 130 testing equipment.

[0051] S201. The testing equipment determines the loop impedance between each electrical device and the power supply device in a plurality of electrical devices.

[0052] Specifically, the testing equipment connects to multiple electrical devices and can collect the voltage and current values ​​of each device. For each device, the testing equipment collects its voltage and current values ​​at two different power levels. For example, the testing equipment acquires the first voltage and current values ​​of each device at a first power level, and the second voltage and current values ​​at a second power level. Based on these values, the testing equipment calculates the loop impedance between each device and its power supply.

[0053] In one example, the loop impedance between the electrical device and the power supply device can be expressed as:

[0054]

[0055] Wherein, U1 and U2 are the first voltage value and the second voltage value, respectively, and I1 and I2 are the first current value and the second current value, respectively.

[0056] S202. The testing equipment determines the first pole impedance corresponding to each electrical device based on the loop impedance between each electrical device and the power supply device.

[0057] The first-pole impedance corresponding to each electrical device is the impedance on the common return path formed by the first-pole power lines of multiple electrical devices and the grounding lines of multiple electrical devices.

[0058] In one example, the first electrode is positive and the second electrode is negative. In another example, the first electrode is negative and the second electrode is positive.

[0059] See Figure 3 , Figure 3 This diagram illustrates the circuit impedance between a power-consuming device and its power supply. The first terminal is positive, and the second terminal is negative. The circuit impedance R is... 回路 The negative impedance R 负极 and positive impedance R 正极 The sum, i.e., R 回路 =R 负极 +R 正极 . Figure 3 As shown, the positive impedance R 正极 It is the impedance of the circuit formed by the positive line and the grounding line between the electrical equipment and the power supply equipment.

[0060] The detection equipment acquires the length of the second-pole power line between each electrical device and its power supply. Based on the power consumption of the electrical device, it queries the configuration information to determine the wire diameter of the second-pole power line between the electrical device and the power supply. It's understood that the wire diameter is the radius or diameter of the power line; whether it's the diameter or radius can be adjusted based on the calculation. It should be noted that the configuration information includes the specifications of the power line between the electrical device and the power supply, including wire diameter and power consumption, which are preset.

[0061] The testing equipment calculates the impedance of the second power line between the electrical device and the power supply equipment based on the length and diameter of the second power line. This impedance is the aforementioned second-pole impedance. The testing equipment then calculates the first-pole impedance for each electrical device based on the loop impedance between each device and the power supply equipment and the second-pole impedance between each device and the power supply equipment.

[0062] Using the above method, the testing equipment can obtain multiple first-pole impedances corresponding to multiple electrical devices.

[0063] S203. The detection equipment determines whether there are any devices with abnormal wiring based on the multiple first-pole impedances corresponding to multiple electrical devices.

[0064] In one feasible implementation, the detection device determines the maximum and minimum values ​​from multiple first-pole impedances corresponding to multiple electrical devices; if the difference between the maximum and minimum values ​​exceeds the difference threshold, the detection device determines that there are devices with abnormal wiring among the multiple electrical devices.

[0065] Among these, wiring abnormalities include the electrical equipment not being grounded and / or the wire diameter of the power cable between the electrical equipment and the power supply equipment being less than the wire diameter threshold. Here, the wire diameter threshold refers to the wire diameter of the power cable between the electrical equipment and the power supply equipment as specified in the above specifications.

[0066] It should be noted that, under normal wiring conditions, the wire diameter of the power cord between the electrical equipment and the power supply equipment meets the preset specifications, and as... Figure 1 As shown, the first pole of the electrical equipment is grounded through a grounding terminal to achieve ground wire shunting, and multiple electrical equipment are grounded together. Under this premise, the first pole impedances of the multiple electrical equipment calculated through the steps in S202 above are the same, or the difference between the first pole impedances of any two electrical equipment is within a preset range. Therefore, the presence of any equipment with abnormal wiring can be determined by the multiple first pole impedances of the multiple electrical equipment. For example, it can be determined whether the difference between the maximum and minimum values ​​of the multiple first pole impedances of the multiple electrical equipment exceeds a difference threshold, thereby determining whether any equipment has abnormal wiring.

[0067] In one feasible implementation, if the detection device identifies a device with a wiring abnormality among multiple electrical devices, the detection device groups the multiple first-pole impedances corresponding to the multiple electrical devices into groups, and then further compares the first-pole impedances of each group in the manner described above to determine the location of the electrical device with the wiring abnormality. Of course, if the location of the electrical device with the wiring abnormality cannot be determined using the above method, the detection device can further group the group containing the first-pole impedances corresponding to the electrical device with the wiring abnormality, and then further compare the first-pole impedances of each group in the manner described above to determine the location of the electrical device with the wiring abnormality.

[0068] As can be seen, the first poles of multiple electrical devices are all connected to the same first pole of the power supply equipment, and the first poles of multiple electrical devices are grounded through a grounding terminal. When the wiring is normal, the impedances of the corresponding first poles of multiple electrical devices are the same or have small differences. Therefore, in this case, the detection equipment determines whether there are any wiring abnormalities in multiple electrical devices based on the impedances of their corresponding first poles. This method enables large-scale detection of wiring abnormalities in electrical devices, improving detection efficiency and reducing detection costs. Furthermore, the determination of whether there are wiring abnormalities in multiple electrical devices based on their corresponding first pole impedances is done by checking whether the difference between the maximum and minimum values ​​of the multiple first pole impedances exceeds a threshold, rather than by comparing each pair of impedances. This facilitates rapid detection of wiring abnormalities in large-scale electrical devices.

[0069] See Figure 4 , Figure 4 This is a schematic diagram of the structure of a testing device provided in an embodiment of this application. The testing device 400 is... Figure 1 The detection device 130 is used in a power supply system, which also includes power supply equipment and multiple electrical devices, wherein the first poles of the multiple electrical devices are connected together, such as...

[0072] Among them, wiring abnormalities include electrical equipment not being grounded and / or the wire diameter of the power line between the electrical equipment and the power supply equipment being less than the wire diameter threshold.

[0073] In one possible implementation, the second poles of multiple electrical devices are respectively connected to the multiple second poles of the power supply equipment via second pole power lines, and the first poles of multiple electrical devices are all connected to the first pole of the power supply equipment via first pole power lines; the first poles of multiple electrical devices are all grounded through their respective grounding terminals, and the grounding terminals of the power supply equipment are connected, and the grounding grid of the multiple electrical devices is the same as the grounding grid of the power supply equipment.

[0074] In one possible implementation, in determining whether there are devices with abnormal wiring among multiple electrical devices based on multiple first-pole impedances corresponding to multiple electrical devices, the determining unit 402 is specifically used for:

[0075] The maximum and minimum values ​​are determined from the multiple first-pole impedances corresponding to multiple electrical devices. If the difference between the maximum and minimum values ​​exceeds the difference threshold, it is determined that there are devices with abnormal wiring among the multiple electrical devices. If the difference between the maximum and minimum values ​​does not exceed the difference threshold, it is determined that there are no devices with abnormal wiring among the multiple electrical devices.

[0076] In one possible implementation, the computing unit 401 is specifically used for:

[0077] Obtain the first voltage value, second voltage value, first current value, and second current value for each electrical device. The first voltage value and first current value are the voltage and current values ​​of each electrical device under a first power, and the second voltage value and second current value are the voltage and current values ​​of each electrical device under a second power. The first power and second power are not the same. Calculate the loop impedance between each electrical device and the power supply device based on the first voltage value, second voltage value, first current value, and second current value.

[0078] In one possible implementation, in determining the second impedance corresponding to each electrical device based on the loop impedance between each electrical device and the power supply device, the determining unit 402 is specifically used for:

[0079] Obtain the length and diameter of the second power line between each electrical device and the power supply device; calculate the impedance of the second power line based on the length and diameter of the second power line; determine the first impedance corresponding to each electrical device by the difference between the loop impedance between each electrical device and the power supply device and the impedance of the second power line between each electrical device and the power supply device.
