With the continuous development of communication technologies, various types of communication services, such as traditional telephone service (plain old telephone service, POST), x digital subscriber line (x digital subscriber line, xDSL) service, gradually appear in people's lives. The realization of these communication services is inseparable from the mutual cooperation of various communication devices, and the communication cable is an important member of these communication devices. A communication cable is usually formed by twisting one pair or more of mutually insulated wires, and is mainly used to transmit electrical signals such as telephone, telegram or other business data. Because the communication cable carries the transmission of electrical signals such as business data, and it is more prone to man-made damage, such as artificially cut off when stolen, accidentally cut by on-site construction personnel, etc., so how to detect the communication cable in time exceptions and maintaining them have become a growing concern.

In the prior art, a complex abnormality detection system is usually set outside the communication cable, and whether the communication cable is abnormal is detected by the controller and the sensor in the abnormality detection system. Such an external anomaly detection system for communication cables will undoubtedly increase the use and maintenance costs of communication cables. Therefore, the existing anomaly detection solutions for communication cables have poor applicability and practicability.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings provided in the embodiments of the present application.

Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a communication system provided by an embodiment of the present application. The abnormality detection method of the communication cable provided by the present application is suitable for the communication system. As shown in FIG. 1 , the communication system may mainly include one network device and multiple user equipments (such as user equipment 1 and user equipment 2 as shown in FIG. 1 ). Wherein, the network device may include a plurality of ports (for ease of understanding, the description will be replaced by network ports below), such as network port 0, network port 1, etc. as shown in FIG. 1 . In practical applications, some network ports of all network ports of a network device establish a communication connection with a plurality of user equipments through a communication cable. As shown in FIG. 1 , the 100 network ports from the network port 0 to the network port 99 of the network device are connected to the 100 user equipments from the user equipment 0 to the user equipment 99 one by one through the first communication cable. The 100 network ports from the network port 100 to the network port 199 are connected to the 100 user equipments from the user equipment 100 to the user equipment 199 one by one through the second communication cable. It can be understood that FIG. 1 is only an example, and the network device may actually include more network ports, and may establish communication connections with more user equipment through more communication cables. The number of network ports of the network device, the number of user devices, and the number of communication cables between the two are not specifically limited. In actual implementation, each network port of a network device is connected to a user equipment through a pair of wires (also called a wire pair, which is assumed to include a first wire and a second wire) in a communication cable . In actual use, a pair of wires corresponding to each network port can be insulated with different color sequences and evenly twisted into pairs. It should be noted that, for a certain network port, its corresponding first wire and second wire can also be called A wire and B wire. in lieu of description. As shown in FIG. 1 , the network port 0 is connected to the user equipment 0 through the first wire 01 and the second wire 02 in the first communication cable. Here, the preset connection relationship between other network ports of the network device and the user equipment is similar, and details are not described herein again.

It should be supplemented that the above-mentioned network device may specifically be a device that is directly connected to the user equipment through a communication cable, such as a switch, a local communication server, and the like. Each of the above-mentioned user equipments may specifically be wired telephones, digital televisions, and other equipments that need to use communication cables.

The above-mentioned communication cable may specifically be a copper cable, an optoelectronic composite cable, etc., which is not specifically limited in this application.

In practical applications, in order to detect the abnormality of the communication cable between the network equipment and the user equipment and remind the relevant personnel to maintain it, a complex abnormality detection system is usually installed outside the communication cable. and sensor to detect whether the communication cable is abnormal. This method for the external detection system for the communication cable will undoubtedly increase the use and maintenance cost of the communication cable. Therefore, the existing anomaly detection solution for the communication cable has poor applicability and practicability.

Therefore, the technical problem to be solved by this application is: how to simply and accurately determine whether a communication cable is abnormal, so as to reduce the cost of abnormality detection of the communication cable and improve the applicability and practicability of the abnormality detection method of the communication cable.

This method is applicable to the communication system shown in FIG. 1 , and can be specifically executed by the network device shown in FIG. 1 . The method for detecting abnormality of the communication cable provided by the embodiment of the present application will also be described in detail below with reference to the communication system shown in FIG. 1 . describe. As shown in Figure 2, the abnormality detection method may include the following steps:

S201, the network device determines N1 first network ports connected to the target communication cable according to the cable-network port association relationship corresponding to the network device.

In some feasible implementation manners, after it is determined that the abnormality detection of the communication cable is required, the network device may select a communication cable from one or more communication cables connected to it and determine it as the target communication cable, and then according to The corresponding cable-network port association relationship determines N1 network ports connected to the target communication cable (for the convenience of distinction, the description will be replaced by the first network port below). Here, N1 is a positive integer. The cable-network port association relationship corresponding to the above network device is used to indicate the communication cable connected to each network port of the network device. For example, as shown in FIG. 1 , the cable-network port association relationship corresponding to the network device can indicate that the 100 network ports of the network device from network port 0 to network port 99 are connected to the first communication cable, and the network port of the network device is connected to the first communication cable. The 100 network ports from 100 to network port 199 are connected to the second communication cable. It should be noted that the above N1 first network ports may be all network ports connected to the target communication cable, or may be part of the network ports connected to the target communication cable, which is not limited in this application.

In specific implementation, when the network device determines that the preset detection trigger condition is satisfied, it can determine that the abnormality detection of the communication cable is required. Here, the above-mentioned detection trigger condition may specifically be the arrival of the preset detection time, or the abnormality detection control instruction input by the user is received, or the abnormality report fed back by some user equipment is detected, etc., which is not specifically limited in this application. . Then, the network device may select a communication cable from among the one or more communication cables to which it is connected as the target communication cable. The network device can then extract its corresponding cable-network port association. Here, the cable-network port association relationship may be pre-configured by the network device, or may be acquired by the network device in real time from other devices connected to it. The method is not specifically limited. Then, the network device can find all network ports connected to the target communication cable from its corresponding cable-network port association, and determine the N1 first network ports from among all the network ports connected to the target communication cable . For example, when the target communication cable determined by the network device is the above-mentioned first communication cable and N1 is equal to 5, the network device can connect the network port 0, network port 1, network port 2, network port 3 and network port to which the target communication cable is connected The five network ports of port 4 are determined as the above N1 first network ports.

S202, the network device acquires an abnormality determination parameter corresponding to each of the first network ports in the N1 first network ports.

In some feasible implementation manners, after determining the N1 first network ports connected to the target communication cable, the network device may acquire the abnormality judgment parameter corresponding to each of the above N1 first network ports. It should be noted here that, in this embodiment of the present application, the abnormal decision parameter corresponding to any network port of the network device may specifically include the real-time port status of the any network port or the first wire connected to the any network port and the first wire The measured value of the electrical parameters between the two wires.

In a specific implementation, after determining the above N1 first network ports, the network device can acquire the abnormality judgment parameters corresponding to each first network port from the outside line detection module. Here, the above-mentioned outside line detection module is mainly used to perform real-time detection on the port status of each network port of the network device or the electrical parameters between the connected first wire and the second wire, and generate corresponding abnormal judgment parameters. The outside line detection module may be included in the above-mentioned network device, or may be a module independent of the network device, which is not specifically limited in this application.

It should be noted here that the real-time port state of any network port mentioned above is the current port state of the any network port obtained by the network device in real time. In actual implementation, any network port may have a variety of different port states, which is usually related to the communication service carried by the communication cable connected to the any network port (here, it can also be understood as the load carried by the any network port). communication service) is related to the service type. For example, take the network port 0 in FIG. 1 and the first communication cable connected thereto as an example. In the scenario that the first communication cable carries the POST service, the network port 0 may include at least two port states of an off-hook lock state and an on-hook state. In a scenario where the first communication cable carries an xDSL service, the network port 0 may at least include two port states of an online state and an offline state.

It should also be noted that the measured value of the electrical parameters between the first wire and the second wire of any network port mentioned above is the network device performing the electrical parameters of the first wire and the second wire of any network port. Real-time measurements of electrical parameters obtained. In a specific implementation, the measured value of the electrical parameters between the first wire and the second wire may include at least one of the following items: the resistance value measured from the first wire to the second wire (that is, the resistance value measurement direction is from the first lead to the second lead), the resistance value measured from the second lead to the first lead (that is, the resistance measurement direction is from the second lead to the first lead), between the first lead and the second lead Capacitance measurement between the first wire and the ground wire of the network device, capacitance measurement between the second wire and the ground wire of the network device, pre-connection between the first wire and the second wire Set the resistance measurement value or capacitance measurement value corresponding to the detection circuit. It should be noted here that the measured resistance value between the first wire and the second wire is essentially the equivalent resistance value of the user equipment connected to the first wire and the second wire, and the user equipment may contain One or more components with positive and negative polarities (such as diodes, electrolytic capacitors, etc.), so for the measurement of the resistance between the first wire and the second wire, there can be two resistance measurement directions, that is, the first wire The resistance value measurement direction of the second wire, and the resistance value measurement direction of the second wire to the first wire, the resistance value between the first wire and the second wire measured in the two resistance measurement directions Generally not the same. Similarly, it can be understood that when the preset detection circuit connected between the first wire and the second wire includes one or more components with positive and negative polarities, two components of the preset detection circuit are There are also two resistance measurement directions for the measurement of terminal resistance. In the above implementation, the resistance value or capacitance value that can be easily measured between the first wire and the second wire connected to the network port is used as the abnormal judgment parameter of the network port, which can simplify the acquisition process of the abnormal judgment parameter of the network port, and improve the ability to target the network port. Efficiency of abnormality detection of communication cables.

It should be further noted that the measured value of electrical parameters between the first wire and the second wire of any network port includes the resistance measurement value corresponding to the preset detection circuit connected between the first wire and the second wire or In the case of the capacitance measurement value, a corresponding preset detection circuit should be preset between the first wire and the second wire of any network port. For example, please refer to FIG. 3 , which is another schematic structural diagram of a communication system provided by the present application. As shown in FIG. 3 , a corresponding preset detection circuit 03 is preset between the first wire 01 and the second wire 02 of the network port 0 . One end of the preset detection circuit 03 is connected to the first wire 01 , and the other end of the preset detection circuit is connected to the second wire 02 . When the first communication cable is normal, the capacitance measurement value or resistance measurement value at both ends of the preset detection circuit 03 will not change, and will be equal to a constant capacitance value or resistance value. When the first communication cable is abnormal (such as being cut, etc.), the capacitance measurement value or resistance measurement value at both ends of the preset detection circuit 03 is no longer equal to the constant capacitance value or resistance value. Therefore, the resistance value and/or the capacitance value measured at both ends of the preset detection circuit 03 can be used as the abnormal judgment parameter corresponding to the network port 0 .

Optionally, the above-mentioned preset detection circuit may specifically be a remote identification circuit. The remote identification circuit can be connected in parallel between the first wire and the second wire, and the remote identification circuit can specifically include a diode and a resistor with constant resistance. For example, please refer to FIG. 4 , which is another schematic structural diagram of a communication system provided by the present application. As shown in FIG. 4 , a remote identification circuit 031 exists between the first wire 01 and the second wire 02 of the network port 0 , and the remote identification circuit 031 is a preset detection circuit corresponding to the network port 0 . The remote identification circuit 031 specifically includes a diode 0311 and a resistor 0312. One end of the diode 0311 is connected to the second wire 02, the other end of the diode 0311 is connected to one end of the resistor 0312, and the other end of the resistor 0312 is connected to the first wire 01. connected. Assuming that the resistance value of the resistor 0312 is 470K ohms, when the first communication cable is normal, the resistance value at both ends of the remote identification circuit measured in the direction from the first wire 01 to the second wire 02 should be 470K ohms. The resistance value at both ends of the remote identification circuit measured from the wire 02 to the first wire 01 should be 10M ohms. When the first communication cable is abnormal, the resistance value at both ends of the remote identification circuit measured in the direction from the first wire 01 to the second wire 02 will become 10M ohms, and the resistance value from the second wire 02 to the first wire 01 The measured resistance value across the remote identification circuit is still 10M ohms. Therefore, the resistance measurement value between the remote identification circuit 031 and the two ports connected to the first wire 01 and the second wire 02 can be used as the abnormal judgment parameter of the network port 0 . It should also be noted here that the remote identification circuit only needs to be connected in parallel between the first wire and the second wire. This application does not limit whether the remote identification circuit is connected directly or reversely between the first wire and the second wire. between wires.

In the above optional implementation, using a commonly used remote identification circuit as the preset detection circuit between the first wire and the second wire of the network port can improve the compatibility of the abnormality detection method for the communication cable provided by the present application, Thus, the applicability and practicability of the method are improved.

S203, the network device determines whether the target communication cable is abnormal according to the abnormality judgment parameters corresponding to the first network ports.

In some feasible implementation manners, after acquiring the abnormality determination parameters corresponding to each first network port, the network device may determine whether the above-mentioned target communication cable is abnormal according to the abnormality determination parameters corresponding to each first network port. The embodiments of the present application provide various optional manners for determining whether the above-mentioned target communication cable is abnormal, and the various optional manners will be described in detail below.

Option 1:

In this manner, the abnormal parameter corresponding to the network port is the measured value of the electrical parameter between the first wire and the second wire connected to the network port.

In a specific implementation, after acquiring the measured value of the electrical parameter between the first wire and the second wire connected to each first network port, the network device can also obtain the threshold range of the electrical parameter corresponding to each of the first network ports. Here, the electrical parameter threshold range corresponding to each first network port may be configured by the user in real time for the network device, or may be generated by the network device processing the normal electrical parameter values of each network port according to a preset threshold range configuration rule . Wherein, the above-mentioned preset threshold range configuration rule may specifically be: multiplying the preset threshold upper limit coefficient by the normal electrical parameters of each first network port to obtain the upper limit of the electrical parameter threshold of each first network port; The threshold lower limit coefficient is multiplied by the normal electrical parameters of each first network port to obtain the lower limit of the electrical parameter threshold of each first network port, and each first network port is constituted by the upper limit of the electrical parameter threshold and the lower limit of the electrical parameter threshold of each first network port Corresponding electrical parameter threshold range. Of course, the above-mentioned preset threshold range configuration rules may also be other feasible solutions, which are not specifically limited in this application. The above-mentioned normal electrical parameter values of each network port are the electrical parameters obtained by measuring the electrical parameters between the first wire and the second wire connected to each network port when the communication cable connected to each network port is normal. value. The following takes the network port 0 and the first communication cable as an example. Assuming that the first communication cable is normal, the measured normal electrical parameter value between the first wire 01 and the second wire 02 is A1, the upper threshold coefficient is p1, and the lower threshold coefficient is p2. After obtaining the above normal electrical parameter value of A1, the network device may determine A1*p1 as the upper limit of the electrical parameter threshold corresponding to network port 0, and may also determine A1*p2 as the lower limit of the electrical parameter threshold corresponding to network port 0. Then, the network device can determine the interval [A1*p2, A1*p1] as the electrical parameter threshold range corresponding to the network port 0.

After acquiring the electrical parameter threshold range corresponding to each first network port, the network device can determine whether the measured value of the electrical parameter between the first wire and the second wire connected to each first network port is within the range of each first network port. The corresponding electrical parameter threshold range. On the one hand, if the network device determines that the measured values of the electrical parameters between the first wires corresponding to the first network ports and the second wires are not within the threshold range of the electrical parameters corresponding to the first network ports, the target communication cable can be determined. abnormal. Optionally, if the network device determines that the target communication cable is abnormal, it may output first abnormal alarm information, where the first abnormal alarm information is used to prompt that the target communication cable is abnormal. On the other hand, if the network device determines that the measured values of electrical parameters corresponding to the N3 first network ports in the N1 first network ports are within the respective corresponding electrical parameter threshold ranges, it can be determined that the target communication cable is normal. Here, N3 is a preset value and is less than or equal to N1. For example, it is assumed that the measured value of the electrical parameter corresponding to each first network port is the measured value of the capacitance between the first wire and the second wire connected to each first network port, and the above N1 first network ports include network port 0, network Port 1 and network port 2, and the corresponding electrical parameter threshold ranges of these three network ports are [0.5μF, 1.5μF], [1.5μF, 2.5μF], [2.5μF, 3.5μF], respectively. If the network device obtains that the measured values of the electrical parameters corresponding to the three network ports are 0.7μF, 1.7μF, and 2.7μF, respectively, the network device can determine that the measured values of the electrical parameters corresponding to the three network ports are in their corresponding electrical parameters. Within the parameter threshold range, the network device may determine that the first communication cable is normal. If the network device obtains that the measured values of the electrical parameters corresponding to the three network ports are 0.5μF, 1.3μF, and 2.1μF, respectively, the network device can determine that the measured values of the electrical parameters corresponding to the three network ports are not in their corresponding electrical parameters. Within the parameter threshold range, the network device can determine that the first communication cable is abnormal, and further output first abnormal alarm information.

In the above implementation, the network device judges whether the target communication cable is abnormal through the measured value of the electrical parameter between the first wire and the second wire connected to each first network port. The method is simple and easy to implement, and can effectively reduce the need for communication cables. The complexity of the anomaly detection method can reduce the cost of anomaly detection.

Optional implementation method two:

In this optional manner, the abnormal parameter corresponding to any network port is the measured value of the electrical parameter between the first wire and the second wire connected to the any network port. The above-mentioned N1 first network ports are some network ports among all the network ports connected by the target communication cable.

In a specific implementation, after obtaining the measured values of electrical parameters between the first wire and the second wire connected to each first network port, the network device can also obtain the range of electrical parameter thresholds corresponding to each of the first network ports. Here, for the process of obtaining the electrical parameter threshold range corresponding to each first network port by the network device, reference may be made to the corresponding content described in the foregoing implementation manner 1, which will not be repeated here. After acquiring the electrical parameter threshold range corresponding to each first network port, the network device can determine whether the measured value of the electrical parameter between the first wire and the second wire connected to each first network port is within the range of each first network port. The corresponding electrical parameter threshold range. If the network device determines that the measured values of electrical parameters corresponding to the N3 first network ports in the N1 first network ports are within the respective corresponding electrical parameter threshold ranges, it can be determined that the target communication cable is normal. Here, N3 is a preset value and is less than or equal to N1.

If the network device determines that the measured values of the electrical parameters between the first wire and the second wire corresponding to each first network port are not within the threshold range of the electrical parameters corresponding to each first network port, the target communication cable can be further obtained. The measured value of the electrical parameter between the first wire and the second wire corresponding to each of the N2 second network ports connected. It should be noted here that the above-mentioned N2 second network ports are some or all of the network ports other than the above-mentioned N1 first network ports among all the network ports connected by the target communication cable. Then, the network device may obtain the electrical parameter threshold range corresponding to each of the N2 second network ports. Here, the network obtains the process of obtaining the threshold range of electrical parameters corresponding to each of the N2 second network ports and the process of obtaining the threshold range of electrical parameters corresponding to each of the N1 first network ports. Similarly, the description will not be repeated here. Then, the network device may determine whether the measured value of the electrical parameter corresponding to each second network port is within the range of the electrical parameter threshold corresponding to each second network port. If the network device determines that the measured values of the electrical parameters corresponding to the second network ports are not within the threshold range of the electrical parameters corresponding to the second network ports, it can be determined that the target communication cable is abnormal. Optionally, the network device may also output first abnormal alarm information, where the first abnormal alarm information is used to prompt that the target communication cable is abnormal. If the network device determines that the measured values of the electrical parameters corresponding to the second network ports are all included in the electrical parameter threshold range corresponding to the second network ports, it can be determined that the target communication cable is normal.

Here, in the case where it is determined that the measured values of electrical parameters between the first wires corresponding to the N1 first network ports and the second wires are abnormal, continue to obtain the difference between the first wires and the second wires corresponding to the N2 second network ports. The measured value of the electrical parameters between the N2 second network ports and the measured value of the electrical parameters between the first wire and the second wire corresponding to the N2 second network ports continue to judge whether the target communication cable is abnormal, so as to avoid the occurrence of some first network ports corresponding to Misjudgment caused by inappropriate electrical parameter threshold range (for example, when the user equipment connected to a network port is replaced, the original electrical parameter threshold range of the network port may no longer be suitable), etc. It can improve the accuracy of anomaly detection.

Optionally, when the network device determines that the measured values of the electrical parameters corresponding to the above-mentioned second network ports are all included in the range of the electrical parameter thresholds corresponding to each of the second network ports, it means that each of the first network ports in the above N1 first network ports is included. There may be a problem with the electrical parameter threshold range corresponding to the port. In this case, the network device may also update the electrical parameter threshold range corresponding to each first network port according to the measured value of the electrical parameter corresponding to each first network port. Specifically, the network device may process the measured values of electrical parameters corresponding to each first network port according to a preset threshold range configuration rule to obtain a new threshold range of electrical parameters corresponding to each first network port. Then, the network device may use the new electrical parameter threshold range corresponding to each first network port as the electrical parameter threshold range used for subsequent determination. Here, when it is found that the electrical parameter threshold range is unreasonable, the electrical parameter threshold range is updated through the measured value of the electrical parameter in time, which can ensure the rationality and reliability of the electrical parameter threshold range corresponding to each first network port. It can avoid the occurrence of misjudgment caused by the threshold range of electrical parameters, and can improve the accuracy of abnormal detection.

Three optional implementations:

In this optional manner, the abnormal parameter corresponding to the network port is the real-time port state of the network port. Here, the POST service is carried on the target communication cable, and the port status of each network port includes at least an off-hook lock status and an on-hook status.

In the specific implementation, the network device can also obtain the historical port status corresponding to each first network port. Here, the historical port status corresponding to any first network port may be: The port state of any one of the first network ports is obtained by detecting the port state of the first network port. Then, the network device can determine whether the port status of each first network port has been switched from off-hook lock state to on-hook according to the historical port state of each first network port and the acquired real-time port state corresponding to each first network port state. If the network device determines that the port state of each first network port has been switched from the off-hook lock state to the on-hook state, it can be determined that the target communication cable is abnormal. If the network device determines that the port states corresponding to the N3 first network ports in the N1 first network ports are still in the off-hook lock state, it can be determined that the target communication cable is normal. Here, N3 is a preset value and is less than or equal to N1.

In an optional implementation, if the network device determines that the target communication cable is abnormal, it can output first abnormal alarm information, where the first abnormal alarm information is used to indicate that the target communication cable is abnormal.

In another optional implementation manner, when the first wire and the second wire of a first network port are short-circuited, the port state of the first network port is the off-hook lock state. Therefore, in order to ensure that the historical port state corresponding to each first network port is an off-hook lock state, the first wire and the second wire connected to each first network port may be set to a short-circuit state in advance.

In the above implementation, in the scenario where the target communication cable carries the POST service, since the real-time port status of each network port is easy to obtain and has good timeliness, it is determined whether the port status of the network port is locked by off-hook. The method of switching to the on-hook state to determine whether the target communication cable is abnormal can ensure the accuracy and timeliness of the detection results, and can effectively improve the efficiency and accuracy of abnormal detection while reducing the cost of abnormal detection.

Optional implementation four:

In this optional manner, the abnormal parameter corresponding to the network port is the real-time port state of the network port. The above-mentioned N1 first network ports are some network ports among all the network ports connected by the target communication cable.

Similar to the second implementation above, in a scenario where the abnormal parameter corresponding to the network port is the real-time port status of the network port, the network device can also improve the accuracy of abnormality detection by rechecking. Specifically, after acquiring the port state corresponding to each first network port, the network device may also acquire the historical port state of each of the above-mentioned first network ports. Here, for the description of the historical port state of the first network port, reference may be made to the content in the foregoing implementation manner 3, and details are not repeated here. Then, the network device may determine whether the port status of each first network port has been switched from the off-hook lock state to On-hook state. If the network device determines that the port states corresponding to the N3 first network ports in the N1 first network ports are still in the off-hook lock state, it can be determined that the target communication cable is normal. Here, N3 is a preset value and is less than or equal to N1.

If the network device determines that the port state of each first network port has been switched from the above-mentioned off-hook lock state to the on-hook state, it can further obtain the real-time data corresponding to each of the N2 second network ports connected to the target communication cable. port status. It should be noted here that the above-mentioned N2 second network ports are some or all of the network ports other than the above-mentioned N1 first network ports among all the network ports connected by the target communication cable. Then, the network device may acquire the historical port status corresponding to each of the N2 second network ports. Then, according to the historical port state corresponding to each second network port and the real-time port state corresponding to each second network port, it is determined whether the port state of each second network port is switched from off-hook lock state to on-hook state. If the network device determines that the port state of each second network port has been switched from the off-hook lock state to the on-hook state, it can be determined that the target communication cable is abnormal. Further, the network device may also output first alarm information, where the first alarm information is used to indicate that the target communication cable is abnormal. If the network device determines that the port states of the N2 second network ports are still in the off-hook lock state, it can be determined that the target communication cable is normal.

Here, when it is determined that the port states of the N1 first network ports are all switched to the on-hook state, continue to obtain the real-time port states of the N2 second network ports and further judge the target according to the real-time port states corresponding to the N2 second network ports Whether the communication cable is abnormal, this can avoid the occurrence of misjudgment caused by the abnormal port state of some first network ports, and can improve the accuracy of abnormal detection.

Optional implementation method five:

In this optional manner, the abnormal parameter corresponding to the network port is the real-time port state of the network port. Here, the target communication cable carries the xDSL service, and the port status of each network port includes at least an online status and an offline status.

In the specific implementation, the network device can obtain the historical port status corresponding to each first network port. Here, the historical port status corresponding to any first network port can be: The port state of any first network port obtained by detecting the port state of a network port. Then, the network device can determine whether the port status of each first network port has been switched from the online state to the offline state according to the historical port status of each first network port and the acquired real-time port status corresponding to each first network port . If the network device determines that the port state of each first network port has been switched from the online state to the offline state, it can be determined that the target communication cable is abnormal. If the network device determines that the port states corresponding to the N3 first network ports in the N1 first network ports are still in the off-hook lock state, it can be determined that the target communication cable is normal. Here, N3 is a preset value and is less than or equal to N1.

In the above implementation, in the scenario where the target communication cable carries the xDSL service, since the real-time port status of each network port is easy to obtain and has good timeliness, it is determined whether the port status of the network port is switched from the online status to the online status. The method of determining whether the target communication cable is abnormal in the offline state can ensure the accuracy and timeliness of the detection results, and can effectively improve the efficiency and accuracy of abnormal detection while reducing the cost of abnormal detection.

In an optional implementation, if the network device determines that the target communication cable is abnormal, it can output first abnormal alarm information, where the first abnormal alarm information is used to indicate that the target communication cable is abnormal.

It can be understood here that, similar to the fourth embodiment above, in the case that the abnormal parameter corresponding to the network port is the real-time port state of the network port and the target communication cable carries xDSL services, the network device can also first determine the above N1 Whether the port state of each first network port in the first network ports is switched from the online state to the offline state. If the network device determines that the port states of the first network ports are not all switched from the online state to the offline state, it can be determined that the target communication cable is normal. If the network device determines that the port status of each first network port is switched from the online state to the offline state, it can further obtain the real-time port status of the N2 second network ports connected by the target communication cable, and then according to the N2 second network ports The real-time port status of the port further determines whether the target communication cable is abnormal. Here, the specific judging process is similar to the above-mentioned optional implementation mode 4, and in order to avoid repetition, details are not repeated here. This way of adding rechecks can also improve the accuracy of anomaly detection.

It should also be noted here that, in actual implementation, the above-mentioned five implementation manners, from optional implementation manner 1 to optional implementation manner 5, may also be used in combination with each other. For example, the network device may first perform preliminary detection through the above-mentioned optional implementation manner 1 to obtain the first detection result. Then, a second detection is performed through the foregoing optional implementation manner 2, optional implementation manner 3, optional implementation manner 4 or optional implementation manner 5 to obtain a second detection result. The network device can then determine whether the first detection result and the second detection result are the same. If it is determined to be the same, the first detection result may be determined as the final detection result. If it is determined that they are not the same, one or more of the above-mentioned five optional implementation manners may be performed again for abnormality detection. Here, there are many possible combinations of the above five optional implementation manners, and any combination of them is within the scope of protection of the present application. In order to avoid repetition, the present application will not list them one by one.

In this embodiment, after determining the multiple first network ports connected to the target communication cable, the network device directly passes the real-time port status of the multiple first network ports or the first wires connected to the first network ports. The measured value of the electrical parameters between the second wire and the second wire is used to quickly determine whether the target communication cable is abnormal. This eliminates the need for an external detection system and reduces the cost of anomaly detection. Moreover, since the real-time port status of the network port or the measured value of the electrical parameters between the connected first wire and the second wire are parameters that are easily obtained by the network device, the complexity of abnormality detection is simplified, and the abnormality can be improved. detection efficiency.

Embodiment 2

Please refer to FIG. 5. FIG. 5 is another schematic flowchart of a method for detecting abnormality of a communication cable according to an embodiment of the present application. This method is also applicable to the communication system shown in FIG. 1 , and can also be executed by the network device shown in FIG. 1 . The abnormal detection method for a communication cable provided by this embodiment will also be described in detail below with reference to the communication system shown in FIG. 1 . . As shown in Figure 5, the method includes:

S501, the network device acquires an abnormality determination parameter corresponding to each third network port in the N1 third network ports of the network device.

In some feasible implementation manners, after it is determined that the abnormality detection of the communication cable is required, the network device may determine N1 third network ports from all the network ports included in the network device. Here, N1 is a positive integer. Then, the network device may acquire the abnormality determination parameter corresponding to each third network port in the above-mentioned N1 second network ports. Here, the abnormal judgment parameter corresponding to any third network port may include the real-time port status of any third network port or the measured value of electrical parameters between the first wire and the second wire corresponding to the any third network port.

In specific implementation, when the network device determines that the preset detection trigger condition is satisfied, it can determine that the abnormality detection of the communication cable needs to be performed. Here, the above-mentioned detection trigger condition may specifically be the arrival of the preset detection time, or the reception of an abnormality detection control instruction input by the user, etc., which is not specifically limited in this application. Then, the network device may select N1 third network ports from all the network ports to which it is connected. Here, the network device may randomly select N1 third network ports from all network ports connected to it, and the network device may also select the N1 network ports that the user equipment has fed back abnormal information as the N1 third network ports. Other preset selection rules may also be used to select the N1 third network ports, and the present application does not specifically limit the manner in which the network device selects the N1 third network ports. Then, the network device may acquire the abnormality determination parameter corresponding to each of the above N1 third network ports. In this embodiment, the specific description of the abnormality judgment parameter corresponding to each network port is consistent with the abnormality judgment parameter corresponding to each network port in the first embodiment. Therefore, the network device obtains the corresponding abnormality judgment parameter of each third network port. For the specific process of the abnormality determination parameter, reference may be made to the process of obtaining the abnormality determination parameter corresponding to each first network port by the network device described in step S202 in the first embodiment, which will not be repeated here.

S502, the network device determines whether there is an abnormal target communication cable according to the abnormal judgment parameter corresponding to each third network port and the cable-network port association relationship corresponding to the network device.

In some feasible implementation manners, after acquiring the abnormality judgment parameters corresponding to each third network port, the network device may determine the abnormality judgment parameters corresponding to each third network port and the cable-network port association relationship corresponding to the network device. Determine whether there is an abnormal target communication cable among the communication cables connected to the network device. Here, the cable-network port association relationship corresponding to the network device indicates the communication cable connected to each network port of the network device.

This embodiment provides various optional manners for determining whether there is an abnormal target communication cable, and the various optional manners will be described in detail below.

Optional implementation method 1:

In this implementation manner, the abnormal judgment parameter corresponding to each third network port is specifically the measured value of the electrical parameter between the first wire and the second wire corresponding to each third network port.

In a specific implementation, the network device may obtain the electrical parameter threshold range corresponding to each of the third network ports. Here, for the specific process for the network device to obtain the electrical parameter threshold range corresponding to each third network port, reference may be made to the process for the network device to obtain the electrical parameter threshold range corresponding to each first network port described in step S203 of the previous embodiment. I won't go into details. Then, the network device can respectively determine whether the measured value of the electrical parameter between the first wire and the second wire connected to each third network port is within the electrical parameter threshold range corresponding to each third network port.

On the one hand, if the network device determines that there are N2 fourth network ports in the N1 third network ports, and the connection between the first wire and the second wire connected to any of the N2 fourth network ports is If the measured value of the electrical parameter is not within the threshold range of the electrical parameter corresponding to any fourth network port, the network device may further determine whether the above-mentioned N2 fourth network ports are simultaneously connected to the target according to the cable-network port association relationship corresponding to the network device. on the communication cable. If the network device determines that the N2 fourth network ports are simultaneously connected to the target communication cable, it can be determined that there is an abnormal target communication cable.

In an optional implementation manner, if the network device determines that the above-mentioned N2 fourth network ports are not connected to the target communication cable at the same time, the abnormality detection operation can be stopped this time, and the detection trigger condition can be continuously determined.

In another optional implementation manner, if the network device determines that the N2 fourth network ports are not connected to the target communication cable at the same time, the network device may further determine that at least two of the N2 fourth network ports are connected communication cable. Then, the network device may use the abnormality detection method described in the foregoing Embodiment 1 to perform abnormality detection on the at least two communication cables respectively.

In yet another optional implementation manner, if the network device determines that there is an abnormal target communication cable, it may output second abnormal alarm information, where the second abnormal alarm information is used to prompt that the target communication cable is abnormal.

On the other hand, if the network device determines that the measured values of electrical parameters between the first wire and the second wire connected to each of the above N1 third network ports are all within the electrical parameter threshold corresponding to each third network port Within the range, it is determined that there is no abnormal target communication cable. Then, the network device may continue to determine whether the detection trigger condition is satisfied.

In this implementation manner, the network device determines whether there is an electrical parameter measurement value between the first wire and the second wire connected to each third network port that can be directly measured and the corresponding relationship between the cable and the network port of the network device. The method of the abnormal target communication cable is simple and easy to implement, which can effectively reduce the complexity of the abnormality detection method for the communication cable, and can reduce the cost of abnormality detection.

Optional implementation method two:

In this optional manner, the abnormal parameter corresponding to the network port is the real-time port state of the network port. Here, the communication cable connected to the network device carries the POST service, and the port state of each network port includes at least an off-hook lock state and an on-hook state.

In the specific implementation, the network device can obtain the historical port status corresponding to each third network port. Here, the historical port status corresponding to any third network port can be: The port status of any third network port obtained by detecting the port status of the three network ports. Then, the network device can determine whether the port state of each first network port is switched from the above-mentioned off-hook lock state to the on-hook state according to the historical port state of each first network port and the acquired real-time port state corresponding to each first network port .

On the one hand, if the network device determines, according to the abnormal judgment parameter corresponding to each third network port, that the N1 third network ports include N2 fourth network ports, and any fourth network port among the N2 fourth network ports If the port state of the port has been switched from the off-hook lock state to the on-hook state, the network device can further determine whether the N2 fourth network ports are simultaneously connected to the target communication cable according to the cable-network port association relationship corresponding to the network device. Here, N2 is a positive integer less than or equal to N1. It should be noted that the network device determines whether the above-mentioned N2 fourth network ports are simultaneously connected to the target communication cable according to the cable-network port association relationship corresponding to the network device, and the operation after the judgment action is described in the above-mentioned implementation mode 1. The network device determines whether the N2 fourth network ports are simultaneously connected to the target communication cable and the operations after the determination are the same. In order to avoid repetition, the details are not described here.

On the other hand, if the network device determines that the measured values of electrical parameters between the first wire and the second wire connected to each of the above N1 third network ports are all within the electrical parameter threshold corresponding to each third network port Within the range, it is determined that there is no abnormal target communication cable. Then, the network device may continue to determine whether the detection trigger condition is satisfied.

It should be added that when the first wire and the second wire of a third network port are short-circuited, the port state of the third network port is the off-hook lock state. Therefore, in order to make the historical port state of each third network port to be an off-hook lock state, the first wire and the second wire connected to each third network port may be configured to be in a short-circuit state in advance.

In this implementation manner, in the scenario where the communication cable of the network device carries the POST service, since the real-time port status of each network port is easy to obtain and has good timeliness, it is determined whether there is a network port based on the port status of the network port. The method of abnormal target communication cable can ensure the accuracy and timeliness of detection results, and can effectively improve the efficiency and accuracy of abnormal detection while reducing the cost of abnormal detection.

Three optional implementations:

In this optional manner, the abnormal parameter corresponding to the network port is the real-time port state of the network port. Here, the communication cable connected to the network device carries the xDSL service, and the port status of each network port includes at least an online status and an offline status.

In specific implementation, the network device may also acquire the historical port status corresponding to each third network port. Then, the network device can determine whether the port state of each third network port is switched from the above-mentioned online state to the offline state according to the historical port state of each third network port and the acquired real-time port state corresponding to each third network port.

On the one hand, if the network device determines, according to the abnormal judgment parameter corresponding to each third network port, that the N1 third network ports include N2 fourth network ports, and any fourth network port among the N2 fourth network ports If the port state of the port has been switched from the online state to the offline state, the network device may further determine whether the N2 fourth network ports are simultaneously connected to the target communication cable according to the cable-network port association relationship corresponding to the network device. Here, N2 is a positive integer less than or equal to N1. Similarly, the network device determines whether the above-mentioned N2 fourth network ports are simultaneously connected to the target communication cable according to the cable-network port association relationship corresponding to the network device and the operation after the judgment action and the network described in the above-mentioned implementation mode one. The device determines whether the N2 fourth network ports are simultaneously connected to the target communication cable and the operations after the determination are the same. In order to avoid repetition, details are not described here.

On the other hand, if the network device determines that the port state of each of the above N1 third network ports is still in the online state, it can be determined that there is no abnormal target communication cable. Then, the network device may continue to determine whether the detection trigger condition is satisfied.

In this implementation manner, in the scenario where the communication cable of the network device carries the xDSL service, since the real-time port status of each network port is easy to obtain and has good timeliness, it is determined whether there is a network port based on the port status of the network port. The method of abnormal target communication cable can ensure the accuracy and timeliness of detection results, and can effectively improve the efficiency and accuracy of abnormal detection while reducing the cost of abnormal detection.

It should be supplemented here that, in actual implementation, the foregoing optional implementation manner 1 and optional implementation manner 2 or optional implementation manner 3 may be used in combination with each other. For example, the network device may first perform preliminary detection through the above-mentioned optional implementation manner 1 to obtain the first detection result. Then, a second detection is performed through the above-mentioned optional implementation manner 2 to obtain a second detection result. The network device can then determine whether the first detection result and the second detection result are the same. If it is determined to be the same, the first detection result may be determined as the final detection result. If it is determined that they are not the same, the above detection action can be performed again. Here, there are various scenarios in which the above-mentioned optional implementation mode 1 and optional implementation mode 2 or optional implementation mode 3 are combined with each other, and any combination of any one of the scenarios is within the scope of protection of the present application. In order to avoid repetition, here Will not list them one by one.

In this embodiment, the network device may first determine the N1 third network ports, and then pass the real-time port status of the N1 third network ports or the connection between the first wire and the second wire connected to each third network port. The measured value of the electrical parameters, and the cable-network port correlation of the network device can quickly determine whether there is an abnormal target communication cable. This eliminates the need for an external detection system and reduces the cost of anomaly detection. Moreover, since the real-time port status of the network port or the measured value of the electrical parameters between the connected first wire and the second wire are parameters that are easily obtained by the network device, the complexity of abnormality detection is simplified, and the abnormality can be improved. detection efficiency.
