Description

Abnormality detection method and abnormality detection device for communication cable

Technical Field

The present application relates to the field of communications device detection technologies, and in particular, to an anomaly detection method and an anomaly detection apparatus for a communications cable.

Background

With the continuous development of communication technologies, various types of communication services, such as traditional telephone service (POST) and x digital subscriber line (xDSL) services, are gradually appearing in the life of people. These communication services are implemented without departing from the interoperability of the various communication devices, and the communication cable is an important one of these communication devices. Communication cables are generally formed by twisting one or more pairs of mutually insulated wires, and are mainly used for transmitting electrical signals such as telephone, telegraph or other service data. Since the communication cable carries the transmission work of electrical signals such as service data, etc., and is easily damaged by human, such as being cut by human when stolen, being cut by field constructors by mistake, etc., it has become a problem that people pay more attention to how to detect and maintain the abnormality of the communication cable in time.

In the prior art, a complex abnormality detection system is usually disposed outside the communication cable, and a controller and a sensor in the abnormality detection system are used to detect whether the communication cable is abnormal. The method for externally detecting the abnormality of the communication cable undoubtedly results in increased use and maintenance costs of the communication cable, and therefore, the conventional abnormality detection scheme for the communication cable is poor in applicability and practicability.

In a first aspect, an embodiment of the present application provides an abnormality detection method for a communication cable. The method may be specifically performed by a network device having a network port connected to a user device by a pair of wires in a communication cable. The network device may determine the N1 first network ports connected to the target communication cable according to the cable-network port association corresponding to the network device. Here, the cable-network port association indicates a communication cable to which each network port of the network device is connected. Then, the network device may obtain the anomaly decision parameter corresponding to each first network port. Here, the abnormality decision parameter corresponding to any network port includes a real-time port state of the network port or an actual measured value of an electrical parameter between a first wire and a second wire corresponding to the network port. Then, the network device may determine whether the target communication cable is abnormal according to the abnormality decision parameter corresponding to each first network port.

In the above implementation, after determining the plurality of first network ports connected to the target communication cable, the network device may directly and rapidly determine whether the target communication cable is abnormal through real-time port states of the plurality of first network ports or measured values of electrical parameters between the first wires and the second wires connected to the first network ports. Therefore, an external detection system is not needed, and the abnormity detection cost can be reduced. In addition, the real-time port state of the network port or the measured value of the electrical parameter between the first conducting wire and the second conducting wire which are connected are all parameters which are easy to obtain by the network equipment, so that the complexity of the abnormity detection is simplified, and the efficiency of the abnormity detection can be improved.

Detailed Description

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

Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. The method for detecting the abnormality of the communication cable is applicable to the communication system. As shown in fig. 1, the communication system may mainly include a network device and a plurality of user equipments (e.g. user equipment 1, user equipment 2, etc. shown in fig. 1). Wherein the network device may include a plurality of ports (for ease of understanding, the description will be replaced with a network port), such as network port 0, network port 1, etc. shown in fig. 1. In practical applications, some of all network ports of the network device are communicatively connected to a plurality of user devices through a communication cable. As shown in fig. 1, the 100 network ports from network port 0 to network port 99 of the network device are connected to the 100 user devices from user device 0 to user device 99 one by one through a first communication cable, and the 100 network ports from network port 100 to network port 199 of the network device are connected to the 100 user devices from user device 100 to user device 199 one by one through a second communication cable. It is 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 devices through more communication cables, and the application does not specifically limit the number of network ports of the network device, the number of user devices, and the number of communication cables therebetween in the communication system. In practical implementations, each network port of a network device is connected to a user device through a pair of wires (also referred to as a wire pair, and herein assumed to include a first wire and a second wire) in a communication cable. In practical use, a pair of wires corresponding to each network port can adopt insulating covers with different color sequences and be uniformly twisted into a pair. It should be noted that, for a certain network port, the corresponding first wire and second wire may also be referred to as a wire and B wire, and for convenience of understanding, the description will be collectively replaced by the first wire and the second wire hereinafter. As shown in fig. 1, the network port 0 is connected to the user equipment 0 through the first conductor 01 and the second conductor 02 of the first communication cable. Here, connection relationship presets between other network ports of the network device and the user equipment are similar, and are not described here again.

It should be noted that the network device may specifically be a switch, a local communication server, or the like that is directly connected to the user equipment through a communication cable. The user devices may be specifically wired telephones, digital televisions and other devices that need to use communication cables. The present application does not specifically limit the specific implementation forms of the network device and the user equipment, and the description will be replaced with the network device and the user equipment in a unified manner. The communication cable may be a copper cable, a photoelectric composite cable, or the like, which is not limited in this application.

In practical applications, in order to detect an abnormality of a communication cable between a network device and a user device and remind related personnel of maintenance, a set of complex abnormality detection system is usually disposed outside the communication cable, and a controller and a sensor in the detection system are used to detect whether the communication cable is abnormal. The method for detecting the external communication cable will undoubtedly result in the increase of the use and maintenance cost of the communication cable, so the applicability and practicability of the existing abnormal detection scheme for the communication cable are poor.

Therefore, the technical problem to be solved by the application is as follows: how to simply and accurately judge whether the communication cable is abnormal or not so as to reduce the cost of the abnormal detection of the communication cable and improve the applicability and the practicability of the abnormal detection method of the communication cable.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an anomaly detection method for a communication cable according to an embodiment of the present disclosure. The method is applicable to the communication system shown in fig. 1, and can be specifically executed by the network device in fig. 1, and the method for detecting an abnormality of a communication cable provided in the embodiment of the present application will also be described in detail below with reference to the communication system shown in fig. 1. As shown in fig. 2, the abnormality detection method may include the steps of:

s201, the network device determines N1 first network ports connected with the target communication cable according to the cable-network port association relation corresponding to the network device.

In some possible implementations, after determining that the anomaly detection of the communication cable is required, the network device may select one communication cable from the one or more communication cables connected thereto and determine the communication cable as a target communication cable, and then determine, according to the cable-network port association relationship corresponding to the communication cable, N1 network ports connected to the target communication cable (for convenience of distinction, the description will be replaced with the first network port hereinafter). Here, N1 is a positive integer. The cable-network port association relationship corresponding to the network device is used for indicating a 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 may indicate that 100 network ports from network port 0 to network port 99 of the network device are connected to the first communication cable, and that 100 network ports from network port 100 to network port 199 of the network device are connected to the second communication cable. It should be noted that the N1 first network ports may be all network ports to which the target communication cable is connected, or may be part of network ports to which the target communication cable is connected, which is not limited in the present application.

In specific implementation, when the network device determines that the preset detection trigger condition is satisfied, it may be determined that the anomaly detection of the communication cable needs to be performed. Here, the detection trigger condition may specifically be that a preset detection time arrives, or that an abnormality detection control instruction input by a user is received, or that an abnormality report fed back by some user equipment is detected, and the present application does not specifically limit this. The network device may then select a communication cable from the one or more communication cables to which it is connected as the target communication cable. The network device may then extract its corresponding cable-network port association. Here, the cable-network port association relationship may be preconfigured by the network device, or may be obtained by the network device in real time from other devices connected to the network device. Then, the network device may find all network ports connected to the target communication cable from the cable-network port association relationship corresponding to the network device, and determine the N1 first network ports from all network ports connected to the target communication cable. For example, when the target communication cable determined by the network device is the first communication cable and N1 is equal to 5, the network device may determine 5 network ports, namely, network port 0, network port 1, network port 2, network port 3, and network port 4, to which the target communication cable is connected as the N1 first network ports.

S202, the network equipment obtains the abnormal judgment parameters corresponding to each first network port in the N1 first network ports.

In some possible implementation manners, after determining the N1 first network ports connected to the target communication cable, the network device may obtain the abnormality decision parameter corresponding to each of the N1 first network ports. It should be noted that, in this embodiment of the application, the abnormality decision parameter corresponding to any network port of the network device may specifically include a real-time port state of the any network port or an actual measured value of an electrical parameter between a first conducting wire and a second conducting wire connected to the any network port.

In a specific implementation, after the N1 first network ports are determined, the network device may obtain the abnormality decision parameter corresponding to each first network port from the external line detection module. Here, the external line detection module is mainly used for detecting the port state of each network port of the network device or the electrical parameter between the connected first wire and the second wire in real time and generating a corresponding abnormality judgment parameter. The outside line detection module may be included in the network device, or may be a module independent from the network device, which is not specifically limited in this application.

It should be noted that the real-time port status of any network port described above is the current port status of any network port that is acquired by the network device in real time. In actual implementations, there may be a plurality of different port states for any network port, which are typically related to the traffic type of the communication traffic carried by the communication cable to which the any network port is connected (which may also be understood herein as the communication traffic carried by the any network port). For example, take network port 0 and its connected first communication cable in fig. 1 as an example. In a scenario where the first communication cable carries POST traffic, the network port 0 may include at least two port states, an off-hook locked state and an on-hook state. In a scenario where the first communication cable carries an xDSL service, the network port 0 may include at least two port states, i.e., an online state and a offline state.

It should be noted that the measured value of the electrical parameter between the first conducting wire and the second conducting wire of any network port is an electrical parameter measured value obtained by the network device performing real-time measurement on the electrical parameter of the first conducting wire and the second conducting wire of any network port. In a specific implementation, the measured value of the electrical parameter between the first conductive line and the second conductive line may include at least one of the following items: the resistance value measured from the first wire to the second wire (i.e. the resistance value measuring direction is from the first wire to the second wire), the resistance value measured from the second wire to the first wire (i.e. the resistance value measuring direction is from the second wire to the first wire), the capacitance measured value between the first wire and the second wire, the capacitance measured value between the first wire and the ground wire of the network device, the capacitance measured value between the second wire and the ground wire of the network device, and the resistance measured value or the capacitance measured value corresponding to a preset detection circuit connected between the first wire and the second wire. It should be noted that the measured resistance value between the first conducting wire and the second conducting wire is essentially the equivalent resistance value of the user equipment connected to the first conducting wire and the second conducting wire, and the user equipment may include one or more components (such as a diode, an electrolytic capacitor, etc.) with positive and negative polarities, so that the measurement of the resistance value between the first conducting wire and the second conducting wire may have two resistance value measuring directions, that is, the resistance value measuring direction of the first conducting wire towards the second conducting wire, and the resistance value measuring direction of the second conducting wire towards the first conducting wire, which are generally different from each other in the two resistance value measuring directions. Similarly, it can be understood that when the preset detection circuit connected between the first conducting wire and the second conducting wire includes one or more components with positive and negative polarities, there are two resistance measurement directions for the measurement of the resistors at the two ends of the preset detection circuit. In the implementation, the resistance value or the capacitance value which is easily measured between the first wire and the second wire which are connected with the network port is used as the abnormity judgment parameter of the network port, so that the acquisition process of the abnormity judgment parameter of the network port can be simplified, and the abnormity detection efficiency of the communication cable is improved.

It should be further noted that, in the case that the measured value of the electrical parameter between the first conducting wire and the second conducting wire of any network port includes a resistance measured value or a capacitance measured value corresponding to a preset detection circuit connected between the first conducting wire and the second conducting wire, a corresponding preset detection circuit should be preset between the first conducting wire and the second conducting wire of any network port. For example, please refer to fig. 3, fig. 3 is a schematic diagram of another structure of a communication system provided in the present application. As shown in fig. 3, a corresponding preset detection circuit 03 is preset between the first conductor 01 and the second conductor 02 of the network port 0. One end of the preset detection circuit 03 is connected with the first wire 01, and the other end of the preset detection circuit is connected with the second wire 02. In the normal case of the first communication cable, the capacitance or resistance measurement value at both ends of the predetermined detection circuit 03 will not change and will be equal to a constant capacitance or resistance value. When the first communication cable is abnormal (e.g. cut off), the capacitance or resistance measurement value at both ends of the preset detection circuit 03 is no longer equal to the constant capacitance or resistance value. Therefore, the resistance and/or capacitance values measured at the two ends of the preset detection circuit 03 can be used as the abnormality decision parameters corresponding to the network port 0.

Optionally, the preset detection circuit may be a remote identification circuit. The remote identification circuit may be connected in parallel between the first wire and the second wire, and may specifically include a diode and a constant resistance resistor. For example, please refer to fig. 4, fig. 4 is a schematic diagram of another structure of a communication system provided in the present application. As shown in fig. 4, a far-end identification circuit 031 exists between the first wire 01 and the second wire 02 of the network port 0, and the far-end identification circuit 031 is a preset detection circuit corresponding to the network port 0. The far-end identification circuit 031 specifically includes a diode 0311 and a resistor 0312, one end of the diode 0311 is connected with the second wire 02, the other end of the diode 0311 is connected with one end of the resistor 0312, and the other end of the resistor 0312 is connected with the first wire 01. Assuming that the resistance value of the resistor 0312 is 470K ohms, under normal conditions of the first communication cable, the resistance value measured across the remote identification circuit in the direction from the first wire 01 to the second wire 02 should be 470K ohms, and the resistance value measured across the remote identification circuit in the direction from the second wire 02 to the first wire 01 should be 10M ohms. When the first communication cable is abnormal, the resistance value of the two ends of the remote identification circuit measured in the direction from the first wire 01 to the second wire 02 becomes 10M ohm, and the resistance value of the two ends of the remote identification circuit measured in the direction from the second wire 02 to the first wire 01 is still 10M ohm. Therefore, the measured resistance value between the far-end identification circuit 031 and the two ports connected to the first conductor 01 and the second conductor 02 can be used as the abnormality decision parameter of the network port 0. It should be noted here that the remote identification circuit only needs to be connected in parallel between the first conducting wire and the second conducting wire, and the application does not limit whether the remote identification circuit is connected in the forward direction or in the reverse direction between the first conducting wire and the second conducting wire.

In the optional implementation, a common far-end identification circuit is used as a preset detection circuit between a first wire and a second wire of a network port, so that the compatibility of the method for detecting the abnormality of the communication cable provided by the application can be improved, and the applicability and the practicability of the method are further improved.

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

In some feasible implementation manners, after obtaining the abnormality judgment parameter corresponding to each first network port, the network device may determine whether the target communication cable is abnormal according to the abnormality judgment parameter corresponding to each first network port. The embodiments of the present application provide various alternatives for determining whether the target communication cable is abnormal, and the following detailed descriptions will be made for these various alternatives, respectively.

The first alternative is as follows:

in this embodiment, the abnormal parameter corresponding to the network port is an actual measured value of an electrical parameter between the first conducting wire and the second conducting wire connected to the network port.

In a specific implementation, after the measured value of the electrical parameter between the first conducting wire and the second conducting wire connected to each first network port is obtained, the network device may further obtain a threshold range of the electrical parameter corresponding to each first network port. Here, the electrical parameter threshold range corresponding to each first network port may be configured by the user for the network device in real time, or may be generated by the network device processing the normal electrical parameter value of each network port according to a preset threshold range configuration rule. The preset threshold range configuration rule may specifically be: and multiplying a preset upper threshold limit coefficient by the normal electrical parameters of each first network port to obtain an upper electrical parameter threshold limit of each first network port, multiplying a preset lower threshold limit coefficient by the normal electrical parameters of each first network port to obtain a lower electrical parameter threshold limit of each first network port, and forming an electrical parameter threshold range corresponding to each first network port by the upper electrical parameter threshold limit and the lower electrical parameter threshold limit of each first network port. Of course, the preset threshold range configuration rule may also be other feasible schemes, and this application is not limited in this respect. The normal electrical parameter value of each network port is an electrical parameter value obtained by measuring an electrical parameter between a first wire and a second wire connected to each network port under the condition that a communication cable connected to each network port is normal. In the following, network port 0 and the first communication cable are taken as examples. Assuming that the normal electrical parameter value between the first wire 01 and the second wire 02 is measured as a1 in the case where the first communication cable is normal, the above-mentioned upper threshold coefficient is p1, and the lower threshold coefficient is p 2. After obtaining that the normal electrical parameter value is a1, the network device may determine a1 × p1 as the upper limit of the electrical parameter threshold corresponding to the network port 0, and may further determine a1 × p2 as the lower limit of the electrical parameter threshold corresponding to the network port 0. The network device may then determine the interval [ a1 × p2, a1 × p1] as the electrical parameter threshold range corresponding to network port 0.

After obtaining the electrical parameter threshold range corresponding to each first network port, the network device may respectively determine whether the measured value of the electrical parameter between the first conducting wire and the second conducting wire connected to each first network port is within the electrical parameter threshold range corresponding to each first network port. On the other hand, if the network device determines that the measured values of the electrical parameters between the first conducting wire and the second conducting wire corresponding to each first network port are not within the threshold range of the electrical parameters corresponding to each first network port, it may determine that the target communication cable is abnormal. Optionally, if the network device determines that the target communication cable is abnormal, first abnormal warning information may be output, where the first abnormal warning 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 the electrical parameters corresponding to N3 of the N1 first network ports are within the respective corresponding electrical parameter threshold ranges, it may 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, assuming that the measured electrical parameter value corresponding to each first network port is a capacitance measured value between a first wire and a second wire connected to each first network port, the N1 first network ports include network port 0, network port 1 and network port 2, and the threshold ranges of the electrical parameters corresponding to the three network ports are [0.5 μ F, 1.5 μ F ], [1.5 μ F, 2.5 μ F ], [2.5 μ F, 3.5 μ F ], respectively. If the measured values of the electrical parameters corresponding to the three network ports, which are obtained by the network device, are 0.7 μ F, 1.7 μ F, and 2.7 μ F, respectively, the network device may determine that the measured values of the electrical parameters corresponding to the three network ports are within the threshold ranges of the electrical parameters corresponding to the three network ports, and then the network device may determine that the first communication cable is normal. If the measured values of the electrical parameters corresponding to the three network ports, which are obtained by the network device, are 0.5 μ F, 1.3 μ F and 2.1 μ F, respectively, the network device may determine that the measured values of the electrical parameters corresponding to the three network ports are not within the threshold ranges of the electrical parameters corresponding to the measured values of the electrical parameters, and then the network device may determine that the first communication cable is abnormal, and further output first abnormal alarm information.

In the implementation, the network device judges whether the target communication cable is abnormal or not through the measured value of the electrical parameter between the first wire and the second wire connected with each first network port, the method is simple and easy to implement, the complexity of the abnormality detection method for the communication cable can be effectively reduced, and the cost of abnormality detection can be reduced.

The second optional implementation mode:

in this optional manner, the abnormal parameter corresponding to any network port is an actual measured value of an electrical parameter between the first conducting wire and the second conducting wire connected to the network port. The N1 first network ports are some of all the network ports of the target communication cable connection.

In a specific implementation, after the measured value of the electrical parameter between the first conducting wire and the second conducting wire connected to each first network port is obtained, the network device may also obtain the threshold range of the electrical parameter corresponding to each first network port. Here, the process of the network device acquiring the threshold ranges of the electrical parameters corresponding to the first network ports may specifically refer to the corresponding content described in the first implementation manner, and details are not repeated here. After obtaining the electrical parameter threshold range corresponding to each first network port, the network device may respectively determine whether the measured value of the electrical parameter between the first conducting wire and the second conducting wire connected to each first network port is within the electrical parameter threshold range corresponding to each first network port. If the network device determines that the measured values of the electrical parameters corresponding to N3 of the N1 first network ports are within the threshold ranges of the respective electrical parameters, it is 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 conducting wires and the second conducting wires corresponding to the first network ports are not within the threshold ranges of the electrical parameters corresponding to the first network ports, the network device may further obtain the measured values of the electrical parameters between the first conducting wires and the second conducting wires corresponding to each of the N2 second network ports connected to the target communication cable. It should be noted here that the N2 second network ports are all or part of all the network ports connected by the target communication cable except the N1 first network ports. Then, the network device may obtain the electrical parameter threshold range corresponding to each of the N2 second network ports. Here, the process of the network acquiring the electrical parameter threshold range corresponding to each of the N2 second network ports is similar to the process of the network acquiring the electrical parameter threshold range corresponding to each of the N1 first network ports, and a description thereof is not repeated here. Then, the network device may determine whether the measured electrical parameter value corresponding to each second network port is within the electrical parameter threshold range 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 ranges of the electrical parameters corresponding to the second network ports, it may be determined that the target communication cable is abnormal. Optionally, the network device may further 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 threshold ranges of the electrical parameters corresponding to the second network ports, it may be determined that the target communication cable is normal.

Here, when it is determined that the measured values of the electrical parameters between the first wires and the second wires corresponding to the N1 first network ports are not normal, the measured values of the electrical parameters between the first wires and the second wires corresponding to the N2 second network ports are continuously obtained, and whether the target communication cable is abnormal or not is continuously determined according to the measured values of the electrical parameters between the first wires and the second wires corresponding to the N2 second network ports, so that the occurrence of situations such as misjudgments caused by inappropriate threshold ranges of the electrical parameters corresponding to some first network ports (for example, when a user equipment connected to a certain network port is replaced, the original threshold ranges of the electrical parameters of the network port may no longer be appropriate) can be avoided, and the accuracy of abnormality detection can be improved.

Optionally, when the network device determines that the measured electrical parameter values corresponding to the second network ports are all included in the electrical parameter threshold ranges corresponding to the second network ports, it indicates that there may be a problem in the electrical parameter threshold ranges corresponding to the first network ports of the N1 first network ports. In this case, the network device may further update the electrical parameter threshold range corresponding to each first network port according to the measured electrical parameter value corresponding to each first network port. Specifically, the network device may process the measured electrical parameter value corresponding to each first network port according to a preset threshold range configuration rule to obtain a new electrical parameter threshold range 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 the electrical parameter threshold range is found to be unreasonable, the electrical parameter threshold range is updated in time through the electrical parameter measured value, so that the reasonability and reliability of the electrical parameter threshold range corresponding to each first network port can be ensured, the occurrence of conditions such as misjudgment caused by the electrical parameter threshold range can be avoided, and the accuracy of anomaly detection can be improved.

The third optional implementation mode:

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

In a specific implementation, the network device may further obtain a historical port state corresponding to each first network port, where the historical port state corresponding to any first network port may be: before the anomaly detection, the port state of any first network port is obtained by detecting the port state of any first network port for the last time. Then, the network device may determine whether the port states of the first network ports have been switched from the off-hook locking state to the on-hook state according to the historical port states of the first network ports and the obtained real-time port states corresponding to the first network ports. If the network device determines that the port state of each first network port has been switched from the off-hook locked state to the on-hook state, it may be determined that the target communication cable is abnormal. If the network device determines that the port states corresponding to N3 first network ports of the N1 first network ports still remain in the off-hook locking state, it may 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, first abnormal warning information may be output, where the first abnormal warning information is used to indicate that the target communication cable is abnormal.

In another alternative implementation, 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 an off-hook locking state. Therefore, in order to ensure that the historical port state corresponding to each first network port is in an off-hook locked state, the first wire and the second wire connected to each first network port may be set to a short-circuit state in advance.

The optional implementation mode is four:

in this optional manner, the abnormal parameter corresponding to the network port is a real-time port state of the network port. The N1 first network ports are part of all the network ports connected by the target communication cable.

Similar to the second implementation manner, in a scenario where the abnormal parameter corresponding to the network port is the real-time port state of the network port, the network device may also improve the accuracy of the abnormal detection in a rechecking manner. Specifically, after acquiring the port state corresponding to each first network port, the network device may also acquire the historical port state of each first network port. Here, for the description of the historical port status of the first network port, reference may be made to the content in the third implementation manner, and details are not described here again. Then, the network device may determine whether the port states of the first network ports have been switched from the off-hook locking state to the on-hook state according to the historical port states of the first network ports and the obtained real-time port states corresponding to the first network ports. If the network device determines that the port states corresponding to N3 first network ports of the N1 first network ports still remain in the off-hook locking state, it may 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 states of the first network ports have been switched from the off-hook locking state to the on-hook state, the real-time port state corresponding to each of the N2 second network ports connected to the target communication cable may be further obtained. It should be noted here that the N2 second network ports are all or part of all the network ports connected by the target communication cable except the N1 first network ports. Then, the network device may obtain historical port states corresponding to each of the N2 second network ports. And determining whether the port state of each second network port is switched from the off-hook locking state to the on-hook state according to the historical port state corresponding to each second network port and the real-time port state corresponding to each second network port. If the network device determines that the port state of each second network port has been switched from the off-hook locked state to the on-hook state, it may be determined that the target communication cable is abnormal. Further, the network device may also output first alarm information indicating that the target communication cable is abnormal. If the network device determines that the port status of the N2 second network ports still remains in the off-hook locked state, it may be determined that the destination 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, the real-time port states of the N2 second network ports are continuously obtained, and whether the target communication cable is abnormal or not is further determined according to the real-time port states corresponding to the N2 second network ports, so that the occurrence of situations such as misjudgment caused by the abnormality of the port states of some first network ports can be avoided, and the accuracy of abnormality detection can be improved.

An optional implementation mode is five:

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

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

It can be understood here that, similar to the fourth embodiment, in a case that the abnormal parameter corresponding to the network port is the real-time port state of the network port and the xDSL service is carried on the target communication cable, the network device may first determine whether the port state of each first network port of the N1 first network ports is switched from the online state to the offline state. And if the network equipment determines that the port states of the first network ports are not all switched from the on-line state to the off-line state, determining that the target communication cable is normal. If the network device determines that the port states of the first network ports are all switched from the online state to the offline state, the real-time port states of the N2 second network ports connected with the target communication cable can be further obtained, and whether the target communication cable is abnormal or not is further judged according to the real-time port states of the N2 second network ports. Here, the specific determination process is similar to the above-described optional implementation, and is not described here again to avoid repetition. The mode of increasing the retest can also improve the accuracy of the anomaly detection.

It should be noted here that, in practical implementation, five implementations of the above-mentioned one to five implementations may also be used in combination with each other. For example, the network device may first perform a preliminary detection through the above-mentioned alternative implementation manner to obtain a first detection result. And then, performing second detection through the second optional implementation mode, the third optional implementation mode, the fourth optional implementation mode or the fifth optional implementation mode to obtain a second detection result. The network device may then determine whether the first detection result and the second detection result are the same. If the determination is the same, the first detection result may be determined as the final detection result. If the determination is not the same, one or more of the five alternative implementations described above may be performed again for anomaly detection. There are many possible combinations of the above five alternative implementations, and any combination of them is within the scope of the present application, and in order to avoid redundancy, the present application is not listed here.

In this embodiment, after determining the plurality of first network ports connected to the target communication cable, the network device directly determines whether the target communication cable is abnormal or not through real-time port states of the plurality of first network ports or measured values of electrical parameters between the first wires and the second wires connected to the first network ports. Therefore, an external detection system is not needed, and the abnormity detection cost can be reduced. In addition, the real-time port state of the network port or the measured value of the electrical parameter between the first conducting wire and the second conducting wire which are connected are all parameters which are easy to obtain by the network equipment, so that the complexity of the abnormity detection is simplified, and the efficiency of the abnormity detection can be improved.

Example two

Referring to fig. 5, fig. 5 is a schematic flow chart of a method for detecting an anomaly of a communication cable according to an embodiment of the present application. The method is also applicable to the communication system shown in fig. 1, and can also be executed by the network device in fig. 1, and the method for detecting an abnormality of a communication cable according to the present embodiment will also be described in detail in conjunction with the communication system shown in fig. 1. As shown in fig. 5, the method includes:

s501, the network device obtains an abnormality decision parameter corresponding to each third network port of the N1 third network ports of the network device.

In some possible implementations, after determining that anomaly detection of the communication cable is required, the network device may determine N1 third network ports from all of the network ports it includes. Here, N1 is a positive integer. Then, the network device may obtain the abnormality decision parameter corresponding to each third network port of the N1 second network ports. Here, the abnormality decision parameter corresponding to any one of the third network ports may include a real-time port state of any one of the third network ports or an actual measured value of an electrical parameter between the first conducting wire and the second conducting wire corresponding to the any one of the third network ports.

In specific implementation, when the network device determines that the preset detection trigger condition is satisfied, it may be determined that the anomaly detection of the communication cable needs to be performed. Here, the detection trigger condition may specifically be that a preset detection time arrives, or that an abnormality detection control instruction input by a user is received, and the present application is not limited to this specifically. The network device may then select N1 third network ports from all of the network ports to which it is connected. Here, the network device may randomly select N1 third network ports from all the network ports connected to the network device, the network device may also select the N1 network port for which the user equipment has fed back the abnormal information as N1 third network ports, the network device may also select the N1 third network ports by using other preset selection rules, and the method for the network device to select the N1 third network ports is not specifically limited in the present application. Then, the network device may obtain the abnormality decision parameter corresponding to each of the N1 third network ports. In this embodiment, the specific description of the abnormality decision parameter corresponding to each network port is consistent with the abnormality decision parameter corresponding to each network port in the first embodiment, so that the specific process of the network device acquiring the abnormality decision parameter corresponding to each third network port may refer to the process of the network device acquiring the abnormality decision parameter corresponding to each first network port described in step S202 in the first embodiment, and details thereof are not repeated here.

S502, the network device determines whether an abnormal target communication cable exists according to the abnormal judgment parameter corresponding to each third network port and the cable-network port incidence relation corresponding to the network device.

In some feasible implementation manners, after the network device obtains the abnormality decision parameter corresponding to each third network port, it may determine whether an abnormal target communication cable exists in the communication cables connected to the network device according to the abnormality decision parameter corresponding to each third network port and the cable-network port association relationship corresponding to the network device. Here, the cable-network port association corresponding to the network device indicates a communication cable to which each network port of the network device is connected.

The present embodiment provides a number of alternatives for determining whether an anomalous target communications cable is present, each of which is described in detail below.

The first optional implementation manner:

in this implementation manner, the abnormality decision parameter corresponding to each third network port is specifically an electrical parameter measured value between the first conducting wire and the second conducting wire corresponding to each third network port.

In a specific implementation, the network device may obtain the electrical parameter threshold range corresponding to each third network port. Here, for a specific process of the network device acquiring the electrical parameter threshold range corresponding to each third network port, reference may be made to the process of the network device acquiring the electrical parameter threshold range corresponding to each first network port described in step S203 in the foregoing embodiment, and details are not repeated here. Then, the network device may determine whether the measured value of the electrical parameter between the first conducting wire and the second conducting wire connected to each third network port is within the threshold range of the electrical parameter corresponding to each third network port.

On the other hand, if the network device determines that there are N2 fourth network ports in the N1 third network ports and the measured value of the electrical parameter between the first conducting wire and the second conducting wire connected to any one of the N2 fourth network ports is not within the electrical parameter threshold range corresponding to the any one of the fourth network ports, 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. If the network device determines that the N2 fourth network ports are simultaneously connected to the target communication cable, it may determine that an abnormal target communication cable exists.

In an alternative implementation manner, if the network device determines that the N2 fourth network ports are not simultaneously connected to the target communication cable, the current abnormality detection operation may be stopped, and it may be continuously determined whether the detection trigger condition is met.

In another alternative implementation, if the network device determines that the N2 fourth network ports are not simultaneously connected to the target communication cable, the network device may further determine at least two communication cables to which the N2 fourth network ports are connected. Then, the network device may perform the anomaly detection on the at least two communication cables respectively by using the anomaly detection method as described in the first embodiment.

In yet another optional implementation manner, if the network device determines that an abnormal target communication cable exists, second abnormal warning information may be output, where the second abnormal warning information is used to prompt that the target communication cable has an abnormality.

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

In the implementation manner, the network device determines whether an abnormal target communication cable exists through the measured value of the electrical parameter between the first wire and the second wire connected to each third network port, which can be directly measured, and the cable-network port corresponding relationship of the network device.

The second optional implementation mode:

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

In a specific implementation, the network device may obtain historical port states corresponding to the third network ports, where the historical port state corresponding to any third network port may be: before the anomaly detection, the port state of any third network port is obtained by detecting the port state of any third network port for the last time. Then, the network device may determine whether the port state of each first network port is switched from the off-hook locking 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 one hand, if the network device determines that the N1 third network ports include N2 fourth network ports according to the abnormality determination parameter corresponding to each third network port, and the port state of any one of the N2 fourth network ports has been switched from the off-hook locking state to the on-hook 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. It should be noted that, the network device determines 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, and the operation after the determining action is the same as the operation described in the first implementation manner, and the network device determines whether the N2 fourth network ports are simultaneously connected to the target communication cable and the operation after the determining action is the same, so that details are not described here to avoid repetition.

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 an off-hook locking state. Therefore, in order to make the historical port state of each third network port be the off-hook locking state, the first wire and the second wire connected with each third network port can be configured to be in a short-circuit state in advance.

In the implementation mode, in the scene that the communication cable of the network device carries the POST service, because the real-time port state of each network port is very easy to obtain and has good timeliness, the mode of determining whether the abnormal target communication cable exists or not based on the port state of the network port can ensure the accuracy and timeliness of the detection result, and the efficiency and the precision of the abnormal detection can be effectively improved while the abnormal detection cost is reduced.

The third optional implementation mode:

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

In specific implementation, the network device may also obtain a historical port state corresponding to each third network port. Then, the network device may determine whether the port state of each third network port is switched from the online state to the offline state according to the historical port state of each third network port and the obtained real-time port state corresponding to each third network port.

On one hand, if the network device determines that the N1 third network ports include N2 fourth network ports according to the abnormality determination parameter corresponding to each third network port, and the port status of any one fourth network port of the N2 fourth network ports has been switched from the online status to the offline status, 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 determining action is the same as the operation described in the above implementation manner, and the network device determines whether the N2 fourth network ports are simultaneously connected to the target communication cable and the operation after the determining action is the same, so that details are not described here again to avoid repetition.

On the other hand, if the network device determines that the port status of each of the N1 third network ports still remains on line, it may determine that there is no abnormal target communication cable. The network device may then proceed to determine whether the detection trigger condition is satisfied.

In the implementation manner, in a scenario that an xDSL service is carried on a communication cable of a network device, since the real-time port state of each network port is easily obtained and has good timeliness, the determination of whether an abnormal target communication cable exists based on the port state of the network port can ensure the accuracy and timeliness of the detection result, and the efficiency and precision of abnormality detection can be effectively improved while the abnormality detection cost is reduced.

It should be added here that, in practical implementation, the above-mentioned first alternative implementation and the second alternative implementation or the third alternative implementation may be used in combination with each other. For example, the network device may first perform a preliminary detection through the above-mentioned alternative implementation manner to obtain a first detection result. And then carrying out second detection through the optional implementation mode II to obtain a second detection result. The network device may then determine whether the first detection result and the second detection result are the same. If the determination is the same, the first detection result may be determined as the final detection result. If the determination is not the same, the above-mentioned detection action may be executed again. Here, there are various scenarios in which the first optional implementation manner is combined with the second optional implementation manner or the third optional implementation manner, where any scenario in which the first optional implementation manner is combined with the second optional implementation manner is within the scope of protection of the present application, and in order to avoid repetition, the scenarios are not listed here.

In this embodiment, the network device may determine N1 third network ports, and then quickly determine whether there is an abnormal target communication cable according to real-time port states of the N1 third network ports or measured values of electrical parameters between the first wires and the second wires connected to the respective third network ports, and a cable-network port association relationship of the network device. Therefore, an external detection system is not needed, and the abnormity detection cost can be reduced. In addition, the real-time port state of the network port or the measured value of the electrical parameter between the first conducting wire and the second conducting wire which are connected are all parameters which are easy to obtain by the network equipment, so that the complexity of the abnormity detection is simplified, and the efficiency of the abnormity detection can be improved.
