Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0026] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0027] In order to solve the problem of low efficiency of fault location of communication units in the prior art, the present application provides a fault detection location, such as Figure 1 As shown, the steps of the method include:

[0028] Step 101: Acquire a fault information signal of each communication unit in the system, wherein the system includes multiple communication units, and the fault information signal indicates whether the corresponding communication unit is in a fault state or a normal state;

[0029] It should be noted that the system usually includes multiple communication units, and the multiple communication units have logical relationships with each other. Figure 2 As shown, the communication path of the communication unit in the system is that the bottom communication unit sends a communication signal to the high-level communication unit through the physical connection unit, and the bottom communication unit may include one or more communication units, and the high-level communication unit may also include one or more communication units. Figure 3 As shown, under normal circumstances, the signal is sent by the lowest communication unit in the bottom communication unit to the upstream communication unit in the bottom communication unit. If the bottom communication unit has multiple communication units, the signal is transmitted to the upstream communication unit layer by layer. After being transmitted to the physical connection unit, the physical connection unit sends a signal to the high-level communication unit. The top-level communication unit in the high-level communication unit receives the signal first, and then transmits it to the corresponding upstream communication unit, and finally transmits it to the highest-level communication unit in the high-level communication unit, and finally transmits it outward by the highest-level communication unit.

[0030] In addition, in a specific example, the fault information signal in the embodiment of the present application can be represented by a binary number, such as the binary number "1" indicates that the communication unit is in a fault state, and the binary number "0" indicates that the communication unit is in a normal state.

[0031] Step 102: extracting a portion of target fault information signals from the plurality of fault information signals;

[0032] Typically, this target fault information signal refers to the highest-level communication unit in the faulty high-level communication units, the lowest-level communication unit that communicates with it, and then the upstream communication unit of that lowest-level communication unit. Based on these three communication units, the fault location can be quickly determined. Since data is transmitted from the bottom layer to the upper layer, after first determining the faulty highest-level communication unit, the corresponding faulty lowest-level communication unit and upstream communication unit are determined downwards. This allows for rapid identification of the fault location within the communication link, or between two communication units.

[0033] It should be noted that in other specific examples, the number of partial target fault information signals is three, which has a good fault location effect. To more accurately locate the fault location or type, the number of partial target fault information signals can be set to more than three. However, in fact, the location accuracy of three or more target fault information signals is not much different. Therefore, in order to achieve faster fault location, three target fault information signals are usually selected.

[0034] Step 103 , matching part of the target fault information signal with a preset table, and determining the fault type or fault location of the communication unit in the system based on the matching result; wherein the preset table includes multiple target fault information signal combinations, and each combination corresponds to a fault type or fault location.

[0035] In a specific example, if there are three partial target fault information signals, and the target fault information signals are represented by binary numbers, the corresponding preset table includes multiple binary number combinations (target fault information signal combinations), each of which includes three binary digits, such as one group of binary digits being 111 (one group of target fault information signal combinations), another group of digits being 110 (another group of target fault information signal combinations), and so on. Each group of binary digits corresponds to a group of fault information signals, indicating the location or type of the fault, and may also indicate that the communication unit is operating normally. It can be seen that fault location in the embodiments of the present application can be used to locate both the fault location and the fault type.

[0036] Through the above steps 101 to 103, in an embodiment of the present application, the fault information signal of each communication unit in the system is obtained, and then part of the target fault information signal is extracted from the multiple fault information signals, and the part of the target fault information signal is matched with the preset table, and the fault type or fault location of the communication unit in the system is determined according to the matching result. It can be seen that by collecting the fault information signal and comparing the collected result with the preset table, the type or location of the current fault can be quickly determined. Compared with the prior art method of performing fault diagnosis by comparing the actual alarm signals one by one, in the present application, the fault location efficiency is higher by extracting part of the target fault information signal and then comparing it with the preset table.

[0037] In the embodiment of the present application, since the communication unit usually has only two states during operation, one is normal operation and the other is a fault state. Therefore, in order to be able to intuitively describe the operating state of the communication unit, the operating state of the communication unit can be represented by a binary number, such as the binary number 1 represents that the communication unit is in a fault state, and the binary number 0 represents that the communication unit is in a normal state. That is to say, during the operation of the communication unit, if it is currently necessary to obtain the fault information signal of the communication unit, the communication unit determines the corresponding binary number based on the current actual operating state, and the state of the communication unit can be quickly determined based on the binary number. Therefore, the method of obtaining the fault information signal of each communication unit in the system involved in step 101 in the embodiment of the present application can further include:

[0038] Step 11: Obtain the binary numbers sent by each communication unit of the system, wherein the binary numbers are fault information signals, and when the binary number is 1, it indicates that the corresponding communication unit is in a fault state, and when the binary number is 0, it indicates that the corresponding communication unit is in a normal state;

[0039] Step 12: setting the position of the binary digit according to the position of the communication unit in the system to obtain a fault information signal of the system.

[0040] In this regard, in a specific example, if there are 9 communication units in the current system, and the binary number determined by each communication unit based on its corresponding operating state is as follows: the binary number corresponding to the 0th communication unit is "0", the binary number corresponding to the 1st communication unit is "0", the binary number corresponding to the 2nd communication unit is "1", the binary number corresponding to the 3rd communication unit is "0", the binary number corresponding to the 4th communication unit is "0", the binary number corresponding to the 5th communication unit is "0", the binary number corresponding to the 6th communication unit is "1", the binary number corresponding to the 7th communication unit is "1", and the binary number corresponding to the 8th communication unit is "1", then the binary numbers of the fault information signals obtained by the corresponding 9 communication units from the 0th to the 8th communication unit are: 001000111. From this series of binary numbers, it is possible to quickly determine whether the current operating state of each communication unit is normal operation or a fault state.

[0041] In an embodiment of the present application, the partial target fault information signal refers to the highest-level communication unit in the high-level communication unit where the fault occurs, and the lowest-level communication unit that communicates with the highest-level communication unit, and then the upstream communication unit of the lowest-level communication unit. Based on these three communication units, the location of the fault can be quickly determined. That is to say, the number of partial target fault information signals in the embodiment of the present application is usually 3. If more accurate positioning is required, it can be more than 3, but the positioning efficiency is inversely proportional to the number of target fault information signals. Based on the fact that the number of partial target fault information signals is 3, the method of extracting partial target fault information signals from multiple fault information signals involved in the above step 102 of the present application is further explained below. Therefore, the step 102 may further include:

[0042] Step 21, determining a communication unit in a fault state from a plurality of fault information signals;

[0043] Step 22: extract the fault information signals of the highest layer communication unit, the lowest layer communication unit communicating with the highest layer communication unit, and the upstream communication unit of the lowest layer communication unit from the communication unit in the fault state and determine them as part of the target fault information signals.

[0044] As can be seen, in the embodiment of the present application, the target fault information signals that ultimately need to be determined are the fault information signals of the highest-level communication unit, the lowest-level communication unit, and the upstream communication unit of the lowest-level communication unit. When there are many communication units, the fault information signals of these three can be used to quickly locate the fault, that is, to locate both the fault location and the fault type.

[0045] It can be seen that the method involved in step 22 above of extracting target fault information signals of the highest-level communication unit, the lowest-level communication unit communicating with the highest-level communication unit, and the upstream communication unit of the lowest-level communication unit from the communication unit in the faulty state may further include:

[0046] Step 31: When the number of communication units in a faulty state is one, determine the fault information signals of any two communication units among the target fault information signals of the communication unit in the faulty state, the highest-level communication unit in the combined system, the lowest-level communication unit communicating with the highest-level communication unit, and the upstream communication unit of the lowest-level communication unit as partial target fault information signals;

[0047] In this regard, in a specific example, if there is only one communication unit that currently fails, this communication unit may be any communication unit. If it is the highest-level communication unit, then in this application, it is also necessary to determine the fault information signals of the corresponding lowest-level communication unit and the corresponding upstream communication unit as the target fault information signal of this part.

[0048] Step 32, when the number of communication units in a faulty state is greater than or equal to 2, the fault information signals of the highest-level communication unit, the lowest-level communication unit that communicates with the highest-level communication unit among the communication units in a faulty state, and the upstream communication unit of the lowest-level communication unit are extracted from the communication units in a faulty state and determined as partial target fault information signals.

[0049] In this specific example, let's assume there are nine communication units and the corresponding binary number of the fault information signal is 001000111. Among the faulty communication units, the highest-level communication unit is selected, i.e., the eighth communication unit. The lowest-level communication unit that communicates with the eighth communication unit and has also failed is found, i.e., the second communication unit. Then, the upstream communication units of this lowest-level communication unit are determined, i.e., the three communication units.

[0050] In this regard, in an embodiment of the present application, the method of matching multiple target fault information signals with a preset table in the above step 103 and determining the fault type of the communication unit in the system according to the matching result may further include:

[0051] Step 41, determining a target digital combination corresponding to the fault information signal of the highest layer communication unit, the fault information signal of the lowest layer communication unit, and the fault information signal of the upstream communication unit;

[0052] Step 42: Match a number combination that matches the target number combination from a preset table, and determine the fault type or fault location in the system according to the matched number combination.

[0053] In this regard, in a specific example, the preset table may be as follows:

[0054]

[0055] Table 1

[0056] Among them, C represents the signal corresponding to the lowest-level communication unit, B represents the signal corresponding to the upstream communication unit, and A represents the signal corresponding to the highest-level communication unit.

[0057] It can be seen from this that if the binary number combination corresponding to the currently determined partial fault information signal is 111, it means that a fault has occurred in the bottom-level communication unit. If the binary number combination is 110, it means that the fault information signal corresponding to the highest-level communication unit is wrong, because the bottom layer before the highest layer and the corresponding upstream unit are reporting faults, but when it comes to the high-level communication unit, it is indeed normal. Therefore, the fault information signal corresponding to the high-level communication unit at this time is wrong, and it is necessary to further determine which communication unit has a problem based on the specific situation.

[0058] It should be noted that, in the embodiment of the present application, when the fault location is identified, it is necessary to delete the faulty communication unit and the corresponding fault information signal so that the communication in the current system can still operate normally.

[0059] The present application is explained below in conjunction with the specific implementation of the embodiment of the present application. The specific implementation provides a method for locating a fault in a communication module, such as Figure 4 As shown, the steps of the method include:

[0060] Step 401: extract the binary numbers A(k), B(k), and C(k) corresponding to the fault information signal.

[0061] Step 402: Match the extracted binary number combination with the rules in Table 1.

[0062] Step 403: Determine the specific location or type of the fault based on the matching result.

[0063] In this regard, in a specific application scenario, the extracted fault information signal combination is: 111000100, which is a 9-bit binary number, each bit represents the alarm signal status of a communication unit. Specifically:

[0064] Bit 0: 0 → The 0th communication unit is normal

[0065] Bit 1: 0 → The first communication unit is normal

[0066] 2nd bit: 1 → 2nd communication unit failure

[0067] Bit 3: 0 → The third communication unit is normal

[0068] Bit 4: 0 → The 4th communication unit is normal

[0069] Bit 5: 0 → The 5th communication unit is normal

[0070] Bit 6: 1 → The 6th communication unit is faulty

[0071] Bit 7: 1 → The 7th communication unit is faulty

[0072] Bit 8: 1 → The 8th communication unit is faulty

[0073] Determine the highest-level communication unit. Among the failed communication units, select the one at the highest level, which is the eighth communication unit. Then, find the corresponding communication unit, which is the second communication unit. Normally, the zeroth communication unit should be the lowest-level communication unit, but both the zeroth and first communication units are functioning normally. Therefore, find the first failed communication unit as the lowest-level communication unit. The upstream communication unit of the second communication unit is the third communication unit.

[0074] Extract A(k)=1 from the first unit Y (the 8th communication unit).

[0075] Extract C(k)=1 from the second unit X (the second communication unit).

[0076] Extract B(k)=0 from the third unit Z (the 3rd communication unit).

[0077] The combined fault information signal is C(k)=1, B(k)=0, A(k)=1. Combining Table 1, it can be seen that the corresponding judgment result is the error B signal.

[0078] As can be seen, by combining the combination of fault information signals with the rules in Table 1, the system can efficiently locate faults without having to pre-store all possible fault propagation modes. Furthermore, this method significantly reduces storage requirements and increases the speed of fault location, making it particularly suitable for large-scale hierarchical communication networks.

[0079] Corresponding to the above Figure 1 , the embodiment of the present application also provides a fault detection device, such as Figure 5 As shown, the device includes:

[0080] An acquisition module 502 is configured to acquire a fault information signal of each communication unit in the system, wherein the system includes multiple communication units, and the fault information signal indicates whether the corresponding communication unit is in a fault state or a normal state;

[0081] An extraction module 504 is configured to extract a portion of target fault information signals from the plurality of fault information signals;

[0082] The first processing module 506 is used to match part of the target fault information signal with a preset table and determine the fault type or fault location of the communication unit in the system based on the matching result; wherein the preset table includes multiple target fault information signal combinations, and each combination corresponds to a fault type or fault location.

[0083] Through the device of the embodiment of the present application, the fault information signal of each communication unit in the system is obtained, and then some target fault information signals are extracted from the multiple fault information signals, and the some target fault information signals are matched with the preset table, and the fault type or fault location of the communication unit in the system is determined according to the matching result. It can be seen that by collecting the fault information signal and comparing the collected result with the preset table, the type or location of the current fault can be quickly determined. Compared with the prior art method of performing fault diagnosis by comparing the actual alarm signals one by one, in the present application, the fault location efficiency is higher by extracting some target fault information signals and then comparing them with the preset table.
