[0002] Cable testers are commonly used tools in the network cabling process. Cable finders can find cables, and cable alignment instruments can test the connectivity of each core in the cable in turn, and determine whether there is a problem with the cable based on the test results.

[0003] In actual applications, the cable testers on the market are generally used independently as cable finders and cable alignment instruments. Operators need to carry multiple instruments, manually operate the cable finder to find the cables, then put it aside and use the cable alignment instrument instead, and then manually operate the cable alignment instrument to align the wire cores.

[0004] In order to solve the inconvenience of having to carry multiple instruments for line search and line matching, there are now devices with integrated line search and line matching functions on the market. However, if you want to switch from the line search function to the line matching function, the operator still needs to search along the network cable from the transmitter, and find the other end of the network cable (often at the network cable box at the entrance or the switch in the computer room), and then return to the transmitter to manually unplug it from the line search interface, and then insert it into the line matching interface to switch the line search function to the object function. Practice has found that it is very inconvenient to switch functions by manually operating the machine, the line search and line matching efficiency is low, and it is easy to make mistakes in line search and line matching.

The following is a detailed description of the method and device for realizing line search and alignment applied to multifunctional cable maintenance equipment.

[0084] Embodiment 1

[0085] See also Figure 1 , Figure 1 The present invention discloses a method for realizing line search and pairing in a multifunctional cable maintenance device. Figure 1 The described method for line finding and line matching applied to a multifunctional cable maintenance device can be implemented by a multifunctional cable maintenance device, wherein the multifunctional cable maintenance device includes a transmitter and a receiver, wherein the transmitter and the receiver communicate via a cable (also called a cable), and the cable is composed of a plurality of wire cores. The transmitter and the receiver can be integrated into one multifunctional cable maintenance device, or can be separated into two devices, that is, the multifunctional cable maintenance device can be composed of two devices, a transmitter and a receiver. Furthermore, the transmitter (also called a transmitter) can be understood as a host or a host computer, and the receiver (also called a receiver) can be understood as a slave or a slave computer. Furthermore, the types of all wire cores can be only twisted pair types, or can be twisted pair types and shielded wire types, wherein when two types are included, the number of wire cores corresponding to the twisted pair type is not less than the number of wire cores corresponding to the shielded wire type. Figure 1 As shown, the line-finding and line-pairing implementation method applied to the multifunctional cable maintenance device may include the following operations:

[0086] 101. After the transmitter starts the line-finding function, the transmitter transmits a line-finding signal to the receiver through all line cores, and transmits a handshake signal to the receiver in the interval between transmitting the line-finding signal. The handshake signal is used for the transmitter and the receiver to perform a handshake operation.

[0087] In an embodiment of the present invention, the line-finding signal is used to find all the wire cores between the transmitting end and the receiving end, and the transmitting end transmits the line-finding signal to the receiving end through all the wire cores. Specifically: the internal timer of the microcontroller of the transmitting end outputs a specific coded modulation signal as the line-finding signal of the transmitter through multiple pins (such as GPIO pins) of the microcontroller, and the microcontroller controls the single-pole double-throw analog switch array to keep the line-finding signal output simultaneously. The line-finding signal is connected to the cable through the RJ45 interface after passing through the protection circuit. The line-finding signal is simultaneously output to each wire core in the cable to ensure that the measured cable has at least one internal core connected so that the receiving end can receive the line-finding signal to find the corresponding wire core and the receiving end. Optionally, the line-finding signal may not be periodic, or may have a signal period, that is, only one or two line-finding signals are sent in one period to ensure that the line-finding signal is completely transmitted. And optionally, a line-finding signal of multiple periods can be transmitted, which can reduce the failure of the receiver to successfully receive the line-finding signal due to special circumstances (such as network instability), improve the success rate of the receiver receiving the line-finding signal, and thus help improve the success rate of achieving line-finding. It should be noted that, no matter whether the line search signal is transmitted in one cycle or in multiple cycles, the handshake signal is transmitted in the interval between the transmission of the line search signal (which can also be understood as at the same time). Figure 2 As shown, Figure 2 The present invention discloses a schematic diagram of transmitting a handshake signal in the gap between transmitting a line search signal and detecting that the receiving end replies to the handshake signal. Figure 2 As shown, the transmitting end (device) transmits a handshake signal in the interval of transmitting the line-finding signal. When a handshake reply signal from the receiving end (device) is detected, that is, a reply response to the handshake signal, it is determined that the handshake between the transmitting end and the receiving end is successful, and the mode is switched to the line-matching mode to transmit the line-matching signal to the receiving end.

[0088] 102. The transmitting end detects a first response result of the receiving end to the handshake signal, and determines whether the transmitting end has successfully handshaked with the receiving end according to the first response result.

[0089] 103. When it is determined that the transmitter and the receiver have successfully handshaked, the transmitter switches the current working mode of the transmitter from the line-finding mode to the line-matching mode, and performs line-matching interaction with the receiver in the line-matching mode to obtain a line-matching result.

[0090] In the embodiment of the present invention, the line-finding function and the line-aligning function share an RJ45 network cable interface. The transmitter switches the current working mode of the transmitter from the line-finding mode to the line-aligning mode.

[0091] In an embodiment of the present invention, optionally, after finding the cable according to the line-finding signal, the cable can be automatically inserted into the line-matching interface of the receiving end through the device, or the line-finding signal can be filtered, demodulated, and amplified in sequence by the receiving end, and the amplified line-finding signal is sent to the microcontroller of the receiving end. The microcontroller of the receiving end outputs the alarm audio to the power amplifier chip, driving the speaker to emit an alarm sound, so that the operator can insert the cable into the line-matching interface of the receiving end.

[0092] It can be seen that after the transmitter starts the line-finding function when implementing the embodiment of the present invention, the transmitter transmits a line-finding signal to the receiver through all line cores, and in the intervals between transmitting the line-finding signal, transmits a handshake signal to the receiver to request a handshake with the receiver; when it is detected that the handshake between the transmitter and the receiver is successful, the transmitter automatically switches the current working mode of the transmitter from the line-finding mode to the line-aligning mode, and performs line-aligning interaction with the receiver in the line-aligning mode to obtain a line-aligning result, thereby improving the efficiency and accuracy of line-finding and line-aligning, and there is no need for manual line-finding and line-aligning operations on the transmitter and the receiver, thereby improving the convenience of line-finding and line-aligning.

[0093] In the embodiment of the present invention, optionally, the transmitting end transmits a handshake signal to the receiving end in a gap between transmitting the line search signal, including:

[0094] The transmitting end determines at least one first wire core from all the wire cores for transmitting a handshake signal;

[0095] In the interval of transmitting the line search signal, the transmitting end transmits a handshake signal to the receiving end through at least one first line core according to a first preset transmission mode, and the first preset transmission mode includes a simultaneous transmission mode or a one-by-one transmission mode.

[0096] In the embodiment of the present invention, optionally, at least one first core may be all selected cores or some selected cores. When some cores are selected, they may be randomly selected or deliberately selected without limitation. Further optionally, when the first preset transmission mode is a simultaneous transmission mode, as long as a response sent by the receiving end is received on one core, it indicates that the transmitter and the receiver have successfully handshaked; when the first preset transmission mode is a one-by-one transmission mode, if a response sent by the receiving end is not received on the current core, a handshake signal is transmitted through the next core, but as long as a response sent by the receiving end is received on the current core, it indicates that the transmitter and the receiver have successfully handshaked, and there is no need to transmit handshake signals through the remaining selected cores.

[0097] In an embodiment of the present invention, each of the multiple pins of the microcontroller at the transmitting end corresponds one-to-one to each of the multiple pins of the microcontroller at the receiving end, and each wire core is connected one-to-one to the pin of the microcontroller at the transmitting end and its corresponding pin of the microcontroller at the receiving end. For example, there are two wire cores Line1, Line2, and Line3, two pins A1, A2, and A3 of the microcontroller at the transmitting end, and two pins B1, B2, and B3 of the microcontroller at the receiving end, and A1 corresponds to B1, A2 corresponds to B2, and A3 corresponds to B3, then Line1 is connected between A1 and B1, Line2 is connected between A2 and B2, and Line3 is connected between A3 and B3. Figure 3 is a schematic diagram of transmitting a handshake signal in a one-by-one transmission manner disclosed in an embodiment of the present invention, Figure 4 is a schematic diagram of transmitting a handshake signal in a one-by-one manner and detecting a response of a receiving end to the handshake signal disclosed in an embodiment of the present invention, such as Figure 3 , 4 As shown, the transmitter transmits a handshake signal w0 to the receiver through the line cores Line1, Line2, and Line3 one by one. After the transmitter sends the handshake signal w0, it immediately switches to the receiving mode. If the receiver does not receive a response (reply) to the handshake signal from the receiver through the line core Line1 at this time, it continues to transmit the handshake signal to the receiver through Line2. At this time, the receiver receives a response (reply) to the handshake signal from the receiver through the line core Line2, that is, it replies with an equivalent signal w1. There is no need to transmit a handshake signal to the receiver through Line3, and it is determined that the handshake with the receiver is successful.

[0098] It can be seen that the embodiments of the present invention can achieve the successful transmission of handshake signals by transmitting handshake signals to all or part of the line cores simultaneously or one by one to the receiving end; and by selecting part of the line cores to transmit handshake signals, while ensuring that the feedback of the receiving end is received after the handshake signal is successfully transmitted, the time of the handshake stage is saved while ensuring the successful handshake with the receiving end, which is conducive to further improving the line alignment efficiency; and by selecting all the line cores to transmit handshake signals, it can reduce the occurrence of failure to successfully transmit handshake signals due to the presence of broken line cores inside the network cable with good appearance, and reduce the possibility of failure to handshake due to the presence of broken line cores, thereby improving the reliability of the successful handshake between the transmitting end and the receiving end, which is conducive to improving the reliability of switching to the line alignment function, and then conducive to further improving the probability of successfully completing the line alignment.

[0099] In the embodiment of the present invention, optionally, the transmitting end performs online interaction with the receiving end in the online mode to obtain an online result, including:

[0100] In the alignment mode, the transmitter sends an alignment start signal (such as w2) to the receiver, monitors the falling edge of the alignment start signal, and determines the target timing corresponding to the transmitter according to the falling edge of the alignment start signal;

[0101] The transmitter transmits the pairing signal to the receiver through all the line cores based on the target timing and the interface line sequence of each line core and the pairing line interface of the transmitter;

[0102] The transmitting end detects a second response result of the receiving end to the line signal, the second response result including a response signal made by the transmitting end to the line signal, a timing sequence of the response signal and a line sequence of the response signal;

[0103] The transmitting end determines the alignment result between the transmitting end and the receiving end according to the second response result, the target timing sequence, and the interface line sequence, wherein the alignment result includes the alignment result of the transmitting end.

[0104] In the embodiment of the present invention, the line alignment result between the transmitting end and the receiving end includes one of a connected open line result, a short line result, a non-connected short line result, a straight-through line result, and a cross line result.

[0105] Among them, the connected open line result is used to indicate that all the cores between the transmitter and the receiver are in an open circuit state, the short line result is used to indicate that there are cores in a short circuit state and no open circuit among all the cores between the transmitter and the receiver, the non-connected short line result is used to indicate that all the cores between the transmitter and the receiver are in an open circuit and short circuit state, the straight-through line result is used to indicate that all the cores between the transmitter and the receiver are in a connected state (i.e., not short-circuited or disconnected) and the line sequence of each core on the transmitter corresponds to the line sequence on the receiver, and the cross line result is used to indicate that all the cores between the transmitter and the receiver are in a connected state (i.e., not short-circuited or disconnected) and there are cores whose line sequence on the transmitter and the line sequence on the receiver do not correspond one to one.

[0106] In an embodiment of the present invention, optionally, the interactive mode in which the transmitter and the receiver exchange alignment information is master-slave pseudo-duplex. After transmitting the alignment start signal (such as w2) to the receiver, both the transmitter and the receiver use the falling edge of the alignment start signal (such as w2) as the starting time point of the alignment (i.e., the target timing). Optionally, starting from the alignment start time point, the preset time length can be delayed backward, and the transmitter transmits the alignment signal fd1 to all the cores to the receiver one by one or simultaneously, wherein for simultaneous transmission, the alignment signal corresponding to each core is also different, and for one-by-one transmission, the alignment signal corresponding to each core can be the same or different. Similarly, after the transmitting end transmits the corresponding alignment signal, it immediately switches to the input (receiving) mode, specifically, the pin of its microcontroller switches to the input (receiving) mode to receive the second response result of the receiving end to the alignment signal, specifically the response signal jd1 with the same width as the alignment signal fd1, the timing of the response signal and the line sequence of the response signal, and determines the alignment result between the transmitting end and the receiving end according to the received second response result and the target timing and interface line sequence, wherein the second response result includes the response result of each wire core. Optionally, the alignment result between the transmitting end and the receiving end is determined by further combining the identification of all the second wire cores obtained in the embodiment of the present invention. Among them, the transmitting end determines the alignment result between the transmitting end and the receiving end according to the received second response result and the target timing, the interface line sequence and the identification of all the second wire cores obtained in the embodiment of the present invention, specifically including:

[0107] If the identifiers of all the second cores obtained according to the embodiment of the present invention determine that all the cores between the transmitting end and the receiving end are not in a short-circuit state and the received second response result is used to indicate that no response from any core is received, then it is determined that the line alignment result between the transmitting end and the receiving end is a connected open line result;

[0108] If the identifiers of all the second cores obtained according to the embodiment of the present invention determine that there is a core in a short-circuited state among all the cores between the transmitting end and the receiving end, and the received second response result is used to indicate that the responses of all the cores are received but the timing of the response signals corresponding to at least two cores among all the cores are the same, then it is determined that the alignment result between the transmitting end and the receiving end is a short-circuited line result;

[0109] If the identifiers of all the second cores obtained according to the embodiment of the present invention determine that all the cores between the transmitting end and the receiving end are in a short-circuit state and the received second response result is used to indicate that no response from any core is received, then it is determined that the line alignment result between the transmitting end and the receiving end is a non-connected short-circuit line result;

[0110] If it is determined according to the identifications of all the second cores obtained in the embodiment of the present invention that all the cores between the transmitting end and the receiving end are not in a short-circuit state and the received second response result is used to indicate that the responses of all the cores are received and the timing of the response signal corresponding to each core matches the target timing and the line sequence of the response signal corresponds to the interface line sequence one by one (such as B1 to A1, B2 to A2), then it is determined that the line alignment result between the transmitting end and the receiving end is a straight-through line result;

[0111] If it is determined according to the identification of all the second cores obtained in the embodiment of the present invention that all the cores between the transmitting end and the receiving end are not in a short-circuit state and the received second response result is used to indicate that the responses of all the cores have been received but there are cores among all the cores whose timing of the response signal matches the target timing and the line sequence of the response signal does not correspond to the interface line sequence (such as B1 to A2, B2 to A1), then it is determined that the line alignment result between the transmitting end and the receiving end is a cross-line result.

[0112] In the embodiment of the present invention, further optionally, the alignment result also includes the alignment result of the receiving end. The type of the alignment result of the receiving end is the same as the type of the alignment result of the transmitting end, and after receiving the handshake signal transmitted by the transmitting end, the receiving end determines its corresponding alignment result according to the determination method of the alignment result of the transmitting end. For details, see the determination process of the alignment result of the transmitting end, which will not be repeated here.

[0113] In the embodiment of the present invention, further optionally, the obtained alignment result is displayed through a display module (such as a liquid crystal display screen).

[0114] It can be seen that in the alignment mode, the embodiment of the present invention first transmits an alignment start signal to the transmitting end so that the receiving end knows that it is ready to align the line, and uses the falling edge of the alignment start signal as a unified timing to transmit the alignment signal to the receiving end, and combines the feedback response model received from the receiving end, the timing of the response signal and the corresponding line sequence with the interface line sequence and the unified timing when it is transmitted, and performs alignment analysis on the line core between the transmitting end and the receiving end, which can achieve accuracy and reliability of the alignment analysis and obtain accurate and reliable alignment results.

[0115] In the embodiment of the present invention, optionally, the transmitting end determines whether the handshake between the transmitting end and the receiving end is successful according to the first response result, including:

[0116] When the response right of the handshake signal belongs solely to the receiving end, the transmitting end determines whether the first response result is used to indicate that the transmitting end has received a response corresponding to the handshake signal, and when the result is yes, it is determined that the handshake between the transmitting end and the receiving end is successful;

[0117] When the response authority of the handshake signal does not belong solely to the receiving end, the transmitting end determines whether the first response result is used to indicate that the transmitting end has received a response corresponding to the handshake signal and the identifier of the response matches the identifier of the receiving end. When the judgment result is yes, it is determined that the handshake between the transmitting end and the receiving end is successful.

[0118] In an embodiment of the present invention, optionally, the response authority of the handshake signal belongs solely to the receiving end, indicating that only the receiving end can respond to the handshake signal, and other devices (such as computers and switches) cannot respond to the handshake signal. The response authority of the handshake signal does not belong solely to the receiving end, indicating that the receiving end and other devices (such as computers and switches) can respond to the handshake signal, but the response identifiers for the handshake signal are different. For example, the response identifier made can be carried on the response to the handshake signal. The transmitting end can determine that the receiving end has received and responded to the handshake signal through the response identifier (such as type) carried on the response, thereby shaking hands with it.

[0119] In the embodiment of the present invention, optionally, when the result of the determination is negative, the above step 101 is executed again.

[0120] It can be seen that the embodiment of the present invention selects different methods to determine the success of handshake with the receiving end through the ownership authority of the handshake signal, which can improve the accuracy and reliability of determining the success of handshake between the transmitting end and the receiving end, thereby facilitating improving the accuracy of switching to the line mode for line connection.

[0121] In an optional embodiment, the method may further include the following steps:

[0122] The transmitting end transmits a short circuit self-detection signal corresponding to each wire core to each of the wire cores in all the wire cores according to a second preset transmission mode;

[0123] For any wire core, after transmitting the short-circuit self-test signal corresponding to the wire core, the transmitting end determines whether there is a second wire core that reads the short-circuit self-test signal among all the remaining wire cores except the wire core. When the result of the judgment is yes, the second wire core is selected from all the remaining wire cores, and the identification of the second wire core is recorded. The identification of the second wire core is used as the basis for determining the line alignment result.

[0124] In this optional embodiment, when the second preset transmission mode is a simultaneous transmission mode, the types of short-circuit self-test signals corresponding to all the cores are different from each other; when the second preset transmission mode is a one-by-one transmission mode, the types of short-circuit self-test signals corresponding to all the cores are different from each other or the types of short-circuit self-test signals corresponding to all the cores are the same. Specifically, for transmitting the same type of short-circuit self-test signals, the microcontroller at the transmitting end sends a short-circuit self-test signal (such as a short pulse d) to each core of the cable port one by one. For any core, after sending the short-circuit self-test signal, it is determined whether there is a second core in the remaining cores that can read the short-circuit self-test signal. If so, it is determined that the second core is short-circuited, and the identification (such as the serial number) of the second core is recorded.

[0125] In this optional embodiment, optionally, when the result of the judgment is no, the above step 101 is triggered to be executed.

[0126] It can be seen that this optional embodiment helps to improve the accuracy and reliability of subsequent line alignment by performing short-circuit self-checks on the wire cores at the transmitting end and recording all short-circuited wire cores; and by transmitting different types of short-circuit self-check signals simultaneously or one by one, or transmitting the same type of short-circuit self-check signals one by one, it provides a variety of short-circuit self-check signal sending methods, which can improve the flexibility of short-circuit self-check signal sending, thereby helping to improve the efficiency of judging wire core short circuits.

[0128] See also Figure 5 , Figure 5 This is a flow chart of another method for realizing line search and pairing in a multifunctional cable maintenance device disclosed in an embodiment of the present invention. Figure 5 The described line-finding and line-pairing implementation method applied to a multifunctional cable maintenance device can be implemented by the multifunctional cable maintenance device, which includes a transmitter and a receiver, wherein the transmitter and the receiver communicate via a cable (also called an electric cable), and the cable is composed of multiple wire cores. Among them, the types of all wire cores can be only twisted pair types, or can be twisted pair types and shielded wire types, wherein, when two types are included, the number of wire cores corresponding to the twisted pair type is not less than the number of wire cores corresponding to the shielded wire type. Figure 5 As shown, the line-finding and line-pairing implementation method applied to the multifunctional cable maintenance device may include the following operations:

[0129] 201. After the transmitting end starts the line search function, the transmitting end determines the current configuration information of the multifunctional cable maintenance device.

[0130] 202. The transmitting end determines whether the current configuration state of the multifunctional cable maintenance device meets the line search and pair start condition according to the current configuration information of the multifunctional cable maintenance device.

[0131] 203. When the result of the judgment is yes, the transmitting end transmits a line-finding signal to the receiving end through all line cores, and transmits a handshake signal to the receiving end in the interval between transmitting the line-finding signal, wherein the handshake signal is used for the transmitting end and the receiving end to perform a handshake operation.

[0132] 204. The transmitting end detects a first response result of the receiving end to the handshake signal, and determines whether the transmitting end has successfully handshaked with the receiving end according to the first response result.

[0133] 205. When it is determined that the transmitter and the receiver have successfully handshaked, the transmitter switches the current working mode of the transmitter from the line-finding mode to the line-matching mode, and performs line-matching interaction with the receiver in the line-matching mode to obtain a line-matching result.

[0134] It should be noted that, for other related descriptions of step 203 to step 205, please refer to other descriptions of step 101 to step 103 in embodiment 1, and this embodiment of the present invention will not be repeated here.

[0135] It can be seen that after the transmitter starts the line-finding function in the implementation of the embodiment of the present invention, the transmitter transmits a line-finding signal to the receiver through all the line cores, and transmits a handshake signal to the receiver in the interval between the transmission of the line-finding signal to request a handshake with the receiver; when it is detected that the handshake between the transmitter and the receiver is successful, the transmitter automatically switches the current working mode of the transmitter from the line-finding mode to the line-matching mode, and performs line-matching interaction with the receiver in the line-matching mode to obtain a line-matching result, thereby improving the efficiency and accuracy of line-finding and line-matching, and there is no need to manually perform line-finding and line-matching operations on the transmitter and the receiver, thereby improving the convenience of line-finding and line-matching. In addition, before performing line-finding and line-matching, the current configuration information of the transmitter and / or the current configuration information of the receiver is first analyzed, and the subsequent line-finding and line-matching operations are performed only after the corresponding line-finding and line-matching start conditions are met, which can improve the execution accuracy and reliability of the operation, thereby improving the success probability and efficiency of line-finding and line-matching.

[0136] In the embodiment of the present invention, optionally, the current configuration information of the multifunctional cable maintenance device includes the current configuration information of the transmitting end and / or the current configuration information of the receiving end;

[0137] The transmitting end determines whether the current configuration state of the multifunctional cable maintenance device meets the line search and line start condition according to the current configuration information of the multifunctional cable maintenance device, including:

[0138] When the current configuration information of the multifunctional cable maintenance device includes the current configuration information of the transmitting end, the transmitting end determines whether the pair-finding line interface of the transmitting end is connected to the multiple pins of the microcontroller of the transmitting end through its corresponding overvoltage and overcurrent protection circuit and / or analog switch. When the result of the determination is yes, it is determined that the current configuration state of the multifunctional cable maintenance device meets the pair-finding line start condition, and the multiple pins of the microcontroller of the transmitting end include multiple GPIO pins of the microcontroller, and further, may also include non-GPIO pins;

[0139] When the current configuration information of the multifunctional cable maintenance device includes the current configuration information of the receiving end, the transmitting end determines whether the line-finding interface of the receiving end is connected to multiple pins of the microcontroller of the receiving end through its corresponding overvoltage and overcurrent protection circuit and whether the positive ends of all rectifiers of the receiving end are connected in parallel to the multiple pins of the microcontroller of the receiving end and whether the negative ends of all rectifiers of the receiving end are connected in parallel to the ground end of the receiving end and whether the AC input ends of all rectifiers of the receiving end are connected to the rear stage of the self-recovery fuse. When the judgment result is yes, it is determined that the current configuration state of the multifunctional cable maintenance device meets the line-finding start condition, the multiple pins of the microcontroller of the receiving end include multiple GPIO pins of the microcontroller, and further, may also include non-GPIO pins, and all rectifiers are used to perform rectification operations on the line cores.

[0140] In an embodiment of the present invention, optionally, when it is determined that the current configuration state of the multifunctional cable maintenance device does not meet the line-finding start-up conditions, different configuration operations are performed based on different situations. For example, if the line-finding interface of the transmitting end is not connected to multiple pins of the microcontroller of the transmitting end, or the line-finding interface of the transmitting end is connected to multiple pins of the microcontroller of the transmitting end but has not passed through its corresponding overvoltage and overcurrent protection circuit and / or the analog switch and is not connected to multiple pins of the microcontroller of the transmitting end, a corresponding prompt is generated and output to relevant personnel to prompt the relevant personnel to configure the line-finding interface of the transmitting end so that the line-finding interface of the transmitting end is connected to multiple pins of the microcontroller of the transmitting end through its corresponding overvoltage and overcurrent protection circuit and / or the analog switch; if the line-finding interface of the receiving end is not connected to multiple pins of the microcontroller of the receiving end or is connected to the microcontroller of the receiving end If the multiple pins of the receiving end are connected but not passed through the corresponding overvoltage and overcurrent protection circuit, and / or the positive ends of all the rectifiers at the receiving end are not connected in parallel to the multiple pins of the microcontroller at the receiving end or the negative ends of all the rectifiers at the receiving end are not connected in parallel to the ground end of the receiving end, and / or the AC input ends of all the rectifiers at the receiving end are not connected to the rear stage of the self-resetting fuse, then a corresponding prompt is generated and output to relevant personnel to prompt the relevant personnel to configure the pairing line interface of the receiving end so that the pairing line interface of the receiving end is connected to the multiple pins of the microcontroller at the receiving end through the corresponding overvoltage and overcurrent protection circuit and the positive ends of all the rectifiers at the receiving end are connected in parallel to the multiple pins of the microcontroller at the receiving end and the negative ends of all the rectifiers at the receiving end are connected in parallel to the ground end of the receiving end and the AC input ends of all the rectifiers at the receiving end are connected to the rear stage of the self-resetting fuse.

[0141] In the embodiments of the present invention, it should be noted that the specific judgment process of "determining the current configuration information of the multifunctional cable maintenance device and judging whether the current configuration status of the multifunctional cable maintenance device meets the line search and pairing start conditions based on the current configuration information of the multifunctional cable maintenance device" can be understood as being implemented by the transmitting end, or can be understood as being implemented by the multifunctional cable maintenance device and sending the configuration judgment result to the transmitting end. It can also be understood as the configuration status of the transmitting end being implemented by the transmitting end, and the configuration status of the receiving end being implemented by the receiving end and sending the configuration judgment result to the transmitting end.

[0142] It can be seen that this optional embodiment can achieve accurate judgment of the start conditions of line finding by performing specific analysis on the current specific configuration information of the transmitting end and the current specific configuration information of the receiving end respectively, which is beneficial to improving the start accuracy of the line finding function, and further beneficial to improving the execution accuracy and reliability of the line finding function.

[0143] Embodiment 3

[0144] See also Figure 6 , Figure 6 1 is a schematic diagram of the structure of a multifunctional cable maintenance device disclosed in an embodiment of the present invention. Figure 6 The multifunctional cable maintenance device described includes a transmitter and a receiver, wherein the transmitter and the receiver communicate with each other via a cable (also called a cable), and the cable is composed of a plurality of wire cores. Among them, the types of all the wire cores can be only twisted pair types, or can be twisted pair types and shielded wire types, wherein, when two types are included, the number of wire cores corresponding to the twisted pair type is not less than the number of wire cores corresponding to the shielded wire type. Figure 6 As shown, the transmitting end may include:

[0145] The transmitting module 301 is used to transmit a line-finding signal to the receiving end through all line cores after the line-finding function is started at the transmitting end;

[0146] The transmitting module 301 is further used to transmit a handshake signal to the receiving end in the interval of transmitting the line search signal, and the handshake signal is used for the transmitting end and the receiving end to perform a handshake operation;

[0147] A detection module 302, configured to detect a first response result of the receiving end to the handshake signal;

[0148] The detection module 302 is further used to determine whether the transmitting end and the receiving end have successfully shaken hands according to the first response result;

[0149] The switching module 303 is used for the transmitting end to switch the current working mode of the transmitting end from the line-finding mode to the line-matching mode when it is determined that the handshake between the transmitting end and the receiving end is successful;

[0150] The online module 304 is used to perform online interaction with the receiving end in the online mode to obtain an online result.

[0151] It can be seen that the implementation Figure 6 After the described multifunctional cable maintenance device starts the line-finding function at the transmitting end, the transmitting end transmits a line-finding signal to the receiving end through all the wire cores, and in the intervals between transmitting the line-finding signal, transmits a handshake signal to the receiving end to request a handshake with the receiving end; when it is detected that the handshake between the transmitting end and the receiving end is successful, the transmitting end automatically switches the current working mode of the transmitting end from the line-finding mode to the line-aligning mode, and performs line-aligning interaction with the receiving end in the line-aligning mode to obtain the line-aligning result, thereby improving the efficiency and accuracy of line-finding and line-aligning, and there is no need for manual line-finding and line-aligning operations on the transmitting end and the receiving end, thereby improving the convenience of line-finding and line-aligning.

[0152] In the embodiment of the present invention, optionally, the specific manner in which the transmitting module 301 transmits a handshake signal to the receiving end in the interval between transmitting the line search signal includes:

[0153] Determine at least one first wire core from all the wire cores for transmitting a handshake signal;

[0154] In the interval of transmitting the line search signal, a handshake signal is transmitted to the receiving end through at least one first line core according to a first preset transmission mode, and the first preset transmission mode includes a simultaneous transmission mode or a one-by-one transmission mode.

[0155] In the embodiment of the present invention, optionally, at least one first core may be all selected cores or some selected cores. When some cores are selected, they may be randomly selected or deliberately selected without limitation. Further optionally, when the first preset transmission mode is a simultaneous transmission mode, as long as a response sent by the receiving end is received on one core, it indicates that the transmitter and the receiver have successfully handshaked; when the first preset transmission mode is a one-by-one transmission mode, if a response sent by the receiving end is not received on the current core, a handshake signal is transmitted through the next core, but as long as a response sent by the receiving end is received on the current core, it indicates that the transmitter and the receiver have successfully handshaked, and there is no need to transmit handshake signals through the remaining selected cores.

[0156] It can be seen that the embodiments of the present invention can also transmit handshake signals to all or part of the line cores simultaneously or one by one to the receiving end, so as to realize the successful transmission of handshake signals; and by selecting part of the line cores to transmit handshake signals, while ensuring that the handshake signal transmission is successfully received and the feedback of the receiving end is received, the handshake with the receiving end is ensured to be successful while saving the time of the handshake stage, which is conducive to further improving the line alignment efficiency; and by selecting all the line cores to transmit handshake signals, it is possible to reduce the occurrence of failure to successfully transmit handshake signals due to the good appearance of the network cable but the existence of broken line cores inside, and reduce the possibility of failure to handshake due to the existence of broken line cores, thereby improving the reliability of the successful handshake between the transmitting end and the receiving end, which is conducive to improving the reliability of switching to the line alignment function, and then helping to further improve the probability of successfully completing the line alignment.

[0157] In the embodiment of the present invention, further optionally, the alignment module 304 performs alignment interaction with the receiving end in the alignment mode, and the specific manner of obtaining the alignment result includes:

[0158] In the alignment mode, an alignment start signal is transmitted to the receiving end, and the falling edge of the alignment start signal is monitored, and the target timing corresponding to the transmitting end is determined according to the falling edge of the alignment start signal;

[0159] Based on the target timing and the interface line sequence of the pairing line interface between each line core and the transmitting end, transmitting the pairing line signal to the receiving end through all the line cores;

[0160] Detecting a second response result of the receiving end to the line signal, the second response result including a response signal made by the transmitting end to the line signal, a timing sequence of the response signal and a line sequence of the response signal;

[0161] According to the second response result, the target timing sequence, and the interface line sequence, the line alignment result between the transmitting end and the receiving end is determined.

[0162] It can be seen that in the alignment mode, the embodiment of the present invention first transmits an alignment start signal to the transmitting end so that the receiving end knows that it is ready to align the line, and uses the falling edge of the alignment start signal as a unified timing to transmit the alignment signal to the receiving end, and combines the feedback response model received from the receiving end, the timing of the response signal and the corresponding line sequence with the interface line sequence and the unified timing when it is transmitted, and performs alignment analysis on the line core between the transmitting end and the receiving end, which can achieve accuracy and reliability of the alignment analysis and obtain accurate and reliable alignment results.

[0163] In the embodiment of the present invention, further optionally, the specific manner in which the detection module 302 determines whether the handshake between the transmitting end and the receiving end is successful according to the first response result includes:

[0164] When the response right of the handshake signal belongs solely to the receiving end, the transmitting end determines whether the first response result is used to indicate that the transmitting end has received a response corresponding to the handshake signal, and when the result is yes, it is determined that the handshake between the transmitting end and the receiving end is successful;

[0165] When the response authority of the handshake signal does not belong solely to the receiving end, the transmitting end determines whether the first response result is used to indicate that the transmitting end has received a response corresponding to the handshake signal and the identifier of the response matches the identifier of the receiving end. When the judgment result is yes, it is determined that the handshake between the transmitting end and the receiving end is successful.

[0166] It can be seen that the embodiment of the present invention selects different methods to determine the success of handshake with the receiving end through the ownership authority of the handshake signal, which can improve the accuracy and reliability of determining the success of handshake between the transmitting end and the receiving end, thereby facilitating improving the accuracy of switching to the line mode for line connection.

[0167] In yet another optional embodiment, Figure 7 is a schematic diagram of the structure of another multifunctional cable maintenance device disclosed in an embodiment of the present invention, such as Figure 7 As shown, the transmitting end may also include:

[0168] A determination module 305, configured to determine current configuration information of the multifunctional cable maintenance device;

[0170] It can be seen that this optional embodiment analyzes the current configuration information of the transmitting end and / or the current configuration information of the receiving end before performing line search and pairing, and only performs subsequent line search and pairing operations after the corresponding line search and pairing starting conditions are met, which can improve the execution accuracy and reliability of the operation, thereby improving the success probability and efficiency of line search and pairing.

[0176] In yet another optional embodiment, Figure 7 As shown, the transmitting module 301 is also used to transmit a short circuit self-detection signal corresponding to each wire core to each of the wire cores in all the wire cores according to a second preset transmission mode;
