The following are detailed descriptions respectively.

[0055] Embodiment 1

[0056] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a line-finding receiving device integrated with a local line-matching function disclosed in an embodiment of the utility model. Figure 1 As shown, the line search receiving device 10 at least includes a main control circuit 101, a line search signal receiving circuit 102, a line search result output circuit 103 and a power supply circuit 104. In addition, the line search receiving device 10 may also include a local line matching circuit 105. The local line matching circuit 105 may include:

[0057] A first cable access port 1051 and a second cable access port 1052;

[0058] A pulse control circuit 1053, wherein the signal input terminal of the pulse control circuit 1053 is used to electrically connect to the line control terminal of the main control circuit 101, and the voltage terminal of the pulse control circuit 1053 is electrically connected to the power output terminal of the power supply circuit 104;

[0059] A first indication circuit 1054, wherein a first end of the first indication circuit 1054 is electrically connected to a signal output end of the pulse control circuit 1053, and a second end of the first indication circuit 1054 is electrically connected to a first end of the first cable access port 1051;

[0060] The second indication circuit 1055 , wherein a signal input end of the second indication circuit 1055 is electrically connected to a first end of the second cable access port 1052 .

[0061] Among them, in the local alignment mode of the line-finding receiving device 10, the second end of the first cable access port 1051 is used for access to one end of the cable to be aligned, and the second end of the second cable access port 1052 is used for access to the other end of the cable to be aligned, and the first indication circuit 1054 and the second indication circuit 1055 are used to respectively output the alignment results of the local alignment circuit 105 for the cable to be aligned.

[0062] In the embodiment of the utility model, a start button of the local line mode is provided on the line-finding receiving device 10, and the start button is used for the cable maintenance personnel to trigger and start the local line mode of the line-finding receiving device 10, and the start button can be a physical button on the line-finding receiving device 10, or a touch icon displayed on the display screen of the line-finding receiving device 10. Optionally, when the start button is a physical button, it can be a physical button already on the line-finding receiving device 10, or a physical button newly added to the line-finding receiving device 10. Further, when the physical button is a physical button already on the line-finding receiving device 10, relevant personnel (such as cable maintenance personnel or the manufacturer of the line-finding receiving device 10, etc.) can pre-set the corresponding relationship between the pressing parameters such as the number of presses, the pressing duration, and the pressing time interval of the existing physical button and the control mode, and the cable maintenance personnel can trigger and start the local line mode through the corresponding pressing parameters. For example, if the cable maintenance personnel presses the physical button once, the control mode started is the line-finding mode; if the cable maintenance personnel presses the physical button twice within 3 seconds, the control mode started is the local line-matching mode.

[0063] Specifically, when it is necessary to use the line-finding receiving device 10 to achieve line alignment, the cable maintenance personnel can insert one end of the cable to be aligned into the first cable access port 1051, and insert the other end of the cable to be aligned into the second cable access port 1052, and after the local line alignment mode is started, under the power supply of the power supply circuit 104 and the clock signal output by the main control circuit 101, the pulse control circuit 1053 cyclically outputs the pulse square wave signal, and then controls the first indication circuit 1054 and the second indication circuit 1055 to output the alignment result of the cable inner core according to the received pulse square wave signal and the actual on-off condition of the cable inner core. Among them, the frequency of the pulse square wave signal output by the pulse control circuit 1053 can be adjusted by the main control circuit 101, and the first indication circuit 1054 and the second indication circuit 1055 respectively include an indication sub-circuit corresponding to each cable inner core, and the cable maintenance personnel can determine the alignment result of the corresponding cable inner core according to the on-off condition of the indication sub-circuit.

[0064] Optionally, the pulse control circuit 1053 is also provided with a reset end, and its reset end is electrically connected to the alignment reset control end of the main control circuit 101. By setting the corresponding reset end, it is possible to ensure that the first indication circuit 1054 starts to indicate the alignment result of the cable core from a fixed indication sub-circuit each time the local alignment mode of the line-finding receiving device 10 is switched.

[0065] In other optional embodiments, the above-mentioned line-finding receiving device 10 can also realize line alignment together with a device having a line alignment implementation circuit, that is, the above-mentioned line-finding receiving device 10 can also have the function of remote line alignment. Among them, the above-mentioned line alignment implementation circuit at least includes the above-mentioned main control circuit 101, the above-mentioned first cable access port 1051, the above-mentioned pulse control circuit 1053 and the above-mentioned first indication circuit 1054. When line alignment is required, one end of the cable to be aligned is connected to the second cable access port 1052 of the above-mentioned line-finding receiving device 10, and the other end of the cable to be aligned is connected to the first cable access port 1051 of the above-mentioned line alignment implementation circuit. In this way, both local line alignment and remote line alignment can be realized through the line-finding receiving device 10, which further expands the cable maintenance function of the line-finding receiving device 10 and is conducive to further improving the cable maintenance experience of the cable maintenance personnel using the line-finding receiving device 10.

[0066] It can be seen that the embodiment of the utility model can integrate the local wiring function on the existing line-finding receiving device. When the line-finding receiving device needs to be used for wiring, it is only necessary to connect the two ends of the cable to be aligned to the two local wiring ports on the line-finding receiving device respectively, and combine the pulse control circuit and the two indication circuits to realize the intuitive output of the wiring results, which not only enriches the cable maintenance function of the line-finding receiving device, but also can improve the convenience and efficiency of wiring.

[0067] In an optional embodiment, if Figure 2 As shown, the line search receiving device 10 may further include a POE power supply line sequence identification circuit 106, wherein:

[0068] A first end of the POE (Power Over Ethernet) power supply line sequence identification circuit 106 is electrically connected to a first end of the second cable access port 1052 and a signal input end of the second indication circuit 1055 respectively;

[0069] The second terminal and the third terminal of the POE power supply line sequence identification circuit 106 are respectively used as reference ground terminals of the POE power supply line sequence identification circuit 106 .

[0070] In this optional embodiment, when one end of a cable is connected to a POE switch and the other end of the cable is connected to the first end of the second cable access port 1052, the POE switch detects that the load is successfully connected. At this time, the POE switch is used to power the POE power supply line sequence identification circuit 106; the POE power supply line sequence identification circuit 106 is used to convert the power supply voltage signal output by the POE switch into a DC power supply signal and provide it to the second indication circuit 1055. The second indication circuit 1055 is used to output a POE power supply line sequence identification signal according to the DC power supply signal.

[0071] It can be seen from this optional embodiment that the second cable access port 1052 can not only realize local wiring in the local wiring mode, but also realize connection with the POE switch and identify the power supply line sequence of the POE switch. In addition, the second indication circuit 1055 can not only realize the indication of the wiring result in the local wiring mode, but also realize the indication of the power supply line sequence identification result in the POE power supply line sequence identification mode. In this way, different cable maintenance functions in different cable maintenance modes are realized by multiplexing the corresponding circuit structure. On the basis of expanding the cable maintenance function of the line-finding receiving device 10, the complexity of the circuit structure in the line-finding receiving device 10 is reduced, which is conducive to saving space for the design of the line-finding receiving device 10 and can also save time for cable maintenance.

[0072] It should be noted that: in other optional embodiments, the line-finding receiving device 10 may include the above-mentioned second cable access port 1052, second indication circuit 1055 and POE power supply line sequence identification circuit 106 in addition to the main control circuit 101, the line-finding signal receiving circuit 102, the line-finding result output circuit 103 and the power supply circuit 104, thus forming a line-finding receiving device 10 with integrated POE power supply line sequence detection function. That is: the POE power supply line sequence detection function integrated in the line-finding receiving device 10 can exist independently of the local line matching function and the remote line matching function of the line-finding receiving device 10.

[0073] In another optional embodiment, Figure 3 As shown, the line-finding receiving device 10 may further include an optical fiber fault detection circuit 107, and the optical fiber fault detection circuit 107 may include:

[0074] Detection signal output circuit 1071;

[0075] The optical fiber detection control circuit 1072 has a signal output terminal electrically connected to a signal input terminal of the detection signal output circuit 1071, an enable terminal of the optical fiber detection control circuit 1072 is used to electrically connect to the optical fiber detection control terminal of the main control circuit 101, a ground terminal of the optical fiber detection control circuit 1072 is used to ground, and a power terminal of the optical fiber detection control circuit 1072 is used to electrically connect to a target power supply, and the target power supply is used to power the optical fiber fault detection circuit 107.

[0076] In this optional embodiment, the optical fiber detection control circuit 1072 is used to receive the optical fiber detection enable signal (such as a high level signal) output by the main control circuit 101, and output a control signal (such as a voltage signal, a current signal, etc.) to the detection signal output circuit 1071 according to the optical fiber detection enable signal; the detection signal output circuit 1071 is used to output an optical fiber fault detection signal to the optical fiber to be detected for fault according to the control signal. Optionally, the optical fiber fault detection signal can be an optical signal, and further, the optical signal can be a red light signal.

[0077] It can be seen that this optional embodiment can also integrate the optical fiber fault detection circuit 107 on the line-finding receiving device 10, so that optical fiber fault detection and optical fiber fault point positioning (such as optical fiber breakpoints, optical fiber bending points, leakage points) can be achieved without carrying special optical fiber fault detection equipment, which is beneficial to improving the efficiency and convenience of optical fiber fault detection, and can also further improve the user experience of the line-finding receiving device 10.

[0078] In this optional embodiment, further optional, such as Figure 3 As shown, the optical fiber fault detection circuit 107 may further include a feedback circuit 1073, wherein:

[0079] One end of the feedback circuit 1073 is electrically connected to the feedback end of the detection signal output circuit 1071 and the detection end of the optical fiber detection control circuit 1072 , and the other end of the feedback circuit 1073 is grounded.

[0080] The feedback circuit 1073 is used to collect the working parameters corresponding to the detection signal output circuit 1071 and feed back the working parameters to the optical fiber detection control circuit 1072, wherein the working parameters at least include the working voltage and / or the working current. Further optionally, the feedback circuit 1073 may specifically include a feedback resistor.

[0081] It can be seen that in this optional embodiment, after receiving the working parameters fed back by the feedback circuit 1073, the optical fiber detection control circuit 1072 determines whether the detection signal output circuit 1071 is working in a stable voltage and constant current state. Further, if it is determined that the detection signal output circuit 1071 is not working in a stable voltage and constant current state, the control signal output to the detection signal output circuit 1071 can be further adjusted to achieve stable voltage and constant current control of the detection signal output circuit 1071, thereby improving the output stability of the optical fiber fault detection signal. In addition, the feedback or collection of working parameters through the detection resistor is also conducive to reducing circuit costs.

[0082] It should be noted that for Figure 3 For one optional circuit structure of the optical fiber fault detection circuit 107, the detailed circuit structure, the connection relationship between the detailed circuit structures, the electronic devices included in the detailed circuit structure and the connection relationship between the electronic devices can be referred to. Figure 6 , Figure 6 The utility model discloses a structure diagram of an optical fiber fault detection circuit.

[0083] In yet another optional embodiment, further optional, such as Figure 3 As shown, the line search receiving device 10 may further include a crimping detection circuit 108, and the crimping detection circuit 108 may include:

[0084] A signal generating circuit 1081, wherein the control end of the signal generating circuit 1081 is electrically connected to the crimping control signal output end of the main control circuit 101, and the crimping test channel of the signal generating circuit 1081 is electrically connected to the cable access port, and the cable access port is used for cable access, wherein the cable access port may be the first cable access port 1051, or the second cable access port 1052, or other cable access ports different from the first cable access port 1051 and the second cable access port 1052;

[0085] The second signal conversion circuit 1082 has an input end electrically connected to a signal output end of the signal generating circuit 1081 , and an output end of the second signal conversion circuit 1082 electrically connected to a crimping detection signal input end of the main control circuit 101 .

[0086] The implementation principle of crimping detection circuit 108 for crimping detection is as follows:

[0087] When crimping detection is required, the signal generating circuit 1081 is used to determine the target channel to be tested according to the crimping detection control signal output by the main control circuit 101, collect the capacitance value corresponding to the target channel to be tested and output it to the second signal conversion circuit 1082; the second signal conversion circuit 1082 is used to perform signal conversion operations on the capacitance value to obtain a pulse frequency signal matching the capacitance value, and output the pulse frequency signal to the main control circuit 101, and the pulse frequency signal is used for the main control circuit 101 to determine the crimping condition of the crystal head of the cable connected to the corresponding cable access port.

[0088] Furthermore, this optional embodiment can also indicate the crimping detection result of the crimping detection circuit 108 through a corresponding indicating circuit.

[0089] It can be seen that this optional embodiment can also integrate a crimping detection function on the line-finding receiving device 10 described in the aforementioned embodiment, so that while performing basic maintenance operations on the cable (such as line-finding operations, line alignment operations, and POE power supply line sequence detection operations), it can also implement crimping detection of the cable, which is beneficial to improving the convenience and efficiency of crimping detection of the cable, thereby improving the convenience and efficiency of cable maintenance, and can also improve the user experience of the line-finding receiving device 10. In addition, crimping detection can be implemented by connecting the cable to the corresponding interface without switching or selecting functions, and it does not affect other functions of the line-finding receiving device 10, further improving the convenience and efficiency of crimping detection using a line-finding receiving device integrated with a crimping detection circuit 103.

[0090] It should be noted that for Figure 3 For one of the optional circuit structures of the crimping detection circuit 108, the detailed circuit structures, the connection relationship between the detailed circuit structures, the electronic devices included in the detailed circuit structures, and the connection relationship between the electronic devices can be referred to.

Figure 4As shown, the first cable access port 1051 is J2, the second cable access port 1052 is J4, the first indication circuit 1054 includes indicator lights D12 to D20, the second indication circuit includes indicator lights LED1 to LED10, the pulse control circuit 1053 includes U6, and pin 14 of U6 is used as the signal input end of the pulse control circuit 1053, pin 15 of U6 is used as the reset end, and pins 1-11 of U are used as the signal output end of the pulse control circuit 1053. Further, the signal input end of the pulse control circuit 1053 can be electrically connected to the line control end CPU_CLK of the main control circuit 101 through a circuit composed of a resistor R22 and a transistor Q1, and the reset end of the pulse control circuit 1053 can be electrically connected to the line reset control end CPU_RST of the main control circuit 101 through a circuit composed of a resistor R23 and a transistor Q2.
