Description

Technical Field

[0001] The present application relates to the technical field of optical cable census, and in particular to a multi-channel optical cable census method, device, equipment, storage medium and product. Background Art

[0002] The optical cable survey instrument is an instrument for finding the direction of the optical cable line. It is usually composed of a signal sending and receiving module, an optical switch, an I / O interface, a signal processing module, and a communication module. Each path of the optical switch is connected to an I / O interface. When using the optical cable survey instrument, first connect the I / O interface of the optical cable survey instrument to any idle optical fiber of the optical cable, and then knock on the manhole cover, electric pole and other external auxiliary facilities on the route where the optical cable may pass to generate a knocking vibration signal. The optical cable survey instrument determines the route of the optical cable by detecting the knocking vibration signal in the optical cable.

[0003] The optical cable survey instrument can connect multiple optical cables at the same time, and by polling the optical switch in the optical cable survey instrument, multiple optical cables can be tested at the same time. When an external force (such as knocking) acts on the optical cable, the time it takes for the knocking vibration signal to propagate in the optical cable and gradually weaken to an undetectable state (generally half of the maximum value of the knocking vibration signal) is called the attenuation time. Since the attenuation time of the knocking vibration signal generated by the knocking in the optical cable is relatively short, when the number of channels of the optical switch is relatively large, it is impossible to complete the polling of all channels within the attenuation time generated by one knocking. Therefore, frequent knocking for a long time is required to increase the probability of each channel being polled. However, the current knocking is relatively random and blind, which makes it easy for optical cables to be missed. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a multi-channel optical cable census method, device, equipment, storage medium and product to solve the problem in the prior art that the tapping is relatively random and blind, which leads to easy leakage of optical cables.

[0014] As another improvement of the above solution, setting the tapping interval time according to the polling time includes:

[0015] According to the polling time, the tapping interval is set to ts, wherein ts is the polling time of each channel.

[0016] As an improvement of the above solution, the tapping interval is 500ms to 1000ms.

[0017] As an improvement of the above solution, the polling time is less than or equal to the time it takes for the knocking vibration signal to decay from a maximum value to a preset value in the optical cable.

[0018] The embodiment of the present application also provides a multi-channel optical cable census device, comprising:

[0023] An embodiment of the present application further provides a computer program product, including a computer program, wherein when the computer program is executed by a processor, the multi-channel optical cable census method described in any one of the above items is implemented.

[0024] Compared with the prior art, the beneficial effects of a multi-channel optical cable census method, device, equipment, storage medium and product provided by the embodiments of the present application are: by setting the tapping interval time according to the polling time of each channel of the optical cable census instrument, the tapping interval time and the polling time are set to be positively correlated, so that the tapping interval time and the polling time have a certain synchronization relationship, and then the optical cable census instrument can always switch to different optical cables during two adjacent tappings, so that there is no need to perform long-term and frequent tapping tests. The optical cable census instrument can poll all optical cables, which can avoid the phenomenon of optical cable missed detection, and make the probability of each channel being polled balanced, thereby improving the efficiency and accuracy of the optical cable census.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] See also Figure 1 , Figure 1 It is a structural diagram of an optical cable survey instrument. The part connected by solid lines in the figure is the optical path part, and the part connected by dotted lines is the circuit part. The optical cable survey instrument includes a signal sending and receiving module, an optical switch, an I / O interface, a signal processing module and a communication module. Among them, the optical switch is a 1×N optical switch, N is the number of channels, which can be 16, 20, 32, 48 or 64. Each channel of the optical switch is connected to an I / O interface. The I / O interface is an optical fiber active connection interface, which can be connected to an optical fiber in the optical cable through a jumper through an ODF (Optical Distribution Frame). The communication module can communicate with the outside world via wired or wireless means.

[0035] See also Figure 2 , Figure 2 It is a schematic diagram of the principle of optical cable survey. When conducting an optical cable survey, first connect the optical cable survey instrument (instrument) to any idle optical fiber in the optical cable to be surveyed through a jumper; then, use a hammer or other tools to knock on facilities such as manhole covers and electric poles on the route where the optical cable may pass. The optical cable survey instrument uses the principle of φ-OTDR to detect the knocking vibration signal in the optical cable. When the vibration position and intensity information detected by the optical cable survey instrument match the actual knocking point position and knocking intensity, it means that the optical cable passes through the hand hole or electric pole at the knocking point; if it does not match, it means that the optical cable does not pass through the hand hole or electric pole at the knocking point. Furthermore, by knocking on external ancillary facilities such as manhole covers and electric poles on the route where the optical cable may pass, the route of the optical cable can be determined and an optical cable survey can be achieved.

[0036] See also Figure 3 , Figure 3 This is a schematic diagram of a multi-channel simultaneous test of an optical cable survey instrument. The optical cable survey instrument can connect multiple optical cables at the same time, and select any idle optical fiber from each optical cable and connect it to the I / O interface of the optical cable survey instrument through a jumper. By polling the optical switch in the optical cable survey instrument, multiple optical cables can be tested at the same time. When multiple optical cables pass through the same hand hole or pole, the corresponding hand hole cover or pole can be knocked, and the optical cable survey instrument can determine which optical cables pass through the hand hole or pole, thereby realizing a multi-channel optical cable survey.

[0037] The polling time of each channel of the optical cable survey instrument is the polling time of each channel of the optical switch of the optical cable survey instrument. Generally speaking, for the same optical cable survey instrument, the polling time of each channel is the same. One polling (switching from one channel to the next) time includes the switching time of the optical switch and the connection time of the channel, that is, the polling time of each channel = the switching time of the optical switch + the connection time of the channel.

[0038] See also Figure 4 , Figure 4 It is a diagram showing the relationship between attenuation time and polling time when the optical cable survey instrument is testing. Generally, if the attenuation time td is completely within 1 polling time ts (counted as 1 time slot), the optical cable survey instrument will poll 1 channel when it is struck, such as Figure 4 As shown in td1, within the attenuation time td1, the optical cable survey instrument can poll the channel corresponding to the time slot ts1; if the attenuation time td spans 2 or 3 time slots ts, the optical cable survey instrument will poll 2 or 3 channels when tapping, as shown in Figure 4 As shown in td2 and td3, within the decay time td2, the optical cable survey instrument can poll the two channels corresponding to time slots ts3 and ts4, and within the decay time td3, the optical cable survey instrument can poll the three channels corresponding to time slots ts6, ts7 and ts8. However, the decay time of the knock vibration signal in the optical cable is relatively short. When there are many channels to be polled, one decay time td cannot span more time slots ts, that is, the optical switch often cannot complete the polling of all channels within the decay time generated by one knock.

[0039] Therefore, the probability of each channel being polled is increased by continuously knocking on the manhole cover or pole. However, this is done randomly and blindly, which often results in some channels being polled after many knocks, or even some channels never being polled. For example, the number of channels N of the optical cable survey instrument is 16, the polling time ts of each channel is 100ms, and the polling cycle (i.e., the total polling time of all channels of the optical cable survey instrument) T = ts × N = 100ms × 16 = 1600ms. If the knocking interval is 800ms, then the channels polled by the optical cable survey instrument are the same every two knocks, resulting in missed detection of optical cables connected by multiple channels.

[0040] Therefore, an embodiment of the present application provides a multi-channel optical cable census method to solve the problem that an optical cable census instrument needs to perform long-term and frequent tapping when conducting a multi-channel census, which is relatively random and blind, and the probability of different channels being polled during tapping is uneven, which easily leads to missed detections.

[0041] See also Figure 5 , Figure 51 is a flow chart of a multi-channel optical cable census method provided in an embodiment of the present application. The multi-channel optical cable census method comprises:

[0042] S1: Get the polling time of each channel of the optical cable survey instrument;

[0043] S2: according to the polling time, a knocking interval is set, so that when the knocking test is performed according to the knocking interval, the optical cable survey instrument performs an optical cable survey according to the polling time to obtain an optical cable survey result;

[0044] The tapping interval time is positively correlated with the polling time.

[0045] Specifically, the communication module of the optical cable survey instrument can be connected to the cloud management platform (i.e., a server deployed in the cloud) by wire or wireless means, and survey personnel can use the terminal to communicate with the optical cable survey instrument through the cloud management platform. When survey personnel conduct an optical cable survey on the optical cable route, they open the corresponding optical cable survey application on the terminal and send a start test instruction to the optical cable survey instrument through the application; when the optical cable survey instrument receives the start test instruction, it prepares for the optical cable survey test.

[0046] When the optical cable survey instrument is ready, the application obtains the polling time of each channel of the optical cable survey instrument, and sets the knocking interval time (i.e. the interval time between two adjacent knocks) according to the polling time; wherein the knocking interval time is positively correlated with the polling time.

[0047] The polling time can be obtained by querying the configuration file of the optical cable survey instrument, or it can be set in advance by the user. For the latter, the survey personnel can select the required polling time through the optical cable survey application, and then the application sends the selected polling time to the optical cable survey instrument, so that the optical cable survey instrument controls the optical switch to poll according to the selected polling time. The polling time is preferably 50ms to 100ms, so as to avoid misjudgment caused by too short connection time of each channel, and improve the accuracy of optical cable survey.

[0048] The application prompts the knocking interval by sound and / or text and / or numbers, or sends the knocking interval to a knocker, so that the knocker knocks the external auxiliary facilities of the optical cable according to the knocking interval.

[0049] For example, like an electronic metronome, sound and / or text and / or numbers are used to prompt the knocking interval, so that census workers can use tools such as hammers to knock on external ancillary facilities such as manhole covers and electric poles according to the knocking interval prompted by the application.

[0050] It is understandable that when the number of channels of the optical cable survey instrument is large (such as 48 channels and above), it often takes a long time of uninterrupted tapping to conduct a survey at one location, which is time-consuming and prone to errors. In this case, a knocker can be used for tapping. The knocker is connected to the terminal via Bluetooth. When the optical cable survey application starts running, the knocking interval is transmitted to the knocker, and the knocker knocks on external ancillary facilities such as manhole covers and electric poles according to the knocking interval to complete the optical cable survey. In addition, the knocking intensity can also be transmitted to the knocker, and the knocker knocks according to the knocking intensity.

[0051] At the same time, the optical switch in the optical cable survey instrument polls according to the polling time to complete the optical cable survey and obtain the optical cable survey results. The optical cable survey results can also be sent to the terminal in real time for the convenience of survey personnel to view.

[0052] In the embodiment of the present application, since the polling time is proportional to the knocking interval time, the knocking interval time maintains a certain synchronization relationship with the polling time. When the census personnel conduct an optical cable census in a hand hole or pole, they only need to knock several times in succession to quickly determine how many optical cables pass through the hand hole or pole at the same time, without the need for long and frequent knocking.

[0053] As one of the optional embodiments, setting the tapping interval time according to the polling time includes:

[0054] According to the polling time, the tapping interval is set to ts, wherein ts is the polling time of each channel.

[0055] For example, using a 16-channel optical cable survey instrument to survey 16 optical cables at the same time, the tapping interval is set to keep the tapping interval consistent with the polling time of each optical switch channel. For example, when the polling time of each channel is set to 1s, the tapping interval is also set to 1s. When conducting an optical cable survey, the surveyor taps 16 times at a beat of 1 per second to complete the polling of 16 channels.

[0056] The embodiment of the present application can balance the probability of different channels being polled during tapping, and can poll all optical cables without long tapping, thereby avoiding the phenomenon of optical cable leakage.

[0057] As another optional embodiment, setting the tapping interval time according to the polling time includes:

[0058] Obtaining the number of channels of the optical cable survey instrument;

[0059] The tapping interval is set according to the number of channels and the polling time; wherein the tapping interval is positively correlated with the number of channels.

[0060] Further, the step of setting the tapping interval according to the number of channels and the polling time includes:

[0061] According to the number of channels and the polling time, the tapping interval is set to or Where ts is the polling time of each channel, N is the number of channels, and m is a positive number.

[0062] For example, using a 16-channel optical cable survey instrument to survey 16 optical cables at the same time, the tapping interval is set to or Where ts is the polling time and m is a positive number.

[0063] The polling time ts is set to 100ms. When the value of m is 1, the tapping interval is 1500ms or 1700ms. At this time, the optical cable survey instrument can poll different channels each time it taps. For example, when the tapping interval is set to 1500ms, if the optical cable survey instrument polls the 5th optical cable (corresponding to channel 5) during the first tap, the optical cable survey instrument polls the 4th optical cable during the second tap, and the optical cable survey instrument polls the 3rd optical cable during the third tap, and so on. As long as the tapping interval is kept at the same time, the optical cable survey instrument can poll the 16 channels in turn.

[0064] As an optional embodiment, the tapping interval is 500ms to 1000ms.

[0065] Preferably, when taking the value of m, the tapping interval is: or It is between 500ms and 1000ms to suit people's operating habits.

[0066] For example, the polling time ts is set to 100ms. When m is set to 1 so that the tapping interval is greater than 1000ms, m can be set to 2, and the tapping interval is or That is, 750ms or 850ms. When the tapping interval is 750ms, the relationship between the tapping sequence, polling cycle and the channel is as follows: Figure 6As shown, the numbers in the gray cells represent the sequence number of the knocks. For example, the numbers in the cells corresponding to channel 5 in the polling cycle T1 represent the first knock. During the decay time of the first knock, the optical cable survey instrument polls channel 5. In the gray cells, when the numbers with the same sequence number span two adjacent cells, it means that the optical cable survey instrument will poll two channels within one knock time. For example, during the second knock, the optical cable survey instrument can poll channels 12 and 13. Since the polling time usually does not exceed the decay time, that is, each knock usually has 1 to 3 (at least 1) optical cables that can detect the vibration signal, then for the two knocks in one polling cycle, at least 3 optical cables can sense the vibration signal. Therefore, within N-1 polling cycles (equivalent to 24s), all 16 optical cables sense the vibration signals of at least 3 knocks, which greatly reduces the probability of misjudgment caused by knock errors or other noise interference.

[0067] The embodiment of the present application can make the probability of different channels being polled equal when tapping, and all optical cables can be polled without long tapping. In addition, not only the probability of misjudgment caused by tapping errors or other noise interference is greatly reduced, but also the number of tappings does not need to be counted again from the tapping error, which is suitable for the situation where there are many optical cables connected to the optical cable survey instrument.

[0068] As an optional embodiment, the polling time is less than or equal to the time it takes for the knocking vibration signal to decay from a maximum value to a preset value in the optical cable.

[0069] Wherein, the preset value is set to half of the maximum value of the knocking vibration signal.

[0070] Specifically, the time it takes for the knock vibration signal to decay from the maximum value to half in the optical cable, i.e., the decay time, is usually 50 ms to 200 ms.

[0071] In the prior art, the optical cable survey requires the arrangement of personnel to operate the optical cable survey instrument and the optical cable route survey (at least two people in a group), and the survey personnel need to climb poles or go down wells, which is not only inefficient, but also has safety risks. On average, a group can only survey about 10 kilometers of optical cables per day. However, by using the method of the embodiment of the present application to conduct a survey, only one person is needed to complete the operation, and the operation is simple. Normally, about 200 kilometers of optical cables can be surveyed every day, which greatly improves the survey efficiency. While helping to improve the accuracy of resources, it also provides a solid foundation for optical cable resource planning and network optimization layout.

[0072] Compared with the prior art, the embodiment of the present application does not require long-term tapping of external auxiliary facilities such as manhole covers and electric poles when conducting multi-optical cable testing, and is not prone to missed detection. For example, for a 16-channel optical cable survey instrument, when the polling time is set to 100ms or 50ms, it only takes 24 seconds or 12 seconds to poll all channels. If the optical cables connected to the 16 channels all pass through the same tapping point, then each optical cable will sense at least 3 tapping vibrations, which reduces the probability of missed detection and improves the efficiency of optical cable surveys.

[0073] Correspondingly, the present application also provides a multi-channel optical cable census device, which can implement all processes of the multi-channel optical cable census method in the above embodiment.

[0074] See also Figure 7 , Figure 7 1 is a schematic diagram of the structure of a multi-channel optical cable census device provided in an embodiment of the present application. The multi-channel optical cable census device comprises:

[0075] The polling time acquisition module 701 is used to acquire the polling time of each channel of the optical cable survey instrument;

[0076] The tapping interval setting module 702 is used to set the tapping interval according to the polling time, so that when the tapping test is performed according to the tapping interval, the optical cable survey instrument performs an optical cable survey according to the polling time to obtain an optical cable survey result; wherein the tapping interval is positively correlated with the polling time.

[0077] Preferably, the tapping interval setting module 702 is further used for:

[0078] Obtaining the number of channels of the optical cable survey instrument;

[0079] The tapping interval is set according to the number of channels and the polling time; wherein the tapping interval is positively correlated with the number of channels.

[0080] Preferably, the tapping interval setting module 702 is further used for:

[0081] According to the number of channels and the polling time, the tapping interval is set to or Where ts is the polling time of each channel, N is the number of channels, and m is a positive number.

[0082] Preferably, the tapping interval setting module 702 is further used for:

[0083] According to the polling time, the tapping interval is set to ts, wherein ts is the polling time of each channel.

[0084] Preferably, the tapping interval is 500ms to 1000ms.

[0085] Preferably, the polling time is less than or equal to the time it takes for the knocking vibration signal to decay from a maximum value to a preset value in the optical cable.
