[0002] There are more and more optical fibers laid for communication within and between cities. Due to the long construction period and non-standard construction, the optical fibers in many communication wells are messy and unrecognizable. When the optical fiber is abnormal and cannot be used, it is necessary to find the specific location of the abnormal fiber for repair. In the actual inspection of the optical fiber line, the faulty optical fiber is usually mixed with the optical fibers of other lines.

The various types of occurrences of the phrase in the specification do not necessarily all refer to the same embodiment, nor are they independent or alternative embodiments that are mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] See also Figure 1 , which shows a structural block diagram of a survey instrument with integrated WiFi communication and wireless intercom functions provided by an embodiment of the present invention, including the following units:

[0042] The optical fiber attribute information and light source type label acquisition unit 101 acquires the type label of each light source, and acquires the optical fiber attribute information of multiple nodes through the light sources with each type label.

[0043] It should be noted that there are many factors that cause fiber optic attribute information failures, including changes in the distance between the optical fiber and the light source, light source failure, and intercom fiber optic attribute information failure. In order to achieve accurate intercom fiber optic attribute information failure monitoring, the communication of the other two factors needs to be excluded.

[0044] In order to realize the survey instrument with integrated WiFi communication and wireless intercom functions proposed in this embodiment, data is first acquired, and the acquired data includes: type labels of light sources and optical fiber attribute information of multiple nodes.

[0045] Arrange light sources: select several types of light sources to obtain optical fiber property information in the optical fiber communication center, select a point on the ground of the communication center as the origin, and construct a ground coordinate system through the origin to the north as the u-axis direction, to the east as the v-axis direction, and to the top as the q-axis direction. Obtain the coordinate point of each light source in the ground coordinate system, and identify the Euclidean distance between the light sources based on the coordinate points of the light sources.

[0046] The process of obtaining the type label of the light source is as follows: all light sources are formed into a light source list, the light source in the upper left corner is taken as the first light source, the first superposition distance sum is set to 0, the type label of the first light source is set to the first superposition distance sum, the first light source is removed from the light source list to identify the first remaining light source list, and then the light source closest to the first light source is obtained in the first remaining light source list as the second light source, the cumulative sum of the Euclidean distance between the first light source and the second light source and the first superposition distance sum is recorded as the second superposition distance sum, the type label of the second light source is set to the second superposition distance sum, the second light source is removed from the first remaining light source list to identify the second remaining light source list, and then the light source closest to the second light source is obtained in the second remaining light source list as the third light source, the Euclidean distance between the third light source and the second light source is added to the second superposition distance sum to identify the third superposition distance sum, the type label of the third light source is set to the third superposition distance sum, and so on, to set a type label for each light source.

[0047] The specific process of obtaining the optical fiber attribute information is: obtain the optical fiber attribute information of the light source of each type of label once every 30 seconds, and obtain the optical fiber attribute information N times. This embodiment is described by taking N as 10000 as an example. Other embodiments may take other values, and this embodiment does not make specific restrictions.

[0048] So far, the type label of each light source and the multiple optical fiber property information acquired by the light source with each type label are identified by the above method.

[0049] The communication fault status acquisition unit 102 for each fault location performs fault detection on the optical fiber attribute information acquired by the light source of each type of tag to identify the fault location, analyzes the timing correlation and spatial correlation of each fault location to identify the wireless transmission status of each fault location, and identifies the communication fault status of each fault location in combination with the change characteristics of the optical fiber attribute information of each fault location.

[0050] It should be noted that optical fiber can generally only grow healthily within a certain range of intercom optical fiber attribute information. Therefore, a preset optical fiber attribute information range is set based on the intercom optical fiber attribute information required for the healthy growth of the optical fiber, and a fault judgment is performed on the acquired optical fiber attribute information based on the preset optical fiber attribute information range.

[0051] It should be further noted that in real life, during the movement of the optical fiber, it will not always move closely along each light source, but will occasionally pass near a small part of the light sources. Therefore, after the optical fiber moves, the light sources within a certain spatial range will obtain the attribute information of the faulty optical fiber. Since the optical fiber passes near each light source in sequence, when the optical fiber reaches each light source, this light source will obtain the attribute information of the faulty optical fiber. Therefore, the movement of the optical fiber will cause the light sources within a certain range to obtain the attribute information of the faulty optical fiber in sequence, and based on this feature, the wireless transmission performance of each fault location is calculated.

[0052] Specifically, a three-dimensional Cartesian coordinate system is set up, where the x-axis represents the coordinate axis, the y-axis represents the type label axis, and the z-axis represents the optical fiber attribute information axis. The coordinate points of the optical fiber attribute information of each node obtained by the light sources of each type label in the coordinate system are obtained; it is judged whether the optical fiber attribute information of each node obtained by the light sources of each type label belongs to the preset optical fiber attribute information range W = [e1, e2]. The coordinate points corresponding to the optical fiber attribute information that does not belong to the preset optical fiber attribute information range are used as the fault locations, where e2 and e1 respectively represent the upper limit value and the lower limit value of the preset optical fiber attribute information range. In this embodiment, e1 and e2 are taken as 15 and 25 respectively for description, and other values can be taken in other embodiments, and this embodiment does not make specific limitations.

[0053] Further, the coordinate of the i-th fault location is (x i , y i , z i ). The range (x - x i ) 2 +(y - y i ) 2 < R is used as the neighborhood range of the i-th fault location, and the fault locations within the neighborhood range are used as the candidate fault locations of the i-th fault location. R represents the preset radius threshold. In this embodiment, R is taken as 5 for description, and other values can be taken in other embodiments, and this embodiment does not make specific limitations; similarly, the candidate fault locations of each fault location are identified, and the calculation method for identifying the wireless transmission performance of each fault location based on the candidate fault locations of each fault location is as follows:

[0054]

[0055] Among them, represents the coordinate distance between each fault location and the k-th candidate fault location. The larger this value is, the longer the coordinate interval between this fault location and this candidate fault location is. Δt kIndicates the type label distance between each fault location and the kth candidate fault location. The larger the value, the farther the light source corresponding to the fault location is from the light source corresponding to the candidate fault location. α and β respectively represent the preset coordinate priority value and the preset type priority value. This embodiment is described by taking α as 0.32 and β as 0.68 as an example. Other embodiments may take other values. This embodiment is not specifically limited. K represents the number of candidate fault locations for each fault location. Max_Min() represents the normalization processing by the maximum and minimum value normalization method. It reflects the distance between the light source corresponding to each fault position and the light source corresponding to the candidate fault position. The larger the value, the more the light sources within a certain spatial range obtain the fault fiber attribute information in sequence. Therefore, the fault fiber attribute information is caused by the optical fiber passing through the vicinity of each light source in sequence. It reflects the coordinate interval between each fault location and the candidate fault location. The larger the value, the larger the coordinate interval of the fault fiber attribute information within a certain coordinate range. Therefore, the fault fiber attribute information is because the fiber moves from one light source to the next light source. The distance between the fiber and the two light sources is far, and the two light sources cannot obtain the fault fiber attribute information during this period. Therefore, the coordinate interval of the fault fiber attribute information is large. TL represents the wireless transmission performance of each fault location.

[0056] It should be noted that the optical fiber attribute information obtained from the light source failure will remain unchanged, and the communication fault status of each fault location is calculated based on this feature.

[0057] Further, each fault location in the coordinate system is mapped to the x-axis to identify the signal tower at each fault location, the continuously distributed signal towers form a signal tower list, the list of all signal towers is obtained, each signal tower in the signal tower list is replaced by the fault location corresponding to the signal tower to identify the fault location list, in each fault location list, when two signal towers corresponding to two fault locations are adjacent, the two fault locations form a fault location pair, all fault location pairs in each fault location list are obtained, the absolute value of the distance between the optical fiber attribute information of the two fault locations in each fault location pair is used as the optical fiber attribute information change rate of each fault location pair, and the communication fault state of each fault location is identified based on each fault location list, the optical fiber attribute information change rate of each fault location pair, and the wireless transmission performance of each fault location:

[0058] Where n represents the number of fault locations in the fault location list to which each fault location belongs. The larger the value, the longer the fault duration coordinate at the fault location. j represents the change rate of the fiber attribute information of the j-th fault location pair in the fault location list to which each fault location belongs, It reflects the continuous change of the optical fiber attribute information at the fault location. The larger the value, the more gradual the change of the optical fiber attribute information at the fault location has been. Therefore, the probability that the fault location is caused by the light source failure is higher, so the communication fault state of the fault location is higher. TL represents the wireless transmission performance of each fault location. The larger the value, the more likely the fault location is caused by the movement of the optical fiber, so the communication fault state of the fault location is higher. Max_Min () represents the standardization processing through the maximum and minimum value standardization method. TC represents the communication fault state of each fault location.

[0059] So far, the communication fault status of each fault location is identified through the above process.

[0060] The intercom fault location list acquisition unit 103 identifies the faulty local optical pulses of each fault location list based on the communication fault state of the fault location, and identifies the communication fault confidence of each fault location based on the local optical pulses of each fault location list.

[0061] It should be noted that when the traditional LOF algorithm is used for fault detection, it is generally based on a preset fixed reachable distance to determine the local optical pulse at the fault location. This algorithm can separate outliers, but the faulty fiber attribute information caused by communication factors and the faulty fiber attribute information caused by inappropriate intercom will overlap, that is, the traditional LOF cannot directly distinguish them. In order to distinguish these two types of faulty fiber attribute information, the local optical pulse in the LOF algorithm needs to be corrected according to the communication fault status.

[0062] Specifically, the cumulative sum of the communication fault states of all fault locations in each fault location list is used as the communication fault state of each fault location list, and the closest distance between each fault location list and other fault location lists is calculated. The calculation method for identifying the corrected local optical pulse of each fault location list based on the communication fault state of each fault location list and the closest distance between each fault location list and other fault location lists is as follows:

[0063]

[0064] in, Indicates the communication fault status of each fault location list, d s represents the shortest distance between each fault location list and the sth other fault location list, S represents the number of fault location lists, It represents the corrected local optical pulse of each fault location list. Through this formula, it is possible to correct and identify the corrected local optical pulse of each fault location list according to the communication fault state. exp() represents an exponential function with a natural constant as the base.

[0065] Furthermore, based on the corrected local optical pulse of each fault location list, the fault location list is processed by the LOF algorithm to identify the outlier fault location list and the non-outlier fault location list. Since the fiber attribute information error caused by fiber movement and light source failure is a low-probability event, the fiber attribute information of the fault location in the outlier fault location list is the fault fiber attribute information caused by communication factors, and the fiber attribute information of the fault location in the non-outlier fault location list is the fault fiber attribute information caused by inappropriate intercom. The non-outlier fault location list is called the intercom fault location list.

[0066] The prompting unit 104 performs prompting based on the non-outlier fault location list.

[0067] Specifically, preset hierarchical thresholds A and B, refer to the fiber attribute information of each coordinate point in the intercom fault location list as intercom fault fiber attribute information, average all intercom fault fiber attribute information to identify the mean value J of intercom fault fiber attribute information, and use the formula Calculate the deviation state of the mean value of the intercom fault fiber attribute information. When the mean deviation state of the intercom fault fiber attribute information is less than or equal to A, issue prompt image a. When the mean value of the intercom fault fiber attribute information is greater than A and less than or equal to B, issue prompt image b. When the mean value of the intercom fault fiber attribute information is greater than B, issue prompt image c. When the intercom fault location list is an empty set, no prompt is issued. B takes 2(e2-e1) as an example for description, and other embodiments may take other values, and this embodiment does not make specific restrictions, wherein e2 and e1 respectively represent the upper limit and lower limit of the preset optical fiber attribute information range, and a, b, and c represent three different preset prompt images. In this embodiment, a, b, and c images are respectively set to "optical fiber attribute information slight fault", "optical fiber attribute information moderate fault", and "optical fiber attribute information severe fault" as an example for description, and other embodiments may take other values, and this embodiment does not make specific restrictions.
