Description

Technical Field

[0001] The present invention relates to the technical field of industrial monitoring, and specifically to an industrial Internet switching management system and method based on 5G communication. Background Art

[0002] Currently, in the thermoelectric industry field, there is no corresponding equipment for judging 5G network communication faults and automatically switching between 5G and wired networks. Manual switching is required, and manual operation is needed on-site to switch the 5G network to the wired network, with extremely low timeliness. It takes at least five minutes at the fastest, posing a great hidden danger to high-timeliness production monitoring. Summary of the Invention

[0003] The purpose of the present invention is to provide an industrial Internet switching management system and method based on 5G communication to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An industrial Internet switching management system based on 5G communication, including a network status monitoring module, a network switching module, a network management module, a communication module, and an application module; the network status monitoring module is composed of sub-units, and the sub-units include sensors and 5G communication modules; the sensors are used to obtain on-site data in the factory, and the 5G communication modules are used to collect network status information of the sub-units and identify faulty sub-units; the network switching module is used to switch the factory network from a 5G network to a wired network; the network management module, based on the network status of the sub-units, when a 5G network fault occurs, generates a synchronous switching signal to the network switching module, and switches the network from the 5G network to the wired network through synchronous switching; the communication module is used to achieve interconnection between the 5G network and the wired network; the application module is used to provide in-factory business applications and display the network switching results.

[0005] Specifically, the network management module further includes a clustering unit, a coordinate unit, a distribution analysis unit, a time analysis unit, and an interference analysis unit. The clustering analysis unit divides the faulty sub-units into different clustering clusters based on the location information of the faulty sub-units; the coordinate unit is used to establish a spatial rectangular coordinate system within the factory area; the analysis unit is used to analyze the distribution of the faulty sub-units within the factory area; the time analysis unit is used to analyze the time concentration of the faulty sub-units; the interference analysis unit is used to analyze the impact of interference on the 5G network.

[0006] Specifically, the distribution analysis unit obtains the probability of a 5G fault based on the area ratio occupied by the faulty sub-units and combines historical 5G fault data to determine whether the distribution status of the faulty sub-units meets the preconditions for 5G network faults.

[0007] Specifically, the network switching module further includes a delay unit and a switching unit. The delay unit is used to set a delay switching time for staggered switching; the switching unit is used to switch the 5G network to a wired network.

[0008] To achieve the above object, the present invention provides the following technical solutions: An industrial Internet switching management method based on 5G communication, comprising the following steps:

[0009] S11, monitor the status of the subunits in the factory area, and obtain the location information, fault time information, and fault type information of all faulty subunits;

[0010] S12, analyze the location information of the faulty subunits, and determine whether the distribution of the faulty subunits in the factory area meets the preconditions for a 5G network fault. If it meets the preconditions for a 5G network fault, then enter step S13 to analyze the concentration and interference of the faulty subunits; if it does not meet the preconditions for a 5G network fault, then perform a staggered switching between the 5G network and the wired network, maintain the monitoring of the subunits in the factory area, and process the faulty subunits.

[0011] When a 5G network failure occurs, it often means that all or most of the subunits cannot communicate normally, which is a relatively serious situation and will have a great impact on the factory area business. At this time, the primary task is to quickly restore network communication to reduce the losses caused by the interruption of the factory area business. Synchronous switching can quickly switch the network from the unavailable 5G to the wired network, restore communication in a timely manner, and avoid greater harm caused by the continuous 5G network failure; at the same time, since synchronous switching operation is relatively simpler and more direct than staggered switching and does not need to consider complex time delay settings and coordination issues like staggered switching, in a fault state, the system may already be in an unstable or chaotic state, and simplifying the operation can reduce the probability of errors or abnormalities during the switching process, which is more conducive to quickly achieving network switching and enabling the system to return to an available state as soon as possible, while complex synchronous switching may be difficult to achieve under such conditions; after a 5G fault occurs, the system needs to quickly return to a stable operating state. Synchronous switching can enable all subunits to switch to the wired network simultaneously, and uniformly reconstruct and configure the network connections, which is conducive to the overall quick recovery and stable operation of the system.

[0012] When there is no 5G network failure, only normal staggered switching is required, because synchronous switching will cause an instantaneous network interruption, resulting in various automatic exits or disturbances, which will instead cause more serious consequences to the factory area business.

[0013] S13. Analyze the concentration of the faulty subunit based on the location information, fault time information, and fault type information of the faulty subunit. If the concentration meets the requirements of 5G network faults and there is no interference, perform synchronous switching between the 5G network and the wired network; if the concentration does not meet the requirements of 5G network faults or there is interference, perform staggered switching between the 5G network and the wired network to maintain monitoring of the subunits within the plant area.

[0014] Specifically, in step S12, the determination of whether the distribution status of the faulty subunits in the plant area meets the preconditions for 5G network faults further includes the following steps:

[0015] Set a starting point and coordinate axes within the plant area to establish a three-dimensional rectangular coordinate system, and obtain the location information of all subunits.

[0016] Preferably, obtain the location information of all faulty subunits, perform DBSCAN clustering, and set the neighborhood radius r and the minimum number of points mpt.

[0017] Step 1: Select an unvisited faulty subunit as the starting point.

[0018] Step 2: Centered on the selected faulty subunit, search for faulty subunits within the neighborhood radius r.

[0019] Step 3: If the number of faulty subunits found within the neighborhood radius r is not less than the minimum number of points mpt, mark the selected point as a core point and form a clustering cluster with this core point; if the number of faulty subunits found within the neighborhood radius r is less than the minimum number of points mpt, mark this point as a noise point.

[0020] Step 4: For core points, add all faulty subunits within the neighborhood radius r centered on the core point to the clustering cluster formed by the core point; for the faulty subunits added to the core point clustering cluster, determine whether they are core points according to step 3. If they are core points, continue to expand the clustering cluster; if they are not core points, do not expand.

[0021] Repeat steps 1 to 4 until all faulty subunits have been visited.

[0022] Obtain the centroid positions of all clustering clusters after DBSCAN clustering, and the maximum distance rm between the centroid and the corresponding core point in each clustering cluster; with the centroid of the clustering cluster as the center of the sphere and rm + r as the radius, obtain the spherical model of the clustering cluster; obtain the volume of the overlapping area between the spherical models of all clustering clusters and the plant area, and calculate the spatial dispersion sd of the faulty subunits, sd = sq1 / sq2, where sq1 is the volume of the overlapping area between the spherical models of all clustering clusters and the plant area, and sq2 is the total volume of the plant area.

[0023] The minimum number of points mpt is used to control the number of faulty sub-units that trigger network switching. Only when the number of faulty sub-units is sufficient can the requirement of the minimum number of points be met within the neighborhood radius of the faulty sub-units;

[0024] Since 5G signals are wireless signals with regional coverage, when a 5G network fails, it is impossible for a single sub-unit to fail. Basically, all sub-units have communication failures. Therefore, logically, the judgment method is that when a sufficient number of faulty sub-units have communication failures, it is judged as a failure; however, there are also cases where local interference or other factors cause faulty sub-units to be concentrated. Simply judging based on the quantity is likely to yield incorrect results; if the faulty sub-units are widely distributed within the network coverage area without a concentrated trend, this indicates that the failure is not caused by local problems but is a systematic failure of the 5G network, causing sub-units in different regions to be affected simultaneously. This judgment conforms to the general logic of network failures and is used as a prerequisite for judging 5G network failures;

[0025] Specifically, in step S12, the judgment of whether the distribution status of the faulty sub-units in the factory area meets the prerequisite requirements for 5G network failures further includes the following steps:

[0026] Obtain the historical data of 5G network failures within the factory area, determine the volume of the area affected by the 5G network failure, and obtain the spatial dispersion of the 5G network failure based on the affected area volume; based on the spatial dispersion of the faulty sub-units, obtain the probability P{C≥sd} of a 5G network failure, where C represents the spatial dispersion random variable, and P{C≥sd} = n1 / n2. Here, n2 represents the number of historical data when the spatial dispersion of the faulty sub-units within the factory area is greater than or equal to sd, and n1 represents the number of historical data when a 5G network failure causes the spatial dispersion of the faulty sub-units within the factory area to be greater than or equal to sd; if the probability P{C≥sd} of a 5G network failure is greater than the threshold, it meets the prerequisite requirements for 5G network failures, otherwise it does not meet the prerequisite requirements for 5G network failures.

[0027] Specifically, in step S13, it further includes the following steps:

[0028] Obtain the time information of all faulty sub-units when they fail, arrange the failure times in ascending order, calculate the time difference between the latter item and the former item in the arrangement, and obtain the average value T of all time differences; if the average value T of all time differences is not less than the time threshold, it does not meet the concentration requirement of 5G network failures; if the average value T of all time differences is less than the time threshold, it meets the concentration requirement.

[0029] Widely distributed faulty subunits are not necessarily exactly the same as network failures. It is possible that multiple subunits simultaneously experience independent random failures, or it could be large electromagnetic devices within the factory area, whose generated strong electromagnetic interference centrally affects the surrounding subunits, resulting in communication failures, or there could be a situation where both interference and random independent failures exist. Further analysis is carried out on the basis of meeting the preconditions.

[0030] 5G network failures usually occur suddenly at a certain moment, and the affected subunits will exhibit failure phenomena almost simultaneously, with strong temporal synchrony; when multiple subunits simultaneously experience independent random failures, although they occur simultaneously, there may be a certain sequence in time, but they occur concentrated within a relatively short time range, not at exactly the same moment.

[0031] Specifically, in step S13, the following steps are also included:

[0032] Obtain the failure types of all faulty subunits, and sort the failure types by severity and assign labels. The higher the severity, the larger the value of the label;

[0033] Record the devices within the factory area that can generate electromagnetic interference as interference devices, and obtain the location information of the interference devices; take the interference devices as the center and generate concentric rings outward, with the distance R between the ring edges and the center increasing step by step; obtain the failure types of the faulty subunits within each ring, calculate the average value AL of the labels of all faulty subunits within the same ring, and obtain the corresponding relationship between the label average value AL and the distance R; obtain the number of faulty subunits within each ring, calculate the proportion POR of the faulty subunits in each ring among all the subunits within the ring, and obtain the corresponding relationship between the proportion POR and the distance R;

[0034] Analyze whether AL and POR decrease as the distance R increases. If so, it indicates that there is an influence from interference devices; if not, it is judged as a 5G network failure.

[0035] For example, the subunit failure types include but are not limited to increased latency, packet loss, and disconnection, with the severity increasing step by step; the assigned label values also increase step by step; the electromagnetic devices existing within the factory area, whose generated electromagnetic interference will centrally affect the surrounding subunits in the surrounding space, and the degree of influence weakens as the physical distance increases. This influence is not based on the network logical structure and is only affected by the distance in physical space.

[0036] Specifically, the time - staggered switching between the 5G network and the wired network specifically includes the following steps:

[0037] There are two networks, Network A and Network B. Both networks include a 5G switch and a wired switch. Network A switches from the 5G switch to the wired switch, and after a delay time t, Network B then switches from the 5G switch to the wired switch;

[0038] The synchronous switching of the 5G network and the wired network specifically includes the following steps:

[0039] Cancel the delay time t, and both Network A and Network B switch from the 5G switch to the wired switch simultaneously.

[0040] Compared with the prior art, the beneficial effects of the present invention are: analyzing the spatial distribution status of the faulty sub-units as a precondition for 5G network fault judgment; further analyzing the concentration and interference of the faulty sub-units to reduce the possibility of misjudging 5G network faults and mitigate the impact on the operation of the factory area; being able to automatically judge the 5G network status, realizing the switching between the 5G network and the wired network, ensuring the security of the DCS network, and ensuring the stability of production equipment monitoring.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment: As Figure 1As shown in the figure, the present invention provides a technical solution, an industrial Internet switching management system based on 5G communication, including a network status monitoring module, a network switching module, a network management module, a communication module, and an application module; the network status monitoring module consists of subunits, and the subunits include sensors and 5G communication modules; the sensors are used to obtain on-site data in the factory, and the 5G communication modules are used to collect the network status information of the subunits and identify the faulty subunits; the network switching module is used to switch the factory network from the 5G network to the wired network; the network management module, based on the network status of the subunits, when a 5G network failure occurs, generates a synchronous switching signal to the network switching module, and switches the network from the 5G network to the wired network through synchronous switching; the communication module is used to realize the interconnection between the 5G network and the wired network; the application module is used to provide in-factory business applications and display the network switching results.

[0045] Specifically, the network management module further includes a clustering unit, a coordinate unit, a distribution analysis unit, a time analysis unit, and an interference analysis unit. The clustering analysis unit divides the faulty subunits into different clustering clusters based on the location information of the faulty subunits; the coordinate unit is used to establish a spatial rectangular coordinate system within the factory area; the analysis unit is used to analyze the distribution of the faulty subunits within the factory area; the time analysis unit is used to analyze the time concentration of the faulty subunits; the interference analysis unit is used to analyze the impact of interference on the 5G network.

[0046] Specifically, the distribution analysis unit obtains the probability of a 5G failure based on the area ratio occupied by the faulty subunits and combines historical 5G failure data to determine whether the distribution status of the faulty subunits meets the preconditions for a 5G network failure.

[0047] Specifically, the network switching module further includes a delay unit and a switching unit. The delay unit is used to set a delay switching time for staggered switching; the switching unit is used to switch the 5G network to the wired network.

[0048] Embodiment: The present invention provides a technical solution, an industrial Internet switching management method based on 5G communication, including the following steps:

[0049] S11, monitor the status of the subunits in the factory area, and obtain the location information, fault time information, and fault type information of all faulty subunits;

[0050] S12. Analyze the location information of the faulty sub-units, and determine whether the distribution status of the faulty sub-units in the factory area meets the preconditions for 5G network faults. If it meets the preconditions for 5G network faults, then proceed to step S13 to analyze the concentration and interference of the faulty sub-units; if it does not meet the preconditions for 5G network faults, then perform a time-sharing switch between the 5G network and the wired network, maintain the monitoring of the sub-units in the factory area, and handle the faulty sub-units.

[0051] The determination of whether the distribution status of the faulty sub-units in the factory area meets the preconditions for 5G network faults further includes the following steps:

[0052] Set a starting point and coordinate axes inside the factory area, establish a space rectangular coordinate system, and obtain the location information of all sub-units.

[0053] Obtain the location information of all faulty sub-units, perform DBSCAN clustering, and set the neighborhood radius r and the minimum number of points mpt.

[0054] Step 1: Select an unvisited faulty sub-unit as the starting point.

[0055] Step 2: With the selected faulty sub-unit as the center, search for the faulty sub-units within the neighborhood radius r.

[0056] Step 3: If the number of faulty sub-units found within the neighborhood radius r is not less than the minimum number of points mpt, then mark the selected point as a core point and form a cluster with this core point; if the number of faulty sub-units found within the neighborhood radius r is less than the minimum number of points mpt, then mark this point as a noise point.

[0057] Step 4: For the core points, add all the faulty sub-units within the neighborhood radius r centered on the core points to the cluster formed by the core points; for the faulty sub-units added to the core point cluster, determine whether they are core points according to step 3. If they are core points, then continue to expand the cluster; if they are not core points, then do not expand.

[0058] Repeat steps 1 to 4 until all faulty sub-units have been visited.

[0059] Obtain the centroid positions of all clusters after DBSCAN clustering, and the maximum distance rm between the centroid and the corresponding core point in each cluster; with the centroid of the cluster as the center of the sphere and rm + r as the radius, obtain the spherical model of the cluster; obtain the volume of the overlapping area between the spherical models of all clusters and the factory area, and calculate the spatial dispersion sd of the faulty sub-units, where sd = sq1 / sq2, where sq1 is the volume of the overlapping area between the spherical models of all clusters and the factory area, and sq2 is the total volume of the factory area.

[0060] In terms of the clustering effect, the neighborhood radius r and the minimum point number parameter usually need to be tried and adjusted multiple times. Different combinations of the neighborhood radius r and the minimum point number can be tried, and the changes in the clustering results can be observed. In terms of 5G fault detection, in order to reduce false alarms, the minimum point number can be increased, and in order to increase the 5G fault detection rate, the minimum point number can be reduced.

[0061] Obtain the historical data of 5G network faults occurring inside the factory area, determine the volume of the area affected by the 5G network fault, and obtain the spatial dispersion of the 5G network fault based on the affected area volume. Based on the spatial dispersion of the fault sub-units, obtain the probability P{C≥sd} of the occurrence of the 5G network fault, where C represents the spatial dispersion random variable, and P{C≥sd} = n1 / n2. Here, n2 represents the number of historical data when the spatial dispersion of the fault sub-units inside the factory area is greater than or equal to sd, and n1 represents the number of historical data when the occurrence of the 5G network fault causes the spatial dispersion of the fault sub-units inside the factory area to be greater than or equal to sd. If the probability P{C≥sd} of the occurrence of the 5G network fault is greater than the threshold, the pre-requisite requirements for the 5G network fault are met; otherwise, the pre-requisite requirements for the 5G network fault are not met.

[0062] In the historical data of 5G network faults occurring inside the factory area, the spatial dispersion can also be determined in the above manner. If the scope affected by the 5G network fault is clear, the spatial dispersion can be directly determined based on the affected scope.

[0063] S13. Analyze the concentration of the fault sub-units based on the location information, fault time information, and fault type information of the fault sub-units:

[0064] Obtain the time information of all fault sub-units when faults occur, arrange the fault times in ascending order, calculate the time difference between the latter item and the former item in the arrangement, and obtain the average value T of all time differences. If the average value T of all time differences is not less than the time threshold, the concentration requirement for the 5G network fault is not met; if the average value T of all time differences is less than the time threshold, the concentration requirement is met.

[0065] Obtain the fault types of all fault sub-units, sort the fault types according to the severity level and assign labels. The higher the severity level, the larger the value of the label;

[0066] Denote the equipment that can generate electromagnetic interference inside the factory area as interference equipment, and obtain the location information of the interference equipment; taking the interference equipment as the center, generate concentric circles outward, and the distance R between the edge of the circle and the center increases step by step; obtain the fault types of the faulty sub-units within each circle, calculate the average value AL of the labels of all faulty sub-units within the same circle, and obtain the corresponding relationship between the label average value AL and the distance R; obtain the number of faulty sub-units within each circle, calculate the proportion POR of the faulty sub-units in each circle among all the sub-units within the circle, and obtain the corresponding relationship between the proportion POR and the distance R.

[0067] Analyze whether AL and POR decrease as the distance R increases. If so, it indicates that there is an influence from interference equipment; if not, it is judged as a 5G network fault.

[0068] To analyze the trend of AL and POR with respect to the change in distance R, the least squares fitting method can be used, that is, taking R as the input and AL or POR as the output, calling the least squares function, and inputting the data into the fitting function. For example, the interference equipment generates 5 concentric circles (the first circle is spherical), with distances R1, R2, R3, R4, and R5 respectively. Within each circle, obtain the average value of the labels of the faulty sub-units to get AL1 to AL5. Then, place AL1 to AL5 at the input and R1 to R5 at the output, train the coefficients of the least squares fitting, obtain the functional relationship of AL with respect to R based on the coefficients, and take the derivative of the functional relationship to determine whether the overall trend of AL decreases as R increases; the same applies to POR; not limited to the least squares fitting, other fitting functions can also be used; or judge whether the overall data shows a downward trend through the chart method.

[0069] If the concentration meets the requirements of 5G network faults and there is no interference, perform synchronous switching between the 5G network and the wired network; if the concentration does not meet the requirements of 5G network faults or there is interference, perform staggered switching between the 5G network and the wired network to maintain monitoring of the sub-units within the factory area.

[0070] The specific steps for performing staggered switching between the 5G network and the wired network are as follows:

[0071] There are two networks, A and B. Both networks include 5G switches and wired switches. Network A switches from a 5G switch to a wired switch, and after a delay time t, network B then switches from a 5G switch to a wired switch.

[0072] The specific steps for performing synchronous switching between the 5G network and the wired network are as follows:

[0073] Cancel the delay time t, and networks A and B simultaneously switch from 5G switches to wired switches.

[0074] Example: As Figure 2 shown, the present invention provides a switch switching control diagram. The switching between the 5G network and the wired network establishes its communication link through the power gain and loss of the switch. First, four physical communication connections of the network are constructed. KA1 and KA2 are physical connection switches, and then the real communication is established through the power gain and loss status of the switch. When synchronous switching is required, the physical connections of network A and network B with the 5G switch are disconnected synchronously, and the physical connections of network A and network B with the wired switch are connected. Then, the real communication is established through the power gain and loss status of the switch.

[0075] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
