Description

Technical Field

[0001] The utility model relates to the technical field of cables, and particularly relates to a node collector, a front-end edge computing device and a platform. Background Art

[0002] After the construction of the fiber optic network is completed, a ring network is formed, and each ring network is interconnected, as Figure 1 shown. Figure 1 Fig. shows a schematic structural diagram of a fiber optic network. The fiber optic network includes a backbone layer, an aggregation layer and an access layer. A plurality of nodes are arranged in each of the backbone layer, the aggregation layer and the access layer. The nodes in the backbone layer, the aggregation layer and the access layer are respectively represented as Ax, Bx and Cx. Figure 1 In, there are four nodes in the backbone layer, which are respectively represented as A1, A2, A3 and A4. There are seven nodes in the aggregation layer and the access layer respectively, which are correspondingly represented as B1, B2, B3, B4, B5, B6, B7, C1, C2, C3, C4, C5, C6 and C7.

[0003] The existing passive optical fiber network adopts a ring network and an inter-ring interconnection architecture to ensure reliable operation. As Figure 2 shown, A / B / C is a ring network, and A / B / C is interconnected through a dotted line. Therefore, the starting node and the ending node will pass through machine rooms at different levels and different positions for complex network connections. The network path from the starting node to the final node is the route.

[0004] Currently, the testing of the route is mainly realized based on active technologies such as OTDR (Optical Time Domain Reflectometry) and acoustic vibration technology. That is, the device actively sends test light waves and sound waves. The active technology first appeared to find fault points of faulty cables. Therefore, for route survey and analysis, it can be seen from its principle that there are great limitations. At the same time, the above technologies are also affected by the transmitting power and receiving sensitivity of the device. If the distance between the starting node and the ending node exceeds a certain distance, the test cannot be carried out or the test data will have large errors. At the same time, since OTDR or similar active light detection technologies also have an adverse impact on the receivers in the optical network, continuous long-term use will greatly affect the service life of the optical receiving module.

[0045] Embodiment 1:

[0046] The embodiment of the present utility model provides a node collector, as Figure 3 shown. The node collector 100 includes an optical splitter 101. The optical splitter 101 is installed in the node 102 and accesses the communication link 103 of the node 102. The optical splitter 101 has an input end 1011 and two output ends. The two output ends are a first output end 1012 and a second output end 1013 respectively. The service optical signal in the communication link of the node 102 enters the optical splitter 101 through the input end 1011 and returns to the communication link 103 through the first output end 1012. The second output end 1013 is used to output monitoring light, and the monitoring light is the service optical signal collected by the optical splitter 101 from the communication link.

[0047] Exemplarily, the optical splitter 101 can be installed in the node 102 through the ODF frame. One optical splitter 101 is installed in one node 102. During the construction of each node 102, one optical splitter 101 is correspondingly installed. During the actual operation of the optical fiber network, according to the actual situation, the optical splitter 101 can be started to collect the service optical signals of the communication link 103 corresponding to the node 102, so as to obtain the monitoring light, and the monitoring light carries the optical network parameters of the node 102. The real-time online acquisition of optical network parameters (service optical power, whether the service is running) is realized without changing the existing optical network structure and without interrupting the operation of the optical network. The optical splitter 101 can be, for example, an intelligent optical switch capable of realizing link switching, an optical switching matrix, etc., which mainly splits the service optical signals and obtains a part of the light source for online monitoring without affecting the service light.

[0048] In some embodiments, as Figure 4 shown, a photodetector 104 can be connected to the second output terminal 1013, where the photodetector 104 is used to convert the monitoring light into an electrical signal to facilitate the extraction of the optical network parameters of the monitoring light. Of course, the photodetector 104 in the node collector 100 is not necessary, and the photodetector 104 can also be configured in the data processing device connected to the node collector 100.

[0049] Embodiment 2:

[0050] The embodiment of the present invention provides a front-end edge computing device, as Figure 5 shown, the front-end edge computing device 200 includes the node collector 100 and the edge computing module 210 as described above, and the edge computing module 210 is signal-connected to at least one of the node collectors 100.

[0051] It should be noted that one edge computing module 210 can be connected to at least one node collector 100, that is, the monitoring light collected by multiple node collectors 100 can be processed by one edge computing module 210.

[0052] In some embodiments, as Figure 6 shown, the edge computing module 210 includes a preprocessing circuit 211, an analog-to-digital converter 212, a central processing unit 213, and a memory 214. The signal output terminal of the photodetector 104 is connected to the input terminal of the preprocessing circuit 211, the output terminal of the preprocessing circuit 211 is connected to the central processing unit 213 through the analog-to-digital converter 212, and the central processing unit 213 is electrically connected to the memory 214.

[0053] Among them, the preprocessing circuit 211 is used to preprocess the electrical signal converted by the photodetector 104. The processed electrical signal is converted into a digital signal by the analog-to-digital converter 212 and fed to the central processing unit 213. The central processing unit 213 is used to process the digital signal. The data processing mainly includes judging the service optical state in the node. For example, a threshold is set. If the digital signal in the central processing unit 213 is less than the threshold, it is determined that there is no service optical signal in the node. If the digital signal in the central processing unit 213 is within the threshold range, it is determined that the service optical signal in the node is normal. If the digital signal in the central processing unit 213 is greater than the threshold, it is determined that the service optical signal in the node is abnormal. Among them, the digital signal in the central processing unit 213 is the power data corresponding to the monitored light collected. The power of the light is usually determined by the energy of the light, and the energy of the light will be determined by the electrical signal parameters converted by the corresponding light. Therefore, the corresponding digital signal obtained after analog-to-digital conversion after preprocessing the electrical signal is the electrical signal parameter. The central processing unit 213 can calculate the power data of the light based on these electrical signal parameters. The specific calculation method is the prior art and will not be elaborated in detail here in this embodiment. The calculation result of the central processing unit 213 is stored in the memory 214. At the same time, the memory 214 also stores the signal data (such as electrical signals) collected by the node collector 100.

[0054] In some embodiments, the preprocessing circuit 211 is mainly used to filter the electrical signal to remove interference signals, such as Figure 7 As shown, the preprocessing circuit 211 includes a gain control circuit 2111, a noise suppression circuit 2112, a filtering circuit 2113, a shaping circuit 2114, a compensation circuit 2115, and a bias circuit 2116 connected in sequence.

[0055] In some embodiments, such as Figure 6 As shown, the edge computing module 210 further includes a communication module 215. The communication module 215 is electrically connected to the central processing unit 213. The calculation result of the central processing unit 213 can be wirelessly transmitted in real time through the communication module 215. The communication module 215 can be, for example, a wireless transmission module such as a 4G module or a 5G module.
