[0089] Embodiment one

[0090] Figure 1 A flowchart of a cable data transmission method is provided for the first embodiment of the present application. The method can be performed by a cable data transmission device, which can be realized in the form of hardware and / or software, and can be configured in a collector. As shown in Figure 1 , the method comprises:

[0091] Step 101: Select one of the collectors in the group as a proxy node.

[0092] In this embodiment, as shown in Figure 2 , a plurality of groups of collectors 202 can be deployed according to the geographical position of the cable 200, wherein the collectors have a plurality of sensors inside, and different sensors can be used to collect different state data of the cable.

[0093] For example, the collector is configured with a power frequency sensor, a partial discharge sensor, a traveling wave sensor, and a circulating current sensor. The power frequency sensor can be used to collect the power frequency current signal of the cable, the partial discharge sensor can be used to collect the partial discharge signal of the cable, the traveling wave sensor can be used to collect the traveling wave signal of the cable, and the circulating current sensor can be used to collect the circulating current signal of the cable, etc.

[0094] The collector 202 can be integrally installed in an outdoor cabinet, and is provided with a battery (such as a lithium battery) to provide power for the collector and ensure normal operation of the collector.

[0095] In some designs, the collector is provided with a solar panel to charge the battery.

[0096] As shown in Figure 2 For a group, one collector 202 can be referred to as a monitoring node. If all monitoring nodes are directly connected to the server 201 in the cloud, and the number of monitoring nodes is too large, it will cause the power consumption of the server 201 in the cloud to be too large.

[0097] Therefore, the embodiment can group the monitoring nodes, that is, divide the monitoring nodes into multiple groups. All collectors 202 in the same group belong to the same region in terms of geographical location. The collectors 202 in each group are connected through optical fibers. In a group, one of the collectors 202 is selected as a proxy node. The proxy node is connected to the server 201 in the cloud through a mobile communication network (such as 4G, 5G, etc.). The non-proxy nodes in the group are not connected to the server 201 in the cloud.

[0098] In the same group, a mobile communication module can be provided in some collectors. The mobile communication module is used to provide the communication function of the mobile communication network. One of the collectors is selected as a proxy node. Since the cost of the mobile communication network is higher than the cost of the optical fiber, the overall cost of deploying the collector can be effectively reduced.

[0099] Of course, in addition to providing the mobile communication module in some collectors, the mobile communication module can also be provided in all collectors. The embodiment does not limit this.

[0100] In actual application, the collector may fail, and the quality of the mobile communication network is affected by weather, geographical environment, etc. Therefore, in the same group, one of the collectors can be dynamically selected as a proxy node to improve the efficiency of transmitting the state data of the cable.

[0101] In dynamic selection, each collector in the current group can be traversed.

[0102] If the current collector is updated to a candidate node, the signal quality (such as speed, delay, packet loss rate, etc.) of the current mobile communication network is detected in response to the candidate node. The candidate node is initially the collector located in the middle of the current group. The overall communication path between the collector located in the middle and other collectors is the shortest, which can reduce the transmission delay.

[0103] If the signal quality meets the preset transmission condition (e.g., the packet loss rate is less than a certain threshold, the time delay is less than a certain threshold, etc.), it indicates that the quality of the mobile communication network of the current candidate node is better, and the current collector is set as the proxy node, and the traversal of the collector is stopped.

[0104] If the signal quality does not meet the preset transmission condition (e.g., the packet loss rate is greater than a certain threshold, the time delay is greater than a certain threshold, etc.), it indicates that the quality of the mobile communication network of the current candidate node is poor, and it is not suitable to be set as the proxy node, then other collectors which are adjacent to the current collector in geographical position are searched in the current group, and these other collectors meet the requirements of the proxy node in hardware, that is, the direction of the traversal of the collectors in a group is from the middle to the edge.

[0105] If other collectors which are adjacent to the current collector in geographical position are found in the current group, the current collector is canceled as the candidate node, the other collectors are notified to update as the candidate node, and whether it is suitable to be set as the proxy node is judged.

[0106] If all collectors in the current group are not set as the proxy node, the current group and other groups adjacent to it are merged, that is, the current group and other groups adjacent to it in geographical position are merged into a new group, and the state data of the transmission cable is ensured to be transmitted normally.

[0107] Since the number of collectors in a single group is large, the time delay of the state data of the transmission cable in the group will increase, therefore, the merging of the group is temporary, and when a collector which meets the requirements of the proxy node is detected in the current group, the merging of the group can be canceled.

[0108] Step 102, collecting the state data of the cable.

[0109] During the operation of the collector, the state data of the cable responsible by it can be collected according to the configuration, for example, the power frequency current signal, the partial discharge signal, the traveling wave signal and the circulating current signal, etc.

[0110] In addition, the state data can carry the segment number of the cable, the identifier (e.g., ID, etc.) of the collector, the time stamp and other information.

[0111] Step 103, if the current collector is the proxy node, the time delay of the transmission of the state data between the collectors in the group and the server is calculated.

[0112] In a relatively short time range, the state data collected by the collector on the cable is relatively fixed, and the transmission path between the collector, the proxy node and the server is relatively fixed, therefore, in this case, the time delay of the transmission of the state data between the collectors in the group and the server can be estimated.

[0113] In one embodiment of the present application, step 103 can comprise the following steps:

[0114] Step 1031, calculating the data volume of the state data collected by a single collector.

[0115] Since the state data collected by all collectors on the cable are the same, under the condition that the type of the state data collected by the collector on the cable is stable, the data volume of the state data collected by a single collector can be calculated by statistical methods (such as averaging).

[0116] Step 1032, calculating the first transmission time of the state data transmitted between all collectors in the group and the proxy node through the optical fiber according to the data volume.

[0117] In this embodiment, for a given group, on the basis of the topology between the collector and the proxy node, the first transmission time of the state data transmitted between all collectors in the group and the proxy node through the optical fiber can be evaluated according to the data volume of the state data transmitted once.

[0118] Illustratively, the first transmission time is:

[0119]

[0120] Where t1 is the first transmission time, m is the number of collectors in the group, D is the data volume, v1 is the transmission speed of the optical fiber, and t c is the time compensation coefficient.

[0121] Step 1033, calculating the second transmission time of the state data transmitted between the proxy node and the server through the mobile communication network according to the data volume.

[0122] In this embodiment, for a given group, on the basis of the mobile communication network between the proxy node and the server, the second transmission time of the state data transmitted between the proxy node and the server through the mobile communication network can be evaluated according to the data volume of the state data transmitted once.

[0123] Illustratively, the second transmission time is:

[0124]

[0125] Where t2 is the second transmission time, m is the number of collectors in the group, D is the data volume, and v2 is the transmission speed of the mobile communication network.

[0126] Step 1034, adding the first transmission time and the second transmission time to obtain the time delay of the state data transmitted between the collector in the group and the server.

[0127] In the embodiment, for the same group, the transmission of the state data between the collectors in the group and the server is divided into two parts, one part is the transmission of the state data between all the collectors in the group and the proxy node through the optical fiber, and the other part is the transmission of the state data between the proxy node and the server through the mobile communication network, therefore, the sum of the first transmission time and the second transmission time is the time delay of the transmission of the state data between the collectors in the group and the server.

[0128] Therefore, the time delay is expressed as:

[0129] t = t1 + t2

[0130] Wherein, t is the time delay, t1 is the first transmission time, and t2 is the second transmission time.

[0131] Step 104, receiving the state data collected by other collectors in the group through the optical fiber according to the time delay.

[0132] In practical application, the time delay of the transmission of the state data between the collectors in the group and the server is taken as a reference for the transmission of the state data, and a corresponding threshold value can be set for the time delay, which is generally greater than the time delay and can be applied to the retransmission mechanism, alarm mechanism, etc.

[0133] If the current collector is the proxy node in the group, the state data collected by other collectors in the group except the proxy node for the cable responsible by the proxy node can be received through the optical fiber and written into the cache queue.

[0134] In addition, the time delay is taken as a reference to determine whether to trigger the retransmission mechanism, alarm mechanism, etc.

[0135] Since different types of state data are applied to different ways of cable monitoring, the transmission mode of different types of state data can be different.

[0136] For example, state data such as power frequency current signal, partial discharge signal and traveling wave signal can be used for regular monitoring of the cable, therefore, the collector can transmit these state data to the proxy node through the optical fiber at fixed intervals.

[0137] For another example, state data such as loop current signal can be used for emergency monitoring of the cable, therefore, the collector can transmit these state data to the proxy node through the optical fiber in real time when the state data is collected.

[0138] Step 105, transmitting the state data to the server through the mobile communication network according to the time delay.

[0139] If the current collector is the proxy node in the group, the state data collected by each collector on the cable can be read from the cache queue, and the state data is packaged and transmitted to the server in the cloud through the mobile communication network.

[0140] As shown in Figure 2 The server 201 in the cloud detects the cable using the state data of the cable, evaluates the state of the cable, and the user can log in to the server 201 in the cloud from the electronic equipment such as the personal computer 203 and the mobile terminal 204, and query the state of the related cable according to the user's authority.

[0141] In addition, the time delay is used as a reference to determine whether to trigger a retransmission mechanism, an alarm mechanism, etc.

[0142] In an embodiment of the present application, step 105 can include the following steps:

[0143] Step 1051, set a time threshold for the time delay.

[0144] In this embodiment, the time threshold can be generated by adding a preset time compensation value, multiplying an amplification coefficient greater than 1, etc. on the basis of the time delay.

[0145] Step 1052, determine the data transmission time period.

[0146] In this embodiment, a fixed time can be divided into a data transmission time period in each time period (such as every day), and there is another time period between the adjacent two data transmission time periods. The duration of the other time periods can be equal or not, which is not limited in this embodiment.

[0147] Step 1053, set the antenna of the proxy node as the transmitting end and the antenna of the server as the receiving end in the data transmission time period.

[0148] As shown in Figure 2 If the system time of the proxy node reaches a certain data transmission time period in each time period, the proxy node can apply the SWIPT (Simultaneous Wireless Information and Power Transfer) protocol, set its own antenna 2021 as the transmitting end, and notify the server to set its antenna as the receiving end.

[0149] Step 1054, use the transmitting end to transmit the state data to the receiving end for information decoding within the time threshold through the mobile communication network.

[0150] Generally, the agent node can start timing from the other collector transmitting the state data, and within the time threshold, the state data is transmitted to the receiving end for information decoding (ID) by the transmitting end through the mobile communication network according to the SWIPT protocol, so as to avoid triggering the retransmission mechanism, alarm mechanism and other transmission mechanisms.

[0151] In another embodiment of the application, step 105 can further include the following steps:

[0152] Step 1055, querying the type of the state data in the non-data transmission period.

[0153] If the system time of the agent node reaches the non-data transmission period, that is, the time outside all the data transmission periods, in each time period, the agent node can check the type of each state data in the cache queue according to the preset frequency.

[0154] Step 1056, if the type is not a ring signal, the antenna of the agent node is set as the receiving end, and the antenna of the server is set as the transmitting end.

[0155] As shown in FIG. Figure 2 If the type of all state data in the cache queue of the agent node is not a ring signal, the SWIPT protocol can be applied, the antenna 2021 of the agent node itself is set as the receiving end, and the server is notified to set its antenna as the transmitting end, and waits for triggering the charging operation.

[0156] Further, the agent node can detect the remaining power of the battery in real time, and if the remaining power is lower than the preset power threshold, the SWIPT protocol can be applied, the antenna of the agent node itself is set as the receiving end, and the server is notified to set its antenna as the transmitting end, so as to reduce the frequency of the charging operation.

[0157] Step 1057, using the receiving end to receive the energy signal transmitted by the transmitting end for energy harvesting and charging the battery.

[0158] According to the SWIPT protocol, the agent node can use the receiving end to receive the energy signal transmitted by the transmitting end for energy harvesting (EH) and charging the battery, so as to realize remote charging, improve the simplicity of the charging operation, and effectively reduce the maintenance cost.

[0159] In another embodiment of the application, step 105 can further include the following steps:

[0160] Step 1058, if the type is a ring signal, stop charging the battery.

[0161] If the proxy node finds that the type of the state data in the cache queue is the ring current signal, the charging of the battery can be stopped.

[0162] Step 1059, switching the antenna of the proxy node from the receiving end to the transmitting end, and switching the antenna of the server from the transmitting end to the receiving end.

[0163] As shown in Figure 2 , in general, the number of antennas 2021 of the proxy node is one, therefore, the proxy node can apply the SWIPT protocol, switch its own antenna 2021 from the receiving end to the transmitting end, and notify the server to switch its antenna from the transmitting end to the receiving end, so as to realize the switching between the transmitting end and the receiving end.

[0164] Step 1060, within the time threshold, using the transmitting end to transmit the ring current signal to the receiving end through the mobile communication network for information decoding.

[0165] In general, the proxy node can start timing from the transmission of the ring current signal by other collectors, within the time threshold, according to the SWIPT protocol, using the transmitting end to transmit the ring current signal to the receiving end through the mobile communication network for information decoding ID, avoiding timeout triggering retransmission mechanism, alarm mechanism and other transmission mechanisms.

[0166] The server receives the ring current signal, and can detect the cable in real time to avoid cable failure.

[0167] In this embodiment, one of the collectors in the group is selected as a proxy node; the state data of the cable is collected; if the current collector is the proxy node, the time delay of the transmission of the state data between the collectors in the group and the server is calculated; the state data collected by the other collectors in the group is received through the optical fiber according to the time delay; and the state data is transmitted to the server through the mobile communication network according to the time delay. Selecting one proxy node in a group to connect with the server can effectively reduce the number of connections and reduce the power consumption of the server. When evaluating the time delay of a group, the transmission of the state data is controlled, the actual time delay of the transmission of the state data is reduced as much as possible, and the overall efficiency of the collectors in a group for transmitting the state data is improved.
