Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of power transmission lines, and in particular to a power transmission line WAPI network cross-tower self-healing method and system. Background Art

[0002] Currently, traditional wireless communications are used in transmission line monitoring, and data transmission relies more on the operator's communication base stations. However, transmission lines are generally located in remote areas in the wild, and there may be no base stations near their power towers or their number is limited, making it difficult to fully cover and effectively monitor and transmit data. If new base stations are added specifically for transmission lines, too much unnecessary equipment cost will be added, and traditional wireless communications that transmit data through the operator's network are difficult to ensure the security of power monitoring data.

[0003] A new solution is proposed in the related art, which is based on the optimized networking of WAPI-supported devices installed on the pole tower to perform monitoring data transmission. This can avoid the problem of relying entirely on the operator's communication base stations and being unable to fully cover effective monitoring. At the same time, there is no need to add new base stations and increase unnecessary base station equipment costs, and it can ensure the security of power monitoring data transmission. However, the WAPI equipment optimization networking method in the related art is complex, such as the use of multi-frequency, multi-channel or multi-RF module networking, which also increases the cost of WAPI equipment. For example, high-frequency connections and low-frequency connections require related hardware such as chip support to increase the cost of WAPI equipment.

[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] It should be understood that, in the following, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0039] Figure 1The present invention is a flowchart of a WAPI network cross-tower self-healing method for a transmission line according to an embodiment of the present invention, wherein the WAPI network includes a plurality of towers in the transmission line, such as a WAPI network composed of a plurality of WAPI terminals arranged one by one on the towers, wherein the plurality of towers are arranged in sequence, and the topological relationship of the WAPI network is that the plurality of pre-configured WAPI terminals are sequentially communicated and linked. For example, refer to Figure 2 As shown, four towers arranged in sequence are used as an example, but not limited to this; wherein, a WAPI terminal, namely, WAPI terminals 201 to 204, is respectively arranged on the four towers 1 to 4. The WAPI terminals 201 to 204 are sequentially communicated and linked, that is, initially, a WAPI terminal is manually configured to communicate only with the adjacent WAPI terminal, and has no communication link with the next adjacent WAPI terminal. It is understandable that a monitoring terminal such as a temperature, humidity sensor or camera (not shown) can also be respectively arranged on the four towers 1 to 4, and the monitoring terminal can communicate with the WAPI terminal to transmit the monitoring data to the WAPI terminal, and then transmit it to the background management center based on the WAPI network.

[0040] It should be noted that the distance between multiple towers in the power transmission line is usually 40 to 70 meters, but considering safety factors, the distance between two towers of the high-voltage transmission line is currently between 100 meters and 200 meters, which also affects the proposal of the solution of this embodiment, which is described in detail below. The method may include the following steps:

[0041] Step S101: When the target WAPI terminal detects that the first WAPI terminal has not sent monitoring data within a preset time period, the target WAPI terminal sends networking indication information to the second WAPI terminal, where the networking indication information is used to instruct the second WAPI terminal to send networking information to the target WAPI terminal; wherein the target WAPI terminal is one of the multiple WAPI terminals, the first WAPI terminal is any one or more of two WAPI terminals directly communicating with the target WAPI terminal, and the second WAPI terminal is a WAPI terminal directly communicating with the first WAPI terminal.

[0042] Exemplarily, the target WAPI terminal may be WAPI terminal 202, and the preset duration may be set as required. The first WAPI terminal is any one or more of the two WAPI terminals adjacent to the target WAPI terminal, such as WAPI terminals 203 and 201, and the second WAPI terminal is a WAPI terminal adjacent to the first WAPI terminal, such as WAPI terminal 204. That is, if the target WAPI terminal, such as WAPI terminal 202, is taken as the center, the solution of this embodiment can achieve WAPI network healing and recovery in both the front and rear directions after a problem such as a failure or network disconnection occurs in the first WAPI terminal, such as WAPI terminal 203. Among them, a communication link can be established with a second WAPI terminal, i.e., WAPI terminal 204, on tower 4 where a second WAPI terminal, such as WAPI terminal 204, is located, across tower 3 where the first WAPI terminal, such as WAPI terminal 203, is located.

[0043] As mentioned above, the distance between the two towers of the high-voltage transmission line is between 100 meters and 200 meters. The communication distance between two WAPI terminals in the WAPI network is generally between 100 and 300 meters. In indoor closed areas, the communication distance is generally between 76 and 122 meters, and in open areas outdoors, the communication distance can reach about 300 meters. In this embodiment, since the high-voltage transmission line is in the wild, the maximum communication distance between the two WAPI terminals is generally about 300 meters. Therefore, in this embodiment, the target WAPI terminal is set to establish a communication link with the second WAPI terminal on another tower after crossing one tower to heal and restore the WAPI network. If you want to cross two towers, the communication distance is too far. Even if you barely establish a communication link in some cases, the communication link is extremely unstable and unreliable, so it is abandoned.

[0044] The target WAPI terminal establishes a communication link with a second WAPI terminal on another tower across the tower, and the communication distance usually meets the requirements of stable communication, so that the target WAPI terminal can establish a stable and reliable communication link with the second WAPI terminal, thereby improving the reliability of power monitoring data transmission.

[0045] In one example, when the target WAPI terminal detects that the first WAPI terminal has not sent monitoring data within a preset time period, it can be considered that a problem has occurred with the first WAPI terminal, such as a failure or network disconnection. At this time, networking indication information can be generated and then sent to the second WAPI terminal. The networking indication information is used to instruct the second WAPI terminal to send networking information to the target WAPI terminal.

[0046] Step S102: the target WAPI terminal receives the networking information sent by the second WAPI terminal, and establishes a WAPI communication link with the second WAPI terminal based on the networking information.

[0047] Exemplarily, after the target WAPI terminal receives the networking information sent by the second WAPI terminal, it can establish a WAPI communication link with the second WAPI terminal based on the networking information to heal and restore the WAPI network. The solution of this embodiment can achieve WAPI network healing and recovery in both the forward and reverse directions after a problem occurs in the first WAPI terminal, such as a failure or network disconnection. Compared with WAPI network healing and recovery in one direction, the reliability of power monitoring data transmission can be further improved.

[0048] The above scheme of the embodiment of the present disclosure is based on the actual arrangement of the towers in the transmission line, and multiple WAPI terminals are arranged one by one on multiple towers to form a WAPI network. Since multiple towers are usually arranged in sequence, the topological relationship of the WAPI network is pre-set to be the relationship between multiple WAPI terminals communicating and linking in sequence, which makes the networking method of the multiple WAPI terminals extremely simple and does not bring about the problem of increased cost of WAPI terminals in related technologies. At the same time, the network topological relationship formed by its simple networking method is simple. When a problem occurs in a certain WAPI terminal, the above scheme can timely and accurately find the problematic terminal and restore the WAPI network with bidirectional self-healing, thereby facilitating the timely transmission of power monitoring data and improving the reliability of power monitoring data transmission. That is, the scheme of this embodiment can realize the timely and reliable transmission of power monitoring data based on the WAPI network at a low cost.

[0049] In order to transmit the power monitoring data more timely, illustratively, in one embodiment, the preset duration T is less than 40 milliseconds, that is, T < 40 milliseconds. The value of T can be less than or equal to 20 milliseconds, such as 10 milliseconds, 20 milliseconds, etc. The delay of 4G communication is usually 40 milliseconds on average, so in this embodiment, the preset duration T is set to be less than 40 milliseconds, that is, the delay requirement that is better than 4G communication is basically achieved. By setting the requirement that the WAPI terminal sends monitoring data within the preset duration, such as 20 milliseconds, if it is not sent, it is considered to be a fault or disconnected from the network, so as to promptly and quickly find the problem terminal such as the first WAPI terminal, and then promptly establish a communication link with the second WAPI terminal to restore communication, so that the power monitoring data can be transmitted more timely.

[0050] In one embodiment, the networking information includes at least a unique identifier and a network status of the second WAPI terminal; establishing a WAPI communication link with the second WAPI terminal based on the networking information in step S102 may specifically include: the target WAPI terminal generates a networking request signal based on the unique identifier and the network status of the second WAPI terminal, sends the networking request signal to the second WAPI terminal, receives a networking response signal returned by the second WAPI terminal, and establishes a WAPI communication link with the second WAPI terminal based on the networking response signal.

[0051] Exemplarily, the unique identifier may be a terminal unique ID, a MAC address, a terminal name, etc. The network status may be status information such as whether the network of the second WAPI terminal is busy or idle. When the network status of the second WAPI terminal is idle, the target WAPI terminal generates the networking request signal and sends it to the second WAPI terminal. The second WAPI terminal generates a networking response signal based on the networking request signal, and returns the networking response signal to the target WAPI terminal. The target WAPI terminal establishes a WAPI communication link with the second WAPI terminal based on the networking response signal, such as connecting to each other after performing WAPI two-way authentication. In this way, a stable and reliable communication link can be established through self-healing recovery, thereby improving the reliability of power monitoring data transmission.

[0052] Based on any of the above implementations, combined with reference Figure 3 As shown, in one embodiment, the method may further include the following steps:

[0053] Step S301: Acquire the networking information of the multiple WAPI terminals.

[0054] Exemplarily, the networking information of each WAPI terminal may include a unique identifier of the WAPI terminal and a network status. The network status may include status information such as whether the network of the WAPI terminal is busy or idle, which may be specifically represented by a network resource occupancy rate. For example, if the network resource occupancy rate is greater than or equal to a preset resource threshold, the network is considered busy, and if the network resource occupancy rate is less than a preset resource threshold, the network is considered idle. The preset resource threshold may be set according to specific circumstances, and there is no limitation on this.

[0055] Step S302: When a network failure occurs in the WAPI network, link status information of the communication links between the multiple WAPI terminals is obtained.

[0056] Exemplarily, the communication links between the multiple WAPI terminals may be communication links between two adjacent WAPI terminals, and the link status information of each communication link may include specific link status information such as signal strength, signal-to-noise ratio, and bit error rate.

[0057] Step S303: Analyze and determine the cause of the network failure and / or the identifier of the failed WAPI terminal based on the link status information and the networking information of the multiple WAPI terminals.

[0058] As an example, a link status indication parameter is calculated based on the link status information of each communication link, such as signal strength, signal-to-noise ratio and bit error rate. The link status indication parameter represents the link quality of the communication link, and the link status indication parameter is positively correlated with the link quality.

[0059] Compare the size of the link status indication parameter corresponding to each of the above communication links, select two WAPI terminals associated with the communication link corresponding to the smallest link status indication parameter, and determine the cause of the network failure and / or the faulty WAPI terminal identifier based on the unique identifier and network status in the networking information of the two WAPI terminals. For example, before the network failure occurs, the network status in the networking information of the two WAPI terminals is idle and busy, respectively, then the WAPI terminal in the busy state is determined as the faulty WAPI terminal; if both are busy, then the two WAPI terminals are determined to be faulty WAPI terminals; if both are idle, then the cause of the network failure is determined to be a network signal failure. That is to say, in the networking stage before the network failure occurs, the network status of the faulty WAPI terminal is busy, so at this time, the communication link after networking is likely to be unstable, that is, prone to problems, and when the network failure occurs, the two WAPI terminals associated with the communication link with the worst link quality determined based on the link status information include the faulty WAPI terminal, then the faulty WAPI terminal can be used as the terminal with the greatest possible failure, so it is determined to be a faulty WAPI terminal.

[0060] The above scheme of this embodiment can accurately determine the cause of the network fault of the transmission line WAPI network and / or the faulty WAPI terminal, so that the problematic WAPI terminal can be found in time and accurately to facilitate maintenance personnel to repair or replace the terminal equipment in time.

[0061] In one embodiment, the link status indication parameter is calculated based on the link status information of each communication link, such as signal strength, signal-to-noise ratio and bit error rate, including: weighted summing the signal strength, signal-to-noise ratio and bit error rate corresponding to each communication link with the corresponding preset weight to obtain the link status indication parameter. The weights corresponding to the signal strength, signal-to-noise ratio and bit error rate are different and can be preset. In this way, the network fault cause and / or faulty WAPI terminal of the transmission line WAPI network can be determined more accurately, so that the problem WAPI terminal can be discovered in time and accurately to facilitate maintenance personnel to repair or replace the terminal equipment in time.

[0062] In one embodiment, the method may further include: when the target WAPI terminal detects that the first WAPI terminal has not sent monitoring data within the preset time period, sending status indication information to the second WAPI terminal, the status indication information is used to instruct the second WAPI terminal to send its own working status information to the target WAPI terminal; the target WAPI terminal receives the working status information sent by the second WAPI terminal, and determines whether to send the networking indication information to the second WAPI terminal based on the working status information.

[0063] Exemplarily, in one embodiment, the working state information may include at least any one of idle state information, normal state information, alarm state information, and busy state information. That is to say, in some cases, when the target WAPI terminal detects that the first WAPI terminal has not sent monitoring data within a preset time period, such as when a fault occurs, the second WAPI terminal may not necessarily be ready to establish a communication link with the target WAPI terminal, such as when it is in a busy state and it is inconvenient to establish a communication link in time. Therefore, at this time, the state indication information may be sent to the second WAPI terminal first, and the state indication information indicates that the second WAPI terminal sends its own working state information to the target WAPI terminal. The target WAPI terminal receives the working state information sent by the second WAPI terminal, and determines whether to send the networking indication information to the second WAPI terminal based on the working state information. For example, when the working state information indicates that the second WAPI terminal is in an idle state or a normal state, the networking indication information may be sent to the second WAPI terminal to complete the networking, and when the working state information indicates that the second WAPI terminal is in an alarm or a busy state, the networking indication information may not be sent temporarily.

[0064] In one embodiment, the method may also include: the target WAPI terminal receives the monitoring data sent by the monitoring terminal, and transmits the monitoring data to the background management center through the WAPI network; wherein the monitoring terminal is pre-set on the tower where the target WAPI terminal is located, and establishes a communication link with the target WAPI terminal.

[0065] Exemplarily, the monitoring terminals on each tower can support WAPI technology, establish communication links with the WAPI terminals on the towers where they are located, transmit the collected monitoring data to the corresponding WAPI terminals, and then transmit the monitoring data to the background management center through the WAPI network. For example, 4G or 5G terminals can also be set at the towers at both ends of multiple towers arranged in sequence in a monitoring area. The 4G or 5G terminals are connected to the base stations of the operators to remotely transmit the monitoring data to the background management center through the 4G network or 5G network, so as to facilitate real-time monitoring and management of the monitoring area of ​​the transmission line.

[0066] It should be noted that, although the steps of the method in the present disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution, etc. In addition, it is also easy to understand that these steps may be, for example, executed synchronously or asynchronously in multiple modules / processes / threads.

[0069] The networking module 402 is configured to enable the target WAPI terminal to receive the networking information sent by the second WAPI terminal, and to establish a WAPI communication link with the second WAPI terminal based on the networking information.
