[0015] Furthermore, in step S3, the uplink transmission device combines the power data and then extracts the best conversion device combination from the conversion devices based on the split combination mode for split transmission, including the following steps:

[0016] The number of the conversion devices is obtained and defined as a first number. If the first number is equal to 1, the abnormal device is replaced with the conversion device in the connection structure diagram to transmit the power data. If the first number is greater than 1, the conversion device combination is generated based on the first number of the conversion devices, a power data set transmitted by the uplink transmission device to each of the conversion devices and the abnormal device is obtained, each subset data in the power data set is combined according to the first number of the conversion devices to generate the power data combination, and the load data of each of the uplink transmission devices and the conversion devices within a preset time is obtained respectively, the power data combination of the uplink transmission device and the conversion device combination are combined in a shunt combination mode to transmit the power data of the uplink transmission device, and a performance change value y corresponding to the shunt combination mode is calculated based on a second formula so that the performance change value of the conversion device combination is minimized;

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0039] like Figure 1 As shown, a method for monitoring a power system communication network includes:

[0040] Step S1: Set a first time interval, and based on the first time interval, the first monitoring device sends a first detection file to each first communication device in the power system communication network, and the first communication device outputs a first result after receiving the first detection file, and sets the first communication device that does not output the first result as an abnormal device.

[0041] Specifically, in this embodiment, the first monitoring device refers to a cloud-based monitoring device, through which each first communication device in the power system communication network can be monitored. The power system communication network is a network composed of multiple communication methods such as optical fiber, digital microwave and satellite and various communication devices for power system communication. The first communication device refers to a network communication device used for data transmission. The first communication device includes but is not limited to collectors, switches, routers and computer equipment. The first communication device is used to transmit the sensor data of each node in the power system to a control platform or a mobile terminal through the network. For example, the first time interval is set to 10 seconds, and the first monitoring device sends a first detection file to each first communication device every 10 seconds. The first communication device outputs a first result after receiving the first detection file. If the first communication device does not receive the first detection file, that is, the first communication device has a network failure problem, the first communication device with the failure problem will be marked as an abnormal device.

[0042] Step S2: Monitor the power system communication network, obtain the network structure diagram of the power system communication network and the connection structure diagram of the abnormal equipment respectively, and judge the status problem of the abnormal equipment based on the network structure diagram and the connection structure diagram. If the status problem is a first type of problem, execute step S3; if the status problem is a second type of problem, execute step S4.

[0043] Specifically, in this embodiment, if Figure 2 and Figure 3As shown, the network structure diagram refers to the network configuration diagram of the communication route in the power system communication network, the connection structure diagram of the abnormal device refers to the network topology of the abnormal device, which includes the remaining first communication devices that directly communicate with the abnormal device, and the status problem refers to the judgment of the type of reason for the failure of data information transmission of each abnormal device. The status problem includes the first type of problem and the second type of problem. The first type of problem refers to the failure of data information transmission caused by the abnormal device itself, and the second type of problem refers to the disconnection of the communication network used for data information transmission to the abnormal device. Different operation steps are performed according to different status problems to solve the problem of reception failure when the first monitoring device sends the first detection file to the abnormal device.

[0044] Step S3: Based on the connection structure diagram, the uplink transmission device that transmits power data to the abnormal device and the conversion device that exchanges data with the abnormal device are obtained, and the diversion combination method is set. After the uplink transmission device combines the power data, the best conversion device combination is extracted from the conversion device based on the diversion combination method for diversion transmission, and then the conversion device combination continues to transmit to the first communication device.

[0045] Specifically, in this embodiment, the uplink transmission device refers to a first communication device that is adjacent to the abnormal device and transmits data information to the abnormal device, the conversion device refers to a first communication device that can transmit data information to the uplink transmission device, and the network topology structure of the conversion device and the network topology structure of the abnormal device have at least one first communication device that is the same, the power data includes data information transmitted by each uplink transmission device to the abnormal device and each conversion device, and the power data combination refers to arranging and combining the set of power data transmitted to each different device in the uplink transmission device so that the number of subsets in the power data combination is consistent with the number of each conversion device of the uplink transmission device, for example, Figure 2If the abnormal device N fails, data information will no longer be transmitted through it. The power data contained in the uplink transmission device c1 includes power data e1, e2 and e3 transmitted to the conversion device r1, conversion device r2 and abnormal device N respectively. Among them, the uplink transmission device c1 has two conversion devices r1 and r2, so the power data combination is to randomly combine e1, e2 and e3 into two subset combinations. The conversion device combination refers to the permutation and combination between the conversion devices of the uplink transmission device. For example, the uplink transmission device c1 has two conversion devices r1 and r2, so it can be combined into three conversion device combinations: (r1, r2), (r1) and (r2). The diversion combination method refers to a combination method for selecting the best conversion device combination among various conversion devices, and is used to generate a power data combination from the power data of each upstream transmission device through different combination methods and then divert the power data to the conversion device combination, and then the conversion device combination transmits data information to the corresponding first communication device. The data is transmitted to the first communication device W through the conversion device combination. By skipping the abnormal device N, the integrity of the data information is retained and the security of the power system communication network can be enhanced.

[0046] Step S4: Based on the network structure diagram, all communication routes between the abnormal device and the first communication device are obtained, and the best communication route is selected as a backup route. When the abnormal device has the second type of problem, data information is transmitted between the abnormal device and the first communication device through the backup route.

[0047] Specifically, in this embodiment, the communication route refers to the connection route between the abnormal device and each first communication device in the network structure diagram, including but not limited to the optical fiber network and the wireless network. When the status problem of the abnormal device is the second type of problem, the backup route refers to the route with normal communication, which can be used to replace the communication route with the network communication interruption phenomenon in the abnormal device. For example, Figure 3 After the communication route L3 is interrupted, the best communication route can be selected from the communication routes L4 and L5 as a backup route, and the abnormal device N can continue to transmit data information through the backup route.

[0048] The present invention first sets a first time interval so that a first monitoring device sends a first detection file to each first communication device in the power system communication network. The first result output by each first communication device can timely obtain the working status of each first communication device, thereby further monitoring the data transmission status in real time to avoid interruption and loss during the data transmission process; the present invention also marks the first communication device that fails to output the first result as an abnormal device, and then determines the status problem of the abnormal device, and executes different operation steps according to different status problems. When the abnormal device does not handle the fault / when the device is not restored, the power system communication network can be restored to a normal state to transmit data information.

[0049] The present invention also selects the best conversion device combination in the conversion device by setting the diversion combination mode to transmit the power data set to be transmitted in the uplink transmission device corresponding to the abnormal device, thereby improving the safety and reliability of the power system communication network.

[0050] It is particularly noteworthy that the present invention can monitor the power system communication network in real time and solve different types of communication problems, thereby improving the safety and reliability of the power system communication network.

[0051] In step S2, determining the status of the abnormal device includes the following steps:

[0052] The connection structure diagram includes an abnormal device and a first communication device connected to the abnormal device. The first communication device connected to the abnormal device is set as a first connection device. A second time interval is set. The abnormal device sends a second detection file to each first connection device based on the second time interval. The first connection device outputs a second result after receiving the second detection file. If all first connection devices output the second result, the state problem of the abnormal device is set as a first type of problem. If there is at least one first connection device that does not output the second result, the first ratio a is calculated by a first formula. The first formula is: , where n is the number of first connected devices that output the second result, and m is the number of first connected devices that do not output the second result. If the first ratio is greater than or equal to 1, the state problem of the abnormal device is set to the first type of problem, otherwise, the state problem of the abnormal device is set to the second type of problem.

[0053] Specifically, in this embodiment, by determining the status problem of the abnormal device, corresponding measures can be taken to solve the status problem, such as Figure 2As shown, when the abnormal device N does not output the first result, the first communication devices c1, c2, c3 and W connected to the abnormal device N are set as the first connection devices, and the second time interval is set to 1 second. The second detection file refers to the physical layer judgment file. The abnormal device N sends the second detection file to the first connection devices c1, c2, c3 and W every 1 second. After receiving the second detection file, the first connection devices c1, c2, c3 and W will output the second result. By counting the number of second results, the status problem of the abnormal device N is determined. For example, the first connection devices c1, c2, c3 and W 3 and W both output the second result, then it is determined that the connection status of the communication route between the abnormal device N and each of the first connection devices c1, c2, c3 and W is normal, otherwise, the status problem of the abnormal device N is determined by calculating the first ratio a through the first formula. For example, there is one first connection device c1 that does not output the second result, and there are three first connection devices c2, c3 and W that output the second result. The numbers of the two first connection devices are substituted into the first formula, and the first ratio a is calculated to be 3 / 1=3, which is greater than 1, then the status problem of the abnormal device N is set to a device failure problem of the abnormal device.

[0054] In step S3, the uplink transmission device and the conversion device of the abnormal device are obtained based on the following steps:

[0055] The first communication device that sends power data to the abnormal device in the connection structure diagram is set as an uplink transmission device, and other first communication devices connected to the uplink transmission device except the abnormal device are set as conversion devices.

[0056] Specifically, there is a preset transmission direction in the network communication transmission process, so that the data information to be transmitted is transmitted in sequence according to the device connection order. In this embodiment, the uplink transmission device refers to the upper-level transmission device of the network communication transmission, and the conversion device refers to a device that can continue to transmit the power data of the uplink transmission device, for example Figure 2 In the example, the uplink transmission devices of the abnormal device N are the first communication devices c1, c2 and c3, wherein the first communication devices r1 and r2 connected to the uplink transmission device c1 are set as conversion devices.

[0057] In step S3, the uplink transmission device combines the power data and then extracts the best conversion device combination from the conversion devices based on the split combination method for split transmission, including the following steps:

[0058] The number of conversion devices is obtained and defined as a first number. If the first number is equal to 1, the abnormal device is replaced with the conversion device in the connection structure diagram to transmit the power data. If the first number is greater than 1, a conversion device combination is generated based on the first number of conversion devices, a power data set transmitted by the uplink transmission device to each conversion device and the abnormal device is obtained, each subset data in the power data set is combined according to the first number of conversion devices to generate a power data combination, and the load data of each uplink transmission device and the conversion device within a preset time is obtained respectively. The power data combination of the uplink transmission device and the conversion device combination are combined in a shunt combination mode to transmit the power data of the uplink transmission device, and the performance change value y corresponding to the shunt combination mode is calculated based on the second formula, so that the performance change value of the conversion device combination is minimized;

[0059] The second formula is , where n is the number of conversion devices in the combination, is the load data of the kth conversion device, is the power data of the tth power data combination, is the working performance function of the kth conversion device, and the power data combination is split and transmitted to the conversion device combination based on the second formula.

[0060] Specifically, in this embodiment, when the abnormal device has the first type of problem, when the uplink transmission device has only one conversion device, the power data to be transmitted from the uplink transmission device to the abnormal device is directly transmitted through the conversion device. When the number of conversion devices in the uplink transmission device is greater than 1, the power data can be transmitted by extracting the conversion device. Figure 2As shown, the uplink transmission device c1 of the abnormal device N has two conversion devices r1 and r2. The power data refers to the data information transmitted by the uplink transmission devices c1, c2 and c3 to each conversion device r1 and r2. The power data set refers to the set of power data to be transmitted by a certain uplink transmission device to each connected device. For example, the power data of the uplink transmission device c1 includes the power data e1 transmitted to the conversion device r1, the power data e2 transmitted to the conversion device r2 and the power data e3 transmitted to the abnormal device N. Then the power data set of the uplink transmission device c1 is (e1, e2, e3), and its corresponding conversion device combinations are (r1, r2), (r1) and (r2). ) three conversion device combinations, then, the number of each subset in the power data combination generated by the power data set must be less than or equal to the first number 2 of the conversion devices, for example, the power data combinations of each subset in the power data set (e1, e2, e3) of the uplink transmission device c1 are (e1+e2+e3, 0), (e1+e2, e3), (e1+e3, e2), (e2+e3, e1), the split combination method refers to the corresponding combination of each subset in the power data combination and the conversion device combination in each subset, the load data refers to the capacity of the data information in each first communication device, and the load data of each first communication device is a value that fluctuates over time, for example, Figure 4 The first curve L1 is a curve of the load data of the uplink transmission device c1 with respect to the preset time. The performance change value refers to the performance change size of each conversion device. The smaller the performance change value, the more stable the transmission performance of each selected conversion device and the best working performance. When the abnormal device N fails, the load state of the uplink transmission device c1 is not updated in time. Therefore, it is necessary to select a conversion device combination through a shunt combination method to perform shunt transmission of power data, and the performance change value of each conversion device in the conversion device combination is minimized through the shunt combination method.

[0061] In the second formula, the work performance function It is set according to the factory specifications of each first communication device, and the working performance function It refers to the relationship function between the load data and the working performance of the first communication device, for example Figure 5 In the figure, curve L2 is the working performance of the conversion device r1 With load data The working performance function curve of the change, the conversion device combinations of the uplink transmission device c1 are (r1), (r2) and (r1, r2), the power data combinations of the uplink transmission device c1 are (e1+e2+e3), (e1+e2, e3), (e1+e3, e2), (e2+e3, e1), the split combination method is to transmit the subsets of the conversion device combination and the power data combination correspondingly, and compare the size of the performance change value y through the second formula. For example, there are 4×3=12 transmission methods for selecting the uplink transmission device c1, among which, if method 1 is to transmit the (e1+e3) subset of the power data combination (e1+e3, e2) to the conversion device The conversion device r1 in the power data combination (r1, r2) is selected, and the e2 subset is transmitted to the conversion device r2. Substituting it into the second formula, the performance change value corresponding to mode 1 is calculated to be 5. If mode 2 is to transmit the (e1+e3) subset in the power data combination (e1+e3, e2) to the conversion device r2 in the conversion device combination (r1, r2), and the e2 subset is transmitted to the conversion device r1, the performance change value corresponding to mode 2 is calculated to be 8. In this way, the performance change values ​​corresponding to each shunt combination mode are calculated, and the sizes of each performance change value are compared. Finally, the shunt combination mode with the smallest performance change value is selected to transmit the power data in the uplink transmission device c1. Through the shunt combination mode, the power data combination and conversion device combination with the best transmission effect can be determined in real time, which ensures the reliability of power data and improves the stability of each first communication device in the power system communication network.

[0062] In step S4, an alternative route is obtained based on the following steps:

[0063] Obtain the location information of the abnormal device and the number of communication routes from the network structure diagram, obtain the network transmission distance and network transmission rate of each communication route based on the location information and the communication route, set a first comparison value, compare the network transmission distance and network transmission rate of each communication route based on the first comparison value, extract the communication route with the largest first comparison value and set it as a backup route, and calculate the first comparison value using the third formula , the third formula is: ,in, is the first comparison value of the jth communication route, is the network transmission distance of the jth communication route, is the network transmission rate of the jth communication route.

[0064] Specifically, in this embodiment, if Figure 3As shown, when the status problem of the abnormal device is the second type of problem, the communication routes between the various first communication devices can be clearly obtained through the network structure diagram. The communication routes include network transmission distance and network transmission rate. For example, the communication connection mode of each first communication device in communication route 1 is "device P, device c2, device N and device W". When the communication route L3 between the uplink transmission device c2 and the abnormal device N is interrupted, the communication route of the first communication device c2 having the same starting point as the communication route L3 and the first communication device W having the same transmission terminal as the first communication device c2 is obtained in the network structure diagram, and the communication routes that meet the conditions are compared. The first comparison value of each communication route is calculated by the third formula, and the communication route with the smallest first comparison value is selected and set as the backup route. For example, the first comparison value calculated for communication route 2 "device P, device c2, device c1, device N and device W" is 7, and the first comparison value calculated for communication route 3 "device P, device c2, device c1, device r1 and device W" is 6, then communication route 3 is set as the backup route, and communication route 1 is changed to the backup route for data information transmission.

[0065] If there is no first communication device other than the abnormal device connected to the uplink transmission device, a first text information library is set up, the first text information library includes problem types and solutions, the alarm information of the abnormal device is obtained, the first keyword of the alarm information is extracted, and the problem type is mapped based on the first keyword to obtain a solution to solve the first type of problem and send it to the preset first monitoring device.

[0066] Specifically, Figure 6 As shown, in the connection structure diagram of the abnormal device N1, when the first communication devices are linearly connected, the uplink transmission device c21 of the abnormal device N1 is not connected to other first communication devices, and it is necessary to manually process the fault problem of the abnormal device N1. In order to quickly obtain a solution, a large amount of equipment failure history information can be collected to establish a first text information library, which contains various problem types and corresponding solutions.

By comparing the first text information library, the corresponding solution is generated as "clear memory", and the solution "clear memory" is sent to the first monitoring device.
