In this embodiment, the method includes the steps of:
step 201, acquiring a device identifier of a front-end monitoring device corresponding to the power transmission line to be monitored.

The front-end monitoring equipment further comprises a corresponding equipment identifier, and the equipment identifier is specifically used for determining the position information of the front-end monitoring equipment and the data type of the data acquired by the front-end monitoring equipment.
Specifically, the power transmission line state monitoring method is used for monitoring the state of the power transmission line in the designated area. In the past, the inspection of the power transmission line mainly depends on the periodic inspection of operation and maintenance personnel, although the potential equipment hazards can be found, the detection of special environment and climate is lacked due to the limitation of the inspection, the external force change of a line corridor cannot be timely mastered in the vacuum period of the inspection period, and the line accidents are very easy to occur due to the lack of monitoring before the next inspection. According to the method and the device, the state monitoring of the power transmission line to be monitored is achieved through the front-end monitoring device corresponding to the power transmission line to be monitored, the sensing information corresponding to the power transmission line to be monitored, namely the power transmission line state monitoring data, is collected through the front-end monitoring device, and then the power transmission line state monitoring data are processed through the subsequent internet of things gateway server and the external monitoring platform, so that the state of the power transmission line is effectively determined. When monitoring the state of the power transmission line, the device identifier of the front-end monitoring device needs to be acquired first, so that the position of the front-end monitoring device and the type of the acquired sensing information are determined. In one embodiment, the front-end monitoring devices correspond to 5G terminals, and may be connected to the respective corresponding 5G wireless terminals, and a virtual server is set in the 5G wireless terminals, so that the virtual server sends its specific device identifier to the internet of things gateway server 102. And the internet of things gateway server 102 and the front end monitoring device 104 communicate through a 5G communication network.
And 203, performing resource quantity initialization processing on the initial network slice corresponding to the front-end monitoring device according to the device identifier, and acquiring an exclusive network slice corresponding to the front-end monitoring device.
The network slice is a networking-on-demand mode, an operator can separate a plurality of virtual end-to-end networks on a unified infrastructure, and each network slice is logically isolated from a wireless access network bearing network to a core network so as to adapt to various types of applications. In one network slice, at least three parts of a wireless network sub-slice, a bearer network sub-slice and a core network sub-slice can be divided.

In the present application, the internet of things gateway server 102 and the front-end monitoring device 104 communicate with each other through a dedicated network slice. In one embodiment, the procedures for authentication between the internet of things gateway server 102 and the front-end monitoring device 104 are also included, and when the authentication is completed, the front-end monitoring device 104 can access the respective dedicated network slice to perform communication.
Specifically, after the device identifier of the front-end monitoring device is obtained, in order to reduce the transmission delay on the network slices of the front-end monitoring device and the internet of things gateway, the internet of things gateway server 102 initializes the resource amount owned by each network slice in advance for different front-end monitoring devices, so as to perform preprocessing of transmission line state monitoring data transmission. Different resources are allocated to the network slices corresponding to different front-end monitoring devices, so that the efficiency of data transmission is ensured. For example, more resources are occupied by video data transmission slices, and fewer resources are needed by text data transmission slices; or, for the front-end monitoring equipment arranged in the important area, marking the front-end monitoring equipment and preferentially allocating more bandwidth resources to the front-end monitoring equipment. By optimizing the bandwidth of the exclusive network slice and reasonably adjusting the occupied resources of the network slice, the time delay of data transmission can be effectively reduced, and the network pressure can be relieved.
And step 205, acquiring the power transmission line state monitoring data uploaded by the front-end monitoring device through the dedicated network slice corresponding to the front-end monitoring device.
And step 207, acquiring a monitoring result corresponding to the power transmission line to be monitored according to the power transmission line state monitoring data.
The power transmission line state monitoring data refers to sensing data acquired through front-end monitoring equipment.
Specifically, after the corresponding exclusive network slice is set for the front-end monitoring device, the power transmission line state monitoring data uploaded from the front-end monitoring device can be efficiently acquired through the exclusive network slice. And the Internet of things gateway server can send the power transmission line state monitoring data to the corresponding external monitoring platform after receiving the power transmission line state monitoring data, and further performs data processing on the power transmission line state monitoring data through the external monitoring platform to obtain a corresponding monitoring result. And the external monitoring platform receives the state monitoring data of the power transmission line in real time, so that the state monitoring including the inclination prediction of the power tower, the on-line monitoring of insulator contamination/leakage current, the vibration monitoring of a wire of the power transmission line, the monitoring of equivalent icing thickness of the power transmission line, the state monitoring of equipment, the safety monitoring of the operation of a power transmission and transformation field and the like is realized, and the intelligent monitoring of the whole process of the known, credible and visual power production is realized.

According to the method and the device, the corresponding resource amount is distributed to the initial network slice corresponding to the front-end monitoring device by obtaining the device identification of the front-end monitoring device corresponding to the power transmission line to be monitored, the exclusive network slice is obtained, the power transmission line state monitoring data uploaded by the front-end monitoring device is obtained through the exclusive network slice, and therefore the monitoring result corresponding to the power transmission line to be monitored is further obtained. By optimizing the resource amount of the exclusive network slice and reasonably adjusting the occupied resources of the network slice, the time delay of data transmission can be effectively reduced, timely data transmission is realized, and the state of the power transmission line is monitored in real time.

Step 306, determining the network resource amount corresponding to the initial network slice according to the link flow, the node calculated amount and the node cache amount, and acquiring the exclusive network slice corresponding to the front-end monitoring device.
The transmission data type corresponding to the front-end monitoring device refers to a data type of data acquired by the front-end monitoring device, and images or videos, for example, are all data types. The transmission data resource amount corresponding to the front-end monitoring device refers to the data amount of the data acquired by the front-end monitoring device.
Specifically, in order to reduce the transmission delay on the dedicated network slice of the front-end monitoring device and the internet of things gateway, the network resource manager in the base station may initialize the resource amount owned by each network slice in advance by aiming at the front-end monitoring devices of each data type (such as a device for transmitting video data, a device for transmitting image data, and a device for transmitting text parameters); determining the transmission data requirement of the equipment and the required resources thereof according to the equipment identification of the front-end monitoring equipment accessed to the slice, and calculating the link flow, the node calculated amount, the node buffer amount and the like of each slice; and dynamically allocating the network resource amount among the plurality of network slices according to the calculated data. For example, more resources are occupied by video data transmission slices, and fewer resources are needed by text data transmission slices; or, for the front-end monitoring equipment arranged in the important area, marking the front-end monitoring equipment and preferentially allocating more bandwidth resources to the front-end monitoring equipment. In the embodiment, by optimizing the bandwidth of the exclusive network slice and reasonably adjusting the occupied resources of the network slice, the time delay of data transmission can be effectively reduced, and the network pressure can be relieved.

The equipment identifier further comprises position information corresponding to the front-end monitoring equipment, and then weather information corresponding to the front-end monitoring equipment can be determined through the equipment position information. And a database in the gateway server of the internet of things prestores normal weather information, abnormal weather information and equipment monitoring information of front-end monitoring equipment under various abnormal weather conditions. The monitoring grade corresponding to the front-end monitoring equipment can be determined by comparing the abnormal weather information stored in the database with the weather information corresponding to the front-end monitoring equipment. And the monitoring grade is used for representing the importance degree of the power transmission line state monitoring data acquired by the front-end monitoring equipment. Generally speaking, in a severe weather environment, the more likely the power transmission line is to be abnormal, and therefore, a more preferred monitoring level is assigned to the front-end monitoring device in the severe weather environment to ensure the preferential transmission of data.
Specifically, the gateway server for internet of things specifically comprises a database. For special scenes (such as severe weather of continuous overcast and rainy days, low temperature and the like), normal weather information and abnormal weather information, and equipment monitoring information of the front-end monitoring equipment under various abnormal weather conditions are stored in the database. For example, in a specific embodiment, according to data in the database, it may be identified that a certain area is snowstorm weather by weather information corresponding to the front-end monitoring device, and the device monitoring information marks a sensor for monitoring the icing condition of the power transmission line as a first-level monitoring device, marks a sensor for monitoring the condition of the power tower as a second-level monitoring device, and marks the rest as third-level monitoring devices, where the importance degree is the first-level and the highest, so as to allocate network bandwidth according to the importance degree, so that the important monitoring device preferentially transmits data of the device. At this time, the network resource manager allocates the slice resources according to the transmission data requirements of the equipment, and calculates the link flow, the node calculation amount, the node buffer amount and the like of each slice; the amount of network resources among the plurality of network slices is reallocated based on the data calculated above. And further, under the abnormal condition, the edge computing equipment performs screening analysis on the monitoring data and preferentially transmits the data of the equipment to the cloud platform. Specifically, the main improvement of the present embodiment lies in a resource allocation method for a transmission line data transmission network in a special scene, which specifically includes: when the current weather is identified to be normal weather according to the database, the data transmission requirement (that is, whether more resources need to be occupied, such as video data transmission equipment) identified by the front-end monitoring equipment and the required resources are acquired, and the first priority parameter of the equipment is identified. And the front end monitors the importance degree of the area where the equipment is located, and marks a second priority parameter. It should be noted that, the second priority parameter of the front-end monitoring device is initialized, the priority of the front-end monitoring device set in the area is identified in advance according to the important area stored in the database, and each front-end monitoring device is identified according to the initialized second priority under the normal weather condition. Then, the second priority of the method changes under different environmental conditions (such as weather), for example, the area where the current snowstorm weather occurs is marked as an important area, all front-end monitoring devices arranged in the area are marked with the second priority parameters, so that the real-time monitoring data of the front-end monitoring devices in the area where the special weather occurs are preferentially acquired, and the priority of the front-end monitoring devices in other non-important areas is correspondingly reduced. Thus, in normal weather conditions, the priority of the resource allocation of the front-end monitoring device data transmission network is the sum of the first priority parameter and a second priority parameter, wherein the second priority parameter is greater than the first priority parameter. By dynamically adjusting the priority of the equipment, the bandwidth resources required by the service are adjusted in time in combination with the current service requirement, and more transmission bandwidths are configured for the slices with higher priorities. In addition, when the current weather is identified to be abnormal weather according to the database, the front-end monitoring equipment set in the area where the abnormal weather occurs is obtained, the grade of the corresponding monitoring equipment is marked according to the equipment monitoring information of the database, and the third priority parameter of the corresponding monitoring equipment is marked. Therefore, under the condition of abnormal weather, the priority of resource allocation of the data transmission network of the front-end monitoring equipment is the sum of the first priority parameter, the second priority parameter and the third priority parameter, so that the network bandwidth is allocated according to the importance degree of the monitoring equipment, and the important monitoring equipment preferentially transmits the data of the equipment. In this embodiment, the monitoring level corresponding to the front-end monitoring device is determined through the weather information, so that effective transmission of power transmission line state monitoring data under extreme weather conditions can be effectively ensured, the time delay of data transmission can be effectively reduced, and the network pressure can be relieved.

Step 207 comprises: and transmitting the power transmission line state monitoring data to an external monitoring platform through the platform network slice, and acquiring a monitoring result corresponding to the power transmission line to be monitored, which is fed back by the external monitoring platform according to the power transmission line state monitoring data.

In another embodiment, the verification platform may also verify a process of accessing the front-end monitoring device to the internet of things gateway server, and the internet of things gateway server further includes a security monitoring platform, after the front-end monitoring device accesses the dedicated network slice, the verification platform may send a monitoring signal to the security monitoring platform, and send corresponding security channel parameters to the accessed front-end monitoring device and the internet of things gateway server, and the front-end monitoring device and the internet of things gateway server establish a security channel through the security channel parameters to perform communication. In another embodiment, an emergency channel may also be set, when the current-end monitoring device determines that the weather is abnormal, an emergency request is generated when the emergency degree is high, and the emergency request is sent to the gateway server of the internet of things, and the gateway server of the internet of things responds to the request, and allocates the emergency channel after the device identity is quickly verified. In the embodiment, the external monitoring platform after the identity authentication is accessed to process the power transmission line state monitoring data, so that the accuracy of monitoring result identification can be effectively ensured.

Specifically, the gateway server of the internet of things further comprises a safety monitoring platform, the safety monitoring platform monitors an external monitoring platform in the network slice, and if an unsafe platform is found, the corresponding platform network slice is moved out. In one embodiment, in the application, the security of the external monitoring platform can be determined by comparing whether keywords, information expressions and the like in the operating data of the platform are tampered and according to the identification result. And if the safety value of the platform exceeds a preset threshold value, judging that the platform is unsafe, and moving the platform network platform out of the slice.
