Description

Technical Field

[0001] The present invention relates to the technical field of power system safety protection, and in particular to a method, device and medium for monitoring the flammability of vegetation around a power transmission channel. Background Art

[0002] With the continuous development and progress of society, power transmission has become an indispensable part of people's lives. Transmission channels are an important part of transmission lines, mainly referring to vegetation areas such as woodlands, grasslands or bushes on both sides of the transmission lines. Since the transmission channels are long and narrow, and the vegetation is dense, once a fire occurs, it is easy for the fire to spread rapidly due to the open location and rich vegetation, causing serious impacts on the transmission lines.

[0003] At present, the existing technologies mainly have the following ways to monitor the flammability of vegetation around power transmission channels: 1. Manual inspection. Through manual on-site inspection, the problem can be directly found, but it takes a lot of manpower and time, especially for long-distance and large-scale power transmission channels, it is difficult to achieve comprehensive and timely monitoring; 2. Satellite remote sensing monitoring. It covers a large area and can quickly obtain data, but it has limited spatial resolution and cannot identify the flammability characteristics of small-scale and detailed vegetation around the power transmission channel, and it is easily affected by weather; 3. Sensor monitoring. It uses sensors to directly collect data with high real-time performance. However, because the coverage area of ​​the power transmission channel is large, a large number of sensors are required for collection, which will greatly increase the analysis and processing burden of the system, and the sensors can only monitor the relevant parameters of the environment and vegetation, and cannot directly observe the fire source or fire situation. Summary of the invention

[0004] The technical problem to be solved by the present invention is that due to the complexity of the monitoring target, the monitoring is not timely and the monitoring accuracy is low. The purpose is to provide a method, equipment and medium for monitoring the flammability of vegetation around the transmission channel. Through an independent vegetation monitoring system, vegetation data and meteorological data are collected in all directions, and comprehensive analysis is performed to obtain the flammability index level of vegetation around the transmission channel. The independent vegetation monitoring system can realize independent processing of a single area block, effectively reducing the operating processing pressure on the main control system; the monitoring system will first divide the area around the transmission tower into monitoring area blocks, and install an independent vegetation monitoring system on the transmission tower. The system can collect multiple parameters, such as vegetation type, coverage area, temperature, etc. The system will collect data on the vegetation’s temperature, moisture content and growth height, and combine these data with meteorological data to calculate the vegetation’s flammability index through a specific algorithm. The monitoring system will also determine this index based on the flammability risk level. When there is no flammability risk or a low flammability risk, the system will not transmit data to the external main control monitoring system. When there is a medium or high flammability risk, the system will immediately upload data and take corresponding early warning measures based on the specific circumstances of the transmission channel area block. In particular, when encountering special circumstances such as lightning strikes, line fault discharges, man-made fire sources or wildfires, the system will directly determine it as a high flammability risk and immediately alarm the main control system so that fire extinguishing and protective measures can be taken quickly to ensure the safe operation of the transmission channel.

[0005] The present invention is achieved through the following technical solutions:

[0051] The storage module can realize the storage of vegetation data packets within a single transmission channel area block, meteorological data packets and program data within a single transmission channel area block;

[0052] An independent power supply module is used to realize independent power supply operation of an independent vegetation monitoring system.

[0053] S2: Perform multi-source data collection operations on vegetation within the transmission channel area block through an independent vegetation monitoring system to form a vegetation data packet within a single transmission channel area block;

[0054] S3: connecting the independent vegetation monitoring system to the meteorological system, and inputting the meteorological data of the transmission channel area block into the monitoring system to form a meteorological data packet of a single transmission channel area block;

[0055] S4: Perform comprehensive analysis based on the vegetation data package within the single transmission channel area block and the meteorological data package of the single transmission channel area block to form the vegetation flammability index within the area block;

[0056] Specifically, a comprehensive analysis is performed based on the vegetation data packet within the single transmission channel area block and the meteorological data packet of the single transmission channel area block, including the following steps:

[0057] S41: extracting vegetation data inside the power transmission channel area block in the vegetation data packet, and assigning points according to each extracted vegetation data parameter value to obtain a scoring value based on the vegetation data;

[0058] S42: extracting data from the meteorological data packet, assigning weights based on the extracted meteorological data, and correlating the vegetation data with the meteorological data to obtain a single index value of the vegetation data based on the meteorological weight;

[0059] S43: Based on exponential addition of relevant parameters that are beneficial to combustion, and based on exponential subtraction of relevant parameters that are not conducive to combustion, the flammability index value of vegetation around the transmission channel is obtained;

[0060] Furthermore, the correlation between meteorological data and vegetation data includes the correlation between air temperature and vegetation temperature, wind speed and vegetation coverage area, wind speed and vegetation distribution density, wind speed and vegetation growth height, precipitation and vegetation water content, and humidity and vegetation type;

[0061] S44: Output the obtained flammability index value of vegetation around the power transmission channel, and determine the flammability level of vegetation around the power transmission channel based on the standard.

[0062] Specifically, the calculation formula of the flammability index is: Flammability Index = Temperature Weight × Vegetation Temperature + Wind Speed ​​Weight × (Vegetation Coverage Area + Vegetation Distribution Density + Vegetation Growth Height) - Precipitation Weight × Vegetation Water Content - Humidity Weight × Vegetation Type. The above temperature weight, wind speed weight, precipitation weight and humidity weight will be determined based on the meteorological environment around the transmission channel.

[0067] Medium flammability risk: the vegetation around the transmission channel is flammable or is prone to combustion under the monitored meteorological conditions. The probability of flammability of the vegetation is 25%-65%;

[0068] High flammability risk. Vegetation around the transmission channel is very prone to spontaneous combustion and the risk of vegetation burning is further increased under the detection of meteorological kits. The probability of vegetation flammability exceeds 65%.

[0069] Furthermore, when the flammability level is no flammable risk and low flammable risk, the independent vegetation monitoring system does not upload data to the external main control monitoring system. When the flammability level is medium flammable risk and high flammable risk, the independent vegetation monitoring system uploads data to the external main control monitoring system and performs positioning and alarm based on the transmission channel area block. Through the above operations, the data can be processed on-site in the area block without the need for complicated uploading and centralized processing steps, effectively reducing the operating pressure of the main control system on the entire monitoring system, and because only the upload operations of medium flammable risk and high flammable risk are performed, the main control's monitoring of the surrounding area of ​​the transmission channel is more convenient.

[0070] Furthermore, the independent vegetation monitoring system will directly determine the flammability risk level of the transmission channel area block as high flammability risk for special flammable conditions inside the transmission channel area block, including one or more of lightning strikes, line fault discharges, fire sources caused by human activities, and wildfires, and upload it to the external main control monitoring system so that fire extinguishing and protection measures can be taken quickly to ensure the safe operation of the transmission channel.
