Problems solved by technology

However, although the above scheme starts the on-site camera after confirming the suspected mountain fire situation information, which reduces the data transmission volume and stability, it still needs to arrange more cameras on the site, and in order to ensure the camera’s shooting range and avoid the occlusion of trees, The camera needs to be installed on the top of the transmission line tower, or other positions that are at least higher than the surrounding trees, and there are problems such as high failure rate in the later stage and difficult maintenance

Embodiment 1

[0054] like figure 1 As shown, this embodiment discloses a method for monitoring, early warning and positioning of mountain fires on transmission lines, including the following steps:

[0055] S1. According to the remote sensing data of the geostationary orbit satellite, it is judged whether there is a fire possibility, if so, the fire scene is located by the remote sensing image target positioning algorithm and step S2 is executed;

[0056] The remote sensing image target location algorithm can be carried out through the following steps: wavelet decomposition, feature detection and feature description, feature matching, similarity judgment and target location. Of course, when it is put into use, remote sensing image target positioning algorithms of other technologies can also be used to locate the fire scene.

[0057] S2. Drive at least one monitoring drone 3 to the fire scene; this embodiment preferably dispatches multiple monitoring drones each time, and multiple monitorin...

Embodiment 2

[0079] like image 3 As shown, this embodiment is similar to Embodiment 1, except that the system of this embodiment also includes a rain drone, and the method of this embodiment also includes step S5:

[0080] S5. Start the rain drone 4 when it is confirmed that there is a fire;

[0081] Here, the rain drone 4 can be started manually by the staff according to the situation at that time, or the rain drone 4 can be automatically started by the GIS monitoring platform 1 . The GIS monitoring platform 1 can start the rain drone 4 when it is confirmed that there is a fire, and can also obtain meteorological data when it is confirmed that there is a fire, and automatically start the rain drone 4 according to the weather conditions in the weather data, such as in cloudy conditions If the rain falls, the rain drone 4 can be started, and the rain drone will not be started on a sunny day.

[0082] Specifically, the rainfall UAV 4 has a temperature sensor and an artificial rainfall cat...

Embodiment 3

[0094] like Image 6 As shown, the present embodiment discloses a transmission line mountain fire monitoring and early warning and positioning system based on the above method, including a GIS monitoring platform 1, and the GIS monitoring platform 1 includes a mountain fire monitoring and positioning module and a command and dispatch module, The mountain fire monitoring and positioning module is connected to the geostationary orbit satellite system 2 and stores a remote sensing image target positioning algorithm;

[0095] The command and dispatch module is connected with the monitoring UAV 3 and the rainfall UAV 4, and the monitoring UAV 3 includes the first master of the UAV and the first master connected to the UAV. Camera, the first GPS module, the first wireless module and the first temperature sensor, described monitoring drone 3 is connected to the command and dispatch module of GIS monitoring platform 1 by described first wireless module; Described rainfall drone 4. It...

Abstract

The invention provides a power transmission line forest fire monitoring, early warning and positioning system and method, and the method comprises the following steps: S1, judging whether there is a fire possibility or not according to the remote sensing data of a synchronous orbit satellite, if yes, positioning a fire scene through a remote sensing image target positioning algorithm, and executing the step S2; S2, driving at least one monitoring unmanned aerial vehicle to go to the fire scene; s3, acquiring a shot picture returned by the monitoring unmanned aerial vehicle and displaying the shot picture on the GIS monitoring platform; and S4, determining the fire possibility according to the shot picture, and circling a fire area according to the shot picture when determining that the fire exists. The scheme is matched with the unmanned aerial vehicle, when a suspected fire occurs, the unmanned aerial vehicle is started to go for detection, dual confirmation can be achieved, the mountain fire disaster detection accuracy is guaranteed, meanwhile, a large number of cameras do not need to be installed, and the camera maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of transmission line mountain fire prevention, and in particular relates to a transmission line mountain fire monitoring, early warning and positioning system and a method thereof. Background technique [0002] A large number of transmission lines of my country's power grid are distributed in forests and other places prone to fire accidents, which pose a great threat to the safe operation of transmission lines. Therefore, it is necessary to monitor and warn wildfires so that staff can take active actions before wildfires threaten transmission lines. respond. [0003] The monitoring and early warning of wildfires first need to monitor whether there is a fire, and then locate the location of the fire, and then predict the threat of the fire to the transmission line based on the location of the fire and the location of the transmission line. For example, a Chinese patent discloses a method for monitoring and ea...
