Description
Technical field
It prevents and reduces natural disasters technical field the invention belongs to power grid, is related to a kind of supervising based on the mountain fire of infrared guidance and radar detection
Examining system and method.
Background technique
With the continuous construction and development of power grid, demand of the society to power supply reliability is higher and higher.Transmission line of electricity is electricity
One of important component of net, operating status decide the stabilization and safety of entire power grid, and power transmission line caused by mountain fire
Road failure seriously affects always the safe and stable operation of transmission line of electricity.This is mainly due to transmission line insulator caused by mountain fire is strong
Degree decline, caused by causing air breakdown.The harm how effectively to prevent and reduce mountain fire to passway for transmitting electricity reduces power grid
Failure and power outage, it is that electric power enterprise is urgent that raising power grid operation level, which is more secure and reliable national economy service,
Problem to be solved.Mountain fire is monitored, taking timely measure and carrying out control to the transmission line of electricity in mountain fire region is to reduce
Important means of the mountain fire to the threat of transmission line of electricity.The current disaster monitoring means of transmission line of electricity mainly have manual inspection and use
On-Line Monitor Device cannot still fully meet the requirement of the round-the-clock monitoring of route disaster and early warning.Manual inspection cannot achieve prison
Real-time is surveyed, and various traditional on-Line Monitor Devices have that monitoring range is limited, monitoring data information content is few, it can not
Meet to meteorological disaster, mountain fire, external force destruction is effectively monitored and the requirement of early warning.
Currently, transmission line forest fire monitoring method mainly has video image monitoring, infrared sensing monitoring, satellite remote sensing prison
It surveys.There is easily wrong report and fail to report, monitor regional scope and limited by video equipment performance, cannot achieve mountain fire position in video image monitoring
The defects of positioning set.Infrared sensing monitoring method can realize unattended uninterrupted monitoring, automatic to find in monitoring area
Fiery point, while can also check live realtime graphic, be put out a fire according to the direct command scheduling of intuitive picture.But infrared monitoring can be right
Sunlight, high temp objects etc. generate false-alarm, cannot achieve the accurate positioning to fire source, and misty rain day is to observed range and image clearly
Degree is affected.Satellite Remote Sensing mountain fire is also a kind of common means, and this method can carry out the monitoring of wide area to mountain fire, but
This method has that false alarm rate is high, and is limited by satellite transit time, it is difficult to realize round-the-clock monitoring, additionally there are
Monitoring result monitors the problems such as resolution ratio is not high vulnerable to sky cloud effect.
Radar monitoring technology is in the field of preventing and reducing natural disasters using long-standing.Radar remote, scan area with detection range
Greatly, scanning is limited small advantage, it can be achieved that a wide range of, round-the-clock, quick, dynamic ring rapidly, by visibility and steric requirements
Border and disaster monitoring, and have the characteristics that acquisition of information rapidly and accurately, stable and reliable operation, disaster monitoring, the condition of a disaster assessment, fortune
Animal body monitoring etc. shows huge potentiality.Infrared detection technique has good recognition capability to mountain fire, still
Infrared detector, which usually cannot achieve, measures the distance of ignition point, cannot achieve the accurate positionin to mountain fire.Therefore it ties
The defect of traditional infrared mountain fire monitoring device can effectively be made up by closing millimetre-wave radar and infrared electronic technology, and it is complete to reach round-the-clock
The use purpose of weather realizes the accurate positionin to mountain fire fire point.Realize automatic discovery, automatic positioning, automatic alarm, reduce by
The line tripping accident rate caused by mountain fire promotes the ability that transmission line of electricity resists mountain fire disaster.

The media such as rain, mist, cigarette are penetrated, and are weakened with the increase of medium.Mountain fire regional background temperature is generally at -40~60 DEG C, mountain
Flame temperature is up to several hundred or even thousands of degrees Celsius when fire occurs, and the two temperature difference is larger, and being easy in thermal image can
The combustion case of combustion things is separated from terrain backgrounds, to achieve the purpose that mountain fire detects.
Millimeter wave is the electromagnetic wave between microwave and light wave, and frequency range is 30~300GHz, and wavelength is 1~10mm.
Millimetre-wave radar can obtain under miniature antenna aperture higher antenna gain, and has the advantages that high resolution, can be applicable to
Structure is small, light-weight, high and with good doppler processing characteristic the occasion of resolving power.Compared with microwave, millimeter wave resolving power
Height, structure are light and small；With infrared and visible light ratio, millimetre-wave radar can direct measuring speed and distance.Due to most of occasions
Under, the smoke detection of mountain fire will be earlier than flame detecting, therefore it is to early stage that application millimeter wave, which carries out the smoke detection of mountain fire,
Effective detection mode of mountain fire can be reduced largely because of mountain fire sustained combustion and bring loss, be utilized simultaneously
The characteristic of millimetre-wave radar precision ranging realizes the accurate positionin to fire point.

Data processing host combines the distance of measurement and the ignition point orientation of determination, determines the position coordinates of ignition point, determines
The position of ignition point；
The geographical environment information of S3, millimetre-wave radar detection device during detecting smog, near detection acquisition ignition point
With vegetative coverage information, data processing host assesses current wind speed according to the moving direction and speed of detection smog,
In conjunction with the specific location of transmission line of electricity, mountain fire is analyzed to the danger classes of transmission line of electricity, carries out division of fire size class, is implemented pre-
Alert work.
8. a kind of mountain fire monitoring method based on infrared guidance and radar detection according to claim 6 or 7, feature exist
In data processing host carries out infrared image sensing analysis, including the following contents in the A3：
1) after obtaining infrared image, the median filtering technology for first passing through Local Operator denoises mountain fire infrared picture data
Processing, then the current infrared image that will acquire carry out difference with previous image, judge whether there is abnormal generation；If there is different
Often it is judged as the image for having fire suspicious region, otherwise, continues waiting for obtaining next image；
2) image space is divided into several regions according to feature, the picture characteristics in the same area is identical, in different zones
Picture characteristics is different；
3) feature extraction and pattern-recognition of infrared image are carried out using the method for Digital Image Processing.
9. a kind of mountain fire monitoring method based on infrared guidance and radar detection according to claim 8, it is characterised in that：
The feature is flame region feature；
Flame region feature includes geometrical characteristic, textural characteristics, grey level histogram feature and flame dynamic features；Wherein, geometry
Feature includes conflagration area area, circularity, boundary perimeter and edge roughness；Textural characteristics include energy, entropy, the moment of inertia,
Related and local stationary mean value；Grey level histogram feature is the mean value of brightness and the probability of standard deviation and gray value
Feature；Flame dynamic features are extracted by continuous two picture, including area of flame change rate and mass center displacement.
