Abstract
An infrared imaging monitoring system based on an uncooled infrared detector relates to the technical field of electrical fault monitoring. The infrared imaging monitoring system based on the uncooled infrared detector is characterized by comprising an uncooled focal plane display infrared detector, an image processor and a display. The image processor is used for processing a detection image generated by the uncooled focal plane display infrared detector to form an image which is clear and obvious and which is easy to observe a detection result. The display is used for displaying the image processed by the image processor. The image processor comprises a non-uniformity correction circuit, a digital image detail enhancer, an infrared image histogram sectional corrector, and an infrared image contrast booster which removes the ineffective gray scale. The infrared imaging monitoring system provided by the invention is reasonable in structure and based on the uncooled infrared detector, can penetrate dust, smog, sleet and darkness, provides a perfect image and a clear image.
Description
Technical field:
The present invention relates to electric fault monitoring technical field, be specifically related to a kind of infrared imaging monitoring system based on non-refrigerated infrared detector.
Background technology:
Ubiquity joint looseness or the loose contacts such as current electric device, transformer, connector, ballast resistor, cause occurring the appearance of uncompensated load, overload, the hidden danger such as overheated.Then often there is Bearing Temperature in motor, generator, short circuit in winding or open circuit, and carbon brush, slip ring and collector ring generate heat, the problems such as it is overheated to transship, cooling line blocking.And defective bearing can cause the damage of iron core or winding circle, defective carbon brush then can damage slip ring and collector ring, and then damages winding coil, also may cause the damage driving target.
In order to prevent the appearance of these problems, need effectively to monitor these equipment, make just can be quick, accurate, safe before device fails discovery fault.The monitoring equipment used at present is all the mode adopting signals collecting usually, thus is difficult to the place and the reason that obtain fault exactly.Also have some monitoring equipments to use the mode of image to monitor, but the formation method of existing monitoring equipment need to have good illumination condition, is often difficult to effective imaging, thus is unfavorable for monitoring in the environment such as dust, smog, sleet and dark.In addition, existing monitoring equipment cannot carry out treatment and analysis effectively to the image of monitoring, causes the inefficiency of failure judgement.
Therefore, at present can imaging in high quality under severe conditions in the urgent need to one, and the monitoring system of guilty culprit can be determined efficiently, in high quality.
Summary of the invention:
Technical matters to be solved by this invention be to overcome existing technological deficiency provide a kind of rational in infrastructure, based on the infrared imaging monitoring system of non-refrigerated infrared detector, it can penetrate dust, smog, sleet and dark, provides perfect image; And it can provide a kind of infrared imaging monitoring system based on non-refrigerated infrared detector of image clearly.
Technical matters to be solved by this invention adopts following technical scheme to realize:
Based on an infrared imaging monitoring system for non-refrigerated infrared detector, it is characterized in that: comprise non-refrigeration focal surface display infrared eye, image processor and display;
The detection image that described image processor is used for described non-refrigeration focal surface display infrared eye generates processes, form clear, remarkable, to be easy to observe result of detection image, described display is for showing the image after described image processor process;
Described image processor comprises the infrared image contrast booster that Nonuniformity Correction circuit, digital picture detail enhancer, infrared image histogram segmentation corrector and invalid gray scale are rejected;
Described Nonuniformity Correction circuit is used for carrying out Nonuniformity Correction to described detection image, makes the unevenness <0.05 of the whole picture of described detection image;
Described digital picture detail enhancer, for promoting the details of described detection image, is convenient to the details identifying described detection image;
Described infrared image histogram segmentation corrector is used for carrying out segmentation correction to described detection image, to ensure the authenticity of the detection image obtained;
The infrared image contrast booster that described invalid gray scale is rejected for rejecting the invalid gray scale of described detection image, thus strengthens the contrast of described detection image.
Beneficial effect of the present invention is: the infrared imaging monitoring system based on non-refrigerated infrared detector of the present invention before device fails, can find fault fast, accurately, safely.Timeliness coverage before an electric terminal breaks down also keeps in repair, and the production shut-down can saved or avoid therefore causing, production declining, energy loss, fire be the expensive that brings of bust even.Meanwhile, its clear picture, monitoring effect is good.
