In the electric equipment products accessible surface temperature rise device for fast detecting of the present utility model, described support component is a tripod.
Fine adjustment stage in the utility model pick-up unit can change by regulating bolt in the position of level and vertical direction, thermal infrared imager and optics camera are fixed on the fine adjustment stage, therefore by regulating the bolt of fine adjustment stage, make two systems of thermal infrared imager and optics camera on same surface level.
In the utility model pick-up unit optical camera system and infrared system are fixed on the fine adjustment stage, in real work, make two systems of thermal infrared imager and optics camera on same surface level by the bolt of regulating fine adjustment stage, thereby make that the angle of gathering is identical.The principle of work of the utility model pick-up unit is: infrared image and the optical imagery of gathering product to be measured, and realize the mutual superposition of Infrared Thermogram and optical imagery that camera collects by computer control, the spatial information of all " points " is superimposed in the video field that temperature " field " that thermal infrared imager is recorded and optics camera record, the information that can show " field " fast, can find out the concrete locus of wherein any " point " again intuitively, realize the temperature rise of fast detecting electric equipment products accessible surface.
The utility model proposes a kind of electric equipment products accessible surface temperature rise device for fast detecting, realize fast detecting the temperature rise of electric equipment products accessible surface.The utility model device utilizes infrared temperature measurement system to carry out the noncontact temperature detection, judges the locus of temperature spot in conjunction with visible light, and thermometric speed is fast, and is easy and simple to handle, has wide practical value.
The utility model electric equipment products accessible surface temperature rise device for fast detecting, comprise: infrared thermography, optics camera, realize infrared monitoring and optical monitoring respectively, and utilize computing machine that infrared thermal imagery and optical imagery are superposeed, thereby the temperature value that shows each locus point is intuitively realized fast detecting.
Infrared video, initial temperature data (.DLV form), Infrared Thermogram etc. can be gathered and store to thermal infrared imager; Optical camera system obtains the optical imagery of testee, Infrared Thermogram and optical imagery are superposeed by algorithm, and can both observability or displaying ratio be regulated by software control, detect according to different product situation and test condition.
After detecting end, initial temperature data and stacking diagram are handled, shown maximum temperature, minimum temperature or the medial temperature of electric equipment products accessible surface with image processing software.Need to prove, initial temperature data (.DLV) file logging the temperature data of thermal infrared imager each pixel of gathering, provide basic foundation for adopting algorithm more complicated, more closing to reality from now on.
Owing to will use two systems of infrared thermal imagery and optics shooting that same product to be measured is monitored and images acquired simultaneously, in order to realize the reasonable stack of image, in the utility model thermal infrared imager and optics camera are fixed on the same fore-and-aft distance, thereby the angle that guarantees the product image to be measured that both collect is identical.Simultaneously, adopted a fine adjustment stage in the utility model, fine adjustment stage is provided with the regulating device that can adjust the fine adjustment stage position on level and vertical direction.The form of regulating device can be bolt, mechanical arm or other automation equipments.By the adjustment to the fine adjustment stage position, the image angle that makes two instruments of infrared thermal imagery and optics shooting gather is identical, after the image that is collected is handled through the image overlay of computing machine, with the position and the temperature thereof of product that correct response is surveyed.
When experimentizing operation, optics camera and thermal infrared imager are fixed on the fine adjustment stage, make infrared thermal imagery and two systems of optics shooting on same surface level by the bolt of regulating fine adjustment stage, the angle of collection is identical, guarantees the consistance of image overlay.
The available thermometric pattern of thermal infrared imager has a thermometric, line thermometric and face thermometric, selects different thermometric patterns according to the concrete property of product to be measured.Thermal infrared imager point thermometric is the same with thermocouple temperature measurement, also is to be used to detect certain any temperature.During the temperature rise of thermopair electricity measurer, request of national standard is to make thermopair record maximum temperature as far as possible, yet needs a large amount of point of cloth in the process of implementing, and the experience that the position of layouting need be a lot, and human factor is bigger, has error.The temperature rise of thermal infrared imager electricity measurer can at first be carried out the scanning calorimeter imaging to test zone, thereby judges the temperature rise peak that this is regional; Afterwards, point for measuring temperature is moved to this position, just can record the maximum temperaturerise in zone to be measured; Institute's measured value is compared with the higher limit of national standard defined, can judge electrical equipment should the zone heating whether qualified.The judgement of this infrared point temp measuring method temperature rise peak has more science than thermopair thermometry, has reduced to select the inaccurate error of bringing because of temperature measurement location.After using the infrared measurement of temperature method to find electrical equipment surface temperature rise peak, can also re-use the temperature rise that traditional thermocouple method is measured this point, this has just alleviated the work of layouting, and has saved manpower.The line thermometric can disposablely be measured the temperature of each point on the line.The zone thermometric is meant measures certain selected regional temperature, can survey this regional maximum temperature, minimum temperature or medial temperature.
According to the principle and the influence factor of thermal infrared imager, when carrying out infrared measurement of temperature, should note the influence of factors such as product material to be measured, surrounding environment, select suitable testing conditions, could guarantee test result precision height, and genuine and believable.The thermometric calibration factors comprise following some:
Focal length: the principle of thermal infrared imager thermometric is a thermal imaging, therefore whether whether focal length adjusted for measurement result correctly most important, more importantly be, after the infrared image storage, can application software be adjusted by image curve, but but can't change focal length, also can't eliminate other mixed and disorderly heat reflections, therefore when beginning to test in image storage back, at first will adjust the focal length of thermal imaging system, the image that makes thermal imaging system record is the most clear.If product to be measured top or on every side overheated the or cold excessively reflections affect of background measure to product to be measured accuracy the time, try to adjust focal length or measure the orientation, to reduce or to eliminate reflections affect.
Emissivity: emissivity is meant object radiation or endergonic ability, it is the energy that under specific temperature, gives off of an object and at the ratio of the next desirable energy that radiator radiated of same temperature, the emissivity of different objects has nothing in common with each other, in order to guarantee thermometric accuracy, setting correct emissivity is prerequisite and basis.The method of definite emissivity commonly used has three kinds: look-up table, with reference to method (black tape method) and thermocouple method.More than in three kinds of methods, thermocouple method is the most reliable, the most accurately, when needs are accurately measured object surface temperature, the normal numerical value that adopts thermocouple method to determine infrared emittance, this tests electric apparatus temperature rise with traditional thermocouple method is different, does not need to lay a lot of points and carries out thermometric, as long as select a point, utilize two kinds of thermometric modes to carry out thermometric simultaneously, compare the result that both obtain, just can draw emissivity value accurately.
Detect distance: when selecting thermal infrared imager, spatial resolution should satisfy the requirement of measured distance.Satisfy safe distance under the situation, want to differentiate exactly product to be measured, the product image to be measured by the thermal imaging system optical system must account for 9 pixels, and is perhaps more; If instrument distance product to be measured is far away excessively, the product to be measured that is reflected on the thermal imaging system graphic interface will be very little, and since the temperature-averaging measured at this moment of thermal infrared imager the temperature of product to be measured itself and surrounding environment, temperature-measuring results can't correctly reflect the true temperature of product to be measured.Therefore, in order to obtain the most accurate survey measurements, thermal infrared imager should be tried one's best near tested equipment, makes tested equipment be full of whole visual field.But the distance of thermal imaging system and product to be measured can not be too little, is not less than the minimum focus of thermal imaging system optical system, otherwise can not be focused into distinct image.In general, distance 10 meters with interior relatively good, and when the thermal imaging system parameter is set, should use the actual range between instrument and the product to be measured as far as possible.
Environment temperature: generally should under environment temperature is not less than 5 ℃ condition, carry out infrared detection, the assignment of environment temperature can correctly be set by following method: record ambient temperature value by thermometer or thermopair, give the parameter assignment; Measure an environment temperature reference body, adjust the environment temperature of thermal infrared imager, make the measured temperature of environment temperature reference body and the value of the setting basically identical of environment temperature.
Detection angles and adjacent object heat radiation: because the essence of thermal infrared imager is to detect the infrared emanation of product to be measured, therefore should detect, to select best detection angles from multi-angle.Carry out at needs should writing down the detection position under the situation of repetition measurement, so that in same position probing, compare next time.General detection angles should be greater than 30 degree.
Ambient humidity: this parameter of ambient humidity is also important, need give the parameter assignment with the ambient humidity value of hygrometer actual measurement.Humidity is excessive, and gas molecules such as vapor in the atmosphere H2O selectively absorb the infrared radiation of certain wavelength, will influence the testing result of thermal infrared imager.
Guarantee that instrument is steady in the measuring process: in the photographic images process,, influence result's judgement because instrument moves and may cause image blurringly.Therefore in order to reach best effect, freeze with document image in, should guarantee as far as possible that instrument is steady; When pressing store button, should guarantee light and slowly and level and smooth as far as possible, avoid instrument shake, even slight instrument rocks, also may cause not fogging clear.Generally take to guarantee that with the firm method of stilt instrument is steady, or instrument is placed on body surface, or use tripod, keep stable as far as possible.In the utility model, the fine adjustment stage that is fixed with thermal infrared imager and optics camera is fixed with tripod, has guaranteed that state is steady in the apparatus measures process, not the carrying out of interference experiment.
The utility model electric equipment products accessible surface temperature rise device for fast detecting has following characteristics:
Infrared Thermography Technology is measured electric apparatus temperature rise and had real-time, and is ageing more intense, and the variation of detection electric apparatus temperature rise that can be real-time does not postpone;
It is the whole audience that Infrared Thermography Technology is measured electric apparatus temperature rise, so can be used for the electric apparatus temperature rise pre-detection, promptly before the cloth thermopair, detect with thermal infrared imager earlier, after recognizing the Temperature Distribution of electrical equipment, just can arrange thermopair accurately, can reduce greatly because of the thermopair inaccurate caused error of layouting;
Infrared measurement of temperature has untouchable, can directly measure owing to temperature height or other reasons make thermopair directly sites measured such as heating wire, electric heater etc.;
Thermal infrared imager can record each regional maximum temperature of electrical equipment surface accurately, can judge the particular location of each heat generating spot whether have temperature anomaly point very effective for quick investigation electrical equipment accessible surface fast in conjunction with optical camera system.
The infrared heat image instrument measuring electric apparatus temperature rise, by the temperature rise on electricity measurer surface with the image format of image be presented in the user in face of, what record no longer is the temperature rise of single point, but each temperature of whole is detected simultaneously, heating position just is easy in thermography as can be seen, especially in conjunction with optical imagery, can effectively prevent failing to judge of heating position.
