The utility model discloses can carry out the normalization correction to power equipment's temperature measurement data in real time according to the current amblent air temperature condition, reduce influenced by the amblent air temperature factor, reach the purpose to the accurate temperature measurement in the crucial position of power equipment.
Description
Technical field
The utility model relates to a kind of power equipment temp measuring system, the online accurate temperature measurement system of especially a kind of power equipment.
Background technology
Existing power equipment infrared measurement of temperature mainly contains as under type: 1, adopt handheld thermometer; 2, intelligent robot is adopted; 3, online monitoring.Handheld thermometer, personnel specialty of being taken pictures quality, environmental influence are serious, and can not monitoring electrical equipment running status in real time, and temperature measurement data truly cannot reflect the state of equipment under certain environmental conditions; Intelligent robot thermometric not only affects by amblent air temperature, wants accurate positioning equipment to detect position simultaneously and also has problems; Present Domestic is outer to be carried out about online infrared measurement of temperature monitoring, but thermometric mode is rough, does not reach the object of power equipment key position accurate temperature measurement.And these temperature sensing meanses are confined to thermal map candid photograph, ex-post analysis more or are confined to the thermometric object thermometric of same picture fixed qty.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of minimizing to affect by amblent air temperature factor, realize the thermometric of real-time video full frame and observed temperature can reflect the online accurate temperature measurement system of the power equipment of the true running status of equipment, to overcome the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
The online accurate temperature measurement system of a kind of power equipment, the formation of this system comprises online infrared imaging temperature measuring instrument, A/D converter and supervisory control comuter, online infrared imaging temperature measuring instrument is used for the power equipment infrared chart of shot detection point, and the infrared chart simulating signal that the infrared chart that output packet contains measured temperature is correlated with; A/D converter is used for the infrared chart simulating signal that online infrared imaging temperature measuring instrument exports being transformed to infrared digital signal and passing to supervisory control comuter; Online infrared imaging temperature measuring instrument connects A/D converter, and A/D converter is connected with supervisory control comuter; Temperature sensors of high precision, air velocity transducer and humidity sensor are installed near the power equipment of check point.
In the online accurate temperature measurement system of above-mentioned power equipment, online infrared imaging temperature measuring instrument is pan and tilt head binocular camera, has a visible channel and an infrared channel, can take infrared chart and the visible images of power equipment simultaneously.
The beneficial effects of the utility model: compared with prior art, the utility model can in real time according to current environment climatic condition, correction is normalized to the temperature measurement data of power equipment, reduces and affect by amblent air temperature factor, reach the object to power equipment key position accurate temperature measurement.
Accompanying drawing explanation
Fig. 1 is structural principle block diagram of the present utility model;
Fig. 2 is principle of work schematic diagram of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment
Embodiment 1.As shown in Figure 1, comprise online infrared imaging temperature measuring instrument, A/D converter and supervisory control comuter, online infrared imaging temperature measuring instrument is used for the power equipment infrared chart of shot detection point, and the infrared chart simulating signal that the infrared chart that output packet contains measured temperature is correlated with; A/D converter is used for the infrared chart simulating signal that online infrared imaging temperature measuring instrument exports being transformed to infrared digital signal and passing to supervisory control comuter; Online infrared imaging temperature measuring instrument connects A/D converter, and A/D converter is connected with supervisory control comuter; Temperature sensors of high precision, air velocity transducer and humidity sensor are installed near the power equipment of check point, environmental baseline is normalized.For current caused hot type equipment, can be the temperature of 20 DEG C to temperature by the temperature recorded under low temperature conversion, convert the heat radiation impact that wind speed causes, formula be as follows: T simultaneously
20=β T
s+ (20 – T
0)/α
2, wherein: T
20for conversion is to equipment connection point overtemperature (DEG C) when 20 DEG C, T
sfor apparatus overheat point temperature (DEG C) during test, T
0for environment temperature (DEG C) during test, α is temperature conversion factor, and β is wind speed conversion factor.Online infrared imaging temperature measuring instrument adopts pan and tilt head binocular camera, has a visible channel and an infrared channel, can take infrared chart and the visible images of power equipment simultaneously.
Principle of work: as shown in Figure 2, online infrared imaging temperature measuring instrument 1 is in the process of transmission infrared video code stream 2, carry full video temperature measurement data 3 simultaneously, supervisory control comuter can realize on real-time video, carry out the analysis of line temperature to electric device maintenance position, isothermal analysis, temperature gradient distributional analysis and maximum sustained load heat spot temperature analysis, also full video temperature measurement data 3 can be carried out video recording together with infrared video code stream 2 data to store, the line temperature of being carried out electric device maintenance position by video recording is analyzed, isothermal analysis, temperature gradient distributional analysis and maximum sustained load heat spot temperature analysis.
