Embodiment 1
[0027] Coal transport trestle, as the basic guarantee for the fuel supply of the power plant, includes coal feeders, electronic belt scales, belt conveyors, coal plows and other coal-fired transportation equipment, and is a key area for equipment operation and maintenance. The coal transport trestle has a long line, relatively bad internal air environment, many equipment inspection sites, high coal dust content, and high requirements for operators' sense of responsibility and safety awareness. and other safety hazards. In the following, the area monitoring is realized based on the data processing method of the present invention through the portable infrared temperature measuring equipment MLX90640-D55 Thermal Camera installed in the equipment inspection area and the server connected through the private network.
[0028] Its working process is as follows:
[0029] Step 1: Obtain the temperature data array of the infrared sensor MLX90640-D55 Thermal Camera, and identify the 24*...

The invention discloses a data processing method for an infrared sensor, and the method comprises the following steps: obtaining a temperature data array of the infrared sensor, and marking the identification coordinates of each pixel point; acquiring the target temperature of each pixel of the infrared sensor on the current frame in real time, deleting the current frame when any target temperature is higher than a pre-stored upper threshold value or lower than a pre-stored lower threshold value, otherwise, skipping to the next step; traversing each 3 * 3 field in the data array, performing median filtering when the difference between any center pixel value and each pixel value around the center pixel value is greater than a preset value, and then jumping to the next step, otherwise, directly jumping to the next step; the highest value in the temperature data array is sent to a server; performing normalization processing on each pixel value; performing multiple linear difference on each pixel value; gradient detection is carried out in the horizontal and vertical directions; and visually displaying the data. According to the method, the contrast ratio of the infrared thermal image can be optimized, so that a suspected fault area which is heating can be positioned more accurately.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing method of an infrared sensor. Background technique [0002] An infrared sensor is a device that converts invisible infrared energy emitted by an object into temperature and displays it through thermal imaging. At present, infrared sensors have begun to be used in technical scenarios such as preventive maintenance, electrical inspection and troubleshooting of coal mining equipment. middle. But in practice, we found that the existing infrared sensors have the following defects: Based on the principle that infrared thermal imagers rely on temperature difference to achieve imaging, when the temperature difference of the measured object is small, the contrast of the infrared thermal image formed by it is low, resulting in details The ability to distinguish is deteriorated, and it is impossible to accurately locate the suspected fault area that is heating. T...
