[0044] like Figure 1 As shown, an embodiment of the present invention provides a method for monitoring the temperature of electrical equipment based on a split mobile thermal imager, which is applied to Figure 2 The split mobile thermal imager shown in FIG. 1 has an internal module structure as shown in FIG. Figure 3 shown.

[0045] The split mobile thermal imager comprises a mobile thermal imager body 1, on which an infrared temperature measuring probe 10 is arranged; and inside the mobile thermal imager body are arranged Figure 3 The fault diagnosis module 120 is shown.

[0046] In a preferred embodiment, the split mobile thermal imager further includes a body base 2 ; the body base 2 is used to place the movable thermal imager body 1 .

[0047] The split mobile thermal imager monitoring method comprises:

[0048] Step S1: holding the movable thermal imager body 1 so that the infrared temperature measuring probe 10 is aimed at the electrical equipment to be tested, and the distance between the infrared temperature measuring probe 10 and the electrical equipment to be tested is not greater than a first distance threshold;

[0049] Step S2: Acquire the infrared radiation energy of the electrical equipment to be detected through the infrared temperature measuring probe 10, and transmit the infrared radiation energy of the electrical equipment to be detected to the fault diagnosis module 120, so that the fault diagnosis module 120 generates an infrared thermal image of the electrical equipment to be detected according to the infrared radiation energy of the electrical equipment to be detected, and outputs the temperature information of the electrical equipment to be detected according to the infrared thermal image of the electrical equipment to be detected.

[0050] In step S1, the power distribution network power equipment inspector holds the movable thermal imager body 1 and aims the infrared temperature measuring probe 10 at the electrical equipment to be inspected, and when measuring the temperature, the measuring distance between the infrared temperature measuring probe 10 and the electrical equipment to be inspected is not greater than the first distance threshold, and the first distance threshold may be 20 mm, for example. By limiting the measuring distance by the first distance threshold, the infrared temperature measuring probe 10 can realize the non-contact measurement of the electrical equipment to be inspected, and it can also ensure that the ambient temperature does not interfere with the measurement when the electrical equipment to be inspected is measured non-contactly.

[0051] Regarding step S2, after the infrared temperature measuring probe 10 is aimed at the electrical device to be detected, the infrared temperature measuring probe 10 obtains the infrared radiation energy of the electrical device to be detected, and transmits the infrared radiation energy to the fault diagnosis module 120 built into the mobile thermal imager body 1. The fault diagnosis module 120 generates an infrared thermal image of the electrical device to be detected based on the infrared radiation energy of the electrical device to be detected, and then outputs the temperature information of the electrical device to be detected.

[0052] In a preferred embodiment, it also includes: by holding the movable thermal imager body 1, the distance between the infrared temperature measuring probe 10 and the electrical equipment to be detected is not greater than a second distance threshold, and the distance between the infrared temperature measuring probe 10 and the electrical equipment to be detected is not less than a first distance threshold; wherein the second distance threshold is greater than the first distance threshold; obtaining the ambient temperature of the electrical equipment to be detected through the infrared temperature measuring probe 10, and transmitting the ambient temperature to the fault diagnosis module 120.

[0053] Specifically, after step S2, the power equipment inspector of the distribution network measures the ambient temperature of the power equipment to be detected by using the handheld movable thermal imager body 1, and when measuring the temperature, the measuring distance between the infrared temperature measuring probe 10 and the electrical equipment to be detected is not greater than the second distance threshold and not less than the first distance threshold. By limiting the first distance threshold and the second distance threshold, it is ensured that the measured ambient temperature does not overlap with the infrared radiation energy measurement area, thereby reducing the interference received from the power equipment to be detected when measuring the ambient temperature. By limiting the second distance threshold, it can be ensured that the measured ambient temperature is the temperature of the environment surrounding the power equipment to be detected. After completing the measurement of the ambient temperature, the measured ambient temperature is transmitted to the fault diagnosis module 120 for fault diagnosis.

[0054] In a preferred embodiment, Figure 2 As shown, the movable thermal imager body 1 is further provided with an infrared receiving module 110, the infrared receiving module 110 comprises: an infrared receiving unit, a first storage unit and a first interface unit, and the infrared receiving module 110 is electrically connected to the fault diagnosis module 120;

[0055] The method of obtaining infrared radiation energy of the electrical device to be detected by the infrared temperature measuring probe 10 and transmitting the infrared radiation energy of the electrical device to be detected to the fault diagnosis module 120 includes:

[0056] The infrared radiation energy of the electrical device to be detected is obtained by the infrared temperature measuring probe 10, and the infrared radiation energy of the electrical device to be detected is transmitted to the infrared receiving module 110 through the infrared temperature measuring probe;

[0057] The infrared receiving unit receives infrared radiation energy from the electrical equipment to be detected, converts the infrared radiation energy from the electrical equipment to be detected into an electrical signal of the electrical equipment to be detected, stores the electrical signal in the first storage unit, and transmits the electrical signal to the fault diagnosis module 120 through the first interface unit.

[0058] Preferably, the infrared receiving module 110 can also obtain parameters of the infrared temperature measuring probe 10, such as field of view angle, resolution, focal length and minimum resolution temperature difference.

[0059] In a preferred embodiment, the field of view angle of the infrared temperature measuring probe 10 is not less than 42 degrees.

[0060] Specifically, Figure 4 As shown, the field of view angle of the infrared temperature measuring probe 10 of the present invention is as high as 42 degrees, which can achieve a wider field of view for collecting infrared radiation energy of the electrical equipment to be detected at the same measuring distance, so that the final infrared thermal imaging can more comprehensively describe the temperature information of the electrical equipment to be detected and the distribution of temperature values ​​of each pixel point, which is beneficial for operation and maintenance personnel to intuitively and conveniently understand the temperature rise transition and temperature distribution state of the electrical equipment to be detected, and assist operation and maintenance personnel to improve the efficiency of electrical equipment maintenance and fault prevention.

[0061] In a preferred embodiment, the fault diagnosis module 120 includes: a second interface unit and an image processing unit;

[0062] The fault diagnosis module 120 generates an infrared thermal image of the electrical device to be detected according to the infrared radiation energy of the electrical device to be detected, and outputs temperature information of the electrical device to be detected according to the infrared thermal image of the electrical device to be detected, including:

[0063] The second interface unit receives the electrical signal and transmits the electrical signal to the image processing unit, so that after receiving the electrical signal, the image processing unit performs pseudo-color image enhancement processing on the electrical signal according to a preset image processing algorithm to generate an infrared thermal imaging of the electrical equipment to be detected, and outputs temperature information of the electrical equipment to be detected based on the infrared thermal imaging of the electrical equipment to be detected; wherein the temperature information includes the temperature value of each pixel point of the infrared thermal imaging.

[0064] Specifically, in this embodiment, the image processing unit supports the processing of 10 different image colors, and supports custom switching of suitable image color scenes according to different application scenarios. It mainly transforms the grayscale image into a pseudo-color image through a preset image processing algorithm, i.e., the cv.applyColorMap function. After the image processing unit receives the electrical signal of the electrical equipment to be detected, it reads the built-in color scheme of Matplotlib to construct a multi-channel LUT, or customizes the multi-channel LUT, and replaces the grayscale corresponding to the temperature value through the table lookup function cv.LUT, generates the corresponding infrared thermal imaging, realizes 10 kinds of custom color style transformation, and achieves the effect of image enhancement display. The infrared thermal imaging generated in this way can highlight the temperature value distribution of each pixel in the infrared thermal imaging, and can intuitively see the pixel corresponding to the highest temperature value and the pixel corresponding to the lowest temperature value, which is convenient for the operation and maintenance personnel to observe the temperature distribution of the power equipment to be detected. Preferably, the infrared thermal imaging of the electrical equipment to be detected generated by the image processing unit is an infrared thermal imaging of 576*768 pixels.

[0065] In a preferred embodiment, the fault diagnosis module 120 further includes: a temperature diagnosis unit, an alarm unit, a communication unit and a second storage unit;

[0066] The image processing unit is further used to determine the temperature difference between the temperature value of each pixel point of the infrared thermal imaging and the ambient temperature according to the infrared thermal imaging of the electrical equipment to be detected and the ambient temperature of the electrical equipment to be detected, and transmit the temperature difference value of each pixel point of the infrared thermal imaging and the temperature information of the electrical equipment to be detected to the temperature diagnosis unit, so that when the temperature difference value of any pixel point exceeds the preset temperature difference range threshold or the temperature of any pixel point exceeds the preset temperature range threshold, the temperature diagnosis unit transmits the infrared thermal imaging and the temperature values ​​corresponding to the pixels exceeding the preset temperature difference range threshold to the alarm unit;

[0067] The alarm unit generates alarm information according to the infrared thermal imaging and the temperature values ​​corresponding to the pixels exceeding the preset temperature difference range threshold, and stores the alarm information in the second storage unit;

[0068] The second storage unit transmits the alarm information to the remote terminal 130 via the communication unit.

[0069] Specifically, in this embodiment, the temperature diagnosis unit determines whether the temperature or temperature rise of the power equipment to be detected is abnormal based on the infrared thermal imaging with temperature information and the ambient temperature of the power equipment to be detected measured above, and then sends out alarm information in time in combination with the alarm unit, the second storage unit and the communication unit. In the temperature diagnosis unit, if the temperature of any pixel of the electrical equipment to be detected is greater than 90 degrees Celsius or the temperature difference of any pixel is greater than 75 degrees Celsius, it is considered that the surface temperature of the power equipment to be detected has a serious abnormal heating condition, and the corresponding information is transmitted to the alarm unit, and the alarm unit generates a "crisis defect" alarm signal, which is stored in the second storage unit and sent to the remote terminal 130 through the second storage unit and the communication unit. If the temperature of any pixel of the power equipment to be detected is greater than 75 degrees Celsius or the temperature difference of any pixel is greater than 65 degrees Celsius, it is considered that the surface temperature of the power equipment to be detected has a serious heating condition, and the corresponding information is transmitted to the alarm unit, and the alarm unit generates a "serious defect" alarm signal, which is stored in the second storage unit and sent to the remote terminal 130 through the second storage unit and the communication unit. If the temperature of any pixel of the power equipment to be detected is greater than 60 degrees Celsius or the temperature difference of any pixel is greater than 30 degrees Celsius, it is considered that the surface temperature of the power equipment to be detected is slightly heated, and the corresponding information is transmitted to the alarm unit, which generates a "general defect" alarm signal, stores it in the second storage unit, and then sends it to the remote terminal 130 through the second storage unit and the communication unit. If the temperature of any pixel of the power equipment to be detected is less than or equal to 60 degrees Celsius or the temperature difference of any pixel is less than 30 degrees Celsius, it is considered that the surface temperature of the power equipment to be detected is normal, and there is no need to send an alarm signal.

The remote terminal 130 can be a computer, mobile terminal, etc. that can establish a communication connection. After the remote terminal 130 establishes a connection with the communication unit, in addition to receiving alarm information, the communication unit can also obtain information such as infrared thermal imaging of the power equipment to be detected, the temperature value of each pixel point, the temperature distribution, and the temperature difference between the temperature value of each pixel point and the ambient temperature. After obtaining this information, it is visualized on the remote terminal 130.

Preferably, when the remote terminal 130 is a mobile terminal such as a mobile phone, it can establish a communication connection with the movable thermal imager body 1 through a communication unit, and then the mobile terminal can be adsorbed on the back plate of the movable thermal imager body 1, so as to realize real-time viewing of the measurement data.
