Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to an infrared imaging terminal for testing track circuits. Background Art

[0002] Thermal imaging technology plays an important role in the daily maintenance of railway electrical power panels. The power panel is one of the core equipment of the railway signal system, responsible for providing stable and reliable power for signal equipment. Since the power panel contains a large number of electronic components and connecting cables, it is easy to have problems such as poor contact and device aging during long-term operation, resulting in local temperature rise. If these problems are not handled in time, they may cause power panel failure, affect the normal operation of the signal system, and even endanger driving safety.

[0003] In the traditional manual maintenance mode, maintenance personnel need to check each component inside the power panel one by one, and rely on experience to determine whether it is overheating. This method is not only inefficient, but also has safety hazards. First, manual inspection is difficult to cover all components, and it is easy to miss potential problems; second, maintenance personnel may be exposed to dangerous factors such as high voltage and high temperature during the inspection process, which poses certain safety risks. Traditional thermal imaging equipment is usually handheld or fixed, and has the following limitations: Inconvenient operation: Handheld thermal imaging equipment requires maintenance personnel to operate it by hand, and long-term work can easily lead to fatigue, affecting detection efficiency and quality.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Thermal imaging technology plays an important role in the daily maintenance of railway electrical power panels. The power panel is one of the core equipment of the railway signal system, responsible for providing stable and reliable power for signal equipment. Since the power panel contains a large number of electronic components and connecting cables, it is easy to have problems such as poor contact and device aging during long-term operation, resulting in local temperature rise. If these problems are not handled in time, they may cause power panel failure, affect the normal operation of the signal system, and even endanger driving safety.

[0023] In the traditional manual maintenance mode, maintenance personnel need to check each component inside the power panel one by one, and rely on experience to determine whether there is overheating. This method is not only inefficient, but also has safety hazards. First, manual inspection is difficult to cover all components, and it is easy to miss potential problems; second, maintenance personnel may be exposed to dangerous factors such as high voltage and high temperature during the inspection process, which poses certain safety risks. Traditional thermal imaging equipment is usually handheld or fixed, and has the following limitations: Inconvenient operation: Handheld thermal imaging equipment requires maintenance personnel to operate it by hand, and long-term work can easily lead to fatigue, affecting detection efficiency and quality. Therefore, refer to Figure 1-4 This scheme designs a track circuit test infrared imaging terminal, including an outer shell 1, an infrared imager 2, a laser transmitter 3, a display screen 4, and a fixing frame 5.

[0024] The outer shell 1 is rotatably connected to both ends of the fixing frame 5, so that the outer shell 1 can be rotated up and down on the fixing frame 5. At the same time, a fixing belt 6 is fixedly connected to the fixing frame 5, and the fixing belt 6 is used to hang on the neck, so there is no need to manually control the movement of the outer shell 1. In order to improve the comfort, a chest frame 7 is fixedly connected to the end of the fixing frame 5. The chest frame 7 is arc-shaped and is used to fit the human chest and is used to directly contact the font instead of the fixing frame 5. At the same time, it is used to fix the fixing frame 5. In addition, in order to further improve the comfort, a fixing plate 8 is fixedly connected to the fixing belt 6 at the neck position. The fixing plate 8 increases the contact area and reduces the pressure. At the same time, it fits the position of the spine and better bears the force.

[0025] The display screen 4 is fixed on the upper end surface of the outer shell 1 to display the infrared layer. The infrared imager 2 and the laser transmitter 3 are both arranged in the outer shell 1. The display screen 4 is electrically connected to the infrared imager 2. The infrared imager 2 uses an infrared array sensor with a pixel of 32×24 for temperature acquisition. The sensor can monitor the surface temperature of the object being measured in real time and output the temperature information in the form of a matrix, that is, each pixel corresponds to a temperature value. The detection distance and angle of the infrared array sensor can be adjusted according to actual needs to meet the measurement requirements in different application scenarios.

[0026] The temperature collection process is as follows:

[0027] The infrared array sensor scans the object to be measured and collects the infrared radiation energy of each pixel. The infrared detector inside the sensor converts the received infrared radiation energy into an electrical signal. After amplification, filtering and other processing, the electrical signal is converted into a digital signal. The digital signal is transmitted to the signal processing unit for subsequent temperature calculation and processing.

[0028] The imaging process is as follows:

[0029] The signal processing unit receives the digital signal from the infrared array sensor and extracts the temperature data of each pixel. The temperature data is normalized so that it is within a suitable temperature range for subsequent image processing. According to the temperature value of each pixel, a corresponding grayscale value is assigned to it. Generally, the higher the temperature, the larger the grayscale value; the lower the temperature, the smaller the grayscale value. In this way, a grayscale image can be obtained, showing the temperature distribution of the object being measured.

[0030] In order to more intuitively display the temperature distribution, the grayscale image can be processed with pseudo color. By setting different temperature ranges to different colors, a color image can be obtained, making it easier for observers to distinguish the temperature differences in different areas. The resulting temperature image can be displayed in real time on a display screen or other display device for maintenance personnel to view and analyze.

[0031] Since the use environment is generally in a high temperature state, and the summer temperature is superimposed, an air pump 9 is provided inside the outer shell 1, and the air inlet of the air pump 9 is arranged at the lower end of the outer shell 1, and an air duct 10 is provided inside the outer shell 1, and one end of the air duct 10 is connected with the infrared imager 2, and a telescopic tube 11 is connected and fixedly connected to the chest frame 7, and one end of the telescopic tube 11 is connected with the air duct 10. A plurality of heat dissipation holes 12 are provided on the outer shell 1 and the chest frame 7. Through the action of the air pump 9, the air duct 10 is used to drive the airflow into the infrared imager 2 and the chest frame 7, and the air is blown to dissipate the heat of the infrared imager 2 while blowing the human body, so that it can be used comfortably in hot weather.

[0032] Since the position of the body is not as accurate as that of the hands, NIO provides corresponding indication signs. A lens 13 is slidably connected inside the outer shell 1. The lens 13 is arranged at the front end of the laser emitter 3. The upper end of the lens 13 is fixedly connected to a slider 14. The slider 14 is arranged outside the outer shell 1. The position of the lens 13 is controlled by the slider 14, so as to adjust the diffusion degree of the light emitted by the laser emitter 3, so as to better indicate the current corresponding measurement position.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
