Description

Turnout heating monitoring method, system, storage medium and electronic device Technical Field

[0001] The present invention relates to the technical field of turnout snow melting, and in particular to a turnout snow melting monitoring method, system, computer-readable storage medium and electronic equipment. Background Art

[0002] Existing turnout snowmelt monitoring systems determine the operating status of electric heating elements by collecting the total current. When a low-power electric heating element fails, the total current is minimally affected, so the system may not accurately identify whether the heating element is faulty. Furthermore, when an electric heating element alarm sounds, maintenance personnel must inspect all heating elements to identify the faulty element. This requires a team of at least two people, increasing labor costs and reducing maintenance efficiency.

[0003] Another type of turnout snowmelt monitoring system uses a collector to collect the current, voltage, resistance, insulation status, and other information of the electric heating element to determine its operating status. This method is limited to systems that use electric heating elements for snowmelt and cannot accurately monitor the specific electric heating element that has failed. In order to accurately monitor the failed electric heating element, each electric heating element needs to be connected to a collector so that the faulty electric heating element can be accurately determined. However, this method also requires the electric heating elements and collectors to be numbered so that the faulty electric heating element can be easily found. The process is relatively cumbersome, and setting up multiple collectors increases costs.

[0004] Summary of the Invention

[0005] In response to the above problems, the present invention proposes a turnout snowmelt monitoring method, system, computer-readable storage medium and electronic device. Without changing the existing monitoring nodes, infrared thermal imaging detectors can be installed around the turnout to achieve accurate and real-time monitoring of the working status of the heating device and reduce costs.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] FIG1 is a flow chart of a method for monitoring turnout heating according to an embodiment of the present invention. As shown in FIG1 , the method for monitoring turnout heating according to an embodiment of the present invention specifically includes the following steps:

[0040] S101: Start the heating device to heat the turnout.

[0041] Each side of the turnout includes a point rail and a heart rail, which are connected in sequence. A heating device is installed on the sides of the point rail and the heart rail. The heating device can be installed on the sides of the point rail and the heart rail through an existing installation device.

[0042] Multiple heating devices are installed on the sides of the turnout. A common practice is to install heating devices starting at about 2m from the initial position of the point rail. Four heating devices are then installed at intervals of 4.7m, 4.7m, 4.7m, and 3.72m. Two heating devices are then installed at intervals of 4.7m and 3.72m on the point rail. Six heating devices are installed on each side of the turnout, for a total of twelve.

[0043] The above are just examples to illustrate the installation position and number of heating devices. In actual applications, the number and spacing of heating devices may vary depending on the type of turnout.

[0044] The heating device generates heat energy when working and transfers the heat energy to the switch by means of heat radiation and heat conduction, thereby heating the switch and evaporating the snow and ice above the switch, thereby achieving the purpose of snow and ice removal.

[0045] In this embodiment, the heating device is an electric heating device. After the electric heating device is powered on, it can convert electrical energy into heat energy and transfer it to the outside.

[0046] S102: Acquire an infrared image of the turnout.

[0047] Infrared imaging, short for thermal infrared imaging, also known as thermal imagery, is an image formed by infrared thermal imaging detectors receiving and recording the thermal radiation energy emitted by a target object. Thermal infrared imaging, a form of thermal radiation imaging, emerged with the advent of infrared imaging technology. Infrared imaging is a thermal radiation information detection technology that uses infrared radiation differences from an object to generate an image. Infrared thermal imaging systems can convert the naturally emitted infrared radiation distribution from an object's surface into a visible image. Because different objects, or different parts of the same object, typically have different thermal radiation characteristics, such as temperature differences and emissivity, objects in the thermal infrared image are distinguished by their differences in thermal radiation. Thermal infrared imagery is independent of external light and can be acquired in any weather.

[0048] Specifically, infrared thermal imaging detectors are installed around the turnout to capture infrared images of the turnout. This can be accomplished by fixing upright posts to the ground around the turnout, installing rotating brackets on the posts, and then mounting the infrared thermal imaging detectors on the rotating brackets. This is just an example of how to install an infrared thermal imaging detector. In actual applications, technicians can design other more suitable structures for installing infrared thermal imaging detectors based on the actual surrounding environment and location.

[0049] Specifically, one infrared image may be taken for each of the point rail and the center rail on both sides of the turnout, for a total of four images.

[0050] S103: Determine the temperature of the switch based on the infrared image.

[0051] A total of four infrared images were taken for a set of switches. During the monitoring process, the four infrared images can be monitored simultaneously or one by one, depending on the operating capacity of the equipment.

[0052] Step S103 specifically includes the following steps:

[0053] S1031: Obtain the RGB value of the infrared image.

[0054] The RGB color model is an industry standard that creates a wide variety of colors by varying and superimposing the three color channels: red (R), green (G), and blue (B). RGB represents the colors of the three channels, red, green, and blue. This standard encompasses nearly every color perceptible to human vision and is one of the most widely used color systems. All colors on a computer screen are created by mixing these three colors in varying proportions. A combination of red, green, and blue is the smallest display unit. Any color on a screen can be recorded and expressed by a set of RGB values.

[0055] One infrared image of the turnout is selected from four images taken by an infrared thermal imaging detector, a pixel point is randomly selected on the selected infrared image, and the RGB value of the pixel point is determined based on the selected pixel point.

[0056] As another possible implementation method, multiple pixels can be selected from the selected infrared image, which can be three pixels or four pixels, etc., and the RGB value of each selected pixel can be determined. The RGB mean of the selected multiple pixels can be calculated and used to represent the RGB value of the acquired infrared image.

[0057] In order to more accurately reflect the RGB value of the acquired infrared image when selecting multiple pixels to calculate the RGB mean, when selecting multiple pixels, multiple pixels are selected at intervals. It is best that the selected multiple pixels are evenly distributed in the same infrared image, and the multiple pixels are distributed at equal intervals.

[0058] S1032: Determine the temperature of the switch based on the RGB value.

[0059] The RGB value of a selected pixel or the RGB average of multiple selected pixels is used to find the temperature represented by the RGB value of this pixel in the RGB value and temperature comparison table. The determined temperature is the temperature of the turnout.

[0060] S104: When the temperature of the switch is lower than the temperature threshold, it is confirmed that there is a fault in the heating device.

[0061] When determining the temperature threshold, at least two of the four infrared images may be selected and the average temperature of the at least two selected infrared images may be obtained, and the average temperature may be used as the temperature threshold. To ensure the accuracy of the threshold, a plurality of infrared images may be selected, such as three or four images in proportion.

[0062] Since the heating device converts electrical energy into thermal energy and transmits it to the switch, causing the switch temperature to rise, when the heating device is heating the switch and the monitored switch temperature is lower than the temperature threshold, it means that the switch temperature is not high enough and has not received enough thermal energy from the heating device, thereby inferring that the heating device is faulty.

[0063] When the temperature of the switch is higher than the temperature threshold, it is confirmed that the heating device is heating the switch normally and there is no fault in the heating device; then, the infrared thermal imaging detector can continue to re-acquire another infrared image in the next time period and repeat the above steps to realize real-time monitoring of the working status of the heating device.

[0064] According to an embodiment of the present invention, optionally, step S104 may further include outputting an alarm message when a failure occurs in the heating device.

[0065] When it is confirmed that the heating device has a fault, an alarm message is issued to prompt maintenance personnel to repair or replace the faulty heating device as soon as possible.

[0066] FIG2 is a schematic diagram of the structure of a turnout heating monitoring system provided by an embodiment of the present invention; FIG3 is a schematic diagram of the structure of another turnout heating monitoring system provided by an embodiment of the present invention. An embodiment of the present invention further provides a turnout heating monitoring system, as shown in FIG2 , which includes:

[0067] Heating module 201, used for heating the turnout;

[0068] Acquisition module 202, used to acquire infrared images of the turnout;

[0069] The processing module 203 determines the temperature of the turnout based on the infrared image, and when the temperature of the turnout is lower than a temperature threshold, it is determined that the heating module 201 has a fault.

[0070] As shown in FIG3 , as another possible implementation, the system further includes:

[0071] The alarm module 204 is used to output an alarm message when a failure occurs in the heating module 201 .

[0072] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0073] The temperature of the turnout is determined by taking an infrared image of the turnout and compared with a temperature threshold. When the temperature of the turnout determined by the infrared image is lower than the temperature threshold, it means that the turnout temperature does not meet the standard and it fails to receive sufficient heat energy from the heating device, thereby inferring that the heating device is faulty. This method can realize remote real-time monitoring of the working condition of the heating device, and can also accurately determine the specific location of the faulty heating device through the location of the temperature that does not meet the standard in the image, so that maintenance personnel can repair or replace the faulty heating device in a timely and accurate manner, reducing the time for maintenance personnel to find the faulty heating device, improving maintenance work efficiency, and reducing labor costs.
