Description

Technical Field

[0001] This utility model belongs to the field of railway freight car safety operation monitoring technology, and in particular relates to a device specifically for monitoring and early warning of heat sources in vehicles undergoing station maintenance and repair. Background Technology

[0002] Currently, railway freight station maintenance yards are characterized by frequent vehicle entry and exit, concentrated welding and repair work, and highly concealed heat sources. Traditional manual inspection methods are no longer sufficient to meet the demand for rapid and accurate early warning of heat sources in repaired vehicles. For this specific scenario of monitoring and early warning of heat sources in repaired vehicles, a dedicated and effective technological means is still lacking. Therefore, there is an urgent need to develop a device capable of real-time monitoring of heat sources on the vehicle body at the exit, providing anomaly alarms, and recording the entire process via video. This would comprehensively improve the accuracy of fire hazard perception and response efficiency during station maintenance operations, providing reliable technical assurance for the safe release of repaired vehicles. Utility Model Content

[0003] The present invention aims to provide a heat source monitoring and early warning device for vehicles undergoing maintenance at a repair station, in order to address the deficiencies in the aforementioned background technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a heat source monitoring device for vehicles undergoing maintenance at railway freight stations, comprising a bracket, an infrared detector, a standard thermal imaging binocular camera, a high-performance thermal imaging binocular camera, a data processing module, a communication transmission line, and a display terminal. The device is characterized in that: the bracket is hoisted and installed at the exit of the railway freight station maintenance yard; at least one infrared detector is installed on the crossbeam of the bracket to monitor incoming vehicles; and a high-performance thermal imaging binocular camera is installed in the middle of the crossbeam of the bracket, cantilevered, to image the top of the vehicle and the inner wall of the carriage; a standard thermal imaging binocular camera is installed on both sides of the crossbeam of the bracket, cantilevered, one on each side, to image the outer walls of both sides of the vehicle; the infrared detector, the standard thermal imaging binocular camera, and the high-performance thermal imaging binocular camera are respectively connected to the data processing module through the communication transmission line, and the data processing module is electrically connected to the display terminal through a wireless transmission line.

[0005] Furthermore, the support includes a crossbeam and two hangers, wherein the hangers are fixedly connected to the crossbeam in a suspended manner above.

[0006] Furthermore, the boom consists of two telescopic cylinders, upper and lower, and the length is adjusted between the two telescopic cylinders via a screw structure.

[0007] Furthermore, a threaded sleeve is fixedly installed inside one of the telescopic cylinders. The threaded sleeve is threadedly connected to a lead screw. The lower end of the lead screw is rotatably installed inside another telescopic cylinder. The lower end of the lead screw is mechanically connected to the handle via a bevel gear set.

[0008] Furthermore, it also includes an alarm module, which is connected to the data processing module via a communication transmission line.

[0009] Furthermore, the data processing module is an industrial control computer.

[0010] Furthermore, the display terminal is a networked PC or a smartphone.

[0011] Furthermore, the standard thermal imaging binocular camera is mounted at the end of the crossbeam in an inclined state via wedge blocks.

[0012] The beneficial effects of this utility model are: 1. Ensure the quality of repairs for vehicles undergoing emergency repairs. By using a thermal imaging monitoring system to detect abnormal heat sources on vehicles leaving the depot for repair, it is possible to effectively identify whether there are residual high-temperature points or uncooled parts in the welded parts of the vehicle body. This ensures that the heat source status of the vehicle body meets safety requirements after the operation is completed, thereby improving the quality of repaired vehicles, reducing the risk of rework, and promoting closed-loop management of maintenance operation quality.

[0013] 2. Eliminate fire safety risks and hazards associated with temporary vehicle repairs. The system enables continuous 24 / 7 heat source monitoring and intelligent alarm linkage, allowing for the detection and handling of abnormal fire sources before vehicles leave the depot. This prevents vehicle fires caused by residual high temperatures, minimizes the risk of vehicles leaving the depot with defects after repair, and effectively reduces the probability of fire accidents in the station repair area.

[0014] 3. Collect video and image data of vehicles repaired at the work site. The system has the function of recording high-definition visible light and thermal imaging images simultaneously throughout the entire process. It can establish a complete pre-departure heat source monitoring image file for each repaired vehicle, which facilitates future review, accountability and technical improvement, and provides detailed data support for standardized operation management and quality assessment.

Detailed Implementation

[0022] This embodiment will be described in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 6 The series of illustrations in the document introduces a heat source monitoring device for vehicles undergoing on-site repair and maintenance. This device is used to monitor the temperature of weld points on vehicles undergoing on-site repair and maintenance, for example, to prevent injuries caused by high temperatures. The device includes a bracket 100, a heat source monitoring module, a vehicle motion monitoring module, a data processing module, and a communication transmission line.

[0023] The bracket 100 is fixed in a suitable position and has a height adjustment function to ensure the accurate positioning of the heat source monitoring module and the vehicle motion monitoring module, so as to obtain accurate three-dimensional heat source monitoring information of the vehicle body.

[0024] More specifically, the bracket 100 includes a crossbeam 110 and two suspension rods 120, which are fixedly connected to the crossbeam 110 in a suspended manner. Each suspension rod 120 is a telescopic cylinder 121 assembly, consisting of upper and lower telescopic cylinders 121. The length of the two telescopic cylinders 121 is adjusted via a screw 123 structure. Specifically, the two telescopic cylinders 121 are nested together. A threaded sleeve 122 is fixedly installed inside the upper telescopic cylinder 121, and this threaded sleeve 122 is threadedly connected to the screw 123. The lower end of the screw 123 is rotatably mounted inside the lower telescopic cylinder 121 via a bearing 124. The lower end of the screw 123 is mechanically connected to a handle via a bevel gear set 125. Rotating the handle 126 drives the screw 123 to rotate, thereby adjusting the length of the suspension rod 120.

[0025] Furthermore, the bracket 100 is preferably installed at the exit of the railway freight car station maintenance yard to monitor the entering and exiting railway freight cars.

[0026] Heat source monitoring module: A high-performance thermal imaging binocular camera 200 is installed at the top center of the support beam 110 to view the heat sources on the top of the vehicle body and the sides of the inner wall of the carriage, and to assist in imaging; two standard thermal imaging binocular cameras 300 are installed on both sides of the support beam 110 to achieve lateral blind spot filling and auxiliary identification, forming a three-dimensional heat source monitoring layout for the vehicle body.

[0027] Furthermore, a wedge-shaped block 127 is also provided at the end of the crossbeam where the standard thermal imaging binocular camera 300 is located. The presence of this wedge-shaped block 127 ensures that the standard thermal imaging binocular camera 300, in its installed state, always faces the outer wall of the vehicle body for imaging. (Refer to...) Figure 1 and Figure 2 .

[0028] Furthermore, the high-performance thermal imaging binocular camera 200 and the standard thermal imaging binocular camera 300 are electrically connected to the data processing module through different communication transmission lines to process the data.

[0029] Vehicle motion monitoring module: An infrared detector 400 is installed at each end of the high-performance thermal imaging binocular camera 200 at the top center of the support beam 110. These infrared detectors 400 are electrically connected to the data processing module via different communication transmission lines for data processing. When a vehicle is shunted after maintenance at the station, the infrared detectors 400 are triggered, activating the binocular camera in the heat source monitoring module. The binocular camera performs real-time monitoring of the vehicle's heat source at the exit, provides anomaly alarms, and records the entire process video.

[0030] The data processing module is connected to the binocular camera and the infrared detector 400 circuit respectively, and is used to analyze and process the uploaded information.

[0031] Infrared detector 400 collects information about the presence or absence of vehicles in the environment, triggering a start signal from the data processing module. The binocular camera then starts and collects image information of the vehicle's body temperature. Both types of image information are directly uploaded to the data processing module. The data processing module uses an abnormal heat source and image matching algorithm to identify the temperature distribution of the truck's body in the environment, and determines whether the temperature is within the normal range based on changes in these heat source points.

[0032] The aforementioned binocular camera and infrared detector 400 are connected to the data processing module via a communication transmission line. This data processing module can be an industrial control computer, which is electrically connected to a cloud server via a wireless transmission line to achieve data interaction.

[0033] It also includes an alarm module, which is electrically connected to the data processing module via a communication transmission line. When the local temperature of the vehicle body exceeds a preset value, the alarm module will issue an audible alarm and a fire alarm, allowing on-site personnel to take immediate action.

[0034] The implementation of this technology involves using a thermal imaging binocular camera to acquire multi-view images of the heat sources on the railway freight car body. This allows for comprehensive monitoring of the car body's heat sources from different angles, enabling accurate capture of heat source information and timely detection of potential heat source anomalies. The car body motion monitoring module monitors and identifies the car body's shunting movement, accurately determining whether the car is in a departure state, thus achieving effective monitoring of the car body's heat sources at specific times. The bracket 100 plays a crucial role in fixing the heat source monitoring module and the car body motion monitoring module. Furthermore, the effective height of the bracket 100 is adjustable, ensuring that each monitoring module is in an accurate position during shunting after station maintenance, stably acquiring the car body's heat source information and guaranteeing the accuracy and reliability of the monitoring data.
