Technical Field

[0001] This utility model belongs to the field of railway coal transportation technology, and in particular relates to an online temperature monitoring system and device for railway coal transportation. Background Technology

[0002] When coal is stored for a long time, it absorbs oxygen, and the oxidation of its components generates heat, leading to spontaneous combustion. Spontaneous combustion of coal is a slow process that begins from the inside. Temperature monitoring can detect abnormal temperatures inside the coal pile in a timely manner. These abnormalities are often precursors to spontaneous combustion, and timely intervention can prevent such accidents.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0020] Coal transported by rail carries the risk of spontaneous combustion, such as... Figures 1-6 As shown, an online temperature monitoring system for railway coal transportation and an apparatus applied to the system are disclosed. The online temperature monitoring system for railway coal transportation includes a temperature monitoring module, a car number identification module, and a monitoring center module. The temperature monitoring module is used to monitor the temperature of coal transported by coal cars within a predetermined speed range online. The car number identification module is used to capture relevant information of the coal cars, including the car number. The car number identification module is collaboratively associated with the temperature monitoring module. The monitoring center module is communicatively connected to the temperature monitoring module and the car number identification module through a transmission network and responds based on the received information. The response actions include alarm, early warning, saving, and retrieving information.

[0021] Specifically, an online infrared thermal imager can be installed approximately 6500-6800mm above the ground to monitor the temperature of flammable coal transport vehicles (speeding 5km / h-20km / h), such as in low-speed operation scenarios like loading areas or freight yards. This approach balances monitoring efficiency and data quality, preventing monitoring interruptions due to sudden stops or accelerations. The calibration requirements, optimal installation height and angle, etc., can be calculated and matched by those skilled in the art based on actual usage needs and the performance of the thermal imager.

[0022] In some preferred embodiments, the online temperature monitoring device for railway coal transportation utilizes the aforementioned system, including an online infrared camera, a camera (high-definition camera), and a server (monitoring workstation); the online infrared camera is used to collect thermal imaging data of coal transport vehicles; the camera is used to capture images of the license plates of the coal transport vehicles; the camera and the online infrared camera cover the same vehicle area from the same angle; the server includes a communication module for transmitting data from the online infrared camera and the camera; a storage module suitable for storing thermal imager temperature data, license plate recognition records, and information related to the two; and a data analysis and display module for analyzing high-temperature risk data in conjunction with license plate recognition results and displaying thermal images and license plate recognition results.

[0023] Specifically, the device consists of an online infrared camera and a camera forming the front-end system. The front-end system mainly uses an online infrared thermal imager to collect, encode, store, and upload information, and connects to the vehicle number recognition system at the customer's site. The transmission network is used for communication between the front-end system and the monitoring center. Temperature data and relevant information of coal transport vehicles (truck number, coal type, origin and destination stations, consignor and dispatcher, importing country, and coal temperature) from the front-end system can be uploaded to the monitoring center for easy access and viewing by staff. The monitoring center (server) can remotely monitor the real-time temperature values ​​and trends of coal transport vehicles, and provide timely alarms and warnings.

[0024] With the aforementioned device structure, the online infrared thermal imager measures temperature by detecting the infrared radiation emitted by the target object, eliminating the need for direct contact and avoiding the contact risks inherent in traditional temperature measurement methods. The all-weather system truly achieves 24 / 7 monitoring, ensuring keen visibility at any time and in any environment.

[0025] The system can monitor and record equipment operating temperature values ​​in real time, and display and save the measured temperature values; it can configure the name, alarm value, temperature correction parameters and other attributes of each measuring point individually; the system can record historical monitoring data of multiple devices, support viewing and analyzing equipment operating temperature and trends, and export daily operating temperature data reports; in addition, the entire system has a scalable software and hardware architecture design, which supports subsequent large-scale application expansion and secondary development, and has open interfaces for easy integration and docking.

[0026] In some preferred embodiments, online infrared thermal imagers are deployed near coal transport vehicles for temperature monitoring, providing real-time visual monitoring of equipment temperature. Once an abnormal temperature is detected, an alarm is promptly sent to maintenance personnel, facilitating their response. The system also automatically archives the data for easy tracing and investigation.

[0027] Specifically, the infrared thermal imager is mounted on an adjustable bracket, which includes a mounting plate 2, a support rail 3, a support vertical rod 4, and a mounting plate 5. The mounting plate 2 has corresponding support force, and a fixed insertion rod 23 is configured at the bottom. Multiple sets of fixed insertion rods 23 are arranged at intervals around the central axis of the mounting plate 2. One end of the support rail 3 is rotatably configured at the center of the mounting plate 2, and the other end extends radially along the mounting plate 2 to a predetermined length. The support vertical rod 4 is slidably configured on the support rail 3 along its length direction. The support vertical rod 4 is connected to a locking structure, which is suitable for locking it in position on the support rail 3. The mounting plate 5 slides along the height direction of the support vertical rod 4 via a lifting block 19. The lifting block 19 is connected to a lifting drive. Mounting rotating plates 20 are respectively configured at both ends of the mounting plate 5. The corresponding ends of the mounting rotating plates 20 and the mounting plate 5 are configured for damped rotation. The mounting plate 5 has a rotating groove 22 on the front side of both ends, and is configured in the rotating groove 22 by a damping rotating shaft, so that the mounting plate 20 can rotate around the length of the mounting plate 5. The rear end of the infrared camera body 1 is rotatably configured on the mounting plate 20 by a rotating column 21. The rotating column 21 is configured on the side wall of the mounting plate 20 with damping rotation, so that the infrared camera body 1 can rotate left and right in the horizontal direction.

[0028] In addition, the mounting plate 20 is equipped with a protective cover 6, which is used to protect the infrared thermal imager. The protective cover 6 has an opening on the front side of the infrared camera in the working direction, and a support plate 7 is provided at the bottom of the front side of the protective cover 6. The support plate 7 is suitable for supporting the front end of the infrared camera. Therefore, when the mounting plate 20 rotates, the protective cover 6 and the infrared camera rotate with the mounting plate 20, which can adjust the downward working angle of the infrared camera. When the infrared camera rotates through the rotating column 21, the working angle of the infrared camera can be adjusted left and right. By adjusting downward rotation and left and right rotation, it can be adapted to the recognition working area of ​​the high-definition camera (how to determine the overlap of recognition areas is a prior art and will not be described in this application).

[0029] In this embodiment, preferably, the mounting plate 2 is provided with an annular guide rail 8, and the bottom of the support guide rail 3 is provided with a support shaft 9. The support shaft 9 is slidably adapted to the annular guide rail 8. The support shaft 9 has a first locking hole along its radial direction, and the side wall of the annular guide rail 8 has a second locking hole 10 at a corresponding position. The second locking holes 10 are spaced apart around the central axis of the annular guide rail 8. In this embodiment, the first locking hole and the corresponding second locking hole 10 are coaxially arranged and are both threaded through holes, suitable for locking the threaded rod. After rotating to a suitable position by the support shaft, the threaded rod is screwed into the first locking hole and the second locking hole 10 to lock the position of the support guide rail 3.

[0030] In this embodiment, preferably, the support guide rail 3 is laterally provided with a protective side plate 11 along its length direction. The protective side plate 11 has a limiting groove 12 along its length direction. A locking block 13 is provided on the side of the bottom sliding end of the support vertical rod 4 near the limiting groove 12. Multiple locking screws 15 are provided on the side of the locking block 13 near the limiting groove 12. The multiple locking screws 15 are spaced apart along the length direction of the locking block 13. The locking screws 15 move through the limiting groove 12. Locking bolts 16 with threaded fits are provided on the outside of the protective side plate 11 for the locking screws 15. After the support vertical rod 4 moves to a suitable position along the support guide rail 3, the locking bolts 16 are tightened onto the mounting side plate. The multiple sets of locking bolts 16 are pressed against the mounting side plate to fix the position of the support vertical rod 4.

[0031] It should be noted that the support working surface of the support guide rail 3 is provided with a sliding groove along the length direction. The support vertical rod 4 slides along the sliding groove through the sliding seat 14. The sliding seat 14 is provided with a locking block 13 on the side. The locking screw 15 extends from the inside of the limiting groove 12 to the outside.

[0032] In some preferred embodiments, the lifting drive includes an upper support plate and a lower support plate disposed on the upper and lower ends of the support rod 4. A drive motor 17 is disposed at the bottom of the lower support plate. A support screw 18 is rotatably disposed between the upper and lower support plates. One end of the support screw 18 is fixedly disposed with the output end of the drive motor 17. A lifting block 19 is threadedly disposed with the support screw 18. After the drive motor 17 is started, the output end of the drive motor 17 rotates, causing the support screw 18 to rotate. The rotation of the support screw 18 causes the lifting block 19 to rise and fall, thereby adjusting the working height of the mounting plate 5 and the infrared camera on the mounting plate 5.

[0033] The specific usage is as follows: High-definition cameras and infrared cameras can be installed at both ends of the mounting plate 5 of the adjustment bracket, or an infrared camera can be installed alone to match the recognition operation area of ​​the high-definition camera of the existing vehicle number recognition system. In the initial state, the mounting plate 5 is located at a low position. The mounting plate 20 and the rotating column 21 can be rotated to adjust the top and left and right angles of the infrared camera and the high-definition camera at both ends of the mounting plate 5, respectively. Then, the drive motor 17 is started to adjust the working height of the mounting plate 5. At the same time, the support rail 3 and the support rod 4 can be rotated as a whole to make the infrared camera and the high-definition camera perform corresponding monitoring and identification operations in a suitable position.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In summary, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention. Each component of this application can be driven by a corresponding external motor; this is prior art and will not be elaborated upon here.
