Description

Technical Field

[0001] This utility model relates to the technical field of railway traffic safety supervision, and in particular to a railway locomotive traffic safety supervision device. Background Technology

[0002] In the complex environment of railway locomotive driving, traffic safety is always the primary concern. To ensure the safety of passengers, goods, and the locomotive itself, strict supervision of driver behavior is particularly important. Currently, most railway locomotives rely on camera systems for traffic safety monitoring, which record video data from the cab throughout the entire process, providing important evidence for post-event analysis. However, while this record-based monitoring method can reconstruct the driving process, it is clearly insufficient in preventing and correcting improper driver behavior in real time.

[0003] Specifically, during driving, especially in scenarios requiring frequent adjustments to speed and braking, drivers primarily rely on their personal driving experience and judgment of the vehicle's speedometer display. Under complex driving conditions such as high-speed driving, inclement weather, low visibility, or sudden emergencies, this reliance often leads to misjudgments or slow reactions, thereby increasing driving risks. More importantly, existing monitoring devices have relatively limited functions, mainly focusing on "recording" and lacking intelligent analysis and early warning capabilities. They cannot assess the rationality of the driver's actions in real time, nor can they provide necessary assistance or warnings to the driver at critical moments to correct inappropriate behavior or avoid potential dangers. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a railway locomotive operation safety monitoring device. This device not only significantly improves the accuracy and reaction speed of the driver's speed control in complex driving environments, but also effectively reduces the safety risks caused by human misjudgment and negligence through intelligent assistance and warning methods, providing a more solid technical guarantee for the operation safety of railway locomotives.

[0006] To achieve the above objectives, this utility model proposes a railway locomotive operation safety monitoring device, including a speed dial and a speed monitoring device. The speed dial is rotatably connected to the mounting surface of the driver's cab control panel. The speed monitoring device includes a frame, a camera device, an information processing device, a vibration warning device, a light indicator device, and an encoder speed detection device. The frame is snap-fitted to the mounting surface. The camera device and the light indicator device are respectively fixedly connected to the top of the frame. The information processing device and the vibration warning device are respectively fixedly connected to the inner wall of the frame. The encoder speed detection device is located at the bottom of the frame and connected to the speed dial. The information processing device achieves bidirectional data transmission with an external host computer via wireless communication, including uploading data and receiving control commands. The information processing device is seamlessly connected to the camera device, the vibration warning device, the light indicator device, and the encoder speed detection device via a high-efficiency control bus, ensuring real-time data exchange and accurate execution of control commands.

One end of the cross-shaped connecting rod penetrates into the arc-shaped mounting groove and is vertically slidably connected to the inner wall of the cross-shaped connecting cylinder. The output end of the AB-phase encoder is connected to the input end of the processor.

[0009] Specifically, the vibration warning device also includes a vibration isolation system, which is designed to significantly reduce the interference caused by vibrations generated during the operation of the vibration warning device to the encoder speed detection device, thereby ensuring the accuracy and stability of the encoder speed detection device during operation.

[0010] Specifically, the vibration isolation system includes a direct vibration isolation device and an indirect vibration isolation device. The direct vibration isolation device is located at the vibration warning device and its function is to directly isolate the vibration force at the vibration source, thereby significantly reducing the vibration intensity transmitted to the arc-shaped frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This device has a reasonable structure.

Subsequently, it precisely controls the LED indicator light of the corresponding speed gear in the light indicator device to illuminate, providing the driver with intuitive and clear gear shifting prompts. This effectively guides the driver to adjust the vehicle speed in a timely manner according to road conditions and dispatch requirements, thereby ensuring the safety and efficiency of the driving process. When the encoder speed detection device detects that the driver has failed to make the corresponding adjustment according to the speed command within a reasonable time, the system will immediately activate the warning mechanism, providing a non-intrusive reminder to the driver in the form of vibration. This immediate feedback can quickly attract the driver's attention and prompt them to take immediate action. At the same time, to ensure full traceability, this device is also equipped with a high-definition camera recording function, which automatically records the driver's reaction and vehicle status throughout the process, providing strong evidence for post-event analysis.

[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0032] The following description, in conjunction with the accompanying drawings, describes a railway locomotive traffic safety monitoring device according to an embodiment of the present invention.

[0033] like Figures 1-6As shown in the figure, a railway locomotive operation safety monitoring device according to an embodiment of the present invention includes a speed dial 1 and a speed monitoring device 2. The speed dial 1 is rotatably connected to the surface of the mounting base 11 of the cab control panel 10. The speed monitoring device 2 includes a frame 21, a camera device 22, an information processing device 24, a vibration warning device 25, a light indicator device 23, and an encoder speed detection device 26. The frame 21 is snapped and fixed to the surface of the mounting base 11. The camera device 22 and the light indicator device 23 are respectively fixedly connected to the top of the frame 21. The information processing device 24 and the vibration warning device 25 are respectively fixedly connected to the inner wall of the frame 21. The encoder speed detection device 26 is located at the bottom of the frame 21 and connected to the speed dial 1. The information processing device 24 realizes bidirectional data transmission with an external host computer through wireless communication, including uploading data and receiving control commands. The information processing device 24 is seamlessly connected to the camera device 22, the vibration warning device 25, the light indicator device 23, and the encoder speed detection device 26 through a high-efficiency control bus to ensure real-time data exchange and accurate execution of control commands.

[0034] In practical use, the information processing device 24 communicates with an external host computer in real time to receive and parse vehicle speed commands. It then precisely controls the LED 232 of the corresponding speed gear in the light indicator device 23 to illuminate, providing the driver with intuitive and clear gear shifting prompts. This effectively guides the driver to adjust the vehicle speed in a timely manner according to road conditions and dispatch requirements, thereby ensuring safety and efficiency during driving. The driver then rotates the speed dial 1 according to the light indicator within a set time to adjust the gear. When the encoder speed detection device 26 detects that the driver has failed to make the corresponding adjustment according to the speed command within a reasonable time (i.e., rotate the speed dial 1), the information processing device 24 immediately controls the vibration warning device 25 to operate, providing a non-intrusive reminder to the driver through vibration. This immediate feedback quickly attracts the driver's attention, prompting them to take immediate action. Simultaneously, to ensure full traceability, the device also controls the camera device 22 to automatically record the driver's reaction and vehicle status throughout the process, providing strong evidence for post-event analysis.

[0035] In one embodiment of this utility model, such as Figures 1-4As shown, the frame 21 includes a portal frame 211 and an arc-shaped frame 212. The portal frame 211 spans across the top of the mounting base 11, and the arc-shaped frame 212 is integrally formed on the surface of the portal frame 211 and located on the outside of the mounting base 11. The portal frame 211 and the arc-shaped frame 212 are respectively snapped and fixed to the surface of the mounting base 11 by elastic clips 100. The camera device 22 is a camera. The light indicator device 23 includes a lamp holder 231 and LED lights 232. There are 17 sets of LED lights 232. The 17 sets of LED lights 232 are sequentially fixedly connected to the surface of the lamp holder 231 and are respectively connected to the information processing device 24. The information processing device 24 includes a mounting plate 241, a processor 242, a wireless communication module 243, a lighting control module 244, a timing module 245, a positioning module 246, an image processing module 247, and a power module 248. The mounting plate 241 is fixedly connected to the inner wall of the portal frame 211. The processor 242, wireless communication module 243, lighting control module 244, timing module 245, positioning module 246, and image processing module 247 are sequentially fixedly connected to the top of the mounting plate 241 along the X-axis. The power module 248 is fixedly connected to the inner wall of the portal frame 211 and is located on one side of the bottom of the mounting plate 241.The power supply module 248 provides a stable power supply for the entire system. It connects to the processor 242, wireless communication module 243, lighting control module 244, timing module 245, positioning module 246, image processing module 247, vibration warning device 25, and encoder speed detection device 26 via a power cord or power interface. The processor 242 is the core control unit of the entire system, responsible for parsing instructions sent from the external host computer and controlling other modules to perform corresponding operations based on these instructions. The processor 242 communicates with the wireless communication module 243, lighting control module 244, timing module 245, positioning module 246, image processing module 247, vibration warning device 25, and encoder speed detection device 26 via a data bus to receive and send instructions and data. The wireless communication module 243 is responsible for wireless communication with the external host computer. It establishes a connection with the external host computer via wireless signals and transmits instructions and data. Data received by the wireless communication module 243 is transmitted to the processor 242 for processing, and the processed results are then transmitted back to the processor 242. 3. The lighting control module 244 is connected to the lighting indicator device 23 and is used to control the LED lights 232 in the lighting indicator device 23 to turn on, turn off, adjust brightness, or change color. The timing module 245 is used to provide timing functions, such as setting operation time and timing. The timing module 245 provides timing signals to the processor 242. The processor 242 controls the operation of other modules according to the timing signals, such as manually adjusting the operation time of the speed dial 1, the duration of the LED lights 232, and the trigger time of the vibration warning device 25. The positioning module 246 is used to provide the precise position, speed, and direction data of the current vehicle. The positioning module 246 sends the data to the processor 242. The processor 242 compares the data with the set data sent by the external host computer to determine whether the current vehicle speed meets the standard. The image processing module 247 is connected to the camera device 22 through the data interface. The image processing module 247 is responsible for processing the image data captured by the camera device 22. The processed image data is sent to the external host computer through the wireless communication module 243. The vibration warning device 25 is a vibration motor.The encoder speed detection device 26 includes an arc-shaped rack 261, a gear 262, a cylindrical slide 263, an AB phase encoder 264, a cross-shaped connecting cylinder 265, and a cross-shaped connecting rod 266. The arc-shaped frame 212 has an arc-shaped mounting groove at its bottom. The arc-shaped rack 261 is fixedly connected to the inner wall of the upper end of the arc-shaped mounting groove. The cylindrical slide 263 is horizontally slidably connected to the inner wall of the lower end of the arc-shaped mounting groove. The gear 262 is rotatably connected to the top of the cylindrical slide 263 and meshes with the teeth on the surface of the arc-shaped rack 261. The B-phase encoder 264 is fixedly connected to the inner wall of the cylindrical slide 263 and to one end of the central shaft of the gear 262. The cross-shaped connecting cylinder 265 is fixedly connected to the bottom of the cylindrical slide 263. The cross-shaped connecting rod 266 is threaded to the top of the speed dial 1 and corresponds to the position of the cross-shaped connecting cylinder 265. One end of the cross-shaped connecting rod 266 passes through the arc-shaped mounting groove and slides vertically against the inner wall of the cross-shaped connecting cylinder 265. The output end of the AB-phase encoder 264 is connected to the input end of the processor 242.

[0036] It should be noted that the structure, connection and control relationship of the camera, LED light 232, processor 242, wireless communication module 243, light control module 244, timing module 245, positioning module 246, image processing module 247, power supply module 248, vibration motor and AB phase encoder 264 described in this embodiment are all existing technologies, and therefore will not be described in detail here.

[0037] It should also be noted that the information processing device 24 also includes a scoring module (not shown in the figure). The processor 242 communicates with the scoring module via a data bus to receive and send instructions and data. The scoring module is used to actively track and accurately record each activation of the vibration warning device 25, and uses this operational data to quantitatively evaluate the driver's driving behavior. Subsequently, through the efficient and stable wireless communication module 243, these scores are transmitted instantly and securely to an external host computer for management personnel, the driver, or relevant stakeholders to view and analyze. Specifically, the scoring module will assign an objective and fair score to each driver's driving performance based on the frequency of vibration warnings and using a complex algorithm model.

[0038] Understandably, the 17 LED lights 232 correspond to the 17 speed settings (0-16) on the speed dial 1.

[0039] Specifically, the structure and connection relationship of the frame 21, camera device 22, information processing device 24, vibration warning device 25, light indicator device 23, and encoder speed detection device 26 are further explained. The portal frame 211 in the frame 21 facilitates the installation of the camera. The arc-shaped frame 212 is adapted to the external dimensions of the speed dial 1, not affecting the use of the speed dial 1, and also facilitating the encoder speed detection device 26 to detect the speed dial 1. The encoder speed detection device 26 operates as follows: when the speed dial 1 shifts gears, it synchronously drives the cross-connecting rod 266 to move. The movement of the cross-connecting rod 266 synchronously drives the cross-connecting cylinder 265, the cylindrical slide 263, the AB phase encoder 264, and the gear 262 to move within the arc-shaped mounting groove. As the gear 262 moves smoothly along the preset trajectory, it seamlessly meshes with the precisely machined teeth on the surface of the arc-shaped rack 261. This dynamic interaction causes the gear 262 to start rotating immediately and synchronously. The AB phase encoder 264 accurately tracks and records the number of rotations of the gear 262 in real time, and then seamlessly transmits this key data information to the processor 242. After receiving the data, the processor 242 quickly and efficiently processes it. By analyzing this data, it accurately determines the specific position of the cylindrical slide 263 in the arc-shaped mounting groove. Subsequently, the processor 242 accurately compares this position information with the position of the LED light 232 of the preset gear, thereby efficiently verifying whether the current gear on the speed dial 1 matches the gear required by the vehicle speed command.

[0040] In one embodiment of this utility model, such as Figures 5-6 As shown, the vibration warning device 25 also includes a vibration isolation system 3. The vibration isolation system 3 is designed to significantly reduce the interference caused by the vibration generated during the operation of the vibration warning device 25 to the encoder speed detection device 26, and to ensure the accuracy and stability of the encoder speed detection device 26 during operation.

[0041] Specifically, by setting up the vibration isolation system 3 to reduce the vibration generated during the operation of the vibration warning device 25, the accuracy and stability of the encoder speed detection device 26 during operation are improved, resulting in good performance.

[0042] In one embodiment of this utility model, such as Figures 5-6 As shown, the vibration isolation system 3 includes a direct vibration isolation device 31 and an indirect vibration isolation device 32. The direct vibration isolation device 31 is located at the vibration warning device 25, and its function is to directly isolate the vibration force at the vibration source, thereby significantly reducing the vibration intensity transmitted to the arc frame 212. The indirect vibration isolation device 32 is located at the encoder speed detection device 26, and by providing an effective protection mechanism, it significantly reduces the vibration force transmitted from the arc frame 212 to the encoder speed detection device 26, further ensuring the accuracy and stability of the encoder speed detection device 26 during operation.

[0043] Specifically, by setting vibration isolation devices at the vibration source and the end position respectively, the interference caused by vibration force to the encoder speed detection device 26 can be effectively reduced, ensuring the accuracy and stability of the encoder speed detection device 26 during operation, and the effect is good.

[0044] In one embodiment of this utility model, such as Figures 5-6 As shown, the direct vibration isolation device 31 includes a rubber vibration isolation seat 311, a mounting box 312, and a transparent material box 313. The rubber vibration isolation seat 311 is fixedly connected to the inner wall of the arc-shaped frame 212. An eccentric mounting groove is provided on the top of the rubber vibration isolation seat 311. The mounting box 312 is fixedly connected to the inner wall of the eccentric mounting groove. A vibration warning device 25 is fixedly connected to the inner wall of the mounting box 312. The transparent material box 313 is bolted to the top of the arc-shaped frame 212. A rubber vibration isolation pad 314 is provided between the bottom of the transparent material box 313 and the top of the arc-shaped frame 212. A rigid transmission part 315 is fixedly connected to the bottom of the transparent material box 313. One end of the guide section 315 penetrates into the interior of the mounting box 312 and is fixedly connected to the surface of the vibration warning device 25; the transparent material box 313 contains a special liquid that changes color when subjected to vibration and shakes; the indirect vibration isolation device 32 includes a U-shaped frame 321 and a U-shaped vibration isolation pad 322, wherein the U-shaped frame 321 is fixedly connected to the inner wall of the arc-shaped mounting groove, the U-shaped vibration isolation pad 322 is disposed between the outer surface of the U-shaped frame 321 and the inner wall of the arc-shaped mounting groove, the arc-shaped rack 261 is fixedly connected to the inner wall of the upper end of the U-shaped frame 321, and the columnar slide block 263 is horizontally slidably connected to the inner wall of the lower end of the U-shaped frame 321.

[0045] Understandably, the mounting box 312 is located at the end of the rubber vibration isolation seat 311 that is away from the encoder speed detection device 26.

[0046] Specifically, the structure and connection relationship of the direct vibration isolation device 31 and the indirect vibration isolation device 32 will be further explained. During use, since the mounting box 312 is located at the end of the rubber vibration isolation seat 311 away from the encoder speed detection device 26, when the vibration warning device 25 is running, the rubber vibration isolation seat 311 will not significantly weaken the vibration force towards the inner wall of the arc-shaped frame 212, allowing the driver to perceive the vibration. However, it will significantly weaken the vibration force towards the encoder speed detection device 26, reducing interference to the encoder speed detection device 26. Since the vibration force still acts on the arc-shaped frame 212, in order to further reduce the interference of the vibration force on the arc-shaped frame 212 on the encoder speed detection device 26, a protective mechanism is installed on the inner wall of the arc-shaped mounting groove. This protective mechanism is the indirect vibration isolation device 32, consisting of U... The device consists of a U-shaped frame 321 and a U-shaped vibration isolation pad 322. The U-shaped frame 321 is used to replace the arc-shaped mounting groove for installing the indirect vibration isolation device 32. The U-shaped vibration isolation pad 322 is used to weaken the vibration force on the arc-shaped frame 212, further ensuring the accuracy and stability of the encoder speed detection device 26 during operation. Since the rubber vibration isolation seat 311 reduces some vibration effect, a transparent material box 313 is also provided to ensure the warning effect. The transparent material box 313 contains a special liquid and is connected to the vibration warning device 25 through a rigid transmission part 315. When the vibration warning device 25 is running, the vibration force is synchronously transmitted to the transparent material box 313 through the rigid transmission part 315. Affected by the vibration force, the liquid inside changes color when it shakes. The color change combined with the vibration reminds the driver to pay attention, and the effect is good.

[0047] In one embodiment of this utility model, such as Figure 5 As shown, the special liquid inside the transparent container 313 is a carefully prepared mixture of indigo carmine, sodium hydroxide, and glucose in a specific ratio.

[0048] It should be noted that the glucose described in this embodiment, as a reducing agent, will be gradually consumed. When the glucose is exhausted, the solution will no longer be able to reduce the oxidized indigo carmine, thus causing the color change phenomenon to disappear. To ensure the color change, a glucose storage box (not shown in the figure) needs to be installed on the top of the transparent tank 313. The drain port of the glucose storage box is inserted into the transparent tank 313. After the transparent tank 313 is vibrated, some of the vibration force will be transmitted to the glucose storage box. Affected by the vibration force, the glucose at the drain port will automatically drip into the transparent tank 313 under the action of the vibration force. The amount of glucose dripping is affected by the vibration time of the vibration warning device 25.

[0049] Specifically, when a mixed solution containing indigo carmine, sodium hydroxide, and glucose is left to stand, the solution may appear red, yellow, or other colors (depending on the initial redox state). After shaking the solution, the color may turn green due to the oxidation of oxygen. After standing for a period of time, the reduction of glucose will cause the solution color to change again, returning to red, yellow, or another color. The color change, combined with vibration, serves to alert drivers.

[0050] In summary, the railway locomotive operation safety monitoring device of this utility model not only significantly improves the accuracy and reaction speed of the driver's speed control in complex driving environments, but also effectively reduces the safety risks caused by human misjudgment and negligence through intelligent assistance and warning methods, providing a more solid technical guarantee for the operation safety of railway locomotives.
