Description

Technical Field

[0001] This invention relates to the field of parking management technology for internal combustion locomotives, and specifically to a wireless remote control parking management system for internal combustion locomotives. Background Technology

[0002] With the booming development of urban rail transit and the increasing demand for freight logistics in my country, diesel locomotives are being used more and more frequently. Diesel locomotives serve as a bridge for logistics transportation between cities, transporting goods between them. Due to the importance of diesel locomotive transportation, operators regularly inspect and maintain the tracks on which they travel. These operators work within a two-meter radius of the tracks, and the locomotive travels on these tracks during their work, creating unique working characteristics that result in high risks and significant operational difficulties.

[0003] When workers are working on the tracks of a diesel locomotive and receive a signal that the locomotive is about to enter the area, they will stop their work and briefly evacuate the area to avoid personal injury. However, in actual operations, when the working area on the locomotive tracks is large and the work span is long, it is difficult for workers to evacuate the area in time, or they may be too close to the tracks. If this happens when the locomotive passes through the work area, an accident may occur. To prevent such accidents, supervisors will press a remote control to send a braking command to the locomotive, and the locomotive's braking system will brake upon receiving the command. Currently, supervisors generally monitor whether workers have evacuated the danger zone through visual inspection. However, this method is insufficient to detect dangerous behavior in a timely manner, especially when the work span is large, again contributing to accidents.

[0004] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a wireless remote control parking management system for internal combustion locomotives, which solves the above-mentioned technical problems. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a wireless remote control parking management system for diesel locomotives. The system uses a monitoring module to monitor operators before the diesel locomotive enters the work area, and an analysis module to eliminate potential safety hazards. With timely braking of the diesel locomotive, accidents can be avoided.

[0006] The present invention discloses a wireless remote control parking management system for internal combustion locomotives, comprising a monitoring terminal, a management terminal, and a monitoring terminal; the monitoring terminal, the management terminal, and the monitoring terminal are connected via a network for data transmission; the monitoring terminal transmits monitoring data to the management terminal for safety analysis, and then the monitoring terminal controls the sending of braking commands.

[0007] The monitoring terminal includes a first transmission unit, a receiving module, and a monitoring module; the receiving module is used to receive data transmitted by the first transmission unit; the monitoring module is used to monitor the operators and transmit the monitored data to the management terminal through the first transmission unit.

[0008] The management terminal includes a second transmission unit and an analysis module; the second transmission unit can transmit the received monitoring data to the analysis module for analysis; the analysis module transmits the analysis results to the monitoring terminal through the second transmission unit.

[0009] The monitoring terminal includes a third transmission unit and a monitoring module; the third transmission unit can receive data analyzed by the analysis module and transmit it to the monitoring module for reception; the monitoring personnel control the sending of braking commands based on the data received by the monitoring module.

[0010] Preferably, the monitoring module includes an image acquisition unit; the image acquisition unit uses a camera device as a carrier; the image acquisition unit is installed on the front side of the worker's helmet; the image acquisition unit is used to acquire work image data from the front of the worker; the analysis module can determine the worker's work position based on the data monitored by the monitoring module.

[0011] Preferably, the analysis module includes an analysis unit and a modeling unit; the modeling unit is capable of establishing a digital stereo model based on image data; the analysis unit measures the position of elements around the track based on the digital stereo model.

[0012] Preferably, the elements include workers, tools, and materials; the analysis module further includes an extraction unit and an input unit; the extraction unit can extract the outline of the elements and measure the position of the elements on the track; the input unit is used to pre-input the outline of the elements.

[0013] Preferably, the modeling unit enlarges the digital 3D model based on the standard size of the elements; the analysis unit performs analysis based on the scaled-up digital 3D model.

[0014] Preferably, the extraction unit can also extract the contour lines of the tracks in the digital 3D model; the analysis unit can perform analysis based on the contour line results extracted by the extraction unit.

[0015] Preferably, the monitoring module further includes a sound acquisition unit; the sound acquisition unit is used to collect the sound data of the operators; the sound acquisition unit transmits the collected sound data to the analysis module for analysis through a first transmission unit and a second transmission unit; the extraction unit in the analysis module can extract the keywords set in the audio data and have them analyzed by the analysis unit; the input unit can input the keywords that the sound extraction unit needs to extract.

[0016] Preferably, the analysis module further includes a comparison unit; the comparison unit compares the digital stereoscopic models established in the previous and next frames; the analysis unit forms a motion trend based on the elements compared by the comparison unit and derives the analysis results.

[0017] Preferably, the monitoring terminal is interconnected with the braking system; the braking system includes a brake controller, a microcontroller, a power supply, a short-range wireless module, a remote controller, and an electrical control system; the electrical control system is used to connect the power supply, the short-range wireless module, and the microcontroller to the braking system; the short-range wireless module is used to detect remote braking commands triggered by the remote controller; the remote controller is used to send braking commands; the power supply is used to power the entire system; the microcontroller is used to detect braking commands and record the number of braking operations; the braking power supply unit is used to detect braking signals and turn on the braking power; in use, the monitoring personnel at the monitoring terminal, based on the analysis results from the analysis module, selectively press the remote controller after receiving the data from the monitoring module. When the remote controller is pressed, the braking system will brake the internal combustion locomotive.

[0018] The stopping control method in a diesel locomotive includes the following steps: First, power the entire system and pair the short-range wireless module and remote control one-to-one; Second, the entire circuit is in standby mode when the external remote control presses the brake button; Third, activate the brake power supply circuit relay, changing the relay state from normally open to closed, allowing power to be supplied to the braking system; Fourth, when the relay is closed, the microcontroller pin detects a low level and records the data; Fifth, after the braking action is completed, the relay needs to be manually reset to cut off the brake power supply and end the braking action.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention monitors the workers before the diesel locomotive enters the work area using a monitoring module, and eliminates potential safety hazards through analysis using an analysis module. With timely braking of the diesel locomotive, accidents can be avoided.

[0021] 2. Because the image acquisition unit acquires images of the work tool from a distance, the size of the work tool in the image data acquired by the image acquisition unit is inevitably small. However, after the work tool is enlarged to its actual size by the modeling unit, the analysis unit can more accurately measure the distance of each element from the track, thereby determining whether each element is far from the track and within the safe area. By measuring the distance between each element and the track in three-dimensional space, misjudgments caused by visual misalignment are avoided. Through three-dimensional measurement, misjudgments are avoided, making the analysis results of the analysis unit more accurate.

[0022] 3. In this invention, when the sound acquisition unit extracts keywords, the image data acquired by the image acquisition unit at the same location as the sound acquisition unit is preferentially popped up. The pop-up method can be that the digital stereo model at the location where the keyword is extracted is called up for analysis, thereby enabling the analysis unit to perform priority analysis on the digital stereo model at that location, which greatly improves the timeliness of safety hazard detection, improves the efficiency of safety hazard detection, and avoids the occurrence of accidents.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figure 1-7 As shown, the present invention includes the following embodiments:

[0033] Example 1: A wireless remote control parking management system for internal combustion locomotives includes a monitoring terminal, a management terminal, and a monitoring terminal; the monitoring terminal, management terminal, and monitoring terminal are connected via a network for data transmission; the monitoring terminal transmits monitoring data to the management terminal for safety analysis, and then the monitoring terminal controls the sending of braking commands.

[0034] The monitoring terminal includes a first transmission unit, a receiving module, and a monitoring module; the receiving module is used to receive data transmitted by the first transmission unit; the monitoring module is used to monitor the operators and transmit the monitored data to the management terminal through the first transmission unit.

[0035] The management terminal includes a second transmission unit and an analysis module; the second transmission unit can transmit the received monitoring data to the analysis module for analysis; the analysis module transmits the analysis results to the monitoring terminal through the second transmission unit.

[0036] The monitoring terminal includes a third transmission unit and a monitoring module; the third transmission unit can receive data analyzed by the analysis module and transmit it to the monitoring module for reception; the monitoring personnel control the sending of braking commands based on the data received by the monitoring module.

[0037] In this embodiment, the monitoring module includes an image acquisition unit; the image acquisition unit uses a camera device as a carrier; the image acquisition unit is installed on the front side of the worker's helmet; the image acquisition unit is used to acquire work image data from the front of the worker; the analysis module can determine the worker's work position based on the data monitored by the monitoring module.

[0038] In practice, existing supervisors typically monitor whether workers have evacuated from dangerous areas through visual inspections. However, when the work spans a large area, supervisors may find it difficult to detect dangerous behaviors by workers in a timely manner, which can also lead to accidents.

[0039] Therefore, before commencing operations, workers must wear safety helmets. The front of the safety helmet is embedded with an image acquisition unit. While wearing the helmet, workers operate on the track. When a diesel locomotive is about to enter the work area, it transmits a message to the third transmission unit in the monitoring terminal. The third transmission unit then transmits the information to the monitoring module. Upon receiving confirmation of the locomotive's entry into the work area, the monitoring personnel at the monitoring terminal transmit the locomotive's information through the third transmission unit to the second transmission unit, which then transmits it to the first transmission unit. Finally, the first transmission unit transmits the information about the locomotive's entry into the work area to the receiving module. The receiving module can read the information via voice broadcast. This alerts workers to move away from the track. When the receiving module detects the diesel locomotive entering the work area, the monitoring module is triggered. The image acquisition unit within the monitoring module then captures and records images of the environment in front of the workers. The monitoring module transmits the data collected by the image acquisition unit to the second transmission unit via the first transmission unit. The second transmission unit then transmits the data to the analysis module. The analysis module uses the track in the image data as a reference point and defines danger zones (e.g., two meters) on both sides of the track. If the analysis module indicates that a worker is within the danger zone, it indicates a safety hazard. If the analysis module determines that a worker is outside the danger zone, it indicates that there is no safety risk. This comprehensive approach eliminates all potential safety hazards. By analyzing image data through the analysis module, potential safety risks can be quickly identified. More importantly, the monitoring module includes multiple image acquisition units, matching the number of workers. Each unit can capture images of other workers in front of them, providing multi-angle image data from various perspectives, achieving comprehensive monitoring without blind spots. The mutual monitoring process exposes and monitors the working environment of all workers, significantly improving safety. After analyzing the image data collected by the acquisition units, the analysis module exports the results. The analysis results are transmitted to the third transmission unit via the second transmission unit, and finally transmitted to the monitoring module by the third transmission unit. After obtaining the analysis results from the analysis module through the monitoring module, if there is a potential safety hazard, the monitoring personnel will press the remote control. The remote control will then issue a braking command to the braking system of the diesel locomotive, causing the locomotive to brake and avoid an accident. After the diesel locomotive has passed through the work area, the on-board unit in the locomotive will transmit information that the locomotive has completely left the work area to the receiving module via the third, second, and first transmission units. Once the receiving module receives the message that the locomotive has left, it will be captured by the monitoring module, and the image acquisition unit will stop image acquisition.

[0040] This invention monitors the workers before the diesel locomotive enters the work area using a monitoring module, and eliminates potential safety hazards through analysis using an analysis module. With timely braking of the diesel locomotive, accidents can be avoided.

[0041] Example 2 differs from Example 1 in that:

[0042] The analysis module includes an analysis unit and a modeling unit; the modeling unit can build a digital stereo model based on image data; the analysis unit measures the position of elements around the track based on the digital stereo model.

[0043] In this embodiment, the elements include workers, tools, and materials; the analysis module further includes an extraction unit and an input unit; the extraction unit can extract the outline of the elements and measure the position of the elements on the track; the input unit is used to pre-input the outline of the elements.

[0044] In this embodiment, the modeling unit enlarges the digital 3D model based on the standard size of the elements; the analysis unit performs analysis based on the scaled-up digital 3D model.

[0045] In this embodiment, the extraction unit can also extract the contour lines of the tracks in the digital 3D model; the analysis unit can perform analysis based on the contour line results extracted by the extraction unit.

[0046] Before the system is put into use, the input unit in the analysis module of the management terminal will input the outlines of the operators, tools, and materials. Specifically, the outlines of the operators, tools, and materials can be digitized by scanning and named individually. After the image acquisition unit is triggered, the data acquired by the image acquisition unit is transmitted along the first transmission unit and the second transmission unit to the modeling unit in the analysis module. The modeling unit will build a spatial digital 3D model based on the image data from multiple angles. Subsequently, the extraction unit will extract the elements from the digital 3D model. The extraction unit then inputs the operators, tools, and materials into the input unit. After outlining the data, the training process is completed, allowing for the extraction of elements from the digital stereo model. These elements include workers, tools, and materials. Once extracted, the outline dimensions of each element are obtained. Using one element as a reference—for example, a tool whose actual length from view A is 1.5 meters, while its length displayed in the digital stereo model from view A is 0.8 meters—the modeling unit enlarges the 0.8-meter tool to a standard 1.5-meter size to ensure the accuracy of the analysis unit's assessment of the distances from each element to the track. This is because the image acquisition unit operates from a distance from the tool. Image acquisition is performed, so the size of the work tools displayed in the image data acquired by the image acquisition unit is relatively small. However, after the work tools are enlarged to their actual size by the modeling unit, the analysis unit can more accurately measure the distance of each element from the track, thereby determining whether each element is far from the track and within the safe zone. By measuring the distance between each element and the track in three-dimensional space, misjudgments caused by visual misalignment are avoided. For example, from the perspective of someone behind a worker, the worker may appear to be obstructing the view of the track, even if the worker is actually far from the track and within the safe zone. This embodiment avoids misjudgments by measuring in three dimensions, thus improving the accuracy of the analysis. The unit analysis results are more accurate. While extracting elements from the digital 3D model, the extraction unit also extracts the track outline. If there are obstructions on the outline, such as stones, the track outline cannot be completely extracted. In this case, the analysis unit will determine that there are foreign objects on the track outline or that the track is broken, and will output a result indicating a safety hazard. Conversely, if the extraction unit extracts a complete track outline, the analysis unit will output a result indicating that the track is currently safe. The analysis module will transmit the analysis results to the monitoring terminal through the second transmission unit, and the monitoring personnel at the monitoring terminal will then proceed with the next step.

[0047] Example 3 differs from Example 2 in that:

[0048] The monitoring module also includes a sound acquisition unit; the sound acquisition unit is used to collect the sound data of the operators; the sound acquisition unit transmits the collected sound data to the analysis module for analysis through a first transmission unit and a second transmission unit; the extraction unit in the analysis module can extract keywords set in the audio data and have them analyzed by the analysis unit; the input unit can input the keywords that the sound extraction unit needs to extract;

[0049] When in use, the sound acquisition unit is activated simultaneously when the image acquisition unit is activated. The sound acquisition unit and the image acquisition unit are installed in the same location. The sound acquisition unit can collect sounds around the workers. The sound acquisition unit transmits the sound data to the extraction unit in the analysis module through the first transmission unit and the second transmission unit. The input unit will pre-enter the keywords that the extraction unit needs to extract. The extraction unit will extract keywords from the sound data collected by the sound acquisition unit according to the keywords entered by the input unit, such as "walk fast", "stop", "danger", etc. The keywords are determined according to the workers' word usage habits. When the sound acquisition unit extracts keywords, the image data collected by the image acquisition unit in the same location as the sound acquisition unit is prioritized. The way it is prioritized is by calling up the digital stereo model at the location where the keyword was extracted for analysis. This allows the analysis unit to prioritize the analysis of the digital stereo model at that location, thereby greatly improving the timeliness and efficiency of safety hazard detection and preventing accidents from occurring.

[0050] Example 4 differs from Example 2 in that:

[0051] The analysis module also includes a comparison unit; the comparison unit compares the digital stereoscopic models established in the previous and next frames; the analysis unit forms a motion trend based on the elements compared by the comparison unit and derives the analysis results;

[0052] In use, the digital stereo model is built by the modeling unit within the same frame. This means that the modeling unit will generate multiple digital stereo models at intervals. The comparison unit will compare the elements in the digital stereo models before and after the modeling unit to obtain the movement trend of each element. For example, if the distance between the worker or the work tool and the track in the later frame is greater than the distance between the worker and the track in the earlier frame, it means that the worker or the work tool is away from the track. Conversely, if the distance is less than the distance between the worker or the work tool and the track, it means that the worker or the work tool is closer to the track. Based on the comparison results of the comparison unit, the analysis unit will issue an early warning for the situation of being close to the track, thereby predicting potential safety hazards and further improving the timeliness of safety hazard detection.

[0053] Example 5:

[0054] The monitoring terminal is interconnected with the braking system. The braking system includes a brake controller, a microcontroller, a power supply, a short-range wireless module, a remote controller, and an electrical control system. The electrical control system connects the power supply, the short-range wireless module, and the microcontroller to the braking system. The short-range wireless module detects remote braking commands triggered by the remote controller. The remote controller sends braking commands. The power supply powers the entire system. The microcontroller detects braking commands and records the number of braking operations. The braking power supply unit detects braking signals and activates the braking power. In use, the monitoring personnel at the monitoring terminal, based on the analysis results from the analysis module, selectively press the remote controller after receiving the data. When the remote controller is pressed, the braking system applies brakes to the internal combustion locomotive.

[0055] The shutdown control method in a diesel locomotive includes the following steps: First, power the entire system and pair the short-range wireless module and remote control one-to-one; Second, the entire circuit is in standby mode when the external remote control presses the brake button; Third, activate the brake power supply circuit relay, changing the relay state from normally open to closed, allowing power to be supplied to the braking system; Fourth, when the relay is closed, the microcontroller pin detects a low level and records the data; Fifth, after the braking action is completed, the relay needs to be manually reset to cut off the brake power supply and end the braking action.

[0056] like Figure 2 As shown, the remote control contains a short-range wireless transmitter module, which can be paired one-to-one with the receiver module. When the remote control presses a button, the transmitter module is activated, sending commands to the receiver module; for example... Figure 3 Here is the schematic diagram of the short-range wireless receiver module: When the receiver module receives a command, it will open the relay at the back end, changing the relay state from normally open to normally closed, thereby supplying power to the braking system at the back end; at the same time, the microcontroller will record the corresponding braking data. Figure 5 The system power supply circuit schematic diagram consists of two parts: the first part supplies power to the wireless module and the brake power supply relay circuit, and the second part provides power to the entire microcontroller system after voltage reduction.
