At present, the early warning technology for safe train operation has made certain progress at home and abroad. Common technical means include track status detection, obstacle identification, and meteorological condition monitoring. These technologies use various sensors and data processing systems to monitor the surrounding environment of the train in real time, detect potential risks in a timely manner, and thus improve driving safety. However, the existing early warning technology still has many limitations, especially in complex terrain and extreme weather conditions, the reliability and accuracy of the early warning system needs to be improved urgently.

[0003] The prior art discloses a train transportation safety warning device, including a track sensor, a microcomputer ground detection device and an on-board wireless transmission device. The track sensor is installed on the rails of the railway in the alarm area. A microcomputer ground detection device is provided next to the track. The track sensor is connected to the microcomputer ground detection device through a cable. A locomotive is provided with an on-board wireless transmission device, which is connected to the locomotive control circuit. The on-board wireless transmission device receives the signal transmitted by the microcomputer ground detection device and sends out an alarm message, prompting the driver to slow down and avoid accidents, which is conducive to the stable and smooth production. However, the study found the following technical problems: the data processing complexity of multi-sensor fusion is high, which is easy to cause system failure. Secondly, the reliability of a single sensor is not high and is easily interfered by environmental factors. Finally, the existing early warning system lacks intelligent decision support and cannot make the best choice in complex situations.

[0004] In view of the above-mentioned related technologies, a solution is now proposed. Summary of the invention

[0005] The purpose of this application is to provide a train safety driving warning device to solve the technical problems in the prior art of complex multi-sensor fusion processing, low reliability of a single sensor, susceptibility to interference from environmental factors, and lack of intelligent decision support.

[0006] The present application provides a train safety driving warning device, which adopts the following technical solution: A train safety driving warning device, comprising: Main control unit: installed in the train cab, receives signals from each module for comprehensive analysis and decision-making; Track state detection module: including a vibration sensor and a displacement sensor, through which the state changes of the rails are monitored in real time; Obstacle recognition module: including infrared sensors and laser radars, which detect whether there are obstacles ahead; Meteorological condition monitoring module: including a micro-meteorological station and a satellite data receiver, through which meteorological data along the route are acquired; Communication module: including GPRS module and Wi-Fi module, through which the GPRS module communicates with the ground control center in real time, and the Wi-Fi module is used for local data transmission; Display alarm module: including an LCD display screen and an audible and visual alarm, the display alarm module is installed in the train cab for real-time display and alarm.

[0007] By adopting the above technical solution, the main control unit is responsible for overall coordination and data processing. The track status detection module monitors the status changes of the rails in real time through vibration sensors and displacement sensors. The obstacle recognition module detects whether there are obstacles ahead through infrared sensors and lidars. The meteorological condition monitoring module obtains meteorological data along the line through micro-meteorological stations and satellite data receivers. The communication module is used for data transmission, and the display alarm module is used for real-time display and alarm. When the train starts, each module starts to work. After receiving the data from each module, the main control unit conducts comprehensive analysis and processing to determine whether the current environment is suitable for continued driving. If potential risks are found, the main control unit sends instructions to the display alarm module through the communication module. The display alarm module immediately displays a warning message and sounds an alarm through an audible and visual alarm to remind the driver to take corresponding measures.

[0008] Preferably, the main control unit includes a microprocessor and a data storage device. An AI analysis template is provided on one side of the microprocessor. The AI ​​analysis template can perform intelligent analysis on the data in the data storage device. The analysis steps are as follows: S1. Data cleaning and integration: Clean the collected data, remove noise and outliers, and integrate data from different sources; S2, feature extraction: extract key features from the cleaned data; S3, Model selection and training: Use historical data as training set and select deep learning model for training; S4. Real-time data analysis: Input the real-time collected data into the trained model for rapid analysis to identify potential risks in the current train operation status.

[0009] By adopting the above scheme, the main control unit is connected to the locomotive control circuit, so that the microprocessor and data storage device can realize the fusion of multi-source data, improve the accuracy and robustness of detection, improve the reliability and accuracy of the early warning system, reduce the false alarm rate, and effectively improve the safe driving ability of the train in complex terrain and severe weather conditions. At the same time, the AI ​​analysis template ensures the quality and consistency of the data through data cleaning and integration, and provides an accurate data set for subsequent analysis and model training, thereby improving the early warning accuracy of the entire system. Then, by extracting highly correlated features, the sensitivity of the model to important information is enhanced, and the accuracy and efficiency of the prediction are improved. The constructed model can effectively learn rules from complex data and improve the ability to predict potential risks, so as to make early warnings and realize real-time monitoring and immediate response. When the risk identified by the model exceeds the preset threshold, the early warning mechanism is triggered, and early warning information is issued to relevant personnel in a timely manner to remind them to take corresponding measures, which greatly enhances the safety of train operation.

[0010] Preferably, the vibration sensor is installed on both sides of the rails, and one vibration sensor is arranged every 5 meters, and is connected to the main control unit via a cable. The displacement sensor is installed at the bottom of the rails, and one displacement sensor is arranged every 10 meters, and is connected to the main control unit via wireless communication.

[0011] By adopting the above scheme, vibration sensors are installed on both sides of the rails, mainly used to monitor the vibration of the rails in real time. By arranging a vibration sensor every 5 meters, comprehensive monitoring of the rail status can be ensured. The high-frequency spatial distribution can capture local micro-changes and improve the sensitivity and accuracy of detection. This dense arrangement method can greatly improve the data collection density and accuracy, making data analysis more accurate, and can timely discover and warn potential risk points of the rails, thereby ensuring the safe driving of the train. The displacement sensor is installed at the bottom of the rail to monitor the displacement changes of the rails. A displacement sensor is arranged every 10 meters to transmit data to the main control unit through wireless communication. The use of wireless communication reduces the complexity and cost of wiring, and also facilitates the installation and maintenance of sensors. By combining the use of vibration sensors and displacement sensors, the system can comprehensively monitor the health of the rails, including vibration anomalies and displacement changes.

[0012] Preferably, the infrared sensor is installed on both sides of the front end of the train, and is connected to the main control unit through an RS485 interface. The laser radar is installed in the middle of the front end of the train, and is connected to the main control unit through an Ethernet interface.

[0013] By adopting the above scheme, infrared sensors are installed on both sides of the front of the train, mainly used to detect obstacles in front of the train, such as pedestrians, animals or other obstacles, especially at night or in low visibility. Infrared sensors detect the distance and speed of objects by emitting and receiving infrared radiation. Installing them on both sides of the front of the train can expand the monitoring range and ensure that potential obstacles are detected from multiple angles at the same time. Lidar is installed in the middle of the front of the train to accurately measure the distance and speed of objects in front of the train, as well as the outline and position of the objects, which is very critical for achieving high-precision obstacle detection and avoidance. Lidar measures the distance by emitting laser beams and receiving the reflected lasers, calculating the round-trip time of the lasers. Installing it in the middle of the front of the train can minimize blind spots and improve detection accuracy.

[0014] Preferably, the micro weather station is installed on the top of the train, and the micro weather station communicates with the main control unit through a GPRS module, and the satellite data receiver is installed at the rear of the train, and the satellite data receiver is connected to the main control unit through a USB interface.

[0015] By adopting the above solution, the micro weather station is installed on the top of the train, which is mainly used to monitor the meteorological conditions along the line in real time, such as temperature, humidity, wind speed, rainfall, etc. The micro weather station collects meteorological data through various sensors and transmits the data wirelessly to the main control unit through the GPRS module. Installing it on the top of the train can ensure that the sensor is not blocked by the car body, thereby improving the accuracy of the data. The satellite data receiver is installed at the rear of the train to receive the global positioning system GPS signal and other satellite data to obtain the precise position and speed information of the train. The satellite data receiver calculates the geographical location and speed of the train by receiving satellite signals, and transmits these data to the main control unit through the USB interface. Installing it at the rear of the train can reduce the body's blocking of satellite signals and improve the reception quality.

[0016] Preferably, the LCD display screen is connected to the main control unit via an HDMI interface, the sound and light alarm is connected to the main control unit via a relay, and the main control unit sends instructions to the LCD display screen via the Wi-Fi module, so that the LCD display screen immediately displays information and sounds an alarm through the sound and light alarm.

[0017] By adopting the above scheme, the LCD display is used to display key information such as real-time data, system status, and warning information to the train driver. The LCD display is connected to the main control unit through the HDMI interface. The HDMI interface can transmit high-quality video and audio signals to ensure that the displayed content is clear and real-time. The main control unit sends instructions to the LCD display through the Wi-Fi module to achieve instant update and display of data. The use of the HDMI interface ensures the stability and high speed of data transmission, so that the LCD display can respond quickly and accurately display complex information such as graphics, charts, and real-time alarms. This instant information feedback enhances the driver's situational awareness and decision-making ability, and improves the safety and efficiency of train operations. The sound and light alarm is connected to the main control unit through a relay. As an electrically controlled switch, the relay can quickly connect or disconnect the circuit under the command of the main control unit, thereby controlling the operation of the sound and light alarm. When the main control unit identifies a situation that requires an alarm based on the analysis results, it activates the sound and light alarm through the relay. Through immediate visual and auditory warnings, the driver can quickly realize the potential danger and take appropriate preventive measures.

[0018] Preferably, the sound and light alarm includes an alarm light and a buzzer, the alarm light is arranged in the train cab, and a buzzer is arranged at the bottom of the alarm light.

[0019] By adopting the above solution, the warning light is set in the train cab, and the buzzer is installed at the bottom of the warning light. This integrated design allows visual and auditory warning signals to be issued at the same time to enhance the warning effect. This design not only saves space, but also ensures that the sound is transmitted directly to the driver, improving the clarity and recognition of the sound warning. Humans have a strong instinctive reaction to flashes and sounds. This design uses this instinctive reaction to ensure that the driver's attention can be quickly obtained in an emergency. The combination of sound and light alarms can ensure that the driver can be immediately attracted by the warning signal even when he is busy or distracted, so as to take quick action.

[0020] Preferably, the operating steps of the safe driving warning device are: S1: Check whether each module is connected normally and confirm that the power is turned on; S2: Before starting the train, check whether the main control unit is in working condition and ensure that the signal transmission of each module is normal; S3: After starting the train, observe the parameters on the LCD display screen. If there is any abnormality, stop the train for inspection in time; S4: During driving, the driver should pay attention to the indications on the display alarm module. Once an alarm is detected, the driver should immediately slow down or stop the vehicle and continue driving only after eliminating the hidden danger.

[0021] By adopting the above solution, each module is checked one by one to see if it is connected normally and to confirm whether the power is turned on, which can prevent data transmission interruption or errors caused by equipment problems. The pre-startup inspection ensures that the system can operate efficiently when the train starts, avoiding data processing delays or errors caused by the system not being ready. At the same time, real-time data is displayed on the LCD screen, and the driver can check the status of various parameters at any time. Once an abnormal situation is found, the train should be stopped for inspection immediately. Through clear operating procedures and pre-inspection mechanisms, the system can be ensured to operate stably under various conditions.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Improved the reliability and accuracy of the early warning system, reduced the false alarm rate, and effectively improved the safe driving ability of trains in complex terrain and severe weather conditions; 2. Through multi-sensor data fusion and AI intelligent analysis, rapid identification of potential risks and intelligent decision-making are achieved, greatly shortening the emergency response time; 3. A real-time communication mechanism with the ground control center has been established to facilitate unified dispatch and management and improve overall operational efficiency.
