Description

Technical Field

[0001] The invention belongs to the technical field of rail transportation, and in particular relates to a driving suggestion device for a train in a difficult section where it is emergency self-traveling. Background Art

[0002] With the rapid development of the railway passenger transport industry, ensuring the safety of train operation has become the primary key. Train operation safety is not only related to the safety of passengers' lives and property, but also directly affects the overall efficiency and social trust of the railway system. During the operation of the train, an unexpected power supply failure will cause the train to be unable to travel to the station normally. At this time, the train driver needs to make a quick judgment on the emergency operation of the train and the difficult section to ensure that the train can safely reach the next station or other safe places. The difficult section for emergency self-driving of the train is the section where the train is difficult to run successfully due to the limited energy and power of the equipment when the train is powered by the on-board equipment. It is necessary to plan a reasonable operation strategy to complete the self-driving of the train in the difficult section.

[0003] At present, the judgment of difficult sections for emergency operation of trains mainly relies on the driver's driving experience, and there is no relatively mature technical equipment. Summary of the invention

[0004] In order to solve the problems existing in the prior art and realize accurate and rapid judgment of the difficult section for emergency train operation, the present invention provides a driving suggestion device for the difficult section for emergency self-running of train.

[0005] A train emergency self-driving difficult section driving suggestion device of the present invention comprises a difficult section suggestion unit, a train information unit, a human-machine interaction unit, a control unit and a memory storage module; the memory storage module is connected to the difficult section suggestion unit, the train information unit, the human-machine interaction unit and the control unit are all connected to the difficult section suggestion unit, and the control unit is connected to the human-machine interaction unit.

[0006] The difficult section suggestion unit includes a difficult section judgment module and a train self-driving driving suggestion module; the difficult section judgment module combines the line conditions and historical operation suggestion information provided by the memory storage module, the line information and train information of the train information unit, and judges whether the train can safely pass through the current section according to the line conditions and the current position and speed information of the train, and obtains the corresponding difficult section position information; the train self-driving driving suggestion module combines the difficult section position information to generate the running operation suggestion that the train can safely pass through the difficult section, and sends the difficult section information and driving suggestion information to the human-computer interaction unit.

[0007] The train information unit includes a satellite positioning module and a train information collection module, which sends the train's real-time position information, speed, and acceleration information to the difficult section suggestion unit.

[0008] The human-computer interaction unit includes a display, an indicator light and a voice prompter; the display is used to display the difficult section of the train emergency operation and the train emergency running operation suggestion information from the difficult section suggestion unit; the indicator light is used to display the status of the result of judging whether there is a difficult section, green indicates that there is no difficult section for the train emergency running, and red indicates that there is a difficult section for the train emergency running; the voice prompter is used to issue voice prompts and give operation suggestions for the train driver to refer to.

[0009] The control unit is used to receive operating instructions from the train driver for the device, including control instructions for the difficult section suggestion unit to start self-driving difficult section driving suggestions, stop suggestions, and re-judge suggestions, and switch instructions for the display screen of the human-computer interaction unit to enlarge, reduce, operate suggestion selection, indicator light and voice prompt, and send the operating instructions to the difficult section suggestion unit; when the self-driving difficult section driving suggestion is turned on, the difficult section suggestion unit initiates a data request to the memory storage module; after the train driver stops initiating self-driving difficult section driving suggestion instructions through the control unit, the difficult section suggestion unit stops sending data requests to the memory storage module.

[0010] The memory storage module uses an SD card to store basic information about the train's running route and historical operating advice information. When the driving advice status for the self-driving difficult section is turned on, it receives a data request signal from the difficult section advice unit and transmits the slope, curvature, length, and historical advice information of the self-driving route where the train is located. After the difficult section advice unit generates new difficult section information and operating advice, the memory storage module records the operating advice information for this time.

[0011] The specific working process of the driving suggestion device for a train emergency self-driving difficult section of the present invention is as follows:

[0012] Step 1: The driver issues control instructions to the driving suggestion device through the control unit, including starting the driving suggestion in the difficult driving section, stopping the suggestion, and re-judging the suggestion control instructions.

[0013] Step 2: The train information unit obtains the current real-time position of the train, train running speed, acceleration, line slope, curvature information through the satellite positioning module and the train information collection module, and sends it to the difficult section suggestion unit.

[0014] Step 3: The memory storage unit sends the route condition and historical maneuvering suggestion information to the difficult section suggestion unit.

[0015] Step 4: The difficult section suggestion unit obtains the line conditions, historical operation suggestions, current real-time train position, running speed, and acceleration information, and determines whether the train can pass through the current section based on the above information, generates the position information of the difficult section and the operation suggestions for the train to safely pass through the corresponding difficult section, and sends them to the human-computer interaction unit and the memory storage module.

[0016] Step 5: The human-machine interaction unit uses the display, indicator light and voice prompt to provide the driver with the difficult section location information and the maneuvering suggestions for the train to safely pass through the corresponding difficult section sent by the difficult section suggestion unit.

[0017] Furthermore, step 4 is specifically as follows:

[0018] S4.1: The difficult section suggestion unit receives the difficult section driving suggestion instruction issued by the control unit to start self-driving, and sends a data request to the memory storage module to obtain the line conditions, the operation status of past trains, and the historical operation suggestion information stored in the memory storage module.

[0019] S4.2: Obtain the basic train information and line information provided by the train information unit, including the train's current position, running speed, load, line slope, curve, and road surface conditions.

[0020] S4.3: Based on the train’s current position and historical operation data, analyze the route the train is about to travel, including slope, curve radius, signal signs, and track status.

[0021] S4.4: Combine the current speed and load information of the train with the line conditions, and determine whether the train can pass safely under the current conditions by calculating the train's dynamic performance in the section, including acceleration, braking distance, and friction between wheels and tracks; if the train can pass safely, the section is not a difficult section, otherwise the section is a difficult section.

[0022] S4.5: Based on the changes in train speed, signal light conditions, and changes in line conditions ahead, the safety judgment of the train passing through the section is continuously updated and adjusted, the location information of the difficult section is generated, and it is sent to the train self-driving driving suggestion module.

[0023] S4.6: The train self-driving driving suggestion module obtains the specific location information of the difficult section from the difficult section judgment module, including the section location, length, slope, curvature, signal status, and speed limit, and conducts comparative analysis based on the train's real-time data information and historical operation strategies.

[0024] S4.7: Generate manipulation suggestions:

[0025] If the difficult section contains curves, a large slope, or the signal ahead requires stopping, it is recommended that the train slow down appropriately before reaching the difficult section; if the difficult section is within the speed limit range, the module automatically calculates the difference between the current speed of the train and the speed limit requirement, and generates recommendations for slowing down or maintaining a constant speed as needed.

[0026] S4.8: Send the generated location information and manipulation suggestions of the difficult section to the human-computer interaction unit and the memory storage module.

[0027] The beneficial technical effects of the present invention are:

[0028] The present invention proposes a driving suggestion device for a train emergency self-moving difficult section. The device can provide the train emergency self-moving difficult section information and corresponding operation suggestions based on the train's current position, speed, line conditions and other information, achieve accurate and rapid judgment of the train emergency operation difficult section, provide prompt information for the driving driver, and effectively improve the success rate of the train emergency self-rescue.

[0041] The control unit 4 is used to receive the operating instructions of the device from the train driver, including control instructions to the difficult section suggestion unit 1 to start the self-driving difficult section driving suggestion, stop the suggestion, re-judge the suggestion, etc., and switch instructions to the display screen zoom in, zoom out, operate the suggestion selection, indicator light and voice prompt of the human-computer interaction unit 3, and send the operating instructions to the difficult section suggestion unit 1; when the self-driving difficult section driving suggestion is turned on, the difficult section suggestion unit 1 initiates a data request to the memory storage module 5; after the train driver stops initiating the self-driving difficult section driving suggestion instruction through the control unit 4, the difficult section suggestion unit 1 stops sending data requests to the memory storage module 5.

[0042] The memory storage module 5 uses an SD card to store basic information about the train's running route and historical operating advice information. When the device's self-driving difficult section driving advice state is turned on, it receives a data request signal from the difficult section advice unit 1 and transmits information such as the slope, curvature, length, and historical advice of the self-driving route where the train is located; after the difficult section advice unit 1 generates new difficult section information and operating advice, the memory storage module 5 records the current operating advice information.

It generates the position information of the difficult section and the operation suggestions for the train to safely pass through the corresponding difficult section and sends them to the human-computer interaction unit and memory storage module.

[0048] Step 5: The human-machine interaction unit uses the display, indicator light and voice prompt to provide the driver with the difficult section location information and the maneuvering suggestions for the train to safely pass through the corresponding difficult section sent by the difficult section suggestion unit.

[0049] Furthermore, the workflow of the difficult section suggestion unit is as follows: Figure 4 As shown, specifically:

[0050] S4.1: The difficult section suggestion unit receives the difficult section driving suggestion instruction issued by the control unit to start self-driving, and sends a data request to the memory storage module to obtain the line conditions, the operation status of past trains, historical operation suggestions and other information stored in the memory storage module.

[0054] S4.5: Based on the changes in train speed, signal light conditions, and changes in line conditions ahead, the safety judgment of the train passing through the section is continuously updated and adjusted, the location information of the difficult section is generated, and it is sent to the train self-driving driving suggestion module.

[0055] S4.6: The train self-driving driving suggestion module obtains the specific location information of the difficult section from the difficult section judgment module, including the section location, length, slope, curvature, signal status, speed limit, etc., and conducts comparative analysis based on the train's real-time data information and historical operation strategies.

[0056] S4.7: Generate manipulation suggestions:

[0057] If the difficult section contains curves, a large slope, or the signal ahead requires stopping, it is recommended that the train slow down appropriately before reaching the difficult section; if the difficult section is within the speed limit range, the module automatically calculates the difference between the current speed of the train and the speed limit requirement, and generates recommendations for slowing down or maintaining a constant speed as needed.
