[0054] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] During the railway transportation process, in the face of continuous operations under complex line conditions such as multiple curves, large bends, large slopes, and continuous undulating slopes, the level of the driver's operation has a greater impact on the energy consumption of the train, the smoothness of operation, the train impulse, and the accuracy of the transportation time. The main safety factors affecting train operation include line conditions, train operation equipment, and personnel factors, among which the most critical is the personnel factor.

[0056] The 20,000-ton heavy-haul train is the longest formation train regularly operated in the country at present. With the increase in the total weight and the number of vehicles of the train, the longitudinal force of the train increases exponentially, and problems such as hook breakage and separation, and failure of the locomotive hook buffer device are likely to occur during operation, posing a more severe test to the driver's operation, and putting forward new requirements for the application, training, management, etc. of the 20,000-ton heavy-haul train crew.

[0057] When the heavy-haul train is circulating braking and braking and relieving, the middle locomotive is impacted by a large longitudinal force. An operation error by the crew may cause damage to mobile equipment and fixed equipment, and even cause accidents such as hook breakage, separation, and derailment, bringing huge losses to the company and the country.

[0058] To ensure the safety of heavy-haul trains, the operation quality and safety of the trains are highly related to the operation level of the crew. It is necessary to operate the trains according to the requirements of line conditions, vehicle braking force, formation type, operation instruction manuals, and reminder cards. During the duty period of more than ten hours from the start to the stop of the train, the driver needs to maintain a high degree of mental concentration and be prepared to handle emergencies at any time. The training cycle for heavy-haul talents is relatively long. It takes about two years for a ten-thousand-ton driver to grow into an excellent twenty-thousand-ton main control driver. Relying on the traditional talent training concept, it has been unable to keep up with the increasing operation of twenty-thousand-ton heavy-haul trains and cannot meet the current development needs of heavy-haul transportation.

[0059] Prior to this, there has not been a similar system that can achieve the function of assisted driving for heavy-haul trains. Therefore, it is very important to develop a set of safe, stable, and punctual modular operation methods to guide the locomotive crew in operation and improve the safety analysis of management personnel. Based on this, this application proposes a method for assisted driving of heavy-haul trains with stable operation, which can improve the driving safety of heavy-haul trains.

[0060] The method for assisted driving of heavy-haul trains with stable operation provided by the embodiments of this application can be applied to the application environment as Figure 1 shown. Among them, the assisted driving system for heavy-haul trains with stable operation includes an on-vehicle guidance system and a ground analysis system 103. The on-vehicle guidance system includes an on-vehicle host 101 and a mobile display terminal 102. The on-vehicle host 101 is respectively connected to the locomotive monitoring device and the mobile display terminal 102, and the mobile display terminal 102 is also connected to the ground analysis system 103. Specifically, referring to Figure 1 , the locomotive monitoring device collects the current train operation data of the heavy-haul train and sends the current train operation data to the on-vehicle host 101; the on-vehicle host 101 sends the received current train operation data to the mobile display terminal 102. The mobile display terminal 102 generates the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train, as well as the recommended values of the train operation parameters and the train operation reminder voice of the heavy-haul train, displays the actual operation curve and the recommended operation curve of the target train operation parameters, the recommended values of the train operation parameters, and plays the train operation reminder voice to assist the driver of the heavy-haul train in operating the heavy-haul train stably, such as Figure 6 . In addition, the mobile display terminal 102 can also receive the processing instructions sent by the ground analysis system 103 (the processing instructions include at least one of a program upgrade instruction, a guiding formation data update instruction, and a train operation data file update instruction), and in response to the processing instructions, perform corresponding processing (the processing includes at least one of a program upgrade process, a guiding formation data update process, and a train operation data file update process).

[0061] Among them, the locomotive monitoring device refers to an important device on a heavy-haul train, which is used to monitor the running state of the heavy-haul train in real time, collect operation data, improve operation efficiency, and provide key information for other safety devices, so as to ensure the safe operation of the heavy-haul train. Specifically, it can refer to the locomotive TAX box (locomotive safety information integrated monitoring device). The on-vehicle host 101 is the core device of the heavy-haul train control system. It is equivalent to the "intelligent brain" of the heavy-haul train, responsible for processing operation data in real time, optimizing operation strategies, and controlling the coordinated work of each subsystem of the heavy-haul train. Specifically, it includes a sensor interface, a central processing unit (CPU), a storage module, a communication module, and a control output interface. The mobile display terminal 102 refers to a display terminal used to display the actual operation curve and recommended operation curve of the target train operation parameters of the heavy-haul train, the recommended values of train operation parameters, and play train operation prompt voices. Specifically, it can refer to various terminals with a display screen, such as a tablet computer, which is mainly set in the driver's cab. The ground analysis system 103 refers to a system that can identify the driver's operation violation items, generate correct operation information corresponding to the operation violation items, and assist the mobile display terminal 102 in program upgrade processing, guiding formation data update processing, and train operation data file update processing. It can be a terminal or a server. It should be noted that the ground analysis software is installed in the ground analysis system 103.

[0062] In an exemplary embodiment, as Figure 2 shown, a method for assisting in the smooth operation of a heavy-haul train is provided. Taking this method applied to Figure 1 the mobile display terminal in it as an example for description, it includes the following steps S201 to step S203. Among them:

[0063] Step S201, receive the current train operation data of the heavy-haul train sent by the on-vehicle host; the current train operation data is collected by the locomotive monitoring device and then sent to the on-vehicle host.

[0064] Among them, the current train operation data refers to data related to the operation of the heavy-haul train, such as speed, pipe pressure, traction / braking force, kilometer mark, locomotive type, locomotive number, train number, station number, route number, signal machine type, signal machine number.

[0065] Exemplarily, referring to Figure 1 , the locomotive monitoring device collects the current train operation data of the loaded train in real time and sends the collected current train operation data to the on-vehicle host; the on-vehicle host sends the received current train operation data to the mobile display terminal.

[0066] Step S202: Generate the actual operation curve and the recommended operation curve of the target train operation parameters for the heavy-haul train, as well as the recommended values of the train operation parameters for the heavy-haul train and the train operation prompt voice, based on the current train operation data.

[0067] Among them, the target train operation parameters refer to important train operation parameters, such as speed, pipe pressure, traction / braking force, etc.

[0068] Among them, the actual operation curve refers to the change curve obtained by converting the actual values of the target train operation parameters, such as Figure 6 the operation curve of the actual running pipe pressure, the operation curve of the actual running speed, and the operation curve of the actual running traction / braking force shown.

[0069] Among them, the recommended operation curve refers to the change curve obtained by converting the recommended values of the target train operation parameters, such as Figure 6 the operation curve of the recommended running pipe pressure, the operation curve of the recommended running speed, and the operation curve of the recommended running traction / braking force shown.

[0070] Among them, the recommended values of the train operation parameters refer to the recommended values of the train operation parameters for the heavy-haul train, such as Figure 6 the recommended running speed, pipe pressure, traction / braking force, etc. shown in the first row.

[0071] Among them, the train operation prompt voice refers to the voice corresponding to the current operation recommendation for the heavy-haul train, such as "Please pay attention to confirm the opening status of the derailer", "Please pay attention to the distances of the tenth, fifth, and third cars", "Please pay attention to testing the brakes", "The section from 10 km 600 m to 11 km 500 m is the release section, and the regenerative force is 350 kN". It should be noted that as Figure 6 shown, while the mobile display terminal displays the current operation recommendation "The section from 10 km 600 m to 11 km 500 m is the release section, and the regenerative force is 350 kN" on the interface, it plays the corresponding train operation prompt voice. In addition, the mobile display terminal can also display the charging and exhaust times during the air braking of the heavy-haul train on the interface and give voice reminders, such as "The remaining exhaust time is 10S".

[0072] Exemplarily, based on the patterned operation information of the heavy-haul train, such as a series of predefined operation steps, parameters or rules, the mobile display terminal performs a series of analysis and processing on the current train operation data to obtain the actual values and recommended values of the target train operation parameters of the heavy-haul train; respectively generates the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train according to the actual values and recommended values of the target train operation parameters of the heavy-haul train; then determines the recommended value of the train operation parameters of the heavy-haul train according to the recommended operation curve of the target train operation parameters; and finally determines the current operation recommendation of the heavy-haul train according to the recommended value of the train operation parameters of the heavy-haul train, and generates a train operation prompt voice corresponding to the current operation recommendation of the heavy-haul train.

[0073] Step S203: Display the actual operation curve and the recommended operation curve of the target train operation parameters, the recommended value of the train operation parameters, and play the train operation prompt voice to assist the driver of the heavy-haul train in smoothly operating the heavy-haul train.

[0074] Among them, the actual operation curve and the recommended operation curve of the target train operation parameters, the recommended value of the train operation parameters, and the played train operation prompt voice can provide reference for the driver of the heavy-haul train, facilitating the driver of the heavy-haul train to smoothly operate the heavy-haul train.

[0075] Exemplarily, referring to Figure 6 , the mobile display terminal displays on the interface the actual operation curve of the target train operation parameters (such as the operation curve of the actual running pipe pressure, the operation curve of the actual running speed, the operation curve of the actual running traction / braking force) and the recommended operation curve (such as the operation curve of the recommended running pipe pressure, the operation curve of the recommended running speed, the operation curve of the recommended running traction / braking force), the recommended value of the train operation parameters (such as speed, pipe pressure, traction / braking force), the remaining exhaust time (such as the remaining exhaust time of 10S), the current operation recommendation (such as 10 km 600 m to 11 km 500 m is the relief section, the regenerative force is 350 kN), and plays the train operation prompt voice (such as 10 km 600 m to 11 km 500 m is the relief section, the regenerative force is 350 kN) to assist the driver of the heavy-haul train in smoothly operating the heavy-haul train.

[0076] For example, during the high-speed brake test stage, the mobile display terminal issues a voice prompt "Please note the brake test" and pops up an information window "Please note the brake test". After receiving the voice prompt, the driver of the heavy-haul train starts the brake test operation of reducing the pressure of the heavy-haul train by 50 kPa. At the same time, on the terminal screen of the mobile display terminal, data such as the recommended running speed, regenerative force, and running pipe pressure will be displayed. The driver of the heavy-haul train can operate according to these recommended values. At the same time, the mobile display terminal will record the charging and exhaust times of the heavy-haul train during air braking and give a voice reminder.

[0077] In the above-mentioned auxiliary driving method for smooth operation of heavy-haul trains, the current train operation data of the heavy-haul train sent by the on-vehicle host is received through a mobile display terminal; the current train operation data is collected by the locomotive monitoring device and then sent to the on-vehicle host; then, based on the current train operation data, the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train, as well as the recommended value of the train operation parameters of the heavy-haul train and the train operation prompt voice, are generated; finally, the actual operation curve and the recommended operation curve of the target train operation parameters, the recommended value of the train operation parameters, and the train operation prompt voice are displayed and played to assist the driver of the heavy-haul train in smoothly operating the heavy-haul train; in this way, during the running process of the heavy-haul train, according to the received current train operation data of the heavy-haul train sent by the on-vehicle host, the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train, as well as the recommended value of the train operation parameters of the heavy-haul train and the train operation prompt voice, are generated, and the actual operation curve and the recommended operation curve of the target train operation parameters, the recommended value of the train operation parameters, and the train operation prompt voice are displayed and played, enabling the driver of the heavy-haul train to smoothly operate the heavy-haul train based on the displayed actual operation curve and the recommended operation curve of the target train operation parameters, the recommended value of the train operation parameters, and the played train operation prompt voice, achieving the purpose of assisting the driver of the heavy-haul train in smoothly operating the heavy-haul train, being beneficial to improving the driving safety of the heavy-haul train, and avoiding the defect that the driving safety of the heavy-haul train is relatively low due to the driver's operation errors.

[0078] In an exemplary embodiment, as Figure 3 shown, the above-mentioned step S202, generating the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train, as well as the recommended value of the train operation parameters of the heavy-haul train and the train operation prompt voice according to the current train operation data, specifically includes the following steps S301 to S304. Among them:

[0079] Step S301, through the modularized operation model of the heavy-haul train, based on the preset operation mode, analyze and process the current train operation data to obtain the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train.

[0080] Step S302, generate the recommended value of the train operation parameters of the heavy-haul train according to the recommended operation curve of the target train operation parameters.

[0081] Step S303, generate the current operation recommendation of the heavy-haul train according to the recommended value of the train operation parameters of the heavy-haul train.

[0082] Step S304, generate the voice corresponding to the current operation recommendation as the train operation prompt voice of the heavy-haul train.

[0083] Among them, the patterned operation model is a model that guides or controls the operation of heavy-haul trains based on preset patterns or rules. This model usually includes a series of predefined operation steps, parameters, or rules for guiding the operation behavior of heavy-haul trains under specific conditions. It provides optimal operation suggestions for the drivers of heavy-haul trains by analyzing and calculating various factors (such as line profile, speed, traction / braking force, train pipe pressure, etc.) during the operation of heavy-haul trains.

[0084] Among them, the preset operation patterns can refer to snow mode, long and steep downhill mode, tunnel mode, etc.

[0085] Among them, the current operation suggestion of the heavy-haul train refers to the optimal operation suggestion of the heavy-haul train, such as "Please pay attention to confirm the opening status of the derailer", "Please pay attention to the distances of the tenth, fifth, and third cars", "Please pay attention to testing the brakes", "The section from 10 km 600 m to 11 km 500 m is the release section, and the regenerative force is 350 kN".

[0086] Exemplarily, the mobile display terminal pre-establishes the patterned operation model of the heavy-haul train, and through the patterned operation model of the heavy-haul train, based on the preset operation patterns, analyzes and processes the current train operation data to obtain the actual values and suggested values of the target train operation parameters of the heavy-haul train; respectively generates the actual operation curve and the suggested operation curve of the target train operation parameters of the heavy-haul train according to the actual values and suggested values of the target train operation parameters of the heavy-haul train; then, determines the suggested value of the train operation parameters of the heavy-haul train in real time according to the suggested operation curve of the target train operation parameters; finally, determines the corresponding optimal operation suggestion according to the suggested value of the train operation parameters of the heavy-haul train as the current operation suggestion of the heavy-haul train, and generates the train operation prompt voice corresponding to the current operation suggestion of the heavy-haul train; for example, analyzes and processes the suggested value of the train operation parameters of the heavy-haul train through a pre-trained operation suggestion prediction model (such as a neural network model) and outputs the corresponding optimal operation suggestion.

[0087] In this embodiment, by generating the actual operation curve and the suggested operation curve of the target train operation parameters of the heavy-haul train, as well as the suggested value of the train operation parameters of the heavy-haul train and the train operation prompt voice, it is convenient to subsequently display the actual operation curve and the suggested operation curve of the target train operation parameters, the suggested value of the train operation parameters, and play the train operation prompt voice on the mobile display terminal, providing auxiliary data for the drivers of heavy-haul trains, enabling the drivers of heavy-haul trains to smoothly operate the heavy-haul trains based on these auxiliary data, thereby improving the driving safety of heavy-haul trains.

[0088] In an exemplary embodiment, step S203 above, which shows the actual operation curve and the recommended operation curve of the target train operation parameters, as well as the recommended values of the train operation parameters, specifically includes the following: identifying a first display area and a second display area in the terminal interface of the mobile display terminal; displaying the recommended values of the train operation parameters in the first display area, and displaying the actual operation curve and the recommended operation curve of the target train operation parameters in the second display area.

[0089] Among them, the first display area refers to the display area of the recommended values of the train operation parameters in the terminal interface of the mobile display terminal.

[0090] Among them, the second display area refers to the display area of the actual operation curve and the recommended operation curve of the target train operation parameters in the terminal interface of the mobile display terminal.

[0091] Exemplarily, referring to Figure 6 , the mobile display terminal displays the recommended values of the train operation parameters in the first display area, such as speed, pipe pressure, traction / braking force, etc., and displays the actual operation curve and the recommended operation curve of the target train operation parameters in the second display area, such as the operation curve of the actual running pipe pressure, the operation curve of the recommended running pipe pressure, the operation curve of the actual running speed, the operation curve of the recommended running speed, the operation curve of the actual running traction / braking force, the operation curve of the recommended running traction / braking force, etc.

[0092] Furthermore, as Figure 6 shown, the mobile display terminal can also display speed limits, kilometer markers, distances, remaining exhaust times (such as remaining exhaust time 10S), current operation recommendations (such as the relief section from 10 km 600 m to 11 km 500 m, and the regenerative force is 350 kN), etc. in the first display area.

[0093] In this embodiment, by displaying the recommended values of the train operation parameters in the first display area of the mobile display terminal and displaying the actual operation curve and the recommended operation curve of the target train operation parameters in the second display area of the mobile display terminal, the purpose of displaying different information in different areas is achieved, which is beneficial for the driver of the heavy-haul train to intuitively and clearly see the recommended values of the train operation parameters, the actual operation curve and the recommended operation curve of the target train operation parameters.

[0098] Exemplarily, the mobile display terminal collects the actual train operation data of the driver of the heavy-haul train and sends the actual train operation data to the ground analysis system. The ground analysis system inputs the received actual train operation data into a pre-trained operation violation item recognition model, analyzes the actual train operation data through the pre-trained operation violation item recognition model, obtains the prediction probability of the driver under each preset operation violation item, and takes the preset operation violation item with the prediction probability greater than the preset probability as the operation violation item of the driver and generates the correct operation information corresponding to the operation violation item. Then, the operation violation item of the driver and the correct operation information corresponding to the operation violation item are sent to the mobile display terminal. The mobile display terminal receives the operation violation item and the correct operation information corresponding to the operation violation item returned by the ground analysis system, and displays the operation violation item and the correct operation information corresponding to the operation violation item in the form of a pop-up window on the terminal interface of the mobile display terminal, such as "During the high-speed brake test stage, the heavy-haul train cannot be pressurized for the brake test operation, and the heavy-haul train should be depressurized by 50 kPa for the brake test operation".

[0099] In this embodiment, by receiving the operation violation items returned by the ground analysis system and the correct operation information corresponding to the operation violation items, and displaying the operation violation items and the correct operation information corresponding to the operation violation items on the terminal screen of the mobile display terminal, it is beneficial for the driver to timely discover his own operation violation items and learn the correct operation information corresponding to the operation violation items, achieving the purpose of self-discovery, self-improvement and self-promotion.

[0106] In an exemplary embodiment, as Figure 4 shown, another heavy-haul train smooth operation auxiliary driving method is provided. Taking the application of this method to a mobile display terminal as an example for description, it includes the following steps S401 to S410. Among them:

[0107] Step S401: Receive the current train operation data of the heavy-haul train sent by the in-vehicle host; the current train operation data is collected by the locomotive monitoring device and then sent to the in-vehicle host.

[0108] Step S402: Based on the preset operation mode, analyze and process the current train operation data through the mode-based operation model of the heavy-haul train to obtain the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train.

[0109] Step S403: Generate the recommended value of the train operation parameters of the heavy-haul train according to the recommended operation curve of the target train operation parameters.

[0113] Among them, after step S406, there are two step branches, namely steps S407 to S409, and step S410.

[0114] Step S407: Collect the actual train operation data of the driver of the heavy-haul train.

[0118] In the above-mentioned auxiliary driving method for smooth operation of heavy-haul trains, during the running of heavy-haul trains, according to the current train operation data of the heavy-haul train sent by the on-board host, the actual operation curve and the recommended operation curve of the target train operation parameters of the heavy-haul train, as well as the recommended values of the train operation parameters and the train operation prompt voice of the heavy-haul train are generated, and the actual operation curve and the recommended operation curve of the target train operation parameters, the recommended values of the train operation parameters are displayed, and the train operation prompt voice is played, so that the driver of the heavy-haul train can smoothly operate the heavy-haul train based on the displayed actual operation curve and the recommended operation curve of the target train operation parameters, the recommended values of the train operation parameters, and the played train operation prompt voice, achieving the purpose of assisting the driver of the heavy-haul train to smoothly operate the heavy-haul train, being beneficial to improving the driving safety of the heavy-haul train, and avoiding the defect that the driving safety of the heavy-haul train is relatively low due to the driver's operation error.

[0119] To more clearly illustrate the auxiliary driving method for smooth operation of heavy-haul trains provided by the embodiments of the present application, the following uses a specific embodiment to specifically describe the auxiliary driving method for smooth operation of heavy-haul trains. In an exemplary embodiment, referring to Figure 5 , an auxiliary driving system for smooth operation of heavy-haul trains is provided. The system mainly consists of two parts: an on-board guidance system and a ground analysis system. It can not only provide auxiliary driving functions, but also play functions such as the daily training of drivers and data analysis for management personnel. The specific content is as follows:

[0120] Referring to Figure 5 , the on-board guidance system includes a mobile display terminal and an on-board host. The on-board host real-time collects signal data such as speed, pipe pressure, and kilometer mark of the monitoring device TAX box, and then wirelessly transmits it to the mobile display terminal. The mobile display terminal converts the received data into the actual train operation curve, voice prompt, etc. The on-board guidance system real-time collects information such as locomotives, formations, kilometer marks, locomotive instruments, speed limit values, and locomotive signals, and combines content such as different formations, line conditions, and operation prompt cards to provide reference for the crew's operation.

[0121] The ground analysis system mainly consists of modules such as operation data, comprehensive analysis, and statistical information. The operation data module can perform combined condition queries according to train number, locomotive number, driver's work number, start and end times. The comprehensive analysis module can retrieve individual smooth operation violation items. The statistical information module can perform statistics and classification on all smooth operation violation items within a certain period. The ground analysis system first parses the LKJ file (i.e., the data file related to the train operation monitoring device), and then compares and analyzes signals such as train speed, brake pipe pressure, locomotive traction force, regeneration force, and line kilometer mark with the smooth operation rule items of the train to retrieve operation violation items, realizing automatic analysis and evaluation.

[0122] The functions of the associated interfaces are as follows: 1) In-vehicle host: It provides a wireless hotspot for the mobile display terminal. After the mobile display terminal is connected, it can obtain the data collected by the in-vehicle host; 2) Mobile display terminal: It communicates with the in-vehicle host wirelessly to obtain the train formation, locomotive-collected data information sent by the in-vehicle host; 3) Dispatching room: It provides a wireless hotspot for the mobile display terminal. After the mobile display terminal is connected, it can obtain information such as upgrading programs through the ground analysis software, updating the guiding formation data, and updating materials; 4) Ground analysis software: It performs background data maintenance such as version control of the mobile display terminal program, maintenance of guiding formation data, management of material files, and user management.

[0123] Taking the operation process of the crew as the main line, it demonstrates the specific implementation methods of the heavy-haul train smooth operation auxiliary driving system in the entire operation link.

[0124] 1. Crew attendance: When the crew member attends work in the dispatching room, they use the mobile display terminal to connect to the wifi hotspot of the dispatching room and enter the driver number, co-driver number, and student's work number on the attendance interface of the mobile display terminal to complete the attendance information registration. After the mobile display terminal is connected, it can obtain all the information of this train operation, such as upgrading programs through the ground analysis software, updating the guiding formation data, up / down line, locomotive number, announcements of slow sections, etc.

[0125] 2. Shunting operation: After the crew member completes the attendance, the locomotive crew goes to the yard to pick up the train and conducts shunting operations. After the locomotive starts, the crew member uses the mobile display terminal to connect to the wifi hotspot of the in-vehicle host. The mobile display terminal will obtain the train operation information from the locomotive's TAX signal box. The information content includes train operation information such as "locomotive type", "locomotive speed", "locomotive number", "train number", "station number", "route number", "kilometer marker", "signal type", and "signal number". During the shunting operation, the in-vehicle display terminal gives operation instructions to the locomotive crew through two prompting methods: voice and picture. For example, before the locomotive passes the derailer, the mobile display terminal gives a voice prompt "Please pay attention to confirm the opening status of the derailer", and during the coupling operation, it gives a voice prompt "Please pay attention to the distances of ten, five, and three cars".

[0126] 3. Main line operation: Taking the most complex main line operation scenario as an example, take the case of a 20,000-ton combined heavy-haul train performing cyclic air braking on a long downhill section. When operating the locomotive, the mobile display terminal will obtain train operation information from the locomotive's TAX signal box and also access the locomotive network to obtain locomotive operation data, including traction / braking force, main breaker status, main air pressure, network voltage, etc. Through the pre-stored pattern-based operation model, it can achieve real-time comparison and display of the recommended operation curve and the actual operation curve of the line profile, speed, traction / braking force, and train pipe pressure, and issue voice prompts and the actual speed operation curve of the train. For example: During the high-speed brake test stage, the mobile display terminal issues a voice prompt "Please pay attention to the brake test" and pops up an information window. After receiving the prompt, the crew starts the brake test operation of reducing the train pressure by 50 kPa. At the same time, on the terminal screen, data such as the recommended running speed, regenerative force, and running pipe pressure will be displayed (refer to Figure 6 ), and the driver can operate according to the recommended values. At the same time, the mobile display terminal will record the charging and discharging time of the train during air braking and give voice reminders.

[0127] 4. Ground analysis: After the locomotive completes the traction task, data transmission between the locomotive and the ground system is realized through wireless transmission. The train operation ground server stores, analyzes, and replays in real time online and timely feedbacks the locomotive operation status data. After the data is uploaded to the ground analysis software, it guides drivers and other management personnel to use the ground analysis system to achieve comprehensive analysis and evaluation of operation. The analysis and evaluation software divides locomotive operation into modules such as starting, stopping, traction / regenerative braking, electro-pneumatic combined braking, passing neutral section, signal, network voltage, slow running, and safety control.

[0128] The above embodiments can achieve the following technical effects:

[0129] 1. Optimize and continuously improve the smooth operation method of heavy-haul trains and improve the driver's operation level.

[0130] 2. Reduce the driver's work pressure. During cyclic braking on long slopes, functions such as countdown display of train charging and discharging, automatic calculation of braking distance, voice reminders at key sections such as temporary speed limits and passing neutral sections can eliminate the phenomena of drivers' manual records and ineffective mutual control between crew members, effectively reducing the driver's work pressure.

[0131] 3. Shorten the training period for new drivers. This system can provide a new training mode different from the traditional master-apprentice training, shorten the training period for drivers of heavy-haul locomotives, and achieve employees' self-discovery, self-improvement, and self-promotion.

[0132] 4. Utilize advanced big data technology to manage and process a large amount of data in multiple specialties, conduct quantitative analysis of train operation records, automatically identify drivers' illegal operations, and evaluate the quality of operations.

[0133] 5. The software platform adopts an open structure and a modular management design concept, provides open maintenance and management for various databases and operation rules, and is applicable to different transport organization modes and evaluation rules.

[0134] 6. Improve the existing training method of "mentoring by master", and with the application of the auxiliary driving and evaluation system, further shorten the training cycle of new employees and promote the implementation of rules and regulations and operation standards by means of more scientific, intelligent monitoring, analysis, prompting and evaluation.

[0135] 7. Break through traditional manual analysis, realize automated and scientific and rational analysis, improve analysis efficiency, reduce the work pressure of analysts, conduct full-coverage analysis, and prevent violations during the operation of train crew.
