[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Figure 1 This is a flowchart illustrating a method for controlling the temperature of an electric locomotive during cold weather, as disclosed in an embodiment of this application. See also... Figure 1 As shown, the method for controlling the temperature of electric locomotives during cold weather may include:

[0044] Step 101: Obtain the cold-proof and temperature-regulating command, and control the electric locomotive to start the cold-proof and temperature-regulating mode based on the cold-proof and temperature-regulating command.

[0045] The cold-proofing and temperature-regulating command is a command input by relevant personnel to the electric locomotive when, based on the locomotive's operating status and the environment in which the train (i.e., the electric locomotive) is located, it is determined that insulation treatment is required. The cold-proofing and temperature-regulating command can be a command input by personnel through the electric locomotive's local human-machine interface, or a command received by the electric locomotive system from other devices via a wireless communication network. That is, obtaining the cold-proofing and temperature-regulating command can include: obtaining a cold-proofing and temperature-regulating command input by a user through the electric locomotive's local interactive device; or obtaining a cold-proofing and temperature-regulating command sent by a remote control center via a wireless communication network.

[0046] Step 102: In the cold-proof and warm-up mode, control the operation of the relevant systems of the electric locomotive.

[0047] Once an electric locomotive enters the anti-freezing and warming-up mode, it controls the operation of systems related to this function, such as the power supply system, heating system, and communication system. Only after these systems are operational can subsequent anti-freezing and warming-up controls and tests be effectively conducted. For example, in anti-freezing and warming-up mode, the electric locomotive needs to periodically perform automatic pantograph switching tests, air conditioning heating, and clamp anti-freezing tests. These controls and tests rely on the normal operation of the locomotive's heating, communication, and power supply systems.

[0048] Step 103: Obtain the status data of each relevant system during operation.

[0049] During the operation of systems related to cold-weather protection and temperature control in electric locomotives, status data of each relevant system can be periodically collected. This status data includes, but is not limited to, pantograph raising / lowering status, train medium voltage value, train movement status, and main circuit breaker closing status. There is no fixed limit to the period for collecting this status data; it can be configured based on the specific requirements of the application.

[0050] Step 104: When the status data of each relevant system during operation meets the set conditions, control the electric locomotive to start the automatic pantograph switching test process.

[0051] The set conditions can include multiple conditions to ensure that the systems and experiments related to cold protection and temperature control can operate normally and safely, thereby guaranteeing the reliable and safe conduct of subsequent cold protection and temperature control work. In an exemplary process, during the operation of the relevant systems, status data is collected. Based on the collected status data, the operating status of each relevant system or its constituent components is determined. The operating status is compared with the corresponding condition items in the set conditions, and the comparison result determines whether the relevant system or its constituent components meet the corresponding condition items in the set conditions.

[0052] Step 105: Transmit the operating status of each relevant system under the cold-proof and warm-up mode and the relevant data during the automatic bow replacement test process to the remote control center through the wireless communication network.

[0053] After the cold-proofing and temperature-regulating mode is activated, the corresponding system operates and conducts relevant tests. During this process, system status data and test data are transmitted to a remote control center on the ground via a wireless communication network. Staff at the remote control center can monitor the progress of the cold-proofing and temperature-regulating process in real time. The wireless communication network can be a railway mobile communication network (such as GSM-R, 5G-R) or a public network (4G / 5G) to achieve reliable and secure data transmission between the train and the ground.

[0054] The remote control center can be understood as a remote monitoring platform, which mainly includes a data receiving and parsing module and a visual interactive interface. The specific implementation will be described in detail in the following embodiments.

[0055] The electric locomotive cold-weather control method described in this embodiment enables closed-loop control through "vehicle-ground collaboration and data-driven" approaches. Using the onboard system as the core of intelligent diagnostic analysis and automated control, it executes the cold-weather control logic, assesses the testing process, and then transmits relevant train status data to the ground via a wireless communication network for ground maintenance personnel to evaluate the test results. This solution deeply integrates cold-weather control, automated testing, and remote intelligent operation and maintenance, forming a complete automated operation and maintenance solution.

[0056] The proposed solution enables automated operation of cold-proofing and temperature-regulating work, achieving unattended operation, reducing manpower, standardizing operation, avoiding human error, and transmitting relevant data to a remote control center during the cold-proofing and temperature-regulating process. This facilitates remote monitoring and control of electric locomotives by maintenance personnel, reducing the number of times personnel need to board the locomotives, improving overall work efficiency, and reducing investment costs.

[0057] In one implementation, the cold-proof temperature control command includes configuration data for an automatic pantograph switching test, and controlling the electric locomotive to start the pantograph switching test may include: controlling the electric locomotive to perform the automatic pantograph switching test according to the configuration data.

[0058] The configuration data may include, but is not limited to, the total execution time of the automatic pantograph-changing test and the interval between replacing the raised pantograph. For example, the total execution time of the automatic pantograph-changing test may be configured to be no less than 1 hour, and the interval between replacing the raised pantograph may be 15 minutes.

[0059] Of course, the cold protection and temperature control process can also include other tests, such as clamp antifreeze tests. The relevant parameters of the tests can be configured according to the needs of the scenario to meet the different needs of different users and different application scenarios, and improve the applicability of the solution.

[0060] In one implementation, the set conditions may include, but are not limited to, the following: ① pantograph raised, ② main circuit breaker closed, ③ all pantographs not disconnected, ④ train medium voltage within a first set range, ⑤ train stationary, ⑥ total air pressure within a second set range. The train has a 380V medium voltage busbar that supplies power to equipment such as the train's air conditioning system; normal medium voltage is essential for the equipment to function properly. Total air pressure refers to the pressure in the train's main ventilation ducts, providing power to all components on the train that require air pressure to drive.

[0061] If conditions ①②③ are not met, the train's high-voltage system will not function properly and the train will have no power source; if condition ④ is not met, the train's medium-voltage power supply equipment, such as the air conditioner, will not function properly; if condition ⑥ is not met, some components that require wind pressure to drive will not function properly.

[0062] Based on the aforementioned disclosure, the electric locomotive cold-weather control method may further include: if the status data of each relevant system during operation does not meet at least one of the set conditions, outputting the unmet condition item in the local interactive device of the electric locomotive, and / or sending the unmet condition item to the remote control center, wherein the condition item is at least one of the conditions included in the set conditions.

[0063] In other words, if all the above conditions are met simultaneously, the train can enter the cold-weather protection mode; if any condition is not met, the train will automatically exit the warm-weather protection mode and end the test. In cold-weather protection mode, the train periodically performs automatic pantograph changing tests, air conditioning heating, and clamp anti-freezing tests. The pantograph changing test requires the execution cycle and pantograph changing interval to be set in the warm-weather protection mode interface (corresponding to the signed configuration parameters) before it can be executed automatically. The detection and control logic of the corresponding set conditions can be preset in the electric locomotive system to ensure that after entering the cold-weather protection mode, the relevant workflows can be smoothly controlled according to the set control logic.

[0064] In one implementation, the method for controlling the cold-weather operation of an electric locomotive may further include: if it is determined that the operation of the relevant system is abnormal or the status data is abnormal, generating alarm information and sending the alarm information to the remote control center through a wireless communication network, wherein the alarm information includes a fault code and a fault level.

[0065] Alarm information can indicate the type and severity of the fault currently existing in the electric locomotive to the maintenance personnel at the remote control center, facilitating reasonable decision-making by the maintenance personnel based on the situation.

[0066] In other implementations, the alarm information also includes possible causes and suggested measures to provide maintenance personnel with more reference and guidance. For example, if the fault message indicates that the train's air conditioning cannot heat to the set temperature, the possible causes are refrigerant leakage or refrigerant failure. In this case, maintenance personnel at the remote control center can notify on-site personnel to board the train and check whether the air conditioning system has a refrigerant leak or failure. As another example, if the fault message indicates that the train's pantograph cannot be lowered after being raised, the possible cause is foreign objects at the bottom of the pantograph. In this case, the clearing device on the top of the train can be remotely activated to clear the area under the pantograph.

[0067] When it is determined that the operation of the relevant system is abnormal or the status data is abnormal, the automatic bow replacement test process can be automatically terminated to avoid safety accidents or damages that may be caused by the malfunction.

[0068] Furthermore, after sending the alarm information to the remote control center via a wireless communication network, the process may further include: receiving a control command sent by the remote control center and executing the control command, wherein the control command is an operation command determined based on the alarm information.

[0069] The above solution can provide decision support for remote operation and maintenance personnel, ensure timely fault detection and handling, and prevent serious delays in fault detection and handling.

[0070] The electric locomotive cold-weather control scheme provided in this application realizes intelligent automatic monitoring of cold-weather operation, automatic execution of pantograph replacement test, and remote monitoring of train status and fault data through functions such as automated control and remote data landing. It solves the problems of high frequency of manual inspection of winter cold-weather operation of Fuxing intelligent EMU, large amount of manual input, lagging information collection and harsh working environment, and realizes functional integration, automated control, status visualization and intelligent fault diagnosis.

[0071] To facilitate a better understanding and implementation of the technical solution of this application by those skilled in the art, an exemplary system composition of a vehicle-ground cooperative control system is hereby introduced. Figure 2 This is a schematic diagram of the composition and structure of the vehicle-to-ground cooperative control system disclosed in an embodiment of this application. See also... Figure 2 As shown, the vehicle-to-ground cooperative control system may include:

[0072] 1. Locomotive system:

[0073] Human-Machine Interface (HMI): Provides a graphical interface that generates an instruction setting interface including options for "cold-proof temperature control mode" and "automatic bow replacement test";

[0074] Central Control Unit (CCU): This is the vehicle's brain, and its embedded automation control logic module is used to: parse HMI commands; generate specific control command sequences (such as issuing a bow lowering command); receive and process feedback signals from various sensors; and perform fault diagnosis on the vehicle status by combining feedback status from various controllers.

[0075] Input / output module (IOM): monitors the overhead contact line voltage and current, and monitors and controls the pantograph raising and lowering status, etc.

[0076] Vehicle-mounted wireless transmission device (WTD): responsible for encapsulating the collected real-time data according to a preset protocol and transmitting it to the ground.

[0077] 2. Communication Network: The railway mobile communication network or public network is used to achieve reliable and secure data transmission between the train and the ground.

[0078] 3. Remote monitoring platform (ground server):

[0079] Data receiving and parsing module: Receives uploaded data from electric locomotives, and performs unpacking, verification, and parsing;

[0080] Visualized interactive interface: Provides maintenance personnel with a web dashboard that displays real-time data, alarm information, and fault reports in the form of graphs, curves, lists, etc., and supports historical data query and analysis tools.

[0081] Figure 3 This is a flowchart illustrating the cold-weather control method for electric locomotives disclosed in an embodiment of this application. (In conjunction with...) Figure 3 As shown in the example, the solution implementation includes the following process:

[0082] 1. Mode activation and parameter setting steps: Receive user input through the driver's cab HMI, activate the cold-proof and temperature-regulating mode, and set the target parameters and test options for the automatic pantograph switching test.

[0083] 2. Local automation control steps: The central control unit executes the pre-programmed sequence to control the operation of various systems of the electric locomotive, and under specific triggering conditions (such as reaching the set temperature or the user-set time period), it starts the automatic pantograph switching test subprocess, and sends instructions to the input / output module through the central control unit to control the automatic raising and lowering of the pantograph.

[0084] 3. Data Synchronization and Upload Steps Throughout the Entire Process: During the entire operation of the mode, sensor data (such as the pressure of the train's main air duct, pantograph status, the working status of the train's high-voltage system, and the working status of each subsystem) are continuously collected and uploaded to the ground platform via the onboard wireless device.

[0085] 4. Remote Fault Diagnosis and Alarm Procedure: Once the central control unit's diagnostic module detects an anomaly in the data, it immediately generates an alarm message containing the fault code, level, possible cause, and suggested measures. This data is then transmitted wirelessly to the ground, prompting relevant personnel to handle the situation. Examples of data anomalies include: ① During the temperature testing phase, any main circuit breaker changes from closed to open (except for automatic pantograph switching tests); ② During the temperature testing phase, any pantograph changes from raised to lowered (except for automatic pantograph switching tests); ③ During the temperature testing phase, the air conditioning temperature in a certain carriage falls below 18℃, etc.

[0086] 5. Ground data landing and analysis steps: The ground platform can monitor vehicle status and view fault codes through the landed data to confirm the vehicle status.

[0087] 6. Data-driven remote decision support steps: Maintenance personnel can remotely access detailed historical data curves and reports based on alarm information, analyze and assess the data, and choose to remotely terminate the task or guide on-site handling, forming a closed-loop decision-making process. For example, if a fault occurs in the passenger compartment electric heating control circuit breaker during the cold-weather operation, on-site operators need to board the vehicle to confirm the circuit breaker status and handle the fault.

[0088] During the implementation of the solution, the human-machine interface on the train can only view the fault record and cannot view the status of the corresponding component or system before the fault. However, the ground data can display the status of the component or system in the form of a timeline, which can analyze and trace the status before the fault.

[0089] In summary, current vehicle cold-weather maintenance primarily relies on manual labor, requiring manual monitoring of various components and the high-voltage components on the roof. This invention, through automated control technology, enables unattended operation, reducing manpower, standardizing procedures, and preventing human error. Remote data logging technology ensures fault traceability. Complete data from every test is recorded, facilitating in-depth post-test analysis of root causes and providing data for design improvements and maintenance strategy optimization. Simultaneously, it enables remote monitoring of vehicle data, reducing the number of times personnel need to be on-vehicle.
