[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will elaborate on each embodiment of this application in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of this application, many technical details are provided to help readers better understand this application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can still be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined and cross-referenced with each other on the premise of not being contradictory.

[0048] To facilitate the understanding of the embodiments of this application, the relevant content regarding the remote control of locomotives will be introduced here first.

[0049] A locomotive remote control system generally selects a locomotive through a remote control or a remote control device and performs close-range control operations on the controlled locomotive. With the development of technology, close-range control operations can no longer meet the requirements of remote control operations, so remote control technology has gradually developed.

[0050] In the prior art, for the remote control of locomotives, it is usually through an operator in the dispatching room using networks such as GPRS and Ethernet to remotely control the locomotive. Such a control method obviously cannot intuitively give accurate control instructions according to the status of the locomotive in real time, and an additional workstation needs to be established. The system architecture is relatively complex, with not only more links and the system stability needs to be improved, but also different types of locomotives may require different remote control stations to be configured, which is not only less applicable but also has a higher usage cost.

[0051] To solve the above technical problem of how to simplify the system architecture and stably establish the remote control of locomotives, the present invention proposes a locomotive remote control method. The following will specifically describe the implementation details of the locomotive remote control method in this embodiment. The following content is only the implementation details provided for convenience of understanding and is not necessary for implementing this solution.

[0052] Embodiment 1:

[0053] The locomotive remote control method in this embodiment can be applied to an electronic device with communication, computing, and data storage capabilities. Its specific process can be as Figure 1 shown. In this embodiment, there is an on-vehicle device on the locomotive for connecting to the locomotive remote monitoring system. The locomotive is connected to the locomotive remote monitoring system through the on-vehicle device to facilitate monitoring the status of the locomotive through the locomotive remote monitoring system. The locomotive remote control method includes steps 101-104, as Figure 2 shown, specifically including:

[0054] Step 101: Obtain all locomotive information monitored by the locomotive remote monitoring system through a wireless connection pre-established with the locomotive remote monitoring system.

[0055] Specifically, the locomotive remote monitoring system can obtain locomotive information of locomotives preparing to go on duty or in operation on the line through wireless communication, including locomotive operation information (such as locomotive model, vehicle number, line, kilometer post), locomotive operation status (speed, equipment status), train operation information (such as train number, driver number, load), etc. By interacting with the locomotive remote monitoring system, all locomotive information can be obtained, facilitating the operation of the operator.

[0056] In some examples, the execution entity of this method is a remote control system (i.e., a workstation). After connecting it to the locomotive remote monitoring system, the locomotive remote monitoring system can be regarded as the server of this workstation, so as to obtain all locomotive information of the locomotives through the locomotive remote monitoring system. Among them, a touch screen is set on the execution entity of this method, and the locomotive information is displayed on the touch screen after obtaining the locomotive information, facilitating the selection of the operator.

[0057] Step 102: Screen all the locomotive information by using preset remote control conditions to determine at least one selectable locomotive that meets the remote control conditions.

[0058] Specifically, the execution entity of this locomotive remote control method is a remote control system. Remote control conditions for screening locomotives that can be remotely controlled are preset in the remote control system, enabling the remote control system to make judgments according to the set rules and screen out locomotives that meet the remote control conditions.

[0059] Step 103: In response to the operator's operation request for remote control, determine the target remotely controlled locomotive from the several selectable locomotives according to the operator's operation request, and send remote control connection information to the on-vehicle equipment of the target remotely controlled locomotive.

[0060] Specifically, after the operator selects one of the several selectable locomotives displayed in the remote control system as the target remotely controlled locomotive, the remote control system immediately responds to the operator's operation request for remote control, confirms the target remotely controlled locomotive, and sends remote control connection information to the on-vehicle equipment of the target remotely controlled locomotive. The operator can select the target locomotive for remote control connection by himself, facilitating the selection and remote control of each locomotive within the scope of operation and management, and providing flexibility in use.

[0061] Step 104: Receive the remote control confirmation information sent by the on-vehicle equipment of the target remotely controlled locomotive, and establish a remote control connection with the on-vehicle equipment of the target remotely controlled locomotive.

[0062] Specifically, the execution entity of this step is the locomotive remote control system. After the target remotely controlled locomotive receives the remote control confirmation information, the on-vehicle equipment of the target remotely controlled locomotive sends the remote control connection information to the locomotive network control system of the target remotely controlled locomotive, enabling the locomotive network control system of the target remotely controlled locomotive to perform remote control connection confirmation, and then sending the remote control confirmation information to the on-vehicle equipment of the target remotely controlled locomotive and sending it to the locomotive remote control system through the on-vehicle equipment, so that the locomotive remote control system executes step 104, and then remotely controls the target remotely controlled locomotive.

[0063] In some embodiments, step 102, as Figure 3 shown, includes:

[0064] Step 1021: Screen out several locomotives that have applied for remote control from all the locomotive information as preselected locomotives;

[0065] Step 1022: Screen out at least one preselected locomotive that meets the zero-speed condition from the several preselected locomotives as selectable locomotives.

[0066] Specifically, the on-vehicle equipment on each locomotive can record whether the locomotive has applied for remote control, and can use the locomotive information to judge whether the locomotive is at zero speed, so as to conveniently screen out selectable locomotives that can be remotely controlled from multiple locomotives, facilitating the operator to select a target remotely controlled locomotive from the selectable locomotives for remote control, and only selecting selectable locomotives that meet the conditions to ensure the stability of remote control.

[0067] In some embodiments, sending the remote control connection information to the on-vehicle equipment of the target remotely controlled locomotive, as Figure 4 shown, includes:

[0068] Step 201: Establish a connection with the on-vehicle equipment of the target remotely controlled locomotive;

[0069] Step 202: Send verification information for security verification to the on-vehicle equipment of the target remotely controlled locomotive, so that the target remotely controlled locomotive conducts verification through the verification information and forms feedback information after successful verification;

[0070] Step 203: Receive the feedback information sent by the on-vehicle equipment of the target remotely controlled locomotive, and generate remote control connection information according to the feedback information, so as to send the remote control connection information to the on-vehicle equipment of the target remotely controlled locomotive.

[0071] Specifically, the execution entity of this method is the locomotive remote control system. This remote control system sends a connection to the target remotely controlled locomotive through the locomotive remote monitoring system, enabling the remote control system to establish a connection with the target remotely controlled locomotive. Furthermore, it can send verification information for the target remotely controlled locomotive to verify, so that the remote control connection information is sent only after successful verification, establishing a security authentication mechanism for both parties of the remote control between the remote control system and the target remotely controlled locomotive, and ensuring the security of remote control.

[0072] In some embodiments, sending verification information for security verification to the on-vehicle equipment of the target remotely controlled locomotive, so that the target remotely controlled locomotive verifies through the verification information and forms feedback information after successful verification, including:

[0073] Sending a public key for security verification to the on-vehicle equipment of the target remotely controlled locomotive, so that the on-vehicle equipment of the target remotely controlled locomotive verifies the public key, and generates a session key for encrypting interactive information and encrypts the session key using the public key to generate the feedback information after successful verification.

[0074] Specifically, the connection process between the locomotive remote control system and the target remotely controlled locomotive is established after being encrypted by the session key, so that all subsequent information interactions between the locomotive remote control system and the target remotely controlled locomotive need to be encrypted with this session key, ensuring the security of the remote control process and avoiding interference by others. At the same time, the key is updated when the locomotive remote control system establishes a remote control connection with other locomotives, that is, the key for the connection process of the locomotive remote control system to different locomotives is random, ensuring that the locomotive remote control system has high security each time a remote control is established and avoiding being easily cracked by others.

[0075] In some examples, the locomotive remote control system has a touch screen. After receiving the remote control confirmation information sent by the on-vehicle equipment of the target remotely controlled locomotive, the touch screen of the locomotive remote control system displays the selected controlled locomotive in the "remote control" mode, enabling the operator to confirm through the content displayed on the touch screen that the remote control of the locomotive can be started, improving the convenience of the operator's operation.

[0076] In some examples, receiving the remote control confirmation information sent by the on-vehicle equipment of the target remotely controlled locomotive, including:

[0077] Receiving the remote control confirmation information sent by the on-vehicle equipment of the target remotely controlled locomotive after being confirmed by the locomotive network control system of the target remotely controlled locomotive;

[0078] Wherein, the signal feedback process between the on-vehicle equipment and the locomotive network control system includes:

[0079] When the on-vehicle equipment of the target remotely controlled locomotive receives the remote control confirmation information, the on-vehicle equipment sends the remote control confirmation information to the locomotive network control system, so that when the locomotive network control system confirms that the target remotely controlled locomotive can be remotely controlled, it feeds back the remote control permission information to the on-vehicle equipment, and the on-vehicle equipment feeds back the remote control confirmation information according to the remote control permission information.

[0080] Specifically, after the locomotive network control system confirms that remote control is allowed, the on-vehicle equipment is used to feedback to the remote control system for remote control, so that the remote control connection is established on the basis of the locomotive network control system allowing remote control, thereby ensuring the stability of the remote control process and avoiding interference from the locomotive network control system.

[0081] In some embodiments, as Figure 5 shown, the remote control operation logic of the locomotive remote control system specifically includes the following steps:

[0082] Step 301, in the case of establishing a remote control connection with the target remotely controlled locomotive, obtain the remote control operation instruction of the operator, and send the remote control operation instruction to the on-vehicle equipment of the target remotely controlled locomotive, so as to be sent to the locomotive network control system of the target remotely controlled locomotive through the on-vehicle equipment of the target remotely controlled locomotive for execution;

[0083] Step 302, receive the locomotive state information after the on-vehicle equipment of the target remotely controlled locomotive is confirmed to be executed by the locomotive network control system.

[0084] Specifically, operation buttons, handles and other components are configured in the locomotive remote control system, so that the operator can generate remote control instructions by controlling the operation buttons, handles and other components, and then the locomotive remote control system sends the remote control instructions to the on-vehicle equipment of the target remotely controlled locomotive, and the on-vehicle equipment sends them to the locomotive network control system for execution, and then drives the corresponding execution unit to execute, which is convenient for the operator to perform remote control operations and improves the stability of the execution of each remote control operation instruction.

[0085] At the same time, the locomotive network control system feeds back the state after the instruction is executed to the locomotive remote control system through the on-vehicle equipment of the locomotive remote monitoring system, that is, each remote control instruction and the state of the controlled locomotive can be displayed on the display screen of the locomotive remote control system, which is convenient for the operator to operate.

[0086] In some embodiments, after the remote control ends, it is necessary to issue an instruction to exit the remote control to the target remotely controlled locomotive. Based on this, as Figure 6 shown, this locomotive remote control method further includes:

[0087] Step 401: Respond to the remote control exit instruction of the operator, and send the remote control exit instruction to the on-vehicle equipment of the target remotely controlled locomotive, so as to be sent to the locomotive network control system of the target remotely controlled locomotive through the on-vehicle equipment of the target remotely controlled locomotive, and control the target remotely controlled locomotive to exit the remote control state through the locomotive network control system;

[0088] Step 402: Receive the remote control exit confirmation signal after the on-vehicle equipment of the target remotely controlled locomotive is confirmed and executed by the locomotive network control system, and disconnect the connection status with the on-vehicle equipment of the target remotely controlled locomotive according to the remote control exit confirmation signal.

[0089] Specifically, the execution entity of this step is the locomotive remote control system. A display is configured on the locomotive remote control system, and a remote control exit button is set on the display. When it is necessary to cancel the remote control, the operator can click the remote control exit button, so that the locomotive remote control system sends the remote control exit instruction to the on-vehicle equipment of the target remotely controlled locomotive, and then sends it to the locomotive network control system through the planning equipment, so that the locomotive network control system controls the target remotely controlled locomotive to exit the remote control state and returns the remote control exit confirmation information. After the locomotive remote control system obtains the "remote control exit" confirmation information of the locomotive network control system, it disconnects the connection with the on-vehicle equipment of the locomotive remote monitoring system of the controlled locomotive, that is, cancels the connection and remote control. Through the above method, it is convenient for the operator to exit the remote control and restore the locomotive to its normal state. The remote control operation instruction and the remote control exit instruction of the locomotive remote control system are both conveyed on the basis of a stable and safe remote control connection between the controlled locomotive and the remote control system, which can ensure the stability and safety of the entire remote control process, and accurately control the controlled locomotive to exit the remote control operation, improving the stability of the entire remote control system.

[0090] The locomotive remote control method provided in this embodiment can directly control the locomotive based on the workstation of the locomotive remote monitoring system by integrating the data of the locomotive remote monitoring system, so as to realize the remote control of the locomotives within the operation jurisdiction, simplify the system architecture, merge and integrate the programs, realize the remote control function of the locomotive, improve the system stability, and ensure the safety of the locomotive remote control through the security authentication mechanism of both parties in the remote control.
