Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and in particular to a method and device for real-time transmission and processing of train data. Background Art

[0002] Traditional train control and monitoring systems (TCMS) are widely used in train operation management, providing real-time monitoring of various operating conditions, including traction, braking, axle temperature, speed, pyrotechnics, door locks, network communications, and other key indicators. TCMS systems use onboard sensors, data collection devices, and communication modules to comprehensively collect and monitor train data, ensuring train safety and stability.

[0003] Currently, the monitoring data of the train TCMS system is usually displayed through fixed display devices inside the train, including but not limited to:

[0004] Cab display screen: usually installed in the train cab, allowing the train driver to view the train operation status in real time and process various data during driving.

[0005] Mechanic room monitoring equipment: Display equipment is installed in the train's mechanic room for maintenance personnel to view various status data of the train so as to diagnose and handle train faults.

[0006] Fixed computer terminal: It is placed inside the train car or other control areas for staff to view train data, provide fault analysis and alarm processing.

[0007] These traditional display methods fix data and personnel to specific locations, resulting in certain limitations in train status monitoring and fault handling.

[0008] The existing technology has the following shortcomings and deficiencies:

[0009] 1. Spatial limitations: Traditional TCMS systems rely on fixed displays within trains, forcing operators to remain within specific control areas to view real-time train status information. For example, mechanics can only view train status from the mechanic's room, while drivers can only view operating status from the driver's cab. This limitation prevents operators from quickly obtaining real-time data from other locations (such as within train cars or at equipment sites), hindering timely response to unexpected failures.

[0010] 2. Information Lag: When mechanics or operators need to inspect equipment in different areas of the train, they must rely on fixed-position displays to view data. If equipment fails or status changes, mechanics may miss real-time information, delaying their response. For example, if a device's status change isn't displayed promptly, the mechanic can't access the most up-to-date data when troubleshooting a problem, missing the optimal opportunity to address it.

[0011] 3. Inconvenient operation and poor flexibility: Existing TCMS data viewing methods are limited to fixed devices, which prevent operators from flexibly accessing data at any time according to work needs. In the event of a train failure, the operator may need the cooperation of multiple staff members, often with one person responsible for operating the equipment and another for data review. This division of labor increases workload and reduces work efficiency.

[0012] 4. Lack of convenience and real-time feedback: Traditional TCMS systems rely on display devices and computer terminals, and are unable to provide immediate feedback to on-site personnel. This is particularly problematic in emergency situations, when mechanics may need to visit different equipment locations for inspection or operation. During this process, the display devices cannot provide instant status updates, making it impossible for personnel to track changes in train status, hindering their ability to respond quickly.

[0013] 5. Inefficient maintenance: Because operators frequently move between different areas and rely on fixed equipment to view data, troubleshooting often takes a long time. For example, if a device fails or changes status, operators may need to travel to the driver's cab or mechanic's room to view data and determine the cause of the problem. This leads to inefficient train inspection and troubleshooting, increasing maintenance costs and time.

[0014] As a critical data acquisition and monitoring system for trains, the design and implementation of the TCMS system typically relies on embedded computer systems and onboard communication networks. These devices transmit various train data to the monitoring system in real time through sensors, data acquisition cards, and various communication protocols (such as the CAN bus and Ethernet). Traditional TCMS systems transmit data to operators via onboard displays. However, in many cases, the limitations of the display devices and the space required for operators make viewing and processing real-time data difficult, especially when cross-regional data exchange and troubleshooting are required.

[0015] With the rapid development of mobile internet and smart terminal technologies, portable devices (such as smartphones, tablets, and handheld devices) have become essential vehicles for data exchange and display in many fields. In complex systems like trains, the ability to transmit real-time monitoring data to handheld devices is particularly important for improving operational flexibility and responsiveness. This also provides new insights into overcoming the limitations of existing technologies. Summary of the Invention

[0059] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any manner.

[0060] Figure 1 FIG. 1 is a flow chart of a method for real-time transmission and processing of train data provided by an embodiment of the present invention. Figure 1 As shown, the train data real-time transmission and processing method provided by the embodiment of the present invention is executed based on a system architecture, wherein the system architecture includes a handheld terminal server and a handheld mobile terminal connected to each other, and the handheld terminal server is further connected to an on-board subsystem; the train data real-time transmission and processing method includes:

[0061] Step S1: The handheld terminal server receives the TRDP data sent by the vehicle-mounted subsystem, parses the TRDP data, and obtains the vehicle-mounted subsystem collection data.

[0062] Step S2: The handheld terminal server performs a first data processing on the data collected by the onboard subsystem to obtain derived data; based on the pre-acquired train topology information, the data collected by the onboard subsystem and the derived data, a full data packet marked with the physical location of the train is generated.

[0063] Step S3: The handheld terminal server sends the full data packet to the handheld mobile terminal, so that the handheld mobile terminal performs a second data processing on the full data packet and displays the processed terminal data.

[0064] In the above step S1, the device handheld terminal server receives the TRDP data sent by the vehicle-mounted subsystem, parses the TRDP data, and obtains the vehicle-mounted subsystem collection data. The device can be a computer device that executes the method. The acquisition, storage, use, and processing of data in the technical solution of this application are in compliance with relevant regulations. Figure 2 As shown, the vehicle-mounted subsystems may include a traction system, a high-voltage system, a braking system, a pyrotechnic detection system, an axle temperature detection system, and a vibration detection system.

[0065] like Figure 3As shown, the handheld terminal server can be a device included in the TCMS network. The handheld terminal server receives TRDP data sent by the onboard subsystem. TRDP (Train Real-Time Data Protocol) is a real-time data protocol for train communications. It is based on the standard TCP / IP protocol stack and is mainly used for data communication in the rail transit field. The TRDP protocol is designed to improve real-time performance and ensure reliability, and is suitable for the needs of railway control systems.

[0066] TRDP data may include protocol layer information such as data sending sequence, message type identifier, user data, data length, header checksum, etc. By parsing the TRDP data, user data (Comid data) is obtained, that is, the data collected by the on-board subsystem, thereby realizing the collection of status information such as traction, braking, axle temperature, fireworks, and network communication during train operation.

[0067] In the above step S2, the handheld terminal server performs a first data processing on the data collected by the onboard subsystem to obtain derived data; based on the pre-acquired train topology information, the data collected by the onboard subsystem, and the derived data, a full data packet marked with the physical location of the train is generated. The handheld terminal server performs a first data processing on the data collected by the onboard subsystem to obtain derived data, including:

[0068] The data collected by the vehicle-mounted subsystem is converted and processed based on its offset and data type to obtain the original data. The handheld terminal server has a built-in parameter parsing dictionary that records the byte offset, bit offset, data type, and formula rules corresponding to each parameter. Based on the data collected by the vehicle-mounted subsystem and combined with the offset and data type (e.g., Boolean type data, 16-bit integer, 32-bit integer) in the parameter parsing dictionary, all original parameters are parsed. For example, when parsing axle temperature data, the dictionary locates the corresponding byte segment, extracts the binary data, and converts it into the actual temperature value.

[0069] The raw data is processed to obtain actual data values; according to the formula rules in the parameter parsing dictionary, the raw data is processed, including proportional operations (such as multiplication or division conversion), addition and subtraction operations (such as compensation correction), logical operations (AND, OR, NOT judgment), etc. For example, the raw voltage data is converted to the actual voltage value using the proportional formula and stored in the system memory for subsequent use.

[0070] The actual data value and the original data are subjected to multi-variable association processing to obtain the derived data. The parameter combinations that need to be processed collaboratively (such as the linkage relationship between brake pressure and brake command) are recorded through the multi-parameter operation dictionary built into the handheld terminal server. This step performs operations on the associated parameters, such as multi-variable addition and subtraction, extreme value extraction (taking maximum / minimum value), state judgment (such as judging whether the signal is 0 / 1) or feature extraction (such as judging which parameter is the corresponding characteristic value in a set of multi-parameter sets to obtain the label of the parameter corresponding to the characteristic value) to generate new derived data. For example, by comparing multiple shaft temperature data, the shaft position number with abnormal temperature is automatically marked, and the operation result is stored in the memory.

[0071] like Figure 3 As shown, the handheld terminal server can obtain train topology information (such as the car marshaling structure) through the train gateway and use this topological data to mark the unit location (such as car 1, car 8) for the data. Subsequently, the corresponding car number information, unit number, and location coordinates are added to the data previously stored in the memory to ensure that the data has a complete train space identification. The data stored in the memory can include the derived data, as well as the original data and actual data values ​​obtained based on the data collected by the onboard subsystem.

[0072] The established mapping relationship can reflect the raw data, actual data values, and derived data for a specific spatial location in a train car. The raw data, actual data values, and derived data for all spatial locations corresponding to each train car are tagged with the train's physical location, resulting in a full data package. Specifically, the full data package can be encapsulated as a fixed-structure data list, such as in JSON / XML format, to unify the data format for easier transmission and parsing.

[0073] The train data real-time transmission and processing method further includes:

[0074] If it is detected that the train topology information changes, updating the mapping relationship;

[0075] A full data packet marked with the physical location of the train is generated based on the updated mapping relationship.

[0076] To cope with dynamic changes in the topology structure (such as train formation adjustments), a topology change monitoring module can be set up. When a topology change is detected, the data location remapping process is automatically triggered, that is, the mapping relationship is updated to ensure accurate correspondence between data and physical locations, which facilitates subsequent tracing and analysis.

[0077] In step S3, the handheld terminal server sends the full data packet to the handheld mobile terminal, which then performs a second data processing on the full data packet and displays the processed terminal data. A communication bridge is established between the handheld terminal server and the handheld mobile terminal via the onboard WiFi network. The handheld terminal server establishes an HTTP / WebSocket connection with the handheld mobile terminal via a wireless access point (AP) and a firewall. When the handheld mobile terminal requests specific page data, the handheld terminal server responds by transmitting a full data packet tagged with the train's physical location, enabling wireless data transmission from the onboard device to the terminal.

[0078] The handheld mobile terminal performs a second data processing on the full data packet and displays the processed terminal data, including:

[0079] The full data packet is verified, the state of the verified full data packet is converted, and the processed terminal data is obtained and displayed. After the handheld mobile terminal receives the full data packet, it first performs data decryption and integrity verification to ensure that the data has not been tampered with. Then the data conversion is completed through visual dictionary matching. Based on the pre-built visual mapping dictionary, the addition of units (such as ℃, kPa), corresponding text mapping (such as "0" corresponds to "normal", "1" corresponds to "fault"), corresponding image display (such as "0" corresponds to green, "1" corresponds to red) and other processing are realized, and finally displayed in real time through the App interface.

[0080] After the step of obtaining and displaying the processed terminal data, the method for real-time transmission and processing of train data further includes:

[0081] Processed terminal data is monitored and an alarm message is generated if abnormal data is detected. The app supports fault alarm push notifications. When abnormal data is detected, the fault location is automatically highlighted and a solution is provided. The app receives fault data in real time and displays the specific cause of the fault and solution suggestions by matching it with the app's fault dictionary.

[0082] The system for implementing the real-time transmission and processing method of train data mainly consists of the following parts:

[0083] TCMS data acquisition equipment, namely the handheld terminal server: used to collect various train operation data and monitor the train status in real time through sensors.

[0084] On-board WiFi network: provides wireless communication channels for data transmission, ensuring that TCMS data can be transmitted to handheld mobile terminals in a timely manner.

[0085] Handheld mobile terminal: such as a smartphone or tablet computer, through which operators view TCMS data in real time.

[0086] App: Installed on a handheld mobile terminal, it receives and displays TCMS data and supports fault warning and diagnosis functions.

[0087] Data transmission module: ensures stable data transmission between TCMS data acquisition equipment and handheld mobile terminals.

[0088] Through this system architecture, all train status data is transmitted to handheld mobile terminals via a wireless network, allowing operators to view, analyze, and diagnose train operating conditions at any time. This system not only improves the real-time nature of train operation monitoring but also significantly enhances fault response capabilities and maintenance efficiency.

[0089] The specific implementation of the method is briefly described as follows:

[0090] 1. The TCMS data acquisition equipment in the train collects the train's operating status data in real time and

[0091] The WiFi module converts the data into standard data packets that can be transmitted.

[0092] 2. The onboard Wi-Fi network receives the data and sends it to the train's handheld mobile terminal, which receives and displays the data in real time via an app.

[0093] 3. Operators use handheld mobile terminals to view data and can check the train operation status at any time in the carriage, equipment site and other areas.

[0094] 4. When a train malfunction occurs, the TCMS data acquisition device will identify the anomaly and transmit the fault information to the handheld mobile terminal via the WiFi network. The App will push the fault alert in real time.

[0095] 5. The app can also provide fault location, diagnostic suggestions and operation steps based on the fault type to help operators quickly resolve the problem.

[0096] The method for real-time transmission and processing of train data provided by the embodiment of the present invention has the following functions:

[0097] 1. Wireless data transmission: Traditional TCMS data relies on wired or limited-range wireless connections, while the present invention provides vehicle-wide wireless data transmission through onboard WiFi, eliminating the need for operators to be confined to a fixed location.

[0098] 2. Handheld mobile terminal display: The present invention provides a convenient data viewing and operation method through a handheld mobile terminal, breaking the limitation of fixed equipment and improving the flexibility of operation and instant feedback.

[0099] 3. Intelligent diagnostic function: Through the intelligent fault diagnosis and early warning functions provided by the App, operators can locate and handle faults more efficiently, reduce fault response time, and improve train operation safety.

[0100] The real-time transmission and processing method for train data provided by an embodiment of the present invention installs a TCMS data acquisition device on the train and uses the on-board WiFi to transmit the data in real time to a handheld mobile terminal. Operators can view the train's operating status in real time at any location on the train, especially at the equipment site, thereby improving work efficiency and fault response speed. This breaks the traditional TCMS system's dependence on space and solves the limitation that mechanics or other staff can only view data in a fixed area.

[0101] The method for real-time transmission and processing of train data provided by the embodiment of the present invention has the following beneficial technical effects:

[0102] 1. Improved flexibility of train operation monitoring:

[0103] Traditional train TCMS systems typically display train operation data through fixed display devices (such as in the driver's cab and mechanic's room), and operators can only view data in specific areas. This limitation results in low efficiency in troubleshooting and daily monitoring. However, the present invention receives and displays TCMS data through handheld mobile terminals (such as smartphones and tablets), allowing operators to view train status information in real time from within the train car, at the equipment site, or anywhere else they need to check, greatly improving work flexibility.

[0104] 2. Enhanced fault response capabilities:

[0105] When a train malfunctions, traditional TCMS systems can only generate alarms through fixed equipment, and operators may not be able to immediately identify and locate the fault. This can lead to delayed fault handling and increase the scope of the fault's impact. With this invention, fault information can be instantly pushed to the operator's handheld mobile terminal, allowing the operator to quickly view the fault location, type, and possible causes. The fault diagnosis function in the app also provides operational guidance and handling suggestions to help operators locate the problem as quickly as possible and take effective measures, shortening fault response time and improving the safety and reliability of the train.

[0106] 3. Improved train maintenance and management efficiency:

[0107] Using handheld mobile terminals, operators can access real-time train status data anytime and anywhere, facilitating inspection, maintenance, and management. Mechanics no longer need to be confined to a fixed work area and can perform equipment inspections and troubleshooting from multiple locations, including on-site and inside train cars. This flexibility effectively avoids the traditional inefficient collaboration model of "one operator operating, another monitoring," improving work efficiency and collaboration. For routine maintenance and troubleshooting, operators can immediately access real-time data, reducing unnecessary travel and wasted time.

[0108] 4. Reduce human errors and operational difficulties:

[0109] Traditional TCMS system displays typically only provide data and alerts, and during operation, operators rely on their familiarity with traditional equipment and their memory to make quick decisions. This can lead to problems caused by information lag, misoperation, or data errors. However, the smart app of the present invention provides real-time data updates and clear fault guidance, reducing the risk of human error. Through the intelligent interface, operators can quickly obtain the cause of the fault and the solution, greatly reducing operational difficulty and enabling rapid response, especially in emergency situations.

[0110] 5. Realize intelligent fault warning and diagnosis:

[0111] The handheld mobile terminal of this invention not only displays real-time train status data but also provides fault warning and diagnostic capabilities. The system monitors train operation in real time. If a potential fault is detected, the handheld mobile terminal promptly issues a fault alert, accurately indicating the fault type and location, and providing possible solutions. This intelligent functionality allows operators to receive early warnings of problems, preventing them from worsening or spreading due to delayed information. This technological advantage contributes to improving the safety and reliability of train operations.

[0112] 6. Reduced maintenance costs:

[0113] Traditional TCMS systems rely on multiple fixed terminals and complex hardware, resulting in high maintenance costs and lengthy fault detection and troubleshooting cycles. In contrast, the wireless data transmission and intelligent terminal system of the present invention significantly simplifies hardware configuration and maintenance. Because data transmission is performed via WiFi, operators only need to use standard intelligent terminal devices, rather than relying on specialized, expensive displays or equipment, thus reducing system deployment and maintenance costs. Furthermore, intelligent diagnostic capabilities help operators locate and repair problems more quickly, reducing downtime caused by faults and further reducing train operating costs.

[0114] 7. Improved train safety:

[0115] By acquiring real-time information about various train statuses, operators can quickly understand the train's operating status, identify potential safety hazards, and take prompt action. This invention provides timely warnings and rapid responses to potential train accidents, such as traction system failures and braking system issues. Through instant data transmission and intelligent diagnostics, the system helps operators take more precise measures, significantly improving train safety and stability.

[0116] 8. Strong scalability and adaptability:

[0117] The system architecture of this invention is highly scalable, allowing for the addition of more handheld mobile terminals and adaption to different vehicle models and train systems as needed. With the widespread adoption of onboard Wi-Fi and smart terminal devices, this invention can be applied to a wide variety of train types. With future technological advancements and equipment upgrades, system performance and intelligence will be further enhanced.

[0118] 9. User-friendliness and easy operation:

[0119] The smart app's design prioritizes user experience, offering an intuitive interface and simple operation. Even operators with non-technical backgrounds can quickly master the app and understand train operating status and fault information, reducing operational complexity. Furthermore, the app supports personalized settings, allowing operators to customize the display interface and data content to best serve different scenarios and needs.

[0120] The real-time transmission and processing method of train data provided by an embodiment of the present invention comprises the following steps: a handheld terminal server receives TRDP data sent by an on-board subsystem, parses the TRDP data, and obtains data collected by the on-board subsystem; the handheld terminal server performs a first data processing on the data collected by the on-board subsystem to obtain derived data; a full data packet marked with the physical location of the train is generated based on the pre-acquired train topology information, the on-board subsystem collected data, and the derived data; the handheld terminal server sends the full data packet to a handheld mobile terminal, so that the handheld mobile terminal performs a second data processing on the full data packet, and displays the processed terminal data, so as to be able to transmit real-time monitoring data to the handheld mobile terminal, thereby improving operational flexibility and response speed.

[0121] Furthermore, the handheld terminal server performs a first data processing on the data collected by the vehicle-mounted subsystem to obtain derived data, including:
