Its safe and stable operation is related to the safety and efficiency of railway transportation. In actual operation, the on-board ATP has the function of diagnosing and recording the equipment operation status, which will record the relevant status information of the equipment and train operation for subsequent analysis, which is of great significance to the troubleshooting, prevention and analysis of on-board ATP equipment.

[0003] The safety computer board of the ATP on-board equipment records the equipment operating status in the form of detailed train operation data and summary abnormal fault data.

[0060] For further information, see Figure 2 As shown, the on-board data recording unit is provided with a power supply unit, a network communication unit, a locomotive signal processing unit, a storage unit, an RTC clock unit, and a processor;

[0061] The power supply unit is used to control and protect the external power input. The external power supply includes the front panel power input and the back panel power input, which provide working power for each unit of the vehicle data recording unit;

[0071] The on-board data recording unit realizes the complete recording and storage of ATP train operation data, balise transmission module BTM operation data, locomotive signal data, Ethernet forwarding, USB port dumping and other functions, while ensuring good safety isolation without affecting the ATP control function.

[0072] The on-board data recording unit communicates with the safety computer of the ATP on-board equipment, completely dumps the detailed train operation data and abnormal fault summary data in the safety computer, and parses and integrates them to generate new types of data and record them, and the recorded content is no less than the original content.

[0073] The ground server receives and stores data from the vehicle data recording unit transmitted through the vehicle transmission system communication channel, and provides access and download services to the analysis client. At the same time, the server provides a data access interface for the vehicle equipment management information system (AMIS).

[0074] Specifically, the vehicle-mounted data recording unit implements a recording method, the method comprising:

[0075] Monitor and receive train operation data from the ATP host, and store it in sections and partitions according to the specified data file storage format;

[0076] Analyze the operation data to extract key parameters and store them in DTL type;

[0077] Receive and store BTM host data;

[0078] Receive and store locomotive signal raw waveform data.

[0079] In a specific embodiment, the train control vehicle-mounted equipment operation data transmission process is as follows: Figure 3 As shown, the specific data transmission process is as follows:

[0080] S301: The on-board data recording unit receives and records the ATP on-board equipment operation data, BTM operation data and locomotive signal waveform data sent by ATP and BTM through Ethernet, and stores them in segments and partitions according to the specified data file storage format. When ATP data is received, it is first stored in segments, and the recorded data is divided into blocks. The data header of each block records the description information of the block data, such as the recording date, to facilitate data retrieval;

[0081] S302: The vehicle data recording unit is connected to the vehicle transmission system via Ethernet, and the data to be sent is packaged according to the transmission protocol specified by the vehicle transmission system;

[0082] S303: The vehicle-mounted data recording unit sends the data to the ground server via the mobile communication network of the vehicle-mounted transmission system through the TCP protocol;

[0083] S304: The ground server is responsible for receiving the communication request of the vehicle-mounted data recording unit and the data receiving, processing and storing tasks. At the same time, the ground server is connected with multiple clients through the railway internal office network;

[0084] S305: The user can access and download the data in the ground server through the data analysis client or the vehicle-mounted equipment management information system.

[0085] In a specific embodiment, see Figure 4 As shown, for the stability of data transmission, the vehicle data recording unit needs to establish a stable connection with the vehicle transmission system. The data transmission process is as follows:

[0086] S401: The device is connected to the MITS vehicle monitoring information integrated transmission system via Ethernet. After the device is turned on, it needs to shake hands with MITS. The device sends a registration request to MITS. After the sending is completed, it waits for the response from MITS. When the registration success message is received, the registration is completed. If the registration fails or there is no response for more than 10S, the device will send a registration request to MITS again and prompt that the registration failed or timed out:

[0087] S402: When data needs to be sent, the device performs the first step of packet assembly according to the type of data to be sent, the data length, etc. After the first step of packet assembly is completed, the second step of packet assembly is performed according to the transmission protocol specified by MITS;

[0088] S403: After the package is assembled, the device uploads the data to the server through the MITS channel via the TCP protocol. After the data is sent, the MITS response is received within 1S to complete the data sending;

[0089] S404: When the data transmission does not receive a response from MITS within 1 second, the data is resent.

[0090] Correspondingly, while receiving data, the ground server also needs to regularly query whether there are new real-time records to be sent in order to ensure the integrity of data transmission, such as Figure 5 As shown, the communication forwarding module in the ground server software periodically calls the interface to query whether there are real-time records to be sent. If so, it will be sent; after receiving the MITS package response, it can immediately query whether there are real-time records to be sent. If so, it will continue to send; otherwise, it enters the scheduled processing flow.

[0091] Further, the analysis client is provided with client analysis software;

[0092] The client analysis software manages the users’ rights in different levels according to the bureau, section and workshop. When downloading data, the users must log in for identity authentication.

[0093] The client analysis software filters and displays the data according to time, vehicle number, and data type conditions;

[0094] The client analysis software performs intelligent analysis of vehicle-mounted data in real time, detects the status of ATP vehicle-mounted equipment, parses detailed operating information of ATP vehicle-mounted equipment, feedbacks and analyzes fault information, and provides disposal suggestions.

[0095] In a specific embodiment, see Figure 6 As shown, the present invention also discloses a train operation data analysis software, including the following functions:

[0096] File processing: It can be indexed by time, file type and other conditions to realize wireless real-time download of train operation data, BTM data and other files, manual file import, and file segmentation by conditions;

[0097] Analysis business: Analyze the data and display the equipment status information, operation control information, subsystem information, message analysis and other contents in the form of graphs, curves, lists, etc. At the same time, alarm the abnormal data based on historical big data and expert experience, intelligently analyze the abnormal causes, and provide disposal suggestions;

[0098] Software configuration: Configuration management of software usage permissions and versions, including personnel permissions, user units, vehicles under management, etc.
