[0032] The present application further provides an on-vehicle data interaction management system including the on-vehicle data processing device described above. The system further includes a ground server, and the ground server is configured to receive the data provided by the data transceiver unit through a preset interface; and obtain the monitoring data of the infrastructure and the external environment of the on-vehicle data interaction management system; wherein, the monitoring data of the infrastructure includes the monitoring data of one or more of TPDS, tunnels, power supply workers, bridges, and operation lines; the monitoring data of the external environment includes the monitoring data of one or more of foreign object intrusion, natural disasters, and geological disasters.

[0033] Specifically, in actual work, the vehicle-mounted data interaction management system can be implemented through a vehicle-mounted network data center system, which consists of three components: the vehicle-mounted control network, the vehicle-mounted data platform, and the vehicle-mounted monitoring network.

[0034] The main functions of the vehicle-mounted control network are as follows:

[0035] (1) Undertake the monitoring, control, and diagnosis tasks of train operation, which are oriented to train-related systems (traction, braking, high voltage, doors...).

[0036] (2) Monitor the key components and operating status of the train, and give early warnings and alarms (bogie instability, bearing temperature and diagnosis, carbody stability, fire protection, high voltage...).

[0037] (3) Receive train operation instructions (traction, braking) and relevant train operation status information (tunnel, kilometer marker...) from third-party devices ATP / ATO.

[0038] For the vehicle-mounted monitoring network, compared with existing EMUs, the main monitoring functions are as follows:

[0039] (1) Connect to the PIS system and conduct data interaction with the PIS system under the condition of setting up a firewall.

[0040] (2) Receive relevant EMU video information such as car video, pantograph video, and auxiliary lookout video.

[0041] (3) Receive relevant life information and power supply status information of third-party devices (ATO / ATP / EOAS / DMS / CIR / WTP / earthquake warning / over-the-horizon).

[0042] The function of the vehicle-mounted monitoring network is to transfer video data with large capacity and low real-time requirements, such as car video / pantograph video, from the PIS network to the monitoring network, restore the passenger service function that originally belonged to the PIS system, and expand other in-vehicle monitoring requirements (such as auxiliary lookout video / third-party devices).

[0043] For the vehicle-mounted data platform, its main load is to receive and store data, specifically including the following categories:

[0044] (1) Receive and store relevant data information on the monitoring, control, and diagnosis of the operation of the vehicle-mounted control network.

[0045] (2) Receive and store relevant data information of PIS / video / third-party devices from the vehicle-mounted monitoring network.

[0046] (3) Under the condition of setting up a firewall, transmit relevant data information to the ground system through wireless mobile communication means such as 5G / WLAN.

[0047] (4) Under the condition of setting up a firewall, through the WTP device, receive data information of infrastructure (TPDS / bridge / tunnel / operating line) and external environment (foreign object intrusion / wind, rain, snow / debris flow) from the ground server.

[0048] (5) Receive vehicle-mounted positioning information (firewall) and relevant data of EOAS (train number, train control equipment clock, running speed, kilometer post, braking state) from the Beidou system.

[0049] The vehicle-mounted data platform also needs to perform analysis and processing, and its functions include the following:

[0050] (1) In existing EMUs, Beidou data and ground system-related data are directly connected to the control network through wireless networks (satellite communication / 5G / WLAN). In the system design of the new-generation Fuxing EMU, the vehicle-mounted data platform isolates and stores Beidou data and ground system data, avoiding the risk of external data directly attacking the vehicle-mounted control network and ensuring the safe operation of the train.

[0051] (2) In existing EMUs, the vehicle-mounted control network needs to call relevant video data of the EMU (carriage video / pantograph video) through the PIS network when necessary. Most of the data in the monitoring network is video monitoring data, so the data volume is large. In addition, there are many types of monitoring data in the monitoring network, so they are combined into a monitoring network and uniformly managed by the vehicle-mounted data platform. In the system design of the new-generation Fuxing EMU, the control network data and the monitoring network data are isolated and managed to prevent relevant video data from flowing into the vehicle-mounted control network and occupying a large amount of bandwidth, ensuring the reliability of the control network operation.

[0052] (3) In existing EMUs, infrastructure data and external environment data connected to the ground server do not access the EMU system. In the system design of the new-generation Fuxing EMU, expand the external data requirements, connect infrastructure and external environment-related data information to the vehicle-mounted data platform of the EMU, and assist the EMU in health management and safety operation guarantee.

[0053] (4) Conduct train-level comprehensive diagnosis, mainly including the following aspects:

[0054] 1) Train operation evaluation: During the operation of the EMU, the vehicle-mounted data center integrates public information such as kilometer posts and road conditions obtained from the control network, monitoring network, and EOAS, as well as information related to functional subsystems such as traction and braking, and uses analysis methods such as multi-system correlation and multi-train comparison for comprehensive diagnosis, and further gives train operation evaluation results and emergency disposal suggestions to assist the driver and the mechanic in emergency handling.

[0055] After each round-trip operation of the multiple unit train, the operation of this round-trip is evaluated, and an operation report for this round-trip is automatically generated, providing data support for the next round-trip operation or depot maintenance of the multiple unit train, and at the same time enabling the driver to quickly understand the operation conditions of this round-trip.

[0056] 2) Full train comparison and analysis: During the train operation, important historical parameters of each car of the whole train are compared and analyzed in real time according to the correlation; early anomalies are detected through the full train comparison, and early warning prompts are given before the subsystem alarms, providing support for the mechanic during train operation. The horizontal comparison mode of the whole train subsystems is shown in Table 1 as follows:

[0057] Table 1

[0058]

[0059]

[0060]

[0061]

[0062]

[0063] 3) Data curve playback: Provide parameter curve playback of various monitoring data for the crew. When an alarm occurs, it assists the mechanic to confirm the accuracy of the alarm; when a fault occurs, it enables the mechanic to quickly understand the historical state and deterioration trend of the equipment.

[0064] 4) Component load analysis: Component load analysis is statistically carried out based on the sensor data and operation status data of the monitoring network and control network. It is mainly divided into two major types of loads. The first type is the component action frequency load, and the second type is the component working duration load; it supports querying of load data, and also supports horizontal comparison of multiple cars and trend analysis of multiple round-trips. When the component load exceeds the normal level, it prompts the mechanic to pay attention.

[0065] 5) Historical comparison and analysis: Based on the output results of the intelligent equipment of the multiple unit train, continuous cumulative calculations are carried out on the state parameters of each important subsystem. When the component performance deteriorates to affect the operation safety, it prompts the mechanic to pay attention and handle it.

[0066] (5) Use the multi-source data information collected by the system (subsystem parameters, key component parameters, video data, operation status of third-party equipment, infrastructure data, external environment data) for in-depth train fault diagnosis and health assessment. For example: diagnose wheel wear or polygon through collecting information related to the operation line (such as rail corrugation).

Since the above vehicle-mounted data processing method has been described and exemplified one by one in the foregoing embodiments, it will not be elaborated here one by one.
