Description

Technical Field

[0001] The present disclosure relates to the field of rail transportation technology, and in particular to a health management system, equipment, and train for a train communication network. Background Art

[0002] Due to the dramatic increase in data volume in train communications, traditional train buses are unable to meet the requirements for large data transmission. Compared with traditional train buses, Ethernet communication networks have advantages such as low price, high speed, and large data volume. They can meet the data transmission requirements of operations such as on-board broadcast systems, video systems, and firmware downloads. Therefore, Ethernet communication networks are now widely used for train communications.

[0003] In existing technologies, health management solutions for Ethernet communication networks typically store fault data in a central control unit (CCU), which is then transmitted to a ground server via a wireless transceiver. The data is then processed by a health management algorithm within the ground server. This requires staff to wait for the ground server to analyze the fault data before understanding the specific health status of the Ethernet communication, wasting significant time. Furthermore, to avoid the additional bus and wireless bandwidth consumed during the transmission of fault data to the CCU, existing technologies only store and transmit critical fault data to the ground server, resulting in incomplete recording and analysis of Ethernet communication faults.

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below with reference to the accompanying drawings.

[0022] Figure 1 A structural diagram of a train communication network health management system provided by an embodiment of the present disclosure is shown as follows: Figure 1 As shown, the health management system includes: a health management module 100 and a monitoring module 200, the monitoring module 200 is communicatively connected to the health management module 100; the health management module 100 is set in the train and has a built-in health management algorithm; the health management module 100 is used to obtain the health status of the train communication network 300; the monitoring module 200 is set in the ground server for monitoring the health status.

[0023] Specifically, the health management module 100 uses a health management algorithm to obtain the health status of the train communication network 300 and transmits the health status of the train communication network 300 to the monitoring module 200 via wireless transmission. Staff can then monitor the health status of the train communication network 300 via the monitoring module 200 located in the ground server. Therefore, the health management module 100 does not need to send health-related information about the train communication network 300 to the central control unit, which then sends the relevant information to the ground server. Instead, the health management module 100 interacts directly with the monitoring module 200 via wireless transmission, thus eliminating the need for additional bus and wireless bandwidth usage.

[0024] The health management module 100 includes a message acquisition unit 110 and a health management unit 120; the message acquisition unit 110 is communicatively connected to the train communication network 300, and the message acquisition unit 110 is also communicatively connected to the health management unit 120, and the health management unit 120 is communicatively connected to the monitoring module 200; the message acquisition unit 110 is used to obtain messages from the train communication network 300 at every moment, and the health management unit 120 is used to obtain data information of the message, determine health information based on the data information and the health management algorithm, and determine the health status based on the health information; wherein the data information is data on the actual working status of the train communication network 300, the health management algorithm is an algorithm for obtaining health information based on health standards, the health standard is the value range of the data information when the train communication network 300 is working normally, and the health information is information reflecting the health status of the train communication network 300.

[0025] For example, the message acquisition unit 110 can be a switch ring network, which acquires messages from the train communication network 300. The health management unit 120 extracts the messages from the message acquisition unit 110 using embedded software, enabling real-time reception, processing, and timestamping of the messages. The health management unit 120 also processes the messages by applying methods such as sorting, deduplication, and statistics to obtain message data information, and monitors the message status, including identifying service enablement for the messages and determining whether interference exists.

[0026] Exemplarily, the data information of the message may be, for example, the invalid message occupancy rate of the train communication network 300. The number of invalid messages in the train communication network 300 is detected according to the TRDP protocol and the invalid message occupancy rate is obtained. The health information of the train communication network 300 is determined based on the comparison result of the invalid message occupancy rate and the occupancy rate threshold.

[0027] Exemplarily, the data information of the message may be, for example, the frame loss rate of the message. The health management unit 120 analyzes, for example, 328 messages obtained, passes the obtained messages through the attribute matrix, and then sorts all the messages according to the acquisition time of the messages. The message loss is then calculated in the sorted order to obtain the frame loss rate, frame loss trend, and frequency of frame loss of the messages. Finally, the health information of the train communication network 300 is determined based on the normalized threshold behavior.

[0028] Exemplarily, the data information of the message may be, for example, the frame loss behavior of the message. The health management unit 120 analyzes, for example, 328 messages obtained, passes the obtained messages through the attribute matrix, and then sorts all the messages according to the acquisition time of the messages, and then calculates the frame loss of the messages in the sorted order. In the frame loss calculation process, the weight of continuous frame loss is increased, and the vital signal stagnation is included in the analysis. The frame loss behavior is determined based on the frame loss rate of the message, the maximum continuous frame loss, and the vital signal stagnation calculation, and the health information of the train communication network 300 is determined according to the frame loss behavior of the message.

[0029] For example, the data information of a message can be, for example, the cyclic stability of the message. The health management unit 120 analyzes, for example, 328 acquired messages, ignoring the effects of message frame loss and message duplication. The acquired messages are sorted according to their acquisition time after passing through an attribute matrix. A statistical algorithm is applied to each sorted message, and packet loss calculation is performed. Finally, interference is eliminated based on the statistical parameters obtained by the statistical algorithm. A hypothesis test method with high robustness is used to determine the cyclic jitter of the message. The cyclic jitter of the message is compared with a preset cyclic jitter threshold. The cyclic stability of the message is determined based on the comparison result, and the health information of the train communication network 300 is determined based on the cyclic stability.

[0030] It should be noted that the data information of the message includes invalid message occupancy rate, frame loss rate, frame loss behavior and periodic stability. The number of messages is 328 and is just an example. The specific data information and the number of messages need to be set according to actual conditions and are not specifically limited here.

[0031] Specifically, the message acquisition unit 110 packages and extracts the messages generated by the train communication network 300 at each moment, and sends the packaged messages to the health management unit 120. The health management unit 120 analyzes the acquired messages, extracts the data information from the messages, and obtains health information reflecting the health status of the train communication network 300 based on the data information and the health management algorithm. The messages contain multiple different data information, each of which can reflect a fault condition of the train communication network 300. Therefore, corresponding health information is obtained based on each data information, and the health status of the train communication network 300 can be determined based on the multiple health information. When the number of health information indicating that a piece of data information is faulty is greater than or equal to a number threshold, the health status of the train communication network 300 is determined to be faulty; when the number of health information indicating that a piece of data information is faulty is less than the number threshold, the health status of the train communication network 300 is determined to be healthy.

[0032] The health management module 100 sends the generated health status to the monitoring module 200. The monitoring module 200 is located in the ground server, so that staff can monitor the health status of the train communication network 300 through the ground server. Thus, the present disclosure uses the health management algorithm located in the health management module 100 to obtain the health status of the train communication network 300 in real time based on the data information in the train communication network messages obtained in real time. The monitoring module 200 located in the ground server can directly obtain the health status of the train communication network. Therefore, staff do not need to wait for the ground server to obtain the message data information and then calculate and analyze the health status of the train communication network 300. Instead, they can directly monitor the health status of the train communication network 300 through the ground server, saving waiting time. Furthermore, the monitoring module 200 can directly monitor the health status corresponding to all messages obtained by the health management module 100 at all times, making the record of the communication network health status more comprehensive. In addition, since the data information does not need to be transmitted to the central control unit, there is no additional bus and wireless bandwidth usage.

[0033] In some embodiments, the health management module further includes a storage unit; the storage unit is communicatively connected to the health management unit, and the storage unit is used to store health information of the train communication network at every moment.

[0034] Specifically, the storage unit stores multiple pieces of health information corresponding to each message in the train communication network at each moment, as well as the data information corresponding to each message. This allows historical data to be directly retrieved from the storage unit when needed. This improves the extraction of historical health data of the train communication network, and the storage unit stores the health status corresponding to messages at all times, providing a more comprehensive record of the communication network's health.

[0035] In some embodiments, the health management module also includes a health assessment unit; the health assessment unit is communicatively connected to the health management unit and the storage unit respectively; the health assessment unit is used to obtain the current health information determined by the health management unit, and to obtain the historical health information group stored in the storage unit; and is used to obtain the current health status of the train communication network based on the current health information, and to infer the future health status of the train communication network based on the association relationship of the historical health information group; wherein the current health information is the health information of the train communication network at the current moment, and the historical health information group includes the health information of the train communication network at each historical moment; the association relationship is the association relationship between the health information at each historical moment.

[0036] Specifically, the health assessment unit is in communication with the health management unit. After the health management unit obtains various pieces of health information corresponding to the current messages of the train communication network, the health assessment unit obtains the current pieces of health information, determines whether the data corresponding to each piece of health information is faulty or healthy, and finally compares the number of health information indicating faulty data with a threshold value. When the number of health information indicating faulty data is greater than or equal to the threshold value, the health status of the train communication network is determined to be faulty; when the number of health information indicating faulty data is less than the threshold value, the health status of the train communication network is determined to be healthy.

[0037] Exemplarily, the health assessment unit is also communicatively connected to the storage unit, and the health assessment unit can extract the historical health information group stored in the storage unit. The historical health information group includes various health information corresponding to the messages of the train communication network at each historical moment. By arranging and comparing the data information corresponding to each health information, the corresponding correlation relationship can be obtained. For example, at each historical moment, the frame loss rate of the message shows a gradually increasing trend, and in the health information corresponding to the frame loss rate of the message, the number of health information reflecting that the frame loss rate of the message is higher than the frame loss rate threshold increases and is continuous. Therefore, it can be considered that the health information about the data information of the frame loss rate of the message shows a trend of failure. When the number of health information showing a trend of failure or a failure that has occurred in each health information is greater than the quantity threshold, the future health condition of the train communication network is considered to be a failure. The trend of failure can be judged according to the following formula. The merged group formula of the sample size is N1+N2, and the merged group formula of the mean is The combined group formula for standard deviation is:

[0038]

[0039] Among them, N1 is the sample size at the current moment, N2 is the sample size at the previous moment, M1 is the mean at the current moment, M2 is the mean at the previous moment, SD1 is the standard deviation at the current moment, and SD2 is the standard deviation at the previous moment.

[0040] Therefore, through the present disclosure, staff can obtain information about current and future faults in the train communication network, thereby avoiding communication problems caused by faults.

[0041] In some embodiments, the health management module further includes an alarm unit; the alarm unit is communicatively connected to the health assessment unit; the alarm unit is configured to issue an alarm based on abnormalities in the current health condition and to issue a warning based on abnormalities in the future health condition.

[0042] Specifically, the alarm unit can issue an alarm based on the health assessment unit's assessment of the train communication network's health. When the health assessment unit determines that a fault has occurred in the train communication network, the alarm unit alerts personnel to the current fault. When the health assessment unit determines that a fault will occur at some point in the future, the alarm unit issues a warning signal to personnel regarding the impending fault. Furthermore, because each message originates from communication network equipment at different locations on the train, the health assessment unit can also determine the location of the faulty message based on the location information within the message. The alarm unit can then use this location information to notify personnel of the specific fault location, facilitating their ability to locate the fault and improving the efficiency of repairing train communication network faults.

[0043] In some embodiments, the health management unit includes an address detection component; the address detection component is used to obtain current network address information of the current message, and determine health information based on the current network address information and the health management algorithm.

[0044] Exemplarily, the health management algorithm is, for example, to compare current network address information with historical network address information. The address detection component is in communication with a storage unit, and the address detection component can obtain historical network address information stored in the storage unit. The historical network address information is the network address information of a message that has undergone address detection. The current network address information can be, for example, the current IP address. The address detection component obtains the current IP address of the current message and extracts the historical IP addresses through the storage unit. The address detection component compares the current IP address with each historical IP address. If the comparison result shows that the current IP address and the historical IP address do not have duplicate IP addresses, the train communication network is considered to have IP address integrity. If the comparison result shows that the current IP address and the historical IP address have duplicate IP addresses, the train communication network is considered to have an IP address conflict problem.

[0045] The current network address information can be, for example, the current MAC address. The address detection component obtains the current MAC address of the current message and extracts the historical MAC addresses from the storage unit. The address detection component compares the current MAC address with each historical MAC address. If the comparison result shows that the current MAC address and the historical MAC addresses do not have duplicate MAC addresses, it is considered that the MAC addresses of the train communication network do not conflict. If the comparison result shows that the current MAC address and the historical MAC addresses have duplicate MAC addresses, it is considered that there is a MAC address conflict problem in the train communication network.

[0046] It should be noted that the network address information being an IP address or a MAC address is only an example, and the specific network address information is set according to actual conditions and is not specifically limited here.

[0047] In some embodiments, the health management unit includes a port detection component; the port detection component is used to obtain physical interface information of the train communication network, and determine health information based on the physical interface information and the health management algorithm.

[0048] For example, physical interface information can be bandwidth load ratio. The port detection component analyzes, for example, 640 acquired messages and 320 physical interfaces. After multicasting and counting the acquired messages according to the message acquisition module information through an attribute matrix, the physical interface is enabled and load parameters are obtained through statistical analysis. The statistical analysis considers the traffic and jitter of the physical interface and calculates the bandwidth load ratio based on the acquired load parameters. The bandwidth load ratio is compared with a preset load ratio threshold, and the health of the train communication network is determined based on the comparison result.

[0049] Physical interface information can be, for example, the packet error rate (ERR). The port detection component analyzes 320 physical interfaces, passes the obtained messages through an attribute matrix, multicasts and counts them according to the message acquisition module information, enables and sorts the physical interfaces, and calculates packet error statistics by calculating the mean, variance, and rate of change. The false alarm rate is then calculated based on the filtering parameters and the ERR. The packet error rate is compared with a pre-set packet error rate threshold, and the health of the train communication network is determined based on the comparison result.

[0050] The physical interface information can be, for example, the connection status of the physical interface. After the obtained message is passed through the attribute matrix and the module information multicast count is obtained according to the message, the physical interface is enabled and sorted. The characteristic parameters of the connection status are calculated by the previous state, interruption time, recovery time and current state duration. After eliminating interference, the characteristic parameters of the connection status are judged to determine the connection status of the physical interface, and the health information of the train communication network is determined based on the connection status.

[0051] It should be noted that the physical interface information, such as the bandwidth load rate, the packet error rate, and the connection status of the physical interface, are all examples. The specific physical interface information is set according to actual conditions and is not specifically limited here.

[0052] In some embodiments, the health management system also includes a health management host; the health management host is communicatively connected to the health management module, and the health management host is used to generate processing requirements for the train communication network based on health information; wherein the processing requirements are requirements for processing the health status of the train communication network.

[0053] Specifically, the health management host may store the health status of the train communication network obtained by the health management module, and determine whether related equipment of the train communication network needs maintenance based on the stored health status.

[0054] In some embodiments, the health management system further includes a wireless transceiver, and the health management module is communicatively connected to the monitoring module via the wireless transceiver; the wireless transceiver is used to send the health status generated by the health management module to the monitoring module.

[0055] Specifically, the health management module acquires the health status of the train communication network and transmits it to the monitoring module via wireless transmission via a wireless transceiver. Staff can then monitor the health of the train communication network via the monitoring module located in the ground server. This eliminates the need for the health management module to transmit information related to the train communication network's health to the central control unit, which then transmits the relevant information to the ground server. Instead, the health management module interacts directly with the monitoring module via wireless transmission via a wireless device, eliminating the need for additional bus and wireless bandwidth usage.

[0056] The present disclosure also provides a health management device for a train communication network, including any of the above health management systems.

The main control board 420 is used to receive the operation information and fault information of the train communication network from the communication board 440, and is responsible for the calculation and processing of the health management module. The health status of the train communication network obtained after processing is transmitted to the train communication network through the transmission board 450, and then the health status is wirelessly transmitted to the ground equipment through the wireless transceiver. In addition, the main control board 420 will transmit the health status of the train communication network and data information with a large amount of data to the storage board 430 through the transmission board 450 for subsequent use. The communication board 440 is responsible for receiving messages from the message acquisition unit and performing preliminary processing of each message using the health management algorithm. The processed information is then transmitted to the main control board 420 via the communication board 440 .
