Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of heavy-load train status monitoring, and in particular to a method, device, equipment, medium and program for on-board status monitoring of a heavy-load train. Background Art
[0002] The on-board ATP equipment (Automatic Train Protection) used in the heavy-haul train control system is based on the technology of large-haul railways and is upgraded in combination with the signal characteristics of heavy-haul railways. The on-board equipment of large-haul railways has more than 10 years of operating experience and is safe and reliable. However, due to the weak accumulation of signal experience, heavy-haul railways use speed sensors, Beidou satellites and other technologies to fuse and process multi-source data to achieve accurate train positioning. According to the train parameters and the track circuit information, line data and temporary speed limit sent by the ground equipment, control curves are generated according to the target-distance mode to monitor the safe operation of the train. How to ensure the safety and reliability of its operation from a technical perspective is a topic worthy of study. In the heavy-haul railway train control system, the on-board ATP equipment plays an important role. It uses speed sensors, Beidou satellites and other technologies to fuse and process multi-source data to achieve accurate train positioning. According to the train parameters and the track circuit information, line data and temporary speed limit sent by the ground equipment, control curves are generated according to the target-distance mode to monitor the safe operation of the train. Therefore, the safety and reliability of the ATP equipment during operation is directly related to the safety and stability of the entire system. All information needs to be aggregated and processed by the ATP device to generate a vehicle control speed curve to monitor and supervise driving safety.
[0003] However, in the current on-board ATP implementation technology, the hardware uses the safety platform structure, HR hazard source analysis and other means to ensure the safety and reliability of ATP hardware. The software adopts the technical measures of safety software specifications in the design, development, testing, integration and other links of the software, and adopts the technical means of safety software coding specifications for software development to ensure the correctness and reliability of the software logic function. The final safety assessment is also to ensure the safety and reliability of the entire system for third-party verification and confirmation. These technical means are based on the technical capabilities and levels of personnel, and have certain limitations. They require more innovative research and development of monitoring software suitable for ATP equipment, resulting in poor monitoring accuracy of the entire heavy-duty railway system.

[0027] Embodiment 1
[0028] Figure 1 The following is a flow chart of a method for monitoring the onboard status of a heavy-load train provided in an embodiment of the present disclosure. Figure 1 As shown, a method for monitoring the onboard status of a heavy-load train comprises:
[0029] S1. Obtain a train control function set and a train control message set of a heavy-duty train control system, and construct a function message mapping table according to the train control function set and the train control message set.
[0030] In the disclosed embodiment, a heavy haul railway control system refers to a train operation control system specially designed for heavy haul railway transportation. The heavy haul railway control system can provide guarantees for ensuring the safety, efficiency and reliability of train operation.
[0031] Specifically, the heavy haul railway control system consists of central equipment, station equipment, trackside equipment, on-board equipment, network security system, on-track operation civil defense system, etc. The train control function set is the functional processing that the automatic train protection (ATP) in the heavy haul railway control system needs to have in the entire operation process. The train control message set is the collection of information that ATP interacts with various external devices by obtaining various information provided by other devices. The function message mapping table is a relationship table that associates the train control message with the ATP train control function to form a corresponding relationship.
[0032] Among them, the train control functions can include self-test function, function of outputting normal braking and emergency braking, train overspeed protection function, speed measurement and calculation function, train multi-source fusion positioning function, satellite data processing function, runaway protection function, regressive protection function, track circuit information receiving function, vehicle-ground wireless communication function, line data information receiving function, vehicle control curve calculation function, human-computer interaction function, automatic over-phase function, assisted driving function, non-stop switching with LKJ, intelligent sensing alarm and other train control functions.
[0033] In the embodiments of the present disclosure, refer to Figure 2 As shown, a function message mapping table is constructed according to the train control function set and the train control message set, including:
[0034] S21. Obtaining a working device corresponding to each train control function in a train control function set;
[0035] S22, collecting train control messages from working equipment;
[0036] S23. Establishing an association relationship between each train control function and the train control message according to the train control message;
[0037] S24. Generate a function message mapping table according to the association relationship.
[0038] In the disclosed embodiment, the working equipment is a device that interacts with the heavy-load train control system, including devices that directly interact with data and indirectly obtain data, such as transponder equipment, data management server equipment, track circuit and satellite communication equipment, and other devices that directly interact with messages, as well as devices for data monitoring by a third party.
[0039] Furthermore, different working devices will output different train control messages, and the train control messages are composed of different parameter data, as shown in Table 1, wherein the first row in Table 1 represents the working device, and the first column represents the train control message.
[0040] In the embodiment of the present disclosure, the train control information contained in each train control function can be determined through the train control message, and then the association relationship between the train control function and the train control message can be established. For example, the working equipment corresponding to the output of common braking and emergency braking functions includes positioning messages, line messages, temporary speed limit messages, etc. Therefore, a function message mapping table can be constructed according to the association relationship between each train control function and the train control message, as shown in Table 2.
[0041] S2. Collect direct messages and indirect messages of the heavy-load train control system, and map the mapping functions corresponding to the direct messages according to the function message mapping table.
[0042] In the disclosed embodiment, direct messages and indirect messages are messages received by the automatic train protection (ATP) at the current moment, including messages for direct data interaction and messages from third parties obtained indirectly, which can be collected through the network interface of ATP.
[0043] In an embodiment of the present disclosure, direct messages and indirect messages of a heavy-load train control system are collected, including: obtaining a direct network interface and an indirect network interface corresponding to the heavy-load train control system; and collecting direct messages and indirect messages of the heavy-load train control system according to the network data interface and the indirect network interface.
[0044] In the disclosed embodiment, the direct network interface and the indirect network interface are the network data interfaces of all interface devices corresponding to the ATP device. The network data interface can be used to obtain messages for direct interaction and indirect acquisition of the heavy-load train control system. For example, these messages may be direct messages from transponders, data management equipment, track circuits and satellites, as well as input indirect messages sent to the ATP by other ground equipment.
[0045] In the disclosed embodiment, the mapping function is the train control function corresponding to the direct message in the function message mapping table. Through the mapping function, it can be determined which train control functions in the heavy-loaded train send the messages. For example, the output of normal braking and emergency braking will send positioning messages, line data messages, temporary speed limit messages, etc. The train overspeed protection function will send line data messages, temporary speed limit messages, over-phase messages, etc. Each message is composed of different data parameters to monitor the heavy-loaded train more accurately.
[0046] In the disclosed embodiment, mapping the mapping function corresponding to the direct message according to the function message mapping table includes: searching the function set matching the direct message in the function message mapping table; and performing pattern screening on the matching function set to obtain the mapping function corresponding to the direct message.
[0047] In the disclosed embodiment, a direct message is searched in the function message mapping table to obtain a matching function set that matches the direct message, but the matched functions may come from multiple modes, wherein a mode is the operating state of a heavy-load train when it is put into operation. Once a mode is put into operation, it must be converted in different modes, as shown in Table 3. Therefore, the matching function set may include train control functions of multiple modes, but the direct information collected at the current moment should come from the current mode of the heavy-load train. The mode is screened by the current mode of the heavy-load train, and the train control functions of the current mode are screened from the matching function set to obtain the mapping function.
[0048] In the disclosed embodiment, by mapping the mapping functions corresponding to the direct messages through the function message mapping table, accurate message events can be generated through the parameters of the direct messages, which can improve the accuracy of subsequent vehicle status warnings.
[0049] S3. When the mapping function is a preset monitoring function, determine whether the overload train control system triggers a valid event based on the mapping function and the indirect message.
[0050] In the disclosed embodiment, the monitoring function is a monitorable function, which may include functions such as calculating a vehicle control curve and protecting against train overspeeding. When the mapping function is a monitorable function, a judgment is made on the triggering of an effective event.
[0051] In the disclosed embodiment, a valid event is a valid event that triggers the state transition of a heavy-loaded train, that is, when the mapping function and the indirect message cause a mode change, an output change, or a functional logic change of the automatic train protection (ATP), it indicates that the heavy-loaded train control system has triggered a valid event.
[0052] In the embodiments of the present disclosure, refer to Figure 3 As shown, the heavy load train control system is judged whether to trigger a valid event based on the mapping function and the indirect message, including:
[0053] S31, mapping the indirect mapping function corresponding to the indirect message;
[0054] S32, constructing direct events and indirect events according to the indirect mapping function and the mapping function;
[0055] S33. Using a preset judgment function, judging whether the overloaded train control system triggers a valid event according to direct events and indirect events.
[0056] In the embodiment of the present disclosure, the indirect mapping function is an indirect mapping function obtained by mapping according to the function message mapping table, and the train control function and the corresponding message are combined into one event. For example, the direct message includes Build direct events from mapping functions Among them, e represents the mapping function; indirect messages include Indirect events can be constructed based on indirect mapping functions
[0057]
[0058] In the embodiment of the present disclosure, the preset judgment function can be J=F(e,I), which means that the data parameters in the direct event must match the data parameters in I. If the parameters in the direct event are greater than the allowable values of the parameters in the input indirect event, the direct messages and indirect messages collected by the overloaded train control system correspond to invalid events. If the parameters in the direct event are not greater than the allowable values of the parameters in the input indirect event, it means that the overloaded train control system has triggered a valid event.
[0059] In detail, the judgment function can be a preset judgment logic, and according to the judgment function, it can be determined whether the events corresponding to the direct message and the indirect message trigger a valid event, and then the indirect message from the third party can be combined to perform vehicle status warning, thereby improving the accuracy of the vehicle status warning.
[0060] S4. When the mapping function is not the preset monitoring function, return to the above step S2. Collecting direct messages and indirect messages of the heavy-load train control system.
[0061] In the disclosed embodiment, when the mapping function is not the preset monitoring function, it means that the mapping function cannot cause a change in the state of the overloaded train control system, that is, the state cannot be monitored. Therefore, it is necessary to return to the above S2 and collect direct messages and indirect messages of the overloaded train control system, and then collect direct messages and indirect messages at the next time point.
[0062] Furthermore, the collection of direct messages and indirect messages at multiple time points can be performed through a data processing queue.
[0063] S5. When the overload train control system triggers a valid event, a migration state set of the overload train control system is constructed according to the direct message.
[0064] In the disclosed embodiment, the heavy-load train control system requires an external valid event to trigger the vehicle status warning, that is, when the heavy-load train control system triggers a valid event, the next step of the vehicle status warning is performed.
[0065] In the disclosed embodiment, the migration state set is the heavy-duty train control system moving from one state to another, so it is a mapping function: the input is a state and a trigger event, the input is a new state, and the migration state set is obtained.
[0066] In an embodiment of the present disclosure, a migration state set of an overloaded train control system is constructed based on a direct message, including: calculating the migration state of the overloaded train control system using a direct event corresponding to the direct message; adding the migration state to a preset state set of the overloaded train control system to obtain a migration state set of the overloaded train control system.
[0067] In the disclosed embodiment, the migration state is a stage in the early warning monitoring process of the heavy-load train control system. Each trigger event corresponds to a migration state, which can be defined according to the trigger event to obtain the migration state corresponding to each direct event, wherein the migration state includes the direct event and the corresponding migration state.
[0068] In detail, the preset state set is a state set of the historical event node in the heavy-load train control system, which is initially an empty set. The state is added according to the migration state to obtain the migration state set.
[0069] In the embodiment of the present disclosure, when the overloaded train control system does not trigger a valid event, the process returns to the above step S2, collecting direct messages and indirect messages of the overloaded train control system.
[0070] In the disclosed embodiment, when the heavy-loaded train control system does not trigger a valid event, it indicates that the heavy-loaded train control system has not triggered a valid event to perform a vehicle status warning. Therefore, it is necessary to return to the above-mentioned S2 and the step of collecting direct messages and indirect messages of the heavy-loaded train control system, and then collect direct messages and indirect messages at the next time point.
[0071] S6. Use the migration status set to issue an onboard status warning to the heavy-load train corresponding to the heavy-load train control system.
[0072] In the disclosed embodiment, the vehicle status warning is determined based on the signal safety principle and the fault safety principle to determine whether all states in the migration state set are in failure. If they are in failure, a corresponding vehicle status warning is issued.
[0073] In an embodiment of the present disclosure, a migration status set is used to perform an on-board status warning for a heavy-loaded train corresponding to a heavy-loaded train control system, including: determining a failure event corresponding to the heavy-loaded train control system according to the migration status set; identifying a failure level of the heavy-loaded train control system according to the failure event; and using the failure level to perform an on-board status warning for the heavy-loaded train corresponding to the heavy-loaded train control system.
[0074] In the embodiment of the present disclosure, a failure event refers to when the migration state in the migration state set is equal to the state at the previous moment and the migration state belongs to the preset warning state, it means that the migration state is a failure state, and the direct event of the migration state is a failure event.
[0075] In detail, the warning state can be determined based on the preset signal safety principle and the fail-safe principle. For example, the speed of ATP output exceeds the safety value, which is a defined warning state.
[0076] Furthermore, the failure level is identified according to the data parameters in the failure event, wherein the failure level of the heavy-load train control system can be identified according to the preset parameter level table, and if the failure level is the highest level, an early warning is issued. If it is not the highest level, it is tolerable, and if the accumulated secondary failure states exceed the threshold, an early warning is issued, so that the migration state in the state set can be iteratively warned.
[0077] In the disclosed embodiment, an on-board status warning is performed on the heavy-load train corresponding to the heavy-load train control system through the migration status set. According to the implementation status of the ATP equipment between the heavy-load train control systems and the indirect messages sent to the ATP by other ground equipment, the state machine action of the ATP equipment can be monitored in real time in the form of a third party, and an alarm can be issued in time when an abnormality is found, and manual confirmation and necessary intervention can be carried out in real time, thereby ensuring that the protection function of the ATP is safer and more reliable, and can effectively improve the accuracy of monitoring during the operation of heavy-load trains.
[0078] Embodiment 2
[0079] On the basis of the above embodiments, in order to more clearly understand the present disclosure, a second embodiment is used below to further explain the situation in which the first embodiment of the present disclosure needs to more quickly construct a function message mapping table according to the train control function set and the train control message set.
[0080] In the embodiment of the present disclosure, a function message mapping table is constructed according to a train control function set and a train control message set, including:
[0081] Obtain the mapping relationship between each train control function in the train control function set and each train control message in the train control message set;
[0082] Fill in the mapping relationship into the pre-built mapping table to obtain the function message mapping table.
[0083] In the disclosed embodiment, the mapping relationship is the association relationship between the train control message and the train control function, which can be pre-set according to the message generated by each function of the automatic train protection (ATP) equipment during operation.
[0084] Furthermore, the mapping table is a pre-set data structure for storing the mapping relationship between train control functions and train control messages. The mapping table can quickly store the mapping relationship between train control functions and train control messages, thereby improving the efficiency of constructing the function message mapping table.
