Technical Field

Background
In the operation process of an Automatic Train monitoring system (Automatic Train Supervision, hereinafter referred to as "ATS") of urban rail transit, manual operations such as power-on in the morning, Train awakening dormancy, Train delivery and the like exist; normal conditions in the operation process, such as operation of a rolling way vehicle, full-automatic driving and the like, can also exist; there are also various emergencies such as station fires, train fires, etc. The traditional method develops a linkage interface by signal system specialty and comprehensive monitoring specialty for linkage related to a signal system and other specialties, and issues commands to process emergencies by a dispatcher for problems only related to the signal system or a general dispatcher according to the content of an emergency treatment plan manual.
The linkage scheme is triggered by predefined time or event to execute a group of control commands related to a plurality of subsystems, thereby completing the cooperative control of the corresponding subsystems. For example, when the morning startup time is reached, the linkage function sequentially triggers the morning startup modes of the environmental and equipment monitoring system, the tunnel ventilation system, the power lighting system, the broadcasting system and other subsystems; when the automatic fire alarm system triggers an alarm, the linkage function firstly starts the video monitoring system for the dispatcher to confirm the scene condition related to the alarm, and then the dispatcher performs semi-automatic linkage to trigger the corresponding operation of each related subsystem.
However, as the urban rail transit field enters a full-Automatic driving era (hereinafter referred to as "FAO"), the supporting strength of the traditional linkage scheme for the FAO is insufficient, for example, a newly added dormancy wakeup plan in a FAO scene, and a condition of the plan needs to be determined in the linkage scheme; the traditional linkage scheme needs support of a comprehensive monitoring manufacturer, but in newly added FAO operation scenes, such as linkage of dormancy, awakening, car washing and the like, the whole linkage link is completely in the signal specialty, and relevant command issuing in the field of comprehensive monitoring is not involved; and the interior of the traditional signal system is mainly provided with a special data structure and a special protocol, and a corresponding linkage scheme can not be flexibly set according to an actual scene.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a train linkage control method according to a first embodiment of the present invention, and as shown in fig. 1, the train linkage control method according to the first embodiment of the present invention includes the following steps:
In this step, it should be noted that, in the running process of the train, linkage operation needs to be performed on corresponding equipment according to different scenes. For example, when the start time of a train arrives in the morning, the traditional method can sequentially link and trigger an environment and equipment monitoring system, a tunnel ventilation system, a power lighting system and a broadcasting system. However, when the application scenes in which train broadcasting is not required (i.e. the broadcasting system is not required to be triggered), since the linkage trigger sequence started in the morning is written into the software codes in the conventional method, if the broadcasting system is skipped, a software developer needs to modify the corresponding program codes, which is inefficient, and if each scene is programmed with the corresponding program codes, the code redundancy in the software is caused.
Therefore, in the embodiment, the linkage trigger nodes are matched according to the application scenes, so that the corresponding linkage trigger models can be flexibly matched in different application scenes, compared with the conventional method that corresponding program codes need to be written for each application scene and software developers need to complete corresponding work, the method provided by the embodiment selects the linkage trigger nodes according to the application scenes, and then establishes the linkage trigger models according to the linkage trigger nodes without modifying or writing the corresponding program codes by the software developers, so that the user can complete operation according to actual requirements, the working efficiency is improved, and program redundancy caused by writing a large number of program codes in the conventional method is avoided.
Specifically, according to the application scenario to be subjected to train linkage, each linkage trigger node and each linkage trigger model matched with the application scenario are determined. The linkage triggering model is a logic expression established by taking the logic value of each linkage triggering node as an independent variable and is used for expressing the customization requirements of users. Fig. 2 is a schematic diagram of a train linkage control processing flow according to a first embodiment of the present invention, and as shown in fig. 2, in this embodiment, linkage trigger nodes such as presentation information, train information, plan information, and the like are freely combined, so that a user can describe a specific scene through a relational expression and a logical expression. Through the combination of various types of state information, such as train state information, current occupancy position information and plan information, the logic expression is as follows: and the train state information (&) current occupancy position information (&) plan information for expressing a trigger condition of the current train at a designated position and at a designated time. By analogy, various information in the signal system can establish corresponding logic expressions by taking the logic values of the linkage trigger nodes as independent variables through the linkage state model, so that the customization requirements of the FAO under various operation scenes are met.
And step 120, acquiring the logic values corresponding to the linkage trigger nodes stored in the ATS cache, inputting the logic values corresponding to the linkage trigger nodes into a linkage trigger model, and judging whether linkage control is performed according to a logic calculation result.
In this step, the logical values corresponding to the respective linkage trigger nodes are acquired from the ATS cache, and the logical values corresponding to the respective linkage trigger nodes are input to the linkage trigger model, and logical operation is performed to determine whether a linkage trigger condition is satisfied, thereby performing train control. Correspondingly, if the logic calculation result meets the linkage control triggering condition, linkage control is carried out.
For example, for a train wake-up application scenario, the linkage trigger nodes are train state information, train position information, train occupancy information, and a wake-up plan, and the train triggers train wake-up when the following conditions are simultaneously met: the train is in a sleep permission awakening state (the logic value is 1); secondly, the train has a designated track (the logic value is 1); the current track is occupied by the train (the logic value is 1); and fourthly, designating the awakening time (the logic value is 1). And when the logic values of the train state information, the train position information, the train occupation information and the awakening plan in the ATS cache are all 1, triggering the awakening command, otherwise, not starting the awakening command.
Therefore, in the embodiment, each linkage trigger node is stored in a logic value form, so that not only is the data storage structure simplified and unified and the flattening of data realized, but also the stored logic values of the linkage trigger nodes can be applied to different application scenes, and whether the linkage trigger conditions are met or not can be quickly and accurately judged through simple logic operation, thereby carrying out linkage control. Meanwhile, in the embodiment, the logic values corresponding to the linkage trigger nodes are stored in the ATS, and when different scenes are faced, the linkage trigger model can be established by using the logic values of the linkage trigger nodes stored in the ATS.
According to the train linkage control method provided by the embodiment of the invention, each linkage trigger node matched with an application scene and a linkage trigger model are determined according to the application scene to be subjected to train linkage, the linkage trigger model is established according to the linkage trigger nodes matched with the scene, so that the corresponding linkage trigger model is flexibly matched according to different application scenes, and the logic value of each linkage trigger node is stored in the ATS cache, so that the data storage structure is simplified, and each linkage trigger node is stored in the form of the logic value, so that the logic operation can be carried out among different linkage trigger nodes, the logic value of each linkage trigger node is input into the linkage trigger model, and whether linkage control is carried out or not can be judged according to the logic calculation result. Therefore, the embodiment of the invention realizes that the corresponding linkage trigger models can be flexibly matched in different application scenes by matching the linkage trigger nodes according to the application scenes, and each linkage trigger node is stored in a logic value form, so that not only is the data storage structure simplified and unified, but also the stored logic values of the linkage trigger nodes can be applied to different application scenes, and whether the linkage trigger conditions are met or not is quickly and accurately judged through logic operation, thereby carrying out linkage control.
Based on the content of the above embodiment, as an optional embodiment, the logical value corresponding to each linkage trigger node is obtained through a message parsing protocol, and a mapping relationship between the linkage trigger node and the logical value of the linkage trigger node is established in the message parsing protocol, so as to obtain the linkage trigger node and the logical value of the linkage trigger node carried in the communication message received by the ATS.
In this step, since the ATS obtains information of each linkage trigger node by parsing the communication packet, specific state information corresponding to each linkage trigger node is obtained after parsing the communication packet in the conventional method, and logical operation cannot be performed between each specific state information. For example, in the conventional method, the information obtained after the communication packet is analyzed is as follows: train state information-in sleep enable awake state, train position information-exists on the designated track. However, the two specific information "in the sleep permission wake-up state" and "existing in the designated track" cannot be logically operated at all, so that in the present embodiment, a mapping relationship between the logical values of the linkage trigger node and the linkage trigger node is established in the packet resolution protocol, that is, a mapping relationship between the "in the sleep permission wake-up state" and the "logical value 1" and a mapping relationship between the "existing in the designated track" and the "logical value 1" are established, and thus the "logical value 1" corresponding to the two states can be logically operated.
Therefore, in the embodiment, by establishing the mapping relationship between the linkage trigger node and the logical value of the linkage trigger node in the message parsing protocol, each linkage trigger node and the corresponding logical value thereof can be directly obtained from the parsed message protocol, so that the logical value of the corresponding linkage trigger node can be directly obtained from the ATS cache during subsequent logical operation, and whether linkage control is performed or not can be quickly judged according to the logical calculation result.
According to the train linkage control method provided by the embodiment of the invention, the mapping relation between the linkage trigger node and the logical value of the linkage trigger node is established in the message analysis protocol, and the linkage trigger node and the logical value of the linkage trigger node carried in the communication message received by the ATS are obtained according to the message analysis protocol, so that the logical value of the corresponding linkage trigger node is directly obtained from the ATS cache during subsequent logical operation, and whether linkage control is carried out or not is quickly judged according to the logical calculation result.
Based on the content of the foregoing embodiment, as an optional embodiment, if the linkage trigger node is a basic node, a mapping relationship between the linkage trigger node and a logical value of the linkage trigger node is established in the message parsing protocol, which includes:
establishing a mapping relation between a basic node and a logical value of the basic node in a message analysis protocol; the basic nodes comprise a train driving mode, a train speed, a train sleeping and awakening state, a train working mode and a train working state.
In this step, since the linkage trigger node includes various information such as presentation information, train information, plan information, and the like, the present embodiment classifies it into a basic node, a logical node, and a relational node. The basic nodes comprise a train driving mode, a train speed, a train sleeping and awakening state, a train working mode and a train working state. And if the linkage trigger node is a basic node, establishing a mapping relation between the basic node and the logic value of the basic node in the message analysis protocol. For example: for the train sleeping and awakening state, the existing logic is expressed as 2 types of '1' -in the train sleeping and awakening state; 0-not in the train sleeping and awakening state ", so that the mapping relation between the 'in train sleeping and awakening state' and the 'logic value 1' and the 'not in train sleeping and awakening state' and the 'logic value 0' can be established.
According to the train linkage control method provided by the embodiment of the invention, the linkage trigger node and the logical value of the linkage trigger node can be quickly obtained by establishing the mapping relation between the logical values of the basic node and the basic node in the message analysis protocol, so that the logical value of the corresponding linkage trigger node can be directly obtained from an ATS cache during subsequent logical operation, and whether linkage control is carried out or not can be quickly judged according to the logical calculation result.
Based on the content of the foregoing embodiment, as an optional embodiment, if the linkage trigger node is a logical node, a mapping relationship between the linkage trigger node and a logical value of the linkage trigger node is established in the message parsing protocol, which includes:
determining a logic expression of the logic node by taking a basic node logic value contained in the logic node as a free measure, and establishing a mapping relation between the logic expression of the logic node and the logic value of the logic node in a message analysis protocol; wherein, the logic node is obtained by at least 1 basic node logic operation.
In this step, since the logical node cannot be obtained by directly mapping the basic node stored in the ATS, and only at least 1 basic node needs to perform logical operation, such as train location information, the present embodiment determines the logical expression of the logical node by using the logical value of the basic node included in the logical node as a convenience measure, and establishes the mapping relationship between the logical expression of the logical node and the logical value of the logical node in the message parsing protocol, thereby obtaining the mapping relationship between the logical node.
According to the train linkage control method provided by the embodiment of the invention, the linkage trigger node and the logical value of the linkage trigger node can be quickly obtained by establishing the mapping relation of the logical node in the message analysis protocol, so that the logical value of the corresponding linkage trigger node can be directly obtained from the ATS cache during subsequent logical operation, and whether linkage control is carried out or not can be quickly judged according to the logical calculation result.
Based on the content of the foregoing embodiment, as an optional embodiment, if the linkage trigger node is a relationship node, a mapping relationship between the linkage trigger node and a logical value of the linkage trigger node is established in the message parsing protocol, which includes:
determining a logical expression of the relational node by taking the logical value of the value interval of the basic node as an independent variable, and establishing a mapping relation between the logical expression of the relational node and the logical value of the relational node in a message analysis protocol; the relation nodes are obtained through logical operation of the value intervals of the basic nodes.
In this step, because the relationship node needs to perform logical operation according to the value interval of the base node and cannot be directly obtained by the direct mapping of the base node stored in the ATS, the present embodiment determines the logical expression of the relationship node by using the logical value of the value interval of the base node as an argument, and establishes the mapping relationship between the logical expression of the relationship node and the logical value of the relationship node in the message parsing protocol. For example, for wake-up time, the value interval is 7 a.m.: 00-9: 00, the wake-up time requirement is met only in the time period within the value interval, otherwise the wake-up time requirement cannot be met outside the value interval.
According to the train linkage control method provided by the embodiment of the invention, the linkage trigger node and the logical value of the linkage trigger node can be quickly obtained by establishing the mapping relation of the relation node in the message analysis protocol, so that the logical value of the corresponding linkage trigger node can be directly obtained from the ATS cache during subsequent logical operation, and whether linkage control is carried out or not can be quickly judged according to the logical calculation result.
Based on the content of the above embodiment, as an optional embodiment, the linkage trigger model is a binary tree structure.
In the step, the linkage trigger model adopts a binary tree structure, so that the linkage trigger model can be established according to different scenes, and the linkage trigger model with the binary tree structure is convenient to sort and search.
