Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant disclosure and are not limiting of the disclosure. It should be noted that, for the convenience of description, only the portions relevant to the application are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is an architecture diagram of an implementation environment of a train tracking display according to an embodiment of the present application. As shown in fig. 1, the implementation environment architecture includes: a terminal 101 and an automatic train monitoring system 102.
The terminal 101 may be used to install a development platform, develop a program for Train tracking display through the development platform, and the program may be applied to an Automatic Train monitoring System 102 (hereinafter, referred to as "Automatic Train Supervision System"), control data interaction between the terminal 101 and the ATS102 through the program, for example, when track information changes, obtain changed track information from the ATS102, and obtain running information of a Train from the ATS102 in real time. Further, through the development platform, a train plug-in can be developed, which is used for acquiring required data from each storage position and sending the data to the display model so as to display the data through the display model.
The display model is also provided in the terminal 101, and is used to display various data that needs to be displayed in train tracking. For example, when a real-time tracking display of a train is performed, a station diagram (mainly displaying a track and a train number window template of the tracked train) is displayed through a display model; for example, before train tracking is performed, a user may draw a station yard map through the display model, for example, by dragging a train number window template, a template of a train track, and the like into the display model, so as to draw the station yard map. The yard graph includes all track information related to the tracked train, for example, the yard graph includes train number window templates, train tracks, semaphores, platform templates, and the like.
The terminal 101 is further provided with a platform database corresponding to the development platform, and configured to store static data and real-time data acquired from the ATS102, where the static data includes track information and data of a train number window template, and the real-time data includes train operation information.
In addition, the terminal 101 stores station map data (the station map data may be a DRP format file or other format file) which is displayed as a station map in the display model when read. Here, the yard graph data is stored in advance, and when a certain train needs to be tracked and displayed in real time, the train plug-in directly acquires the yard graph data and displays the data through the display model.
In addition, it should be noted that the track information and the train number window template are not absolute static data, but are changed relatively less frequently with respect to the train operation information. For example, a track is newly added, and the newly added track information also needs to be added to the platform database.
The type of the terminal 101 includes, but is not limited to, a smart phone, a tablet computer, a television, a notebook computer, a desktop computer, and the like, which is not particularly limited in this embodiment.
The ATS102 is configured to receive train operation information sent by a Vehicle-mounted Controller (VOBC), for example, a logical section identifier of a track logical section where a train is currently located, a train identifier, a train operation direction, a train door state of the train, and send the received train operation information to the terminal 101. The ATS102 is further configured to receive track information, such as coordinate positions of a traffic signal, a switch, and a track, sent by a Computer Interlock (CI), and send the received track information to the terminal 101.
In addition, the ATS102 is further configured with a system database corresponding to the ATS, for storing the corresponding relationship between the track logical segment identifier and the train number window template identifier, so as to be timely obtained when needed.
The terminal 101 establishes a communication connection with the ATS102 through a wired or wireless network.
Fig. 2 is a flowchart illustrating a train tracking display method according to an embodiment of the present application. The method shown in fig. 2 may be performed by the terminal 101 in fig. 1, and further may be performed by a train plugin, as shown in fig. 2, the method includes the following steps:
The tracked train may be a train or a plurality of trains. The present embodiment is described by taking a train as an example, and the other cases are similar to this.
The running information of the train further comprises train identification, running direction, door state, jump stop state, activation end state, alarm state, running mode and the like of the train.
Wherein, the track logical zone is a part of the composition track, i.e. one track comprises a plurality of track logical zones. Each track logical section corresponds to a logical section identifier, and the logical section identifier is used for uniquely identifying a section of the track logical section.
Further, a track logical section corresponds to at least one train number window template of a tracked train, because when a track runs only one train at any time, one track logical section corresponds to one tracked train, and when a track logical section runs different trains at different times, in this case, one track logical section corresponds to multiple trains.
The operation information of the tracked train is obtained through a VOBC (video object controller) loaded in the train, after the VOBC obtains the operation information of the tracked train, the operation information is sent to an ATS (automatic train control), and the terminal obtains the operation information from the ATS.
Optionally, the terminal may store the acquired operation information in the platform database so as to acquire the operation information in time.
The display model may display the station yard graph as required, for example, a track where the tracked train is located, a plurality of track logical zones included in the track, a logical zone identifier of each track logical zone, and a train number window template of the tracked train corresponding to each track logical zone are displayed. Thus, after the train number window template corresponding to the logical section identifier is determined in the display model, the determined train number window template can be displayed through the display model.
The train number window template is used for representing a tracked train when the train tracking display is carried out, and comprises a plurality of objects, and each object corresponds to one piece of operation information of the tracked train. The vehicle number window template shown in fig. 3 includes a first triangle 1, a second triangle 2, a third triangle 3, a first rectangle 4, a second rectangle 5, the letters "MM CCCC", the letters H, S, D, E, and the like. The first triangle 1 represents that a train runs rightwards, the second triangle 2 represents that the train runs leftwards, the third triangle 3 represents that a plurality of trains are overlapped (the plurality of trains run in the same track logic section), the first rectangle 4 represents that a right side activation end is activated, the second rectangle 5 represents that a left side activation end is activated, a letter MM CCCC is a train identification, a letter H represents a car-buckled state, a letter S represents a jump-stop state, a letter D represents that a car door is opened, and a letter E represents an emergency stop state.
Alternatively, referring to fig. 4, the train number window template may be created by:
Illustratively, the vehicle order window template is shown in fig. 3, wherein the first triangle 1, the second triangle 2, the third triangle 3, the first rectangle 4, the second rectangle 5, the letter "MM CCCC", and the letter H, S, D, E are all one basic primitive of the vehicle order window template.
The attributes are specific to the vehicle number window template and comprise colors, display states, flashing states, running states and the like.
Illustratively, taking the train number window template shown in fig. 3 as an example, for the basic primitive of the first triangle 1, the attributes selected for the basic primitive include color, display status and operation status, that is, the formula includes color, display status and operation status, and the trigger condition configured for the formula is that when the tracked train runs to the right, the first triangle 1 is displayed as green. Thus, when the running information of the tracked train includes the running information of "running right", the first triangle 1 in the train number window template is in a display state and is displayed in green.
As can be seen from the above process of establishing the train number window template, when one train number window template is established, it is equivalent to establishing a corresponding relationship among each basic primitive (i.e., object), recipe, and trigger condition (one kind of operation information) included in the train number window template, and recording the corresponding relationship as a first corresponding relationship. Thus, when the operation information of the tracked train is acquired, the corresponding basic primitive and the formula of the basic primitive can be determined according to the acquired operation information so as to trigger the formula of the corresponding basic primitive (or object).
Alternatively, step 202 may be implemented by:
firstly, establishing a corresponding relation between a logic section identifier and a train number window template identifier in advance, and recording the corresponding relation as a second corresponding relation;
secondly, searching a logic section identifier which is the same as the obtained logic section identifier of the tracked train in a second corresponding relation;
thirdly, acquiring a train number window template identifier corresponding to the same logic section identifier;
and fourthly, determining the train number window template corresponding to the train number window template identification obtained in the third step in the display model, wherein the train number window template determined in the display model is the train number window template required to be determined in the step 202.
Optionally, the correspondence between the logical segment identifier and the train number window template identifier may be stored by the following method:
step one, setting a logical section identifier for each track logical section, and setting a train number window template identifier for each train number window template;
in a second step, for each track, the following operations are performed: drawing a track logic section, a logic section identifier, a train number window template and a train number window template identifier which correspond to the display model on the display model so as to establish a corresponding relation between the two;
and thirdly, storing the corresponding relation between the logic section identification and the train number window template identification into a system database.
In addition, it should be noted that, when implementing train tracking display, only the correspondence between the logical segment identifier and the train number window template identifier is needed, so that when storing the correspondence, only the correspondence between the logical segment identifier and the train number window template identifier needs to be stored.
Optionally, displaying the train number window template corresponding to the logical segment identifier may be implemented by the following method:
firstly, determining an object corresponding to the running information of the tracked train;
and secondly, displaying the determined object in the train number window template corresponding to the logical section identifier so as to display the train number window template.
Optionally, when the train number window template is the train number window template shown in fig. 3, the train number window template corresponding to the logical segment identifier may also be displayed by the following method:
the method comprises the steps of firstly, determining a trigger condition included in operation information of a tracked train;
secondly, acquiring an object and a formula of the train number window template corresponding to the determined trigger condition;
and thirdly, executing the acquired formula on the acquired object to display the train number window.
The running information comprises at least one triggering condition, so that when the running information of the train is acquired, the corresponding triggering condition can be obtained; and because the corresponding relation among the triggering condition, the object and the formula is stored in the first corresponding relation, the object and the formula corresponding to the triggering condition can be searched from the first corresponding relation, so that the corresponding formula can be executed.
Illustratively, the operation information of the tracked train comprises a right operation and a right activation end opening, and then the corresponding objects are a first triangle 1 and a first rectangle 4; when the vehicle number window template is displayed, the displayed object comprises a first triangle 1 and a first rectangle 4, namely, the display of the vehicle number window template is realized. Further, when the first triangle 1 and the first rectangle 4 are displayed, the formulas of the first triangle 1 and the first rectangle 4 need to be acquired, and according to the formula display, if the formula of the acquired first triangle 1 is display and green, and the formula of the acquired first rectangle 4 is display and blue, the corresponding formula is executed, that is, the first triangle is displayed as green, and the first rectangle is displayed as blue, that is, the display of the train number window is realized.
In addition, it should be noted that, after initialization, each train number window template is in a hidden state, only when a tracked train runs to a certain track logical zone, the corresponding train number window template is displayed, and when the tracked train runs away from the track logical zone, the displayed train number window template is hidden, so that a worker can monitor the position of the tracked train.
In summary, in the train tracking display method provided in the embodiment of the present application, each track logical zone corresponds to one train number window template, and when a tracked train runs to the track logical zone, the train number window template corresponding to the track logical zone is displayed, and when the tracked train runs away from the track logical zone, the train number window template is hidden; therefore, the train number window template is not required to be drawn or erased after the position information of the tracked train is acquired, the problems of display lag and blockage in the prior art are solved, and the effects of improving display real-time performance and image fluency are achieved.
