Specifically, as shown in fig. 2, in the urban rail transit broadcast, the multiple hierarchical control centers of the present application include: the broadcasting system comprises a road network center broadcast, a line control center broadcast and a station broadcast, wherein the road network center broadcast corresponds to a road network control center in the application, the line control center broadcast corresponds to a target line control center in the application, and the station broadcast corresponds to a target station control center in the application, wherein a preset broadcast table in the application can be a broadcast schedule table which is manufactured in advance by planning and broadcasting contents of one or more lines, one or more stations and one or more partitions, and the station broadcast system carries out planned broadcasting according to the broadcast schedule.
After a plurality of hierarchical control centers are determined, a service requirement corresponding to each hierarchical control center needs to be determined, and a plurality of preset playlists of the method are determined according to the service requirement, so that services can be broadcasted more efficiently, optionally, in the broadcasting method of the track traffic broadcast provided by the embodiment of the present application, determining the plurality of preset playlists includes: collecting playing task demands corresponding to a plurality of hierarchical control centers, wherein each hierarchical control center corresponds to at least one playing task demand; determining a playlist template corresponding to each play task requirement, wherein the playlist template at least comprises one of the following components: a scene prefabricating template, a historical broadcasting table template and a blank template, wherein the blank template is a template which does not contain any broadcasting task plan; and generating a preset playlist corresponding to each level control center according to the plurality of playlist templates to obtain a plurality of preset playlists.
For example, the playing task requirements corresponding to a plurality of hierarchical control centers are collected, subway operation staff can reasonably arrange the contents to be played according to the playing task requirements, and determine a playing table template corresponding to each playing task requirement, wherein the playing table template can be divided into a scene prefabrication template, a history playing table template and a blank template. For example, a scene pre-template may be represented as: different service templates are made in advance according to different time or different scenes such as working days, holidays, morning and evening peaks and the like, and the historical broadcasting template can be expressed as: the playlist executed in the system before can be stored as a template, when a dispatcher needs to create a new playlist, a proper template can be selected as a new playlist to be edited according to the situation, and the blank template can be expressed as: the method does not include any template of the play plan task, and each level can make a pre-made playlist (corresponding to the pre-made playlist in the present application, the same applies below) according to different playlist templates and the like, wherein the pre-made playlist can be a task list including effective dates, and the task list can be used as a playlist. One playlist can contain one or more tasks, each task item comprises broadcast date, broadcast time, category, area, material information and the like, the broadcast of the existing live broadcast mode can be updated and supplemented by determining a plurality of preset playlists, the broadcast content, the broadcast range and the broadcast time of the broadcast are prefabricated in advance, a station broadcast system only needs to execute according to a plan in the playlists, and the broadcast efficiency of the tasks is further improved.
And S102, determining a first issuing playlist to be issued to a target line center by the road network control center according to the first preset playlist.
Specifically, as shown in fig. 2, after the higher level broadcast table is verified and confirmed, the higher level broadcast table can be automatically issued to the lower level broadcast system, and it should be noted that if there is no specific broadcast task, the higher level broadcast system automatically issues a blank broadcast table to the lower level broadcast system.
Optionally, in the broadcast method of the track traffic broadcast provided in the embodiment of the present application, determining, according to a first preset playlist, a first broadcast schedule to be issued by a road network control center to a target route center includes: judging whether the first preset playlist needs to be adjusted or not; if the first preset playlist does not need to be adjusted, taking the first preset playlist as a first downlink playlist; and if the first preset playlist needs to be adjusted, responding to an adjustment instruction of the first preset playlist to obtain the adjusted first preset playlist, and taking the adjusted first preset playlist as a first downlink playlist.
For example, at time T1, the road network layer broadcasting system automatically extracts the next day task from the system pre-prepared playlist, and before a time point T2 every day (T1 is less than T2), the road network layer broadcasting system should automatically generate the current-level playlist to be distributed (i.e., the first broadcast list) according to the system pre-prepared playlist (i.e., the first pre-set playlist), and if the to-be-distributed playlist is manually adjusted, the adjusted first pre-set playlist should be checked and confirmed to be used as the first broadcast list before distribution. By checking the to-be-issued playlist, the task list in the to-be-issued playlist is more accurate.
Optionally, in the broadcast method of the track traffic broadcast provided in the embodiment of the present application, after determining, according to a first preset playlist, a first delivered playlist to be delivered by a road network control center to a target route center, the method further includes: setting a first moment; triggering an issued instruction in a road network control center according to a first moment; and issuing the first issuing playing table to a target line control center according to the issuing instruction.
For example, the network-level broadcast table should automatically issue the first issued broadcast table to the line center layer broadcast system at the time point T2 (i.e., the first time in this application). If no specific play task exists, a blank play list is issued, and the application automatically triggers through time, so that the real-time performance of broadcast play is guaranteed.
Step S103, processing the first downlink playlist and the second preset playlist received by the target line control center to obtain a fourth preset playlist.
Specifically, the line center layer broadcasting system automatically extracts the next-day task list (i.e., the second preset playlist in the present application) from the system preset playlist, and processes the first broadcast list and the second preset playlist received by the target line control center.
Optionally, in the broadcast method of the track traffic broadcast provided in the embodiment of the present application, the processing the first broadcast schedule and the second preset broadcast schedule received by the target line control center, and obtaining a fourth preset broadcast schedule includes: merging the first issuing playlist received by the target line control center with a second preset playlist to obtain a merged first issuing playlist; judging whether a time overlapping service exists in the merged first next broadcast list or not, wherein the time overlapping service is a service broadcasted at a target line control center at the same time; if the time overlapping service does not exist in the merged first sending play list, taking the merged first sending play list as a fourth preset play list; and if the time overlapping service exists in the merged first downlink playlist, processing the merged first downlink playlist to obtain a fourth preset playlist.
Specifically, at time T3 (T3 is greater than T2), the line center layer broadcasting system should automatically generate a local broadcast list to be distributed (a second preset broadcast list) according to the local broadcast list, combine the local broadcast list with the received network level broadcast list (a first broadcast list to be distributed), and form an enterprise/line level broadcast list to be distributed (a fourth preset broadcast list) after task priority conflict processing, specifically, the task priority conflict is also a time-overlapping service, for example, a broadcast task in the broadcast and broadcast broadcasting process is subjected to broadcast and broadcast priority conflict judgment by taking a station broadcast zone as a unit, the broadcast task includes 1 or more broadcast zones, and as long as the station broadcast zones have the same time conflict, all broadcast tasks (own station) with low broadcast and broadcast priority are interrupted, and the time of the broadcast tasks is rearranged, so that when subsequent broadcast lists do not have priority conflicts, the broadcast efficiency is further improved.
Optionally, in the broadcast method of the track traffic broadcast provided in the embodiment of the present application, if there is a time overlap service in the merged first broadcast table, processing the merged first broadcast table to obtain a fourth preset broadcast table includes: determining a time overlapping service; and readjusting the playing time of the time-overlapped service in the merged first next playing list according to the service priority of the time-overlapped service to obtain a fourth preset playing list, wherein the playing time corresponding to the time-overlapped service with high service priority is earlier than the playing time corresponding to the time-overlapped service with low service priority.
For example, the first broadcast table includes a task list a issued at a preset time for a plurality of stations, and the target station control center also includes a task list B issued at a preset time in the second broadcast table, so that the task list a is used
And taking the task corresponding to the task list B as the time overlapping service in the application, if the importance degree of the task A is higher than that of the task A
B task, namely, the priority of the A task is higher than that of the B task, and the B task is readjusted in the merged first issuing playlist
The playing time of the task B is set to be later than that of the task A, so that the fact that the priority conflict does not exist in the playing list in the subsequent execution process is guaranteed, and the broadcasting efficiency of the tasks is further improved.
Step S104, in the target station control center, determining a target playlist according to a fourth preset playlist and a third preset playlist, wherein the target playlist at least comprises: a play plan for a plurality of tasks.
Optionally, if the fourth preset playlist obtained by the target line control center does not need to be adjusted, the fourth preset playlist is directly issued to the target station control center at the time T4 (T4 is greater than T3).
Optionally, in the broadcast method of the track traffic broadcast provided in the embodiment of the present application, in the target station control center, determining the target playlist according to the fourth preset playlist and the third preset playlist includes: merging the fourth preset playlist and the third preset playlist to obtain a merged fourth preset playlist, and judging whether a time overlapping service exists in the merged fourth preset playlist, wherein the time overlapping service is a service broadcasted at a target station control center at the same time, if the time overlapping service does not exist in the merged fourth preset playlist, the merged fourth preset playlist is used as a fifth preset playlist, and if the time overlapping service exists in the merged fourth preset playlist, the merged fourth preset playlist is processed to obtain the fifth preset playlist; and judging whether the fifth preset playlist needs to be adjusted, if so, responding to an adjustment instruction of the fifth preset playlist to obtain the adjusted fifth preset playlist, taking the adjusted fifth preset playlist as a target playlist, and if not, taking the fifth preset playlist as the target playlist.
For example, at time T5 (T5 is greater than T4 described above), the station-level broadcasting system automatically extracts the next-day task from the system-ready broadcast table (corresponding to the third pre-determined broadcast table in the present application), and merges the next-day task with the received fourth pre-determined broadcast table, and after the task priority conflict processing, forms the station-ready-to-execute broadcast table. The task priority conflict processing in this place is the same as the operation principle in step S103, and is not described in detail here, and optionally, if there is a manual adjustment on the playlist to be executed (the fifth preset playlist), the playlist needs to be checked and confirmed to be adjusted to the target playlist in this application, so that the task list in the playlist to be issued is more accurate.
And step S105, broadcasting a plurality of tasks in a target station control center according to the target play list.
For example, the target station control center automatically generates the current-day execution broadcast table at a time point T6 (T6 is greater than T45) according to the target broadcast table, and the station layer broadcast system automatically feeds back the broadcast table to the road network layer broadcast system and the line center layer broadcast system, after the operation starts, the station layer broadcast system formally executes the broadcast table, and after the operation ends, the station layer broadcast system should immediately automatically feed back the final execution result of the current-day broadcast table to the road network layer broadcast system and the line center layer broadcast system.
It should be noted that, in the present application, the content scheduled to be broadcast by one or more lines and one or more partitions at one or more stations may be made into a broadcast schedule (also referred to as a broadcast schedule) in advance.
Optionally, in the process of executing the broadcasting table by the station system: the road network center can only cancel tasks which are created by the current level and are not executed in the broadcast list; the line control center can only cancel tasks which are created by the current stage and are not executed in the broadcast list; the station control center can cancel tasks which are created at the current level and are not executed, and in an emergency, the station can cancel all the broadcasting tasks on the current day by one key.
Optionally, the playlist state monitoring and feedback process: the broadcasting system operating terminal should be able to display the conflict situation of each task when the broadcasting system generates the current-level broadcasting list. In the process of gradually issuing the superior broadcasting list, if the superior broadcasting list conflicts with tasks of all levels of broadcasting lists, after the station generates the current-day execution broadcasting list, the superior broadcasting system synchronously receives all levels of task conflict conditions totally fed back by the station broadcasting system; in the table broadcasting execution process, after the specific task is executed, the station system should feed back the task execution state to the road network layer broadcasting system and the line center layer broadcasting system in time.
