Description
Technical Field
The invention relates to the technical field, in particular to a subway broadcasting system timing playing method based on multi-instruction multi-cycle.
Background
The current subway broadcasting system mainly has the functions of playing a single instruction and playing the instruction circularly for multiple times, and the function of playing the instruction at fixed time is not realized. The single command needs to be played manually, that is, when voice information needs to be broadcast at a certain moment, an operator must manually click a button for issuing the command, and then the command is transmitted to the background and then transmitted to the hardware equipment to play voice. Such a method is rather rigid and time and labor consuming. The function of instructing to play the given instructions circularly in a given time period is to set the given instructions to play the given instructions circularly in a given time period, and the instructions are played repeatedly just like a repeater, because some instructions only need to be played once, and some instructions need to be played for multiple times. Meanwhile, the function of instructing to circularly play for multiple times must play the instructions according to the order given by the instructions, and when the subway train comes, the instructions may be played instead of the required instructions but other unrelated instructions. Some commands need to be played by stepping on a time point, and the delay can be only a few seconds, which cannot be solved by the existing single-command playing function and command loop playing function. The subway has a plurality of subsystems which need to be cooperated, namely when other subsystems need to be opened, the function of circularly playing the instructions of the broadcasting system for a plurality of times can be automatically cancelled, and the given instructions cannot be played at the given time. The TTS (Text to Speech) playing function of the existing broadcasting system on the subway can only manually click and play a single piece of content input by a user, and cannot play the content input by the user at a given time, which is also a problem to be solved.

Detailed Description
Referring to fig. 1, the subway broadcasting system timing playing method based on multiple instructions and multiple cycles provided by the invention comprises the following steps.
And S1, acquiring and storing a to-be-played instruction, wherein the to-be-played instruction comprises playing time, playing times and playing contents.
In this step, the instruction to be played is manually input, an instruction task area for storing voice broadcast and TTS (texttostech, from text to voice) broadcast is provided in this step, and the instruction to be played is stored in the corresponding instruction task area according to the type of the instruction.
In the embodiment, the command to be played is stored in the form of 16-system ASCII code, so as to facilitate data reading and reshaping, and reduce the difficulty of analysis.
In specific implementation, the instructions to be played are all stored in the data structure, the number of the instructions stored in the data structure is fixed, and the size of the data structure can be determined according to actual needs.
And S2, analyzing the command to be played and obtaining the next playing command according to the playing time. Specifically, in this step, the command to be played, which is stored in the form of a character string, needs to be analyzed to obtain the playing time, the playing frequency, and the playing content.
And S3, when the playing time of the next playing instruction is reached, circularly playing the playing content according to the playing times.
Specifically, when the playing time of the next playing instruction is reached, firstly, whether the loudspeaker is in an idle state is judged, and if yes, the playing content is played circularly according to the playing times; and if not, circularly playing the playing content according to the playing times when the loudspeaker is idle.
The specific method for playing the playing content cyclically according to the playing times in step S3 is as follows: playing the playing content, and counting the actual playing cycle times; and comparing the playing cycle times with the playing cycle times, and continuing the cycle playing or ending the cycle playing according to the comparison result.
Thus, in this embodiment, the step S1 is used to store the to-be-played command, so as to avoid the requirement of manual immediate input; the playing time and the like are packaged through the data of the instruction to be played, so that the playing equipment plays the instruction to be played at regular time according to the playing requirement, and the playing requirement is met. Therefore, the playing time, the playing times and the playing content are packaged into the instruction to be played, so that the playing requirement is input in advance, and the playing requirement can be read and executed intelligently through the playing equipment.
In the specific implementation, step S2 can be divided into the following steps.
And S21, analyzing the command to be played and extracting the playing time.
In this step, the command to be played in the form of 16-ary ASCII code is restored by parsing the character string, thereby obtaining the play time, the play frequency, and the play content.
S22, judging whether there is a command to be played when the playing time is reached.
S23, yes, the instruction to be played that has reached the playing time is obtained as the next playing instruction.
And S34, if not, the instruction to be played with the latest playing time is taken as the next playing instruction.
By combining the step S22 and the step S3, the next playing instruction is pre-extracted, and the timing playing of the next playing instruction is realized according to the playing time after the next playing instruction is determined, so as to further meet the time requirement of the instruction to be played.
In step S1, the command to be played further includes a priority. In step S23, when the plurality of instructions to be played have reached the playing time, the next playing instruction is selected according to the priority. Therefore, when a plurality of instructions to be played wait for playing, the playing sequence can be further defined, and signal crosstalk is avoided.
Specifically, when the priorities of the plurality of to-be-played instructions that have reached the playing time are the same, the next playing instruction is randomly selected, or the to-be-played instruction with the earliest playing time is selected as the next playing instruction.
In a specific implementation, since there may be a plurality of commands to be played that have all reached the playing time, the remaining playing time of the command to be played may be overtime after one play. At this time, the instructions to be played can be reordered according to a preset selection principle of the next instruction to be played; or the information of the command to be played can be sorted and the preset contact can be informed to be manually processed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention are equivalent to or changed within the technical scope of the present invention.
