Technology sharing | broadcast function design in integrated dispatching

summary

In the integrated scheduling system , Broadcasting can be divided into text broadcasting （ Message broadcast , With receipt function ）、 Real time voice broadcast （ A shouting broadcast ）、 And media broadcasting .

Depending on the type of broadcast ： We also divide radio into Message type and Streaming media type , Message type Namely Text broadcast type ; Real time voice broadcast as well as Media broadcast Is the type of streaming media .

There are receipt status types Namely Text broadcast , No receipt status type Namely Real time voice broadcast and Media broadcast type .

• Text broadcast ： Send a text broadcast to the system or a group , Users who receive the broadcast , A prompt box will pop up in the system window , Let online users check broadcast information in time .

• Real time voice broadcast （ A shouting broadcast ）： This function is similar to broadcasting to find people , In case of an emergency , This function can effectively cross the group limit , Make voice call notification to the designated person or the person in the organizational structure .

• Media broadcast ： This function is similar to background music broadcasting , Without affecting the intercom channel , Play background music .

Demand analysis

Considering the expandability of the system structure and the decoupling between modules in the system , We need to consider the following scenarios ：

1、 Flexible grouping ： On the radio , Fast regional broadcasting or full staff broadcasting is required , We need built-in preset group function , Group regional users or all users in advance , It is convenient to distribute broadcast tasks in these groups .

2、 Timing task ： On the radio , There will be a need to send some broadcasts regularly ： Besides the real-time voice broadcast we mentioned above （ A shouting broadcast ）, It cannot be timed out , Both text broadcast and media broadcast can be broadcast at fixed time . The scheduled broadcast only needs to be sent at the specified time , You can also add a periodic task to the scheduled task ： For example, this broadcast is sent at this time every day , Or send this broadcast at this time every weekday .

3、 Perform receipt statistics for text broadcast , Text broadcasting is similar to system announcement notification , The dispatcher needs to know , Current broadcast , How many people have seen , And the time to see the announcement .

4、 Manage broadcast tasks ： Pause or end the broadcasting task .

5、 For existing broadcast tasks , You can reuse , Quickly create broadcast tasks .

6、 Media broadcasting is like playing music ： Sometimes the dispatcher wants to use the recorded data for regular broadcasting , So when creating a media broadcast task , You can record locally , Broadcast the recorded sound regularly .

According to the above requirements , We divide broadcast functions into ： Broadcast records 、 My radio 、 Preset group 、 Create four broadcast modules .
