When meeting room internet-of-things terminal is not used, its processor 1 quits work, but single-chip microcomputer 8 also continues to work, to keep the continuous timing of clock.When single-chip microcomputer detects that renewal time that the machine sets is with the time consistency of the clock crystal oscillator 13 of the machine, then pass through I2C bus, wakes up processor 1 up, by Internet network, is attached with outside meeting room Internet of Things server, downloads the file needing to update, carry out system update.
The Core Feature of meeting room Internet of things system, it is the waiting time before utilizing meeting to start to play video information, so just the playing flow of video file being explained below: first meeting room internet-of-things terminal one powers on, system will read the advertisement number that should play at once, then play sequence number reading according to advertisement and be built in the video file within meeting room internet-of-things terminal, and play built in video file；In playing process, system can check continually on an interrupt identification of inside.If this interrupt identification requires to interrupt effectively, then explanation has external video to input, and user is desirable for this terminal, needs to interrupt the broadcasting of built in video at once；If interrupt identification is invalid, then continue to play；It follows that can judge whether a built in video file finishes.Without finishing, then may proceed to read video file, continue to play, and circulate interruption detection just now；If a video file finishes, then it is incremented by and plays sequence number variable, to read next video file, and play, then repeat operation above.
It practice, after meeting room internet-of-things terminal electrifying startup, another process can constantly detect whether the second wireless signal module 5 has signal to input.If there being signal to input, then interrupt identification can be forced to be set to effective status, play process detection in have no progeny, broadcasting built in video can be exited at once, then play the video signal received by the second wireless signal module 5.Equally, when the second wireless signal module 5 does not has video signal, then interrupt identification can be resetted, built in video may proceed to play.
In an idle state, first its single-chip microcomputer 8 can obtain the renewal time from internal time registers to meeting room internet-of-things terminal, it is judged that whether the renewal time expires.If it has not, then timer works on；If the renewal time expires, then can generate renewal demand file, and send renewal request to meeting room Internet of Things server.Meeting room Internet of Things server obtain more newly requested after, first have to resolve and update request data, to obtain more newly requested group number, and inquire about server internal data base, it is thus achieved that all meeting room internet-of-things terminals ID of this group, thus judge that this request is the most effective.If invalid, then ignore；If request is effectively, then packing needs video file and the relevant information updated, and generates and updates file, and is sent to meeting room internet-of-things terminal.After meeting room internet-of-things terminal results update file, renewal file to be resolved, it is thus achieved that group number and meeting room internet-of-things terminal ID, if checking is correct, then store built in video, and the write time time depositor of next update；If authentication error, then continue transmission more newly requested.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
