The outfan of collection controller is transmitted by the radio communication device with the customer mobile terminal, by the described first compression
Packet or second compressed data packets are sent to the customer mobile terminal.
In a kind of embodiment of this utility model, also include：Video collector and video data acquiring controller；It is described to regard
The input of the outfan connection teaching collection in worksite device of frequency data acquisition unit, is acquired to the video at teaching scene；Institute
The outfan for stating teaching collection in worksite device is connected with the input of video data acquiring controller, the video data acquiring control
Device processed is according to the acquiring video information for receiving, the data length information of video information, if the data length information is setting
The 3rd data interval, then be compressed using the third compress mode, obtain the 3rd compressed data packets；If the data length
Information is the 4th data interval of setting, then be compressed using the 4th kind of compress mode, obtains the 4th compressed data packets；It is described
The outfan of video data acquiring controller is transmitted by the radio communication device with the customer mobile terminal, by institute
State the 3rd compressed data packets or the 4th compressed data packets are sent to the customer mobile terminal.
Video data acquiring device is acquired to the video information at teaching scene, is transferred to teaching collection in worksite device.Depending on
Frequency data acquisition controller is processed to the video data of field device harvester of imparting knowledge to students, according to video information data length
Information, is set as two data intervals：3rd data interval and the 4th data interval；For the data of the 3rd data interval are adopted
3rd compress mode is compressed；For the data of the 4th data interval are compressed using the 4th compress mode.Video data
3rd compressed data packets and the 4th compressed data packets of compression are transferred to customer mobile terminal by acquisition controller again respectively.Two kinds
Different compress modes, is compressed to the data message of different length.Threeth number relatively short for video data length
According to interval video, the third compress mode compression speed is fast, and corresponding decompression speed is fast, and compression ratio is high；For data length
The audio frequency of the 4th relatively long data interval, the compression of the 4th kind of being specifically designed for property of compress mode improve compression speed, accordingly
Raising decompression speed, it is ensured that compression ratio；The raising of the compression to data, decompression and data compression rate is realized, accelerates number
According to transmission speed.
Preferably, the audio player is sound equipment.
Preferably, the video data acquiring device is photographic head or camera.
Preferably, the customer mobile terminal is mobile phone, flat board or notebook computer.Portable mobile phone, flat board or
Person's notebook computer, facilitates user and uses in different occasions.
Long-distance educational system of the present utility model compared with prior art, its advantage：
Audio data collecting controller is processed to the voice data of the teaching field device collection of input, according to sound
Frequency information data length information, is set as two data intervals：First data interval and the second data interval；For the first data
Interval data are compressed using the first compress mode；For the data of the second data interval are carried out using the second compress mode
Compression.First compressed data packets and the second compressed data packets of compression are transferred to user by audio data collecting controller again respectively
Mobile terminal.Two kinds of different compress modes, are compressed to the data message of different length.It is relatively short for data length
The first data interval audio frequency, the first compress mode compression speed is fast, and corresponding decompression speed is fast, and compression ratio is high；For
The audio frequency of the second relatively long data interval of data length, the compression of second being specifically designed for property of compress mode improve compression
Speed, is correspondingly improved decompression speed, it is ensured that compression ratio；Realize carrying for the compression to data, decompression and data compression rate
Height, speeding up data transmission speed.
