Generation control signal in data receiver center is sent signal by the network control center certain audio player is adjusted and controlled: the first step, data receiver center receiving sensor detects self parameter of audio power amplifier, compare pre-deposit data, judge the whether applicable broadcasting music that continues of self parameter of audio player, if self parameter exceeds the scope of prestoring, by the network control center, send signal at stop audio power amplifier and emm message is provided; If self parameter, in the scope of prestoring, enters second step; Second step, the marking signal of comparison music type and pre-deposit data judgement music type, do not adjust frequency equilibrium distributor circuit in audio amplifier for neutral music and enter the 3rd step; For higher sound music, adjust the high pitch frequency dividing circuit of frequency equilibrium distributor circuit in audio amplifier, promote the gain of high pitch frequency range, to improve the broadcasting decibel value of high pitch frequency range, thereby the high pitch audio frequency component of realization compensation shortcoming enters the 3rd step; For sound music on the low side, adjust the band pass filter of the middle pitch frequency dividing circuit of frequency equilibrium distributor circuit in audio amplifier, promote the gain of bass frequency range, to improve the broadcasting decibel value of bass frequency range, thereby the audio bass composition of realizing compensation shortcoming enters the 3rd step, for large dynamically music, adjust high pitch frequency dividing circuit and the middle pitch frequency dividing circuit of frequency equilibrium distributor circuit in audio amplifier, promote the gain of high pitch and bass frequency range, to improve the broadcasting decibel value of high pitch and bass frequency range, thereby high pitch and the audio bass composition of realization compensation shortcoming enter the 3rd step; The 3rd step, if do not comprise the α frequency of brain wave of 8-13Hz in the music of playing, allows audio player to enter the normal play music stage; If the α frequency of brain wave that comprises 8-13Hz in the music of playing; open special-purpose infrasound microphone device; and adjust the high pitch frequency dividing circuit of frequency equilibrium distributor circuit in audio amplifier; suitably reduce the gain of high pitch frequency range; suitably to reduce the broadcasting decibel value of high pitch frequency range; to reach the health-care effect of α E.E.G the best, and allow audio player to enter the normal play music stage; Described frequency equilibrium distributor circuit is the frequency equilibrium distributor circuit in claim 3;
Audio player is play: after testing for normal audio power amplifier and remote setting the audio amplifier of parameter music is play.
8. the control method of the sound equipment Play System of controlling based on global communications network according to claim 7, it is characterized in that, before described reception signal, also comprise the personalized control signal that investigation user listens to the music, and this personalization control signal is transferred to the network control center store, in order to follow-up personalized control signal adjustment of listening to the music according to user, play music.
9. the control method of the sound equipment Play System of controlling based on global communications network according to claim 8, is characterized in that, the personalized control signal that described user listens to the music comprises that user plays loudness and the music time of music.
10. the control method of the sound equipment Play System of controlling based on global communications network according to claim 7, it is characterized in that, generation control signal in described data receiver center is sent signal by the network control center certain audio player is adjusted with control and also comprised the 4th step, described the 4th step is: the network control center sends the upper limit of signal Long-distance Control music loudness, if user plays the loudness of sound equipment, be applicable to, enter audio player and play the stage; If it is excessive that user plays the loudness of sound equipment, audio player is closed.
