Description
Technical field
The present invention relates to ZigBee protocol technical field, be specifically related to a kind of square based on ZigBee protocol dance music array.
Background technology
Square dance has brought body-building benefit and spiritual enjoyment, and be often the athletic ground of " body-building " square dance with the little square of the residential neighborhood that crowd density is higher, community resident participation is higher, large to surrounding environment influence.But traditional square dance music rhythm is mainly using high power acoustics as sound source, and this sound equipment is not only bulky, builds difficulty, and in order to meet the needs of every ginseng dancer, establishment officer must export dance music in the mode of high-decibel.Therefore, bring serious noise jamming to surrounding resident family, the social contradications conflict caused thus also occurs often.
Chinese patent CN201410061096 discloses a kind of square dance wireless music system, comprise portable music player and audio wireless reception arm straps, portable music player is provided with wireless launcher, the music that portable music player is play carries out signal transmitting by wireless launcher, wireless receiving earphone receives the music signal launched from wireless launcher on portable music player, all be furnished with an audio wireless with it every dancer simultaneously and receive arm straps, by wireless transmission and reception music signal, allow each dancer clearly can hear music, will music noise be caused to external world to disturb again, be suitable for any square, the places such as community.Generally all can ceaselessly move during square but people dance, such wireless receiving arm straps is burden for motion, affects square dance impression.
Therefore be badly in need of a kind of low noise music playing system not needing user to carry at present, and when meeting GB_22337-2008 social living environment noise emission standard, meet the requirement of square dance.
ZigBee (ZigBee protocol) theoretical traffic rate is 250kbps, and actual content about transmission rate 100kbps can not meet high quality of music communicating requirement, but controls then to have a surplus for music.
The current technology of zigbee does not also reach the accurate location to mobile object, but for fixed position and the location of not movement every day, by closing on the received signal strength indicator (RSSI) of radio frequency, calculates the position of required location.In zigbee network, the engine of positioning radio frequency with known location is called reference node, and needs the node of compute location position to be called node to be measured.Require that the unique information transmitted between reference node and node to be measured is exactly X and the Y coordinate of reference node.Engine of positioning according to X and the Y coordinate received, and combines the RSSI value drawn according to the DATA REASONING of reference node, compute location position.
Sound phase (as) instrument, having another name called acoustical camera, is the special equipment of the sound-filed simulation utilized in Microphone array measurement certain limit, can be used for measuring the position of sound that sends of object and the state of acoustic radiating, and demonstrate image intuitively by cloud atlas mode, namely acoustic imaging is measured.
Summary of the invention
