In addition, consider that the strength of transmitted signals of each bluetooth bracelet may not be identical, for above-mentioned steps 132, the account form of the distance between a kind of bluetooth bracelet and each wireless transmission steady arm be provided below further, specifically comprise:

Step 1321, by following formula: Distance=, (c+b × Math.pow (ratio, a)) × ressiCorrection, calculates the distance between bluetooth bracelet and each wireless transmission steady arm;

Step 1322, according to the distance calculated, determines the wireless transmission steady arm that bluetooth bracelet described in current distance is nearest;
