Half, choose distance between maximum the sensing radius and first Bluetooth base. station and the second Bluetooth base. station of first Bluetooth base. station
Half in smaller value as the first Bluetooth base. station adjust after sensing radius.
9. the Bluetooth base. station distance of reaction regulating system according to claim 6 or 7, it is characterised in that also include：
Memory module, for storing the sensing radius of each Bluetooth base. station, and export.
10. the Bluetooth base. station distance of reaction regulating system according to claim 6 or 7, it is characterised in that described to calculate two
The distance between Bluetooth base. station is specially：
Utilize formulaCalculate the distance between the first Bluetooth base. station and the second Bluetooth base. station RA,
Wherein, (xA,yA) the first Bluetooth base. station coordinate, (xB,yB) be the second Bluetooth base. station coordinate.
