The embodiment of the present invention seven are as follows:
The present invention in the specific implementation process, since bluetooth equipment power is limited, is able to carry out a certain range of position
Positioning, so applying in practical campus scene, can focus on cloth and be placed on the key positions such as school gate, classroom, student dormitory, thus
Monitoring student attends class situation to school.
Concrete scheme is as follows:
S1: for example in school gate, tri- beacon Bluetooth base. stations of AP1/AP2/AP3 are arranged in school gate region
S2: it is reached near school gate when student adorns oneself with bracelet, tri- base stations Bluetooth base. station AP1/AP2/AP3 just will receive this
The Bluetooth signal of student's bracelet.
S3: the position of each base station distance student has and far has closely, so the signal strength received is different, just according to algorithm
It can determine the location of current student.Specific calculating process is as follows:
(1) after each base station receives the signal of bracelet equipment sending, since bracelet equipment is different apart from base station distance,
The signal strength received also can corresponding difference, back background server, server root are passed this data of signal strength in base station
According to signal strength, the distance of user distance base station is assured that according to signal strength.Referring to figure 3., specific formula for calculation is such as
Under:
D=10^ (abs (RSSI)-A)/(10*n)
Wherein d is to calculate resulting bracelet at a distance from Bluetooth base. station, and abs (RSSI) is the absolute of signal strength (negative value)
Value, signal strength when A is bracelet equipment and 1 meter of Bluetooth base. station distance, n is the environmental attenuation factor.
So user may be in any point on this circle of C1.
(2) three base stations just can determine that tri- range rings of C1/C2/C3, and it is exactly current user that these, which enclose common intersection point,
The location of (bracelet equipment).There may be some errors for calculated distance, but in actual use, monitoring student from
Outside school enter campus, precision can receive without too high.
S4: when student is entered into bracelet outside school gate as during this, background application can be received constantly in school gate
The signal strength passed back to base station obtains motion profile, to learn whether student has entered to continuously judge student position
School.After judging student to school, background system can send to parents of student and notify on this basis, inform student
To school.
Likewise, this mode can also apply to classroom, student dormitory etc. emphasis place.Although this programme single base station
The effective position range of group is small, but in campus-wide, can be by arranging multiple base station groups in different zones, to monitor
The raw activity trajectory in campus.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
