Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, right in the following with reference to the drawings and specific embodiments
The present invention is described in detail.The collaboration orientation method based on bluetooth equipment and device of the present invention judges phase between different objects
To direction.
Fig. 1 show the overview flow chart according to embodiment of the present invention.By be added between radio blocking in the way of,
So that aerial signal has directionality, then the relative position of the equipment between communicating is judged by communication quality.Work as nothing
Signal quality is best when not stopping between line electric signal, and communication quality can be deteriorated when having blocking, therefore basis
Blocking situation between antenna between signal quality RSSI and antenna calculates the relative direction of equipment room.
It is specifically included：A. coordinate system and central point are confirmed, to being sat with multiple established from the first object of bluetooth equipment
Mark system, coordinate system center are the first object center；B. connection is established between controlled wireless electricity baffle apparatus is set from bluetooth equipment,
Make multiple to be communicated from bluetooth equipment and the specified bluetooth equipment on the second object；C. by adjusting the position of wireless points baffle
It sets, acquires the RSSI value from bluetooth；D. the direction of main bluetooth equipment is calculated by the slave bluetooth equipment of acquisition, main bluetooth equipment
Direction is the direction of the second object.
Fig. 2 show according to embodiment of the present invention spatially arrange multiple baffles medial node schematic diagram.When
Baffle is at the inside of equipment, direction of the maximum directions RSSI between object.One object has node 1,/2/,3/4 4
BLE equipment is respectively for the four direction of positive tetrahedron, and baffle is in inside；Another object has node 5, node 5 and node
It is communicated between 1/2/3/4, the relative direction of main equipment is calculated according to the RSSI of node 1/2/3/4.
Fig. 3 show according to embodiment of the present invention spatially arrange multiple baffles outer side gusset schematic diagram.When
Baffle is at the inside of equipment, direction (such as Fig. 2) of the maximum directions RSSI between object；When baffle is in the outside of equipment
When, the direction of the directions of RSSI minimums between object.Its interior joint 5 is in the corresponding direction of 2/3/4 plane of node.According to node
Relationship between 2/3/4 RSSI can be estimated according to certain algorithm passes through node 2/3/4 from central point to node direction
The position of the point R of plane.Algorithm needs the influence difference according to baffle to RSSI to be adjusted.
Fig. 4 show crosspoint point estimation schematic diagram according to the present invention.According to from R the remoter RSSI in position it is smaller
Rule, in such a way that single order is fitted, algorithm is as follows：
First by taking 2/ node 3 of wherein RSSI higher values such as node as an example, the dotted line calculated on curve L1 meets：
C/b=k1*RSSI3/RSSI2.
A satisfaction is found out from curve L2 again：
C/a=k2*RSSI4/RSSI2.
The direction for the equipment 5 as estimated to the direction of point R from the intersection point for being changed to two curves of L1 and L2.
Wherein k1 and k2 carries out the influence that RSSI is brought according to the opposite baffle and antenna gain between equipment 2/3/4
Amendment.
