In the present invention, the information coding sequence of introducing can be used as the reference for effectively distinguishing artificial magnetic field and other magnetic fields, it is contemplated that information coding sequence can carry magnetic field beacon apparatus Input parameter, therefore, terminal device according to magnetic signature it is counter release information coding sequence after, can also therefrom obtain the expression of magnetic field beacon apparatus, so, can accurately determine the position of magnetic field beacon apparatus.
In order to ensure the controllability of artificial magnetic field, in an implementation of the embodiment of the present invention, information coding sequence is converted to magnetic signature for the parameter in magnetic field can be generated by control.On the basis of implementation as shown in Figure 2, it is also implemented as implementation as shown in Figure 3.Wherein, step 1012 magnetic field beacon apparatus encodes information onto sequence and is converted to magnetic signature, can be implemented as step 10121:
10121, magnetic field beacon apparatus encodes information onto sequence and is converted to magnetic signature by least one in control electric current, coil, conduction time and energization interval.
Since magnetic field beacon apparatus is programmable magnetic field beacon apparatus, therefore, the one or more parameters that can be powered in the parameters such as the number of turns, coil radius, coil space position vector angle by control current strength, current direction, conduction time, energization interval, coil, adjust the magnetic induction that each magnetic field beacon apparatus can export, while using magnetic induction loop, conductor and power supply unit come magnetic field controllable in generation time dimension.As shown in figure 4, being the circuit diagram of magnetic field beacon apparatus.Wherein, concatenated switch between coil and control unit can be used for adjusting the number of turns of coil energization.As shown in figure 5, being the connection schematic diagram of magnetic induction loop and power supply unit, the radius of hot-wire coil can be equally controlled with switch.It should be noted that in addition to the magnetic induction that can adjust beacon apparatus output in magnetic field by the way of such as Fig. 4, as shown in Figure 5 the adjustment of magnetic induction can also be carried out using above-mentioned other parameters, it is not limited here.

With reference to information coding sequence mentioned above, by taking sequence carries single character " a " as an example, the information coding sequence that terminal device determines that a certain magnetic field beacon apparatus is sent is speciallyThe magnetic field beacon apparatus is in t0The value of X, Y, Z of the magnetic induction that moment sends are respectively ax0、ay0、az0, in t1The value of X, Y, Z of the magnetic induction that moment sends are 0, in tnThe value of X, Y, Z of the magnetic induction that moment sends are respectively axn、ayn、azn, in tn+1The value of X, Y, Z of the magnetic induction that moment sends are 0.Wherein, ax0、ay0、az0Value and axn、ayn、aznValue be equal to each other, i.e., in t0Moment send magnetic induction in tnThe magnetic induction that moment sends is identical, increases the reliability of information transmission with this.
In embodiments of the present invention, t can be obtained by the way of calculus of differences0Moment is to tn+1The magnetic field beacon apparatus of each moment generates the magnetic induction in magnetic field in moment.Such as: pass throughThe value for obtaining X, Y, Z is respectively ax0、ay0、az0, to obtain t0Magnetic field strength transmitted by moment is respectively a in the value of three axisx0、ay0、az0, and a corresponding unique character " a ", the i.e. mark of the corresponding magnetic field beacon apparatus of information coding sequence are determined according to the value of above-mentioned X, Y, Z.It should be noted that can determine the relationship between multiple groups adjacent signals respectively in order to improve the reliability of information transmission, obtain multiple characters, and choose magnetic signature of the highest character of frequency of occurrence as magnetic field produced by the magnetic field beacon apparatus in multiple characters.
It should be noted that above-mentioned each moment can be spaced an instantaneous value of collected magnetic field signal of sampling at regular intervals by magnetic field detection sensor, in time will later Analog signal discretization obtains magnetic induction corresponding to above-mentioned each moment.Wherein, the acquisition interval of magnetic field detection sensor can be set by user or staff according to the variation degree of magnetic induction, it is not limited here.
Furthermore, in view of character corresponding to a magnetic field beacon apparatus may be multiple, so using also the same available multiple characters of aforesaid way, such as: in a string of information coding sequences, it is divided according to certain intervals, in 100 time slots, every 20 time slots can indicate a character after calculus of differences, every 20 time slots are equivalent to be repeated to have sent 20/2=10 times for the same useful signal, and 5 continuous characters may finally be obtained, this 5 characters are arranged according to the sequencing that information coding sequence generates, also the magnetic field beacon apparatus indicated with above-mentioned 5 characters has just been obtained.
