Set up the 3rd group of hyperbolic curve C1, C2, the hyperbolic curve that it forms for the range difference D3 of distance between F character and sound wave sensor device S1, S3, wherein Y3 is the center line of sound wave sensor device S1, S3 present position, and the straight-line equation of Y3 is x=0, and the Hyperbolic Equation of C1, C2 can be expressed as:
Wherein, a
3Be D3/2, b
3 2Be c
2-a
3 2
And these 3 groups of hyperbolic curve A1A2, B1B2, C1C2 intersect at intersection point K1, K2.
3 groups of hyperbolic curve A1A2, B1B2, C1C2 of 155 pairs of foundation of processing unit ask for it and separate jointly, and then this separates the intersection point K1 that is these three groups of hyperbolic curves and intersects, the coordinate figure of K2 jointly.I.e. three equations to setting up:
Ask for the x, the value of y, the i.e. coordinate figure of K1, K2 that are fit to simultaneously.Because in actual applications, input face 10 only may be positioned at a position at one time, and therefore, the F character only may be positioned at these three groups hyp one of them intersection point, for example in two intersection points of K1, K2.So computing unit 1513 is only chosen among three groups of hyp intersection point K1, K2 the coordinate figure of the coordinate figure of any one as the F character, and processing unit 151 is stored to storage unit 153 with the coordinate figure of the F character chosen.
After the coordinate figure of F character was finished in computing unit 1513 storages, the look-up table in storage unit 153 was searched and the coordinate figure corresponding characters, and the ASCII character encoded radio of this character correspondence, and wherein the ASCII of this F character is encoded to 01000101.Computing unit 1513 exports it to information output unit 17 read the ASCII character 01000101 of F character in storage unit 153 after.
