Accompanying drawing explanation
Fig. 1 is the structural representation of position sensor of the present invention.
Fig. 2 is the schematic diagram of position checkout gear of the present invention.
Detailed description of the invention
Below, by reference to the accompanying drawings position sensor of the present invention and position checkout gear are described in detail.
Fig. 1 is the structural representation of position sensor of the present invention.
As described in Figure 1, position sensor of the present invention comprises body 10, conductive core 20, multiple electrode P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P15, P16.Here, electrode is set to 16, and herein only with explaining, electrode involved in the present invention is not limited to 16, can adjust according to precision.
Body 10 can be formed as tubular, and its cross section can be circular, also can be oval or other polygons, such as hexagon etc.
Multiple electrode P1-P16 are inserted in the inner side of body 10, and electrode P1-P16 is uniformly distributed, and also can be non-uniform Distribution.Be preferably and be distribution.In whole electrode, be divided into the first electrode and the second electrode according to its function difference; Such as: P1, P3, P5, P7, P9, P11, P13, P15 are the first electrode, P2, P4, P6, P8, P10, P12, P14, P16 are the second electrode.First electrode connects respectively at signal source, such as 3.3V voltage source, and signal source also can be ground.
Conductive core 20 is arranged on intrinsic movably, freely moves in the space of body under gravity.Conductive core is preferably formed to cylinder or ball, can be metal, also can be other conductive material.Conductive core 20 preferably once can be electrically connected at most two adjacent electrodes, as shown in Figure 1.
When position sensor rotates, under gravity, conductive core 20 moves in body 10, is supported, be illustrated in figure 1 P9, P10 after finally static by the adjacent electrode of two immediately below conductive core 20.In these two electrodes, one is the first electrode, and one is the second electrode, and they are electrically connected by conductive core 20, and like this, the signal of signal source is just output to the second electrode.
Figure 2 shows that the schematic diagram of position checkout gear of the present invention.
As shown in Figure 2, position checkout gear of the present invention comprises position sensor and control unit, here, control unit is preferably single-chip microcomputer, control unit has multiple I/O and holds, multiple second electrodes of position sensor are connected respectively to I/O end, specific in Fig. 2, for P2, P4, P6, P8, P10, P12, P14, P16 is connected to I/O end, like this, when position as shown in Figure 1, the signal of the I/O input signal source be connected with P10, such as 3.3V, because the annexation of the second electrode and I/O is predetermined, so control unit just can determine after receiving signal which the second electrode concrete is contacted by conductive core 20, the position of conductive core can be determined thus, and judge the position of the user that attached to position sensor thus.
