Detailed description of the invention
Below in conjunction with drawings and Examples, the anti-theft control device of the Electrical Bicycle based on winding short circuit of the present invention and control method are described in further detail.
As shown in Figure 1, for control setup constructional drawing of the present invention, three sections of outputs of three-phase bridge type converter connect the three-phase windings of brshless DC motor, the hall signal that brshless DC motor exports connects micro controller system, the output of micro controller system connects the control end of each power tube in three-phase bridge circuit, and micro controller system is MOS6, MOS1 by the power tube cycle of opening in three-phase bridge type converter; MOS1, MOS2; MOS2, MOS3; MOS3, MOS4; MOS4, MOS5; MOS5, MOS6; MOS6, MOS1 ...
Suppose that the brushless DC motor rotor of Electrical Bicycle has p to magnetic pole, three-phase bridge type converter is made up of 6 power tubes, and the hall signal so exported has 6 kinds, and a circle is divided into 6 sectors, 60 degree, each sector.The hall signal state gathered often changes once, and count results N just adds 1.According to principle, hall signal is through one-period, rotor turns over a pair magnetic pole (such as, rotor p is exactly that rotor turns over 360/p degree electric angle to magnetic pole), so hall signal state often changes once, (360/p)/6 degree electric angle that rotor turns over, if know that wheel diameter is D, can calculate and be moved distance.
Composition graphs 1, Fig. 2, Fig. 3 and Fig. 4 describe the control method of anti-theft control device of the present invention, specifically comprise the following steps:
1, user closes Electrical Bicycle and pulls up key, battery-driven car power cut-off, and under being in parking mode, micro controller system pin P1.0 sets high level;
2, the hall signal that sends of micro controller system sampling brshless DC motor, micro controller system pin P2.0, P2.1, P2.2 receive hall signal;
3, micro controller system starts to count N, and when hall signal changes, count value N adds 1; When hall signal does not change, repeat step (2),
4, according to counting N, calculate and be moved distance:
If 5 are moved distance do not exceed warning value H, repeat step (3);
If 6 exceed warning value H, then micro controller system pin P0.1, P0.3, P0.5 output pulse signal makes bridge three power tubes conducting simultaneously under three-phase bridge type converter, brshless DC motor three-phase windings short circuit;
7, during brshless DC motor three-phase windings short circuit, brshless DC motor can not rotate under application force outside, reaches the effect of electric vehicle anti-theft.
The security method of the above-mentioned Electrical Bicycle based on winding short circuit and control setup, only by detection hall signal, calculate be moved Distance geometry warning value H and compare according to algorithm, by brshless DC motor three-phase windings short circuit, so that can not rotate under application force outside, reach the effect of electric vehicle anti-theft.
