1Being alternately distributed into 360 ° is distributed on this pcb board 40.The difference of the present invention and traditional control azimuth switch electrode is, the present invention joins the notion of area in the middle of the design, when the user presses this orientation switch rocking bar along a certain orientation, can make the conductive material of flexible member 30 lower surfaces touch orientation switch X
1～X
nIn a switch even more switches and public electrode Y
1, form the state of closed conducting, make rocking bar when pressing down and the orientation switch do the pressing of area formula.Judge and carry out area,, calculate the new orientation that vernier moves and the judgement of speed in conjunction with the program design of being correlated with according to the position of the switch of closure and number.The angular bisector of the sectorial area of pushing down is new orientation, and the area of pushing down is big more, and speed is fast more.Simultaneously, the time counting that switch is pushed down continuously adds 1, when counting greater than certain preset value, second section acceleration is set, and has overcome traditional accelerationless shortcoming of control azimuth switch rocking bar.
The operation of vernier is except the moving of orientation, and the speed that moves also is an important research project.Add the design concept of area when gauge tap after, the power that rocking bar presses down can present with the form of area, and by relevant program design area is judged, vernier is moved with different speed on screen.Add if the user wishes must allow rocking bar rest on identical seat a period of time, and these information also can make vernier do accelerated motion by program design toward this orientation fast moving.Therefore, the present invention is not limited to PCB layout method as shown in Figure 3, and other devisers also can design according to the present invention make other variation, and these variations also all should belong to protection scope of the present invention.
According to orientation of the present invention switching regulator rocking bar, the present invention also provides a kind of method of azimuth scan.As shown in Figure 4, it is the process flow diagram of this azimuth scan subroutine, and this method comprises the following steps:
(a) user presses this orientation switching regulator rocking bar along a certain orientation with certain dynamics, thereby makes flexible member press down, and contacts with the pcb board of its below;
(b) call the state that the port scanning subroutine is read in each switch, judge the public electrode on lower surface that flexible member on this orientation is coated with conductive material and the pcb board and the situation that contacts of each orientation switch, also the i.e. situation of the contact area size of flexible member and pcb board on this orientation;
(c) judge whether switch has closure, promptly whether the flexible member lower surface all contacts with public electrode and orientation switch, forms conducting state; If do not have closure, then remove the time counting that present speed and switch are pushed down continuously; If closure is arranged, then judge and calculating make new advances orientation and speed and preserve more new data; Its method of judging new orientation is: the number of compute switch closure, carrying out area judges, promptly judge the position and the number of the switch of conducting, and then judge the size of contact area by the conducting situation of public electrode on flexible member lower surface and the pcb board and orientation switch; Conducting number multiaspect more is long-pending big more, illustrates that pressure is big more, and speed should be fast more; And the angular bisector of the sectorial area of being pushed down is new mobile orientation; Its method of judging new speed is: the time counting that switch is pushed down continuously adds 1, when counting greater than a certain preset value, second section acceleration is set; Draw final orientation and speed according to above method, preserve current speed, remove and quicken sign; And speed and orientation moving cursor according to this.
(d) return master routine.
By the present invention, can make user's operation simpler, avoided the photovalve of traditional trace ball need consume more high-power, vectorial element and caused that cost increases, the orientation switch can only the accelerationless again shortcoming of constant bearing.As Fig. 5 and shown in Figure 6, it is the power consumption situation synoptic diagram of traditional trace ball power consumption situation and foundation orientation of the present invention rocking bar, as can be seen, traditional trace ball running current is about 25mA, about time 30ms, and working current reaches 7mA during standby, and the time is about 5 minutes, so power consumption can be very big; And the working current of foundation orientation of the present invention switching regulator rocking bar is about 7mA, and about time 30ms, standby current is about 2mA, and the time is about 4 seconds.Thus, littler than traditional trace ball according to the working current of orientation of the present invention switching regulator rocking bar, stand-by time is also short, therefore more power saving.
Be understandable that; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and these all changes and distortion all should belong to the protection domain of the appended claim of the present invention.
