Fig. 3 is the inductive switch trigger theory figure that charge bar shown in Figure 1 produces 17 signals, in keyboard base 14 corresponding each orientation an inductive switch 13 is arranged, the keyboard base 14 of accusing below, bar 11 bottoms also is provided with an inductive switch 13, accuse that bar middle part and its bottom all are provided with an inductive switching district, after will accusing that switch toggles it to corresponding orientation, the induction zone at charge bar middle part and the inductive switch in this orientation interact and send an electric signal, the charge bar is got back to the null direction automatically after confirming, promptly do not trigger the position of any switch, electric signal comes into force; After will accusing that bar toggles it to a certain orientation, produce an electric signal, then push downwards, accuse that the inductive switch of bar below is triggered, send the another one electric signal simultaneously, confirm back charge bar self-zeroing position, electric signal comes into force.Accuse that bar is pushed the inductive switch that triggers this position downwards at medium position and also can be sent a corresponding electric signal, the difference action of each charge bar can be exported 17 kinds of different electric signal equally like this.Accuse that bar pushes any orientation (comprising the null direction) and can both be pressed.Certainly, can also optoelectronic switch be set, match with the different actions of accusing bar and send different electric signal in each orientation.

Fig. 4 is eight locations drawing that the direction trigger switch is triggered seeing from the top, by among this figure as can be seen, no matter take which kind of triggering mode, always each accuses that bar can produce 17 different electric signal.

Fig. 5 is a control bar signal output synoptic diagram, foregoing 17 kinds of different control bar signals are output, solid line among the figure is represented the electric signal output line after each orientation trigger switch is triggered, dotted line is represented the electric signal output line after the trigger switch of each below, orientation is triggered, heavy line is represented ground wire or supply lines, is used for finishing coming and going of electric signal.17 kinds of signals can be the digital signals 0 or 1 of different voltage representatives.When the control bar triggered one of them or triggers two switch output signals simultaneously, its signal output can be 0 or 1.Signal 0 or 1 can be represented and be triggered or be not triggered.When trigger pip output had been represented triggering with 0, its heavy line was just as supply lines, and supply lines voltage can be different; When trigger pip output had been represented triggering with 1, its heavy line was as ground wire, and line voltage signal can be different.

Fig. 6 is the electronic component of single control bar and electronic equipment, the connection diagram of processing unit, and the A among the figure represents that a variable zone connects, and all outputs of control bar can maybe needn't be connected to the a-quadrant.In the a-quadrant resistance can be arranged, electric capacity, exclusion, IC and other relevant electronic package.After the a-quadrant, all signal wire outputs are connected to the treating apparatus of portable electric appts, and the output line number that is input to treating apparatus through the a-quadrant can change to some extent.Ground wire among Fig. 5 or supply lines are if during supply lines, and this line can directly or indirectly not linked described treating apparatus; If during ground wire, generally speaking, all can there be direct or indirect the connection with treating apparatus.

Connection when Fig. 6 only lists a control bar, if adopt two control bars, all output electrical signal lines all are connected to a treating apparatus, and can connect two described a-quadrants simultaneously.

Treating apparatus adopt any technical scheme of the prior art all can, it can comprise A/D conversion equipment, interface circuit, storage unit and processing unit etc., the type of modules of processing unit can be:

MCU(RISC，CISC...etc)

CPU

Computing machine

Control panel (Control Board)

PLC

Logical processing unit (Logic Unit)

IC

PAL, GAL... etc.

The topmost effect of processing unit module is the electric signal of handling indirectly or directly being exported by the control bar.

Introduce the disposal route of processing unit below:

Processing unit can adopt reflection corresponding (MAPPING), and logic (LOGIC) is analyzed, and the method for condition analysis is come the processing signals input, just can obtain desired result after the processing.

Processing unit carries out logical operation or programming to all input signals, and utilizes the corresponding relation between coding setting signal and the character display.When the user begins to stir the charge bar, because the principle of state machine (STATE MACHINE), the logical OR program just enters " state that the user imports ", when accusing that bar returns zero-bit, all signals are not triggered, the logical OR program of setting just can be confirmed last input in advance, and shows corresponding character according to concrete coding situation in display.When after the user stirs the charge bar, continuing to push downwards again, stir and produce a signal, push downwards and produce simultaneously a signal again, two signals are arranged simultaneously, confirm that the back user lets go naturally, accuse that bar returns zero-bit, without any triggering, at this moment in display, show corresponding character according to this twice input signal of logical OR program validation of setting in advance, and according to concrete coding situation.Before the user does not let go, accuse that promptly bar does not return before the zero-bit, display does not have shown, and the user can make any change.

The method that described reflection is corresponding can define unlike signal input mapping and specific character representative, thereby obtain corresponding results with form reflection corresponding (TABLE MAPPING) in the form.See table:

Upper left	On	Upper right	A left side	In (pressing)	Right	The lower-left	Down	The bottom right	Representative
													X	X					A
				X					D
															X				F
		X		X					T
										X									W
Also have other situation, do not enumerate one by one at this

Wherein the X-representative has the signal of induction

The example of the correspondence of more than just videoing.

When only with a control bar, its reflection corresponding tables has only one, but when with two control bars, corresponding tables just can change to some extent comes correspondence.

Logic (LOGIC) analysis generally is to use AND, OR, and the logic gate of NOT.. etc. (LOGICGATES) or programming process, and example is as follows:

With door (AND GATE)

More than just one of them logical calculation method obtain the example of conceivable character.

Condition analysis generally is that the program that the relevant processing module of utilization is accepted is made relevant condition analysis.Program can be C/C++, VB, Java, Assemble, programming tool that macro...etc etc. are different or language.

For example: if ((upper right have induction) and (there is induction the below, middle part))
