Embodiment
The invention provides a kind of portable digital equipment and input method thereof, can replace the button of prior art to import by detecting its motion state, thereby strengthen its portability and operability.
Seeing also Fig. 1, is the theory diagram of portable digital equipment of the present invention.Described portable digital equipment comprises pick-up unit, data processing equipment, user interface and supply unit.Wherein, described pick-up unit is finished the sampling to the equipment moving state, is used for the motion state of checkout equipment, and produces output signal according to described motion state; Described data processing equipment is resolved aforementioned output signal, and converts thereof into corresponding operation signal; Described user interface is used for the information of display device and the result of data processing equipment; Described supply unit is used to whole portable set that working power is provided, and can be self-powered or external power supply.
Seeing also Fig. 2 to Fig. 7, is a kind of embodiment of portable digital equipment of the present invention.
With reference to figure 2, described pick-up unit adopts the MMA series acceleration transducer of motorola inc, and described MMA series sensor has types such as single shaft and twin shaft and 3.Described acceleration transducer is used in a lot of equipment of industry control, is comparatively ripe product.
Described acceleration transducer comprises sensing module (Sensor), signal is carried out comprehensive signal synthesis module (Integrator), signal gain amplification module (Gain), signal filtering module (Filter) and self calibration module (Self-Test), control module (Control), module crystal oscillator (OSC), crystal oscillator gain (Clock) and temperature-compensation circuit (Temp Comp).
Wherein, described sensing module is integrated in IC inside, is used for finishing the motion state sampling to equipment, behind the signal process gain amplification module, by the signal filtering module filtered, exports through behind the temperature-compensation circuit again.Acceleration transducer generally has 2 axial simulating signal outputs.
Described self calibration module also is integrated in IC inside, is used to realize the self calibration of sensor and the output of current state.
See also Fig. 3 and Fig. 4, described sensing module can adopt condenser type, and when portable digital equipment moved, the value of electric capacity changed; And when different moving axially, disalignment to capacitance change.Export behind the gain of signal process amplification module, signal filtering module and the temperature-compensation circuit that sensing module produces.That is to say that 2 axial analog output signal X-Out and Y-Out will change along with the variation of portable digital equipment motion state.
Seeing also Fig. 5, is the combination synoptic diagram of pick-up unit and data processing equipment in the present embodiment.
Because sensor output is simulating signal, for general data processing equipment, can not correctly discern.So can selection itself when selecting data processing equipment have the MCU (microprocessor) of analog to digital converter (A/D), in MCU inside simulating signal is converted into digital signal, and determines present state and the operation of soon carrying out according to the difference of digital signal that collects and default fiducial value.Certainly, also can select to be positioned at the independent analog to digital converter of MCU outside.In addition, also can be at the sensor internal integrated analog digit converter, thus make sensor directly to export digital signal to MCU.
Wherein, the ST of the self calibration module of sensor end is connected to any delivery outlet P1 mouth of MCU, is used for sensing module is carried out self calibration; The Status of sensor end is connected the P0 mouth of MCU, is used for the present state of detecting sensor.Analog output signal X-Out, the Y-Out of the X of sensor, Y direction enters the analog to digital conversion input pin of MCU respectively by the RC filter network.MCU carries out digital-to-analog conversion with the simulating signal of input, obtains digital signal, the operation of determining present state and being about to carry out.
See also Fig. 6, in the embodiment of the present invention, the flow process of the motion state replacing key-press input of employing equipment comprises step: degree of will speed up sensor resets, calibrate by the self calibration module, and each axial magnitude of voltage is converted to digital quantity through analog to digital converter at this moment, as intermediate value (as 0x80), making zero in the similar weighing process of this process.
Acceleration transducer is in certain intervals time (difference that described interval requires conversion accuracy according to each system and difference, have relatively high expectations and to improve sample frequency, the less demanding sample frequency that reduces, in general, the speed of sampling is different because of chip with the speed of conversion.) in, gather each axial magnitude of voltage.
Described magnitude of voltage is converted to digital quantity through analog to digital converter.
To newly collect each axial digital quantity and the intermediate value comparison of axle separately, judge the motion state of current device.
For the ease of understanding the present invention, be described below in conjunction with an embodiment.Present embodiment replaces the input of left and right directions key with portable digital equipment along moving of moving of X-axis.
At first, collect portable digital equipment when static the digital quantity of X-axis be 0x80; Then when the digital quantity that collects now is 0xA0, think that then portable digital equipment moves right; If the digital quantity that collects is 0x20, think that then portable digital equipment is to left movement.
The maloperation that produces for fear of user of service's slight unconscious motion, the output signal that the motion of equipment is produced can be provided with a threshold values, have only the digital quantity that collects of working as equipment greater than this threshold values, judge that then this motion is effective exercise, otherwise judge that motion is invalid.The digital quantity that collects as setting is being nonsignificant digit between the 0x70 to 0x90.
When the direction of motion of having judged equipment, whether be a button to the left or to the right in order to judge that current motion state changes, further carry out following steps:
Carrying out backhaul judges;
Carry out the operation of correspondent button according to the result of backhaul judgement.As, suppose that the previous motion state of portable set is static, there is this moment level displacement left to take place, think that then a button left produces; To the right, current motion state and is not again (the detailed introduction of backhaul is seen below) of a backhaul left, thinks that then a button operation left produces during the preceding state of equipment.
Seeing also Fig. 7, is the synoptic diagram that described backhaul is judged.
So-called backhaul refers to: when equipment after a certain direction moves, suddenly arrestment moves simultaneously round about.
In order to judge that whether certain motion belongs to the backhaul of motion last time, need be provided with retrace interval T in data processing equipment.
The principle that backhaul is judged is as described below: suppose that initial the time, equipment is static, when equipment being moved up (up), thinks that the operation of this moment is that to carry out UP strong, if user's rollback in time t1 then has 2 kinds of situations appearance this moment:
If t1＜=T then thinks a backhaul, be not used as a DOWN key and carry out;
If t1＞T then thinks not to be a backhaul, should make a DOWN key and carry out.
In like manner, up key next time will be reference with previous " DOWN ":
As t2＜=T, then think a backhaul, be not used as a UP key and carry out;
As t2＞T,, then think not to be a backhaul, should make a UP key and carry out.
Certainly, pick-up unit of the present invention is not limited to the acceleration transducer in the aforementioned embodiments, can also adopt and angular transducer.Perhaps the more sensor that now can finish this function of sampling of motion state on the market can use.
The principle of work and the acceleration transducer of described inclination and angular transducer are similar, just the motion state of equipment changes different, but the output signal of sensor itself is similar, controller is to its transfer principle, be that analog to digital conversion is also identical, and inclination and angular transducer and acceleration transducer are to the judgement of button roughly the same.
At this moment, the movement technique of portable digital equipment is to be the center with equipment, about or the front and back tipping arrangement, sensor sends the angle of being rotated to data processing equipment MCU in the mode of voltage or electric current, it is digital quantity through analog to digital conversion that MCU will sample analog quantity, and judge the yawing moment of current device, thereby carry out corresponding action with this.
Be understandable that the present invention adopts the motion state of portable digital equipment to come some buttons on the replacement equipment, make the easier operation of portable digital equipment and carrying.And for portable set, because it was exactly transportable originally, so move (not the needing very strong) of equipment can be to the too big negative effect of performance generation of entire equipment.
And the variation of motion state can adopt some parameters to detect, and comprises that the angle of direction, equipment rotation of equipment moving and/or equipment are moving with specific speed etc.
And the button that replaces finger direction key not only, if the motion state of equipment can represent with linear dimensions, then can be used for representing numerical key etc.
What need further specify is, because portable digital equipment of the present invention adopts the mode of motion to come replacing key-press, institute thinks and prevent maloperation that portable digital equipment of the present invention can also comprise locking device, is used for control and whether motion state is converted to button.Described locking device can be a Hold key or other the flexible mode that increases, and by the Hold key, can carry out the switching between acceleration transducer hang-up and the unlatching.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
