Embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in the following detailed description that cooperates with reference to graphic a plurality of embodiment, can clearly present.Now will be in detail with reference to embodiments of the invention, and the example of described embodiment is described in the accompanying drawings.In addition, all possibility parts use element/member of same numeral to represent identical or similar portions in drawings and the embodiments.
Fig. 1 illustrates the synoptic diagram into the actuation inputting type electronic installation 100 of one embodiment of the invention.Please refer to Fig. 1, actuation inputting type electronic installation 100 comprises input media 10 and back-end device 20.Wherein, input media (input device) 10 comprises two supersonic transducers (ultrasonic transducer) 101 and 103, drive circuit unit (driving circuit unit) 105, receiving circuit unit (receiving circuit unit) 107, diplexer (diplexer) 109, control module (control unit) 111, and transmission unit (transmitting unit) 113; Back-end device (backend device) 20 then comprises main frame (host) 115 and display unit (display unit) 117.
In the present embodiment, supersonic transducer 101 and 103 both driven with transmit separately (transmitting signal) TS1 and TS2 by drive signal DS to come object sensing (object) 30 (for example hand, but be not limited in this).What deserves to be mentioned is that at this supersonic transducer 101 and 103 is to utilize piezoelectric effect, converts electrical energy into mechanical energy earlier, use in air by air vibration, and send outwardly with the compressional wave direction and to transmit as transmission medium.After transmitting of being sent of supersonic transducer 101 and 103 senses object, this vibration wave is reflected, and the mechanical wave that reflects is converted to electric energy (being echoed signal), come existing of object sensing with this principle by supersonic transducer.
In addition, control module 111 is also in order to count first and second Preset Time, all echoed signal ES1 and ES2 that storage receiving circuit unit 107 is judged in each second Preset Time greater than threshold value, storage supersonic transducer 101, in 103 at least one from the transmission TS1 that transmits, the 1st the time that TS2 judges to receiving circuit unit 107 in each second Preset Time greater than the echoed signal ES1 and the ES2 of threshold value, and judge that receiving circuit unit 107 judges in each second Preset Time all greater than the echoed signal ES1 of threshold value and ES2 whether only from supersonic transducer 101, one of them passback of 103.
In the present embodiment, control module 111 can utilize microcontroller (microprocessor) to realize, but is not restricted to this.Thus, 111 of control modules can be counted first and second Preset Time respectively by two timers (timer does not illustrate) of its inside.In addition, control module 111 also can pass through its inner storer (memory, do not illustrate) store all echoed signal ES1 and ES2 that receiving circuit unit 107 is judged in each second Preset Time greater than threshold value, and in the storage supersonic transducer 101,103 at least one transmit the 1st the time that TS1, TS2 judge to receiving circuit unit 107 in each second Preset Time from transmission greater than the echoed signal ES1 and the ES2 of threshold value.Also also because of so, control module 111 can judge that receiving circuit unit 107 judges in each second Preset Time with reference to the data/information that is stored in its internal storage all greater than whether one of them passback of the echoed signal ES1 of threshold value and ES2 from supersonic transducer 101,103.
In the present embodiment, when supersonic transducer 101 and 103 is positioned on the same transverse plane line 201 (as for example Fig. 2 illustrates), then in the object 30 that obtained of control module 111 and the supersonic transducer 101,103 at least the relative motion information between the one include left side mask information, the right mask information, mobile message, mobile message, move left and right velocity information and/or range information from right to left from left to right.Wherein, range information is the distance between the one at least in object 30 and the supersonic transducer 101,103.
Be positioned under the condition on the same transverse plane line 201 based on supersonic transducer 101 and 103, Fig. 3 illustrates the operation workflow figure into the control module 111 of one embodiment of the invention.Please merge with reference to Fig. 1～Fig. 3, control module 111 carries out initializing set (step S301) earlier, then begins to count first Preset Time (for example 0.01 second) to judge whether to reach first Preset Time (step S303) by internal timer (being defined herein as first timer) again.
When control module 111 count down to first Preset Time (judged result of step S303 is a "Yes"), control module 111 is set diplexer 109 earlier for transmitting drive signal DS (step S305), and then control Driver Circuit unit 105 produces drive signal DS and gives diplexer 109 (step S307) again.Thus, diplexer 109 just sends drive signal DS to supersonic transducer 101 and 103, uses to make supersonic transducer 101 and 103 be subjected to drive signal DS driving to come object sensing 30 with the TS 1 that transmits separately with TS2.Yet, if control module 111 no counts are returned execution in step S303 during to first Preset Time (judged result of step S303 is a "No").
When control module 111 control Driver Circuit unit 105 produce drive signal DS, and diplexer 109 has transmitted drive signal DS to supersonic transducer 101 and 103, control module 111 can set immediately diplexer 109 for transmit supersonic transducer 101 with 103 separately the echoed signal ES1 of passback and ES2 to receiving circuit unit 107 (step S309).Thus, receiving circuit unit 107 just begin to judge supersonic transducer 101 and 103 separately the echoed signal ES1 of passback and ES2 whether greater than a threshold value (threshold value).
For instance, Fig. 4 illustrates and is supersonic transducer 101 of one embodiment of the invention and 103 running synoptic diagram.Can know from Fig. 4 and to find out time t

In case control module 111 receives greater than the echoed signal ES1 of threshold value and ES2 (judged result that is step S311 is a "Yes"), control module 111 just begins to count second Preset Time (for example 0.5 second) (step S313) by inner another timer (being defined herein as second timer), and store all echoed signal ES1 and ES2 (step S315) that receiving circuit unit 107 is transmitted greater than threshold value by its internal storage, and supersonic transducer 101,103 from the transmission TS1 that transmits, the 1st echoed signal ES1 and ES2 institute elapsed time (step S317) that TS2 judges to receiving circuit unit 107 in each second Preset Time, that is the time t of supersonic transducer 101 and 103 greater than threshold value

BYet, if control module 111 do not receive any greater than threshold value echoed signal ES1 and during ES2 (judged result of step S311 is a "No"), return execution in step S303.
When control module 111 in the process that storage receiving circuit unit 107 is transmitted greater than the echoed signal ES1 of threshold value and ES2, control module 111 is understood and be judged whether second timer has been counted and reach second Preset Time (step S319).If control module is judged second timer and has been counted (judged result of step S319 is a "Yes") when reaching second Preset Time, then control module 111 can continue judge that receiving circuit unit 107 judges in second Preset Time all greater than the echoed signal ES1 of threshold value and ES2 whether only from one of them passbacks (step S321) of supersonic transducer 101 and 103.Yet, if when control module 111 is judged the second timer no count and reached second Preset Time (judged result of step S319 is a "No"), return execution in step S303.
In the present embodiment, control module 111 can with receiving circuit unit 107 in second Preset Time is judged all greater than the echoed signal ES1 of threshold value with positive logic " 1 " (promptly+1) form is stored in its internal storage, and can with receiving circuit unit 107 in second Preset Time is judged all (promptly-1) form is stored in its internal storage with negative logic " 1 " greater than the echoed signal ES2 of threshold value.Therefore, control module 111 only need be inspected all data that its internal storage is stored, all that can learn that receiving circuit unit 107 judges in second Preset Time greater than the echoed signal ES1 of threshold value and ES2 whether only from one of them passbacks of supersonic transducer 101 and 103.
For instance, inspect all data that its internal storage stores when being all positive logic " 1 " when control module 111, represent that then all echoed signals greater than threshold value (that is ES1) that receiving circuit unit 107 judges in second Preset Time are only from supersonic transducer 101 passbacks; In addition, when all data of storing when the internal storage of control module 111 are all negative logic " 1 ", represent that then all echoed signals greater than threshold value (that is ES2) that receiving circuit unit 107 judges in second Preset Time are only from supersonic transducer 103 passbacks.
When control module 111 is judged all echoed signals greater than threshold value (that is ES1 or ES2) that receiving circuit unit 107 judges in second Preset Time only from supersonic transducer 101 or 103 passbacks (judged result of step S321 is a "Yes"), then control module 111 can obtain a left side or the right mask information, that is: if when control module 111 is judged all echoed signals greater than threshold value (that is ES1) that receiving circuit unit 107 judges in second Preset Time only from supersonic transducer 101 passbacks, then control module 111 can obtain left side mask information, and just this moment, object 30 covered above supersonic transducer 101; Otherwise, when if control module 111 is judged all echoed signals greater than threshold value (that is ES2) that receiving circuit unit 107 judges in second Preset Time only from supersonic transducer 103 passbacks, then control module 111 can obtain the right mask information, and just this moment, object 30 covered above supersonic transducer 103.In addition, control module 111 more can calculate the supersonic transducer 101 of object 30 and passback echoed signal (that is ES1 or ES2) or 103 distance to obtain range information, that is: when obtaining left side mask information as if control module 111, then control module 111 can the further distance of calculating between objects 30 and the supersonic transducer 101 (be time T
A* velocity of sound); Otherwise when if control module 111 obtains the right mask information, then the distance that can further calculate between objects 30 and the supersonic transducer 103 of control module 111 (be time T
B* velocity of sound) (step S323).When in case control module 111 obtains a left side or the right mask information and range information, control module 111 is exported aforementioned input signal INS (step S325) accordingly with regard to a foundation left side or the right mask information and/or range information, is stored in all data (step S327) of its internal storage to return execution in step S303 and remove subsequently again.
Yet, when control module 111 is judged all echoed signals greater than threshold value (that is ES1 and/or ES2) that receiving circuit unit 107 judges in second Preset Time not only from one of them passbacks of supersonic transducer 101 and 103 (judged result of step S321 is a "No"), then the distances calculated between objects 30 and the supersonic transducer 101 earlier of control module 111 (are time T
A* velocity of sound) and the distance between object 30 and the supersonic transducer 103 (be time T
B* velocity of sound), use and obtain range information (step S329).Then, control module 111 according to supersonic transducer 101 and 103 from transmission transmit TS1 and 1 echoed signal ES1 that is received of TS2 to the and the elapsed time T of ES2 institute
AWith T
BAnd the distance between supersonic transducer 101 and 103, to calculate and to obtain move left and right velocity information (step S331).In this definition distance between supersonic transducer 101 and 103 is D, and then the move left and right velocity information that obtained of control module 111 is D/ (T
A-T
B).
Subsequently, control module 111 will be multiplied by a weighted value (weighting value) separately in all echoed signal ES1 and ES2 greater than threshold value that second Preset Time is stored, and use to calculate and obtain from left to right or mobile message (step S333) from right to left.For instance, suppose that all echoed signal ES1 and ES2 greater than threshold value that control module 111 is stored in second Preset Time have 5, and the order of storage is ES1, ES1, ES2, ES1, ES2, and built-in weight array (the weighting array of control module 111, similarly realizing with control module 111 internal storages) words that also store 5 weighted values are (for example: 10,8,5,3,1), then since control module 111 with receiving circuit unit 107 in second Preset Time is judged all greater than the echoed signal ES1 of threshold value with positive logic " 1 " (promptly+1) form is stored in its internal storage, and with receiving circuit unit 107 in second Preset Time is judged all (promptly-1) form is stored in its internal storage with negative logic " 1 " greater than the echoed signal ES2 of threshold value.Therefore, control module 111 is multiplied by a weighted value 10,8,5,3,1 separately with echoed signal ES1 (+1), ES1 (+1), ES2 (1), ES1 (+1), ES2 (1) earlier, that is: ES1 (+1) * 10, ES1 (+1) * 8, ES2 (1) * 5, ES1 (+1) * 3, ES2 (1) * 1, then add up again obtaining an accumulating values, that is: 10+8-5+2+1=16.In this definition earlier if accumulating values greater than 0, then control module 111 can interpretation objects 30 for by brandishing to the top of supersonic transducer 101 top of supersonic transducer 103, that is from right to left; In addition, if accumulating values less than 0, then control module 111 can interpretation objects 30 for by brandishing to the top of supersonic transducer 103 top of supersonic transducer 101, that is from left to right.Therefore, when this accumulating values of control module 111 interpretations (promptly 16) is greater than 0 the time, then control module 111 can obtain mobile message from right to left.In case control module 111 obtains from left to right or from right to left when mobile message, move left and right velocity information and range information, control module 111 is just according to from left to right or from right to left mobile message, move left and right velocity information and/or range information, and export aforementioned input signal INS (step S335) accordingly, be stored in all data (step S327) of its internal storage to return execution in step S303 and remove again subsequently.
The operation workflow of the control module 111 that Fig. 3 disclosed is based on supersonic transducer 101 and 103 and is positioned at the explanation done on the same transverse plane line 201 (that is object 30 is with respect to running about supersonic transducer 101 and 103 relative), if but supersonic transducer 101 and 103 is when being positioned on the same vertical planar line 501 (as for example Fig. 5 illustrates), as then the operation workflow of control module 111 can illustrate as Fig. 6.Please refer to Fig. 6, control module 111 in the operation workflow of Fig. 6 step S601～S621 and S627～S629 still be similar to Fig. 3 respectively operation workflow in step S301～S321 and S327～S329, and difference only is that step S623, S625, S631～S635 in the operation workflow of Fig. 6 is intended to obtain top mask information, below mask information, from top to bottom mobile message, mobile message and move up and down velocity information from the bottom to top, uses and learns that object 30 is with respect to supersonic transducer 101 and 103 operate up and down relatively.Therefore, the explanation that please refer to the operation workflow of Fig. 3 at control module 111 in the detailed description of the operation workflow of Fig. 6 can class be released, so at this and no longer given unnecessary details.
