Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
In the present embodiment, for washing machine touch control screen, it is described in detail for this method of toch control.
As it is shown in figure 1, in touch method of the present invention, touch pad mainly comprises: touch screen unit, memory element and control unit, touch screen unit comprises again the operating area of function or procedure Selection and two detection unit.
Wherein, as shown in Figure 2, two detection unit include two test points of A, B respectively, function on touch screen or procedure Selection operating area is touched and the vibration that causes in order to detect user, two detection unit detection oscillation points are transmitted to time value and/or the time difference of described two test points of A, B, and the numerical value detected are sent to control unit simultaneously.
After control unit receives the numerical value that said two detection unit sends over, contrast with the standard figures prestored in memory element, find the coordinate information that oscillation point is corresponding, so that it is determined that the particular location of user operation point and corresponding function or program, carry out respective response, it is achieved function or program are arranged.
Adopt the touch control mode of this vibration detection, it is to avoid by the interference of electric field etc., accuracy of detection is high, as long as and touch touch screen and produce vibration, can detect, means and instrument by touching are not limited, extremely easy to use.
Time according to the different oscillation points propagation distance to two test points of A, B and propagation is different, and the numerical value prestored in memory element is subdivided into three parts, in order to improve detection speed and precision.
Part I is the time difference that after described A test point first receives vibration wave, described B test point receives vibration wave again, and corresponding function or program；
Part II is the time difference that after described B test point first receives vibration wave, described A test point receives vibration wave again, and corresponding function or program；
Part III is the reception time value (non-temporal is poor) that two test points of described A, B are simultaneously received corresponding to vibration wave, and corresponding function or program.
Because the operation point that user is on the touchscreen is not a point, but a region, so, in the memory unit, the regional location of each function or procedure Selection operation is to transmission time of two test points of A, B, one scope must be set according to the size of operating area, this scope can be configured previously according to the practical situation of touch screen, and storage is in memory element, so, not only can improve the convenience of use, the operation easier of user can also be reduced simultaneously.
As in figure 2 it is shown, two test points of A, B to be formed the line segment of a level, in the present embodiment, it is two test points of A, B are arranged on touch screen the upper right corner and left upper, naturally it is also possible to the middle both sides of touch screen or other position of left and right inferior horn are set.
In the line segment center that two test points of A, B are formed, it is assumed that a vertical line is as demarcation line, and whole touch screen is divided into three parts by this demarcation line, respectively on the left of demarcation line, on the right side of demarcation line and demarcation line.
As seen from Figure 2, when touching the function on the left of demarcation line or procedure Selection operating area (such as 1, etc.) at 2, vibration wave will first arrive at A test point；And when touching the function on the right side of demarcation line or procedure Selection operating area (such as 5, etc.) at 6, vibration wave will first arrive at B test point；When touching the function on demarcation line or procedure Selection operating area (such as 3,4 etc.), vibration wave will arrive at two test points of A, B simultaneously, but touches 3,4 regions respectively, and the time arriving at 2 is different.
So, in this control method, for the operation point being positioned on the left of demarcation line on touch screen and on the right side of demarcation line, adopt the mode of reduced time difference to be distinguished；And be pointed to the operation point on demarcation line, then adopt the mode of reduced time value to be distinguished.
Due in vibration wave communication process, when running into the prevention of other object (such as edge), vibration wave can reflect, so, detection propagation must be as the criterion with the time that two test points first times receive to the time of two test points of A, B, to improve accuracy of detection further.
If in two test points of A, B, only one of which test point receives vibration wave, and another test point does not receive vibration wave, then be judged to inefficacy, do not carry out follow-up judgement, it is to avoid misoperation.
As it is shown on figure 3, concrete detecting step is as follows:
(1) washing machine powers on start.
(2) user touches function or procedure operation unit, selects required function or program.
(3) two detection unit detect shake-up, start timing.
(4) when operating area on the left of user touches demarcation line, after shake-up being detected, two detection unit start timing, if A test point is firstly received vibration wave, timing before then resets and restarts timing, until timing stops after B test point receives vibration, this time value is the oscillation point propagation time difference to two test points of A, B, and the information that this time difference and A test point first receive vibration wave is sent simultaneously to control unit.
When operating area on the right side of user touches demarcation line, after shake-up being detected, described detection unit starts timing, if B test point is firstly received vibration wave, timing before then resets and restarts timing, until timing stops after A test point receives vibration, this time value is the oscillation point propagation time difference to two test points of A, B, and the information that this time difference and B test point first receive vibration wave is sent simultaneously to control unit；
When user touches the operating area on demarcation line, two test points of A, B are simultaneously received vibration wave, then be sent to control unit by touching the time value started to reception stops, and the information simultaneously issuing control unit has two test points of A, B to be simultaneously received vibration wave.
(5) data prestored in the data received and memory element are contrasted by control unit, find corresponding coordinate information after contrast, so that it is determined that the particular location of user operation point and corresponding function or program.
(6) function or program response, it is achieved user arranges requirement, washing machine runs by function or the program of user's setting, completes whole laundry operations.
For improving the response sensitivity of touch screen, avoid the problem that the operation point caused owing to using the touch screen material caused to deform for a long time deviation occurs to detection cell position, the present embodiment arranges self-calibrating module in a control unit, touch screen is also correspondingly provided with viewing area, user or be operated by this region enter self-calibrating pattern, user is operated according to information.
User is according to information, touch the operation point of each function or procedure Selection operating area respectively, the time value detected and time difference are re-entered in memory element and are stored by two detection unit, the method of detection time value and time difference is same as above, after total data storage completes, automatically exiting from self-calibrating pattern, when using, control unit will contrast with the new data of storage in memory element next time.
As it has been described above, in conjunction with the plan content given by accompanying drawing, it is possible to derive similar technical scheme.In every case it is the content without departing from technical solution of the present invention, according to any simple modification, equivalent variations and modification that above example is made by the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
