Abstract
The invention relates to a touch device testing method. A touch panel, a metal pen, a computer and a signal generator are utilized. Coordinate data generated by the movement of the metal pen on the touch panel is recorded, thereby calculating offset, and the performance of the touch panel under the conditions of interference signals is finally judged. The touch device testing method provided by the invention is simple; and by the method, the anti-interference performance of a touch device can be rapidly and accurately judged, and the conventional shortcoming that touch stability cannot be evaluated effectively is overcome.
Description
Technical field
The present invention relates to the correlative technology field of touch-control, particularly a kind of method of testing of contactor control device.
Background technology
At present, continuous development along with electronic product, the contactor control device series products becomes the main direction of future development, and the still not present common hand-held computer of people adopts full touch-control scheme, even the ATM (automatic teller machine) of some banks also provides the Touch Screen that can directly touch operation for the user.Following continuous development along with science and technology, we can touch the touch-control product everywhere in the field of life, so also provide convenient service more for the mankind's life.
Though the contactor control device indispensable a kind of product that is future life, this product are owing to itself be to utilize resistance or principles such as electric capacity or infrared ray to discern corresponding gesture, so also can be subjected to extraneous interference unavoidably.Capacitive touch device relatively more commonly used in the market, because just touching, it can respond to, not only easy to use, and also finger does not does not wear and tear with contacting almost of touch screen, advantage such as stable performance, long service life is so capacitive touch device is present stage to adopt more scheme.But this scheme also can be subjected to the interference of external environment sometimes, directly have influence on the use of contactor control device, the situation of worst is that the user points when sliding on contactor control device and can not right judgement go out corresponding gesture operation, so the test before contactor control device uses just seems particularly important.
Therefore need solve above problem for users provide a kind of method of easy test.
Summary of the invention
The actual technical matters to be solved of the present invention is how a kind of method of testing the contactor control device interference free performance is provided.
In order to realize above-mentioned purpose of the present invention, the invention provides a kind of method of testing of contactor control device, utilize contact panel, metal pen, computer and signal generator, its step is as follows: at first, described contact panel is connected with computer, metal pen is connected with signal generator; Then, the opening signal generator power is exported specific undesired signal; Secondly, utilize metal pen moving on described contact panel, write down the coordinate data of its generation; At last, thus judge the performance performance of contact panel under the condition of undesired signal according to the side-play amount that above-mentioned data computation goes out coordinate.
The method of testing of contactor control device of the present invention, not only simple, and can judge the interference free performance of contactor control device fast and accurately, overcome tradition and can not effectively assess the shortcoming that touches stability.
Description of drawings
Fig. 1 is the connecting circuit figure of method of testing of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
It is described to please refer to Fig. 1, contactor control device of the present invention comprises contact panel, in order to test the interference free performance of described contact panel, at first described contact panel 12 is linked to each other with computer (not indicating), then a metal pen 11 is connected with signal generator 10 by lead, and described contact panel 12 and signal generator 10 are altogether.Described oscillograph can provide multiple signal source after energising, as white noise, sine wave signal, square-wave signal etc.Because metal pen 11 links to each other with signal generator 10, so when metal pen 11 slides, just can import corresponding signal on described contact panel on described contact panel 12, this moment, the function of described metal pen 11 was exactly the effect of analog subscriber finger.
When described metal pen 11 slides on described contact panel 12, because this moment, metal pen 11 connected described signal generator 10, so the signal source that produces on the described signal generator 10 just has been added on the metal pen 11 by lead, described like this metal pen 11 just can move on described contact panel by the analog subscriber finger.Because described contact panel 12 is connecting computer, and is provided with corresponding testing software in the computer, whether normally this software have detection coordinates information function.So, just can detect the coordinate information that metal pen 11 produces when mobile automatically on described contact panel 12 by described software, thus reflect described contact panel 12 under undesired signal whether also in operate as normal, in order to the stability of assessment touch etc.The white noise that produces with signal generator is that example specifies its method of testing below:
At first test circuit figure is connected according to the described method of Fig. 1; The power supply of opening signal generator 10 then, output is the undesired signal of signal source with the white noise; Because the frequency instability of the signal source that under white noise, produced, height is arranged, low voltage amplitude is arranged so just formed.Utilize metal pen 11 on described contact panel 12, to move then; Common method is to draw straight line or circle on contact panel 12.The data that collect when secondly, utilizing the above-mentioned metal pen 11 of software records in the computer to move; The above-mentioned data of ultimate analysis also calculate the coordinate offset amount that above-mentioned data produce.If above-mentioned coordinate offset amount in the preset threshold value, thinks that then described contact panel has good stability under the condition of undesired signal; If described coordinate offset amount is in described preset threshold value, then think described contact panel less stable under the condition of undesired signal.Described preset threshold value is an empirical value, is the result that correlation engineering teacher draws through repetition test.
The method of test contactor control device antijamming capability of the present invention, not only simple, and can judge the interference free performance of contactor control device fast and accurately, overcome tradition and can not effectively assess the shortcoming that touches stability; Moreover the equipment that this method used is signal generator and computer just, so less testing apparatus has also been saved cost to a great extent.
