Described mutual capacitance type capacitance touch screen is provided with some intersecting transmission channel TX and receiving channel RX, and described transmitting is led to
Each cross point between road TX and receiving channel RX forms a detection sensing unit that can detect touch signal, described contact surface
Long-pending S can be drawn by calculating the number of some described detection sensing unit touch signal is detected in continuum, and
Described preset value can be then the numerical value n representing detection sensing unit number.
Another object of the present invention is to providing a kind of intelligent waterproof system of mobile hand-held device, it can be in ambulatory handheld
When equipment imprudence is fallen in water, can automatic shutdown immediately, thus reducing mobile hand-held device to damage mistake in water because falling into
The risk of effect, safety is higher.
A kind of intelligent waterproof system of mobile hand-held device is it is characterised in that include：
Touch signal acquisition module, for obtaining touch signal using mutual capacitance type capacitance touch screen；

When, make mobile hand-held device automatic shutdown.
The system of the present invention, can be improved by following scheme：
Also include normal work control module, for when the AD conversion value generating is not less than baseline value, making ambulatory handheld
Equipment normal work.
Described normal work control module, is additionally operable to be less than baseline value in the AD conversion value generating but contact area S is little
In preset value and touch signal disappear when, make mobile hand-held device normal work.
Described baseline value is corresponding AD conversion value when no any object touches mutual capacitance type capacitance touch screen.
Described mutual capacitance type capacitance touch screen is provided with some intersecting transmission channel TX and receiving channel RX, and described transmitting is led to
Each cross point between road TX and receiving channel RX forms a detection sensing unit that can detect touch signal, described contact surface
Long-pending S can be drawn by calculating the number of some described detection sensing unit touch signal is detected in continuum, and
Described preset value can be then the numerical value n representing detection sensing unit number.
The method of the present invention or system, using mutual capacitance type capacitance touch screen obtain touch signal, then generate with acquired
Touch signal corresponding AD conversion value and contact area S, if generate AD conversion value be less than baseline value, illustrate be
Water contacts mutual capacitance type capacitance touch screen, meanwhile, if contact area S is more than preset value, illustrates to contact mutual capacitance type capacitance touch
The water of screen has reached a certain amount of degree, at this time, it is believed that mobile hand-held device has been fallen in water, and automatic shutdown immediately, from
And it is higher because falling into the risk damaging inefficacy in water, safety to substantially reduce mobile hand-held device.
