Specific implementation mode
Referring to Fig. 1, the schematic diagram of the touch device 1 provided by the specific embodiment of the invention.The touch device 1
Including touch-surface 151.
Referring to Fig. 2, the Organization Chart of the running environment for underwater touch sensing system 10 of the invention.The underwater touch-control is detectd
Examining system 10 is applied in touch device 1.Preferably, the touch device of waterproof is capable of in 1 system of the touch device, such as has waterproof
The touch device of coating surface.The touch device 1 further includes memory 11, processor 12, environment detecting unit 13, water quality inspection
Survey unit 14 and touch panel 15.In one embodiment, the touch device 1 can also include display screen 16.
The touch device 1 may be, but not limited to, mobile phone, camera, portable media player, tablet computer and
PC etc. has the electronic device of touch function.The environment detecting unit 13 is for example disposed on the touch panel 15
The humidity sensor of surrounding.When the environment detecting unit 13 detects humidity more than a default value, then it is judged as described touch
Surface 151 is touched to be covered with water.The water quality testing unit 14 is, for example, a miniature water quality detection for being embedded in the touch device 1
Device, wherein the detector of the miniature water quality detector is exposed to outside the shell of the touch device 1, when the environment detecting unit 13
When detecting humidity more than a default value, which sends out signal to the processor 12, which generates
Control signal makes water quality testing unit 14 open work, and the detector of the miniature water quality detector detects the liquid on periphery,
And detect the ingredient of the liquid.In one embodiment, the touch device 1 is mobile phone, the water quality testing unit 14
In the receiver side of the mobile phone and the embedded touch device 1.
The underwater touch sensing system 10 is applied in the touch device 1.The underwater touch sensing system 10 includes environment
Detecting module 101, water quality detection module 102, background value acquisition module 103, judgment module 104 and execution module 105.The water
Each function module in lower touch sensing system 10 can be stored in the memory 11, and be held by the control of the processor 12
Row.
The acquiescence of environment detecting module 101 has the characterization touch device 1 to be in the default value in water.The environment is detectd
It surveys module 101 and controls the humidity information that the environment detecting unit 13 detects the touch-surface 151, and according to the humidity information
Judge whether the touch-surface 151 is covered with water with the relationship of the default value.
The water quality monitoring module 102 is for analyzing the state for detecting the water quality.The state of the water quality includes, but unlimited
In：The combination of the acid-base value, pressure, flow strength and temperature of water.
It is current that the background value acquisition module 103 according to the state of the water quality detected obtains the touch panel 15
Background value.
Background value is that touching object is not touched when on touch-surface 151 according to currently practical sampled value and by centainly calculating
The data that method obtains are to calculate the reference value for having touchless generation.When deviateing background value to a certain degree such as current sample values, touch-control
Panel 15 is then thought to touch object, as finger is placed up.Background value is not unalterable, is the ring needed according to system
Border changes and is updated.The update of background value is related to the judgement that touching occurs for touch panel 15, is as calculating touch-control
The most important foundation of coordinate.If background value updates mistake, then to lead to that touching always happens, touch-control does not occur always etc. a variety of to ask
Topic.Therefore, the present invention is by detecting water quality when touch-surface 151 is covered with water, and the water quality by detecting calculates currently
Background value, you can as reference according to the background value being calculated, to the touch on touch-surface 151 that correctly judges
The position of coordinate.
The judgment module 104 be used for by current touch surface 151 touchs sampled value and the background got
Value compares, and is judged as on the touch-surface 151 when the touch sampled value deviates one preset range of background value
There is touch operation.The touch sampled value can be obtained by the touch panel 15.
The execution module 105 is used to execute corresponding touch when determining the when of having touch operation on the touch-surface 151
Operation.
Referring to Fig. 3, to realize underwater touch detection method of the invention using the underwater touch sensing system 10
Flow chart.It should be noted that underwater touch detection method of the invention is not limited to the sequence of following step, and at other
In embodiment, underwater touch detection method of the invention can only include a portion of step as described below, Huo Zheqi
In part steps can be deleted.The function of above each module is carried out with reference to the explanation of each process steps of Fig. 3 detailed
It introduces.
Step S201, the environment detecting module 101 detect whether the touch-surface 151 is covered with water.Specifically, institute
It states environment detecting module 101 and controls the humidity information that the environment detecting unit 13 detects the touch-surface 151, and according to this
Humidity information and the relationship of the default value judge whether the touch-surface 151 is covered with water.
Step S202, when the touch-surface 151 is covered with water, the water quality detection module 102 detects the water quality
State.Specifically, the water quality detection module 102 controls the water quality testing unit 14 and detects the covering touch-surface
The state of 151 water quality.The state of the water quality includes, but are not limited to：Acid-base value, pressure, flow strength and temperature of water etc..
Step S203, the background value acquisition module 103 obtain the touch-control according to the state of the water quality detected
The current background value of panel 15.The background value is reference value when 151 touchless object of the touch-surface is touched.In this reality
It applies in mode, the combination of the acid-base value, pressure, flow strength and temperature there are many water is can save in the memory 11, it is each
Kind combination corresponds to a background value respectively.The background value acquisition module 103 is by the state of the water quality detected and described a variety of groups
Conjunction matches, you can obtains the background value corresponding to the water quality condition detected.In another embodiment, the memory
In 11 can save a calculation procedure, the background value acquisition module 103 by the acid-base value of the water quality, pressure, flow strength and
The parameters such as temperature bring the background value for calculating and being obtained corresponding to the water quality condition detected in the calculation procedure into.
Step S204, the judgment module 104 get the touch sampled value on current touch surface 151 with described
Background value compares, and is judged as on the touch-surface 151 when the touch sampled value deviates one preset range of background value
There is touch operation.Wherein, the touch sampled value on current touch surface 151 is obtained by the touch panel 15.
Step S205, the execution module 105 when determine have touch operation on the touch-surface 151 when, execute corresponding
Touch operation.
The present invention covers the state of the water quality of touch-surface 151 by detecting, and obtains institute according to the state of the water quality
State the current background value of touch panel, even and if then the touch device 1 under water, also can accurately judge touch panel 15
Whether there is touch operation on touch-surface 151.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be understood by those of ordinary skill in the art that, it can modify to technical scheme of the present invention
Or equivalent replacement, without departing from the spirit of the technical scheme of the invention and range.
