Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, those skilled in the art's every other implementation obtained without creative efforts
Example, shall fall in the protection scope of this application.
The present embodiment will be described from the angle of mobile terminal water inlet detecting device, the mobile terminal water inlet detecting device
It can integrate in the terminal, mobile terminal may include mobile phone, tablet computer etc..
As shown in Figure 1, Fig. 1 is the structural schematic diagram of mobile terminal water inlet detecting device provided by the embodiments of the present application, it should
Mobile terminal water inlet detecting device may include: into water detector 10, encoder 20 and main controller 30, in which:
(1) water inlet detector 10
Detector 10 of intaking exports water inlet and detects signal for detecting to mobile terminal.
In the present embodiment, on mobile terminals, after mobile terminal water inlet, water inlet detector exports the setting of water inlet detector
Signal can change, therefore obtain the water inlet detection signal of water inlet detector output to carry out subsequent detection.
Preferably, as shown in Fig. 2, the water inlet detector 10 includes at least one water inlet detection unit 11；It is described at least
One water inlet detection unit 11 is set to the different zones of the mobile terminal.
In a specific embodiment, water inlet detector include 8 water inlet detection units, respectively 11-1,11-2,
11-3 ..., 11-8, as shown in figure 3,8 water inlet detection unit distributions are in the region of the easy water inlet of mobile terminal, thus right
Mobile terminal carries out comprehensive water inlet detection.
Further, the water inlet detection signal includes the signal that all water inlet detection units 11 export；
Each water inlet detection unit 11 exports high level or low level for detecting to its region.
It should be noted that water inlet detection signal is level signal.Each water inlet detection unit is according to its region
Flooded condition exports high level or low level, and the low and high level of all water inlet detection unit outputs constitutes the water inlet detection letter
Number.
Further, each water inlet detection unit includes two test points；
Each water inlet detection unit is specifically used for the on off operating mode by described two test points to detect its place
Region；In the connection of described two test points, low level is exported, when described two test points disconnect, exports high level.

In encoder, encoder is encoded according to the low and high level that all input pins input.The level of each input pin input is different,
Then the coding result of encoder output is different.
Further, the encoder 20 is specifically used for that priority is arranged to all input pin INPUT；In all input pins
It is the first encoded radio by water inlet detection Signal coding, at least one input pin INPUT when the equal input high level of INPUT
When input low level, the low level input pin of highest priority is obtained, is and acquisition by water inlet detection Signal coding
Corresponding second encoded radio of input pin INPUT；First encoded radio or second encoded radio is defeated as coding result
Out.
It should be noted that encoder is numbered in sequence to all input pins, it is preferential to number bigger input pin
Grade is higher.In turn, the level signal that encoder inputs all input pins detects, if the level letter of all input pins input
Number it is high level, then all level signals is encoded to the first encoded radio；If the level signal for having input pin to input is low electricity
It is flat, then the input pin of highest priority is obtained from the input pin of input low level, and all level signals are encoded to second
Encoded radio, second encoded radio be numerical value associated with the input pin of acquisition, such as acquisition input pin number.It encodes

Encoder by input pin 1,2,3 ..., 9 input low and high levels, pass through output pin A, B, C, D exports coding knot
Fruit.Wherein, the highest priority of the input pin 9 of encoder, the priority of input pin 1 is minimum, and the input pin of encoder and defeated
Foot is low effective out, then the coding table of comparisons of encoder is as shown in table 1." H " in table indicates that high level, " L " indicate low electricity
Flat, " X " indicates high level, low level.
Table 1
As it can be seen from table 1 when input pin 1,2,3 ..., some input pin is low level in 9, remaining input pin is height
When level, the coding of output pin output is the number of low level input pin；When input pin 1,2,3 ..., have in 9 simultaneously it is more
It is minimum next according to current low level defeated by 9 highest priority of input pin, 1 priority of input pin when a input pin is low level
Enter the input pin of highest priority in foot to encode；When input pin 1,2,3 ..., 9 be high level when, output pin output
It is encoded to 0.

When device, the timer at predetermined time intervals (such as 10 seconds) obtain output pin A, B, C, D output low and high level, and according to D, C,
B, the sequence of A carries out binary coding to the level of input, i.e. high level is encoded to 0, and low level is encoded to 1, so by two into
Code conversion processed is decimal coded.After obtaining decimal coded, judge whether mobile terminal intakes according to coding, if compiling
Code is 0, then determines that mobile terminal is not intake, if being encoded to K (being not 0), determines that mobile terminal is intake, and further determine defeated
Enter the region water inlet where water inlet detection unit 11-K corresponding to foot K, and corresponding to input pin of the priority lower than input pin K
Water inlet detection unit where region may intake, i.e. water inlet detection unit 11-1,11-2 ..., the area where 11-K-1
Domain may intake.For example, after determining the water inlet of the water inlet region detection unit 11-3, detection unit 11-1,11-2 of intaking
It may water inlet.Master controller sends water inlet to user and reminds after judging the flooded condition of mobile terminal.
It can be seen from the above, mobile terminal water inlet detecting device provided by the present application, it can be by water inlet detector to movement
Terminal is detected, and output water inlet detection signal, it is coding structure that water inlet, which is detected Signal coding, by encoder, passes through master control
