The Chinese patent with the application number of CN201610520599.0 discloses a method, a device and a terminal for detecting immersion. The patent is mainly used for accurately judging the terminal soaking degree and preserving the terminal soaking evidence by recording the terminal soaking water pressure and the terminal soaking time after the terminal is soaked. The technical scheme is only to process the situation after soaking, and the electronic equipment still cannot automatically identify whether soaking occurs.
The Chinese patent with the application number of CN201510277858.7 discloses a wearable intelligent card for monitoring the state of a swimmer, and the wearable intelligent card can effectively sense the behavior and the state of the swimmer through fusion, analysis and processing of multi-sensor data, and can send out early warning information when the swimmer is likely to drown, remind guardianship personnel and other swimmers to search for drowns in time, so that tragedy occurrence is avoided. The patent mainly judges whether the terminal is immersed or not through an electric pulse mode, on one hand, the monitoring effect is to be confirmed, and on the other hand, the cost is increased due to the fact that multiple sensors are needed.
In summary, a technical solution is needed that can automatically identify whether the electronic device is immersed in water, and has low cost and good effect.
The electronic device adopts a capacitive touch screen, according to the characteristics of the touch screen during capacitance, when the surface of the touch screen is immersed in water, the capacitance of a touch circuit electrode of the touch screen is changed under the influence of water, and the capacitance change is different from the case that the touch screen is completely contacted with air, and is also different from the contact of the touch screen with fingers of a person. The technical scheme is applied to the electronic equipment, can automatically identify whether the electronic equipment is immersed or not, and is low in cost and good in effect.
Specific implementation modes of the technical scheme of the application are described in detail below. It should be noted that the electronic device described in the present application may be any device having a capacitive touch screen. In one implementation, the electronic device described herein may be (but is not limited to): mobile terminals such as cell phones, tablet computers, notebook computers, palm top computers, personal digital assistants (Personal Digital Assistant, PDA), portable media players (Portable Media Player, PMP), navigation devices, wearable devices, smart bracelets, pedometers, and the like.
Example 1
As shown in fig. 1, the method of identifying a flooding condition may include:
step 101, collecting coupling capacitance data of an ITO line electrode or an ITO line electrode to the ground on a touch screen;
step 102, determining whether the touch screen is immersed or not by using the coupling capacitance data;
and 103, when the touch screen is determined to be immersed, emitting an immersed prompt signal.
According to the embodiment, whether the electronic equipment is in the immersed state is detected by utilizing the characteristic of the water touch abnormality on the capacitive touch screen, whether the electronic equipment is in the immersed state can be automatically identified without a complex structure or circuit mechanism, the cost is low, and the effect is better.
In this embodiment, the determining whether the touch screen is immersed by using the coupling capacitance data may include: comparing one or two of pre-stored coupling capacitance reference data and coupling capacitance soaking reference data with currently acquired coupling capacitance data, and determining whether the touch screen is soaked or not according to a comparison result; the coupling capacitance reference data are coupling capacitance data of an ITO line electrode or an ITO line electrode to the ground when the touch screen is in contact with air. Coupling capacitance immersion reference data represents coupling capacitance data of an ITO line electrode or an ITO line electrode to ground when the touch screen is in contact with water (or other liquid with a water insulation coefficient).
In practical application, for a capacitive touch screen, the direction of signal change generated by human body and water on the touch screen is opposite, the human body can reduce the coupling capacitance of the ITO electrodes of the touch screen, and the water can increase the coupling capacitance between the ITO electrodes. Based on this characteristic, in one implementation, the determining whether the touch screen is immersed using the coupling capacitance data may include one or more of: 1) Comparing the coupling capacitance data with pre-stored coupling capacitance reference data, and determining that the corresponding position of the touch screen is immersed when the coupling capacitance data is larger than the coupling capacitance reference data; 2) Comparing the coupling capacitance data with pre-stored coupling capacitance soaking reference data, and determining that the corresponding position of the touch screen is soaked when the coupling capacitance data is equivalent to the coupling capacitance soaking reference data; 3) And comparing the coupling capacitance data with pre-stored coupling capacitance soaking reference data and coupling capacitance reference data respectively, and determining that the corresponding position of the touch screen is soaked when the coupling capacitance data is larger than the coupling capacitance reference data and is equivalent to the coupling capacitance soaking reference data.
In this embodiment, the coupling capacitance data between the ITO line electrodes may include one or both of the following: a capacitance value of a coupling capacitance between the ITO line electrode or the ITO line electrode to the ground; the current value of the coupling capacitance between the ITO line electrode or the ITO line electrode to the ground. Accordingly, the coupling capacitance reference data may include one or both of: the capacitance value of the coupling capacitance between the ITO line electrode or the ITO line electrode and the ground when the corresponding position of the touch screen is contacted with air; and when the corresponding position of the touch screen is in contact with air, the ITO line electrode or the ITO line electrode is opposite to the current value of the coupling capacitor of the ground. Correspondingly, the coupling capacitance immersion reference data may include one or both of the following: when the corresponding position of the touch screen is contacted with water, the capacitance value or the capacitance value range of the coupling capacitance between the ITO line electrode or the ITO line electrode and the ground is equal to that of the coupling capacitance; and when the corresponding position of the touch screen is contacted with water, the ITO line electrode or the coupling capacitance of the ITO line electrode to the ground is a current value or a current value range.
The process of determining whether the touch screen is immersed or not using the coupling capacitance data in the present embodiment will be described in detail with a specific example.
Taking a capacitive touch screen as an example, the capacitive touch screen may include: touch screen apron ITO and touch control module, this touch control module can be the touch-control chip of capacitive touch screen.
As shown in fig. 2, when the touch screen surface is free of conductors and is in direct contact with air, the inter-electrode coupling capacitance data (or electrode-to-ground capacitance) of the conductive glass (ITO) line is C1 (may be a capacitance value or a current value), and this data may be pre-stored in the electronic device as coupling capacitance reference data for comparison with subsequently acquired touch screen capacitance data. In one implementation, the coupling capacitance reference data may be a specific value or an interval value, and the value or interval value of the coupling capacitance reference data may be an empirical value obtained through analysis and statistics after a large number of acquisitions.
As shown in fig. 3, when a human body (such as a finger) touches the surface of the touch screen, the data of the inter-electrode coupling capacitance (or electrode-to-ground capacitance) of the ITO line is C2 (which may be a capacitance value or a current value), and this data is the coupling capacitance of the human body and the touch screen electrode superimposed.
As shown in fig. 4, when the surface of the touch screen is water (or other liquid with an insulation coefficient equivalent to that of water), the inter-electrode capacitance (or electrode-to-ground capacitance) data of the ITO line is C3 (which may be a capacitance value or a current value), and this data is a coupling capacitance obtained by superimposing water and the electrode of the touch screen, and this data may be pre-stored in the electronic device as a coupling capacitance immersion reference data for subsequent comparison. In one implementation, the reference data of the coupling capacitor flooding may be a specific value or an interval value, and the value or interval value of the reference data of the coupling capacitor flooding may be an empirical value obtained through analysis and statistics after a large number of acquisitions.
The coupling capacitance values of the coordinate points of the touch screen in the air contact state are shown in fig. 5, the coupling capacitance values of the coordinate points when the touch screen is pressed by a finger are shown in fig. 6, and the coupling capacitance values of the coordinate points after the surface of the touch screen is covered by water are shown in fig. 7.
As can be seen from fig. 5, 6 and 7, the following table 1 shows the results for some coordinate points, and thus the values or interval values of the coupling capacitance reference data and the coupling capacitance immersion reference data at the corresponding positions of the corresponding coordinate points can be known.
TABLE 1
Here, the coupling capacitance data is a value after AD conversion. From the experimental data shown in fig. 5, 6 and 7, the value of the coupling capacitance of the human body touch is reduced by about 400-1500, and the value of the coupling capacitance is increased by 30-200 in the immersed state, so that the value or interval value of the coupling capacitance reference data and the value or interval value of the coupling capacitance immersed reference data can be determined. In practical applications, the coupling capacitance data at different locations of the touch screen is not exactly the same. In one implementation, different coupling capacitance reference data and different coupling capacitance submersion reference data may be configured for different locations. That is, when the coupling capacitance reference data and/or the coupling capacitance immersion reference data are pre-stored, the values or section values of the coupling capacitance reference data and/or the coupling capacitance immersion reference data may be stored in correspondence with the coordinate information of the touch screen. Therefore, when the coupling capacitance data is used for determining whether the touch screen is immersed, the collected coupling capacitance data can be compared with the coupling capacitance reference data and/or the coupling capacitance immersed reference data under the same coordinate information, so that whether the corresponding position of the touch screen is immersed or not can be accurately confirmed, and the touch screen can be regarded as immersed when the appointed position of the touch screen is immersed.
As shown in fig. 8, an exemplary implementation process for determining whether a corresponding location on a touch screen is immersed may include:
step 500, when the surface of the touch screen is free of a conductor and is in direct contact with air, acquiring coupling capacitance data between electrodes or between electrodes of an ITO line at certain point positions or full-screen point positions on the touch screen through a touch control module of the touch screen, and analyzing and counting the coupling capacitance data to obtain coupling capacitance reference data C1 and pre-storing the coupling capacitance reference data C1;
step 501, collecting current coupling capacitance data C of ITO line electrodes or ITO line electrodes to the ground at certain point positions or full-screen point positions on a touch screen through a touch control module of the touch screen;
step 502, sending the coupling capacitance data C to a CPU of the electronic device, and at the same time, the CPU reads pre-stored coupling capacitance reference data C1;
step 503, the cpu compares the coupling capacitance data C with the coupling capacitance reference data C1, and determines whether the coupling capacitance data C is greater than the coupling capacitance reference data C1;
step 504, if the coupling capacitance data C is equivalent to the coupling capacitance reference data C1 (identical or within a preset error range), the touch screen is considered to be currently in direct contact with air, the electronic device has no operation or abnormality, and the step 501 is returned to continue monitoring;
Step 505, if the coupling capacitance data C is smaller than the coupling capacitance reference data C1, the touch screen is considered to be directly touched with the human body at present, and the current flow is ended;
in step 506, if the coupling capacitance data C is greater than the coupling capacitance reference data C1, it is considered that there is water at some point positions or all full-screen point positions of the touch screen at present, that is, the touch screen is in a immersed state, and the technology is currently in flow.
It should be noted that fig. 8 is merely an exemplary implementation. The process of determining whether the touch screen is immersed or not by using the coupling capacitance data in this embodiment may also be implemented in other manners.
In this embodiment, there are various implementations for sending out the flooding alert signal. In one implementation, the sending out the flooding cue signal may include: and (5) performing bright and dark flashing. For example, the touch screen or the display screen can be turned on or off to flash, the front flash lamp can be turned on or off to flash, and the rear flash lamp can be turned on or off to flash. After the electronic equipment is identified to be in a water soaking state, the specific position of the electronic equipment in water can be effectively identified by the flicker of the display screen or the flash lamp, so that the electronic equipment is convenient for a user to salvage.
In order to facilitate after-sales service for manufacturers of electronic devices, the embodiment can also automatically record whether the electronic devices have over-immersed conditions. That is, after determining whether the touch screen is immersed in water using the coupling capacitance data, it may further include: and when the touch screen is determined to be immersed in water, resetting the immersed flag bit, so that the immersed flag bit indicates that the touch screen is immersed in water. The flooding flag bit can be used as a judging basis for judging whether the electronic equipment has the flooding condition. In one implementation, a flooding flag bit may be pre-configured at a designated location in a memory of an electronic device, and after determining that the touch screen is flooded, the flooding flag is incremented by 1, indicating that the electronic device has been flooded once. If the soaking condition occurs, the soaking zone bit can be continuously added with 1, so that the electronic equipment can be judged to be soaked for several times according to the numerical value of the soaking zone bit, and manufacturers can know the service condition of the electronic equipment conveniently according to the numerical value of the soaking zone bit, so that corresponding after-sales service can be provided.
In practical applications, the coupling capacitance data between one or a group of ITO line electrodes corresponds to a specific location on the touch screen. Based on the above, the water immersion recognition of multiple modes such as multiple points, partial screens, full screens and the like can be performed according to the preset area or preset position of the actual requirement. In one implementation of this embodiment, the method may include: collecting coupling capacitance data of a set area or a set position on the touch screen; determining whether the set area or the set position is immersed or not by using the coupling capacitance data of the set area or the set position; and when the set area or the set position is determined to be immersed, an immersion prompt signal is sent out. Here, the set position and the set area may be preconfigured in the electronic apparatus by the coordinate information so as to be detected for the set position or the set area in the flooding recognition process. Here, the setting area may be a certain area of the touch screen, a full-screen area of the touch screen, and the setting position may be plural or one. In one implementation, to prevent false triggers, an area or locations that can represent the entire touch screen may be selected. For example, 9 points as shown in fig. 9 may be selected, or the full touch screen AA area detection as shown in fig. 10 may be selected. In one implementation, determining whether the set area or set location is immersed in water using coupling capacitance data of the set area or set location may include: comparing one or two of pre-stored coupling capacitance reference data and coupling capacitance soaking reference data of the set area or the set position with coupling capacitance data of the set area or the set position which are collected currently, and determining whether the touch screen is soaked or not according to a comparison result; the coupling capacitance reference data are coupling capacitance data when the touch screen is in contact with air. Here, the specific process may be referred to the above related description, and will not be repeated.
In order to make the flooding identification more accurate or adapt to some specific application scenarios, the flooding identification can be realized by combining other conditions. In this embodiment, before collecting the coupling capacitance data of the ITO line electrode or the ITO line electrode to the ground on the touch screen or before determining whether the touch screen is immersed in water by using the coupling capacitance data, the method may further include: detecting whether the electronic device satisfies one or more of the following conditions: is in a motion state; the external environment satisfies the set condition. Here, the setting condition satisfied by the external environment may include one or more of the following: the light of the external environment is weakened by strong or lower than a set threshold value; the pressure of the external environment to the touch screen is changed from weak to strong or the pressure is within a set range. Here, the set range of the pressure may be an empirical value obtained by performing statistical analysis on pressure data of the touch screen in deep water. The set threshold value of the light ray can be an empirical value obtained by carrying out statistical analysis on the light intensity data of the electronic equipment in deep water. The motion state machine related data can be collected through an acceleration sensor, a gyroscope and the like, and the external environment related pressure data, light data and the like can be collected through an infrared sensor or other similar sensors.
In this embodiment, when it is detected that the electronic device meets one or more conditions, recognition of a flooding state is started, that is, coupling capacitance data of an ITO line electrode or an ITO line electrode to ground on a touch screen is collected, or whether the touch screen is flooded is determined by using the coupling capacitance data.
For example, the electronic device suddenly slides down and falls into the water in a plurality of scenes, and for the scenes, the detection of the motion state of the electronic device can be increased, and the coupling capacitance data is used for determining whether the touch screen is immersed in the water or not after the electronic device is in the motion state. For another example, when the electronic device falls into deep water, whether the electronic device is immersed is determined by detecting whether the current external environment meets the set condition and determining whether the touch screen is immersed by using the coupling capacitance data.
In this embodiment, the immersion protection function of the electronic device may also be triggered and started after determining that the touch screen is immersed. In one implementation manner, after determining whether the touch screen is immersed in water by using the coupling capacitance data, the method may further include: when the touch screen is determined to be immersed, triggering and starting an immersion protection function; the starting of the water immersion protection function includes one or more of the following: 1) Sending a message indicating that the current electronic equipment is immersed to other set electronic equipment or a set third party server; for example, after the user falls into deep water together with the electronic equipment, the electronic equipment can automatically send out emergency information through the function; for another example, when the user fails to perceive due to the electronic device sliding down deep water, the electronic device can automatically send a reminding message to other electronic devices set by the user through the function so as to remind the user to take measures in time; 2) Opening the waterproof structure so that the waterproof structure isolates one or more devices (e.g., MIC, earpiece, speaker, earpiece aperture, etc.) in the electronic device from water in an open state; 3) Shooting is started. In addition, the water immersion protection function may include others, which are not limited herein.

Example 1
The immersion state recognition process of the portable mobile terminal is described in detail in this example.
As shown in fig. 15, the terminal's flooding state recognition process may include the steps of:
step 1201: the acceleration sensor detects the terminal acceleration;
the acceleration sensor configured by the terminal monitors the acceleration state of the terminal itself, namely, the change condition of the speed.
Step 1202: judging whether the acceleration changes, if so, indicating that the terminal is in a motion state, and if not, indicating that the terminal is in a static state; if there is a change in acceleration, the process proceeds to step 1203, and if there is no change in acceleration, the process returns to step 1201.
When the terminal is in use or carried by a user, the terminal is often in position movement, the position movement brings speed change, and the acceleration sensor can detect the speed change and inform the CPU of the information.
Considering a scenario where the terminal inadvertently slips off the user's hand or pocket into the water, the terminal itself may change in speed during this process, and the acceleration sensor may be able to detect the change in speed.
If the acceleration is unchanged, the process returns to the acceleration sensor monitoring state at step 1201.
Step 1203: detecting a touch function of the display screen assembly;
when the acceleration sensor detects the change of the speed of the terminal and notifies the CPU of information, the CPU notifies the touch control module to detect the touch control function of the touch screen, and the detection can be performed under the condition that the display screen is on or off.
Judgment 1204: judging whether the touch function of the touch screen is normal, namely whether the touch screen is immersed, if not, continuing to step 1205, and if so, returning to step 1201.
The coupling capacitance reference data and/or the coupling capacitance soaking reference data of a set area or a set position (9 points or other multiple points or full AA area) on the touch screen are pre-stored in the terminal.
The touch control module sends the currently detected coupling capacitance data of the ITO line electrode or the electrode to the ground at a set area or a set position on the touch screen to the CPU, and the CPU compares the currently detected coupling capacitance data with pre-stored coupling capacitance reference data and/or coupling capacitance soaking reference data to determine whether the function of the touch screen is abnormal, namely whether the touch screen is soaked or not.
Step 1205: the CPU starts a water immersion warning function;
step 1206: the CPU starts the flash lamp through the flash lamp driving module, and controls the flash lamp to be turned on and off and flash according to a preset mode (namely the flash frequency in a preset soaking mode), so as to give a dominant prompt to a user.
Step 1207: the CPU lights the display screen through the display driving module, and controls the display screen to flash according to a preset mode (namely the flashing frequency in a preset soaking mode), so as to give a dominant prompt to a user.
Step 1208: the CPU adds 1 to the soaking flag bit written in the appointed position of the memory, so as to be used as the basis for after-sales processing.
It should be noted that, in this example, one of the steps 1206 and 1207 may be selected, and the execution sequence may be sequential or simultaneous, which is not limited.
Example 2
The immersion state recognition process of the portable mobile terminal is described in detail in this example.
As shown in fig. 16, the terminal's flooding state recognition process may include the steps of:
step 1301: the touch control module monitors the coupling capacitance data of the display screen assembly and sends the coupling capacitance data to the CPU;
judgment 1302: the CPU judges whether the touch function of the touch screen is normal or not, namely whether the touch function is immersed, if not, the step 1303 is continued, and if so, the step 1301 is returned to;
The coupling capacitance reference data and/or the coupling capacitance soaking reference data of a set area or a set position (9 points or other multiple points or full AA area) on the touch screen are pre-stored in the terminal.
The touch control module sends the currently detected coupling capacitance data of the ITO line electrode or the electrode to the ground at a set area or a set position on the touch screen to the CPU, and the CPU compares the currently detected coupling capacitance data with pre-stored coupling capacitance reference data and/or coupling capacitance soaking reference data to determine whether the function of the touch screen is abnormal, namely whether the touch screen is soaked or not.
Step 1303: the CPU starts a water immersion warning function;
step 1304: the CPU starts the flash lamp through the flash lamp driving module, and controls the flash lamp to be turned on and off and flash according to a preset mode (namely the flash frequency in a preset soaking mode), so as to give a dominant prompt to a user.
Step 1305: the CPU lights the display screen through the display driving module, and controls the display screen to flash according to a preset mode (namely the flashing frequency in a preset soaking mode), so as to give a dominant prompt to a user.
Step 1306: the CPU adds 1 to the soaking flag bit written in the appointed position of the memory, so as to be used as the basis for after-sales processing.
It should be noted that, in this example, step 1304 and step 1305 may be performed in either order, or may be performed simultaneously, which is not limited.
Example 3
In this example, a portable mobile terminal is taken as an example, and a detailed description is given of a closing mode of the water immersion warning function.
In this example, the water immersion warning function may be turned off in a plurality of ways.
In one implementation, as shown in fig. 17, the turning-off procedure of the water immersion warning function may include:
step 1401: the user manually cleans water stains on the touch screen of the terminal, and eliminates factors influencing the touch function, so that the touch screen function is recovered to be normal;
step 1402: the user performs touch operation on the touch screen in a clicking, double-clicking or long-pressing mode and the like;
step 1403: and under the triggering of the touch operation of a user, the current water immersion warning function is closed.
In another implementation, the closing process of the water immersion warning function may include: the terminal enters a shutdown state due to the fact that the battery is exhausted or a circuit short circuit occurs due to water immersion; because the terminal is shut down, the terminal is shut down when the water immersion warning function.
In yet another implementation, the closing process of the water immersion warning function may include: the user manually executes shutdown operation in modes of key press, interface operation and the like, and the terminal enters a shutdown state; because the terminal is shut down, the terminal is shut down when the water immersion warning function.
