Specifically referring to fig. 1, fig. 1 is a schematic diagram of a basic flow of the water-detecting method of this embodiment.
As shown in fig. 1, a method for water detection includes the following steps:
s1100, acquiring an electric signal flowing through a first terminal in an environment through the exposed first terminal;
the terminal is provided with a first terminal and a second terminal which are exposed, the first terminal is used for collecting electric signals in the environment, and the second terminal is used for continuously sending electric signals with specific waveforms. For example, data transmission is carried out by conducting the D + end and the D-end of the USB thimble, and when the USB thimble normally works, one exposed terminal continuously sends an electric signal, and the other terminal continuously collects the electric signal in the environment. Taking the USB interface as an example, the D + end of the USB thimble continuously transmits an electrical signal with a specified waveform as a basis for verification, and when the D + end and the D-end are connected, the data information transmitted by the D + end can be received by the D-end. By monitoring the D-terminal, the electric signals flowing through the D-terminal in the environment are collected in real time.
S1200, analyzing waveform information of the electric signal and comparing and verifying the waveform information with a preset verification waveform, wherein the waveform of the electric signal sent by a second terminal correspondingly arranged to the first terminal is consistent with the verification waveform;
After the first terminal collects the electric signals in the environment, waveform information of the electric signals is obtained through analysis, and the waveform information and the check waveform are compared and verified. The exposed second terminal continuously sends the electric signal with the waveform consistent with the check waveform, so that the first terminal can collect the electric signal with the waveform consistent with the check waveform when the water is conducted. Taking the USB interface as an example, the D + terminal of the USB interface continuously transmits the electrical signal with the waveform consistent with the verification waveform. And comparing the electric signal waveform information acquired by the first terminal with the check waveform to obtain a comparison result of the electric signal waveform information and the check waveform. When the two are completely consistent, the first terminal and the second terminal are determined to be completely conducted, and when the two are not completely consistent, a distinguishing point between the two is analyzed.
Specifically, since the medium that is conducted in the environment may attenuate the transmitted electrical signal, when the first terminal and the second terminal are conducted, the waveform information and the verification waveform are not necessarily completely consistent, and the comparison result may be affected differently according to the degree of the influence of the conducting medium on the signal transmission. For example, there may be a difference in waveform frequency, but the present invention is not limited thereto, and the comparison result may be set according to actual situations, for example, the frequency of the waveform information is reduced by 5% compared with the check waveform.
S1300, when the waveform information and the check waveform are verified successfully, confirming that a preset water meeting condition is achieved, wherein the verification success means that the waveform information and the check waveform are consistent or the difference between the waveform information and the check waveform is within a preset variation range;
and judging whether the water-meeting condition is achieved or not according to the comparison verification result of the waveform information and the check waveform, wherein the verification is successful, namely the two are consistent or the difference of the two is within a certain range.
Specifically, when the terminal is completely immersed in water, the transmitting end and the receiving end of the data transmission interface use water as a medium and are in a conducting state, and at this time, waveform information acquired by the receiving end and a check waveform transmitted by the transmitting end should be consistent, but because the conductivity of the medium is different, when the conductivity of the medium is poor, a transmitted signal may have a certain attenuation, so that the waveform information and the check waveform are not completely consistent, and the difference between the two is still within a certain range.
When the terminal accidentally contacts water in the daily use process (for example, the terminal is splashed with water or a human body sweats), the conduction effect of the two terminals is different from that of the terminal when the terminal is completely immersed, for example, the terminal is possibly in an incomplete conduction state when being splashed with water, data information is interrupted in the transmission process, and an electric signal acquired by a receiving end is incomplete, so that the result obtained when comparing and verifying the waveform information obtained by analysis and the verification waveform is possibly large in difference, and at the moment, the terminal can be judged to be in a state without danger and does not need to take measures.
When the water-meeting condition is met, it is determined that the equipment is in the water-meeting state, and certain remedial measures need to be taken, for example, prompt information is sent to the associated terminal to remind relevant personnel to respond.
As shown in fig. 2, step S1300 is followed by the following steps:
s1310, judging distinguishing characteristics between the waveform information and the check waveform; and comparing the acquired waveform information with the check waveform, and judging the distinguishing characteristic range of the distinguishing point between the acquired waveform information and the check waveform. According to the difference of the transmitted data information, a specific distinguishing characteristic can be set according to the actual situation, for example, when the transmitted data information is an electrical signal, the distinguishing characteristic can be frequency attenuation of the waveform information compared with the verification waveform, and the like, but is not limited thereto. The distinguishing characteristic can set different gradient ranges, such as frequency attenuation of 5% -10% and 10% -15%, according to different practical application scenarios.
S1320, searching a scene type having a mapping relation with the distinguishing characteristics in a preset scene database;
the scene database stores data corresponding to different scene types, such as water immersion, splash, sweat or the like, and is used for distinguishing different water-encountering scenes. When a scene database is constructed, firstly, a large amount of experimental data is acquired as test data of a corresponding scene, for example, for a water immersion scene, a verification test is performed on equipment in a water immersion state, the acquired data is test data, a difference point between a waveform of an electric signal received by a first terminal and a preset test waveform is judged, and a range of the difference point in the scene is acquired through a plurality of groups of experimental data and is used as a difference characteristic corresponding to a scene type. After the corresponding distinguishing features of each scene are acquired, the distinguishing features and the scene types are stored in a scene database in a mapping relation mode. The distinguishing of the scene types can be adjusted according to the actual application requirements, for example, when the scenes need to be classified more finely, the scene of 'soaking' can be refined into seawater, river water, tap water and the like.
And after the distinguishing features are judged, searching the scene type which has a mapping relation with the distinguishing features in a scene database.
S1330, defining the scene type with the mapping relation as scene information;
and determining the searched scene type having a mapping relation with the distinguishing features as the current scene information of the terminal.
Different water-meeting scenes can be effectively distinguished by distinguishing the mode of determining the scene information of the terminal through the characteristic, so that a basis is provided for subsequent measures, and the condition that the daily water-meeting condition mishaps to be urgent danger caused by adopting the same coping mode aiming at all the water-meeting conditions is avoided.
As shown in fig. 3, the method further comprises the following steps:
s2110, obtaining scene test information of a target scene type, wherein the scene test information comprises test waveform information of a test electric signal acquired by the first terminal when the scene is in a target scene;
when a scene database is constructed, scene testing of verification data is carried out on the terminal under different scenes, the scene testing is that under the type of a target scene, electric signals with waveforms consistent with the testing waveforms are sent through the second terminal, environment electric signals collected by the first terminal are collected and analyzed to obtain testing waveform information of the testing electric signals, and the testing waveform information obtained through the testing is used as scene testing data. According to the classification type of the scene, different scenes are tested for multiple times, such as a soaking state, a splashing state, sweat conduction and the like.
The method includes the steps that multiple times (such as 1000 times) of tests are conducted on a scene under a target scene state, so that multiple groups (such as 1000 groups) of test data are obtained, for example, a terminal is immersed into water in a soaking state, test electric signals collected by a first terminal are obtained, and corresponding test waveform information is obtained through analysis. In order to enable the scene test data to be more objective and real, when the same scene is tested, the scene details can be changed according to the actual situation, for example, for the immersion state, the terminal can be immersed in river water, seawater or tap water respectively for testing; for the splash condition test, the terminal can be splashed from different angles and different water amounts of the terminal respectively, and the like. And taking the test waveform information obtained by the test as scene test data of the target scene type.
S2120, comparing the waveform information of the test electrical signal with a preset test waveform to obtain a signal change characteristic, wherein the waveform of the electrical signal sent by the second terminal is consistent with the test waveform;
analyzing the distinguishing features of each set of acquired scene test data and the test waveform, where possible scene test data distinguishing points include, but are not limited to, frequencies, and the like, and the comparison result may be set according to actual situations, for example, the frequency of the waveform information of the test electrical signal is reduced by 5% compared with the test waveform, but is not limited to, this.
After acquiring multiple sets of test data distinguishing features of the same scene, counting the range of all the test data distinguishing features, and taking the variation range of the test data as the variation feature of the signal, such as frequency attenuation of 5-10%.
And respectively testing and processing by using the method to obtain the signal change characteristics of each preset scene classification.
S2130, determining distinguishing characteristics corresponding to the target scene type according to the signal change characteristics, and inputting the distinguishing characteristics into the scene database;
after the signal change characteristics are obtained, the signal change characteristics are stored in a scene database as distinguishing characteristics corresponding to the target scene type, and the distinguishing characteristics of each preset scene type are respectively obtained and stored through the method, so that the scene database is constructed.
The corresponding relation between the scene type and the distinguishing characteristic range is obtained through a scene test mode, so that a scene database is constructed, a reference basis for data analysis is provided for the process of water-encountering detection, the scene can be distinguished more accurately during the water-encountering detection, and the accuracy of the water-encountering detection is improved.
As shown in fig. 4, step S1330 is followed by the following steps:
S1340, acquiring position information, wherein the position information is positioning data when the water-meeting condition is achieved;
and after the scene information of the terminal is judged, acquiring real-time positioning data of the terminal as position information. Specifically, the positioning data of the terminal is determined through hardware information of a module (such as a GPS module or a Wi-Fi module) having a positioning function in the terminal, and the positioning data is associated with preset map data, so that information such as a position where the terminal is located and a position name is determined in a map.
S1350, generating prompt information according to the position information and the scene information; after the position information is acquired, prompt information is generated according to the position information and the scene information, and the prompt information includes, but is not limited to, a terminal position, a scene type, a prompt, and the like. In some embodiments, different prompt languages are set for different scene types, and a corresponding prompt language is selected according to the scene type of the terminal to generate the prompt information, for example, for a water immersion scene, the corresponding prompt language may be "a child may have a drowning danger and please go to rescue as soon as possible", and the setting of the content of the prompt language may be adjusted according to actual application requirements, which is not limited herein.
S1360, sending the prompt information to associated equipment, and triggering an alarm instruction of the associated equipment;
the terminal can be associated with one or more other devices when being set, for example, when the terminal is a child watch, the terminal can be associated with electronic devices such as a parent's mobile phone and a computer through a network, after the prompt information is obtained, the prompt information is sent to the associated devices, and the prompt information further comprises a warning trigger instruction of the associated devices so as to remind users of the associated devices of paying attention to the prompt information in time. For example, the terminal a sends a prompt message to the parent's mobile phone, the parent's mobile phone triggers a warning instruction (such as a ring or a vibration, but not limited thereto) after receiving the prompt message, and displays a prompt message "a is in a submerged state at the position B, a child may be in danger of drowning, and please go to help as soon as possible", the prompt message may be associated with a map application in the mobile phone, and a specific position where the a is located may be displayed in the map application when the position B is clicked, so that the parent is guided to go to the current location of the parent a more accurately and quickly.
The terminal is judged to acquire position data after meeting water state to generate prompt information and send the prompt information to the associated equipment to remind relevant personnel, the relevant personnel can be informed to take remedial measures in time when the terminal meets water and is possibly dangerous, the relevant personnel are guided to go to a target place through positioning data, and drowning risk of a terminal holder is effectively reduced.
As shown in fig. 5, the following steps are further included after step S1300:
s1410, acquiring water-encountering time information, wherein the water-encountering time information is the time passing after the water-encountering condition is achieved;
when the water-meeting condition is achieved, timing is started, whether the water-meeting condition is achieved is judged once again at regular time intervals (such as 5 seconds), and when the water-meeting condition is judged again, the time elapsed after timing is determined to be the water-meeting time.
S1420, comparing the water encountering time information with a preset first time threshold;
a first time threshold (e.g., 30 seconds) is preset in the system to distinguish whether it is accidentally water-wet or truly submersed in water. Specifically, the acquired water contact time is compared with a first time threshold value, and whether the water contact time is greater than a preset first time threshold value is judged. The value of the first time threshold can be adjusted according to actual use requirements, for example, when the water-meeting condition of the terminal needs to be judged more quickly and an alarm is given, the value of the first time threshold can be reduced appropriately; when the water-meeting condition of the terminal needs to be judged more accurately so as to reduce misjudgment caused by accidental water meeting, the value of the first time threshold value can be properly increased.
S1430, when the water encountering time information is greater than the first time threshold, triggering a preset water encountering prompt instruction;
when the water-meeting time is judged to be larger than the first time threshold value, the time that the terminal is in the water-meeting state is long enough, the terminal can be really immersed in water at the moment, the holder of the terminal can be in danger of drowning, and a preset water-meeting prompt instruction is triggered. The water-encounter prompt instruction may be to send a specified prompt message to the associated device to guide the associated person to go for help.
Through setting for meeting water time, can effectively distinguish and meet water and really appear dangerous scene by accident, reduce the erroneous judgement rate to meeting the water condition.
As shown in fig. 6, the following steps are further included after step S1430:
s1440, acquiring water leaving time information, wherein the water leaving time information is the time elapsed after the verification fails;
judging whether the terminal achieves the water-meeting condition once again at regular time intervals (such as 5 seconds) after the terminal is in the water-meeting state, starting timing when the verification fails and the water-meeting condition cannot be achieved, counting the time which passes after the verification fails as the water-leaving time, and clearing the water-leaving time when the terminal achieves the water-meeting condition again.
S1450, comparing the water leaving time information with a preset second time threshold;
a second time threshold (e.g., 30 seconds) is preset in the system to distinguish whether the terminal is actually out of the water-met state. Specifically, the acquired water leaving time is compared with a second time threshold, and whether the water leaving time is greater than a preset second time threshold is judged. The value of the second time threshold can be adjusted according to actual use requirements, for example, when the water leaving condition of the terminal needs to be judged more quickly, the value of the second time threshold can be reduced appropriately; when the terminal is required to be more accurately determined to be out of the water-encountering state so as to reduce misjudgment caused by accidental water leaving (for example, accidental water leaving when drowning and struggling), the value of the first time threshold can be appropriately increased.
S1430, when the water leaving time information is larger than the second time threshold, triggering a preset water leaving prompt instruction;
