It should be understood that the electronic device 10 and the terminal 11 shown in fig. 1 are a smart phone, the terminal 12 is a smart watch, and the rescue center platform end 13 is a smart PC end, which are only an example and do not constitute a limitation on the types of the electronic device and the terminals in the embodiment of the present application.
The following describes in detail an emergency help-seeking method for understanding the disclosure of the embodiments of the present application.
Referring to fig. 2, fig. 2 is a schematic flow chart of an emergency help-seeking method disclosed in the embodiment of the present application. The emergency help-seeking method can comprise the following steps:
201. when early warning information used for indicating emergency is detected, the electronic equipment is continuously positioned within preset time, field information of the site where the electronic equipment is located is acquired, and the positioning information and the field information of the electronic equipment acquired within the preset time are obtained.
In the embodiment of the present application, the emergency includes, but is not limited to, an earthquake, a flood, a typhoon, a fire, a rainstorm, a tsunami, and the like, which may be early-warned emergency. In practical application, when a related early warning information distribution platform (for example, a national early warning information distribution center, or early warning information distribution platforms at all levels of meteorological, ocean, and geological disasters) distributes emergency early warning, the electronic device may receive newly distributed early warning information through various channels such as short messages, mails, information push of various installed application programs (for example, disaster early warning application programs and news application programs), and the like. It should be understood that the pre-warning information may generally serve as a pre-warning for an emergency when the emergency has not occurred (e.g., a river breaking into a bank), or when the emergency has occurred but has not caused a significant impact (e.g., typhoon has not entered into the field, or buffer time between the occurrence of an earthquake and the arrival of seismic waves at the ground). Therefore, the electronic device actively triggers step 201 immediately after detecting the warning message, and can generate and send out the distress message in advance before the emergency occurs or the influence is enlarged.
As an optional implementation manner, the electronic device may analyze the received warning information, determine an information type and a response level of the warning information, and enter a corresponding warning mode according to the information type and the response level of the warning information. In different alert modes, the electronic device may directly output alert information matching the alert mode, and the types of alert information may include, but are not limited to, vibration, sound, and flashing light. Illustratively, if the electronic device determines from the warning information: and 4.0 grade, the electronic equipment can output warning sound effect and vibration frequency preset for 4.0 grade earthquake. And, if the determined key information is: earthquake, 6.0, it is easy to understand that the vibration frequency output by the electronic device can be larger than the vibration frequency of 4.0. Therefore, the implementation of the optional implementation mode can quickly respond to the early warning information and warn the user to take refuge in time through various warning modes.
In addition, optionally, the electronic device may perform keyword analysis based on text content of the warning information to identify an information type and a response level indicated by the keyword, and may also determine the information type of the warning information by combining with a quick sending of a sending object of the warning information, for example, if the electronic device receives a short message sent by the earthquake center of the province of Sichuan, the warning information is the earthquake warning information.
In this embodiment of the application, the preset duration may be set manually, or determined according to the information type and the response level of the warning information, for example, the buffering time from the issuance of the warning information to the actual damage of the earthquake on the ground is much shorter than the buffering time of the actual influence of the rainstorm on a certain area, so the preset duration corresponding to the earthquake may be shorter than the preset duration corresponding to the typhoon, which is not specifically limited.
In this embodiment of the application, the electronic device may perform positioning through a positioning module such as a Global Positioning System (GPS), WIFI or bluetooth, to obtain longitude and latitude information of a location where the electronic device is located, and may also detect height information of the location where the electronic device is located through an air pressure sensor, which is not specifically limited. The electronic device collects the field information of the site where the electronic device is located, and the method can include the following steps: the electronic device captures a picture and records a video of a scene through the capturing module, records an audio through the recording module (e.g., a microphone), and collects environmental parameters such as temperature and humidity of the scene through the sensor module (e.g., a temperature and humidity sensor and an air pressure sensor), which is not limited in this respect.
202. And generating a positioning track of the electronic equipment according to the positioning information.
In this embodiment of the application, the positioning information may include a plurality of positions obtained by continuously positioning the electronic device within a preset duration, and a positioning track of the electronic device within the preset duration may be generated according to a positioning sequence of the positions in time and corresponding latitude and longitude information and height information, where the positioning track is, for example: spring field primary school teaching building → spring field primary school playground → spring field primary school gymnasium. If the electronic equipment is carried by the user, the positioning track can be used for representing the moving path of the user within the preset time length, so that the dynamic position and the action intention of the user can be analyzed more accurately.
203. And integrating the positioning track and the field information into distress information.
As an optional implementation manner, if the field information includes audio/video information recorded by the electronic device, step 203 may specifically be:
detecting the data transmission rate of the current communication network environment of the electronic equipment; if the data transmission rate is greater than or equal to a preset first transmission rate, integrating the positioning track and the audio and video information into distress information; if the data transmission rate is less than the first transmission rate, compressing the audio and video information to obtain the compressed audio and video information; integrating the positioning track and the compressed audio and video information into help seeking information; the information size of the compressed audio and video information is in a direct proportion relation with the data transmission rate, and the first transmission rate can be the transmission rate for ensuring that the electronic equipment normally sends the audio and video data.
Therefore, by implementing the optional implementation mode, the information size of the audio and video information can be adaptively adjusted according to the data transmission condition of the current communication network environment, so that the electronic equipment preferentially selects to integrate the complete audio and video information with the positioning track when the network condition is good, the help seeking information is ensured to intuitively convey sufficient information quantity, and the method is more beneficial to the outside to accurately know the field condition and implement rescue; and when the network condition is not good, the compressed audio and video information and the positioning track can be integrated and transmitted, so that the success rate of data transmission is improved while a certain information amount is ensured.
Further, the audiovisual information may include a plurality of image frames corresponding to different time stamps, and the positioning track may include a plurality of positioning points corresponding to different time stamps. As an optional implementation manner, the electronic device may perform intra-frame compression processing on each of the plurality of image frames on the basis that the total number of the plurality of image frames is not changed, so as to remove spatial data redundancy of each image frame based on the correlation between pixels of the image frame, and obtain compressed audio/video information.
Or, as another optional implementation, the electronic device extracts a target number of key frames from the plurality of image frames by performing image feature analysis and matching on the plurality of image frames, and obtains compressed audio and video information according to the key frames.
The image feature ratio contained in the key frame is greater than or equal to the preset ratio, the matching degree between the key frame and the historical frame is less than the preset matching degree, and the historical frame is an image frame adjacent to the key frame in terms of time. The electronic device may use algorithms such as scale-invariant feature transform (SIFT), speeded up robust feature algorithms (SURF), Histogram of Oriented Gradients (HOG), or corner detection algorithm (FAST) to perform image feature analysis and matching on a plurality of continuous image frames, and the specifically selected algorithm is not limited.
Therefore, the key frames containing important features can be screened from the original multiple image frames, and the relevance among the key frames is small, so that redundant image frames which are continuous in time and small in difference are removed, and the information size of audio and video information is further adjusted while the important image frames are reserved.
Correspondingly, integrating the positioning track and the compressed audio and video information into distress information may specifically be: determining a positioning point corresponding to each key frame from the positioning track according to the timestamp corresponding to each key frame, wherein the timestamp corresponding to the positioning point is the same as the timestamp corresponding to the key frame; marking the key frames by utilizing the positioning points corresponding to each key frame to obtain a target number of marked key frames; and integrating the positioning track and the key frames marked by the target number into SOS information.
It can be understood that the positioning point may be used to represent a position of the user, and the marked key frame may be used to represent an image frame captured by the user and an environment where the user is located when the user is located at a certain position, so that the position and the image frame are associated with each other, readability of the distress information can be increased, and subsequent visual display is facilitated.
Optionally, the preset ratio and the preset matching degree may be in an inverse relationship with the information size of the compressed audio/video information, that is, if it is determined that the smaller the information size of the compressed audio/video information is, the greater the adaptability of both the preset ratio and the preset matching degree is, the fewer the key frames that can satisfy the conditions of the preset ratio and the preset matching degree are; on the contrary, if the size of the information is larger, the preset ratio and the preset matching degree can be adaptively reduced, and the number of key frames meeting the conditions of the preset ratio and the preset matching degree is more.
Still further, as an optional implementation manner, the obtaining of the compressed audio/video information according to the key frame may specifically be: and if the data transmission rate is less than the second transmission rate, generating key text information corresponding to each key frame based on the image characteristics of each key frame, and taking the key text information corresponding to the target number of key frames as the compressed audio/video information. The second transmission rate may be a transmission rate that ensures that the electronic device normally transmits image data, and the second transmission rate is smaller than the first transmission rate.
Correspondingly, the positioning track and the compressed audio and video information are integrated into distress information, and the method comprises the following steps: determining a positioning point corresponding to each key frame from the positioning track according to the timestamp corresponding to each key frame, wherein the timestamp corresponding to the positioning point is the same as the timestamp corresponding to the key frame; marking the key text information corresponding to the key frames by utilizing the positioning points corresponding to each key frame to obtain the target number of marked key text information; and determining the key text information marked by the positioning track and the target number as the help-seeking information.
For example, if the image features of the key frame include a runway, a banner raising platform, a lawn, and a face, and the face can be recognized as a face of a teacher, the key text information corresponding to the key frame may be: playground, teacher. Therefore, based on the key text information, the relevant personnel can easily know that the user is on the playground and the teacher accompanies the user. Therefore, according to the important features of the key frames, concise text key information is generated, the information size of the distress message can be further reduced, and the method is suitable for the extremely poor condition of the network.
Optionally, after the electronic device sends the distress message to the preset terminal, the preset terminal can visually display the distress message. To better understand the effect of the labeling of the key frames or key text messages on the visualization of distress messages, the following description will be made in conjunction with fig. 3a, 3b and 3 c.
In one case, as shown in fig. 3a, fig. 3a is a schematic view illustrating a visualization of distress information on a preset terminal in the embodiment of the present application, and after receiving the distress information sent by the electronic device, the preset terminal may directly guide the positioning track 31 into the map 30 for display. At this time, the live information is complete audio-video information, so that the video 32 can be directly played. In another case, as shown in fig. 3B, fig. 3B is a schematic view of another visualization of the distress message on the preset terminal in the embodiment of the application, where the distress message received by the preset terminal includes a positioning track 31, and 2 marked key frames a and B. It can be seen that a key frame a can pop up at the positioning point 311 and a key frame B can pop up at the positioning point 312 in the positioning track 31, and images captured at different positioning points are visually shown. In another case, as shown in fig. 3C, fig. 3b is a schematic view illustrating a visualization of help-seeking information on another preset terminal in the embodiment of the present application, where the help-seeking information received by the preset terminal includes a positioning track 31, and 2 marked key text information C and key text information D. As can be seen, the positioning point 311 may pop up the key text information C, and the positioning point 312 may pop up the key text information D, so that the key text information generated based on the images captured at different positioning points can be displayed, and certain readability is also provided.
In addition, still optionally, the audio and video information may further include audio information recorded by the electronic device through the recording module. The electronic equipment can also identify the voice and the content of the audio information to obtain an audio text, extract keywords from the audio text to obtain audio keywords, and add the audio keywords into the compressed audio and video information. It can be understood that because the audio information recorded by the electronic equipment usually includes voice and environmental noise, the audio keyword is extracted from the audio information to add the compressed audio and video information, so that the simple audio keyword can be sent to the preset terminal, the size of the sent information is reduced, a user at the preset terminal does not need to listen to the complete audio, or the voice in the audio and the key information are difficultly distinguished, and the readability of the help seeking information is improved.
204. And sending the distress message to a preset terminal.
In this embodiment of the application, the electronic device may send the distress message to the preset terminal in various manners such as a short message, a mail, and a communication application, which is not limited specifically.
In the embodiment of the present application, the electronic device may periodically perform the above steps 201 to 204 until the electronic device becomes a transmission stop state. Accordingly, in step 201, the preset duration may be a preset period duration. For example, if the electronic device performs the above steps 201 to 204 every 30 seconds, the electronic device in step 201 will obtain the positioning information and the field information collected within 30 seconds.
The stop sending state may include that the electronic device cannot send out the distress message due to a poor communication network, or the electronic device may recognize the safety message from the voice of the user, which is not particularly limited. Illustratively, when the electronic device detects that the user voice is "i have been secured", and recognizes "secured" as the security information from the voice, the steps 201 to 204 are not executed. Therefore, the electronic equipment periodically generates and sends the distress message, the real-time performance and the continuity of the distress message can be ensured, and more state information of the trapped people is provided for the outside. In addition, the generation and the sending of the help-seeking information can be stopped under the condition that the network is poor or the user is safe, so that unnecessary resource and power consumption are reduced.
Therefore, the method described in the figure 2 is implemented, the user does not need to manually trigger and send the help-seeking information, and unnecessary operation time is reduced; in addition, more information before the emergency occurs can be transmitted to the outside, the timeliness of calling for help outwards in the emergency is improved, and the guarantee effect on the life safety of the user is achieved.
Referring to fig. 4, fig. 4 is a schematic flow chart of another emergency help-seeking method disclosed in the embodiment of the present application.
401. When early warning information for indicating an emergency is detected, judging whether the electronic equipment is currently in a dangerous area indicated by the early warning information, if so, executing a step 402; if not, the flow is ended.
In the embodiment of the present application, it can be understood that the emergency generally occurs in a certain region, for example, the region S1 is a landing region of a typhoon, while the region S2 is not located in a region affected by the typhoon, and the weather condition is only light rain when the typhoon passes through, so people in the region S2 are not in the dangerous region of the typhoon, and no emergency countermeasure for the typhoon is needed. As can be seen, step 401 is implemented to reduce unnecessary power consumption when the electronic device is not in a dangerous area corresponding to an emergency, so as to generate and transmit help-seeking information more specifically.
As an optional implementation manner, step 401 may specifically be:
analyzing the early warning information to obtain the central position and the influence range of the emergency; positioning the electronic equipment to obtain the current position of the electronic equipment; judging whether the current position is within the influence range or not according to the relative position relation between the central position and the current position; if the electronic equipment is in the influence range, judging that the electronic equipment is currently in the dangerous area indicated by the early warning information; and if the electronic equipment is not in the influence range, judging that the electronic equipment is not in the dangerous area currently.
The relative position relationship between the center position and the current position may include a distance and an orientation (e.g., east, south, west, north, etc.) between the center position and the current position, which is not limited herein. For example, if a mountain fire occurs in a mountain area and the influence range is approximately 5 kilometers around the mountain area, it is easy to know that the electronic device is not within the influence range if the current position of the electronic device is more than 5 kilometers away from the mountain area. Therefore, the central position and the influence range of the emergency can be obtained by directly analyzing the early warning information, and whether the current position of the electronic equipment is within the influence range is judged based on the central position and the influence range, so that the decision speed is increased.
402. Judging whether the electronic equipment meets the monitoring condition, if so, executing a step 403; if not, the flow is ended.
In this embodiment of the application, the monitoring condition may include that the electronic device is carried by the user, or the electronic device is not carried by the user but the electronic device monitors the user within a corresponding monitoring range. More specifically, the electronic device may collect sensing data (e.g., a distance from the sensing layer to the skin of the human body, human body pulsation data, etc.) through at least one sensing layer disposed in an area of the electronic device that is in contact with the skin of the human body, and determine that the electronic device is carried by the user when the collected sensing data and the sensing data of the electronic device are in a carrying state. Or, the electronic device can detect whether the user is shot in the shooting range of the electronic device by starting the shooting module. Or, the electronic device may further determine whether the user's body is sensed within the sensing range of the electronic device through the infrared sensor, which is not limited specifically.
As can be seen, by implementing the step 402, the electronic device generates the distress message only when monitoring the user, and also can reduce unnecessary power consumption when the user cannot be monitored.
Optionally, if the electronic device is not currently located in the dangerous area indicated by the early warning information, the safety information may be sent to the preset terminal to inform a user of the external electronic device that the user is in a safe state. Or if the electronic equipment does not meet the monitoring condition, prompt information for indicating that the user is not monitored can be sent to the preset terminal, so that the preset terminal can respond to the prompt information and preferentially select to contact other terminals of the user, the situation that related personnel still try to establish communication with the electronic equipment when the electronic equipment is not beside the user is avoided, and the influence of unnecessary connection time on timely rescue is reduced.
403. Continuously positioning the electronic equipment within the preset time, and acquiring the field information of the site where the electronic equipment is located to obtain the positioning information and the field information of the electronic equipment acquired within the preset time.
404. And generating a positioning track of the electronic equipment according to the positioning information.
405. And integrating the positioning track and the field information into distress information.
406. And sending the distress message to a preset terminal.
