[0049] The purpose, features and advantages of this application will be further described in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is: obtaining acceleration information and movement direction information to determine the child's path information;

[0053] According to a preset spatial positioning model, the child path information and the preset initial starting point coordinates are spatially positioned to determine the target child coordinates, wherein the spatial positioning model is obtained by training a preset model to be trained using starting point coordinate samples, path information samples, and end point coordinate labels;

[0054] If the target child coordinates are within the preset indoor danger warning area, the preset warning plan is executed.

[0055] In this embodiment, the application uses the dangerous area warning device as the execution subject. For the convenience of description, it is specifically described below as "device".

[0056] Because the existing technology determines the basic location of children through the GPS function of smart watches, it does not effectively monitor and alarm potential danger areas in indoor environments, resulting in the inability to prevent children from approaching dangerous areas.

[0057] The present application provides a solution, which uses starting point coordinate samples, path information samples and end point coordinate labels to train a preset model to be trained to obtain a spatial positioning model. When obtaining acceleration information and movement direction information and determining the child's path information, the target child's coordinates are obtained through positioning the spatial positioning model based on the child's path information and the preset initial starting point coordinates. When the target child's coordinates are within a preset indoor danger warning area or the child's height is not within the indoor safety height range, the preset warning plan is executed, thereby realizing the function of issuing an early warning when the child approaches a potential danger area in the indoor environment, thereby achieving the beneficial effect of protecting children from danger areas indoors.

[0058] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a dangerous area warning device, etc. The following takes the dangerous area warning device as an example to illustrate this embodiment and the following embodiments.

[0059] Based on this, the embodiment of the present application provides a dangerous area early warning method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the dangerous area warning method of the present application.

[0060] In this embodiment, the dangerous area early warning method includes steps S10 to S30:

[0061] Step S10, acquiring acceleration information and movement direction information, and determining child path information;

[0062] It should be noted that the acceleration information is provided by an accelerometer sensor, reflecting the change of the child's movement speed. The movement direction is provided by a gyroscope or magnetometer sensor, reflecting the change of the child's movement direction.

[0063] It can be understood that by analyzing the acceleration and movement direction data, the movement path of the child over a certain period of time can be constructed.

[0064] In a feasible implementation, step S10 may include:

[0065] Obtain acceleration information and movement direction information, determine and record the child's path information;

[0066] When the child path information passes through the preset initial starting point coordinates, the child path information is re-recorded.

[0067] It is understandable that when the child's moving path passes through the preset initial starting point coordinates, the device will restart recording the child's path information to ensure that the child's location can be updated and tracked in a timely manner.

[0068] Step S20, spatially locating the child path information and the preset initial starting point coordinates according to a preset spatial positioning model to determine the target child coordinates, wherein the spatial positioning model is obtained by training a preset model to be trained using starting point coordinate samples, path information samples and end point coordinate labels;

[0069] It should be noted that the preset spatial positioning model is a mathematical model for converting path information into specific spatial coordinates. This model is based on a machine learning algorithm and learns how to accurately predict the position through a large amount of training data (such as starting point coordinate samples, path information samples and end point coordinate labels). The initial starting point coordinates are the position coordinates when the child starts to move, and are the reference points for spatial positioning. The spatial positioning is to convert the child's path information into specific spatial coordinates by applying the spatial positioning model, thereby determining the child's current position. The target child coordinates are the child's current position coordinates obtained by spatial positioning. The starting point coordinate samples are the known starting position coordinates used when training the model, which help the model learn how to track the path from the starting point. The path information samples are the known moving path data used when training the model, which help the model learn how to parse and understand the path information. The end point coordinate label is the known end point position coordinate corresponding to the path information sample, which is used to train the model so that it can accurately predict the end point of the path.

[0070] It can be understood that by applying the spatial positioning model, the device can calculate the child’s current spatial position based on the child’s movement path and starting point coordinates, thereby achieving real-time tracking and positioning of the child’s position.

[0071] Step S30: If the target child coordinates are within the preset indoor danger warning area, a preset warning plan is executed.

[0072] It should be noted that the preset indoor danger warning areas are some predefined areas in the indoor environment, such as kitchens, balconies, etc. where there may be dangers. The preset warning scheme is that when the system detects that a child has entered the danger warning area, it will trigger the preset warning measures.

[0073] It is understandable that the device can issue a timely warning when a child is in potential danger, alert the guardian, and take appropriate protective measures to ensure the safety of the child.

[0074] In a feasible implementation, step S30 may include:

[0075] Analyze the target child coordinates to obtain the child's horizontal coordinates and the child's height;

[0076] Determining whether the horizontal coordinates of the child are within a preset indoor danger warning area;

[0077] If the horizontal coordinates of the child are within the indoor danger warning area, a vibration reminder is performed and a warning message is sent to a preset communication device;

[0078] Determining whether the height of the child is within a preset indoor safety height range;

[0079] If the height of the child is not within the indoor safe height range, an early warning message is sent to a preset communication device.

[0080] It should be noted that the target child coordinates are the coordinates of the child's current location calculated by the spatial positioning model. The child's horizontal coordinates are the projection coordinates of the target child coordinates on the horizontal plane, which are used to determine whether the child is in a dangerous area. The child's height is the position information of the target child coordinates in the vertical direction, which is used to determine whether the child is in a safe height range. The preset indoor danger warning area is some areas that may have safety hazards set in advance in the indoor environment, such as places near fire sources, water sources, stairs, etc. The preset indoor safety height range is a height range set according to the indoor environment to ensure that the child is at a safe height. The vibration reminder is a vibration generated by a smart device (such as a watch, a mobile phone, etc.) to remind children to pay attention to safety. The warning information is information containing the child's current location and danger prompts, which is sent to the guardian. The preset communication device is a guardian's device that is set in advance to receive the warning information, such as a mobile phone, a tablet computer, etc.

[0081] It is understandable that the device first analyzes the coordinates of the target child and decomposes them into horizontal coordinates and height information. Then, the device checks whether the horizontal coordinates of the child are within the preset indoor danger warning area. If within the area, the device will alert the child by vibration and send a warning message to a preset communication device. Next, the device checks whether the height of the child is within the preset indoor safety height range. If the height of the child is not within the indoor safety height range, the device will send a warning message to the preset communication device.

[0082] The present embodiment provides a dangerous area warning method, which uses starting point coordinate samples, path information samples and end point coordinate labels to train a preset model to be trained to obtain a spatial positioning model. When the acceleration information and movement direction information are obtained to determine the child's path information, the target child's coordinates are obtained through positioning the spatial positioning model based on the child's path information and the preset initial starting point coordinates. When the target child's coordinates are within the preset indoor dangerous warning area, the preset warning plan is executed, thereby realizing the function of warning when the child approaches a potential dangerous area in the indoor environment, thereby achieving the beneficial effect of protecting children from dangerous areas indoors.

[0083] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated later. On this basis, before step S10, the dangerous area warning method further includes:

[0084] Get the starting point coordinate sample, path information sample and end point coordinate label;

[0085] Inputting the starting point coordinate sample and the path information sample into a preset model to be trained;

[0086] Analyzing the displacement corresponding to the path information sample according to the model to be trained to obtain target displacement information;

[0087] Determine the end point coordinate sample according to the starting point coordinate sample and the target displacement information;

[0088] Determine the difference between the endpoint coordinate sample and the endpoint coordinate label to obtain a positioning loss value;

[0089] If the positioning loss value does not meet the preset loss standard, return to the step of analyzing the displacement corresponding to the path information sample according to the model to be trained to obtain the target displacement information, and stop training until the positioning loss value meets the loss standard to obtain a spatial positioning model that meets the loss standard.

[0090] It should be noted that the starting point coordinate sample is the known starting position coordinate used when training the model, which helps the model learn how to track the path from the starting point. The path information sample is the known moving path data used when training the model, which helps the model learn how to parse and understand the path information. The end point coordinate label is the known end point position coordinate corresponding to the path information sample, which is used to train the model so that it can accurately predict the end point of the path. The model to be trained is an untrained model that needs to be trained with input data to achieve the expected performance. The target displacement information is the moving distance and direction information calculated based on the path information sample, which is used to train the model. The positioning loss value is a numerical value that measures the difference between the end point coordinates predicted by the model and the actual end point coordinate label, which is used to evaluate the accuracy of the model. The loss standard is a preset threshold. When the positioning loss value is less than this threshold, it is considered that the model training has achieved the expected effect.

[0091] It is understandable that in order to train a spatial positioning model, it is necessary to first collect starting point coordinate samples, path information samples, and end point coordinate labels. Then, the starting point coordinate samples and path information samples are input into a preset model to be trained. The model will analyze the displacement corresponding to the path information sample to obtain the target displacement information. Next, based on the starting point coordinate sample and the target displacement information, the end point coordinate sample can be determined. After that, the difference between the end point coordinate sample and the end point coordinate label is compared to calculate the positioning loss value. If this positioning loss value does not meet the preset loss standard, it is necessary to repeatedly adjust the model parameters and re-analyze the displacement corresponding to the path information sample until the positioning loss value meets the loss standard, and finally obtain a spatial positioning model that meets the requirements.

[0092] The dangerous area early warning method also includes:

[0093] Analyzing the child's path information to obtain horizontal motion path information;

[0094] According to the horizontal motion path information, a heat map of children's indoor motion and data on children's step count are obtained;

[0095] A children's indoor activity report is obtained based on the children's indoor exercise heat map and the children's step count data, and the children's indoor activity report is sent to a preset communication device.

[0096] It should be noted that the child path information is the movement trajectory data of the child within a certain time period calculated by the spatial positioning model. The horizontal motion path information is the projection of the child path information on the horizontal plane, reflecting the movement of the child in the horizontal direction. The child indoor motion heat map is a graph generated based on the horizontal motion path information, which indicates the frequency of children's activities in different indoor areas by color depth. The child step data is the statistical information of the number of children's walking steps calculated based on the horizontal motion path information, reflecting the intensity of children's activities. The child indoor activity report is a report that integrates the motion heat map and step data, which comprehensively reflects the children's indoor activities. The preset communication device is a device of the guardian who receives the activity report set in advance, such as a mobile phone, tablet computer, etc.

[0097] It is understandable that by analyzing the path information of the child, the movement path information of the child in the horizontal direction can be extracted. Then, based on this horizontal movement path information, the movement heat map and step count data of the child indoors can be generated. Finally, these heat maps and step count data are summarized into a child indoor activity report, and the report is sent to a preset communication device.

[0098] The dangerous area early warning method also includes:

[0099] Calibrate the initial starting point coordinates;

[0100] Obtain indoor danger warning coordinates and calibrate indoor danger warning areas;

[0101] Obtain children's height reference value and calibrate indoor safe height range.

[0102] It should be noted that the calibration of the initial starting point coordinates is to select a point in the indoor environment as the starting point, record its coordinate information, and use it as a reference for subsequent positioning and path tracking. The indoor danger warning coordinates are the coordinate information of some points in the indoor environment that may have safety hazards, such as coordinates near fire sources, water sources, stairs, etc. The calibration of the indoor danger warning area is to connect the collected indoor danger warning coordinates and delineate an area as a danger warning area to remind children and guardians to pay attention to safety. The child height reference value is a value measured based on the child's actual height, which is used to assess the safe height of the child in the indoor environment. The calibration of the indoor safety height range is to delineate a height range based on the child height reference value and the specific conditions of the indoor environment to ensure that children will not be in danger due to height issues when they are indoors.

[0103] It is understandable that the coordinates of an initial starting point are first determined as a reference, and then the coordinate information of potential safety hazards in the indoor environment is collected, and these coordinates are connected to mark a danger warning area. At the same time, it is also necessary to obtain the height reference value of the child and calibrate an indoor safe height range based on this value to ensure the safety of children when they are indoors.

[0104] For example, in order to help understand the implementation process of the dangerous area warning method obtained by combining this embodiment with the above-mentioned embodiment 1, the following embodiments are provided herein:

[0105] The child’s movement data, including acceleration and movement direction, is obtained through the built-in sensors of the smart watch (such as accelerometers and gyroscopes).

[0106] Based on these data, the movement path information of the child within a certain period of time is determined.

[0107] Use the preset spatial positioning model, combined with the initial starting point coordinates and the child's path information, to perform spatial positioning and determine the child's current coordinate position.

[0108] This spatial positioning model is obtained through training. The training process includes inputting starting point coordinate samples, path information samples and end point coordinate labels, analyzing the displacement corresponding to the path information samples, calculating the positioning loss value, and continuously adjusting the model parameters until the positioning loss value meets the preset standards.

[0109] Determine whether the child’s current coordinates are within the preset indoor danger warning area.

[0110] If the child's horizontal coordinates are within the danger warning area, the smart watch will vibrate to remind the child and send a warning message to the preset communication device (such as the parent's mobile phone).

[0111] At the same time, the smart watch will also determine whether the child’s height is within the preset safety height range. If it is not within this range, it will also send an early warning message.

[0112] If the child's horizontal coordinates are within the danger warning area, or the child's height is not within the safe height range, the smart watch will execute the preset warning plan, including vibration reminders and sending warning messages.

[0113] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the dangerous area warning method of the present application.
