Description

TECHNICAL FIELD

[0001] The present application relates to the field of smart watch outdoor protection, in particular, relates to an outdoor monitoring method, system and application based on a smart watch. BACKGROUND

[0002] With the improvement of people's living standards, more and more people are keen on outdoor activities, such as mountaineering, hiking, camping, etc. However, the outdoor environment is complex and changeable, and there are many potential risks, which pose a challenge to the personal safety of participants.

[0003] In the outdoor environment, the weather conditions change rapidly, and extreme weather such as heavy rain, gale, blizzard, and high temperature may suddenly occur, causing secondary disasters such as floods, mudslides, and landslides, which pose a serious threat to the life safety of outdoor personnel. For example, when hiking in the mountains, a sudden heavy rain may trigger a flash flood, and hikers may not be able to detect and avoid it in time, and are easily washed away by the flood. The geographical environment also harbors risks, such as steep slopes, cliffs, turbulent rivers, dense forests, soft sand, and abandoned mines, which may lead to accidents. For example, when crossing a river, if the water flow speed and depth are underestimated, it may lead to a drowning accident; in dense forests, it is easy to lose direction and may encounter attacks from wild animals.

[0004] In addition, everyone's physical condition is different, and people with chronic diseases such as cardiovascular disease, respiratory disease, and motor system disease are more susceptible to the outdoor environment. For example, people with heart disease may experience increased heart burden during high-intensity outdoor activities or in harsh weather, which may lead to serious health problems.

[0005] Some existing smart devices have relatively single functions and cannot fully integrate weather, geographical, and personal physiological data, making it difficult to provide targeted risk warnings and coping strategies, and there are obvious limitations in the face of complex and changeable outdoor environments.

Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0055] The present application provides an outdoor monitoring method based on a smart watch, and a flowchart is shown in FIG. 1. Figure 1 The principle is shown in FIG. 2, and the specific scheme is as follows. Figure 2 The principle is shown in FIG. 2, and the specific scheme is as follows.

[0056] An outdoor monitoring method based on a smart watch, comprising:

[0057] 101, determining the current physical condition of a user and an outdoor area to be visited;

[0058] 102, obtaining weather information and geographic information of the outdoor area through a preset smart watch, and determining potential weather hazard items and geographic hazard items of the outdoor area in a preset time period based on the weather information and the geographic information;

[0059] 103, determining physiological monitoring items to be monitored based on the physical condition, and judging whether the user is suitable for visiting the outdoor area according to the weather hazard items, and / or the geographic hazard items, and / or the physical condition of the user;

[0060] If suitable, corresponding countermeasures are configured in advance for the physiological monitoring items, the weather hazard items and the geographic hazard items;

[0061] 104, when reaching the outdoor area, continuously monitoring through the smart watch and / or a preset monitoring device, and collecting physiological data, position data and surrounding environmental data of the user to the smart watch;

[0062] 105, analyzing whether the physiological monitoring items are abnormal according to the physiological data, analyzing whether the user encounters the weather hazard items according to the environmental data, and analyzing whether the user encounters the geographic hazard items according to the position data and the physiological data; if any of the items is yes, corresponding countermeasures are taken.

[0063] This application's solution addresses the geographical diversity, environmental complexity, and spatial openness of outdoor environments by utilizing wearable smartwatches to monitor and process user physiological data, activity data, and surrounding environmental data. The outdoor area refers to the specific geographical space where the user will engage in outdoor activities. It can be naturally formed areas, such as the areas surrounding mountains, forests, grasslands, deserts, rivers, and lakes, or artificially developed areas containing certain natural elements, such as parks, campsites, and outdoor sports fields. The outdoor area is the target and foundational scenario of the entire outdoor monitoring solution. Identifying the outdoor area is crucial for obtaining unique weather and geographical information to assess potential risks and provide targeted safety guarantees and monitoring services for the user.

[0064] A smartwatch is a wearable smart device, typically worn on the wrist, integrating various sensors and functional modules to connect and communicate with the user's mobile phone or other devices. Integrating multiple sensors and electronic components into a compact device, such as a heart rate sensor, accelerometer, GPS module, barometric pressure sensor, and temperature sensor, enables a wealth of functions within a limited space. Furthermore, it possesses a smart operating system, allowing the installation of various applications to achieve diverse functions, such as receiving notifications, viewing maps, and recording exercise tracks. Simultaneously, it facilitates user interaction with the device through touchscreens, buttons, or voice interaction. In addition, the smartwatch needs to be able to collect and process data acquired by sensors in real time, performing preliminary analysis and judgment, such as calculating heart rate changes, steps taken, and distance traveled. It can also transmit and synchronize data with mobile phones or other devices via wireless communication technologies such as Bluetooth and Wi-Fi, uploading data to the cloud or sharing it with other applications. The monitoring solution in this application fully utilizes the intelligence of smartwatches to cope with complex outdoor environments, providing users with real-time monitoring information and early warning prompts, helping users better understand their own status and surrounding environment, and ensuring the safety and smoothness of outdoor travel.

[0065] In step 101, it is necessary to collect various aspects of the user's physical information, covering basic physical indicators and health status. The specific geographical location must also be clearly defined, which can be a detailed place name, such as Huangshan Scenic Area or Zhangjiajie National Forest Park, or latitude and longitude coordinates. Precise location information allows the smartwatch to more accurately obtain weather and geographical information for that area. Identifying the outdoor area to be visited is crucial for accurately obtaining its weather and geographical information. Different outdoor areas have different climate characteristics and geographical environments; for example, mountainous areas may have steep terrain and large altitude variations, while coastal areas may have risks such as strong winds and high tides. Only by determining the specific area can the smartwatch obtain accurate environmental information from relevant data sources, thereby analyzing potential weather and geographical hazards and providing a basis for subsequent safety measures.

[0066] The basic physical indicators include height, weight, age, etc. These data can be used to assess the basic physical fitness and metabolic level of the user. For example, an older user may have relatively weak endurance and need to arrange rest time more reasonably during outdoor activities; a user with a weight beyond the normal range may have more pressure on the joints during exercise. Health conditions include whether or not the user has chronic diseases such as heart disease, high blood pressure, diabetes, etc., and recent physical conditions such as whether or not the user has a cold, an injury, etc. A user with heart disease needs to pay close attention to the changes in heart rate and blood pressure during outdoor activities; a user with a recent cold may have a weakened immune system and be more susceptible to adverse outdoor environments. According to the user's unique physical condition, determine the physiological indicators that need to be monitored, and provide individual differences for subsequent risk assessment. For example, for a user with diabetes, blood sugar monitoring will be a key physiological monitoring item; for a user with a history of sports injuries, monitoring of the movement data of the relevant injured parts is particularly important. Different physical conditions determine that users have different risk tolerance and adaptability during outdoor activities. Only by accurately understanding these information, can individualized risk assessment be carried out.

[0067] In actual application, the user's physical condition information can be input in the application program matched with the smart watch. For example, age 30, height 175 cm, weight 70 kg, and recently a little cold, no history of chronic diseases. At the same time, the outdoor area to be visited is Huangshan Scenic Area. Through the input of these information, the smart watch can subsequently provide more targeted outdoor monitoring and risk prompts for the user according to the user's physical condition and the environmental characteristics of Huangshan.

[0068] The core of step 102 is to collect and analyze key information of the outdoor area by using the smart watch to provide a basis for subsequent safety measures. The smart watch with pre-set functions is used to complete the information acquisition. The smart watch usually has network connection capability, which can access the network through Wi-Fi, Bluetooth connection to the mobile phone hotspot or built-in mobile data module, and then obtain the required information from the relevant data sources.

[0069] Among them, the preset time period is a pre-set time range, such as 1 hour in the future, 3 hours in the future, 24 hours in the future, etc., which is used to determine the potential risks that may occur in the outdoor area within this time period. The weather hazard item is determined according to the weather information that may cause harm to the user, such as heavy rain that may cause floods, lightning that may cause electric shock, high temperature that may cause heat stroke, etc. The geographical hazard item is based on geographical information analysis of possible dangers, such as steep slopes that may have the risk of slipping or rolling, proximity to rivers that may have the risk of drowning, and geologically unstable areas that may have landslides, mudslides, etc.

[0070] The weather information includes, but is not limited to, temperature, precipitation probability, wind speed, wind direction, humidity, air pressure, etc. These information can help understand the weather conditions of the outdoor area in the preset period, for example, high temperature may cause heatstroke risk, and precipitation may cause road wetness, flood, etc. The geographic information covers topography (such as mountains, plains, valleys, cliffs, etc.), altitude, geological structure, surrounding water system distribution (rivers, lakes, oceans, etc.), vegetation coverage, etc. The geographic information helps to determine the possible geographical risks in the region, such as steep slopes prone to landslides, mudslides, and rivers prone to flood threats. In combination with the changes in the geographical environment under different weather conditions, potential hidden trouble items are determined. For example, in mountainous areas, if it is forecasted to have heavy rain, in combination with the topographic features of the mountainous area, there may be hidden troubles such as landslides and mudslides.

[0071] Regarding weather hidden trouble items. The smart watch can be connected to a meteorological database or a related meteorological service platform to obtain weather data of the outdoor area in the past few years or even decades. These data include temperature, precipitation, wind speed, lightning, etc. in different seasons and time periods. For example, data is obtained from the official database of the meteorological department to understand the frequency and intensity of extreme weather such as heavy rain and strong wind in the region during a specific time period each year. Real-time weather data obtained by the smart watch, such as current temperature, humidity, air pressure, wind speed, wind direction, cloud conditions, etc. are analyzed. For example, if the air pressure suddenly decreases and the humidity rapidly increases, it may indicate that it is about to rain or storm; if the wind speed increases sharply in a short period of time, there may be a strong wind hidden trouble. The watch can access professional numerical weather prediction model data, which is based on principles of atmospheric dynamics, thermodynamics, etc. Through the calculation and simulation of a large amount of meteorological data, the weather conditions in the future period of time are predicted. Thresholds are set for various weather elements according to the human body's tolerance to weather and the safety standards of outdoor activities. For example, when the temperature exceeds 35°C, there may be a risk of heatstroke; when the precipitation intensity exceeds 50 millimeters per hour, it may cause flood disasters; when the wind speed reaches 12 or above, it will pose a serious danger to outdoor activities. The smart watch compares the real-time and predicted weather data obtained with these thresholds to determine whether there is a potential weather hidden trouble item. The weather system in which the outdoor area is located is analyzed, such as whether it is affected by a cyclone, anticyclone, cold front, warm front, etc. For example, when in a cold front passing area, there may be weather changes such as strong wind, temperature drop, and rain, which may pose risks such as catching a cold and slipping; if affected by a cyclone, there may be strong precipitation and strong wind, which requires vigilance against flood and high-altitude falling objects, etc.

[0072] Regarding the geographical hazard item. Through geographic information system (GIS) data, the smart watch obtains the contour map, topographic profile, etc. of the outdoor area, analyzes the terrain undulation, slope, height difference, etc. If the slope exceeds 45 degrees, there may be a risk of falling or rolling; in areas with large height difference, there may be a risk of falling off the cliff. You can refer to geological survey data and related geological databases to understand the geological structure, rock type, soil stability, etc. of the outdoor area. For example, in limestone areas, there may be karst caves, with the risk of collapse; in areas with loose soil, landslides or mudslides may occur. In practical applications, you can also determine specific geological information according to the user's outdoor preferences. For example, if the user likes fishing, you can obtain hydrological data such as rivers, lakes, reservoirs, etc. in the outdoor area and its surroundings, including water level, water flow speed, flow, etc. If it is close to the river and the water level is high, the water flow is turbulent, there is a risk of drowning; at the confluence of rivers or downstream areas, you also need to consider the threat of floods. For example, if the user likes to prepare, use satellite remote sensing images or vegetation information in the field to understand the vegetation coverage type and density in the outdoor area. In dense forests, there may be a risk of getting lost or being attacked by wild animals; while in areas with sparse vegetation such as deserts or grasslands, you may face sandstorms, sunburn, etc. In addition, when determining the geographical hazard item, you need to consider whether there are roads, bridges, mines, etc. in the outdoor area, and whether there are construction, mining, etc. activities around. Close to the construction site may have the risk of falling rocks, mechanical injuries, etc.; in areas with mining activities, there may be ground subsidence, harmful gas leakage, etc. hidden dangers.

[0073] In some embodiments, the weather hazard item includes high-temperature weather hazard, strong wind weather hazard, precipitation weather hazard, low-temperature weather hazard, and lightning weather hazard; the geographical hazard item includes terrain hazard, geological hazard, water area hazard, and vegetation hazard.

[0074] High-temperature weather hazard: usually refers to the environmental temperature is too high, which exceeds the normal tolerance range of the human body, and may cause heatstroke, heatstroke, etc. When the temperature reaches 35°C and above, and the relative humidity is high, the human body has difficulty in heat dissipation, and may appear symptoms such as dizziness, nausea, and fatigue, and even life-threatening in severe cases. In addition, high temperature may also cause dehydration, leading to electrolyte imbalance and affecting normal body functions. At the same time, under high-temperature weather, outdoor equipment such as mobile phones, smart watches, etc. may also malfunction due to overheating, affecting normal use.

[0075] Strong wind weather hazards: Strong winds can directly harm the human body, such as being blown down and causing falls, fractures, etc. When the wind speed reaches a certain level, it may also blow down branches, billboards and other high-altitude objects, causing injury accidents. For some outdoor activities such as hiking and cycling, strong winds will increase the difficulty of travel and reduce the speed of action, and may even cause people to deviate from the route, increasing the risk of getting lost. Strong winds can also cause fires to spread faster, posing a great threat to outdoor personnel and the environment.

[0076] Precipitation weather hazards: Precipitation includes rain, snow, hail and other forms. When the intensity of rainfall is high, it may cause the road to be slippery, increase the probability of falling and falling, and also may cause flood disasters, submerge roads and low-lying areas, and threaten the safety of life. Snow will make the ground snow, making it difficult to walk and easily spraining the ankle, and may also cause a sharp drop in temperature, increasing the risk of frostbite. Hail may directly injure the human body and damage outdoor equipment.

[0077] Low temperature weather hazards: In a low temperature environment, the body loses heat too quickly, which may cause frostbite, commonly seen in fingers, toes, ears and other parts. Prolonged exposure to low temperature environments may also cause respiratory diseases such as colds and pneumonia, and an increased risk of cardiovascular disease. For some devices that need to be operated outdoors, low temperature may affect the battery performance and running stability, such as the shortening of the battery life of smart watches and the inability to use some functions normally.

[0078] Lightning weather hazards: Lightning is a very dangerous weather phenomenon. When encountering lightning outdoors, people are likely to become a discharge channel for lightning if they are in an open area or near tall objects such as trees and power poles, and may be struck by lightning, causing serious personal injury or even death. Even in relatively safe locations, electromagnetic pulses generated by lightning can damage electronic devices, rendering smart watches and other devices inoperable.

[0079] Terrain hazards

[0080] Steep slope: A slope with a steep slope, which is prone to slipping and falling when walking, especially in slippery or rocky conditions. For example, during mountain climbing, encountering a steep slope of more than 60 degrees poses a great risk of climbing and descending.

[0081] Cliff: A terrain with a steep edge and a large drop, which may cause fatal injury if one stumbles near the edge. In some mountain hiking routes, there may be sections near cliffs that require extra caution.

[0082] Canyon: A terrain with steep sides and a narrow middle, which is prone to flash floods during heavy rain, and the signal inside the canyon may be weak, making it difficult to seek help and rescue in case of danger.

[0083] Geological hazards

[0084] Landslide: A mountain rock or soil mass slides down along a weak plane or zone under the action of gravity. It can be triggered by rainfall, earthquakes, human activities, etc., and can bury roads and people, causing serious loss of life and property. When engaging in outdoor activities in mountainous areas, if you find cracks, loose soil and rocks on the slope, it may indicate a risk of landslide.

[0085] Mudflow: A special flood containing a large amount of solid material such as mud and stones, with suddenness, fast flow, large flow, large material capacity and strong destructive power. It often occurs in deep valleys and rugged terrain in mountainous areas and is easily triggered by heavy rain, which can destroy everything along the way and pose a great threat to outdoor activity participants.

[0086] Ground subsidence: In karst areas or underground mined-out areas, the overlying rock and soil mass may suddenly collapse due to the presence of underground cavities. It can cause people to fall into the cavity, resulting in injury and death, and also damage roads and other infrastructure.

[0087] Water hazards

[0088] River: A river with fast-flowing water can sweep people away, leading to drowning accidents. Especially in places without bridges or safe river-crossing facilities, it is very dangerous to cross the river forcibly. In addition, the undercurrent and whirlpool in the river are not easy to detect, increasing the risk of drowning.

[0089] Lake: Some lakes may have complex underwater topography, water temperature stratification, etc., which can easily cause cramps and drowning. When camping or engaging in activities near the lake, it is also possible to slip into the lake if the safety distance is not observed.

[0090] Reservoir: Reservoirs are usually deep and may have a large water level difference, and the surrounding area is generally open, making rescue difficult in the event of an accident. At the same time, the dam of the reservoir may have safety hazards such as leakage and collapse, posing a threat to people in the surrounding area.

[0091] Vegetation hazards

[0092] Dense forest: In a dense forest, it is easy to get lost and difficult to distinguish roads and directions, increasing the difficulty of finding a way out. Moreover, the forest may contain various wild animals such as venomous snakes and ferocious beasts, posing a threat to personal safety.

[0093] Thorn bush: Thorny vegetation areas can easily scratch the skin, affecting movement speed and possibly causing infection. When crossing a thorn bush, if not careful, you may be entangled by the thorns, causing physical injury.

[0094] Toxic plants: Some plants such as poison sumac, datura, etc. are toxic, and contact or accidental ingestion may cause skin allergies, poisoning, and other symptoms, affecting physical health. When outdoors, you need to identify and avoid these toxic plants.

[0095] In step 103, the physiological monitoring items to be monitored are determined based on the physical condition. In step 101, the current physical condition of the user has been determined, which includes basic health information such as whether or not suffering from chronic diseases (such as heart disease, high blood pressure, diabetes, etc.), whether or not having injuries recently, overall physical fitness, etc. According to the physical condition, the physiological indicators that need to be monitored are determined. For healthy people: basic physiological indicators such as heart rate, blood pressure, body temperature, and blood oxygen saturation can be monitored to understand the body's stress response and fatigue level during outdoor activities. For people with specific diseases: for example, heart rate, electrocardiogram, etc. indicators need to be monitored for heart disease patients to detect heart abnormalities in time; diabetes patients need to pay attention to the change of blood sugar level. For people with recent injuries: the pain level and swelling of the injured part may need to be monitored.

[0096] Whether the user is suitable for accessing the outdoor area can be determined by considering multiple factors. In some embodiments, the user's current suitability for accessing the outdoor area is determined by considering the influence degree of the weather risk item on the user's access to the outdoor area, and / or the probability of the user encountering the weather risk item within a preset period of time, and / or the influence degree of the geographical risk item on the user's access to the outdoor area, and / or the probability of the user encountering the geographical risk item within a preset period of time, and / or whether the user's physical condition can implement the corresponding response measures of the weather risk item, and / or whether the user's physical condition can implement the corresponding response measures of the geographical risk item.

[0097] The influence degree can be determined by establishing a special evaluation index system and assigning corresponding scores. By quantifying, the influence degree of each risk item can be converted into a specific score, so that the comprehensive risk can be more intuitively evaluated to determine whether the user is suitable for accessing the outdoor area. In actual application, the scores and indicators can also be adjusted and optimized according to specific circumstances and experience.

[0098] The evaluation index system for weather risk items includes basic indicators, duration, and concurrent effects. Basic indicators such as temperature, wind speed, and lightning frequency. For example, each increase of 1 degree Celsius increases the score by 1 point. The duration refers to the duration of the basic indicator, and different durations represent different evaluation values. The concurrent effect refers to the consequences triggered or concurrent under special basic indicators. Precipitation weather can cause flooding, which can be used as a concurrent effect. Lightning weather may be accompanied by strong convection, and whether it is accompanied by strong convection can be used as a concurrent effect.

[0099] For high-temperature weather hazards, a certain number of points is added for every 1°C increase above 35°C, such as 2 points for 35°C, 5 points for 38°C, and 8 points for 40°C and above. A certain number of points is added for every day of sustained high temperature, such as 3 points for 2 days, and 5 points for 3 days and above. A certain number of points is added for every 10% increase in air humidity above 60%, such as 2 points for 70% humidity, and 4 points for 80% and above. For precipitation weather hazards, a certain number of points is added for every 1mm of precipitation, such as 2 points for light rain (1-10mm), 4 points for moderate rain (10-25mm), 6 points for heavy rain (25-50mm), and 8 points for heavy rain and above (50mm and above). A certain number of points is added for every 12 hours of continuous precipitation, such as 2 points for 12 hours, and 4 points for 24 hours. If flooding has already occurred or there is a high risk of flooding, 8-10 points are added.

[0100] The evaluation index system for geographical hazard items is relatively complex and can be constructed specifically for different geographical hazard items. It can be measured by height, complexity, and whether there is protection, etc. For example,

[0116] Ease of getting lost: 5-8 points for easy to lose direction in the vegetation area, 3-5 points for some risk of getting lost.

[0117] In some embodiments, the influence of the weather hazard item or the geographical hazard item on the physiological monitoring item and the influence of the weather hazard item or the geographical hazard item on the user's access to the outdoor area are evaluated to obtain a first influence degree; if the first influence degree is not lower than a preset influence threshold, the user is currently not suitable for accessing the outdoor area; if the first influence degree is lower than the preset influence threshold, the probability of the user encountering the weather hazard item or the geographical hazard item within a preset period is analyzed; if the probability exceeds a preset probability threshold, it is determined that the user is currently not suitable for accessing the outdoor area; if the probability does not exceed the preset probability threshold, it is determined whether the user's current physical condition can implement the corresponding countermeasures of the weather hazard item or the geographical hazard item; if not, it is determined that the user is currently not suitable for accessing the outdoor area; if yes, it is determined that the user is currently suitable for accessing the outdoor area. The principle is shown in the accompanying Figure 3

[0118] ​First, the first influence degree is evaluated by comprehensively considering the influence degree of the weather hidden danger item or the geographical hidden danger item on the physiological monitoring item and the influence degree on the user's access to the outdoor area. Different weather conditions will have different degrees of influence on human physiological indicators. For example, high-temperature weather can cause the human heart rate to accelerate, blood pressure to rise, body temperature to rise, and other physiological indicators to change, which may exceed the normal range and thus pose a threat to physical health. In high-altitude areas, due to the decrease in oxygen content, the human blood oxygen saturation will decrease, and the heart rate will accelerate to meet the body's demand for oxygen. This influence degree can be determined according to the relationship between altitude and changes in blood oxygen saturation and heart rate. The first influence degree calculated is compared with a preset influence threshold. The preset influence threshold is a limit value set according to a large amount of actual experience and safety standards. If the first influence degree is not lower than the preset influence threshold: it indicates that the weather hidden danger item or the geographical hidden danger item has a very large influence on the user's physical health and outdoor access activities, and there is a high risk, so it is determined that the user is currently not suitable for accessing the outdoor area. If the first influence degree is lower than the preset influence threshold: it indicates that the current hidden danger situation is relatively light, but the probability of encountering hidden danger needs to be further evaluated.

[0119] If the first influence degree is lower than the preset influence threshold, the probability of the user encountering the weather hidden danger item or the geographical hidden danger item within a preset period of time needs to be analyzed. If the probability exceeds a preset probability threshold: it indicates that the user has a high probability of encountering hidden danger within the preset period of time, even if the influence degree of the current hidden danger is relatively low, there is still a high risk, and it is determined that the user is currently not suitable for accessing the outdoor area. If the probability does not exceed the preset probability threshold: it indicates that the user has a low probability of encountering hidden danger, but the user's coping ability still needs to be further considered. Weather hidden danger probability: the probability of weather hidden danger occurrence can be obtained through weather forecasts, meteorological models, etc. For example, according to the forecast of the meteorological department, there is an 80% probability of heavy rain in a certain area within the next 24 hours. Geographical hidden danger probability: for geographical hidden dangers, historical data, geological monitoring, and other information can be combined to evaluate the probability. In some areas where landslides often occur, according to the geological conditions and recent rainfall, the probability of landslides can be predicted. The obtained probability is compared with the preset probability threshold. In practical applications, the preset probability threshold is a probability limit set according to safety requirements and risk tolerance.

[0120] If the probability of encountering the hidden danger does not exceed the preset probability threshold, it is necessary to determine whether the user's current physical condition can implement the corresponding response measures of the weather hidden danger item or the geographical hidden danger item. For high-temperature weather, the response measures may include finding a shady place to rest, supplementing water and electrolytes, etc.; for landslide hidden danger, the response measures may be to evacuate to a safe area as soon as possible. Factors such as the user's age, health status, physical fitness level, etc. need to be considered. For example, for users with heart disease, they may not be able to withstand long outdoor activities in high-temperature weather, and it is also difficult for them to effectively implement response measures; while for users who are physically strong and have rich outdoor experience, they may be more capable of responding to various hidden dangers. If the user's physical condition cannot implement the response measures: even if the probability of encountering the hidden danger is small, the user cannot effectively protect himself when facing the hidden danger, and there is still a great risk, it is determined that the user is not suitable for visiting the outdoor area at present. If the user's physical condition can implement the response measures: based on the previous evaluation results, it is considered that the user has the ability to respond to the hidden dangers that may occur in the current situation, and it is determined that the user is suitable for visiting the outdoor area at present.

[0121] To determine whether the user's current physical condition can implement the corresponding response measures of the weather hidden danger item or the geographical hidden danger item, various means can be used. For example, measuring the user's heart rate, blood pressure, body temperature, blood oxygen saturation, etc. Basic physiological indicators. If the heart rate is too fast or too slow, the blood pressure is abnormal, it may indicate that the body is in an uncomfortable state, and the ability to implement response measures will decrease. Pay attention to the user's cardiopulmonary function indicators such as maximum oxygen uptake, as well as muscle strength, joint mobility, etc. Good cardiopulmonary function and muscle strength help the user to perform response actions such as rapid walking, climbing, etc. when facing weather or geographical hidden dangers, while limited joint mobility may affect the user's action flexibility.

[0122] In actual application, the smart watch can also actively ask the user whether he currently has symptoms of physical discomfort, such as headache, dizziness, chest tightness, shortness of breath, muscle soreness, etc. These symptoms may be early warning signals from the body, even if there is no obvious disease, they may also affect the user's ability to implement response measures. Let the user self-evaluate his current physical fitness and endurance, such as whether he feels tired easily, whether he has enough energy to carry out outdoor activities, etc. The user's subjective feelings can to some extent reflect the actual state of the body, and have reference value for judging his response ability.

[0123] In some embodiments, determining the influence degree assessment of the weather hidden danger item on the physiological monitoring item includes the following: selecting physiological indicators with high weather correlation, such as body temperature, heart rate, blood pressure, and blood oxygen saturation. For example, in extremely cold weather, the change in body temperature is focused on, and in high-altitude areas, blood oxygen saturation is focused on. Referring to medical research data and experimental results, the specific relationship between weather factors and physiological indicator changes is determined. For example, in a high-temperature environment, the heart rate may increase by 10-15 times per minute for every 1°C increase in body temperature; for every 10% increase in humidity, the body temperature will increase by 1-2°C, thereby affecting the physiological state. In addition, different ages, genders, and health conditions of people have different tolerances and reactions to weather. The elderly, children, and people with chronic diseases such as cardiovascular diseases are more sensitive to extreme weather, and the weight of the influence degree needs to be adjusted according to the specific user situation when evaluating.

[0124] In some embodiments, determining the influence degree assessment of the weather hidden danger item on the user accessing the outdoor area includes the following: classifying common weather hidden dangers by severity, such as general heavy rain, heavy rain, and heavy rain; wind is divided into 3-4 levels of breeze, 5-6 levels of strong wind, and 7 levels and above of gale, etc., and different levels have different effects on outdoor activities. Analyze the impact of different weather conditions on user walking, vision, equipment use, and other outdoor activities. For example, heavy fog weather has low visibility, which can severely limit the user's vision and increase the risk of getting lost and colliding; heavy snow may cause deep snow on the road, making it difficult to walk, and even unable to proceed. Combined with historical data and meteorological models, the probability of dangerous events occurring under specific weather conditions is evaluated, such as the probability of lightning strikes in thunderstorm weather and the probability of floods caused by heavy rainfall, and the higher the probability, the greater the influence degree on the user accessing the outdoor area.

[0125] In some embodiments, the influence degree assessment of the geographical hidden danger item on the physiological monitoring item includes: determining the influence of different geographical hidden danger factors, such as high altitude, steep slope, wetland, and desert, on physiological indicators.

[0126] According to sports medicine and physiology research, understand the body's stress response in different geographical environments. In a desert high-temperature environment, the body loses water quickly, which can cause blood concentration and blood pressure changes, and in severe cases, can cause heatstroke and other diseases. The influence degree can be evaluated according to the relationship between water loss and physiological indicator changes. Consider the user's ability to adapt to specific geographical environments. People who have lived in the plains for a long time will have a more intense physiological response when they first arrive in high-altitude areas than people who have lived in high-altitude areas for a long time. Users with poor adaptability are more affected by the influence degree of geographical hidden dangers on physiological monitoring items.

[0127] In some embodiments, the influence degree assessment of the geographical hidden danger item on the user's access to the outdoor area includes: measuring the terrain complexity by indicators including slope, elevation difference, and terrain undulation. Assessing whether the geology is stable, such as whether there are landslides, mudslides, ground collapses, and other hidden dangers. Through geological exploration reports, historical geological disaster records, etc., determine the possibility and harm degree of geological disasters, and the influence of unstable geology on the user's access to the outdoor area is great. Special geographical environment obstacles: for wetlands, swamps, jungles, and other special geographical environments, analyze their hindrance to the user's passage, equipment carrying, navigation positioning, etc. Wetlands can make the feet sink into the mud, increase the walking resistance and physical consumption; it is easy to lose direction in the jungle, and there may be wild animals threatening, which will seriously affect the user's access to the outdoor area.

[0128] When the user arrives at the predetermined outdoor area, the monitoring work is automatically started. In this process, the smart watch, as a commonly used personal device for the user, and the additional preset monitoring device jointly undertake the task of data collection. The smart watch has certain basic monitoring functions, while the preset monitoring device is set to more comprehensively and accurately obtain various types of data. They cooperate with each other to meet the needs of all-around monitoring of the user. The smart watch is built-in with various sensors such as heart rate sensors, accelerometers, and gyroscopes. With the built-in global positioning system (GPS) or other positioning technology (such as Beidou satellite navigation system), the smart watch can accurately determine the user's geographic location, including longitude, latitude, and altitude information. Although the smart watch has certain physiological monitoring capabilities, there are still limitations in some cases. The preset monitoring device worn on the body can provide more comprehensive and accurate physiological data. The data collected by the preset monitoring device worn on the body needs to be transmitted to the smart watch through wireless communication technology. After receiving data from different devices, the smart watch will integrate and process these data. It will store physiological data, location data, and environmental data in a certain format and time sequence to form a complete and orderly data set. In this way, the user can conveniently view his own data on the smart watch, and these data also provide a reliable basis for subsequent analysis and decision-making, so as to discover potential problems in time and take corresponding measures.

[0129] Step 105 is to analyze whether the physiological monitoring item is abnormal according to the physiological data, analyze whether the user encounters weather hidden danger item according to the environmental data, and analyze whether the user encounters geographical hidden danger item according to the location data and physiological data; if any item is yes, take corresponding measures.

[0130] According to the physiological data analysis, whether the physiological monitoring item is abnormal, for each physiological monitoring item, there is a corresponding normal range, which can be personalized according to factors such as age, gender, physical condition, etc. The system will analyze the collected physiological data in real time or periodically, compare the current physiological data with the set normal range and threshold. If the data of a certain physiological monitoring item exceeds the normal range and reaches the warning threshold, such as the heart rate suddenly rises above 130 times / min, or the body temperature exceeds 38℃, etc., it can be determined that the physiological monitoring item is abnormal.

[0131] According to the weather hazard item and its characteristics determined in step 102, the current environmental data is matched. For example, if there is a "high temperature weather hazard" in the weather hazard item, and the set high temperature threshold is 35℃, when the environmental data shows that the current temperature reaches or exceeds 35℃, it can be preliminarily judged that the user may encounter high temperature weather hazard. In addition to single weather element data, the relationship and trend between multiple environmental data also need to be considered. For example, when judging whether to encounter precipitation weather hazard, not only the rainfall amount needs to be considered, but also the duration of rainfall, the change of rainfall intensity and the weather situation of the surrounding area, etc.

[0132] According to the weather hazard item and its characteristics determined in step 102, the current environmental data is matched. For example, if there is a "high temperature weather hazard" in the weather hazard item, and the set high temperature threshold is 35℃, when the environmental data shows that the current temperature reaches or exceeds 35℃, it can be preliminarily judged that the user may encounter high temperature weather hazard. In addition to single weather element data, the relationship and trend between multiple environmental data also need to be considered. For example, when judging whether to encounter precipitation weather hazard, not only the rainfall amount needs to be considered, but also the duration of rainfall, the change of rainfall intensity and the weather situation of the surrounding area, etc.

[0133] In the present application, each physiological monitoring item abnormality, weather hazard item or geographical hazard item is pre-configured with a response measure. Once it is determined that the user has any of the physiological monitoring item abnormality, encounters a weather hazard item or a geographical hazard item, the system will take appropriate action according to the response measure pre-configured in step 103 for the specific situation. For example, if it is a physiological monitoring item abnormality such as high heart rate, the response measure can be to remind the user to stop activity, rest in place, and provide some simple relaxation and recovery suggestions; if it is a weather hazard of strong wind, the response measure can be to suggest that the user seek a solid building or other safe shelter to avoid. The smart watch will convey the information of the response measure to the user through sound, vibration, screen prompt, etc., to ensure that the user can understand and take action in time. At the same time, if the user is in a dangerous state and cannot take effective measures by himself, the smart watch can also automatically send a help information to the pre-set emergency contact or rescue agency, including the user's location, current abnormal situation, etc., so as to obtain timely external help and support.

[0134] For example, when the body temperature exceeds the normal range, the user is prompted to drink more warm water to supplement water and prevent dehydration. When the blood pressure is too low, the user is reminded to change the body position slowly to avoid dizziness or syncope caused by sudden standing up. When the weather hazard item is heavy rain weather, the user can be pre-arranged to find a safe indoor place. If cracks are found on the ground or signs of loose mountain, the user is prompted to quickly move away from the area and move to a place with higher terrain and stable geology.

[0135] In some specific embodiments, the physiological parameter abnormality item corresponding to each weather hazard item and geographical hazard item is pre-determined, which is an abnormal physiological parameter caused by encountering the weather hazard item or the geographical hazard item; when reaching the outdoor area, the physiological parameter abnormality item corresponding to the weather hazard item and the geographical hazard item of the outdoor area is preferentially monitored; when a certain physiological parameter of the user is abnormal, it is determined whether the abnormal physiological parameter is the physiological parameter abnormality item corresponding to the weather hazard item or the geographical hazard item; if so, it is determined whether it is a certain weather hazard item in combination with the environmental data, and whether it is a certain geographical hazard item in combination with the position data.

[0136] Determine the physiological parameter abnormality items corresponding to each weather risk item and geographical risk item. Different weather conditions will have different effects on human physiology. Special geographical environment will also affect the physiological state of the human body. When the user arrives at an outdoor area, the system will preferentially monitor the physiological parameter abnormality items corresponding to the weather risk items and geographical risk items that may exist in the outdoor area. This is because these physiological parameter abnormality items are closely related to the potential risks of the current outdoor environment, and by focusing on these parameters first, the user's possible dangers can be discovered more timely. Compare the current abnormal physiological parameters with the physiological parameter abnormality items corresponding to the pre-determined weather risk items and geographical risk items. If it is judged that the abnormal physiological parameters may be related to weather risks, the system will comprehensively analyze the current environmental data (such as temperature, humidity, wind speed, wind direction, rainfall, etc.). For example, if the heart rate abnormally rises and the environmental temperature exceeds 35°C and the humidity is large, it is more likely that the physiological response is caused by high-temperature weather, so it is judged that the user may encounter a high-temperature weather risk item. When suspecting that the abnormal physiological parameters are related to geographical risks, the system will combine the user's location data (such as latitude and longitude, altitude, terrain, etc.) to make a judgment. For example, if the user's blood oxygen saturation decreases, and the location data shows that the user is in a high-altitude area, it can be judged that the user may encounter a high-altitude geographical risk item.

[0137] In some embodiments, map data, geological data, route data, and historical area data of the outdoor area are obtained; from the historical area data, areas related to safety risks are filtered to obtain historical risk areas, and the current marked risk areas of the outdoor area are taken as first risk areas; in combination with the weather information of the outdoor area, the areas that may have safety risks within a preset time period are determined according to the geological data to obtain geological risk areas; the historical risk areas, the first risk areas, and the geological risk areas are marked in the map data to determine geographical risk items, and path planning is performed in combination with the route data to plan a moving route that avoids the risk areas.

[0138] Obtain detailed map data of the outdoor area, including information such as terrain, road distribution, building location, water distribution, etc. These data can be obtained through geographic information systems (GIS), satellite remote sensing images, professional map drawing institutions, etc. Geological data contains information such as geological structure, rock type, soil properties, and underground water level of the outdoor area. These data are usually collected and analyzed by geological exploration departments, research institutions, etc. Route data records the existing routes in the outdoor area, including roads, trails, paths, etc. including length, direction, slope, traffic conditions, etc. These data can help plan the user's movement path in the outdoor area. For example, some routes may be suitable for hiking, while others may be more suitable for cycling, and route data can provide users with reference. Historical area data covers records of various events and situations that have occurred in the outdoor area in the past, such as natural disasters (landslides, mudslides, floods, etc.), accident locations, and records of dangerous areas. These data can be obtained from local government departments, emergency management agencies, historical archives, etc.

[0139] Select areas related to safety hazards from historical area data, which may be locations where disasters or accidents have occurred in the past, or areas known to have potential dangers. For example, areas where landslides have occurred, low-lying areas prone to flooding, etc. are identified as historical hazard zones. The currently marked hazard zones in the outdoor area are considered as the first hazard zone. These marked hazard zones may be determined through on-site investigation, sign identification, etc., such as setting warning signs on dangerous cliff edges or marking areas that may be dangerous. Combine weather information of the outdoor area, and determine areas that may have safety hazards in the preset period according to geological data. For example, if the current weather information shows that there has been a lot of rainfall recently, and the geological data indicates that the soil in this area is relatively loose and the geological structure is unstable, it can be inferred that geological disasters such as landslides and mudslides may occur in this area within the preset period, thus determining these areas that may have safety hazards as geological hazard zones. Mark the historical hazard zones, the first hazard zone, and the geological hazard zones in the map data. By marking on the map, various safety hazard zones in the outdoor area can be visually displayed. These marked hazard zones constitute the geographic hazard items, and users can clearly understand which areas have potential dangers by viewing the map. Combine route data and plan a path according to the marked hazard zones. The goal of planning is to avoid these hazard zones and plan a relatively safe movement route for the user. For example, if a route passes through a historical hazard zone or a geological hazard zone, it will be avoided during path planning, and other relatively safe routes will be selected. When planning the path, factors such as route length, difficulty, and traffic conditions can also be considered to ensure that the planned route is both safe and suitable for the user's actual situation.

[0140] In some embodiments, when planning a path, it is determined whether a moving route can be planned to avoid the historical hazard area, the first hazard area and the geological hazard area. If yes, it is determined that the user is currently suitable for accessing the outdoor area. If no, the risk coefficient of the historical hazard area is evaluated. When the risk coefficient is in a preset safety interval, it is determined that the user is currently suitable for accessing the outdoor area after determining that a moving route can be planned to avoid the first hazard area and the geological hazard area. If the risk coefficient is not in the preset safety interval, it is determined that the user is currently not suitable for accessing the outdoor area. The safety interval is set according to the risk coefficient. The principle is shown in the accompanying Figure 4

[0141] When planning a path for a user to access an outdoor area, the primary goal is to completely avoid the historical hazard area, the first hazard area and the geological hazard area. These hazard areas include areas where dangerous events have occurred in the past (historical hazard area), areas that have been clearly marked as dangerous (first hazard area), and areas that may be dangerous in a preset period of time according to geological data and current weather forecasts (geological hazard area). If a moving route can be successfully planned that completely avoids these hazard areas, it means that the user can avoid known and potential dangers with a high probability when they are active in the outdoor area, and therefore it can be determined that the user is currently suitable for accessing the outdoor area.

[0142] When a moving route cannot be planned that completely avoids the three types of hazard areas, the next step of evaluation is needed. First, the risk coefficient of the historical hazard area is evaluated. This risk coefficient is determined based on factors such as the frequency and severity of dangerous events in the historical hazard area, and the current state of the area. For example, if a landslide has occurred in an area in the past, and there are no significant improvements in the geological conditions of the area in the near future, and there are signs of another landslide, the risk coefficient of the area will be high. Conversely, if the danger has been reduced through management, the risk coefficient will also decrease accordingly.

[0143] The safety interval is set according to the evaluation criteria of the risk coefficient, and is a safe range. When the risk coefficient is in the safety interval, the historical hazard area of the area is relatively safe, and it can be analyzed whether a moving route can be planned to avoid the first hazard area and the geological hazard area. If the risk coefficient of the historical hazard area is not in the preset safety interval, it means that even if only the historical hazard area is passed, the user also faces a high risk. The preset safety interval is a limit value set according to past experience, safety standards, etc., and is used to measure whether the degree of danger is acceptable.

[0144] ​Similarly, if a moving route that avoids the first hidden danger area and the geological hidden danger area cannot be planned, it means that the user is difficult to avoid contact with the dangerous area when the user is active in the outdoor area, and is not suitable for visiting. For example, a certain historical hidden danger area has occurred serious flood disasters many times, and the current danger coefficient is higher than the preset safety coefficient, or the first hidden danger area and the geological hidden danger area cannot be avoided in any way when planning the route, so the user may encounter danger when going to the outdoor area, and therefore is not suitable for visiting.

[0145] The application also provides an outdoor monitoring system based on a smart watch, a module schematic diagram of which is shown in the accompanying Figure 5 The system comprises:
