Description

Technical Field

[0001] The present application relates to the field of outdoor protection for smart watches, and more specifically, to an outdoor monitoring method, system and application based on smart watches. Background Art

[0002] As people's living standards improve, more and more people are keen on outdoor activities, such as mountain climbing, hiking, camping, etc. However, the outdoor environment is complex and changeable, with many potential risks, which poses a challenge to the personal safety of participants.

[0003] In outdoor environments, weather conditions change rapidly. Extreme weather such as heavy rain, strong winds, heavy snow, and high temperatures may suddenly occur, causing secondary disasters such as floods, mudslides, and landslides, posing a serious threat to the lives and safety of outdoor personnel. For example, a sudden rainstorm while hiking in the mountains may cause mountain torrents. If hikers fail to detect and avoid them in time, they are likely to be washed away by the floods. The geographical environment also hides dangers. Steep slopes, cliffs, turbulent rivers, dense jungles, soft sand, and abandoned mines may all lead to accidents. For example, when crossing a river, if the water flow speed and water depth are underestimated, drowning accidents may occur; in the dense jungle, it is easy to get lost and may be attacked by 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 outdoor effects. For example, people with heart disease will experience increased stress on their hearts when engaging in high-intensity outdoor activities or encountering bad weather, which may lead to serious health problems.

[0005] Some existing smart devices have relatively simple functions and are unable to fully integrate weather, geographical and personal physiological data. They are also unable to provide targeted risk warnings and response strategies, and have obvious limitations when facing complex and changeable outdoor environments. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] This application proposes an outdoor monitoring method based on a smart watch, and the flow chart is as shown in the attached Figure 1 The principle is shown in the attached Figure 2 The specific plan is as follows: An outdoor monitoring method based on a smart watch, comprising: 101. Predetermine the user’s current physical condition and the outdoor area to be visited; 102. Obtain weather information and geographic information of the outdoor area through a preset smart watch, and determine potential weather hazards and geographic hazards of the outdoor area within a preset period of time by combining the weather information and the geographic information; 103. Determine the physiological monitoring items to be monitored based on the physical condition, and judge whether the user is currently suitable to visit the outdoor area according to the weather potential hazard items, and / or the geographical potential hazard items, and / or the user's physical condition; If appropriate, corresponding response measures are configured in advance for abnormal physiological monitoring items, weather potential hazards, and geographical potential hazards; 104. After arriving at the outdoor area, continuous monitoring is performed through a smart watch and / or a preset monitoring device, and the user's physiological data, location data, and surrounding environment data are aggregated to the smart watch; 105. Analyze whether physiological monitoring items are abnormal based on physiological data, analyze whether the user encounters weather hidden dangers based on comprehensive environmental data, and analyze whether the user encounters geographical hidden dangers based on comprehensive location data and physiological data; if any one of the items is yes, take corresponding countermeasures.

[0023] The solution of this application targets the geographical diversity, environmental complexity and spatial openness of the outdoor environment, and uses wearable smart watches to monitor and process the user's physiological data, motion data and surrounding environment data. The outdoor area refers to the specific geographical space where the user is about to go for outdoor activities. It can be a naturally formed area, such as mountains, forests, grasslands, deserts, rivers and lakes, etc., or it can be an artificially developed area that contains certain natural elements, such as parks, camping sites, outdoor sports venues, etc. The outdoor area is the target object and basic scene of the entire outdoor monitoring plan. The outdoor area is determined to obtain weather, geography and other information unique to the area in order to assess potential risks and provide users with targeted security and monitoring services.

[0024] A smartwatch is a wearable smart device that is usually worn on the wrist and integrates a variety of sensors and functional modules, which can connect and communicate with the user's mobile phone or other devices. Integrating a variety of sensors and electronic components in a compact small device, such as a heart rate sensor, an acceleration sensor, a GPS module, an air pressure sensor, a temperature sensor, etc., can achieve rich functions in a limited space. In addition, it has an intelligent operating system and can install various applications to achieve a variety of functions, such as receiving notifications, viewing maps, recording movement trajectories, etc. At the same time, it is convenient for users to interact with the device through touch screens, buttons or voice interactions. In addition, smart watches need to be able to collect and process data obtained by sensors in real time, and perform preliminary analysis and judgment, such as calculating heart rate changes, exercise steps, exercise distance, etc. And it can transmit and synchronize data with mobile phones or other devices through wireless communication technologies such as Bluetooth and Wi-Fi, and upload data to the cloud or share with other applications. The monitoring scheme of this application makes full use of the intelligence of smart watches 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.

[0025] In step 101, it is necessary to collect various aspects of the user's physical information, covering basic physical indicators and health conditions. And it is necessary to clarify the specific geographical location, which can be a detailed place name, such as Huangshan Scenic Area, Zhangjiajie National Forest Park, etc., or longitude and latitude coordinates. Accurate location information enables the smart watch to obtain weather and geographical information of the area more accurately. The purpose of clarifying the outdoor area to be visited is to accurately obtain weather information and geographical information of the area. Different outdoor areas have different climatic characteristics and geographical environments. For example, there may be steep terrain and large changes in altitude in mountainous areas, and there may be risks such as strong winds and tides at the seaside. Only by determining the specific area can the smart watch obtain accurate environmental information from relevant data sources, and then analyze potential weather and geographical risks, and provide a basis for subsequent safety measures.

[0026] Basic physical indicators include height, weight, age, etc. These data can be used to assess the user's basic physical fitness and metabolic level. For example, older users may have relatively weak endurance and need to arrange rest time more reasonably when doing outdoor activities; users whose weight exceeds the normal range may bear greater pressure on their joints during exercise. Health status includes whether they have chronic diseases, such as heart disease, hypertension, diabetes, etc., as well as recent physical conditions, such as whether they have caught a cold or been injured. Users with heart disease need to pay special attention to changes in heart rate and blood pressure when doing outdoor activities; users who have recently caught a cold may be more susceptible to the harsh outdoor environment due to decreased immunity. According to the user's unique physical condition, determine the physiological indicators that need to be monitored in focus to provide individual differences for subsequent risk assessment. For example, for users with diabetes, blood sugar monitoring will become a key physiological monitoring item; and for users with a history of sports injuries, sports data monitoring of related injured parts is particularly important. Different physical conditions determine the different risk tolerance and adaptability of users in outdoor activities. Only by accurately understanding this information can personalized risk assessment be carried out.

[0027] In actual application, you can enter your physical condition information in the application of the smart watch. For example, age 30, height 175cm, weight 70kg, a slight cold recently, no history of chronic diseases. At the same time, enter the outdoor area you are about to visit as Huangshan Scenic Area. By entering this information, the smart watch can provide more targeted outdoor monitoring and risk warnings for the user based on his physical condition and the environmental characteristics of Huangshan.

[0028] The core of step 102 is to use smart watches to collect and analyze key information of outdoor areas to provide a basis for subsequent safety measures. Use smart watches with preset functions to complete information acquisition. Smart watches usually have network connection capabilities and can access the network through Wi-Fi, Bluetooth, mobile phone hotspots, or built-in mobile data modules, and then obtain the required information from relevant data sources.

[0029] Among them, the preset time period is a pre-set time range, such as the next 1 hour, the next 3 hours, the next 24 hours, etc., which is used to determine the potential hazards that may occur in the outdoor area during this time period. Weather hazard items are weather conditions that may cause harm to users based on weather information, such as heavy rain may cause floods, lightning may cause electric shock hazards, and high temperatures may cause heat stroke. Geographical hazard items are possible dangers analyzed based on geographic information, such as steep slopes may have the risk of slipping and rolling, near rivers may have the risk of drowning, and geologically unstable areas may have landslides and mud-rock flows.

[0030] Among them, weather information includes but is not limited to temperature, precipitation probability, wind speed, wind direction, humidity, air pressure, etc. This information can help understand the weather conditions of the outdoor area during the preset period. For example, high temperature may cause the risk of heat stroke, and precipitation may cause slippery roads, floods and other problems. Geographic information covers topography (such as mountains, plains, canyons, cliffs, etc.), altitude, geological structure, distribution of surrounding water systems (rivers, lakes, oceans, etc.), vegetation coverage, etc. Geographic information helps to determine the possible geographical risks in the area, such as steep slopes are prone to landslides and mudslides, and rivers may be threatened by floods. Combined with the possible changes in the geographical environment under different weather conditions, potential hidden dangers are determined. For example, in mountainous areas, if heavy rain is forecast, combined with the terrain characteristics of the mountainous areas, there may be hidden dangers such as landslides and mudslides.

[0031] About weather hazards. Smart watches can be connected to meteorological databases or related meteorological service platforms to obtain weather data for outdoor areas over the past few years or even decades. These data include temperature, precipitation, wind speed, lightning and other information in different seasons and time periods. For example, data can be obtained from the official database of the meteorological department to understand the frequency and intensity of extreme weather such as heavy rain and strong winds in the area during a specific time period each year. Use the real-time weather data obtained by the smart watch, such as the current temperature, humidity, air pressure, wind speed, wind direction, cloud conditions, etc. for analysis. For example, if the air pressure drops suddenly and the humidity rises rapidly, it may indicate that rain or storms are coming; if the wind speed increases sharply in a short period of time, there may be a risk of strong winds. The watch can access professional numerical weather forecast model data. These models are based on the principles of atmospheric dynamics and thermodynamics. Through the calculation and simulation of a large amount of meteorological data, they predict the weather conditions for a period of time in the future. And set thresholds for various weather elements based on the human body's tolerance to weather and the safety standards for outdoor activities. For example, when the temperature exceeds 35°C, there may be a risk of heat stroke; when the precipitation intensity exceeds 50 mm per hour, it may cause floods; when the wind speed reaches level 12 or above, it will cause serious danger to outdoor activities. The smartwatch compares the real-time and predicted weather data obtained with these thresholds to determine whether there are potential weather hazards. Analyze the weather system in the outdoor area, such as whether it is affected by cyclones, anticyclones, cold fronts, warm fronts and other weather systems. For example, when in a cold front transit area, there may be weather changes such as strong winds, cooling, and rainfall, and there are risks such as colds and slips; if affected by a cyclone, there may be heavy precipitation and strong winds, and you need to be alert to hidden dangers such as floods and falling objects from high altitudes.

[0032] About geographical hazards. Smart watches use geographic information system (GIS) data to obtain contour maps, topographic profiles, etc. of outdoor areas, and analyze the undulations, slopes, and elevation differences of the terrain. If the slope exceeds 45 degrees, there may be a risk of slipping or rolling; in areas with large elevation differences, there may be a risk of falling off a cliff. You can refer to geological survey data and relevant geological databases to understand the geological structure, rock type, soil stability, and other information of outdoor areas. For example, there may be caves in limestone areas, which may pose a risk of collapse; in areas with loose soil, landslides or mudslides may occur. In actual applications, specific geological information can also be determined based on the user's outdoor preferences. For example, if the user likes fishing, hydrological data such as rivers, lakes, and reservoirs in and around the outdoor area can be obtained, including water level, water flow speed, and flow rate. If you are close to a river with a high water level and a turbulent flow, there is a risk of drowning; at the confluence of rivers or downstream areas, the threat of floods must also be considered. For another example, if the user likes to prepare, satellite remote sensing images or on-site vegetation information can be used to understand the vegetation coverage type and density in the outdoor area. In dense forests, there may be risks of getting lost or being attacked by wild animals; in deserts or grasslands with sparse vegetation, there may be problems such as sandstorms and sunburn. In addition, when determining geographical hazards, it is necessary to consider whether there are man-made facilities such as roads, bridges, and mines in the outdoor area, as well as whether there are construction and mining activities in the surrounding area. There may be risks such as falling rocks and mechanical injuries near construction sites; in areas with mining activities, there may be hidden dangers such as ground collapse and harmful gas leakage.

[0033] In some specific embodiments, weather hazard items include high temperature weather hazards, strong wind weather hazards, precipitation weather hazards, low temperature weather hazards, and lightning weather hazards; geographical hazard items include terrain hazards, geological hazards, water hazards, and vegetation hazards.

[0034] High temperature weather hazards: usually refers to the environment temperature being too high, beyond the normal tolerance range of the human body, which may cause health problems such as heat stroke and heat stroke. When the temperature reaches 35°C or above and the relative humidity is high, it is difficult for the human body to dissipate heat, and it is easy to experience heat stroke symptoms such as dizziness, nausea, and fatigue, which may even be life-threatening in severe cases. In addition, high temperatures may also cause dehydration, imbalance the body's electrolytes, and affect the body's normal functions. At the same time, in hot weather, outdoor equipment such as mobile phones and smart watches may also malfunction due to overheating, affecting normal use.

[0035] Hidden dangers of strong winds: Strong winds may cause direct harm to the human body, such as blowing people down and causing falls, fractures, etc. When the wind speed reaches a certain level, it may also blow down high-altitude objects such as tree branches and billboards, causing injuries. For some outdoor activities, such as hiking and cycling, strong winds will increase the difficulty of travel, reduce the speed of action, and may even cause people to deviate from the route, increasing the risk of getting lost. Strong winds may also cause fires and accelerate the spread of fires, posing a huge threat to outdoor personnel and the environment.

[0036] Precipitation weather hazards: Precipitation includes rain, snow, hail and other forms. When the rainfall intensity is high, it may cause slippery roads, increase the probability of slipping and falling, and may also cause floods, submerging roads and low-lying areas, threatening people's lives. Snowfall will cause snow to accumulate on the ground, making it difficult to walk and easy to sprain the ankle. It may also cause a sudden drop in temperature and increase the risk of frostbite. Hail may directly injure the human body and damage outdoor equipment.

[0037] Hidden dangers of low temperature weather: In low temperature environments, the body loses heat too quickly, which may cause frostbite, which is common in fingers, toes, ears and other parts. Being in a low temperature environment for a long time may also cause respiratory diseases such as colds and pneumonia, and increase the risk of cardiovascular diseases. For some devices that need to be operated outdoors, low temperatures may affect their battery performance and operating stability. For example, the battery life of smart watches is shortened, and some functions may not work properly.

[0038] Hidden dangers of lightning weather: Lightning is an extremely dangerous weather phenomenon. When encountering lightning outdoors, if people are in an open area or close to tall objects such as trees and electric poles, they can easily become discharge channels for lightning and be struck by lightning, causing serious personal injury or even death. Even in a relatively safe location, the electromagnetic pulses generated by lightning may damage electronic equipment and make devices such as smart watches lose their functions.

[0039] Terrain hazards Steep slope: A steep slope is prone to slipping and rolling when walking, especially in slippery or gravel conditions. Slipping and rolling may cause serious injuries. For example, when climbing a mountain, if you encounter a steep slope of more than 60 degrees, there are great risks in both climbing and descending.

[0040] Cliff: A terrain with steep edges and a large drop. If you are not careful when approaching the edge of a cliff, you may fall off the cliff and cause fatal injuries. In some mountain hiking routes, there may be sections close to cliffs, so you need to be extra careful.

[0041] Canyon: The terrain is steep on both sides and narrow in the middle, which is prone to flash floods during heavy rains. In addition, the signal inside the canyon may be weak. Once in danger, it is difficult to call for help and be rescued.

[0042] Geological hazards Landslide: As the rock or soil of a mountain slides downward along a certain weak surface or weak zone under the action of gravity, it may be caused by factors such as rainfall, earthquakes, and human activities, which will bury roads and people, causing serious loss of life and property. When doing outdoor activities in mountainous areas, if you find cracks on the slopes, loose soil and rocks, etc., there may be a risk of landslide.

[0043] Debris flow: a special type of torrent containing a large amount of solid materials such as mud, sand, and rocks, characterized by suddenness, fast flow, large volume, large material capacity, and strong destructive power. It often occurs in mountainous areas with deep valleys and steep terrain. It is easily triggered by heavy rains and will destroy everything along the way, posing a huge threat to people doing outdoor activities.

[0044] Ground collapse: In karst areas or underground mining areas, due to the existence of underground cavities, the rock and soil above may suddenly collapse, which may cause people to fall into the cavities, causing casualties, and also damage roads and other infrastructure.

[0045] Water hazards Rivers: Fast-flowing rivers may sweep people away and cause drowning accidents. It is especially dangerous to force a river crossing in places where there are no bridges or safe crossing facilities. In addition, undercurrents and whirlpools in rivers are not easy to detect, increasing the risk of drowning.

[0046] Lakes: Some lakes may have complex underwater terrain and water temperature stratification, which can easily cause cramps and drowning. When camping or doing activities near a lake, if you do not pay attention to a safe distance, you may slip into the lake.

[0047] Reservoirs: Reservoirs are usually deep and may have large water level differences. The surrounding area is generally relatively empty, so rescue is difficult in the event of an accident. At the same time, the dams of reservoirs may have safety hazards, such as leakage and collapse, which pose a threat to people around them.

[0048] Vegetation hazards Dense forest: In a dense forest, it is easy to get lost and difficult to identify the road and direction, which increases the difficulty of finding a way out. In addition, there may be various wild animals in the forest, such as poisonous snakes and beasts, which pose a threat to personnel safety.

[0049] Thorn bushes: areas covered with thorns can easily scratch the skin, slow down movement, and cause infection. If you are not careful when walking through thorn bushes, you may get entangled in the thorns and suffer physical injuries.

[0050] Toxic plants: Some plants, such as poison sumac and datura, are toxic. Contact or accidental ingestion may cause skin allergies, poisoning and other symptoms, affecting your health. When you are outdoors, you need to identify and avoid these toxic plants.

[0051] In step 103, the physiological monitoring items to be monitored are determined based on the physical condition. The user's current physical condition has been determined in step 101, which includes basic health information, such as whether the user suffers from chronic diseases (such as heart disease, hypertension, diabetes, etc.), whether the user has been injured recently, and the overall physical condition of the body. Determine the physiological indicators that need to be monitored based on the physical condition. For healthy people: Generally, 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. People with specific diseases: For example, heart disease patients need to focus on monitoring heart rate, electrocardiogram and other indicators to detect heart abnormalities in a timely manner; diabetic patients need to pay attention to changes in blood sugar levels. People who have been injured recently: may need to monitor the pain level and swelling of the injured area.

[0052] To determine whether the user is suitable to visit the outdoor area, multiple factors may be considered comprehensively. In some specific embodiments, whether the user is currently suitable to visit the outdoor area is determined based on the degree of influence of weather hazards on the user's visit to the outdoor area, and / or the probability of the user encountering weather hazards within a preset period of time, and / or the degree of influence of geographical hazards on the user's visit to the outdoor area, and / or the probability of the user encountering geographical hazards within a preset period of time, and / or whether the user's physical condition can implement the corresponding countermeasures for the weather hazards, and / or whether the user's physical condition can implement the corresponding countermeasures for the geographical hazards.

[0053] The degree of impact can be determined by establishing a dedicated evaluation index system and assigning corresponding scores. Through quantification, the degree of impact of each hidden danger item can be converted into a specific score, so as to more intuitively evaluate the comprehensive risk and determine whether the user is suitable to visit the outdoor area. In actual applications, the scores and indicators can also be adjusted and optimized according to specific circumstances and experience.

[0054] The evaluation index system for weather hazards includes basic indicators, duration, and concurrent effects. Basic indicators include temperature, wind speed, number of lightning strikes, etc. For example, the score increases by 1 point for every 1 degree Celsius increase in temperature. Duration refers to the duration of the basic indicator, and different durations represent different evaluation values. Concurrent effects refer to the consequences that are triggered or paralleled under special basic indicators. Precipitation weather can cause floods, which can be used as a concurrent effect. Thunderstorm weather may be accompanied by strong convection, and whether it is accompanied by strong convection can be used as its concurrent effect.

[0055] For high temperature weather hazards, the unit is Celsius. For every 1°C increase of 35°C and above, a certain number of points will be added, such as 2 points for 35°C, 5 points for 38°C, and 8 points for 40°C and above. For every day of continuous high temperature, a certain number of points will be added, such as 3 points for 2 days, and 5 points for 3 days and above. For every 10% increase in humidity above 60%, a certain number of points will be added, such as 2 points for 70% humidity, and 4 points for 80% and above humidity. For precipitation weather hazards, the unit of precipitation is millimeters. Light rain (1-10 mm) is 2 points, moderate rain (10-25 mm) is 4 points, heavy rain (25-50 mm) is 6 points, and torrential rain and above (more than 50 mm) is 8 points.

[0068] In some specific embodiments, the first impact degree is evaluated by comprehensively considering the impact degree of weather hidden danger items or geographical hidden danger items on physiological monitoring items and the impact degree of weather hidden danger items or geographical hidden danger items on the user's visit to the outdoor area; if the first impact degree is not lower than the preset impact threshold, the user is currently not suitable for visiting the outdoor area; if the first impact degree is lower than the preset impact threshold, the probability of the user encountering weather hidden danger items or geographical hidden danger items within the preset time period is analyzed: if the probability exceeds the preset probability threshold, it is determined that the user is currently not suitable for visiting 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 hidden danger items or geographical hidden danger items; if not, it is determined that the user is currently not suitable for visiting the outdoor area; if so, it is determined that the user is currently suitable for visiting the outdoor area. The principle is as shown in the attached figure. Figure 3 shown.

[0069] First, the first impact degree is evaluated by comprehensively considering the impact degree of weather hidden danger items or geographical hidden danger items on physiological monitoring items and the impact degree on the user's visit to the outdoor area. Different weather conditions will have different degrees of impact on the physiological indicators of the human body. For example, high temperature weather may cause the human body's heart rate to increase, blood pressure to rise, body temperature to rise, etc., and the changes in these physiological indicators may exceed the normal range, thereby posing a threat to physical health. In high-altitude areas, due to the decrease in oxygen content, the human body's blood oxygen saturation will decrease, and the heart rate will increase to meet the body's demand for oxygen. This impact degree can be determined based on the relationship between altitude and changes in blood oxygen saturation and heart rate. The calculated first impact degree is compared with the preset impact threshold. The preset impact threshold is a limit value set based on a large amount of practical experience and safety standards. If the first impact degree is not lower than the preset impact threshold: it means that the weather hidden danger item or geographical hidden danger item has a very large impact on the user's physiological health and outdoor visit activities, and there is a high risk. At this time, it is determined that the user is currently not suitable for visiting the outdoor area. If the first impact degree is lower than the preset impact threshold: it means that the current hidden danger situation is relatively mild, but the probability of encountering hidden dangers still needs to be further evaluated.

[0070] If the first impact level is lower than the preset impact threshold, it is necessary to analyze the probability of the user encountering a weather hazard or a geographical hazard within the preset time period. If the probability exceeds the preset probability threshold, it means that the user is very likely to encounter a hazard within the preset time period. Even if the impact level of the current hazard is relatively low, there is still a high risk, and the user is determined to be unsuitable for visiting the outdoor area at present. If the probability does not exceed the preset probability threshold, it means that the user is less likely to encounter a hazard, but the user's coping ability needs to be further considered. Weather hazard probability: The probability of weather hazards can be obtained through weather forecasts, meteorological models, and other means. 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. Geographic hazard probability: For geographical hazards, the probability can be evaluated by combining historical data, geological monitoring, and other information. In some areas where landslides often occur, the probability of landslides can be predicted based on geological conditions and recent rainfall conditions. 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.

[0071] If the probability of encountering hidden dangers does not exceed the preset probability threshold, it is necessary to determine whether the user's current physical condition can implement the corresponding countermeasures for weather hidden dangers or geographical hidden dangers. For hot weather, countermeasures may include finding a cool place to rest, replenishing water and electrolytes, etc.; for landslide hazards, countermeasures may be evacuating to a safe area as soon as possible. It is necessary to consider factors such as the user's age, health status, and physical fitness level. For example, for users with heart disease, they may not be able to withstand long-term outdoor activities in hot weather, and it is difficult to effectively implement countermeasures; while for users with strong bodies and rich outdoor experience, they may be more capable of dealing with various hidden dangers. If the user's physical condition cannot implement countermeasures: it means that even if the probability of encountering hidden dangers is small, the user cannot effectively protect himself when facing hidden dangers, and there is still a great risk. It is determined that the user is currently not suitable for visiting the outdoor area. If the user's physical condition can implement countermeasures: based on the previous evaluation results, it is believed that the user is capable of dealing with possible hidden dangers under the current circumstances, and it is determined that the user is currently suitable for visiting the outdoor area.

[0072] There are many ways to determine whether the user's current physical condition is capable of implementing the corresponding countermeasures for weather or geographical hazards. For example, measure the user's basic physiological indicators such as heart rate, blood pressure, body temperature, and blood oxygen saturation. If the heart rate is too fast or too slow, or the blood pressure is abnormal, it may indicate that the body is in an uncomfortable state and the ability to implement countermeasures 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 users perform countermeasures such as fast walking and climbing when facing weather or geographical hazards, while limited joint mobility may affect the user's flexibility.

[0073] In actual applications, the smartwatch can also proactively ask the user whether they currently have symptoms of physical discomfort, such as headache, dizziness, chest tightness, shortness of breath, muscle aches, etc. These symptoms may be warning signals from the body, and even if there is no obvious disease, they may affect the user's ability to implement coping measures. Allow users to self-assess their current physical fitness and endurance, such as whether they feel easily fatigued, whether they have enough energy for outdoor activities, etc. The user's subjective feelings can reflect the actual state of the body to a certain extent, and have reference value for judging their coping ability.

[0074] In some embodiments, determining the degree of impact of weather hidden danger items on physiological monitoring items includes the following: selecting physiological indicators with high weather correlation, such as body temperature, heart rate, blood pressure, blood oxygen saturation, etc. For example, in extremely cold weather, focus on changes in body temperature, and in high altitude areas, focus on blood oxygen saturation. Refer to medical research data and experimental results to clarify the specific relationship between weather factors and changes in physiological indicators. For example, in a high temperature environment, for every 1°C increase in body temperature, the heart rate may increase by 10-15 times / minute; for every 10% increase in humidity, the body's perceived temperature will increase by 1-2°C, thereby affecting the physiological state. In addition, consider that people of different ages, genders, and health conditions have different tolerance and reactions to the weather. The elderly, children, and people with chronic diseases such as cardiovascular disease are more sensitive to extreme weather, and the weight of the degree of impact needs to be adjusted according to the specific user situation during the evaluation.

[0075] In some embodiments, determining the impact of weather hazards on users' access to outdoor areas includes the following: grading common weather hazards by severity, such as rainstorms can be divided into general rainstorms, heavy rainstorms, and extremely heavy rainstorms; strong winds can be divided into level 3-4 breezes, level 5-6 strong winds, and level 7 and above gales, etc., and different levels have different impacts on outdoor activities. Analyze the impact of different weather conditions on users' outdoor activities such as walking, vision, and equipment use. For example, low visibility in foggy weather will severely limit users' vision and increase the risk of getting lost and colliding; heavy snow may cause deep snow on the road, making it difficult to walk or even impossible to move forward. Combined with historical data and meteorological models, the probability of dangerous events occurring in specific weather conditions is evaluated, such as the probability of lightning strikes caused by thunderstorms, the probability of floods caused by heavy rains, etc. The higher the probability, the greater the impact on users' access to outdoor areas.

[0076] In some embodiments, the evaluation of the degree of impact of geographical hazards on physiological monitoring items includes: clarifying the impact of different geographical hazard factors, such as high altitude, steep slopes, wetlands, deserts, etc. on physiological indicators.

[0077] Based on sports medicine and physiological research, we understand the stress response of the human body in different geographical environments. In the high temperature environment of the desert, the human body loses water quickly, which will cause blood concentration and blood pressure changes. In severe cases, it will lead to diseases such as heat stroke. The degree of impact can be evaluated based on the relationship between the amount of water loss and the change of physiological indicators. Considering the user's ability to adapt to a specific geographical environment, people who have lived in plains for a long time will have a stronger physiological reaction when they first arrive at a high altitude area than those who have lived in plateaus for a long time. Users with poor adaptability are more affected by geographical risks on physiological monitoring items.

[0078] In some embodiments, the evaluation of the degree of impact of geographical hazards on user access to outdoor areas includes: measuring terrain complexity through indicators including slope, elevation difference, and terrain undulation. Assess whether the geology is stable, such as whether there are hidden dangers such as landslides, mudslides, and ground collapse. Determine the possibility and degree of harm of geological disasters through geological survey reports, historical geological disaster records, etc. Unstable geology has a great impact on user access to outdoor areas. Special geographical environment obstacles: For special geographical environments such as wetlands, swamps, and jungles, analyze their obstacles to user passage, equipment carrying, navigation and positioning. Wetlands may cause feet to sink into the mud, increase walking resistance and physical exertion; it is easy to get lost in the jungle, and there may be threats from wild animals, all of which will seriously affect user access to outdoor areas.

[0079] When the user arrives at the predetermined outdoor area, the monitoring work will automatically start. In this process, the smart watch, as a common portable device for users, shares the responsibility of data collection with additional preset monitoring devices. Smart watches have certain basic monitoring functions, while preset monitoring devices are set up to obtain various types of data more comprehensively and accurately. They work together to meet the needs of users for all-round monitoring. Smart watches have built-in sensors such as heart rate sensors, accelerometers and gyroscopes. With the help of the built-in global positioning system (GPS) or other positioning technologies (such as the Beidou satellite navigation system), smart watches can accurately determine the user's geographic location, including longitude, latitude and altitude information. Although smart watches have certain physiological monitoring capabilities, they still have limitations in some cases. Preset monitoring devices worn on the body can provide more comprehensive and accurate physiological data. The data collected by the preset monitoring devices worn on the body need to be transmitted to the smart watch through wireless communication technology. After receiving data from different devices, the smart watch will integrate and process the 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, users can conveniently view their data on smart watches, and these data also provide a reliable basis for subsequent analysis and decision-making, so as to timely discover potential problems and take corresponding measures.

[0080] Step 105 is to analyze whether the physiological monitoring items are abnormal according to the physiological data, analyze whether the user encounters weather hazards according to the comprehensive environmental data, and analyze whether the user encounters geographical hazards according to the comprehensive location data and physiological data; if any one of the items is yes, take corresponding countermeasures.

[0081] Analyze whether the physiological monitoring items are abnormal based on physiological data. For each physiological monitoring item, there is a corresponding normal range, which can be personalized according to factors such as age, gender, and physical condition. The system will analyze the collected physiological data in real time or regularly, and compare the current physiological data with the set normal range and threshold. If the data of a physiological monitoring item exceeds the normal range and reaches the warning threshold, such as the heart rate suddenly rises to more than 130 beats / minute, or the body temperature exceeds 38°C, it can be determined that the physiological monitoring item is abnormal.

[0082] Comprehensive environmental data is used to analyze whether the user encounters a weather hazard. According to the weather hazard items and their characteristics determined in step 102, the current environmental data is matched with them. For example, if there is a "high temperature weather hazard" in the weather hazard items, and the high temperature threshold is set to 35°C, when the environmental data shows that the current temperature reaches or exceeds 35°C, it can be preliminarily determined that the user may have encountered a high temperature weather hazard. In addition to a single weather element data, the relationship and change trend of multiple environmental data must also be considered comprehensively. For example, when judging whether there is a precipitation weather hazard, it is necessary not only to pay attention to the rainfall, but also to consider the duration of the rainfall, changes in rainfall intensity, and weather conditions in the surrounding areas.

[0083] The location data and physiological data are combined to analyze whether the user encounters a geographical hazard. The location data is provided by the positioning function of the smart watch, including the user's latitude and longitude, altitude and other information. These location data are combined with the geographical information of the outdoor area obtained in step 102 (such as topography, geological conditions, water distribution, etc.) to determine the specific geographical environment in which the user is currently located. The user's physical state and activity can be understood by analyzing the user's physiological data. If the user's heart rate rises sharply and breathing becomes rapid in a short period of time, combined with the location data, it is found that the user is on a steep hillside, which may mean that the user's body is under a heavy load during the climbing process, and there is a risk of slipping, rolling down, and encountering terrain-related geographical hazards due to physical exhaustion; if the user is close to the water and has physiological and psychological reactions such as abnormal heart rate and panic, it may indicate that the user is at risk of drowning or other geographical hazards related to waters. Taking into account the location data and physiological data, a comprehensive judgment is made on whether the user encounters a geographical hazard. For example, when a user is in a geologically unstable area (such as an area where a landslide has occurred before) and the physiological data shows that the user is in poor physical condition (such as fatigue, decreased physical strength), the risk of encountering geological hazards such as landslides will increase. Through this comprehensive analysis, the risk of geographical hazards faced by users can be more accurately assessed and corresponding measures can be taken in a timely manner.

[0084] In this application, each abnormal physiological monitoring item, weather hazard item or geographical hazard item is pre-configured with a countermeasure. Once it is determined that the user's physiological monitoring item is abnormal, encounters any of the weather hazard items or geographical hazard items, the system will take corresponding actions according to the countermeasures pre-configured in step 103 for the specific situation. For example, if the physiological monitoring item is abnormal, such as a high heart rate, the countermeasure may be to remind the user to stop the activity, rest in place, and provide some simple relaxation and recovery suggestions; if it is a strong wind weather hazard, the countermeasure may be to suggest that the user find a sturdy building or other safe shelter to hide. The smart watch will convey the information of the countermeasures to the user through sound, vibration, screen prompts, 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 on his own, the smart watch can also automatically send a help message to the preset emergency contact or rescue agency, including the user's location, current abnormal situation, etc., so as to obtain external help and support in time.

[0085] For example, when the body temperature exceeds the normal range, the user is prompted to drink more warm water to replenish water and prevent dehydration. When the blood pressure is too low, the user is reminded to change the body position slowly to avoid standing up suddenly, which may cause dizziness or fainting. When the weather hazard is heavy rain, a safe indoor place can be found for the user in advance. If cracks are found on the ground or signs of looseness in the mountain, the user is prompted to quickly move away from the area and move to a place with higher terrain and stable geology.

[0086] In some specific embodiments, abnormal physiological parameter items corresponding to various weather hazard items and geographical hazard items are determined in advance, and the abnormal physiological parameter items are abnormal physiological parameters caused when encountering weather hazard items or geographical hazard items; when arriving at the outdoor area, the abnormal physiological parameter items corresponding to the weather hazard items and geographical hazard items in the outdoor area are monitored preferentially; when a physiological parameter of the user is abnormal, it is determined whether the abnormal physiological parameter is the abnormal physiological parameter item corresponding to the weather hazard item or 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 location data.

[0087] Identify the abnormal physiological parameters corresponding to each weather hazard and geographical hazard. Different weather conditions will have different effects on human physiology. Special geographical environments will also affect human physiological status. When the user arrives at the outdoor area, the system will give priority to monitoring the abnormal physiological parameters corresponding to the weather hazard and geographical hazard that may exist in the outdoor area. This is because these abnormal physiological parameters are closely related to the potential risks of the current outdoor environment. By giving priority to these parameters, the dangers that the user may face can be discovered more promptly. Compare the current abnormal physiological parameters with the abnormal physiological parameters corresponding to the predetermined weather hazard and geographical hazard. If it is determined that the abnormal physiological parameters may be related to weather hazards, 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 rises abnormally and the ambient temperature exceeds 35°C and the humidity is high, it is more likely to be a physiological reaction caused by high temperature weather, so it is judged that the user may have encountered a high temperature weather hazard. When it is suspected that the abnormal physiological parameters are related to geographical hazards, the system will make a judgment based on the user's location data (such as latitude and longitude, altitude, terrain, etc.). For example, if the user's blood oxygen saturation decreases and the location data shows that the user is at a high altitude, it can be determined that the user may have encountered a geographical hazard such as high altitude.

[0088] In some specific embodiments, map data, geological data, route data and historical area data of an outdoor area are obtained; areas involving safety hazards are screened out from the historical area data to obtain historical hazard areas, and the currently marked hazard areas in the outdoor area are used as first hazard areas; in combination with weather information of the outdoor area, areas that may have safety hazards within a preset time period are determined based on geological data to obtain geological hazard areas; historical hazard areas, first hazard areas and geological hazard areas are marked in the map data to determine geographical hazard items, and path planning is performed in combination with route data to plan a movement route that avoids hazard areas.

[0089] Obtain detailed map data of outdoor areas, including topography, road distribution, building location, water distribution and other information. These data can be obtained through channels such as geographic information systems (GIS), satellite remote sensing images, and professional mapping agencies. Geological data contains information such as geological structure, rock type, soil properties, and groundwater level in outdoor areas. These data are usually collected and analyzed by geological exploration departments, scientific research institutions, etc. Route data records the route information of existing roads, trails, and trails in outdoor areas, including the length, direction, slope, and traffic conditions of the routes. 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 are more suitable for cycling. 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 that have occurred (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, and other channels.

[0090] Areas involving safety hazards are screened out from historical regional data. These areas may be places where disasters or accidents have occurred in the past, or areas known to have potential hazards. For example, hillside areas where landslides have occurred, low-lying areas prone to floods, etc., are identified as historical hazard areas. The currently marked hazard areas in the outdoor area are used as the first hazard areas. These marked hazard areas may be determined by on-site investigations, signs and identification, such as setting warning signs on the edge of dangerous cliffs, or marking areas where dangers may exist. Combined with the weather information of the outdoor area, the areas that may have safety hazards within the preset period are determined according to geological data. For example, if the current weather information shows that there will be a lot of rainfall in the near future, and the geological data shows that the soil in the area is relatively soft and the geological structure is unstable, it can be inferred that geological disasters such as landslides and mudslides may occur in the area within the preset period, thereby identifying these areas that may have safety hazards as geological hazard areas. The historical hazard areas, the first hazard areas, and the geological hazard areas are marked in the map data. By marking on the map, various safety hazard areas in the outdoor area can be intuitively displayed. These marked hidden danger areas constitute geographical hidden danger items. Users can clearly understand which areas have potential dangers by viewing the map. Combined with route data, path planning is carried out according to the marked hidden danger areas. The goal of planning is to avoid these hidden danger areas and plan a relatively safe movement route for users. For example, if a route passes through a historical hidden danger area or a geological hidden danger area, then when planning the path, the area will be bypassed and other relatively safe routes will be selected. When planning a path, factors such as the length, difficulty, and traffic conditions of the route can also be considered to ensure that the planned route is both safe and suitable for the user's actual situation.

[0091] In some specific embodiments, when planning a path, it is determined whether a mobile route that avoids the historical hazard area, the first hazard area, and the geological hazard area can be planned: if so, it is determined that the user is currently suitable for visiting the outdoor area; if not, the risk factor of the historical hazard area is evaluated; when the risk factor is in a preset safety interval, after it is determined that a mobile route that avoids the first hazard area and the geological hazard area can be planned, it is determined that the user is currently suitable for visiting the outdoor area; if the risk factor is not in the preset safety interval, it is determined that the user is currently not suitable for visiting the outdoor area. The safety interval is set according to the risk factor. The principle is as shown in the attached figure. Figure 4 shown.

[0092] When planning routes for users to visit outdoor areas, the primary goal is to completely avoid historical hazard areas, first hazard areas, and geological hazard areas. These hazard areas include areas where dangerous events have occurred in the past (historical hazard areas), areas that are currently clearly marked as dangerous (first hazard areas), and areas that may be dangerous during a preset period of time based on geological data and current weather forecasts (geological hazard areas). If a mobile route that does not pass through these hazard areas can be successfully planned, it means that the user can avoid known and potential dangers with a high probability when moving in the outdoor area, so it can be determined that the user is currently suitable to visit the outdoor area.

[0093] When it is impossible to plan a movement route that completely avoids these three types of hazard areas, the next step of assessment is required. First, assess the risk factor of the historical hazard area, which 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, in an area where a landslide has occurred, if the geological conditions in the area have not improved significantly in the near future and there are signs of another landslide, then its risk factor will be higher; conversely, if the risk level is reduced after governance, the risk factor will also be reduced accordingly.

[0094] The safety interval is set according to the evaluation criteria of the risk factor and is a safe range. When the risk factor is in the safety interval, the historical hazard area in the area is relatively safe, and it can be analyzed whether a movement route that avoids the first hazard area and the geological hazard area can be planned. If the risk factor of the historical hazard area is not in the preset safety interval, it means that even if the user only passes through the historical hazard area, he or she faces a higher risk. The preset safety interval is a limit value set based on past experience, safety standards, etc., which is used to measure whether the degree of danger is acceptable.

[0095] Similarly, if it is impossible to plan a route that avoids the first hazard zone and the geological hazard zone, it means that it is difficult for users to avoid contact with dangerous areas when they are in the outdoor area, and it is not suitable to visit. For example, a historical hazard area has suffered severe flood disasters many times, and the current risk factor is higher than the preset safety factor, or the route cannot be planned to avoid the first hazard zone and the geological hazard zone. In this case, users may encounter danger when going to the outdoor area, so it is not suitable to visit.
