Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an early warning method and electronic equipment. Background Art

[0002] With the improvement of living standards, more and more people like diving. However, due to the openness of diving waters, large water areas, and the impact of climate change, even if the diving routes are designated in advance, there will be some diving areas with potential safety hazards, and divers are prone to danger when diving in such diving areas.

[0003] In the related art, the smart rescue bracelet device in water areas can release the life-saving device in dangerous situations. However, this method cannot prevent divers from entering dangerous diving areas. Summary of the invention

[0004] The present application provides an early warning method and electronic equipment, which can remind divers to leave the current water area when the diving water area is abnormal, so as to prevent divers from entering dangerous diving areas.

[0005] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0006] In a first aspect, the present application provides an early warning method, which includes: obtaining first data; the first data includes a change value of a first parameter per unit time; the first parameter includes a pressure value, a diving depth, and a user movement speed; judging whether the diving water area is abnormal based on the first data, and issuing an early warning prompt when the diving water area is abnormal.

[0007] In this way, divers (users) can be reminded to leave the current waters before entering dangerous waters. And judging whether the diving waters are abnormal is based on the change values ​​of multiple parameters in a unit time, not just based on the instantaneous values ​​of multiple parameters. The judgment result obtained by the method of the embodiment of the present application is more accurate.

[0008] In a possible implementation, the method further includes: obtaining heart rate data; and providing an early warning according to the first data and the heart rate data. In this way, whether the diving water area is abnormal can be determined according to the change of the user's heart rate data, and the obtained determination result is more accurate.

[0009] In one possible implementation, the pressure is associated with the diving attitude.

[0010] Exemplarily, when the diving posture is forward diving, the pressure value received by the smart bracelet increases.

[0011] In a possible implementation, issuing an early warning prompt based on the first data includes: calculating the second data based on the first data; issuing an early warning prompt based on the second data, the change value of the user's movement speed per unit time, and the change value of the pressure difference per unit time.

[0012] Optionally, the second data is a constant. When the diver dives, the smart bracelet obtains the change value of the user's movement speed per unit time and the change value of the pressure difference per unit time, and determines whether the diving water area is abnormal based on the second data, the change value of the user's movement speed per unit time and the change value of the pressure difference per unit time. When the diving water area is abnormal, an early warning prompt is issued.

[0013] In a possible implementation, an early warning is given based on the second data, the change value of the user's movement speed within a unit time, and the change value of the pressure difference within a unit time, including: when the change value of the pressure difference within a unit time is greater than a first threshold value and / or the pressure value within a unit time is greater than a second threshold value, an early warning is given. In this way, whether the diving water area is abnormal can be judged based on the change in the pressure value, and the judgment result obtained is more accurate.

[0014] For example, when the pressure value continues to increase over a period of time and the change in the pressure difference per unit time is greater than a first threshold, the diving water area may be abnormal and an early warning prompt is required.

[0015] As another example, when the pressure value suddenly increases within a period of time and the pressure value per unit time is greater than the second threshold, the diving water area may be abnormal and an early warning prompt is required.

[0016] In a possible implementation, issuing an early warning prompt based on the first data and the heart rate data includes issuing an early warning prompt when the change value of the heart rate data per unit time is greater than a third threshold value and / or the heart rate data per unit time is greater than a fourth threshold value. In this way, judging whether the diving water area is abnormal based on the change of the user's heart rate data, the judgment result obtained is more accurate.

[0017] For example, when the heart rate data continues to increase over a period of time and the change value of the heart rate data per unit time is greater than a first threshold, the diving water area may be abnormal and an early warning prompt is required.

[0018] As another example, when the heart rate data suddenly increases within a period of time and the heart rate data per unit time is greater than a second threshold, the diving water area may be abnormal and an early warning prompt is required.

[0019] In a possible implementation, the second data is calculated based on the first data, including: when the pressure value of the first depth of the diving water area is the first value, the second data is the second value; when the pressure value of the first depth of the diving water area is the third value, the second data is the fourth value; the first value is different from the third value; the second value is different from the fourth value. In this way, the second data of different diving water areas are different, which further improves the accuracy of the judgment result.

[0020] In a possible implementation, the diving posture includes at least one of: paddling forward, paddling backward, paddling upward, paddling downward, and being still.

[0021] In a possible implementation, the warning prompt includes at least one of a vibration reminder, a ringtone reminder, a voice reminder, and a text reminder.

[0022] In the second aspect, the present application provides an early warning device, including: an acquisition module: used to obtain first data; the first data includes a change value of a first parameter per unit time; the first parameter includes a pressure value, a diving depth, and a user movement speed; a processing module, used to issue an early warning prompt based on the first data.

[0023] In a third aspect, the present application provides a computer-readable storage medium, which includes a computer program or instructions. When the computer program or instructions are executed on a business processing device, the business processing device executes the method described in the first aspect.

[0024] In a fourth aspect, the present application provides a chip system comprising at least one processor and at least one interface circuit, wherein the at least one interface circuit is used to perform transceiver functions and send instructions to at least one processor, and when the at least one processor executes the instructions, the at least one processor executes a method as described in any one of the above-mentioned first aspects.

[0025] In a fifth aspect, the present application also provides a computer program product, comprising instructions, which, when executed on a computer, enables the computer to execute the method as described in any one of the first aspects.

[0026] In a sixth aspect, an embodiment of the present application provides a circuit system, the circuit system includes a processing circuit, and the processing circuit is configured to execute the method of the first aspect or any one of the implementations of the first aspect.

[0027] In the seventh aspect, an embodiment of the present application provides an electronic device, comprising: a processor and a memory, the memory being coupled to the processor, the memory being used to store computer program code, the computer program code comprising computer instructions, and when the processor reads the computer instructions from the memory, the electronic device executes the method of the first aspect or any one of the implementations of the first aspect.

[0036] The terms "including" and "having" and any variations thereof mentioned in the description of the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0055] like Figure 3 As shown, it is a structural schematic diagram of the early warning system of an embodiment of the present application, and the early warning system includes an electrocardiogram (ECG) heart rate data measurement module 301, a pressure sensor module 302, a barometer module 303, a gyroscope module 304, a positioning module 305, a data fusion module 306 and an early warning prompt module 307.

[0056] The ECG heart rate data measurement module 301 is used to measure the heart rate data of the diver and send the heart rate data to the data fusion module 306 .

[0057] The pressure sensor module 302 is used to measure the pressure data of the electronic device and send the pressure data to the data fusion module 306 .

[0058] The barometer module 303 is used to measure the diving depth data of the diver and send the diving depth data to the data fusion module 306 .

[0059] The gyroscope module 304 is used to determine the diving posture information of the diver and send the diving posture information to the data fusion module 306 .

[0060] The positioning module 305 is used to determine the location information of the diver and send the location information to the data fusion module 306. Optionally, the positioning module 305 can be positioned by the global positioning system (GPS) or the Beidou navigation satellite system (BDS). The positioning module 305 can also be positioned by other positioning systems, which is not specifically limited in the embodiment of the present application.

[0061] Optionally, the embodiment of the present application may be introduced by taking the positioning module 305 positioning by GPS as an example.

[0062] The data fusion module 306 is used to receive the heart rate data from the ECG heart rate data measurement module 301, the pressure data from the pressure sensor module 302, the diving depth data from the barometer module 303, the diving posture information from the gyroscope module 304, and the position information from the positioning module 305, and perform calculations based on this information to determine whether the current diving water area is abnormal. The data fusion module 306 is also used to send the judgment result to the early warning prompt module 307.

[0063] The early warning module 307 is used to receive the judgment result from the data fusion module 306 and issue an early warning signal according to the judgment result.

[0064] Optionally, before diving, the diver checks the smart bracelet to ensure that the ECG heart rate data measurement module 301, the pressure sensor module 302, the barometer module 303, the gyroscope module 304, the positioning module 305, the data fusion module 306 and the early warning prompt module 307 are operating normally.

[0065] Optionally, the embodiment of the present application is introduced by taking the electronic device as a smart bracelet as an example.

[0066] The specific process of the embodiment of the present application is described in detail as follows. Figure 4 FIG. 1 is a flowchart of an early warning method provided in an embodiment of the present application, the method comprising steps S101-S102:

[0067] S101. The smart bracelet obtains first data.

[0068] Optionally, the first data includes a change value of the first parameter per unit time; the first parameter includes user heart rate data, pressure, diving depth, diving posture, user movement speed (diving speed), etc.

[0069] Optionally, the first data includes heart rate data change data of the diver per unit time, pressure change data per unit time, diving depth, diving posture, and movement speed of the diver.

[0070] Optionally, the smart bracelet can measure the diver's heart rate data through an ECG heart rate data module. Exemplarily, within 1 minute, the diver's heart rate data varies between 70bpm and 85bpm.

[0071] Optionally, when the diver's heart rate data continues to increase for a period of time, the current diving waters may be abnormal and the diver may be entering dangerous waters. For example, when the diver's heart rate data changes between 70bpm-85bpm in the first minute, and the diver's heart rate data changes between 85bpm-120bpm in the second minute, and the diving speed does not change, the current diving waters may be abnormal and the diver may be entering dangerous waters.

[0072] Optionally, the smart bracelet can measure the pressure value through a pressure sensor. Exemplarily, within 1 minute, the pressure value changes between 30kPa-60kPa.

[0073] Optionally, when the pressure value continues to increase over a period of time, the current diving waters may be abnormal and the diver may be entering dangerous waters. For example, when the pressure value changes between 30kPa-60kPa in the first minute and between 60kPa-120kPa in the second minute, and the diving depth does not change, the current diving waters may be abnormal and the diver may be entering dangerous waters.

[0074] Optionally, the smart bracelet can determine the diving posture through a gyroscope. The diving posture may include forward paddling, backward paddling, upward paddling, downward paddling, stillness, and the like.

[0075] Optionally, the diving posture has a certain influence on the pressure value. Optionally, the pressure sensor can be Figure 1 At the position of the screen shown, when the arm moves forward, the pressure value detected by the pressure sensor increases, and when the arm moves backward, the pressure value detected by the pressure sensor decreases.

[0076] For example, when the diver paddles forward, the pressure value will increase, for example, increase to 60 kPa. Although the pressure value is relatively large at this time, the increase in pressure value is caused by the diver paddling forward, which is a normal phenomenon and the diving environment is safe.

[0077] As another example, when the diver paddles downward, the diving depth increases and the pressure value increases, for example, increases to 80 kPa. Although the pressure value is relatively large at this time, the increase in pressure value is caused by the diver paddling downward, which is a normal phenomenon and the diving environment is safe.

[0078] Optionally, the smart bracelet can determine the diving depth through a barometer. Exemplarily, the current diving depth is 8 meters.

[0079] Optionally, the safety pressure value ranges corresponding to different diving depths are different. For example, when the diving depth is 8 meters, the safety pressure value range is between 30kPa-60kPa. When the diving depth is 20 meters, the safety pressure value range is between 180kPa-250kPa.

[0080] Optionally, the smart bracelet can determine the diving speed through GPS. Specifically, the smart bracelet can calculate the diving speed based on the position of the previous minute and the current position. For example, if the distance between the position of the previous minute and the current position is 10m, the diving speed is 10m / min.

[0081] S102: The smart bracelet issues an early warning prompt based on the first data.

[0082] Optionally, the smart bracelet can calculate the second data based on the first data of the safety data, and then issue an early warning prompt based on the second data and the first data collected by the smart bracelet during diving.

[0083] Optionally, the pressure value and speed of the safe diving water area within a period of time may be detected first, and the pressure value and speed satisfy formula (1):

[0084]

[0085] Among them, F0 is the current pressure value detected by the smart watch, ΔF is the pressure difference within Δt time, t represents the diving time, δ represents the viscosity coefficient of the current water area, h represents the diving depth, V0 represents the diving speed, and a represents the diving acceleration. Optionally, according to formula (1), formula (2) can be simplified to:

[0086]

[0087] Wherein, k0 is a constant and H0 is a constant. When formula (2) is greater than 0, it means that the current diving water area is abnormal and the diver may be entering dangerous waters. An early warning is required to remind the diver to leave the current water area.

[0088] Optionally, formula (2) can be simplified to obtain formula (3):

[0089]

[0090] Wherein, k (second data) is a constant. When formula (3) is greater than 0, it indicates that the current diving water area is abnormal and the diver may be entering dangerous waters. An early warning is required to remind the diver to leave the current water area. When formula (3) is less than 0, it indicates that the current diving water area is a safe water area.

[0091] Optionally, when a diver is diving, the smart bracelet can detect the diving speed and pressure value over a period of time, and bring them into the above formula (3). When formula (3) is greater than 0, it means that the current diving water area is abnormal, and the diver may be entering dangerous waters. An early warning prompt is required to remind the diver to leave the current water area.

[0092] Optionally, when the pressure at the first depth of the diving water area is a first value, the second data k is a second value; when the pressure at the first depth of the diving water area is a third value, the second data k is a fourth value. That is, the k values ​​of different diving water areas may be different.

[0093] For example, when the diving water area is sea water, the pressure value detected by the smart bracelet when the diving water area is 8m is 60kPa, and the second data k is k1; when the diving water area is fresh water, the pressure value detected by the smart bracelet when the diving water area is 8m is 50kPa, and the second data k is k2; k1 is different from k2.

[0094] Optionally, when the diver's speed and pressure difference continue to increase over a period of time, and the speed increase rate does not match the pressure difference increase rate, the current diving waters may be abnormal, the diver may be entering dangerous waters, and f0 is greater than 0.

[0095] Optionally, under normal circumstances, the diving speed increases slowly, that is, the diving acceleration is small. Therefore, when the change in pressure difference per unit time is greater than the first threshold and / or the pressure value per unit time is greater than the second threshold, the current diving water area may be abnormal, the diver may be entering dangerous waters, and f0 is greater than 0.

[0096] Exemplarily, the first threshold value may be 80 kPa, the initial speed of the diver is 2 km / h, the pressure value is 50 kPa, the diving depth is 8 m, and then the diver accelerates downward, and the speed after one minute is 2.5 km / h, the pressure value is 180 kPa, and the diving depth is 14 m. Among them, the pressure difference is 180-50=120 kPa. At this time, relative to the change in the speed and diving depth of the diver, the pressure difference under normal circumstances is generally 80 kPa. However, the increase in the diver's pressure difference is greater than the first threshold value, the current diving waters may be abnormal, and the diver may be entering dangerous waters, and f0 is greater than 0.

[0097] For another example, the first threshold may be 220 kPa, the diver's initial speed is 2 km / h, the pressure value is 50 kPa, the diving depth is 8 m, and then the diver accelerates downward, and after one minute the speed is 2.5 km / h, the pressure value is 180 kPa, and the diving depth is 14 m. In one minute, the pressure value rises to 250 kPa, which is greater than the second threshold. The current diving waters may be abnormal, and the diver may be entering dangerous waters, and f0 is greater than 0.

[0098] In one embodiment, the smart bracelet can also obtain the user's heart rate data and issue an early warning prompt based on the first data and the heart rate data.

[0099] Optionally, when the diver's speed, heart rate data, and pressure difference continue to increase over a period of time, and the speed increase rate does not match the heart rate data and pressure difference increase rate, the current diving waters may be abnormal, the diver may be entering dangerous waters, and f0 is greater than 0.

[0100] For example, the diver's initial speed is 2km / h, the pressure value is 50kPa, the heart rate data is 70bpm, and the diving depth is 8m. Then the diver accelerates downward, and one minute later the speed is 2.5km / h, the pressure value is 180kPa, the heart rate data is 130bpm, and the diving depth is 14m. Among them, the pressure difference is 180-50=120kPa, and the heart rate data increases by 130-70=60bpm. At this time, relative to the changes in the diver's speed and diving depth, the pressure difference under normal circumstances is generally 80kPa, and the heart rate data generally increases by 30bpm. However, the increase in the diver's pressure difference and heart rate data is higher than normal. The current diving waters may be abnormal, and the diver may be entering dangerous waters, and f0 is greater than 0.

[0101] Optionally, when the diver's speed and heart rate data continue to increase over a period of time and the pressure difference remains unchanged, the current diving waters may be abnormal, the diver may be entering dangerous waters, and f0 is greater than 0.

[0102] Optionally, under normal circumstances, the diving speed increases slowly, that is, the diving acceleration is small. Therefore, when the change in the heart rate data per unit time is greater than the third threshold and / or the heart rate data per unit time is greater than the fourth threshold, the current diving waters may be abnormal, the diver may be entering dangerous waters, and f0 is greater than 0.

[0103] For example, the third threshold is 30bpm, the diver's initial speed is 2km / h, the pressure value is 50kPa, the heart rate data is 70bpm, the diving depth is 8m, and then the diver accelerates to the horizontal. One minute later, the speed is 2.5km / h, the pressure value is 50kPa, the heart rate data is 120bpm, and the diving depth is 8m. Among them, the speed increased by 0.5km / h, and the heart rate data increased by 120-70=50bpm. At this time, relative to the change in the speed of the diver's increase, the heart rate data under normal circumstances generally increases by 30bpm. However, the increase in the diver's heart rate data is greater than the third threshold, the current diving waters may be abnormal, and the diver may be entering dangerous waters, and f0 is greater than 0.

[0104] For another example, the fourth threshold is 120bpm, the diver's initial speed is 2km / h, the pressure value is 50kPa, the heart rate data is 70bpm, and the diving depth is 8m. He then accelerates to dive forward horizontally. One minute later, the speed is 2.5km / h, the pressure value is 50kPa, and the heart rate data is 100bpm. During one minute, the heart rate data fluctuates greatly and rises to 150bpm, which is greater than the fourth threshold. The current diving waters may be abnormal, and the diver may be entering dangerous waters. f0 is greater than 0.

[0105] Optionally, when the pressure difference and heart rate data of the diver continue to increase over a period of time without changing speed, the current diving water area may be abnormal, the diver may be entering dangerous waters, and f0 is greater than 0.

[0106] For example, the diver's initial speed is 2km / h, the pressure value is 50kPa, the heart rate data is 70bpm, and the diving depth is 8m. Then he dives horizontally. One minute later, the speed is 2km / h, the pressure value is 120kPa, the heart rate data is 120bpm, and the diving depth is 8m. Among them, the pressure difference is 120-50=70kPa, and the heart rate data increases by 120-70=50bpm. At this time, relative to the increase in the diver's exercise time, the pressure difference under normal circumstances is generally unchanged, and the heart rate data generally increases by 30bpm. However, the increase in the diver's pressure difference and heart rate data is higher than normal. The current diving waters may be abnormal, and the diver may be entering dangerous waters, and f0 is greater than 0.
