In an embodiment, the state monitoring module 1 of the present invention includes a pressure monitoring module, an attitude sensing monitoring module, a heart rate monitoring module, a blood oxygen monitoring module, and a positioning monitoring module.

The pressure monitoring module is a pressure sensor which can accurately measure the atmospheric pressure value and the pressure value in water with the accuracy reaching a meter level. The pressure sensor can monitor the height of a user in real time through calculation of atmospheric pressure and the height, and can also monitor the water depth of the user in real time through calculation of water pressure and water depth, wherein the data acquisition rate is 80Hz-100 Hz.

In an embodiment, the attitude sensing monitoring module comprises a six-axis MEMS accelerometer and a gyroscope sensor, and the six-axis MEMS accelerometer and the gyroscope sensor can monitor acceleration data and gyroscope data in three mutually perpendicular directions of a three-dimensional space.

In an embodiment, the heart rate monitoring module of the present invention is an optical heart rate sensor. The optical heart rate sensor uses electro-optical solvent pulse wave graphy (PPG) to measure heart rate.

In an embodiment, the blood oxygen monitoring module is an optical blood oxygen sensor. The optical blood oxygen sensor irradiates red light and infrared light to the skin, then obtains the red light and the infrared light reflected by blood vessels under the skin, and finally calculates the blood oxygen through an algorithm. Whether the human body is healthy or not is judged by measuring the arterial oxygen saturation of the human body. The blood oxygen saturation specifically refers to the content ratio of hemoglobin combined with oxygen in blood, i.e., the concentration of blood oxygen in blood. Generally, a blood oxygen saturation level of 94% or less is considered as oxygen deficiency. If the condition of insufficient oxygen supply is caused, the normal metabolism of cells is directly influenced, and the life is threatened in serious cases, so the blood oxygen detection is very important.

The positioning monitoring module comprises a GPS positioning chip or a Beidou positioning chip. The positioning monitoring module is a high-precision radio navigation positioning system which can provide accurate geographic position, speed and precise time information anywhere in the world and in the near-earth space.

The judgment and early warning algorithm module 2 comprises a circuit board distributed with circuits and a microprocessor arranged on the circuit board, wherein an early warning judgment system is arranged in the microprocessor, and the microprocessor has a running processing function. The data transmission and storage module 3 is also mounted on the same circuit board as the microprocessor.

In use of the present invention, as shown in fig. 2, the user may use the user interaction system 5 to reset the data reference values stored in the microprocessor via the wireless bluetooth data transmission module, and may modify the pressure sensor threshold, blood oxygen depth threshold, heartbeat threshold and posture threshold, as well as the location information and alarm data. A safe distance prompt can be set through the APP at the mobile phone end, and meanwhile data stored in the data storage module can also be read.

The microprocessor can acquire monitoring data acquired by the six-axis MEMS accelerometer and the gyroscope sensor through a series of operation processing to acquire dynamic conditions and attitude information of a user, wherein the attitude information comprises a pitch angle, a roll angle and a yaw angle of the user, and the pitch angle, the roll angle and the yaw angle are respectivelyGround coordinate system Ox_iy_iz_iThree euler angles, which may indicate the use of relatively static pose information. The dynamic information is the instantaneous angular velocity of the user, also in the ground coordinate system Ox_iy_iz_iAngular velocities in three directions, which represent the relative dynamics of the user.

When the device is used, the pressure monitoring module, the posture sensing monitoring module, the heart rate monitoring module, the blood oxygen monitoring module and the positioning monitoring module monitor a user in real time, monitoring signals obtained by monitoring are transmitted to the microprocessor, and the microprocessor judges and processes received signals to obtain the safety condition of the user.

When the user is walking or is on the way of traveling, the accident falls and falls down, and user's dynamic gesture in the twinkling of an eye can make gesture sensing monitoring module's gyroscope data produce huge change this moment, and gyroscope threshold value when exceeding normal walking travel state promptly catches the unusual change of gyroscope data this moment when early warning judgement system, just judges immediately and handles and send out the police dispatch newspaper.

When a user is in outdoor activities, abnormal states are caused by accidents, for example, the user can not move due to discomfort and lying down on the ground, the posture monitoring data of the user in a relatively static state is greatly different from the normal condition data, and the early warning judgment system processes and gives an alarm.

When the user moves in outdoor plateau area, the human oxygen deficiency easily, but oneself can not notice, measures human artery oxyhemoglobin saturation through optical blood oxygen sensor and judges whether healthy, if oxyhemoglobin saturation is below 94%, will regard as the oxygen suppliment insufficient, directly influence the normal metabolism of cell, can threaten the life when serious, and early warning judgement system handles and sends out the signal this moment.

When a user climbs or slides outdoors, the user accidentally falls or slides in a severe environment to cause sudden falling, the monitoring device on the market cannot measure the height state of the user, the high sampling rate of the pressure sensor can immediately acquire the abnormal instantaneous change, and the early warning judgment system immediately processes the abnormal instantaneous change according to the data and sends out a warning signal. The invention is characterized in that the judgment is mainly carried out by the pressure sensor. Other markets generally adopt an attitude sensor as a main judgment part.

When the user moves in water, the underwater early warning device can not sink underwater under the general condition, when an accident occurs, the underwater early warning device sinks underwater for a certain depth, the pressure sensor monitors that the pressure value exceeds the normal water depth threshold value, and the early warning judgment system processes and sends an alarm at the moment.

When the user is in water, when taking place drowning, because amazing people's sympathetic nervous system, the alert system of brain especially will arouse stress response reflexively, the heartbeat is accelerated, and the heart also can compensatory quickening rhythm of the heart in the oxygen deficiency prophase, and optical heart rate sensor monitoring rhythm of the heart data is unusual too fast this moment, and early warning judgement system handles and sends out the alarm this moment.

When the user appears drowned, can try the upset of lying on the back (drowned person can instinctively want to come back to look for the day, just so can have the respiratory leeway of opening), because under the normal condition, the gesture of lying on the back can not appear in water, gesture sensing monitoring module monitoring user gesture this moment appears unusually, and early warning judgement system handles and sends out the police dispatch newspaper at once.

When the user is drowned, because sympathetic nerve receives the stimulation, the user reflexively arouses the overstimulation reaction, can incessantly struggle or struggle to a direction, and the user is in a developments and irregular state this moment, and gesture sensing monitoring module can monitor out irregular dynamic data change and mixed and disorderly gesture angle this moment, and early warning judgement system handles and sends out the police dispatch newspaper at once.

While the preferred embodiments of the present invention have been illustrated, various changes and modifications may be made by one skilled in the art without departing from the scope of the invention.
