The prerequisite is that the regional time is not the preset sleep time, the signal of the sensing component (2) system is received, and the wrist is detected by the sense body (1 0 ) or the buckle (9). The table (丨) is in the wearing condition, and the part of the wrist acceleration (4 2 ) is mainly measured. The formula is as follows: AM = fl+a2y+^f where ' ax, ay, az are the three-axis acceleration sensing of the watch respectively. The acceleration of the three vertical directions collected by the device (2 3 ). The acceleration of the boat requires information on the magnitude and direction, because the body acceleration (4 1 ) will produce a large number of value changes when the fall occurs. (fifth figure) 'The body posture after the fall will be or approximate the inverted posture, and the reconnaissance posture needs to be judged by the direction of the lying acceleration (4 1 ), so the present invention adopts the custom parameter | AC | The magnitude and direction of acceleration are used to make a fall test. I The characteristics of AC | are observed in the fifth figure. It is impossible to know from the am that the posture change of the body (the standing position and the inverted posture are all values 1), and the value change related to the posture change needs to be seen by 丨AC | When the body falls down, its value is 1, 200912814 is different from standing when its value is equal to 〇, I AC I is calculated as follows: μ + Ι α is called = _sine, where 3 is the current body acceleration vector (by the sensing element ( 2) Instant measurement); b is the body acceleration vector when standing (measured by the sensing element (2) after standing or standing upright; θ is the refresh angle of 8 and b). After parameterization, the process of fall reconnaissance can follow the discriminant rule of the fourth figure. If the magnitude of the body acceleration (4丨) is higher than the fall threshold (4 3 ), it will start 2 seconds after the detection exceeds the threshold event. Posture reconnaissance (44), if confirmed as a lying position (45), an alarm (46) will be issued. The alarm (46) is issued by the watch (1) system, and the sound source output (7) can send a distress sound and simultaneously by the wrist. The wireless module (25) notifies the relevant care unit and personnel. If the alarm (46) is a false positive, the user can also cancel the wrong alarm by pressing the cancel button (47) (4 8). The reconnaissance process suspected of being in a coma state can be seen in the fourth picture, and the wrist acceleration (42) and the body acceleration (4) are simultaneously coordinated to detect, and (4) the two same characteristics are used for the wrist and the body respectively. Set the inter-activity value "9 and 5°)' if the wrist acceleration ((2) and body acceleration 41) are lower than the wrist and body activity thresholds (49 and 50) continue to exceed the watch (1) and then = between )) At the time, the user has the wearer and the area time is a low-prevention activity when the non-preset sleep is absent. If the user has the action as the alarm (46 body or body responds, the alarm is cancelled (48), If the second report, "block judgment, the user can cancel the wrong report by pressing the cancel button (47). 200912814 The present invention has a device for storing (5 4 ) (. 4th) and The mechanism, wrist acceleration (4 2 ) and body acceleration (4 1 ) will be recorded in accordance with the regional time, and the user's activity daily accumulation, weekly accumulation, monthly accumulation, annual accumulation, etc. can be transmitted through the display interface ( 5) to know, and store in the watch (1) (5 4 ) Set as flash memory, based on portability and size considerations, using a micro-SD card as a recommended device, the memory card can be taken out and transmitted to a personal or hospital computer (5 6 ), convenient for users and related The health care provider keeps track of the user's activity for a long time to make appropriate exercise program adjustments. When the accumulated activity is lower than the specific level, the watch (1) system can also be set and displayed on the display interface (5). The warning sign is used as a reminder. In addition, in case of a misjudgment causing the user to press the cancel button (4 7 ), the misjudgment record is also recorded in the flash memory, and the misjudgment record includes the area time and the current acceleration for convenience. The development and maintenance personnel of the present invention continue to improve the system.
