and step S41, in the dormant state, judging whether the wrist strap medical equipment is currently in the wearing state according to the acquired real-time wearing pressure data.
In the embodiment of the invention, the dormant state is a state when the wrist strap medical device is not normally operated after being started. Wear pressure data in real time set up in the wrist strap detects the real-time pressure data of wrist to wrist strap medical equipment with the pressure sensor of wrist contact one side, and when not wearing, real-time wearing pressure data is zero, and when wearing, the wrist fits with wrist strap medical equipment's wrist strap, and pressure sensor acquires real-time wearing pressure data.

And step S42, if the wrist strap medical equipment is currently in a wearing state, prompting correct wearing direction and identification action.
In the embodiment of the invention, the recognition action is that the wrist band medical equipment is preset to recognize the action of wearing the wrist band medical equipment on the left hand or the right hand, for example, the hands naturally vertically face downwards at the beginning, and then the hands wearing the wrist band medical equipment are slowly lifted until the wrist band medical equipment is parallel to the ground.

In an embodiment of the invention, the inertial data is data acquired by a user imitating an inertial measurement unit of the wrist band medical device during the recognition action, and the inertial data comprises three-axis components of acceleration, angular velocity and magnetic field. The wrist band medical equipment acquires inertia data imitating the identification action process through an inertia measurement unit.

and acquiring an updated quaternion through a comparison algorithm according to the variation of the quaternion.
And a substep S432 of projecting the triaxial acceleration component into a geographic coordinate system through the quaternion.
The geographic coordinate system is a coordinate system established by taking the reference ellipsoid as a datum plane, the center of the earth is taken as a coordinate origin, and an x axis, a y axis and a z axis of the geographic coordinate system respectively point to the east-north-sky direction. And converting the triaxial acceleration components into a geographic coordinate system, wherein the conversion formula is as follows:
wherein, the left array n is the acceleration triaxial component projection under the geographic coordinate system, the right array b is the acceleration triaxial component projection under the carrier coordinate system,

And step S44, acquiring the motion characteristics of the current wearing hand according to the acceleration, and further identifying the current wearing hand as a left hand or a right hand.
In an embodiment of the invention, the currently worn hand is the hand of the currently wristband medical device. The motion characteristics are the changes of the direction of the current wearing hand motion obtained by angular velocity in the process of simulating the recognition action in the geographic coordinate system. Specifically, step S44 includes:
a substep S441, obtaining a plurality of motion direction changes of the current wearing hand in the geographic coordinate system according to the acceleration;
if the recognition action is that the two hands naturally vertically face downwards when the recognition action is started, then the hand wearing the wrist strap medical equipment is slowly lifted until the end of the recognition action is parallel to the ground, then when the current hand wearing is vertical to the ground, the y-axis motion direction is obtained, and when the arm is parallel to the ground and the thumb of the hand is at the top, the x positive axis direction is obtained as the motion direction.
And a substep S442 of identifying the current wearing hand as a left hand or a right hand according to the plurality of motion direction changes.
As shown in fig. 5-6, the entire imitation of the left or right hand recognizes a change in direction of motion during the course of the action, when the front wearing hand is vertical relative to the ground, the y-axis is downward regardless of the left or right hand. When the user does not wear the device correctly according to the wearing prompt unit, the y axis is upward when the hand is vertical relative to the ground, so that the device can be judged to be worn reversely, the user can be prompted to wear the device correctly until the next step is executed when the device is worn correctly, the arm is parallel to the ground, the thumb of the hand is at the top, and the x axis is upward under the condition of the left hand. Whereas the negative x-axis is up if the right hand case.
In this embodiment, whether the wrist strap medical equipment is worn and whether correctly worn by the hand can be identified, and the left hand and the right hand can be automatically identified through hand action characteristics under the condition of correct wearing.
