Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flow chart provided by the method for monitoring the number and intensity of hammering of the present invention. Referring to fig. 1, the method for monitoring the number and intensity of hammering in this embodiment may include the following steps:
s101, acquiring the acceleration of the hammer head of the health preserving hammer in the hammering direction through an accelerometer arranged on the health preserving hammer;
the accelerometer is also called an acceleration sensor, and is a sensor chip with three degrees of freedom directions. The accelerometer may be fixed to the curing hammer, and the present embodiment preferably fixes the accelerometer to the head of the curing hammer.
Fig. 2 is an accelerometer coordinate system provided by the method for monitoring the number and intensity of blows according to the present invention. Referring to FIG. 2, the X, Y and Z axes are the three degrees of freedom of the accelerometer. In the present embodiment, it is preferable that the direction of the Z axis is parallel to the hammer, that is, the hammering direction is parallel to the direction of the Z axis, and the acceleration in the hammering direction is the acceleration of the Z axis. When a user uses the health preserving hammer to beat muscles or acupuncture points, the contact point of the hammer head and the skin is vertical, so that the acceleration of the Z axis can be used as the judgment basis of the beating times and the beating strength.
During hammering, readings of the Z axis in the accelerometer can be read, and the ratio of the readings to the corresponding sensitivity of the accelerometer is calculated as the acceleration.
Specifically, in the present embodiment, the range of the accelerometer is preferably configured to be ± 16g, the sensitivity is 2048(LSB/g), and the output of the Z-axis is 2048(LSB) when horizontally placed as shown in fig. 1 under the influence of gravitational acceleration. Note that the unit of the index of the Z-axis output is not a unit of force, and unit conversion is required. For example, assuming that the reading accelerometer has a Z-Value as the index of the Z axis, the calculated acceleration a is: z _ value (LSB)/2048 (LSB/g). Wherein the gravity unit is 1 g-9.8 (m/s)2)。
The acceleration range can be configured into other ranges as required to meet the requirements of measuring the hammering times and strength, but the calculation method is the same as the above method, and the details are not repeated in this embodiment.

The preset single blow characteristic is then: firstly, the acceleration is negative; ② there is positive acceleration; and thirdly, when the motion characteristic meets the preset single-time beating characteristic, the negative acceleration is generated, and then the completion of one-time beating process can be determined.
S104, acquiring the maximum value of the acceleration in the hammering process;
when the health preserving hammer is used for beating the skin of a person, the acceleration of the Z axis reaches the maximum value, and the acceleration of the Z axis is the maximum value or the minimum value according to different settings in the positive direction. In the embodiment, the direction of the Z axis is taken as the positive direction, the A surface is taken as the working surface of the health preserving hammer, and when the health preserving hammer beats the skin of a person, the acceleration of the Z axis is a negative value and is the minimum value in the whole beating process.
And S105, calculating the hammering strength corresponding to the hammering process according to the maximum value.
After the maximum value of the acceleration is obtained, the beating force corresponding to the beating process can be calculated according to the maximum value. According to newton's second law, the blow force can be calculated according to the following steps:
a, obtaining the quality of the health preserving hammer;
and B, calculating the product of the mass and the maximum value, and taking the product as the hammering strength.
The monitoring method of the number of times of beating and dynamics of this embodiment installs the accelerometer on the health preserving hammer, and then can acquire the acceleration of hammer motion when beating, according to the situation of change at hammer motion in-process acceleration, then can confirm the motion characteristic of tup, when motion characteristic satisfies predetermined single and beats the characteristic, confirm for once to beat the process, and then can take notes the number of times of beating when the user beats at every turn, do not need the user oneself to count, the problem of the effect of beating can not appear counting error and influence. Can also acquire this maximum value of beating in-process acceleration, can calculate the dynamics of beating that this process of beating corresponds according to the maximum value of acceleration, the user can adjust the health hard through the dynamics of beating, selects reasonable dynamics to beat, makes health preserving hammer full play effect in the use, can effectively alleviate muscle discomfort, can not cause the muscle damage, has effectively improved the practicality of health preserving hammer.
Further, the method for monitoring the number and strength of hammering in the above embodiment may further include: and if the frequency of the hammering process reaches the preset hammering frequency, outputting the frequency upper limit for reminding.
Specifically, the user can set the preset hammering times according to the actual conditions of the user, and when the times of the hammering process of the user reach the preset hammering times, the upper limit reminding of the times can be output to inform the user that the hammering times are enough. For example, an audio alert is output to "beat enough, please rest".
Further, the method for monitoring the number and strength of hammering in the above embodiment may further include: and if the beating force is out of the preset beating force range, outputting a beating force overrun prompt.
Specifically, the user can set up according to the actual conditions of self and predetermine the dynamics of beating scope, and this embodiment can judge whether the dynamics of beating is greater than the maximum value of predetermineeing the dynamics of beating scope, if the dynamics of beating is greater than the maximum value of predetermineeing the dynamics of beating scope, and the too big warning of output dynamics, for example, "the dynamics of beating is big" is reminded to output pronunciation, if the dynamics of beating is less than the minimum of predetermineeing the dynamics of beating scope, and the undersize of output dynamics is reminded, for example, "the dynamics of beating is little" is reminded to output pronunciation.
