In embodiments of the present invention, the pressure rating that detection unit 02 detects pressure can be the dynamics etc. of detection pressure Grade, detection method include:
Determine the size of the pressure value of pressure；The size of pressure value is compared from preset different pressing dynamics range Compared with, when the size of the pressure value of pressure belongs to any one of pressing dynamics range, by pressure be determined as belonging to should be by Pressing dynamics grade corresponding to surging range.
In embodiments of the present invention, for the size of clear pressure applied, we in advance define different pressure values For different dynamics grades, such as dynamics grade 1, dynamics grade 2, the rest may be inferred for dynamics grade 3 ....It is right in specific each grade The size for the pressure value answered is how much different definition can be carried out according to different users, e.g., for young man, strength It is larger, it can be set to correspond to biggish pressure value in each grade in the setting of dynamics grade, e.g., 50g-60g belongs to power Degree grade 1,60g-70g belongs to dynamics grade 2,70g-80g belongs to dynamics grade 3 (it should be noted that due to acceleration of gravity It is constant, the size of pressure is indicated with weight here, is described below similarly.)；For the elderly and children, strength is smaller, It can be set to correspond to lesser pressure value in each grade in the setting of dynamics grade, e.g., 20g-35g belongs to dynamics grade 1,35g-50g belongs to dynamics grade 2,50g-65g belongs to dynamics grade 3.Above content is only a specific implementation of the invention Example, in other embodiments, we can also be corresponding to dynamics grade and each dynamics grade according to different application scenarios The size of pressure value does corresponding adjustment.
In the above content, how we predefines the dynamics grade of pressure if describing in detail.Below by Specific embodiment is discussed in detail how the dynamics for applying pressure at the terminal is determined by scheduled pressure dynamics rate range Grade.Here it is illustrated for continuing the dynamics rate range of the young man defined in above-described embodiment, in above-mentioned reality It applies in example, we mention, and for young man, strength is larger, can be set in each grade in the setting of dynamics grade For the biggish pressure value of correspondence, e.g., 50g-60g belongs to dynamics grade 1,60g-70g belongs to dynamics grade 2,70g-80g belongs to power Degree grade 3 (it should be noted that since acceleration of gravity is constant, is indicated the size of pressure here with weight, is described below same Reason.)；Still by taking this range as an example, if outer bound pair terminal is applied with a pressure, detect that the pressure size of the pressure is 75g, At this moment the power of this 75g is compared with above-mentioned pressure limit 50g-60g, 60g-70g, 70g-80g respectively, comparison result It is found that the power of this 75g belongs within the scope of the dynamics of 70g-80g, and the dynamics range of the 70g-80g correspond to it is pre-set Dynamics grade 3, therefore the power for this 75g that outer bound pair terminal applies is determined as dynamics grade 3.
