In detecting second pressure that above-mentioned regional area is subject to and export corresponding electric signal.Wherein, second pressure i.e. the second sensing zone
The pressure suffered by local surfaces contacted with second pressure sensor 144.In specific implementation, second pressure sensor 144
The middle position of the second side surface of pressing plate can be arranged on.
Wherein, when the human body weight and human body respiration by imitating true man test sensing zone, detailed process
Can be：The work that driver 131 applies the sensing zone based on friction generator according to pre-set programs change Anchor plate kit 140
Firmly, the different human body weights of sensing zone are acted on to complete the test to sensing zone so as to imitate；Driver 131 is according to pre-
If program makes Anchor plate kit 140 carry out pumping by a small margin in predeterminated position, to change Anchor plate kit to being based on rubbing
The pressure of the sensing zone of generator is wiped, so as to imitate the different respiratory intensities for acting on sensing zone, beat intensity and other bodies

Plate will not be damaged because of stress value mutation with the internal element for protecting sensing zone, be ensured to the mechanism of sensing zone
Sense the accuracy of tape test.Simultaneously as buffer body has the flexible characteristic similar to human body, therefore by setting buffer body
Also the process that human body applies sensing zone active force can be more accurately imitated, so as to improve the accuracy of test result.Specifically
In implementation, the material of buffer body 145 can be the larger material of the elasticity such as silica gel or air bag.Also, may be used also inside supporting box
To be further provided with mattress of the surface as flexible surface.Mattress is arranged on the underface of Anchor plate kit, for being surveyed in sensing zone
Tested sensing zone is carried during examination.Wherein, since mattress surface is flexible surface, by setting mattress also can be right

144 determine the pressure suffered by sensing zone jointly.Specifically, when imitating human body weight to sensing zone application pressure, mould is set
Imitative human body weight to sensing zone pressure applied value be basic pressure value.In specific implementation, due to different basic pressures
Being worth influences significantly, therefore sensing zone is needed first during the test through second pressure sensor the output signal of sensing zone
144 demarcate corresponding basic pressure value.Since the surface of mattress and sensing zone is all flexible body surface, surface is in stress
Deform in the process it is larger, simultaneously as second pressure sensor 144 is pliable pressure sensor (for example, can be in specific implementation
For resistance-type diaphragm pressure sensor etc.), it is easily deformed upon by during active force during the test, so as to cause it
Accuracy of detection can be relatively low due to above-mentioned deformation, thus second pressure sensor 144 every time measure can because the plastic deformation of itself with
And the deformation on above-mentioned flexible body surface causes very big error to test result, so needing by repeatedly measuring and strictly determining
The flatness of plane that sensing zone and second pressure sensor 144 contact could correctly demarcate basic pressure value.Wherein,
In the case where sensing zone placement location and scale error be little and the factors such as mattress are constant, first pressure sensor 143
The variation of stress value is smaller, therefore after second pressure sensor 144 demarcates basic pressure value, can specifically pass through first pressure
Sensor 143 is monitored the stress of the sensing zone in test process, and detailed process is as follows：It is examined by output peripheral equipment
The electric signal that first pressure sensor 143 exports is surveyed, when larger fluctuation occurs in the electric signal that first pressure sensor 143 exports
When, basic pressure value is re-scaled by second pressure sensor 144, accurately to be tested sensing zone.The above process
Second pressure sensor 144 can not only be monitored in real time, found in time and prevent second pressure sensor 144 from testing
Occur large error in the process and happen accuracy to ensure sensing zone test process, additionally it is possible to simplify testing process, from
And effectively promote detection efficiency.
In specific implementation, first pressure sensor 143 may be used as S type pull pressure sensor, precision 0.2%；
Second pressure sensor 144 may be used as resistance-type diaphragm pressure sensor, precision 3%.Wherein, due to second pressure
Sensor is 144 pliable pressure sensors, and corresponding deformation, therefore and first pressure sensor can occur when by active force
143 in contrast, and the accuracy of detection of second pressure sensor 144 is less than the accuracy of detection of first pressure sensor 143, therefore
In specific implementation, the stress of second pressure sensor 144 is detected using first pressure sensor 143.
Wherein, when the output signal to sensing zone is detected, the reason of causing sensing zone output signal abnormal, is main
Including：First, buffer body variation --- the gas flow mainly in gasbag-type buffer body changes or loosens, and output is caused to be believed
Number exception；Second, the debugging deviation of transmission mechanism --- predominantly initial point change in location causes output signal abnormal；Third,
Sensing zone self reason --- mainly thickness mutation, caused output signal are abnormal.Therefore work as first pressure sensor
When 143 pressure value is mutated, above-mentioned factor can be excluded successively, it is timely so as to be carried out to the abnormal cause of test equipment
It is effective to judge, to promote the accuracy of sensing zone detection process.
Optionally, acceptable further setting signal processor in the utility model, wherein, signal processor and the first pressure
