Fig. 2 is refer to, the embodiments of the invention provide a kind of triggering method of testing of the product containing capacitance sensor, below
Referred to as triggering method of testing, comprises the following steps：
Step S100, obtain by the first capacitance formed after die pressing product 6, press the sense of the product 6 containing capacitance sensor
Region is answered, a capacitance can be formed.
Step S200, the second capacitance formed after release product 6, i.e., when no longer pressing die pressing product 6, the sense of product 6 are obtained
Region is answered to form another capacitance.
Step S300, the electric capacity calibration value of product 6 is worth to according to the first capacitance and the second electric capacity, electric capacity calibration value is
For the difference between the first capacitance and the second capacitance.
Step S400, capacitance deviation value is obtained according to the electric capacity threshold values of electric capacity calibration value and product 6.Electric capacity threshold values is product
Successful capacitance is triggered, is an average reference value being worth to according to the demarcation of multiple electric capacity of bulk article；Each product 6
Electric capacity calibration value it is different, therefore, deviation be present between the electric capacity calibration value and electric capacity threshold values of each product 6, this deviation is just
It is capacitance deviation value.
Step S500, write using capacitance deviation value as capacitance compensation value in the triggering algorithm of product 6, be compensated triggering
Algorithm.
Triggering algorithm is a set of identical algorithm that each product 6 follows when carrying out trigger action, and the triggering of product 6 is grasped
Make to judge whether to trigger successfully according to triggering algorithm.But for individual product 6, in correct trigger action, touched according to same
Hair algorithm can not trigger success.Or individual product 6 is excessively sensitive and accurate, by external environmental interference, also according to same
Triggering algorithm causes false triggering success, and these are all because product 6 has capacitance deviation value.
Therefore the triggering method of testing of the present invention is to each product 6 by demarcating, and according to the result of demarcation with batch
The electric capacity threshold values that volume production product 6 share compares, and is compensated both differences as offset into triggering algorithm, obtains new benefit
Triggering algorithm is repaid, when carrying out trigger action again so as to the product, new triggering can be carried out according to compensation triggering algorithm and judged,

In the present embodiment, step S300 is optimized, in step S300 according to the first capacitance and the second electric capacity
The electric capacity calibration value of product 6 is worth to, is specially：Second capacitance subtracts the first capacitance, obtains electric capacity calibration value.Generally
Ground, the first capacitance formed by die pressing product 6 are less than the second capacitance that release product 6 is formed, then the electric capacity calibration value obtained
For on the occasion of.It is of course also possible to which the first capacitance is subtracted into the second capacitance, then the electric capacity calibration value obtained is negative value, is taken definitely
Follow-up judgement is can be equally used for after value.
In the present embodiment, step S400 is optimized, in step S400 according to electric capacity calibration value and the electricity of product 6
Hold threshold values and obtain capacitance deviation value, be specially：Electric capacity threshold values subtracts electric capacity calibration value, obtains capacitance deviation value.When electric capacity is demarcated
When value is less than electric capacity threshold values, it is meant that correct trigger action can not reach triggering and successfully require that then electric capacity calibration value is less than normal,
Obtained capacitance deviation value is negative value.When electric capacity calibration value is more than electric capacity threshold values and exceedes certain limit, it is meant that product 6

Existing product 6 can not be triggered correctly, and capacitance threshold value is relatively low.For product 6 in higher sensitivity, easily by external environmental interference,
Cause false triggering, capacitance threshold value is higher.
Certainly, algorithm is triggered in addition to using above-mentioned algorithm, and the present embodiment additionally provides another triggering algorithm, specifically
For：
Pressing capacitance by being formed after die pressing product 6 subtracts the release capacitance formed after release product 6, obtains electric capacity threshold
Value, takes absolute value to capacitance threshold value, obtains absolute capacitance threshold value, wherein, capacitance threshold value is a difference, and is negative value, then absolutely
To capacitance threshold value be on the occasion of；
Compare absolute capacitance threshold value and the size of electric capacity threshold values, if absolute capacitance threshold value is more than or equal to electric capacity threshold values,
Then product triggers successfully, if absolute capacitance threshold value is less than electric capacity threshold values, product triggering is unsuccessful.
For the first above-mentioned triggering algorithm, writing capacitance deviation value as capacitance compensation value in step S500 is triggered
In algorithm, obtained compensation triggering algorithm is specially：
The release capacitance formed after release product 6 is subtracted by the pressing capacitance formed after die pressing product 6, obtains electric capacity threshold
Value.
Capacitance compensation value and capacitance threshold value are subjected to addition or subtraction process, obtain correcting capacitance threshold value；Specifically, electricity is worked as
Hold offset (i.e. capacitance deviation value) by electric capacity threshold values subtract electric capacity demarcation be worth to when, then amendment capacitance threshold value by capacitance threshold value
It is worth to plus capacitance compensation；When capacitance compensation value (i.e. capacitance deviation value) subtracts electric capacity threshold values by electric capacity calibration value to be obtained,
Then amendment capacitance threshold value subtracts capacitance compensation by capacitance threshold value and is worth to.
Compare amendment capacitance threshold value and the size of electric capacity threshold values, if amendment capacitance threshold value is more than or equal to electric capacity threshold values,
Then product triggers successfully, if amendment capacitance threshold value is less than electric capacity threshold values, product triggering is unsuccessful.
It can be seen that by being compensated to original triggering algorithm, new amendment capacitance threshold value is obtained, by electric capacity threshold less than normal
Value adds capacitance compensation value, so that correctly trigger action meets to trigger successful condition；Electric capacity threshold values bigger than normal is subtracted
Capacitance compensation value, so that false triggering operation can not meet to trigger successful condition, avoid false triggering success.New triggering is calculated
Method improves the accuracy of product identification trigger action.
For above-mentioned second triggering algorithm, writing capacitance deviation value as capacitance compensation value in step S500 is triggered
In algorithm, second of compensation triggering algorithm is obtained, is specially：
Pressing capacitance by being formed after die pressing product 6 subtracts the release capacitance formed after release product 6, obtains electric capacity threshold
Value, takes absolute value to capacitance threshold value, obtains absolute capacitance threshold value.
Capacitance compensation value and absolute capacitance threshold value are subjected to addition or subtraction process, obtain correcting capacitance threshold value；Specifically,
When capacitance compensation value (i.e. capacitance deviation value) subtracts electric capacity demarcation by electric capacity threshold values to be worth to, then capacitance threshold value is corrected by absolute
Capacitance threshold value is worth to plus capacitance compensation；When capacitance compensation value (i.e. capacitance deviation value) subtracts electric capacity threshold values by electric capacity calibration value
When obtaining, then amendment capacitance threshold value subtracts capacitance compensation by absolute capacitance threshold value and is worth to.
Compare amendment capacitance threshold value and the size of electric capacity threshold values, if amendment capacitance threshold value is more than or equal to electric capacity threshold values,
Then product triggers successfully, if amendment capacitance threshold value is less than electric capacity threshold values, product triggering is unsuccessful.
