Description
Technical field
The invention belongs to stylus printer fields, and in particular to a kind of photoelectric sensor threshold values suitable for stylus printer
The method of adjust automatically.
Background technique
Stylus printer detects paper usually using photoelectric sensor, due to vulnerable to ambient and falling grey paper scrap naturally
It influences, the threshold values of sensor setting is frequently necessary to manually adjust, and has not only influenced user's use, but also the Maintenance Resource that waste is valuable.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of photoelectric sensor threshold values suitable for stylus printer
The method of adjust automatically, it is contemplated that sensor is influenced to be a progressive process by dust paper scrap, if can timing automatically into
Row adjustment allows threshold values is synchronous with the degree of sensor dust stratification to rise, can achieve the purpose that non-maintaining.
The technical scheme is that：A kind of photoelectric sensor threshold voltage adjust automatically suitable for stylus printer
Method, specific step is as follows：Every time booting after, printer moves back paper automatically first, moved back after or continuously move back paper act N seconds after,
Automatic setting threshold voltage；
The setting method of the threshold voltage is as follows：Pass through AD (Analog-Digital Conversion analog-to-digital conversion)
Mouth measures sensor sensing voltage value A, and the relationship for calculating threshold voltage B, A and B is as follows：Work as A<When=2.6V, B=A+0.6；When
A>When 2.6V, B=3.2V；
Printer advance and retreat paper all determines whether paper by the threshold values being arranged automatically later.
Further, the printer moves back paper automatically first, after having moved back or continuously moves back automatic setting after paper acts N second
Threshold voltage, it is specific as follows：When moving back paper automatically, sensor judges whether no paper in preset threshold value voltage；If it is determined that without paper, into
The automatic setting threshold voltage of row operates；This is generally to move back the successful process of paper.If it is determined that having paper, and in the defined N seconds time
Paper is not exited, is judged as that preset threshold value voltage is no longer valid or paper feed channel has paper jam, warning note user clears up, while still
Automatic setting threshold voltage is so carried out to operate；This is the process flow generally moved back in the case of paper is unsuccessful or dust stratification.
Further, if it is determined that there is paper, and paper is not exited in the defined N seconds time, is judged as preset threshold value voltage
No longer valid or paper feed channel has paper jam, and warning note user cleaning after user's cleaning, if switching on and shutting down are primary again again, senses
Device threshold voltage can automatically restore near factory-said value or factory-said value.Even if i.e. this method has the setting of cause specific threshold values wrong
Accidentally, switching on and shutting down can restore automatically normal again.
Further, the N is 2-4.
Beneficial effect：The present invention provides a kind of side of photoelectric sensor threshold values adjust automatically suitable for stylus printer
Method, it is contemplated that sensor is influenced to be a progressive process by dust paper scrap, if can timing be adjusted automatically, allow threshold values
It is synchronous with the degree of sensor dust stratification to rise, it can achieve the purpose that non-maintaining.Using the adjustment week of photoelectric sensor of the present invention
Phase is primary by original cleanings in 2 months, manually adjusts, and is reduced to every 6 months and cleans primary, adjust automatically.Both having improved user makes
With comfort level, and save valuable Maintenance Resource.
Specific embodiment
The present embodiment is directed to the stylus printer of public security, and the bill used is no more than A4 length, moves back paper machine in printer
Structure moves back paper in 2 seconds under normal circumstances enough.A kind of photoelectric sensor threshold voltage adjust automatically suitable for stylus printer
Method, specific step is as follows：Every time booting after, printer moves back paper automatically first, moved back after or continuously move back paper act 2 seconds after,
Automatic setting threshold voltage；The setting method of the threshold voltage is as follows：Pass through AD (Analog-Digital Conversion
Analog-to-digital conversion) mouth measures sensor sensing voltage value A, and the relationship for calculating threshold voltage B, A and B is as follows：Work as A<When=2.6V, B
=A+0.6；Work as A>When 2.6V, B=3.2V；Printer advance and retreat paper all determines whether paper by the threshold values being arranged automatically later.
Wherein, printer moves back paper automatically first, has moved back after moving back paper movement afterwards or continuously 2 seconds, threshold voltage is arranged automatically,
It is specific as follows：When moving back paper automatically, sensor judges whether no paper in preset threshold value voltage；If it is determined that being set automatically without paper
Set threshold voltage operation；This is generally to move back the successful process of paper.If it is determined that there is paper, and do not exited in the defined N seconds time
Paper is judged as that preset threshold value voltage is no longer valid or paper feed channel has paper jam, warning note user cleaning, while still carrying out certainly
Dynamic setting threshold voltage operates；This is the process flow generally moved back in the case of paper is unsuccessful or dust stratification.After user's cleaning, if again
Switching on and shutting down are primary again, and sensor valve threshold voltage can automatically restore near factory-said value or factory-said value.Even if i.e. this method has spy
Mistake is arranged in different reason threshold values, and switching on and shutting down can restore automatically normal again.
The present invention is influenced to be a progressive process by dust paper scrap in view of sensor, if can periodically carry out automatically
Adjustment allows threshold values is synchronous with the degree of sensor dust stratification to rise, can achieve the purpose that non-maintaining.Using photoelectric sensing of the present invention
The adjustment period of device is primary by original cleanings in 2 months, manually adjusts, and is reduced to every 6 months and cleans primary, adjust automatically.Both
User's usage comfort is improved, and saves valuable Maintenance Resource.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
