Description
Technical field
The present invention relates to a kind of method of detection, specifically a kind of printing device is uncapped the method for Intelligent Measurement.
Background technology
At present, uncapping of a lot of printing device detects by movement inner structure and circuit control realization, or the function detected of not uncapping.
Drawing testing signal of uncapping by movement inner structure can cause cassette mechanism structure complicated, assembles loaded down with trivial details, increases movement volume, cause the cost of whole movement very high, finally improve the cost of whole printing device.Need larger space when using the movement with measuring ability of uncapping, the inner structure of printing device also can be more complicated simultaneously.The lead-in wire of signal of uncapping is easy to damage in installation process, and cannot keep in repair.
Do not uncap measuring ability printing device when detect fill paper but non-closing lid time just direct paper feed, user needs again to print and coil paper, more loaded down with trivial details, does not have good Consumer's Experience and result of use.
Summary of the invention
A kind of printing device is the object of the present invention is to provide to uncap the method for Intelligent Measurement, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of printing device is uncapped the method for Intelligent Measurement, comprise magnet and Hall element U5, magnet is embedded in the right side of paper Cang Gai, Hall element U5 is placed immediately below magnet, Hall element U5 is welded on the control panel of printing device, and the VCC power pin of Hall element U5 connects 3.3V power supply, GND ground pin ground connection, OUT pin, by the general I/O interface of resistance R20 connection control master chip, controls master chip and judges that printing device is closing lid or uncaps by the voltage difference of general I/O interface.
As the further scheme of the present invention: Hall element U5 is connected with resistance R20, resistance R20 with and general I/O interface between be connected, universal I/O port also connects stake resistance R22 and direct earth capacitance C17.
As the present invention's further scheme: after printing device powers on start, the main control chip of printing device can constantly read the universal I/O port magnitude of voltage be connected with the OUT pin of resistance R20, Hall element U5, then judge whether the difference of voltage and reference value is greater than the threshold voltage of setting, if the voltage difference detected is greater than the threshold values of setting, then judge that printing device is in closing lid state; If voltage difference is less than the threshold values of setting, then judge that printing device is in uncapped state.Universal I/O port is continuous cycle detection voltage after the power-up, real-time judge printing device uncapped state.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is simple, easy to assembly, with low cost, easy to use, not fragile.
Accompanying drawing explanation
Fig. 1 is surface structure schematic diagram of the present invention.
Fig. 2 is electrical block diagram of the present invention.
Fig. 3 is software flow pattern of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 3, in the embodiment of the present invention, printing device is uncapped the method for Intelligent Measurement, and comprise magnet 3 and Hall element U5, magnet 3 is embedded in the right side of paper storehouse lid 1, Hall element U5 is placed immediately below magnet 3, Hall element U5 is welded on the control panel of printing device 2, and in the process that paper storehouse lid 1 opens and closes, the relative distance of magnet and Hall element U5 changes, by the changes of magnetic field of Hall element U5 induced magnet 3, thus realize uncapping Intelligent Measurement.
The VCC power pin of Hall element U5 connects 3.3V power supply, GND ground pin ground connection, OUT pin is by the general I/O interface of resistance R20 connection control master chip, also connect stake resistance R22 and direct earth capacitance C17 between resistance R20 and general I/O interface, control master chip and judge that printing device is closing lid or uncaps by the voltage difference of universal I/O port.
After printing device 2 powers on start, the main control chip of printing device can constantly read the universal I/O port magnitude of voltage be connected with the OUT pin of resistance R20, Hall element U5, then judge whether the difference of voltage and reference value is greater than the threshold voltage of setting, if the voltage difference detected is greater than the threshold values of setting, then judge that printing device is in closing lid state; If voltage difference is less than the threshold values of setting, then judge that printing device is in uncapped state, universal I/O port is continuous cycle detection voltage after the power-up, real-time judge printing device uncapped state, ensures that printing device is working properly.
When closing lid, Hall element senses magnetic field, and the magnitude of voltage of output and the difference of reference value are comparatively large, send closing lid signal; When uncapping, Hall element can't detect the magnetic field of some strength, the magnitude of voltage of output and the difference of reference value less, then printing device is judged as uncapping.
Cassette mechanism structure of the present invention is simple: the uncap printer core structure of closing lid measuring ability of this intelligence is relatively simple, convenient for production.The uncap printer core of closing lid measuring ability of tradition structurally needs to increase button, and will to be uncapped the extraction of closing lid signal by wire, printing device judges the closing lid of uncapping of printing device by detection signal.
Printing device inner space is little: this intelligence uncap detection method need printing device inner space less, only need staying a roundlet slot at the edge of the paper Cang Gai of printing device, in printing device fuselage cover thereunder, staying the roundlet position of a similar size for placing Hall element.
The present invention is not fragile: this intelligent detecting method is by the mode of wireless induction magnetic field intensity, and intelligence carries out closing lid detection of uncapping.The detection signal lead-in wire be embedded in cassette mechanism structure is easy to damage when assembling, and causes using, even can not repair.
The present invention assembles simply: detecting sensor is welded on printing device and controls on mainboard, magnet is embedded in the circular groove position of printing device paper Cang Gai, because the detection in printer core is realized by mechanical means, and the element of the inside is very little, so the assembling more complicated of pick-up unit in printhead.
The present invention is easy to use: the printing device detected with closing lid of uncapping is very simple in use, if user opens paper Cang Gai, can automatically stop printing and revolution, thus protection printer, have prompting simultaneously.
The present invention is cost-saving: utilize the method for Hall element and magnet simple due to structure, reduce the volume of printing device, reduce production cost
