Problems solved by technology
[0003] Leading out the detection signal for opening the cover through the internal structure of the core will lead to complex structure of the core, cumbersome assembly, and increased volume of the core, resulting in high cost of the entire core, which ultimately increases the cost of the entire printing device
When using the movement with cover opening detection function, a larger space is required, and the internal structure of the printing device will be more complicated
The lead wire of the open cover signal is easily damaged during installation and cannot be repaired
[0004] A printing device without a cover opening detection function will feed the paper directly when it detects that the paper has been loaded but the cover is not closed, and the user needs to reprint and roll the paper, which is cumbersome and does not have a good user experience and use effect

Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0015] see Figure 1~3 , in an embodiment of the present invention, a method for intelligently detecting the opening of a printing device cover includes a magnet 3 and a Hall element U5, the magnet 3 is embedded on the right side of the paper compartment cover 1, and the Hall element U5 is placed directly below the magnet 3. The Hall element U5 is welded on the control board of the printing device 2. During the process of opening and closing the paper compartm...

The invention discloses a method for intelligently detecting the cover opening of printing equipment, and the printing equipment comprises a magnet and a Hall element U5. The magnet is inset at a right side of a paper cabin cover, and the Hall element U5 is placed exactly below the magnet. The Hall element U5 is welded on a control board of the printing equipment. A VCC power tube pin of the Hall element U5 is connected with a 3.3V power supply, a GND ground tube pin of the Hall element U5 is grounded, and an OUT tube pin of the Hall element U5 is connected with a universal IO port of a control main chip through a resistor R20. The control main chip discriminates whether the cover of the printing equipment is closed or not through the voltage of the universal IO port. The equipment is simple in structure, is convenient to assemble, is low in cost, is convenient to use, and is not liable to be damaged.
Description
technical field [0001] The invention relates to a detection method, in particular to an intelligent detection method for opening the cover of printing equipment. Background technique [0002] At present, the cover opening detection of many printing devices is realized through the internal structure of the core and circuit control, or there is no cover opening detection function. [0003] Leading out the cover opening detection signal through the internal structure of the core will lead to complex structure of the core, cumbersome assembly, increased volume of the core, high cost of the entire core, and ultimately increased cost of the entire printing device. When using a movement with a cover opening detection function, a larger space is required, and at the same time, the internal structure of the printing device will be more complicated. The lead wires of the cover open signal are easily damaged during installation and cannot be repaired. [0004] A printing device witho...
