Abstract

The invention provides an error touch prevention method based on a detection point density value. The method includes the steps that the detection point density value at a target position is obtained; whether touch is effective touch or not is judged; when it is judged that touch is effective touch, a touch screen generates a control command corresponding to the target position. The invention further provides an intelligent express delivery ark based on the method, and the intelligent express delivery ark comprises a touch recognition module, a main control module, a wireless module and an execution module. According to the intelligent express delivery ark based on the error touch prevention method, when the touch screen is touched, user touch and mosquito touch can be recognized and judged intelligently, accordingly operation selected by user touch is executed, and the problem of error touch, caused by mosquito attachment, on the touch screen of the intelligent express delivery ark is effectively solved. Express delivery senders and express delivery receivers can still send and take parcels normally in outdoor regions where many mosquitoes exist, and user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a false touch prevention method based on detection point density values ​​and an intelligent express cabinet. Background technique [0002] With the advancement of touch sensing technology, more and more smart express cabinets use touch screens as input tools. The capacitive touch screen is plated with long and narrow electrodes on the four sides of the touch screen, forming a low-voltage AC electric field in the conductor. When touching the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electrodes on the four sides will flow to the contacts, and the current strength is proportional to the distance from the finger to the electrode. The controller behind the touch screen is then It will calculate the proportion and strength of the current, and accurately calculate ...
