Pet trample-preventing alarming device and method for classifying foot shapes by measuring length of area

Abstract

The invention relates to a pet trample-preventing alarming device and a method for classifying foot shapes by measuring a length of an area, which comprises the pet trample-preventing alarming device part and the method part for classifying the foot shapes by measuring the length of the area. The method is reflected on a program for classifying the foot shapes by measuring the length of the area. The alarming device consists of a rectangular framework, a battery pack, a single chip system, a serial-in parallel-out circuit, a parallel-in serial-in circuit and a music circuit, wherein the upper part and the bottom part of the rectangular framework are respectively provided with rows of electrode groups, and conducting wires of the electrode groups are sequentially connected to each parallel input end of the parallel-in serial-in circuit and each parallel output end of the serial-in parallel-out circuit. The program establishes a two-dimensional coordinate system according to array of the conducting wires of the two electrode groups, an area which is pedaled is scanned and detected by a single chip, an outline of the area is traced, a distance between every two outline points is calculated, the maximal distance between two outline points is stored and is adopted as the length of the area, the foot shape is judged, and the alarm is judged whether to issue. The pet trample-preventing alarming device is suitable for the antitheft alarming work.

Description

technical field [0001] The invention relates to the technical field of security electronics, in particular to an anti-pet trampling alarm device and a method for measuring the length of a trampled area. Background technique [0002] In mid-June 2010, a series of utility models such as the "stamped alarm", "anti-touch stamped alarm" and "anti-touch vibration stamped alarm" submitted to the Patent Office of the State Intellectual Property Office for review will emit light when stepped on. The sound or light alarm signal is simple in structure, economical and practical, but these alarm devices cannot distinguish whether they are trampled by people or trampled by small animals such as cats, dogs, mice or chickens. When trampled by these pets, unnecessary alarm. Considering that the width of the human foot is significantly larger than that of the above-mentioned pets, the invention patent "Anti-pet stampede alarm and its method for distinguishing trampled by humans and small ani...

[0002] In mid-June 2010, a series of utility models such as the "stamped alarm", "anti-touch stamped alarm" and "anti-touch vibration stamped alarm" submitted to the Patent Office of the State Intellectual Property Office for review will emit light when stepped on. The sound or light alarm signal is simple in structure, economical and practical, but these alarm devices cannot distinguish whether they are trampled by people or trampled by small animals such as cats, dogs, mice or chickens. When trampled by these pets, unnecessary the alarm

Considering that the width of the human foot is significantly larger than that of the above-mentioned pets, the invention patent "Anti-pet stampede alarm and its method for distinguishing trampled by humans and small animals" submitted for examination at the same time, with the help of single-chip microcomputer technology, proposed A method of measuring the width of the trampled area to distinguish trampled people from small animals, and based on this, a series of utility models for anti-pet stampede alarms are designed. They only warn trampled people and ignore trampled pets.
