Anti-pet stampede alarm and its method of measuring area length and distinguishing foot type

Abstract

The anti-pet stampede alarm and the method of distinguishing the foot shape by measuring the length of the area include two parts: the anti-pet stampede alarm and the method of distinguishing the foot shape by the length of the measuring area; Composed of a rectangular frame, a battery pack, a single-chip microcomputer system, a serial input parallel output circuit, a parallel serial input circuit and a music circuit. Among them, the upper part and the bottom of the rectangular frame are respectively provided with column and row electrode groups, and the wires are respectively connected to the parallel circuit. Each parallel input end of the serial input circuit and each parallel output end of the serial input parallel output circuit. The program establishes a two-dimensional coordinate system according to the arrangement of the wires of the two electrode groups, scans and detects the trampled area with the help of a single-chip microcomputer, tracks the outline of the area, calculates the distance between the outline points and saves the larger one as the length of the area, and judges Foot type and determine whether to send out the alarm sound, suitable for anti-theft alarm 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.
