Anti-pet trampling type alarm and method for distinguishing foot types through area measurement

Abstract

The invention comprises two parts. One is an anti-pet trampling type alarm and the other is a method for distinguishing foot types through area measurement. The method is embodied by a program of using the area measurement to distinguish the foot types. The alarm comprises: a rectangular frame, a battery pack, a single-chip microcomputer system, a serial-in parallel-out circuit, a parallel-in serial-in circuit and a music circuit. An upper part and a bottom of the rectangular frame are respectively provided with a column electrode group and a row electrode group. Leads are sequentially connected to each parallel input terminal of the parallel-in serial-in circuit and each parallel output terminal of the serial-in parallel-out circuit respectively. A two dimension coordinate system is established according to lead arrangement of the row electrode group and the column electrode group. The single-chip microcomputer is used to scan and detect the trampled area. The area is calculated through counting grids and the foot types are determined so as to decide whether an alarm is emitted. The alarm is suitable for antitheft alarm work.

Description

technical field [0001] The invention relates to the technical field of security electronics, in particular to an anti-pet stampede alarm device and a method for measuring the area of ​​an area to distinguish foot shapes. Background technique [0002] Stampede alarms involve distinguishing foot types to avoid alarms caused by pets stepping on them. Single-chip microcomputers can perform addition, subtraction, multiplication, division, and logic operations between bytes. Their arithmetic operations are weak, their expandable storage capacity is small, and their operation speed is low. Generally, they are not suitable for recognizing or matching graphics. However, the physical structure of a series of utility models such as the "stamped alarm" submitted to the Patent Office of the State Intellectual Property Office for review in mid-June 2010 is conducive to the application of single-chip technology to distinguish stampedes from humans and small animals. For example, the inven...
