Anti-pet stampede alarm and its method for measuring the area of ​​several areas at the same time

Abstract

The anti-pet stampede alarm and the method for simultaneously measuring the area of ​​several areas include two parts: the anti-pet stampede alarm and the method for simultaneously measuring the area of ​​several areas; A rectangular frame, a battery pack, a single-chip microcomputer system, a series-in parallel-out circuit, a parallel-in series circuit and a music circuit are composed, wherein, the upper part and the bottom part of the rectangular frame are respectively provided with column and row electrode groups, and the wires are respectively connected to Parallel input terminals of the serial-in circuit and parallel output terminals of the serial-in-parallel-out circuit are incorporated. Establish a two-dimensional coordinate system according to the arrangement of the wires of the two electrode groups in the row and column, scan and detect the trampled areas with the help of a single-chip computer, track their outlines, use ordinal numbers to mark the areas within each outline, count the grids for each area to calculate the area, and judge the feet type and decide whether to sound the alarm. The method for measuring the area is complete and applicable to various types of single-chip microcomputers.

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 ​​several randomly distributed areas. Background technique [0002] In July 2010, the invention "Anti-Pet Stampede Alarm and Its Method of Measuring Area and Distinguishing Foot Shape by Contour Method" submitted to the Patent Office of the State Intellectual Property Office for review uses single-chip microcomputer technology to track the contour of the trampled area first, and then uses "digital The method of measuring the area of ​​the grid "detects the area of ​​the area within the outline, and distinguishes the foot shape of people and small animals based on this. Its anti-pet stampede alarm only alarms people's stampede, avoiding false alarms caused by stampede of small animals. However, in theory, if multiple trampled areas appear at the same time, although the result of measuring the are...

AI Technical Summary

Problems solved by technology

However, in theory, if multiple trampled areas appear at the same time, although the result of measuring the area by the contour method is effective for distinguishing the foot shapes of humans and small animals, the one-to-one correspondence between them and each trampled area is not clear. Moreover, as the number of times the outline of the tracking area increases, it will shrink "circle by circle"
