Anti-pet tread type alarm and method thereof for simultaneously measuring areas of a plurality of areas

Abstract

The invention relates to an anti-pet tread type alarm and a method thereof for simultaneously measuring areas of a plurality of areas. And the invention includes two parts: an anti-pet tread type alarm and a method thereof for simultaneously measuring areas of a plurality of areas. The method is embodied by a program of distinguishing a foot type by measuring areas of a plurality of areas. And the anti-pet tread type alarm is composed of a rectangle framework, a battery pack, an on-chip microcomputer system, a serial-in-parallel-out circuit, a parallel-in-serial-out circuit and a music circuit; an upper part and a bottom of the rectangle framework are respectively provided with a column electrode group and a row electrode group; and leads of the column electrode group are respectively connected to all parallel input terminals of the parallel-in-serial-out circuit in order as well as leads of the row electrode group are respectively connected to all parallel input terminals of the serial-in-parallel-out circuit in order. Moreover, a two dimensional coordinate system is established according to the leads of the column electrode group and the row electrode group; with utilization of the one-chip microcomputer, treaded areas are scanned and detected; contours of the treaded areas are tracked; areas in all contours are signed by ordinal numbers; calculation on areas by counting cells is carried out on areas in the contours; a foot type is determined; and it is decided whether an alarm sound is emitted or not. The method for measuring an area is completed and is suitable for one-chip microcomputers with all types.

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...

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"
