Embodiment Construction

[0108] The invention comprises: a rectangular frame (1), a battery pack, a single-chip microcomputer system, a serial-in-parallel circuit, a parallel-in circuit, a music circuit and a contour method for measuring area to distinguish foot-type programs.

[0109] Rectangular frame (1) such as figure 1 As shown, there are a group of electrodes (14) and (13) on the top and bottom respectively, which are called column electrode group and row electrode group respectively. Each group of electrodes is composed of 72 exposed metal wires. These wires are independent of each other and the spacing Evenly, the directions of the wire arrangement of the two groups of electrodes (14) and (13) are perpendicular to each other (not strictly required), and are isolated and supported by the insulation on both sides (11) or (12) of the frame (1), and the whole rectangular frame Wrapped in insulating material, it looks like a footrest.

Abstract

The invention relates to an anti-pet tread type alarm and a method thereof for distinguishing a foot type by measuring an area with a contour method. And the invention includes two parts: an anti-pet tread type alarm and a method thereof for distinguishing a foot type by measuring an area with a contour method. The method is embodied by a program of distinguishing a foot type by measuring an areawith a contour method. 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 one by one; 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. According to the invention, the method for measuring an area is aimed at application to a treaded area that has been divided into blocks; and the method is also suitable for anti-theft and alarming 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 ​​several randomly distributed areas. Background technique [0002] In July 2010, the invention "anti-pet stampede alarm and its method of measuring area to distinguish foot shape" was submitted to the Patent Office of the State Intellectual Property Office for examination. With the help of single-chip microcomputer technology, the trampled area was detected with the "method of counting grid area" According to the size of the feet of people and small animals, the anti-pet stampede alarm is economical and practical. However, the "method of measuring the area by counting grids" does not take measures to distinguish the trampled area, so it cannot detect, identify and measure several trampled areas at the same time, and the result may be that the area of ​​some trampled areas Sum. Contents of th...
