Array type scanning intelligent identification weighing scale and automatic identification method thereof

Abstract

The invention discloses an intelligent identity recognition weighing scale adopting array type scanning and an automatic identity recognition method thereof. The intelligent identity recognition weighing scale comprises a weighing scale body, wherein the weighing scale body comprises a bearing base plate, a weight measuring pressure sensor and a substrate which are overlapped sequentially from top to bottom; the weighing scale is characterized in that a top panel is arranged on the bearing base plate; a switch circuit board is arranged between the top panel and the bearing base plate; reset type key switches are arranged on the switch circuit board; one end, far away from the switch circuit board, of each reset type key switch, passes through the top panel and extends to the upper part of the top panel; the reset type key switches are arranged on the top panel in N rows and M lines of arrays; all the reset type key switches form a switch pressure sensor matrix, wherein N and M are both larger than or equal to 40, the measurement is rapid, the identity of a user can be immediately determined according to the size of the foot surface without enabling the user to take off shoes or socks, and meanwhile, the identity of the user can be recognized more accurately.

Description

technical field [0001] The invention relates to an intelligent weight scale, in particular to an array scanning intelligent identity recognition weight scale and an automatic identity identification method thereof. Background technique [0002] Scales are commonly used measuring tools at home. Common scales are only used to measure the weight of individuals. Patent No. 201320509748 has disclosed a scale that can identify individuals. The structure of this scale includes a panel and a panel. There is a weight display, and a pressure sensor is installed on the lower part of the panel. The scale also includes a foot length sensor. The foot length sensor adopts a plurality of temperature sensors arranged side by side for sensing the temperature of the feet. When the user places the feet on these After the temperature sensor is installed, the temperature sensor can sense the distance between the two temperature sensors on the outermost edge, and finally confirm the user's foot le...

[0002] Scales are commonly used measuring tools at home. Common scales are only used to measure the weight of individuals. Patent No. 201320509748 has disclosed a scale that can identify individuals. The structure of this scale includes a panel and a panel. There is a weight display, and a pressure sensor is installed on the lower part of the panel. The scale also includes a foot length sensor. The foot length sensor adopts a plurality of temperature sensors arranged side by side for sensing the temperature of the feet. When the user places the feet on these After the temperature sensor is installed, the temperature sensor can sense the distance between the two temperature sensors on the outermost edge, and finally confirm the user's foot length, and use the foot length to confirm the user's identity. This identifiable identity scale can only be measured in one dimension Obtain simple and rough paw length information, and because the temperature sensor with slow response speed is used as the acquisition method, its acquisition and processing require a long waiting time, and the temperature transition effect of the edge part will lead to inaccurate measurement; due to temperature measurement It is a temperature measurement line, so the user must adjust the longest part of the foot to coincide with the temperature measurement line every time. Since the length of the feet of people with similar heights is relatively close, there is no more accurate identification of the user's identity, such as height Similar father and son, the length of the feet of the two people is very close, but the size of the feet of the two people is quite different. Using the above-mentioned measuring device, it is impossible to accurately determine the identity of the user, otherwise the results of each measurement will be very different; due to the temperature sensor, so must be measured barefoot, difficult to use in colder weather
