Telescopic type infant health scale

Abstract

The invention relates to a telescopic type infant health scale. According to the telescopic type infant health scale, a sliding plate capable of stretching and retracting according to the height of a baby is arranged on an upper cover in an erected mode, and four sets of weighing sensors and two sets of displacement sensors are arranged below the upper cover; on one hand, the four sets of weighing sensors form a bridge type circuit, an elastic body is stressed to be changed in shape and transfers the shape changing to a strain gauge, and the sensors convert a pressure signal into a current analog signal; on the other hand, the resistance values of the two sets of the displacement sensors are changed through sliding of the sliding plate. The two sets of signals are input into an MCU controlling unit and are mixed with the analog signals in the controlling unit and are amplified in a low-noise mode, then A / D conversion is conducted on the signals, the analog signals are converted into digital signals, the digital signals are input into a CPU, analyzing and processing of the signals are accomplished, and the signals are displayed through a liquid crystal display. According to the telescopic type infant health scale, the sensor technology is adopted, and measuring of body weight and body height is achieved through the pressure sensors and the displacement sensors.

Description

1. Technical field [0001] The invention relates to a telescopic baby health scale, which belongs to an electronic product for weighing a baby, in particular to a baby health scale capable of measuring the height of a baby through a displacement sensor. 2. Background technology [0002] At present, the known baby health scales simply measure the baby's weight, but the simple weight change cannot comprehensively analyze the baby's growth status, and the comprehensive analysis of weight and height can understand the baby's growth and health status more accurately and in time . 3. Contents of the invention [0003] The object of the present invention is to provide a telescopic baby health scale, which is a baby health scale capable of measuring the height of a baby through a displacement sensor. [0004] The technical solution adopted to realize the object of the present invention is: a telescopic baby health scale, comprising: a load cell, a displacement sensor, a liquid cry...

AI Technical Summary

Problems solved by technology

[0005] The telescopic baby health scale provided by the present invention not only solves the problem of weighing the baby's weight, but also can comprehensively analyze the baby's growth status according to the change of the baby's weight. Through the comprehensive analysis of the baby's weight and height change, it can be more accurate , keep abreast of the baby's growth and health status
