Dot-matrix sole pressure measuring device and detection method thereof

Abstract

The invention relates to a dot-matrix sole pressure measuring device and a detection method thereof. The structure of the device comprises pressure measuring devices and an electric control system. The pressure measuring devices are electrically connected with the electric control system and arranged on a panel in an array. The pressure measuring devices are rod-shaped. Sole supporting surfaces are formed by the top ends of the pressure measuring devices and separated from each other. The sole supporting surfaces perform up-down motion with changes of supporting weight. The dot-matrix sole pressure measuring device comprises the multiple pressure measuring devices in shapes of rods. The pressure measuring devices are distributed in a dot-matrix form. The heights of the top ends of the pressure measuring devices can change according to different support weight. Therefore, pressure of all positions of the sole can be precisely measured. Furthermore, no matter what the shape and the size of the sole are, the sole can be within the measurement range. In addition, absolute value of sole pressure distribution is calculated according to an internal software algorithm of a master control unit and a sole three-dimensional shape can be scanned.

Description

technical field [0001] The invention relates to a plantar pressure measuring device, in particular to a dot-matrix plantar pressure measuring device and a detection method thereof. Background technique [0002] Chinese Patent Document No. CN103462619A disclosed a plantar pressure measuring device on December 25, 2013, which includes a left foot insole and a right foot insole, a signal conditioning circuit, a data acquisition circuit and a computer; the left foot insole and the right foot The insoles are all equipped with 4 pressure sensors, and the 4 pressure sensors of the left insole and the 4 pressure sensors of the right insole are arranged symmetrically; the installation positions of the 4 pressure sensors are: one is installed at the heel of the insole, Install two on the palm and one on the toe of the insole; the signal output of each pressure sensor is connected to the input of the signal conditioning circuit, the output of the signal conditioning circuit is connecte...

AI Technical Summary

Problems solved by technology

The pressure sensor of this structure is set on an integral insole, which cannot accurately measure the pressure generated by each position of the sole of the foot. In addition, the pressure sensor is a diaphragm pressure sensor, and the measured pressure value is not an absolute pressure. Data deviation is large

[0003] In addition, the supporting surface of the plantar pressure measuring device is fixed, but the shape of the sole of the foot is not flat, so when standing on the plantar pressure measuring device, many parts of the sole of the foot cannot be aligned with the corresponding supporting surface. Contact, so that the pressure value of more places on the sole of the foot cannot be accurately measured
