Embodiment Construction

[0031] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0032] like figure 1 As shown, the flexible material-based pressure distribution measurement and analysis system involved in this embodiment includes:

[0033] The flexible pressure-sensitive sensing array 1 is composed of flexible pressure-sensitive sensing units in m rows and n columns. The arrangement of the array can be designed according to the measurement requirements. For example, when measuring the distribution of plantar pressure, the flexible pressure-sensitive sensing array 1 can be arranged as a shoe pad shape. For the specific structure of the flexible pressure-sensitive sensing array 1, please combine figure 2 and image 3 As shown, it includes a pressure sensitive unit 11 and an upper flexible circuit board 12 , a middle fixing layer 13 and a lower flexible circuit board 14 arranged in sequence. The pressure-sens...

Abstract

The invention discloses a pressure distribution measurement and analysis system based on a flexible material. The pressure distribution measurement and analysis system comprises a flexible pressure-sensitive sensing array, a row multiplexing circuit, a voltage mirror scanning circuit, a signal amplifying and conditioning circuit and a signal acquisition processing module, wherein the row multiplexing circuit is used for accessing a reference voltage to a driving end of each flexible pressure-sensitive sensing unit of a selected row; the voltage mirror scanning circuit is used for connecting the driving ends of the flexible pressure-sensitive sensing units of the selected row to high level, and connecting the rest rows to low level; the signal amplifying and conditioning circuit amplifies measured signals of the flexible pressure-sensitive sensing units of the selected row, and outputs the amplified signals to the signal acquisition processing module; and the signal acquisition processing module receives output signals of the signal amplifying and conditioning circuit, converts the signals into a pressure measurement result, and transmits the pressure measurement result to a displaymodule for displaying the pressure measurement result. The invention further discloses a pressure distribution measurement and analysis method based on the flexible material. The pressure distribution measurement and analysis system and the pressure distribution measurement and analysis method can be applied to a plurality of occasions where the pressure needs to be measured, effectively solve the coupling problem between the sensing units of the sensor, visually display the measured data, and facilitate control.

Description

technical field [0001] The invention relates to a pressure distribution measurement and analysis system and method, in particular to a pressure distribution measurement and analysis system and method based on flexible materials, belonging to the field of sensing technology. Background technique [0002] With the rise of artificial intelligence, the information interaction between robots and the outside world has increasingly become the research focus in the field of intelligent robot research. At present, the research on robot vision and hearing has achieved significant results and can be widely used in the technological society. However, due to the uncertainty and complexity of the tactile sense, people's research on the measurement of tactile information is only in the laboratory research stage. [0003] As an important branch of the robot's sense of touch, the pressure distribution of the robot foot can not only provide the feedback information of the external contact sur...
