Abstract
The present disclosure relates to a sensing device and a method for processing sensing data.
Claims15
A sensing device, comprising:
- a sensing pad that is a touch screen;
- and
- a control module,
- wherein the sensing pad comprises:
- a plurality of pressure measuring units arranged in a matrix and configured to measure pressure applied by loads of both feet;
- a plurality of transmission lines arranged in a column direction of the matrix and configured to provide a drive pulse to the plurality of pressure measuring units, in response to a setup signal from the control module;
- and
- a plurality of reception lines arranged in a row direction of the matrix and configured to receive a plurality of plantar pressure data having an analog state, from the plurality of pressure measuring units,
- wherein each pressure measuring unit of the plurality of pressure measuring units is electrically connected to a crossing point of one transmission line of the plurality of transmission lines and one reception line of the plurality of reception lines, and
- wherein the control module is configured to:
- receive the plurality of plantar pressure data having a digital state, converted from the plurality of plantar pressure data having the analog state;
- generate a plantar pressure data matrix obtained by aligning the plantar pressure data depending on coordinates of the pressure measuring units, each of which is connected to the crossing point of one transmission line of the plurality of transmission lines and one reception line of the plurality of reception lines;
- obtain first maximum data having a maximum value in n rows and second maximum data having a maximum value in m columns, on the basis of target data of the n rows and the m columns in the plantar pressure data matrix;
- determine one of the first maximum data and the second maximum data as reference data and calculate a unique reference value based on the reference data;
- and
- determine whether the target data is noise based on the unique reference value.

A method for processing sensing data, performed by a sensing device having a sensing pad that is a touch screen, and a control module, the method comprising:
- measuring pressure applied by loads of both feet, by a plurality of pressure measuring units of the sensing pad, arranged in a matrix;
- providing a drive pulse to the plurality of pressure measuring units, in response to a setup signal from the control module, by a plurality of transmission lines arranged in a column direction of the matrix;
- receiving a plurality of plantar pressure data having an analog state, from the plurality of pressure measuring units, by a plurality of reception lines arranged in a row direction of the matrix,
- wherein each pressure measuring unit of the plurality of pressure measuring units is electrically connected to a crossing point of one transmission line of the plurality of transmission lines and one reception line of the plurality of reception lines;
- receiving, by the control module, the plurality of plantar pressure data having a digital state, converted from the plurality of plantar pressure data having the analog state;
- generating, by the control module, a plantar pressure data matrix obtained by aligning the plantar pressure data depending on coordinates of the pressure measuring units, each of which is connected to the crossing point of one transmission line of the plurality of transmission lines and one reception line of the plurality of reception lines;
- obtaining, by the control module, first maximum data having a maximum value in n rows and second maximum data having a maximum value in m columns, on the basis of target data of the n rows and the m columns in the plantar pressure data matrix;
- determining, by the control module, one of the first maximum data and the second maximum data as reference data and calculating, by the control module, a unique reference value based on the reference data;
- and
- determining, by the control module, whether the target data is noise based on the unique reference value.
