Embodiment Construction

[0029] like figure 1 shown. The six-component supporting force test bench 1 and the flexible array sensor 2 are structurally integrated, and are respectively used for the detection of contact force and contact form to form a complete tactile information acquisition device. Four three-dimensional force sensors 1-3 are installed on the upper splint 1-1, between the lower splints 1-2, between the upper and lower splints 1-1, 1-2 and the three-dimensional force sensor 1-3 are fastened and connected by screws. In one implementation, the integrated signal conditioning acquisition circuit 3 is installed in the body of the gait tactile information measuring device. In other implementations, the integrated signal conditioning acquisition circuit 3 can be externally connected to the haptic information through the connector / signal line. Get the device body connection. The tactile signal sensed by the body of the gait tactile information measuring device is amplified, filtered and prepr...

Abstract

The invention discloses a device and method for measuring gait touch information. The device for measuring gait touch information comprises a computer, a six-component holding power test board and an integral signal conditioning and acquiring circuit. The measuring method comprises the following steps of: acquiring signals of a strain sensing sensor and a flexible array sensor in the six-component holding power test board by using the integral signal conditioning and acquiring circuit and transmitting the signals to the computer; and extracting corresponding parameters by using a test and analysis software module of the computer. An integral instrument is designed, and detection mechanisms of vector contact force information and contact state information are unified in the aspects of a physical layer, a hardware layer and a data layer, so that complete foot region touch original information is directly provided.

Description

technical field [0001] The invention relates to the field of biological feature recognition, in particular to a gait tactile information measuring device and a measuring method. Background technique [0002] Walking (including standing and running) is the most common human movement phenomenon, and it is an important research content of sports biomechanics. In the fields of sports research, biomechanical engineering, and medical rehabilitation, it is often necessary to accurately know the force / moment in three directions between the sole of the human body and the ground, the contact status of the sole of the foot and the ground, and all the positions of the sole of the foot when the human body is walking or exercising. The distribution of stress is expected to obtain scientific basis for gait analysis, sports research, sports training guidance, medical research, and residual rehabilitation training guidance. The three-dimensional force plate and the plantar pressure distribu...
