Embodiment 1

[0084] The first embodiment provides a plantar pressure detection mechanism, which can collect pressure signals of various parts of the human foot. The control system can use the pressure signal collected by the mechanism for subsequent processing, such as judging the movement of the human foot, so as to control the actuator to perform corresponding actions.

[0085] Please refer to figure 1 , the plantar pressure detection mechanism includes:

[0086] support layer 100;

[0087] A pressure sensor (the pressure sensor is a conventional choice, not shown in the figure), the pressure sensor is installed on the support layer 100;

[0088] And the cover layer 200 for being arranged on the sole of the human body, the cover layer 200 includes the toe area A for spreading the pressure applied to the toe part of the human body, and the arch area A for spreading the pressure applied to the arch part of the human body B and the heel area C for spreading the pressure exerted on the he...

Embodiment 2

[0107] The second embodiment provides a gait recognition method, which is used to recognize the gait of a human body, and then output a corresponding command to the actuator, so that the actuator can cooperate with the gait of the human body.

[0108] Please refer to Figure 4 , the gait recognition method includes:

[0109] Definition step: define the pressure state corresponding to the toe position, the arch position and the heel position of the sole under each gait phase, and the pressure state is divided into a high pressure state and a low pressure state;

[0110] Signal acquisition step: Acquire the pressure detection signals of the toes, arches, and heels at the same time;

[0111] Converting step: converting the obtained pressure detection signal into a digital signal representing a high pressure state or a low pressure state;

[0112] Judgment step: compare the acquired pressure states of the toes, arches, and heels with the pressure states defined by each gait phas...

Embodiment 3

[0162] Embodiment 3 provides a gait recognition device corresponding to Embodiment 2, including:

[0163] The definition module is used to define the pressure state corresponding to the toe position, the arch position and the heel position of the sole under each gait phase, and the pressure state is divided into a high pressure state and a low pressure state;

[0164] The signal acquisition module is used to acquire the pressure detection signals of the toes, arches and heels of the soles of the feet at the same time;

[0165] A conversion module, configured to convert the obtained pressure detection signal into a digital signal representing a high pressure state or a low pressure state;

[0166] The judging module compares the pressure state of the toe, arch, and heel with the pressure state defined in each gait phase at the same time. If it is consistent with the result of a certain gait phase, it is judged that the current state Gait phase; if it is different from all gait...

Abstract

The invention discloses a gait recognition method and device. According to the method and the device, firstly the corresponding pressure state of the pelmatic toe parts, the arch parts and the heel parts under each gait phase is defined; and then the pressure state of the toe parts, the arch parts and the heel parts of the same time is acquired. According to the recognition method, the state of each part is divided into the high pressure state or the low pressure state, and the acquired pressure state of the toe parts, the arch parts and the heel parts of the same time is compared with that of the defined gait phase so that the gait phase of the moment can be judged and the more accurate judgment result can be acquired.

Description

technical field [0001] This application relates to the field of human exoskeleton robots, especially the recognition of human gait. Background technique [0002] Human gait is an important aspect of human motion research, involving the fields of sports rehabilitation and robot control, especially in the control of mechanical exoskeleton robots, the accurate recognition of human gait is particularly important. Mechanical exoskeleton technology is a current hotspot. By providing extra power to the human body, it can enhance the human body's motor function and improve the human body's motion ability. It can be used in military and industrial fields; on the other hand, it can also be used in the medical field. It can assist patients with lower limb dysfunction to carry out rehabilitation training. [0003] In the control of human exoskeleton robots, there are two main ways to identify the gait of the lower limbs: based on electromyographic signals or based on plantar pressure s...
