Embodiment 1

[0027] Example 1, user Jia, male, 56 years old, weight 70KG, height 160CM, hemiplegic. During the rehabilitation training process, the "normal" step length of the diseased foot is 30-55CM, the step length before the disease is 20-40CM, the single-step time of the diseased foot is 9S, and the normal foot is 0.8S. Install tension sensors at the left front, left rear, right front, and right rear positions at the connection between the frame and the weight-reducing sling, and set the fall judgment threshold of the tension sensor to 171.5N. When any value of any of the four tension sensors is greater than 171.5N, The feedback signal of the main control board is "1" (note: the fall condition is met), otherwise the feedback signal is "0"; the photoelectric sensors are arranged in 7 groups equidistantly at intervals of 10cm from the user's initial standing position along the walking direction, when the second group of photoelectric sensors is in the When the detection signal is contin...

Abstract

The invention relates to a human lower limb rehabilitation training robot with intelligent safety protection, and belongs to the technical field of medical equipment. A transmitter emits light beams constantly to a receiver by pointing the receiver. The emitted light is either received by the receiver or blocked by a to-be-tested object. The receiver converts the received light signals into electrical signals. A detection circuit is used for detecting the electrical signals outputted by the receiver, filtering out the impurities to obtain effective signals and transmitting the effective signals to a main control board. The optoelectronic inspection method has the advantages of being high in precision, fast in response, capable of achieving the non-contact effect and the like. The detectable parameters are abundant, the sensor structure is simple, the mechanism is flexible and the size is small. The main control board fuses the two types of information collected from both a tensile force sensor and a photoelectric sensor by using program algorithms for falling judgment. The two types of signals from both the photoelectric sensor and the tensile force sensor are fused for the judgment, therefore the accuracy of the judgment is increased, particularly for the falling judgment, and the safety performance of the robot is enhanced.

Description

technical field [0001] The invention relates to a human lower limb rehabilitation training robot with intelligent safety protection, which belongs to the technical field of medical equipment. Background technique [0002] At present, rehabilitation robots have been widely used in rehabilitation nursing, rehabilitation wheelchairs, rehabilitation manipulators, artificial limbs, etc., which not only promotes the development of rehabilitation medicine, but also drives the development of new technologies and new fields in related fields.
