Embodiment Construction

[0009] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0010] see figure 1 , the FPGA-based lower limb rehabilitation device in the embodiment of the present invention includes a mechanical system, a photoelectric encoder, a photocoupler, an FPGA chip, a USB interface chip, a PC host computer, a power supply, and a crystal oscillator.

[0011] The photoelectric encoder is installed on the mechanical system, which can collect the displacement data of the lower limbs, and transmit the data to the photocoupler through the input port of the photocoupler.

[0012] The photoelectric coupler is used to reduce the digital signal voltage output by the photoelectric encoder, so that the voltage matches the FPGA chip.

[0013] The FPGA chip is connected with the output port of the optocoupler. The FPGA chip selected in this embodiment is a Cyclone III EP3C series device of Altera Company, and its model is EP3C16Q240...

Abstract

The invention discloses FPGA (Field Programmable Gate Array) based lower limb rehabilitation equipment and belongs to the technical field of medical equipment. The FPGA based lower limb rehabilitation equipment is used for solving the defect that the lower limb rehabilitation training for paralytic patients is difficult. The FPGA based lower limb rehabilitation equipment comprises an optical-electricity encoder, a photoelectric coupler, an FPGA chip, a USB (Universal Serial Bus) interface chip, an upper computer, a power source and a crystal oscillator. The FPGA based lower limb rehabilitation equipment has the advantages of collecting data of a patient during lower limb rehabilitation training in real time, collecting patient physical state index data and providing accordance for later rehabilitation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an FPGA-based lower limb rehabilitation device. Background technique [0002] Paralysis is a common disease, especially in the majority among the elderly, especially patients with paralysis of the lower limbs, who cannot take care of themselves in daily life due to inconvenience in walking, and must be accompanied by someone to look after them. During the rehabilitation training of patients with paralysis of the lower extremities, it is necessary to use some rehabilitation equipment to recover slowly through regular exercise. However, in the process of rehabilitation training, most rehabilitation equipment can only perform mechanical rehabilitation training and cannot collect paralyzed patients. Indicator data of physical condition during rehabilitation training. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, ...
