Research On Wireless Monitoring System Of Omnidirectional Lower Limbs Rehabilitative Robot

With global aging deeply and patients with growing lower limb dysfunction, based on the project of Liaoning Provincial Natural Science Foundation"Research on omnidirectional mobile lower limb rehabilitation training robot and active rehabilitation control strategy", this thesis studies the wireless monitoring system of a lower limb rehabilitation training robot.Medical rehabilitation needs to send, handle and analysis patients'all kinds of important physiology information in time and accurately, which can help physicians make diagnosis to patients. In modern systems, signals tare transmitted in wired form. This form influences patients'normal activity, so it can hardly monitor comprehensively for a long time and make patients nervous. It leads to system getting wrong monitored data. Using wireless network transmitting in short distance may overcome defects above. Solution from this thesis may be used in nursing homes, gymnasium, hospital ward and so on. Users master patients'physiology information and health index.This thesis analyzes the situation of wireless monitoring system using in different fields, according to lower limbs rehabilitative training theory and using omnidirectional robot as platform, designs a new monitoring system for patients with lower limbs'obstacle. System uses star network communication protocol, so it realizes monitoring in time patients sporting information by using wireless sensors. With taking receiving and sending chip nRF24L01 as core and combining digitization sensor technology, this thesis designs a system for collecting acceleration parameter. The system has several advantages such as small volume, less power consumption, wireless transmitting and so on. Data are send through wireless receiving and sending chip, then input computer by micro control unit. Finally computer displays data through windows and stores it.
