The Design And Implementation Of Motor Recovery Oriented Wearable Wireless Sensor Network System

With the development of the acceleration of aging in modern society, limb motor dysfunction caused by cerebral and other diseases of the patients are increasing year by year. Modern rehabilitation medicine and its clinical research results show that through scientific rehabilitation training can restore the damaged limb function to a certain extent. In the rehabilitation process,real-time monitoring and evaluation of health status and effect of training physicians responding patients, so as to adjust the rehabilitation program in a timely manner. To overcome the lack of real-time monitoring and evaluation of traditional rehabilitation methods, a set of monitoring system is designed based on wireless sensor network technology. The main contents of this thesis are as follows:Firstly, according to the needs of the rehabilitation monitoring system, the monitoring of the movement track of patients in the process of sports training is carried out to determine whether the training program is trained. In the training process, the physiological parameters of the patients are monitored in real time;Secondly, according to the demand of wireless sensor network system, the design of wireless sensor node and gateway is reasonable. Sensors that satisfy the delay and precision of the system are required to realize the monitoring of the physiological parameters, and the size and weight of the sensor nodes are considered, the nodes try to make micro miniaturization; select control chip and chip communication right, normal communication system logic control and network; according to the characteristics of electromagnetic wave propagation in human peripheral the selection or design of the appropriate topology and communication protocol; drawing meet the high efficiency, high transmission rate, anti interference and other requirements of the sensor terminal node, the sink node circuit diagram, PCB and FPC chip communication; gateway selection meet system, gateway structure and reasonable design and PCB.Once again, the data processing algorithm, which satisfies the requirements of data processing, can be used to extract the physiological parameters and combine with the embedded system of wireless sensor network. Development of remote monitoring software and near end monitoring software based on Android system. Software requires a good operating interface, reasonable and effective data processing algorithms, and improve the function(communication, data display, etc.).Finally, the system debugging, monitoring is conducted on the experimenter. The experimental results show that the system has applicability and reliability, to meet the sports function rehabilitation training process, the physician of the patients need real-time monitoring of physiological parameters.
