| With the rapid development of Internet technology,computer performance such as board level,chip level and even nano scale has been continuously improved,a new demand for wearable computers comes into being.Wearable technology pursuits more convenient,more intelligent,more people-oriented in the use of computer,and after the integration of miniature electronic equipment,by the user in the clothes or wear in the body to perceive the corresponding biological data or positioning data,has the advantages of controllable operation,free movement,rich sensors and wide prospect.Involving sports and health,networking,human-computer interaction,high efficiency,energy and many other fields,in recent years led the new round of explosive growth of related scientific and technological enterprises.Intelligent running shoes as a number of wearable devices in a constantly changing paragraph,accept consumer favour,but in the use of existing in the process of running shoes products on the market found that running shoes intelligent effect is prominent,realtime backup state of user's location is not sensitive,lack of monitoring campaigner biological data and text localization,the battery is used up big problems such as still unable to effectively put an end to.In this paper,on the basis of the design of a multifunctional intelligent running system,the movement of biological data collection,personnel positioning information acquisition,backup server and client mobile communication and low power consumption in many aspects of functional integration,sensor distribution with reasonable running space,for the safety of future intelligent wearable devices of a novel solution.The design of the system is divided into five parts.The first is the design of hardware,the shoes are smaller in size,the foot is limited,so using self-made PCB sole plate to meet the demand,the main control chip uses STM32F103RBT6 model,temperature,pressure,peripheral circuit containing three vibration sensor module,six axis acceleration gyroscope and GPR/GPRS positioning module module based carrier coordination between modules and circuit,completed the acquisition of human motion data work.The part of the algorithm,six axis acceleration gyroscope to measure the body running state needs four yuan and the number of attitude calculation,the Euler angle formula in fourdimensional rotation axis in use,through the DMP program design to realize the distance,frequency and stride of acquisition,and the results displayed on the mobile phone APP client.The software is composed of the sensor,the gyroscope call display module,the Android APP interface UI and the programming module and the server Socket programming module.Serial receiving process using Bluetooth,mobile phone client developed shose.apk Android applications,monitoring acquisition sole sensor information,positioning Baidu map calls and track drawing,can accurately find the location of Information Science College of Chengdu University of Technology,and completed the client server,message forwarding,user longitude and real-time information are reliable protection.The deployment of the system,including the deployment of software and hardware deployment,software including uC/OS-II operating system transplantation,GPS,GPRS initialization debugging and data configuration,hardware and electronic equipment according to the actual size of the volume of the shoes,running shoes of structure,design a reasonable running transverse and longitudinal hardware deployment diagram.System testing,comply with development sequence,from regression testing,unit testing to system integration testing,including running shoes,APP display,Android terminal receiving client communication connection,Baidu maps,users running route display and verification of GPS/GPRS positioning,through iteration and debugging,the system is stable,good operation,low power consumption low,although there are some shortages and need to be improved,but overall,The design requirements of multifunctional intelligent running shoes are realized. |
