The Design And Implementation Of Student Physique Monitoring Embedded System

Physical health more and more get the attention of people,especially small and medium-sized student's physique condition.In the field of the physique monitoring,although countries constantly increase investment in human and financial resources,but still can't meet the demand of the market.Traditional constitution monitoring equipment has some limitations,such as single function,cumbersome equipment and learning time cost is higher,and cannot well adapt to the current market demand,prompting physique monitoring ways,methods and innovation.With the mature of mobile Internet,people began to widely used with the Android,iOS,and other operating system of the equipment.In the field of traditional embedded,free,open source Android operating system,more and more popular,start by using Linux to use the Android operating system.The constitution monitoring embedded system development,mainly including upper machine and lower machine two parts.PC architecture A9 as core board,expanded the corresponding module,mainly for the volume control of the machine,time setting,and the lower machine for wireless communication,RFID data reading and writing,and laser barcode reading and testing process control,results and broadcast,etc.Under a machine adopts MSP430F149 development board,is mainly used for test data collection,preservation and wireless communication with PC,and in the online or stand-alone mode,all can complete testing capabilities.PC in the Android environment,use Java language development,mainly completed the PC system interface design,design of serial port communication,speech synthesis,functional design,and data storage design.Under a machine adopts C language development,mainly completed.the interface development,data collection and data save,etc.Upper machine and lower machine have colour touch screen,easy to operation and data is read.Between upper machine and lower machine adopt the way of wireless data transmission,use a polling design way to ensure proper data transmission.In this design,mainly around the sit-ups,pull-ups,rope skipping and so on to carry on the design.Finally,the overall system debugging,main operation interface and the debugging result are given,good running effect were obtained.
