【摘要】：体质健康状况越来越受到人们的关注,尤其是中小学生的体质状况。在体质监测领域中,虽然国家不断加大人力、财力的投入,但依旧不能满足市场的需求。传统的体质监测设备具有一定的局限性,如功能单一、设备笨重和学习时间成本高等,并不能很好地适应目前的市场需求,这促使体质监测的方式、方法也不断创新。伴随着移动互联网的日渐成熟,人们开始广泛使用具有Android、iOS等操作系统的设备。在传统的嵌入式领域,免费开源的Android操作系统,越来越受到欢迎,开始由使用Linux等转向使用Android操作系统。该体质监测嵌入式系统的开发,主要包括上位机和下位机两个部分。上位机以Cortex-A9作为核心板,扩展了相应的模块,主要实现设备音量控制、时间设定、与下位机进行无线通讯、RFID数据读写、激光条码读取以及测试的流程控制、结果保存与播报等功能。下位机采用MSP430F149开发板,主要用于测试数据的采集、保存和与上位机的无线通信,并且在联机或单机状态下,均可完成测试功能。上位机在Android环境下,采用Java语言进行开发,主要完成了上位机系统的界面设计、串口通信设计、语音合成功能设计以及数据存储设计。下位机采用C语言进行开发,主要完成了界面开发、数据采集以及数据保存等内容。上位机和下位机均具有彩色触控显示屏,便于操作和数据读取。上位机与下位机之间采用无线通讯的方式进行数据传输,利用轮询的设计方式确保数据正确传输。本次设计中,主要围绕仰卧起坐、引体向上、跳绳等项目进行设计。最后,对整体系统进行了调试,给出了主要运行界面和调试结果,取得了较好的运行效果。
[Abstract]:People pay more and more attention to the state of physical health, especially the physical condition of primary and middle school students. In the field of physique monitoring, although the state increases the investment of human and financial resources, it still can not meet the needs of the market. The traditional physique monitoring equipment has some limitations, such as single function, heavy equipment and high cost of study time, which can not adapt to the current market demand, which urges the way and method of physique monitoring to be innovated constantly. With the increasing maturity of mobile Internet, people begin to widely use devices with Android,iOS and other operating systems. In the traditional embedded field, the free and open source Android operating system is becoming more and more popular, and begins to change from using Linux and so on to using Android operating system. The development of the embedded system includes two parts: upper computer and lower computer. The host computer takes Cortex-A9 as the core board, expands the corresponding module, mainly realizes the device volume control, the time setting, the wireless communication with the lower computer, the RFID data reading and writing, the laser bar code reading and the testing flow control. Results the function of saving and broadcasting. The lower computer adopts MSP430F149 development board, which is mainly used for data acquisition, storage and wireless communication with the host computer. Under the environment of Android, the host computer is developed with Java language. The interface design, serial communication design, speech synthesis function design and data storage design of the host computer system are completed. The lower computer is developed by C language, which mainly completes the interface development, data acquisition and data preservation. Upper computer and lower computer have color touch display screen, easy to operate and read data. The data is transmitted by wireless communication between the upper computer and the lower computer, and the correct data transmission is ensured by the design of polling. This design, mainly around sit-ups, up-up, rope skipping and other items to design. Finally, the whole system is debugged, the main running interface and debugging results are given, and good results are obtained.
