【摘要】：隨著我國國民經(jīng)濟(jì)的發(fā)展,社會壓力的遞增,工作時間占據(jù)人們生活比重逐年上升,這直接導(dǎo)致了我國久坐人群數(shù)量的持續(xù)性擴(kuò)大。大量研究數(shù)據(jù)表明,久坐的生活方式已經(jīng)成為一個全球性的公共衛(wèi)生問題,對人類的生活產(chǎn)生了嚴(yán)重的負(fù)面影響。研究表明,不良的坐姿會引發(fā)很多疾病。當(dāng)人體長期處于坐姿狀態(tài)時,受力不平衡可能導(dǎo)致坐瘡和一些腰椎疾病如脊柱損傷、腰椎間盤突出等。因此研究人坐姿狀態(tài)下壓力分布是非常必要的。本文設(shè)計(jì)的面向久坐人群的坐姿體壓采集系統(tǒng)是預(yù)防上述疾病的有效工具,該系統(tǒng)可對人體坐姿下的壓力中心進(jìn)行測量、分析,以期指導(dǎo)人們正確的坐姿,幫助人們預(yù)防由于坐姿不平衡而產(chǎn)生的疾病。該系統(tǒng)主要由三大部分組成:壓力數(shù)據(jù)采集模塊、移動端數(shù)據(jù)接收和處理模塊、服務(wù)器端數(shù)據(jù)存儲和分析模塊。本文首先對坐姿理論進(jìn)行闡述,解釋了久坐造成病理學(xué)影響與心理學(xué)影響的機(jī)制,而后進(jìn)行文獻(xiàn)綜述,闡述了坐姿壓力分布研究現(xiàn)狀、坐墊設(shè)計(jì)研究現(xiàn)狀,作為本位后續(xù)設(shè)計(jì)的參考依據(jù)。對久坐人群進(jìn)行定義與群體劃分,提出面向久坐人群的坐姿體壓采集系統(tǒng)方案,并重點(diǎn)對各個模塊的功能、設(shè)計(jì)和實(shí)現(xiàn)進(jìn)行了詳述。最后,本文對系統(tǒng)進(jìn)行了展示,并使用該坐墊對正常人進(jìn)行了實(shí)例測試,系統(tǒng)可對人體的坐姿情況進(jìn)行簡單的判別,測試結(jié)果對比效果明顯、合理。分析和實(shí)驗(yàn)結(jié)果表明:本文設(shè)計(jì)的坐墊方案合理可行,能實(shí)現(xiàn)人坐姿狀態(tài)下壓力中心的動態(tài)、實(shí)時測量。
[Abstract]:With the development of our national economy and the increasing social pressure, the proportion of working hours occupying people's life is rising year by year, which directly leads to the sustained expansion of the number of sedentary people in our country. A great deal of research shows that sedentary lifestyle has become a global public health problem, which has a serious negative impact on human life. Studies have shown that poor posture can cause many diseases. When the body is sitting for a long time, the force imbalance may lead to sit sore and some lumbar diseases such as spinal injury, lumbar disc herniation and so on. Therefore, it is necessary to study the pressure distribution in sitting position. The body pressure collection system designed in this paper is an effective tool to prevent the above diseases. The system can measure and analyze the pressure center under the sitting position of human body, in order to guide people to sit correctly. Help people prevent diseases caused by the imbalance in their posture. The system consists of three parts: pressure data acquisition module, mobile data receiving and processing module, server data storage and analysis module. In this paper, the theory of sitting posture is first expounded, the mechanism of pathological and psychological effects caused by sitting is explained, and then literature review is carried out, and the present situation of research on pressure distribution of sitting posture and the design of seat cushion is described. As the reference basis for the future design of the standard. This paper defines and divides the group of sedentary people, puts forward the system scheme of sitting posture pressure collecting system for sedentary crowd, and focuses on the function, design and implementation of each module. Finally, the system is displayed in this paper, and the seat cushion is used to test the normal person. The system can judge the sitting posture of human body simply, and the result of the test is obvious and reasonable. The results of analysis and experiment show that the cushion scheme designed in this paper is reasonable and feasible, and can realize the dynamic and real-time measurement of the pressure center under the human sitting posture.
