時間:2019-04-22 13:40來源:畢業論文
針對所選擇的傳感器,設計了相應的驅動電路以及相應的硬件編碼電路,并進行實驗驗證。進行了實際的坐姿壓力測量的實驗,對幾種傳感器進行對比研究,改進和優化軟硬件設計

在我們的一生當中有很長的一段時間是處于坐姿的狀態的,如果我們不注意良好的坐姿的養成那么就會影響我們的身體骨骼的發育,隨著坐姿不良引起的疾病問題日漸增多,人們紛紛將目光集中于如何防止坐姿不良這一問題之上。無論是從座椅的設計,還是從自身的習慣入手,坐姿壓力測量都是解決問題的理論依據之一。現代社會,坐姿不良被證明為很多疾病的起因,例如脊柱側彎, 頸椎病,尾骨疼痛等,尤其是青少年正處于身體成長期,坐姿不良的壞習慣會對青少年的身體健康產生極大的危害。同樣的,沒有一個良好的坐姿也會影響我們的外在形象,因此坐姿的養成對于我們而言就顯得特別的重要。通過查閱相關資料,關于坐姿壓力測量的相關設備在國內還相對薄弱,在國外比較成熟。在本次項目中分析并且選擇了幾種不同類型的測壓傳感器,并對傳感器陣列進行了優化與布置。針對所選擇的傳感器,設計了相應的驅動電路以及相應的硬件編碼電路,并進行實驗驗證。進行了實際的坐姿壓力測量的實驗,對幾種傳感器進行對比研究,改進和優化軟硬件設計。lf0043

   Abstract
    In our life, has a long period of time is in a state of posture, if we do not pay attention to the cultivation of good posture, it will influence the development of our body's skeletal, with poor posture disease problems caused by the increasing, people have focused on how to prevent bad posture on the issue. Whether it is from the seat of the design, or from their own habits, sitting pressure measurement is one of the theoretical basis for solving the problem. In modern society, poor posture is proved to be the cause of many diseases, such as scoliosis, cervical spondylosis, coccyx pain, especially teenagers are in the growth stage, the posture bad bad habit will produce great harm to young people's health. Similarly, without a good sitting posture will affect our external image, so the form of sitting posture is very important for us. Through access to relevant information, on the sitting pressure measurement of the relevant equipment in the country is still relatively weak, relatively mature in foreign countries. In this project, we analyze and select several different kinds of pressure sensor, and optimize and arrange the sensor array. According to the selected sensor, the corresponding driving circuit and the corresponding hardware coding circuit are designed, and the experimental verification is carried out. In the experiment, the experimental measurement of the sitting posture is carried out, and several kinds of sensors are compared and studied to improve and optimize the software and hardware design.
