摘要 随着坐姿不良引起的疾病问题日渐增多，人们纷纷将目光集中于如何防止坐姿不良这一问题之上。无论是从座椅的设计，还是从自身的习惯入手，坐姿压力测量都是解决问题的理论依据之一。现代社会，坐姿不良被证明为很多疾病的起因，例如脊柱侧弯， 颈椎病，尾骨疼痛等，尤其是青少年正处于身体成长期，坐姿不良的坏习惯会对青少年的身体健康产生极大的危害。人体坐姿压力测量系统能很好的预防坐姿不良带来的危害，但是目前国内关于这方面的研究相对较少。49452
本文通过对国内外人体压力测量系统的研究，自制了一个基于导电硅橡胶的坐姿压力测量系统，并阐述了该坐姿压力测量系统的软硬件结构以及工作原理。通过该系统显示的压力着色图可以很轻松的对坐姿压力中心的位置以及坐姿压力的分布情况做出判别，指导被测试者正确的坐姿。

Title Design Of A Sitting Position Pressure Measurement System
Abstract
With the increasing number of diseases caused by poor sitting posture, people have focused on the problem that how to prevent poor sitting posture. Whether it is based on the design of seats , or based on people's own habits, sitting pressure measurement is one of the theoretical basis for solving the problem. In modern society, poor sitting postures have been proved to be the cause of many diseases, such as scoliosis, cervical spondylosis, coccyx pain. Especially for those juvenile who are in the key period of their body growth, poor sitting posture for a long time will lead to adolescents with serious illnesses. The pressure measurement system of the human body sitting posture can prevent the harm caused by bad posture, but the domestic research on this field relatively fall behind. The research of domestic and foreign body pressure measurement systems have been done and a sitting pressure measuring system based on conductive silicone rubber has also been set up .
This article expounds the structures and working principles of the software and hardware of this sitting posture pressure measurement system. Through the pressure coloring map showed by the system, it can be easy to make a judgment of the position of the pressure center of the sitting posture and the distribution of sitting pressure, and guide the correct sitting habits of people .
Keywords：Sitting pressure, Conductive silicone rubber ，Sensor array, Pressure display
