沈阳建筑大学城市建设学院毕业设计（论文） 核准通过，归档资料。 未经允许，请勿外传！ 摘 要 本系统主要由单片机和 GTM900C 短信模块和防倾覆传感器组成，借助可靠、 成熟的 GTM900C 模块，以最直观的中文短消息直接把贵重物品的倾覆情况反映 到您的手机屏幕上。它采用防倾覆传感器进行检测，随着 MEMS 技术的发展， 惯性传感器件在过去的几年中成为最成功,应用最广泛的微机电系统器件之一。 当倾角传感器静止时也就是侧面和垂直方向没有加速度作用，那么作用在它上面 的只有重力加速度。重力垂直轴与加速度传感器灵敏轴之间的夹角就是倾斜角了。 GTM900-C 借用无线发送和接收、基带处理等功能，来实现无线数据传输和短信 收发任务。结合 AT89S52 单片机，外加串口电路，报警电路以及显示模块，设 计了防倾覆检测并报警的硬件系统变有形的传统防倾覆网为无形，给贵重物品倾 覆时的及时发现提供方便。传统的防倾覆系统非常复杂而且要把设备拆卸下来也 很麻烦，因此影响到了物品的便携性。本系统具有制作简单、成本低、安装方便、 防倾覆性能稳定等特点实现对贵重物品倾覆的及时监督，检测功能。 关键词；单片机；GTM900C 模块；防倾覆传感器 1 沈阳建筑大学城市建设学院毕业设计（论文） Abstract The system is mainly composed of a single chip computer and GTM900C SMS module and anti overturning sensors，By means of reliable, mature GTM900C module In the most intuitive Chinese short message directly to the valuables capsize reflected to your mobile phone screen. It adopts the anti overturning sensors were detected, with the development of MEMS technology, inertial sensing device in the past few years to become one of the most successful, most widely applied in MEMS device. When the inclination angle sensor static is lateral and vertical direction without acceleration, then acting on it is the acceleration of gravity. Gravity vertical shaft and the acceleration sensor sensitive axis is the angle between the inclined angle. GTM900-C uses the wireless sending and receiving, baseband processing function, to realize wireless data transmission and messaging tasks. Combined with AT89S52MCU, plus serial circuit, an alarm circuit and a display module, design of the anti overturn detecting and alarming system the physical change of the traditional anti overturning as intangible valuables, to overturn in convenience. The traditional anti overturning s
