毕业设计（论文）-基于单片机的电阻式烟雾传感器报警系统设计_精品.doc

摘要 随着“信息时代”的到来，作为获取信息的手段传感器技术得到了的进步，其应用领域越来越广泛，对其要求越来越高，需求越来越迫切。传感器技术已成为衡量一个国家科学技术发展水平的重要标志之一。因此，了解并掌握各类传感器的基本结构、工作原理及特性是非常重要的。本文利用单片机结合技术而开发设计了这一可燃气体敏感元件While “information age” the arrival, obtained the remarkable progress as the gain information method - - sensor technology, its application domain is more and more widespread, is more and more high to its request, the demand is more and more urgent.The sensor technology has become weighs one of national science and technology level of development important symbols.Therefore, understood and grasps each kind of sensor the basic structure, the principle of work and the characteristic is extremely important. In order to enhance to the sensor understanding and the understanding, in particular to the smog sensor thorough research as well as its usage and the use, based on practical, widespread and the model principle has designed this system.This article used the monolithic integrated circuit union sensor technology to develop has designed this smog supervisory system.。 The present paper take leaves the minor smog sensor and the monolithic integrated circuit technology unifies as the core and with other electronic technology, designs one kind of technical level good smog alarm apparatus.In which selects the 2M007 semiconductor resistance type smog sensor realization smog the examination, has the sensitivity high, responds, the antijamming ability quickly strong and so on the merits, moreover the price is inexpensive, the service life is long.Selects the STC12C5410AD monolithic integrated circuit, its conformity A/D transformed, the hardware multiplier, resources and so on hardware PDM keyer, has high speed, low merits and so on power loss, ultra strong antijamming, is the present similar technology neutral price quite high product. May realize the acousto-optics take the STC12C5410AD monolithic integrated circuit and the 2M007 semiconductor resistance type gas sensor as the core design smog alarm apparatus to report to
