太原理工大学硕士研究生学位论文DESIGN AND IMPLEMENTATION OF THE DI SASTERⅥ懂ATHER、7＼，ARNING TERMINALABSTRACTChina iS one of the contries which are vulnerable to natural disasters． Especially in recent years，China frequently suffers the ravages of naturaldisasters，such as floods，droughts，windstorms and snows by the global weatherwarming，which cause tremendous losses to people and are increasingly frequent and more and more serious．Because China is a huge geographical country,a dedicated weather warning system has not been established in urban and ruralareas at present．People forecast the weather disasters only through television， radio and other forms of weather warning in specific areas．We read a large amount of technical information and develop a complete set of technicalsolution．By existing mobile radio communication network and the local broadcasting system，we have realized the disastrous weather broadcasting and warning in countryside areas which are backward in telecommunication．Based Oil the disaster weather warning，this paper introduces a disaster weather warning terminal based on ARM embedded system，and discusses the structure of embedded systems by designing of the disaster weather warning terminal．The area of research involves embedded hardware design，the designof application software，transfer technology based on USB2．0 and other fields．III太原理工大学硕士研究生学位论文The broadcasting system sends the disaster weather warning information in form of SMS or voice；the terminal receives the warning weather information on time． when SMS is received，the terminal automatically opens to the local broadcasting system，plays the voice of the warning weather information，and opens the outdoor LED display which shows that warning information．Inaddition，the terminal can also download the information from PC by USB2．0interface．The author designs a part of hardware circuit and most of software，which includes the following：1．The hardware circuit of disaster weather warning terminal and the embedded opera
