基于DSP的地震测试预警系统设计
|
摘要
地震是一种危害较严重的自然现象,对天然地震信号进行准确检测并对采集到的信号进行有效的分析和处理,以尽可能地减少地震自然灾害对人类造成的损失。为了准确地测量地震并给予预警,研制了以TMS320F2812 DSP为控制核心的地震测试预警系统。本系统传感器选用ADXL330加速度传感器,能够准确测量三维坐标下的各个方向的加速度分量,根据采集到的数据能够准确判定地震烈度等级并通过液晶屏显示,在地震时能够及时的语言报警,采集数据能够存入外扩存储器在需要的时候能通过USB接口读出。
Earthquake is a kind of very harmful natural phenomenon. It is necessary to detect natural seismic signal accurately , analyze and process the collected signals effectively, as far as possible to reduce the loss that earthquake create to human beings. To detect the earthquake rapidly and accurately and give alarm accordingly, a detecting and pre-warning system based on DSP is designed. ADXL330 sensor is used in the system. It can measure accurately on each direction. It can determine the seismic intensity levels accurately and display on the LCD . During an earthquake, you can hear voice alarm and read the collected data through USB
