中文摘要：

为了及时获取地震现场的震情与次生灾情信息，提出了一种新型的分布式采集系统。该系统由微处理器系统与地震烈度，GPS，有毒气体，以及火灾等信息采集模块构成。地震烈度模块和GPS模块一起，用以获取地震的时间、位置和强度等要素信息；有毒气体模块和火灾模块用于监测有毒气体泄漏和火灾。Modbus现场总线的引入，将各个信息采集模块与微处理器系统相连，构成了地震现场的分布式综合信息采集系统。实验结果表明：该综合采集系统能够及时获得地震现场震情和次生灾情信息，满足地震应急救援的信息需求。

英文摘要：

To master the information of earthquake and secondary disaster in time, a new on-site distributed acquisition system was presented. It was composed by a microprocessor system and some data acquisition modules, such as earthquake intensity module, GPS module, toxic gas module, and fire module. Both the earthquake intensity module and the GPS module were used to obtain time, position and intensity information of the earthquake. Mean while, the toxic gas module and the fire module were employed to detect leakage of toxic gases and fire. By the introduction of Modbus, all these data acquisition modules were jointed to the microprocessor system, and an on- site distributed and integrated acquisition system was built. The results showed that it could acquire the data of earthquake and secondary disaster in time, and could meet the on-site data acquisition needs for earthquake emergency rescue.
