基于eCos的海底地震仪嵌入式软件系统

The embedded software system of ocean bottom seismometer based on the eCos

针对海底地震仪在文件存储,数据通信等方面的观测要求,在海底地震仪的研制中引入了eCos(EmbeddedConfigurable Operating System)系统,开发了基于该系统的具有数据采集、文件存储、仪器状态控制、网络数据通信、无线通信等功能的海底地震仪控制软件.本文在对海底地震仪的系统结构和工作模式作简要说明的基础上,重点介绍了eCos系统构建过程,海底地震仪控制软件的结构,指出该软件系统可有效地提高海底地震仪观测系统运行的稳定性和可靠性.

Applying the eCos operating system we develop the OBS（ocean bottom seismometer）＇s control software to meet the observational requirement in file storage and data communication.The software has following functions：data acquisition,file storage,controlling instrument working status,network communication,and wireless communication and so on.The OBS hardware structure and working mode are introduced,the method of building eCos,and the structure of OBS control software are presented in detail in the paper.This software system can improve the stability and reliability of OBS effectively.
