摘要
自主式水下机器人(以下简称AUV)数据采集与管理系统(以下简称DCAM)利用多线程同步和通信机制实现了多串口数据采集,利用循环缓存区和存储转发的机制实现了将数据通过网络定时传送给工控机并将数据在本地保存。最后采用白盒测试的方法对该系统进行了测试并利用Musa执行时间模型对该系统进行了定量估计和预测其可靠性,预测结果显示该系统可以达到预计要求。
The data logging and management system (DLAM) of the autonomous underwater vehicle (AUV) running on the on-board PC/104 module uses the synchronization and communication mechanism by using multi-threading to implement the function of the collection of data from different devices through multi-serial-port card,as well as the function of enveloping and transmitting the data to the on-board Industrial PC (IPC) via Ethernet and the function of managing and recording the data locally.Finally the white-box testing method is employed to test the system,and Musa execution time model is used to estimate the reliability.The result of the estimation shows that the system achieves the expected requirement.
