Aiming at wide application of wireless monitoring system,the method of monitoring terminal based on embedded system S3C2410 and GPRS is presented.The paper describes the system's whole design methods and the characteristics of system and GPRS specifically,and gives a way on how to dial a number by internet based on embedded OS Linux completely.In addition,the system test method is introduced,and the test result indicates that the wireless monitoring terminal connected with Internet through GPRS can transmit data with the online host.According the experiment result,it can be concluded that the system runs stably,has a great improvement in expandable function,and has great application value.

The model of torpedo guidance system based on CAN is designed after the analyzed of CAN bus and its feasible application.In this paper the hardware & software of the design is presented in detail.The model completed the experimentation of torpedo depth control successfully,and confirmed that the CAN bus would be competent for torpedo guidance system.

μc/os-Ⅱ(embedded real-time OS)passes FAA safety certification,and has character of open source codes and is free in study.Realization of system modules such as kernel improvement,file system,TCP/IP protocol stack is discussed.This platform provides utilities forapplication based on μC/OS-Ⅱ and makes the work easier and faster.

This paper first introduce RTOS μC/OS-Ⅱ and LPC2119 chip,then presents a kind of new control strategy for torpedo control system.At last the paper indicates that method based on embedded technology is superior to the one used at present.
