摘　　要：针对Windows下MDSL(多通道同步数字记录仪)系统耦合度高,稳定性和实时性不够理想的缺陷,本文提出了新的系统架构和设计.该设计基于Linux操作系统(2.6内核),采用了多进程方式降低系统耦合度,提高系统可靠性,并采用双机冗余和守护进程等设计保证系统稳定性,同时采用了多线程管理方式实现远程控制单元.实践表明,新系统拥有更好的可靠性以及可维护性.Since Windows based MDSL system has defects like high coupling, relatively not stable and weak real-time, this paper puts forward a new system structure and design. Based on the Linux operat- ing system （2.6 kernel） ,this design uses a multiprocessing mode to reduce the system coupling, improve the system reliability, and ensure the stability of the system by using designs like dual machine redun- dancy and daemon process, and using the multi-threaded mode to process command so as to realize the remote control unit. The practice shows that the new system has better reliability and maintainability than the old one.
