嵌入式船舶数据记录仪监测系统设计与实现

以PC/104嵌入式工控机与PC机所组成的局域网为基础,在VC环境下,有效利用CSocket类和SQL数据库,开发基于TCP/IP协议、客户端/服务器模式的专门记录船舶装置长期运行且无人值守环境下的监测系统,完整、准确地记录船舶航行各装置工况。系统具有实时数据采集、远程数据传输、数据监测、数据查询等功能,并在文件传输过程中采用混沌加密算法保证数据信息安全。经过实际调试与运行,该记录仪运行稳定,实时性好,安全性高。

Design and Implement of the Embedded Ship Data Recorder Monitoring System

By means of the principle of CSocket and SQL database with ADO(Active Data Object),a monitoring system of Client/Server mode,based on TCP/IP protocol,was developed in VC 6.0 environment.Data of ship equipments in long-playing and unmanned watch circumstances were all-around recorded.It is possible to realize a series of data operations needed for safety monitoring,such as the real-time data collection,data displaying,long-distance data transferring,data searching,and using the chaos encryption algorithm to ensure the security of data while files were transferred.Results showed that the recorder runs stably and has good real-time ability and good security.
