针对传统监控系统监控对象单一、网络服务不完善、智能化程度不高等问题,设计并实现了一种下位机以i.MX53处理器为核心,嵌入式Linux作为嵌入式操作系统；上位机采用LabWindows/CVI开发,上下位机遵照自拟的网络通信协议通信的远程监控系统.采用Linux下进程间通信、LabWindows/CVI与MySQL数据库通信、多线程和基于ActiveX生成报表等技术,实现了信号采集、报文传输、数据存储和实时显示等功能.测试结果表明,该系统用户界面仿Win8风格,远程视频监控平均延时1.45 s,报警正确率达98.2％,具有一定的推广和使用价值.%The traditional monitoring system was only applicable to a monitoring object,poor in network services and not high degree of intelligence.In order to solve these questions,a remote monitoring system based on i.MX53 as the core microcontroller was designed and realized.Linux was used as its operating system in the lower computer part,and LabWindows/CVI was used as development platform in the upper computer part.The two parts was communicated through the private network communication protocol.Several technologies were adopted such as inter-process communication under the Linux,MySQL database communication,multithread technology,and generating data report based on ActiveX etc.The system realizes the signal collection,message transmission,data storage and real-time display and other functions.Test results show that the system has imitation Win8 style of user interface,the average delay of 1.45 s in remote control,and alarm accuracy of 98.2％,so it has some practical value.
