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。
Aiming at the problems of single monitoring object, imperfect network service and low intelligence, the lower computer is designed and implemented with i.MX53 processor as the core and embedded Linux as the embedded operating system. The upper computer uses LabWindows / CVI development, the upper and lower computer in accordance with the proposed network communication protocol communication remote monitoring system. Using Linux inter-process communication, LabWindows / CVI and MySQL database communication, multi-threading and ActiveX-based report generation, it realizes the functions of signal acquisition, message transmission, data storage and real-time display. The test results show that the user interface of this system imitates Win8 style, the average delay of remote video monitoring is 1.45 s, and the correct rate of alarm is up to 98.2%, which has certain promotion and use value.
