摘　　要：随着继电保护领域嵌入式装置的程序复杂度日益增加,极易出现内存泄漏问题;如果不及时发现并解决,不仅将浪费大量宝贵的内存资源,还会导致系统崩溃和装置死机,造成不可估量的损失。为了解决这一问题,本文提出了一种面向嵌入式装置的远程可视化内存泄漏检测系统,在本系统中,工具端通过内存泄漏监视界面,远程启动内存泄漏检测系统,即通过动态探针技术,将"动态链接库"中的监视模块插入到被监视进程的地址空间,从而让被监视进程自身具有内存泄漏检测功能,代理服务程序统一处理监视模块收集到的内存信息,同时,将处理结果发送给工具端,工具端经过内存管理模块处理将内存信息实时的可视化到界面上。最后,通过可靠性试验和时间性能试验,验证了该方法的可行性。The programmers of the embedded device in the relay protection field lead to memory leakseasily when the complexity is increasing.It not only will waste a lot of valuable memory resources, but alsoslow down the speed of memory running and even lead to failure of system and device when programmersare not found and resolved. A remote visualization memory leak detection system based on embeddeddevice is designed in order to solve this problem, In this system, the tool side remotely start memory leakdetection module, and insert the monitoring module to the address space of the monitored process throughthe dynamic probe way.So the monitored process has the fuction of memory leak detection.The tool sidereal-time display the memory information processed by the data module to the interface.The reliabilityand timeliness test results prove the feasibility of the method.
