摘要
针对嵌入式继电保护装置运行期间程序出现故障难以定位,一旦断电重启故障不易重现的问题,对在线故障检测方法进行了研究,并依据此方法设计了一个嵌入式继电保护装置在线调试工具,该工具可实时读取或更改运行中保护装置的变量值,并在装置不断电的情况下注入调试代码,在其运行过程中进行代码级别的调试,有效保持了故障环境,降低了故障定位和问题查找的难度。该工具已成功应用于相关继电保护装置的开发和调试中,验证了方法的可行性。
To solve the problem of the program can not be accurately located during the embedded relay protection device working,and the problem is not easy to reproduce when device is restarted,the fault detection technology was studied. And the on-line debugging tool is designed according to the method,the tool can read and write the device data and inject debug code when the device is running,to provide source-level debugging. These features can keep the faulty environment effectively,and reduce the difficulties in fault location and problem diagnosis. The tool is successfully used in developing and debugging some embedded relay protection device,validates the feasibility and validity.
