An intelligent addressing program based on the graph theory is adopted in the patrolling robot technology to deal with the multiple intelligent network trend in the monitoring system in unattended substations. The geographical information is represented as an electronic map with nodes correlation matrix. The path searching algorithm based on the transfer closure theory is used to search for the correlation information at all the measuring points. Problems encountered in operation are tested and resolved， with the scheme improved to avoid similar problems in future. With such advantages as freedom from endless loop search， little demand for resources， and high computing speed， this scheme is suitable for on-the-spot real-time test. The high efficiency and feasibility of the scheme is verified through its application in a remote television system using multi-sensor detection.
