A robot applicable to synchronous patrol of a long branch pipeline and a main pipeline includes a walking apparatus and detection apparatuses located on a top of the walking apparatus, where the detection apparatuses accompany the walking apparatus to patrol the main pipeline. The robot further includes a sub-walking apparatus located at a front end of the walking apparatus, where front wheel obstacle-crossing apparatuses of the walking apparatus are also capable of limiting the sub-walking apparatus while crossing an obstacle in the main pipeline, and when the branch pipeline is encountered, the front wheel obstacle-crossing apparatuses are lifted to a certain height, a bin outlet of the sub-walking apparatus is released, and the sub-walking apparatus is separated from the walking apparatus and independently patrols the branch pipeline.

An operation control method suitable for a fire extinguishing system of an extra-high voltage converter station is provided. The method includes: after an upper computer control system receives a sound-light alarm signal, an alarm position signal, and a switch position dividing signal, starting a spray range prediction analysis subsystem for a fixed fire monitor; determining, by the spray range prediction analysis subsystem for the fixed fire monitor based on an external wind direction and an external wind speed, whether a range of a fire monitor effectively covers an entire area of a converter transformer; and if yes, automatically presetting a first fire monitor to which a first compressed air foam generation subsystem belongs and a second fire monitor to which a second compressed air foam generation subsystem belongs; or if no, replacing a fire monitor with a mobile fire-fighting robot to extinguish a fire.
