Transformer area identification method and device and electronic equipment

The invention discloses a transformer area identification method and device and electronic equipment, relates to the technical field of power grid management, and mainly adopts ultra-narrow band wireless communication and power line carrier communication technologies, and the whole transformer area identification system is composed of a handheld terminal, a monitoring host, a monitoring slave, an ultra-narrow band wireless communication relay station and the like. Comprising the steps that a power line carrier communication signal is broadcasted to a monitoring slave, if the monitoring slave successfully monitors the power line carrier communication signal, a monitoring result corresponding to the monitored power line carrier communication signal is sent to a handheld terminal, and the handheld terminal generates an identification result of a transformer area according to the monitoring result; and if the monitoring slave does not monitor the power line carrier communication signal within the first preset tim
