Method and device for realizing cross-safety-zone data acquisition

The invention discloses a method and a device for realizing cross-safety-zone data acquisition. The method comprises the following steps: acquiring an acquisition domain information table record, an acquisition node information table record and a communication equipment information table record from an information model pre-constructed based on a unified platform; dividing the acquisition node information and the communication equipment information to related acquisition domains according to the acquisition domain information table records; and starting data acquisition service of each acquisition node based on a result divided to the related acquisition domain, and performing data communication with each communication device. The system has the advantages that a plurality of sets of monitoring systems originally deployed in a safety area I, a safety area II and an information area III of a transformer substation or a centralized control station respectively can be unified in one set of system, unified acquis
