Relevance application method and relevance application system for transformer substation remote signaling signals and hard contact terminals

The invention discloses a relevance application method and a relevance application system for transformer substation remote signaling signals and hard contact terminals. The method comprises the following steps: obtaining the serial numbers of the hard contact terminals on remote signaling input plates of a space layer device; extending the attributes of the remote signaling signals according to the original names of the remote signaling signals and the serial numbers of the corresponding hard contact terminals; establishing a maximization model according to the maximum quantity of the remote signaling input plates which can be configured by the space layer device and the attributes of the remote signaling signals; selecting available remote signaling signals from the maximization model for configuration according to the quantity of the remote signaling input plates practically configured by the space layer device in field application. The remote signaling signals are associated with the hard contact terminals, the model of the space layer device is extended, and the searching work efficiency of the secondary circuit of the remote signaling signals is improved.
